Three friends all live on the same street that runs west to east. Ben lives 4 blocks from Ann. Carl lives 2 blocks from Ben. If the street is represented by a number line and Ann's house is located at 0, what are the possible locations for Carl's house?
Answers
Answer:
The possible locations are,
2, -2, 6 or -6
Step-by-step explanation:
Given,
The location of Ann's house in the number line = 0,
∵ Ben lives 4 blocks from Ann.
So, the possible location of Ben's house = 4 ( right of ann's house ) or - 4 ( left of ann's house )
Now, Carl lives 2 blocks from Ben,
So, the possible location of Carl's house
Case 1 : If Ben's house location is 4 = 2 ( left of ben's house ) or 6 ( right of ben's house )
Case 2 : If Ben's house location is -4 = -2 ( right of ben's house ) or -6 ( left of ben's house )
The possible locations of Carl's house are - 6, 6, 2 or - 2
Let :
Ben's location = B
Carl's position = C
Ann's position = A
Using the Number line illustration :
Ann's position = 0
Ben's possible positions :
4 blocks(units) from Ann = ± 4Carl's location :
2 blocks from Ben-4 ± 2 = (-4 - 2) or (-4 + 2) = - 6 or - 2 +4 ± 2 = (4 + 2) or (4 - 2) = 6 or 2Learn more : https://brainly.com/question/16191404?referrer=searchResults

Marko currently has 20 tulips in his yard. Each year he plants 5 more. Write an explicit formula for the number of tulips Marko has.
Predict the number of tulips Marko will have in 7 years.
Answers
To write an explicit formula for the number of tulips Marko has, use the formula n = a + (x-1)d, where n represents the number of tulips, a is the initial number of tulips, x is the number of years, and d is the change in number of tulips each year. The explicit formula for Marko's tulips is n = 20 + 5(x-1). To predict the number of tulips Marko will have in 7 years, substitute x = 7 into the formula and solve for n, giving Marko will have 50 tulips in 7 years.
Explanation:To write an explicit formula for the number of tulips Marko has, we can use the formula: n = a + (x-1)d. Here, n represents the number of tulips, a is the initial number of tulips (20), x is the number of years, and d is the change in number of tulips each year (5). So, the explicit formula is n = 20 + 5(x-1).
To predict the number of tulips Marko will have in 7 years, we can substitute x = 7 into our formula: n = 20 + 5(7-1). Solving this equation, we get n = 20 + 5(6) = 20 + 30 = 50. Therefore, Marko will have 50 tulips in 7 years.

A bottle of medicine contains 40 doses. How many doses are in 3 1/3 bottles?
Answers
To calculate the total number of doses in 3 1/3 bottles of medicine, multiply the fraction of bottles (10/3) by the number of doses per bottle (40). The result is 133 1/3 doses.
Explanation:The student is asking how many doses are in 3 1/3 bottles of medicine if one bottle contains 40 doses. To find the answer, we need to multiply the number of bottles by the number of doses per bottle.
Here is the step-by-step calculation:
First, convert 3 1/3 bottles to an improper fraction: 3 1/3 = (3 × 3 + 1)/3 = 10/3 bottles.Next, multiply this value by the number of doses in one bottle to find the total number of doses: (10/3) × 40 doses = 400/3 doses.Finally, simplify the fraction: 400/3 doses = 133 1/3 doses.So, there are 133 1/3 doses in 3 1/3 bottles of medicine.
As sand leaks out of a hole in a contaimer, it forms a conical pile whose altitude is always the same as its radius. If the height of the pile is increasing at a rate of 6in/min, find the rate at which sand is leaking out when the altitude is 10 inches.

What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
The volume of a cone is (1/3)πr²h.
We have,
A conical pile formed due to a leak out of a hole whose radius is equal to its height.
dh/dt = 6 in/min
The rate at which the sand is leaking when height is 10 inches.
We have,
Volume = (1/3)πr²h and h = 10 inches
V = 1/3 πh²h
V = 1/3 πh³
Differentiating both sides.
dV/dt = 1/3 x π x 3 x h² (dh/dt)
dV/dt = π x h² x 6
dV/dt = π x 10² x 6

If a polynomial function f(x) has roots 3 and mc001-1.jpg, what must also be a root of f(x)?
Answers
The Complex Conjugate Root Theorem dictates that if -4 is a root of f(x), then 4 must also be a root. This theorem applies to polynomials with real coefficients, ensuring non-real complex roots appear in conjugate pairs.
Explanation:If a polynomial function f(x) has roots 3 and -4, then by the Complex Conjugate Root Theorem (also known as the Conjugate Pairs Theorem), if the polynomial has real coefficients, which is the usual assumption unless stated otherwise, the complex roots must come in conjugate pairs. Therefore, if -4 is a root, its complex conjugate 4 must also be a root of f(x). This applies to all non-real complex roots of a polynomial with real coefficients.
The Complex Conjugate Root Theorem is essential for understanding the behavior of polynomial functions with complex roots. In general, if a polynomial has a complex root a + bi, where a and b are real numbers and i is the imaginary unit (the square root of -1), its conjugate a - bi is also a root. This is true because polynomial equations with real coefficients have the property that their roots are either real or occur in complex conjugate pairs.

