Answer:

The number of students Jasmine surveyed indicated they would be traveling during the holiday break is 9.

Step-by-step explanation:

The spinner created by Jasmine, to predict whether a randomly selected student in her school will be traveling during the upcoming holiday break, has 8 equal sections labeled:

{yes, yes, no, no, no, no, no, no}

So, there are two sections labeled yes and six labelled as no.

Compute the probability of a yes as follows:

P(\text{yes})=\frac{2}{8}=0.25

Jasmine selected <em>n</em> = 36 students in her gym class.

If a student in her school will be traveling during the upcoming holiday break is independent of the other students.

Let the random variable <em>X</em> be defined as the number f students that will be traveling during the upcoming holiday break.

The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 36 and <em>p</em> = 0.25.

Compute the expected value of <em>X</em> as follows:

E(X)=np\\=36\times 0.25\\=9

Thus, the number of students Jasmine surveyed indicated they would be traveling during the holiday break is 9.

What is the answer to the problem i need help with?
AveGali [126]

Answer:

C

Step-by-step explanation:

Recall the equation for a circle:

(x-h)^2+(y-k)^2=r^2, where the center is (h,k) and the radius is r.

The given equation is:

(x+5)^2+(y+7)^2=21^2

Another way to write this is:

(x-(-5))^2+(y-(-7))^2=21^2

Thus, we can see that h=-5 and k=-7.

The center is at (-5, -7).

Show all your work to find the axis of symmetry of f(x) = −2(x − 4)^2 + 2.
Naya [18.7K]

Answer:

-2(x^2+15)

Step-by-step explanation:

f(x) = −2(x − 4)^2 + 2.

Expanding (x-4)^2

(x-4)(x+4)

x(x+4)-4(x+4)

x^2+4x-4x-16

x^2-16

F(x) = -2(x^2-16)+2

-2x^2-32+2

-2x^2-30

-2(x^2+15)
