Remark

I think you can only do this either as a 2 step question or as a proportion. The easiest way is the proportion.

Proportion

6 hours / 52.50 = 11/x Cross multiply

6*x = 52.50 * 11 Combine the factors on the right

6x = 577.5 Divide both sides by 6

6x/6 = 577.5/6

x = 96.25 Answer

So, just divide:

52.50 / 6 = 8.75

This means that she earns $8.75 an hour.

If this is her hourly salary, then multiply 8.75 x 11

8.75 x 11 = 96.25

So, if Paula works for 11 hours, she will earn $96.25!

Given f(x) = -3x + 5, find the value for f (7).

Lorico [155]

Answer:

-16.

Step-by-step explanation:

Given that f(x) = $-3 times x$ + 5.

We need to find the value of f(7).

Hence we need to put x = 7 in the given function.

Hence f(7) = $-3 times 7$ + 5 = -16.

Consider a hypothesis test to decide whether the mean annual consumption of beer in the nation's capital is less than the nation

vazorg [7]

Answer:

Step-by-step explanation:

Type I error occurs when the null hypothesis is rejected even when it is true.

Type II error occurs when the null hypothesis is not rejected even when it is false.

The null hypothesis is

The mean annual consumption = the national mean

The alternative hypothesis is

The mean annual consumption < the national mean

1) it is a type II error because the null hypothesis was not rejected even when it is false

2) it is a correct decision because the decision corresponds to the outcome

3) it is also a type II error

d) it is a correct decision because the null hypothesis is accepted when it is true

Verify sinx/1-cosx + sinx/1+cosx = 2cscx

Andru [333]

$\displaystyle \\ 
 \frac{\sin x}{1-\cos x} + \frac{\sin x}{1+\cos x} = \\ \\ 
 =\frac{\sin x(1+\cos x)}{(1-\cos x)(1+\cos x)} + \frac{\sin x(1-\cos x)}{(1+\cos x)(1-\cos x)} = \\ \\ 
 =\frac{\sin x+\sin x\cos x}{1-\cos^2x} + \frac{\sin x-\sin x\cos x}{1-\cos^2x} = \\ \\ 
 =\frac{\sin x+\sin x\cos x + \sin x-\sin x\cos x}{1-\cos^2x} = \\ \\ 
=\frac{2\sin x }{\sin^2x} = \frac{2 }{\sin x} =2 \times \frac{1 }{\sin x} = 2 \times \csc x = \boxed{2\csc x }$
