Answer:

i maybe wrong

Step-by-step explanation:

I think you take the formula (x+3, y-4) and u replace it with the P and Q points

so (2+3)=5

and (4-4)=0

and the same with the Q point

so its -3 + 3 = 0

and 2-4 = -2

so now u have

P' = ( 5,0) and Q'= (0,-2)

now the slope for that is also 2/5

Find the measurement of angle A

yaroslaw [1]

Answer:

The value of A is 20

Step-by-step explanation:

To find the answer, note that all triangles have a interior degree measurement of 180. Set the sum of the angles equal to 180.

71x - 1 + 20x + 90 = 180

91x + 89 = 180

91x = 91

x = 1

Now we can use this in the A angle to find the value.

A = 20x

A = 20(1)

A = 20

Refer to the accompanying TI-83/84 Plus calculator display of a 95% confidence interval. The sample display results from using

Darina [25.2K]

Answer:

[22.57 ± 2.776]

Step-by-step explanation:

Hello!

You have the 95% Confidence Z-interval (21.182;23.958), the mean X[bar]= 22.57 and the sample size n=25.

The formula for the Z interval is

[X[bar] ± $Z_{1-\alpha /2} *( \frac{Sigma}{\sqrt{n} } )$ ]

The value of Z comes from tha standard normal table:

$Z_{1-\alpha /2} = Z_{0.975}= 1.96$

The semiamplitude (d) or margin of error (E) of the interval is:

E or d= (Upperbond- Lowerbond)/2 = (23.958-21.182)/2 = 2.776

[X[bar] ± E]

[22.57 ± 2.776]

I hope it helps!
