Answer:

x = 18

y = 45

Step-by-step explanation:

1. First off, we know that the angle (4x-7) degrees and (6x +7) are supplementary angles because of the corresponding angles theorem. So we do: (4x-7) + (6x+7) = 180 which should get you x=18.

2. Now that you know the value of x, finding y should be pretty easy. Plug in x for (6x + 7) and you should get 115 degrees.

3. We know that the angle with (6x +7) measurement is a vertical angle to (3y-20), so we can do 3y -20 = 115.

4. find the value of y, which should be 45

Answer:

x= 18

y =45

Step-by-step explanation:

first these two angles are supplementary and add up to 180 degrees:

(6x+7) + (4x-7) = 180

find x:

10x = 180

x = 18

substitute x = 18 for the angle (6x+7)

now we know what 6x +7 =

6 (18) + 7 = 115

since angle 3y-20 = 115, solve for y

3y = 135

y = 45

Answer: Correct critical value = 2.2622

Step-by-step explanation:

Confidence interval for population mean when population standard deviation is unknown:

$\overline{x}\pm t_{\alpha/2}\dfrac{s}{\sqrt{n}}$ , where $\overline{x}$ = sample mean, n= sample size, s= sample standard deviation, $t_{\alpha/2}$ = two-tailed t value.

As per given: n= 10

degree of freedom : df = n-1=9

$\overline{x}=242.6\\\\s=73.33\\\\\alpha=5\%=0.05$

Critical t-value : $t_{\alpha/2,df}=t_{0.05/2,9}=t_{0.025,9}=2.2622$

So, the 95 percent confidence interval estimate for the mean :

$242.6\pm (2.2622)\dfrac{73.33}{\sqrt{10}}\\\\=242.6\pm (2.2622)(23.19)\\\\\approx242.6\pm52.46\\\\=(242.6-52.46,\ 242.6+52.46)\\\\=(190.14,\ 295.06)$

The 95 percent confidence interval estimate for the mean:(190.14, 295.06)

0 A pigeon can fly at a speed of 84 kilometers per hour. How long does it take the pigeon to fly 7 kilometers

QveST [7]

The miles per hour is 84 kilometers per 60 minutes (7:5 ratio) so if we take seven kilometers times the ratio 5/7 we get 5 minutes

two years of local internet service cost $685 including the installation fee of $85 what is the monthly fee?

zimovet [89]

2 years is the same as 24 months, so the equation would be:
685 = 24x + 85, where x is the monthly fee.
600 = 24x
600/24 = x
x = 25
The monthly fee is $25.