Evaluate the line integral, where c is the given curve. (x + 9y) dx + x2 dy, c c consists of line segments from (0, 0) to (9, 1) and from (9, 1) to (10, 0)
Answers
The first line segment can be parameterized by [tex]\mathbf r_1(t)=\langle0,0\rangle(1-t)+\langle9,1\rangle t=\langle9t,t\rangle[/tex] with [tex]0\le t\le1[/tex]. Denote this first segment by [tex]C_1[/tex]. Then
[tex]\displaystyle\int_{C_1}\langle x+9y,x^2\rangle\cdot\mathbf dr_1=\int_{t=0}^{t=1}\langle9t+9t,81t^2\rangle\cdot\langle9,1\rangle\,\mathrm dt[/tex]
[tex]=\displaystyle\int_0^1(162t+81t^2)\,\mathrm dt[/tex]

The second line segment ([tex]C_2[/tex]) can be described by [tex]\mathbf r_2(t)=\langle9,1\rangle(1-t)+\langle10,0\rangle t=\langle9+t,1-t\rangle[/tex], again with [tex]0\le t\le1[/tex]. Then
[tex]\displaystyle\int_{C_2}\langle x+9y,x^2\rangle\cdot\mathrm d\mathbf r_2=\int_{t=0}^{t=1}\langle9+t+9-9t,(9+t)^2\rangle\cdot\langle1,-1\rangle\,\mathrm dt[/tex]

Finally,
[tex]\displaystyle\int_C(x+9y)\,\mathrm dx+x^2\,\mathrm dy=108-\dfrac{229}3=\dfrac{95}3[/tex]
To evaluate the given line integral, you need to parameterize the curve composed of two segments. Then, you solve the integrals along the two separate segments and take the sum.
Explanation:To evaluate the line integral where the curve c consists of line segments from (0, 0) to (9, 1) and from (9, 1) to (10, 0) for the function (x + 9y) dx + x² dy, we need to parameterize the curve and solve the integral.
First, we parametrize the line segments. For the segment from (0, 0) to (9, 1), we have x = 9t and y = t for t in [0, 1]. For the segment from (9, 1) to (10, 0) let x = 9 + s and y = 1 - s for s in [0, 1].
Then, we integrate along the first and second segments separately with respect to t. For the first segment, the integral is ∫(9t + 9t) d(9t) + ∫(81t²) dt = ∫18t dt + ∫81t² dt. For the second segment, the integral is ∫(9 + s + 9(1 - s)) ds + ∫(81 + 2 * 9 * s + s²) d(1 - s) = ∫ds + ∫s² ds.
We then evaluate these integrals over the respective bounds, sum them up and that gives the line integral along the path described.

Focus on the first Magic Square for now (the one in the top row, left side).
The middle row has 9+6+3 = 18 as the magic constant (aka magic sum). Every row, column and diagonal must add to this constant
A = 7 because the first column of values must add to 18
A+9+2 = A+11 = 18 leads to A = 7
----------
C = 10 since that solves 2+6+C = 18 (northeast diagonal)
----------
Solve the equation A+6+E = 18 for E to get E = 5 (plug in A = 7)
As a check, note how C+3+E = 10+3+5 = 18
----------
We know that A = 7 and C = 10 so B must be B = 1 since A+B+C = 7+1+10 = 18
----------
Similarly, 2+D+E = 18 and E = 5, so D must be 11.
As a check, note how B+6+D = 1+6+11 = 18

