Answer: Choice D. y = (x-1)^2 - 3

The vertex is (h,k) = (1,-3). So h = 1 and k = -3.

We have a = 1 as the leading coefficient.

Plug those values into the equation below

y = a(x-h)^2 + k

y = 1(x - 1)^2 + (-3)

y = (x - 1)^2 - 3

If a tellemarketer made 200 phone calls and 35 customers signed up what is the relative frequency of getting a customer and not
Snezhnost [94]

Answer:

82.5% and 17.5%

Step-by-step explanation:

The telemarketer made 200 phone calls and only 35 people signed up. Therefore, we need to find the amount of people who didnt.

200 - 35 = 165

165 people did not sign up.

This meants that the frequency of getting a customer is 35/200 and not is 165/200. In percentages,

The relative frequency of not getting a customer is 82.5%

The relative frequency of getting a customer is 17.5%

Franklin measured and labeled the angles of a triangle as shown. Jennifer says that at least one of his measures is incorrect. E
ioda

Answer:

see the explanation

Step-by-step explanation:

First way

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

so

In this problem

37+97+134 > 180

therefore

At least one of Franklin's measures is incorrect

Second way

we know that

A triangle can only have at most one obtuse internal angle.

In this problem the triangle has two obtuse internal angles

Remember that an obtuse angle is an angle greater than 90 degrees

therefore

At least one of Franklin's measures is incorrect
