After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm. A state engineer believes that estimate is too low. The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?

Answers

Answer 1

Answer:

D

Step-by-step explanation:

The null hypothesis is that p=0.19. The engineer says that this estimate is too low, meaning he believes the true proportion is greater than 0.19 - p>0.19. Because this is a proportion of ALL houses in the state, we use p rather than phat, leaving D as the correct answer.

The vertex of a quadratic function is (6, 2), and the y-intercept of the function is (0, −70). The equation of the function in vertex form, f(x)=a(x−h)2+k, is shown.−70=a(0−6) squared+2

Answers

Answer:

The equation of the function in vertex form is represented by [tex]y = -2\cdot (x-6)^{2}+2[/tex].

Step-by-step explanation:

Let [tex](h,k) = (6,2)[/tex] and [tex](x,y) = (0, - 70)[/tex], now we substitute on the equation of the quadratic function and solve for [tex]a[/tex]:

[tex]y = a\cdot (x-h)^{2}+k[/tex]

[tex]-70 = a\cdot (0-6)^{2}+2[/tex]

[tex]-70 = 36\cdot a + 2[/tex]

[tex]36\cdot a = -72[/tex]

[tex]a = -2[/tex]

Therefore, the equation of the function in vertex form is represented by [tex]y = -2\cdot (x-6)^{2}+2[/tex].

[tex]\huge\boxed{\tt{x = -5 , y = 2}}[/tex]

Step-by-step explanation:

x = y - 7   ---------------------(1)

-y - 2x = 8 --------------------(2)

Put Equation (1) into (2)

- y - 2 ( y-7 ) = 8

-y - 2y + 14 = 8

-3y = 8 - 14

-3y = -6

Divide -3 to both sides

y = -6 / -3

y = 2

Put y = 2 in (1)

x = 2 - 7

x = -5

So,

x = -5 , y = 2

Key skills needed: Solving one variable equations

1) we have the equation --> 12.72 = 5.52 + 8x

2) We need to solve for x.

To get x by itself, we subtract 5.52 from  both sides.  (12.72 - 5.52 = 7.2)

This means 8x = 7.2

3) Divide by 8 from both sides, and you will get x = 0.9 (7.2/8 = 0.9)

The length of which line segment is equal to the exact value of the sine if theta?

Option 3: line segment OR
Option 4: line segment OS​

Answers

Answer: Option 2. Segment TS

====================================================

Explanation:

Recall that the sine of an angle is equal to the ratio of opposite over hypotenuse.

In other words,

sin(angle) = opposite/hypotenuse

With respect to reference angle theta, the side TS is opposite this angle. It is the leg furthest from the angle. The hypotenuse is the longest side segment TO. The hypotenuse is always opposite the 90 degree angle.

For a unit circle, the radius is 1, so segment TO is 1 unit long.

Therefore,

sin(angle) = opposite/hypotenuse

sin(theta) = TS/TO

sin(theta) = TS/1

sin(theta) = TS
