Answer 1

Equation is y=kx.  We have four chance to figure out k; hopefully they all give the same result

x=9, y=63,  y=kx becomes 63=k(9) so k=63/9=7

x=4, y=28, 28=k(4), k=7

The constant of proportionality is 7; we check  2×7=14, 11×7=77

Answer: k=7,   y=7x

Answer 2

Answer:

y=kx

y=k(7)x

y=7x(11)

y=7*11

y=77

Step-by-step explanation:

So with useing the equation that I used the porportional relationship is 7 so just fill 7 in for k. Then take the x number and fill it in for x. you will then multiply and get the y value.

A spinner has four unequal parts. Tony spun the spinner 16 times. The spinner landed on
red 1 time, blue 2 times, yellow 3 times and green 10 times. Using this data, what is the
most likely outcome on the next spin?
red
blue
green
yellow

Answers

Answer:Green

Step-by-step explanation:

Final answer:

Based on past spins, the most likely outcome for the next spin is green, as it was landed on the most frequently.

Explanation:

If a student spun a spinner 16 times and it landed on red 1 time, blue 2 times, yellow 3 times, and green 10 times, the most likely outcome on the next spin would be green.

This conclusion is based on the relative frequency of the outcome for each color so far. The frequency suggests that the spinner is biased toward the green section since it has been landed on the most in this small sample of spins. Assuming the conditions remain the same and there's no alteration to the spinner, the probability of landing on a particular color is proportional to the number of times it has been landed on in the past.

Therefore, with the information provided and based on past occurrences, green is the most likely outcome for the next spin on this specific spinner.

What is the Perimeter of a Rectangle?

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P of rectangle = 2 ( Length + Width )

Given data ,

Let the perimeter of the composite figure be T

Let the rectangle be represented as ABCD

Now , the semicircle is AC

where the perimeter of rectangle P = 12 + 12 + 9

P = 33 yards

And , the circumference of the semicircle C = πr

C = 3.14 x 4.5 = 14.13 yards

So , T = P + C

T = 33 + 14.13

T = 47.13 yd

Hence , the total perimeter of the figure is T = 47.13 yd

What is a function ?

A function is a relationship between inputs and outputs where each input has precisely one output and the output can be linked to its input.

A graph is given which shows a function. We need to find out domain and the range of this function based on the graph.

We know that , in a graph , domain is always represented on the x - axis whereas we represent range on the y - axis. Also , the domain of a function is the input provided to the function whereas the output we get is the range of the function.

In the graph shown : the dots on the x-axis are connected by -5 and 1 . This meant x coordinate is (-5,1) and dots on the y-axis are connected by -4 and 7. This meant y - coordinate is (-4 , 7).

So ,

The domain will be -5 ≤ x ≤ 1 .

The range will be -4 ≤ x ≤ 7 .

Therefore , the domain of the given function is  -5 ≤ x ≤ 1 and range of the given function is  -4 ≤ x ≤ 7.

What is a right-triangle?

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangle-triangle, is a triangle in which one angle is a right angle or two sides are perpendicular.

According to the given problem,

Let us assume,

A pole of length 15 feet cast a shadow of length 20 feet. What is the distance between the tip of the pole and the tip of the shadow?

Now, given,

Perpendicular = 15 feet

Base = 20 feet.

We know,

Hypotenuse² = Perpendicular² + Base²

⇒ H² = 15² + 20²

⇒ H² = 225 + 400

⇒ H² = 625

⇒ H = 25

Hence, we can conclude, the distance from the tip of the pole to the tip of the shadow is 25 feet.

In a math class there are 8 male students and 7 female students. A
student is randomly selected to go to the front office and leaves. A
second student is randomly selected to go to the office. What is the
approximate probability that both students that left were a male
students?
A.25%
B.26.7%
C.28.4%
D.50%​

Answers

Answer: 26.7%

Step-by-step explanation:

The probability that the leftover students were both male is 26.7%. Hence the correct option is B.

The probability that both selected students are male can be calculated as follows:

Determine the probability of selecting a male student for the first pick: P(Male) = 8/(8+7) = 8/15

Since the first student selected was male, the probability of the second student being male as well is: P(Second Male|First Male) = 7/(8+6) = 7/14

Multiply the probabilities together to get the probability of both selected students being male: P(Both Male) = P(Male) * P(Second Male | First Male) = (8/15) * (7/14) = 4/15 or approximately 26.7%

The function f(x) = 185(1.2)x models the number of foxes on a reservation x years from now. What does the 185 represent?

Answers

Answer:

It is the number of foxes in time t=0.

Step-by-step explanation:

If you evaluate f in x=0, you obtain that f(0) = 185*1.2⁰ = 185*1 = 185. This means that after 0 years, the number of foxes on the reservation is 185. In other words, the reservation starts with 185 years and then it grows. 185 here represents, as a result, the value of f, in other words the number of foxes, at time t=0.

The R.R. Bowker Company of New York collects data on annual subscription rates to periodicals. Results are published in Library Journal. In a recent independent study, it was found that 63% of all students at Mill University read Time magazine, 51% read U.S. News and World Report, and 24% read both magazines. If a student at Mill University is randomly selected, what is the probability that the student reads either the Time magazine or the U.S.News and World Report magazine?

Answers

Answer:

90%

Step-by-step explanation:

Let's call the percentage of students that read Time magazine by P(T), and the percentage of students that read U.S News and World Report by P(U). So, we have that:

P(T) = 0.63

P(U) = 0.51

P(T and U) = 0.24

To find the percentage of students that read either the Time magazine or the U.S.News and World Report magazine (that is, P(T or U)), we can use this formula:

P(T or U) = P(T) + P(U) - P(T and U)

So, we have that:

P(T or U) = 0.63 + 0.51 - 0.24 = 0.90

So the probability is 90%

Final answer:

The probability that a randomly selected student at Mill University reads either Time magazine or U.S. News and World Report magazine is 90%.

Explanation:

The student is interested in finding the probability that a Mill University student reads either Time magazine or U.S. News and World Report magazine.

To calculate this, we use the formula for the probability of either event A or B occurring (P(A ∪ B) = P(A) + P(B) - P(A ∩ B)), where P(A ∪ B) represents the probability of A or B happening, P(A) is the probability of A happening, P(B) the probability of B happening, and P(A ∩ B) the probability of both A and B happening.

Given that 63% of students read Time (P(Time) = 0.63), 51% read U.S. News (P(U.S. News) = 0.51), and 24% read both (P(Both) = 0.24), we calculate the probability of a student reading either magazine as P(Either) = P(Time) + P(U.S. News) - P(Both) = 0.63 + 0.51 - 0.24 = 0.90, or 90%.
