The rate of change of the function can be determined by finding the slope of the function at different points in the table.
Explanation:The rate of change of a function can be determined by finding the slope of the function at different points. In this case, we can use the values provided in the table to find the rate of change. The rate of change is equal to the difference in the y-values divided by the difference in the x-values.
Let's take the first two points in the table as an example. The first point is (12/5, 5) and the second point is (5, 25/2). The difference in the y-values is 25/2 - 5 = 15/2, and the difference in the x-values is 5 - 12/5 = 23/5. Therefore, the rate of change is (15/2) / (23/5) = 15/2 * 5/23 = 75/46. So, the rate of change of the function for these two points is 75/46.
A spinner has five congruent sections, one each of blue,green,red,orange, and yellow. Yuri spins the spinner 10 times and records his results in a table.
Which statements are true about Yuri’s experiment? Check all that apply
Answer: 1st, 3rd and 5th answers are correct
Step-by-step explanation:
Answer:
A) The theoretical probability of spinning any one of the five colors is 20%.
C) The theoretical probability of spinning green is equal to the experimental probability of spinning green.
E) If Yuri spins the spinner 600 more times and records results, the experimental probability of spinning orange will get closer to the theoretical probability of spinning orange.
Step-by-step explanation:
Let's find the probability of each events.
Probability of a event = The number of favorable outcomes / The total number of possible outcomes.
Here the total number of possible outcomes = 10.
Probability of getting blue = 1/10 = 0.10
Probability of getting green = 2/10 = 1/5= 0.20 = 20%
Probability of getting red = 0/10 = 0
Probability of getting orange = 4/10 = 0.40
Probability of getting yellow = 3/10 = 0.30
The above are the experimental probability.
The theoretical probability of getting green = 1/5 = 0.20 = 20%
By looking at the results, the following statements are true.
A) The theoretical probability of spinning any one of the five colors is 20%.
C) The theoretical probability of spinning green is equal to the experimental probability of spinning green.
E) If Yuri spins the spinner 600 more times and records results, the experimental probability of spinning orange will get closer to the theoretical probability of spinning orange.
How do you find a quadratic function that has a minimum value of -12
Answer:
Step-by-step explanation:
A quadratic equation is an expression that has an x^2 term. Quadratic equations are most commonly expressed as ax^2+bx+c, where a, b and c are coefficients. Coefficients are numerical values. For example, in the expression 2x^2+3x-5, 2 is the coefficient of the x^2 term. Once you have identified the coefficients, you can use a formula to find the x-coordinate and the y-coordinate for the minimum or maximum value of the quadratic equation.
Determine whether the function will have a minimum or a maximum depending on the coefficient of the x^2 term. If the x^2 coefficient is positive, the function has a minimum. If it is negative, the function has a maximum. For example, if you have the function 2x^2+3x-5, the function has a minimum because the x^2 coefficient, 2, is positive.
Divide the coefficient of the x term by twice the coefficient of the x^2 term. In 2x^2+3x-5, you would divide 3, the x coefficient, by 4, twice the x^2 coefficient, to get 0.75.Multiply the Step 2 result by -1 to find the x-coordinate of the minimum or maximum. In 2x^2+3x-5, you would multiply 0.75 by -1 to get -0.75 as the x-coordinate.
Plug in the x-coordinate into the expression to find the y-coordinate of the minimum or maximum. You would plug -0.75 into 2x^2+3x-5 to get 2_(-0.75)^2+3_-0.75-5, which simplifies to -6.125. This means the minimum of this equation would be x=-0.75 and y=-6.125.
If there is not a number before a variable, the coefficient is 1. For example, if your expression is x^2+5x+1, the x^2 coefficient is 1.