If it snows on game day there is a 32% chance the Jets will win. If it does not snow on game day there is a 41% chance the jets will win. There is a 29% chance that it will snow on game day.
a. What is the probability the Jets will win?
b. What is the probability that it snows on game day and the Jets win?
c. What is the probability that it snows on game day given that the Jets win?
Answers
To find the probability the Jets will win, we use the Law of Total Probability. The probability that it snows on game day and the Jets win is found using the definition of conditional probability. Lastly, to find the probability that it snows on game day given that the Jets win, Bayes' theorem is used.
Explanation:To solve this problem, we can use the concept of conditional probability. Let's define the following events:
A = it snows on game day
B = the Jets win
We are given:
P(B|A) = 0.32 (the probability of the Jets winning if it snows)
P(B|A') = 0.41 (the probability of the Jets winning if it doesn't snow)
P(A) = 0.29 (the probability of it snowing on game day)
To find the probability of the Jets winning, we can use the Law of Total Probability:
P(B) = P(B|A)P(A) + P(B|A')P(A')
P(B) = 0.32 * 0.29 + 0.41 * (1 - 0.29)
P(B) = 0.0928 + 0.1059
P(B) ≈ 0.1987
To find the probability that it snows on game day and the Jets win, we can use the definition of conditional probability:
P(A and B) = P(A) * P(B|A)
P(A and B) = 0.29 * 0.32
P(A and B) ≈ 0.0928
To find the probability that it snows on game day given that the Jets win, we can use Bayes' theorem:
P(A|B) = (P(B|A) * P(A)) / P(B)
P(A|B) = (0.32 * 0.29) / 0.1987
P(A|B) ≈ 0.4643

x+8 = 0
(x+2 )(x+2)=0 (double root)
The polynomial equation will be
(x+8)(x+2 )(x+2 )=0
(x+8)( x² +4+4x) = 0
x³ +4x+4x²+8x²+32+32x = 0
x³ +12x² +36x+32 =0
Therefore the polynomial equation will be x³ +12x² +36x+32 =0

Of all numbers whose difference is 4, find the two that have the minimum product.
Answers
The two numbers whose difference is 4 will be +2 and -2. The two have the minimum product is -4.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that, there are two numbers whose difference is 4 and it must have a minimum product.
We have to apply arithmetic operation operations in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
Suppose one number is x and the other x−4.
The minimum product is,
=x(x−4)
=x²−4x
Differentiate both sides to obtain minimum value,
=2x-4
2x=4
x=2
The other number is,
=x−4
=2-4
=-2
Thus, the two numbers whose difference is 4 will be +2 and -2. The two have the minimum product is -4.

Amy Jo found that the perimeter of a square was 53.2 square inches. What is the side length of the square?
Answers
perimeter of a square is 4 times side length (4s)
to find the length of a side divide the perimeter by 4
53.2 / 4 = 13.3
so each side is 13.3 inches

Answers
Answer: B. [tex]48.5\%[/tex]
Step-by-step explanation:
Given : A number cube is rolled with these results:
64 ones, 67 twos, 73 threes, 59 fours, 72 fives, and 71 sixes.
Even numbers : 2,4,6
The number of times of rolling even number = [tex]67+59+71=197[/tex]
Total outcomes = [tex]64+67+73+59+72+71=406[/tex]
Now, the experimental probability of rolling an even number :-
[tex]\dfrac{197}{406}[/tex]
In percent, [tex]\dfrac{197}{406}\times100=48.52216748\approx48.5\%[/tex]
Hence, the experimental probability of rolling an even number = [tex]48.5\%[/tex]

You have 2/3 of a pizza. You divide the remaining pizza into 4 equal pieces. What fraction of the pizza is each piece?
Answers
Keep in mind that when you divide by a number, you are actually multiplying by its reciprocal.
The reciprocal of 4 is 1/4.
2/3 * 1/4 = 2/12
2/12, when simplified, is equal to 1/6.
So each remaining slice is equal to 1/6.
Hope this helps.

If µ = 400 and s = 100 the probability of selecting at random a score less than or equal to 370 equals ____.
Answers
The probability of selecting at random a score less than or equal to 370 is approximately 0.3821.
To find the probability of selecting at random a score less than or equal to 370 from a normal distribution with a mean [tex](\( \mu \))[/tex] of 400 and a standard deviation [tex](\( s \))[/tex] of 100, we can use the z-score formula and the standard normal distribution table.
The z-score formula is given by:
[tex]\[ z = \frac{x - \mu}{s} \][/tex]
Where:
- x is the value of the random variable (370 in this case)
- [tex]\( \mu \)[/tex] is the mean (400)
- s is the standard deviation (100)
Substituting the given values into the formula:
[tex]\[ z = \frac{370 - 400}{100} = -0.3 \][/tex]
Now, we look up the probability corresponding to z = -0.3 in the standard normal distribution table. The probability of selecting a score less than or equal to 370 is the cumulative probability up to z = -0.3.
From the standard normal distribution table, the cumulative probability corresponding to z = -0.3 is approximately 0.3821.
Therefore, the probability of selecting at random a score less than or equal to 370 is approximately 0.3821.
