Which line is a trend line for the data?​

Answer:

2

Step-by-step explanation:

Answer: 2

Step-by-step explanation: Divide -10 and -5. When you do, the answer will be 2. If you see 2 numbers that both have a negative sign, that means in the end, your answer will be positive. That is why -10/-5 is 2.    

-------------------------------------------------------

-0.25z = -1.25

Multiply both sides by 100:

-0.25z*100=-1.25*100

Refine:

-25z= -125z

Divide both sides by -25:

-25z/-25 = -125/-25

Simplify:

z= 5

Your Answer Is z= 5

Answer:

59 Adults And 147 Children

Step-by-step explanation:

Since there were a total of 206 people, this means that x%2By=206

Also, because "The Jurassic Zoo charges $11 for adult admission and $9 for each child. the total bill for the 206 people from a school trip was $1972", this means that 11x%2B9y=1972

So we have the system:

system%28x%2By=206%2C11x%2B9y=1972%29

Let's solve it by substitution

Now in order to solve this system by using substitution, we need to solve (or isolate) one variable. I'm going to solve for y.

So let's isolate y in the first equation

x%2By=206 Start with the first equation

y=206-x Subtract x from both sides

y=-x%2B206 Rearrange the equation

---------------------

Since y=-x%2B206, we can now replace each y in the second equation with -x%2B206 to solve for x

11x%2B9highlight%28%28-x%2B206%29%29=1972 Plug in y=-x%2B206 into the second equation. In other words, replace each y with -x%2B206. Notice we've eliminated the y variables. So we now have a simple equation with one unknown.

11x%2B%289%29%28-1%29x%2B%289%29%28206%29=1972 Distribute 9 to -x%2B206

11x-9x%2B1854=1972 Multiply

2x%2B1854=1972 Combine like terms on the left side

2x=1972-1854Subtract 1854 from both sides

2x=118 Combine like terms on the right side

x=%28118%29%2F%282%29 Divide both sides by 2 to isolate x

x=59 Divide

-----------------First Answer------------------------------

So the first part of our answer is: x=59

Since we know that x=59 we can plug it into the equation y=-x%2B206 (remember we previously solved for y in the first equation).

y=-x%2B206 Start with the equation where y was previously isolated.

y=-%2859%29%2B206 Plug in x=59

y=-59%2B206 Multiply

y=147 Combine like terms

-----------------Second Answer------------------------------

So the second part of our answer is: y=147

-----------------Summary------------------------------

So our answers are:

x=59 and y=147

This means that 59 adults and 147 children went to the zoo.

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.

Answer:

Answer:

all three options!

Step-by-step explanation:

Answer:

A ladder is leading on a wall that is 4 feet tall. The distance from the bottom of the ladder to the wall is 3 feet wide. Therefore, using the Pythagorean Theorem, 3^2 + 4^2 = 9 + 16 = 25. The square root of 25 is 5. The triangle's hypotenuse or the ladder's length is 5 feet.

The length of the hypotenuse is 25 feet

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.

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.

Step-by-step explanation:

have a great dayy

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%

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%

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

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%.

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.