Use the distributive property to remove the parentheses.
[tex]6(2 - u) \\ [/tex]
what is the answer???
Answer:
12-6u
Step-by-step explanation:
To remove the parenthesis, we must multiply the number on the outside to each value within the parenthesis
This means that
[tex]6(2-u)\\\\6*2-6*u\\\\12-6u[/tex]
The distributive property is used to remove parentheses by multiplying each term within the parentheses by the number outside. Thus, the expression 6(2 - u) becomes 12 - 6u.
Explanation:The distributive property is a mathematical principle that shows how to expand an expression involving brackets (or parentheses). To use the distributive property to remove the parentheses in the expression, you multiply the number outside the parentheses by each term inside the parentheses individually. Let's apply this to the expression you provided, 6(2 - u).
First, multiply 6 by 2. This results in 12. Next, multiply 6 by -u. This gives -6u. Therefore, the expression 6(2 - u) without parentheses, using the distributive property, is 12 - 6u.

A puppy and a kitten are 180 meters apart when they see each other. The puppy can run at a speed of 25 m/sec, while the kitten can run at a speed of 20 m/sec.
How soon will the kitten catch the puppy if the kitten starts running after the puppy?
Make two equations representing the position of each animal, p and k, for the puppy and kitten respectively.
p=25t and k=180+20t
The puppy will catch the kitten when p=k so we can say:
25t=180+20t subtract 20t from both sides
5t=180 divide both sides by 5
t=36
So the puppy will catch the kitten after 36 seconds.

Answer:
c = 14
Step-by-step explanation:
For this triangle we have to
[tex]a=18.2\\B=62\°\\C=48\°[/tex]
We want to find the length of b
We know that the sum of the internal angles of a triangle is 180 °
then
[tex]A + 62 +48=180\\\\A=180-62-48\\\\A=70\°[/tex]
Now we use the sine theorem to find the length of c:
[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]
Therefore:
[tex]\frac{sin(A)}{a}=\frac{sin(C)}{c}\\\\c=\frac{sin(C)}{\frac{sin(A)}{a}}\\\\c=a*\frac{sin(C)}{sin(A)}\\\\c=(18.2)\frac{sin(48)}{sin(70)}\\\\c=14[/tex]
Answer:
c= 14
Step-by-step explanation:
First, let's find the angle A, because it's easy and because we'll need it.
We know that the sum of the interior angles of a triangle is 180, and we have 2 angles... so we can easily find A:
A = 180 - 62 - 48 = 70 degrees
Now, we can use the law of Sines to find c:
[tex]\frac{c}{sin(C)} = \frac{a}{sin(A)}[/tex]
so...
[tex]c = \frac{a * sin(C)}{sin(A)} = \frac{18.2 * sin(48)}{sin(70)} = 14.39[/tex]
The precise answer is 14.39, but you are asked to round up to the closest whole number... so 14.
A rectangular prism has a volume of 540, if the length, width and height are all reduced 1/3 the size of the original. What is the new volume?
Answer:
20 units³
Step-by-step explanation:
Since all dimensions are being reduced by 1/3, that means that the total volume will decrease by 1/3 * 1/3 * 1/3 = 1/27 the size of its original.
That means that the new volume is 1/27 * 540 = 20 units³

Answer:
$17.35/h
Step-by-step explanation:
In order to get the amount per hour he made, you first need to calculate the global amount of money he made.
He was paid $2,900 then he had costs of $1,200, that leaves him a net income of $1,700 ($2,900 - $1,200)
Then he worked a total of 98 hours for that money.
A salary is an amount of money expressed by a period of time. In this case, we'll use hours.
So, Jonah earned $1,700 after 98 hours of work:
S = $1,700 / 98 hours = $17.35/h

A steel cargo container is shaped like a cube measuring 5.2 ft on each edge how much steel is needed to make this container? Show your work.
Answer:
162.24 ft
Step-by-step explanation:
So you first find the area of one side.
5.2 x 5.2 = 27.4
Then you times it by 6, because a cube has 6 sides.
27.4 x 6 = 162.24 ft
A steel cargo container is shaped like a cube measuring 5.2 ft on each edge. we will need 162.24 ft sq. steel to make this container.
How to find the surface area of a cube?A cube has all sides congruent, so all sides have the same area.
Supposing that the considered cube has a side length (also called edge length) of L units.
Then, its one side's area equals L^2 sq. units (as each side is a square, so we used the formula for the area of a square).
Since there are 6 such sides in a closed cube, thus, its surface area evaluates to
[tex]S = L^2 + L^2 + ... + L^2 \text{\: (six times)} = 6L^2 \: \rm unit^2[/tex]
A steel cargo container is shaped like a cube measuring 5.2 ft on each edge.
So first we need to find the area of one side.
The area of a square = 5.2 x 5.2

