5) –2x – 9y=-25<br> -4x – 9y=-23

notka56 [123]

Answer:

(-1,3)

Step-by-step explanation:

–2x – 9y=-25

-4x – 9y=-23

Multiply the second equation by -1

4x + 9y=23

Add this to the first equation

–2x – 9y=-25

4x + 9y= 23

-----------------------

2x = -2

Divide each side by 2

2x/2 = -2/2

x = -1

Now we need to find y

4x+9y = 23

4(-1) +9y = 23

-4 +9y = 23

Add 4 to each sdie

-4+4 +9y = 23+4

9y = 27

Divide each side by 9

9y/9 = 27/9

y =3

Out of 1,500 licensed drivers, 900 admitted that they do not like to drive at night. What is the 92% confidence interval for the

Lynna [10]

The confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.

<h3><u>Confidence interval</u></h3>

To determine what is the 92% confidence interval for the population mean of drivers that do not like driving at night, the following calculation must be performed:

1500 = 100
900 =X
900 x 100 / 1500 = X
60 = X
60 x 0.92 = 55.2
60 x 1.08 = 64.8

Therefore, the confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.

Aliun [14]

Question:

A prism with a base area of 8 cm² and a height of 6 cm is dilated by a factor of 5/4 .

What is the volume of the dilated prism?

Enter your answer, as a decimal, in the box.

Answer:

The volume of the dilated prism is $93.75 \ {cm}^{3}$

Explanation:

A prism with a base area of 8 cm² and a height of 6 cm

The volume of the prism can be determined by the formula, $V=Bh$

Volume of the prism is given by

$V=Bh$

$V=(8)(6)$

$V=46\ cm^3$

Thus, the volume of the prism is $46 \ {cm}^{3}$

It is also given that the volume of the dilated prism is dilated by a factor of $\frac{5}{4}$

Hence, the new volume is given by

$Volume = 48(\frac{5}{4} )^3$

$=48(\frac{125}{64} )$

$=48(1.953125)$

$=93.75 \ {cm}^{3}$

Thus, the volume of the dilated prism is $93.75 \ {cm}^{3}$
