rosa, roberto, andrea, and inno find an estamate for the square root of ten who has proposed the best solution

Rosa, use the square root of 9 and the square root of 25
Roberto, use the square root of 4 and the square root of 90
Andrea, use the square root of 11 and the square root of 12
Inno, use the square root of 9 and the square root of 16

Answers

Answer 1
Inno: use the square root of 9 and the square root of 16 10 is between the perfect squares 3^2 = 9 and 4^2 = 16 Rosa's solution of 9 and 25 uses perfect squares but the wider range leaves more room for error. Roberto's as well with the added problem that 90 is not a perfect square and calculating that square root is just as hard as 10. Andrea's solution requires extrapolation which is best avoided if interpolation is an option and 11 and 12 are not perfect squares.
Answer 2

Final answer:

Inno's solution of using the square root of 9 and 16 is the best estimate for the square root of ten, as it provides a narrower and more accurate range for the estimate.

Explanation:

To estimate a square root that is not a perfect square, one strategy is to find integers that the number falls between, and then those integers' respective square roots give us a range within which the square root of the number will fall.

Rosa and Inno's approaches are similar and most appropriate because they both use 9 and another square number that is close to 10.

Rosa uses the square roots of 9 and 25. Since the square root of 9 is 3, and the square root of 25 is 5, we know that √10 is a little more than 3, because 10 is closer to 9 than it is to 25. Inno uses the square roots of 9 and 16. Since the square root of 16 is 4, √10 is closer to 3 than 4 because 10 is closer to 9.

Therefore, Inno's solution gives a closer estimate of the square root of 10, as it falls between 3 and 4 (and closer to 3), and this is the best solution among those proposed.

Use the substitution method to solve the given system of equations. -6y+18=12x and y=3-2x

Answers

We are given that y = 3 - 2x

We will substitute with this value in the second equation as follows:
-6y + 18 = 12x
-6 (3-2x) + 18 = 12x
-18 + 12x + 18 = 12x
This will give us zero = zero

A 0=0 solution means that the system has infinitely many solutions.

Therefore, the answer is (c)

The function f(x) is given by the set of ordered pairs. {(1,0), (–10,2), (0,6), (3,17), (–2,–1)} Which equation is true?

Answers

The correct equation matches the set of ordered pairs of functions:

C.f (0) = 6

Further explanation

Set A to set B is said to be a function if each member of set A pairs is exactly one member of set B

So, one value of x is only assigned to one value of y

or it has only one relationship for each input value

A function can be expressed in the form of a cartesian diagram, the set of ordered pairs, or arrow diagram

If y is a function of x, then y = f (x)

where x is the independent variable and y is the dependent variable

x is the domain and y is the result area or range

A function can be write as ordered pair

Ordered pairs because we write the input first, and then the output

Can be described in form

(input, output)

or

[tex]\large{\boxed{\bold{(x,f (x))}}[/tex]

So A function can be formed as a set of ordered pairs:

For example a set of ordered pairs

(2,4), (3,5), (4,6)

input values ​​(as domain) 2,3,4

output values ​​(as range) 4,5,6.

We complete the questions  with answer choices :

The function f (x) is given by the set of ordered pairs. {(1,0), (–10,2), (0,6), (3,17), (–2, –1)}:Which equation is true?

f(-10)=1

f(2)=-10

f(0)=6

f(1)=-10

Let see  the answer choices :

f (-10) = 1

values ​​x = -10, f (x) = y = 1, ordered pairs (-10,1)

f (2) = - 10

values ​​x = 2, f (x) = y = -10, ordered pairs (2, -10)

f (0) = 6

value x = 0, f (x) = y = 6, ordered pairs (0.6)

f (1) = - 10

values ​​x = 1, f (x) = y = -10, ordered pairs (1, -10)

So the answer choices that correspond to the set of ordered pairs of functions above are choices C.f (0) = 6

What is the factored form of the expression 3×2+8×-16

Answers

We want to factor 3x² + 8x - 16.

Note that
16 = 1 x 16
    = 2 x 8

By using 16 = 4 x 4, obtain
(3x)(4) - (x)(4) = 12x - 4x = 8x
This produces 8x in the given expression.

Therefore
3x² + 8x - 16 = (3x - 4)(x + 4)

There are two sizes of trucks available: larger truck with a 2.5-ton payload, and smaller trucks with 1.5-ton payload. To unload a freight train 21 larger trucks are needed . How many smaller trucks would be needed for the same job?