(x 3/2)6
For this case we must simplify the following expression:
[tex](x ^ {\frac {3} {2}}) ^ 6[/tex]
We have that by definition of properties of powers that is fulfilled:
[tex](a ^ n) ^ m = a ^ {n * m}[/tex]
Then, rewriting the expression:
[tex]x ^ {\frac {3 * 6} {2}} =\\x ^ {\frac {18} {2}} =\\x ^ 9[/tex]
Answer:
[tex](x^{\frac{3}{2}})^6=x^9[/tex]
Final answer:
To simplify the expression [tex](x^{3/2)6[/tex], use the power rule of exponents to get x to the power of 9, which is the simplified form of the expression.
Explanation:
To simplify the expression [tex](x^{3/2)6[/tex], we need to apply the power of a power property, which states that when you raise a power to another power, you multiply the exponents.
So, we have:
[tex](x^{3/2)6[/tex] = [tex]x^{(3/2)\times 6[/tex]
= [tex]x^{3\times 3[/tex]
= x⁹
Therefore, [tex](x^{3/2)6[/tex] simplifies to x⁹.
This means that the expression is equivalent to x raised to the power of 9.
In summary, when you raise x to the power of 3/2 and then raise that result to the power of 6, you end up with x raised to the power of 9.
A prescription calls for erythromycin 40 mg/kg/day and the patient is a child that weighs 44 pounds. How many mg of erythromycin would the patient need to take per dose if there are 4 doses per day?
A. 10 mg
B. 200 mg
C. 2 mg
D. 40 mg
Answer:
B
Step-by-step explanation:
We know 2.2 pounds = 1 kg, hence,
44 pounds / 2.2 = 20 kg (weight of child in kg)
Now, since 40 mg is administered per kg, the child would need 40 * 20 = 800 mg PER DAY
Since this is going to be taken per 4 dose, each dose would need to be 800/4 = 200 mg
Answer choice B is right.

There are 9 students in a class: 2 boys and 7 girls. If the teacher picks a group of 4 at random, what is the probability that everyone in the group is a girl?
Answer:
28% probability that every student in the group is a girl.Step-by-step explanation:
In this problem we have independent events, that is, the event "picking a girl" doesn't affect an "picking a boy", also, picking picking a girl doesn't affect the probability of the other subjects.
So, the probability when the first girl is being picked is:
[tex]P_{1}=\frac{7 \ girls}{9 \ students}[/tex]
Because among the total 9 students, there are 7 girls.
Now, after picking one girl, there remains 6 girls and 8 students to be picked. So, the probability of the second girl would be:
[tex]P_{2}=\frac{6 \ girls}{8 \ students}[/tex]
Then, the probability of the third girl:
[tex]P_{3}=\frac{5 \ girls}{7 \ students}[/tex]
The fourth girl probability:
[tex]P_{3}=\frac{4 \ girls}{6 \ students}[/tex]
Therefore, the probability of picking all 4 girls would be the product of each probability, because events are independent (we use product when they are independent):
[tex]P=\frac{7 \ girls}{9 \ students} \times \frac{6 \ girls}{8 \ students} \times \frac{5 \ girls}{7 \ students} \times \frac{4 \ girls}{6 \ students}\\P=\frac{5}{18}=0.28 \ (or \ 28\%)[/tex]
Therefore, there's 28% probability that every student in the group is a girl.
The probability that everyone in the group is a girl is 0.2778
How to determine the probability?The distribution of the students is given as:
Boys = 2
Girls = 7
Total = 9
The selection of the 4 girls at random is:
7 girls from 9 students6 girls from the remaining 8 students5 girls from the remaining 7 students4 girls from the remaining 6 studentsSo, the probability that all students are girls is:
P = 7/9 * 6/8 * 5/7 * 4/6

P = 0.2778
Hence, the probability that everyone in the group is a girl is 0.2778