Answers

You can find the answer to this question by multiplying 21 by 2.5 to find the total weight ton which would be 52.5, then you would divide 52.5 by 1.5 to find the number of small trucks needed to equal 52.5 ton which would be 35 smaller trucks. So your answer should be 35 smaller trucks are needed to do the same job.

A jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles. You pick one marble from the jar at random. What is the theoretical probability of picking a green marble

Answers

So, if the jar has 20 yellow marbles, 55 green marbles, and 25 purple marbles in total it has 100 marbles. (check:20+55+25=100m). Sense there are 55 green marbles out of 100, your theoretical probability will be 550/100(fraction:55 over 100). Simplified its 11/20. 

Answer:

The theoretical probability of picking a green marble is 0.55.   Step-by-step explanation:

Given : A jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles. You pick one marble from the jar at random.

To find : What is the theoretical probability of picking a green marble?

Solution :

Theoretical probability is defined as the number of favorable outcome divided by total number of outcome.

Yellow Marble = 20

Green Marble = 55

Purple Marble = 25

Total Number of marble = 20 + 55 + 25 = 100

Let G be the event of getting green marble.

So, Favorable outcome = 55

Theoretical probability of picking a green marble is

[tex]P(G)=\frac{55}{100}[/tex]

[tex]P(G)=\frac{11}{20}[/tex]

[tex]P(G)=0.55[/tex]

Therefore, The theoretical probability of picking a green marble is 0.55.

There are 12 peas left in Daphne's bowl and 7 peas squished in her hair.

Now,

Since, There are 12 peas left in Daphne's bowl and 7 peas squished in her hair.

Hence, The ratio of peas in Daphne's bowl to peas in her hair will be;

⇒ Ratio = Number of peas in bowl / Number of peas in her hair

At one college, GPA's are normally distributed with a mean of 2.7 and a standard deviation of 0.5. What percentage of students at the college have a GPA between 2.2 and 3.2?

Answers

Final answer:

About 68.27% of students at the college have a GPA between 2.2 and 3.2 because these values correspond to z-scores of -1 and +1, respectively, in a normal distribution.

Explanation:

To find the percentage of students at the college who have a GPA between 2.2 and 3.2, we will use the properties of the normal distribution. The mean GPA is 2.7 and the standard deviation is 0.5.

First, we calculate the z-scores for the GPAs of 2.2 and 3.2:

z-score for 2.2 = (2.2 - 2.7) / 0.5 = -1

z-score for 3.2 = (3.2 - 2.7) / 0.5 = +1

The z-score represents the number of standard deviations a data point is from the mean. In a standard normal distribution, the percentage of data between z-scores of -1 and +1 is approximately 68.27%.

Therefore, about 68.27% of the students at the college have a GPA between 2.2 and 3.2.

Given A = {18, 6, -3, -12} Determine all elements of set A that are in the solution of the inequality 2/3x + 3 < -2x -7

Answers

Plug in each value in the set into x, and evaluate both sides.
The values of x that make the inequality true are the answer.

Start with 18.
2/3x + 3 < -2x -7
2/3(18) + 3 < -2(18) - 7
12 + 3 < -36 - 7
15 < -43 is false, so 18 does not work.

Now do 6.
2/3x + 3 < -2x -7
2/3(6) + 3 < -2(6) - 7
4 + 3 < -12 - 7
7 < -19 is false, so 6 does not work.

Now do -3.
2/3x + 3 < -2x -7
2/3(-3) + 3 < -2(-3) - 7
-2 + 3 < 6 - 7
1 < -1 is false, so -3 does not work.

Now do -12.
2/3x + 3 < -2x -7
2/3(-12) + 3 < -2(-12) - 7
-8 + 3 < 24 - 7
-5 < 17 is true, so -12 does not work.

When using substitution, we are imputing an equation in place of a variable to eliminate one of the variables in the equation so that we can solve for the remaining variable.

For this example, we will be plugging in (-4y+12) wherever "x" is in the other equation.

3/4 x -5y = 7
3/4(-4y+12) -5y =7
((3/4)(-4y))+((3/4)12)-5y=7
-3y+9-5y=7
-8y= -2
y=(1/4)


Now find "x" by plugging in the y-value.
x=(-4*(1/4))+12
x= -1 +12
