Answer:

y = 94

Step-by-step explanation:

Linear Pair:

The two adjacent angles whose non common arms form a straight line is called linear pair. They add up to 180

2x + 36 = 180 {linear pair}

2x = 180 - 36

2x = 144

Sum of all angles of a n-sided polygon = (n-2)*180

= ( 6-2)*180

= 4 * 180

= 720

y + 144 + 111 + 105 + 165 + 101 = 720

y + 626 = 720

y = 720 - 626

$\sf \boxed{y = 94^ \circ}$

Answer:

94°

Step-by-step explanation:

2x + 36 = 180 (angles on a straight line)

2x = 180 - 36

2x = 144

2x = 144°

Sum of all angles of a n-sided polygon = (n-2)×180 = ( 6-2)×180

= 4 × 180

= 720

y + 144 + 111 + 105 + 165 + 101 = 720

y + 626 = 720

y = 720 - 626

y=94 °

What is the radius of a circle with an area of 9671.99 cm²? Use 3.14 for pi.

Tcecarenko [31]

Answer:

55.5000143456...

Step-by-step explanation:

Use the formula for the area of a circle and solve for r:

$A=\pi r^2\\9671.99=3.14r^2\\3080.25159236...=r^2\\55.5000143456...=r$

In recent years the mean number of miles driven per year by residents of a particular state was 11,568. A researcher wishes to t

aleksandrvk [35]

Answer:

The degrees of freedom are given by:

$df =n-1= 62 -1=61$

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be $t_{\alpha/2}= \pm 2.00$

And the rejection region would be $|t_{calc}| >2.00$

Step-by-step explanation:

Data given and notation

$\bar X=10822$ represent the sample mean

$s=1741$ represent the sample standard deviation

$n=62$ sample size

$\mu_o =11568$ represent the value that we want to test

$\alpha=0.05$ represent the significance level for the hypothesis test.

z would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the true mean differs from 11568, the system of hypothesis would be:

Null hypothesis: $\mu =11568$

Alternative hypothesis: $\mu \neq 11568$

The degrees of freedom are given by:

$df =n-1= 62 -1=61$

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be $t_{\alpha/2}= \pm 2.00$

And the rejection region would be $|t_{calc}| >2.00$

Your computer-supply store sells two types of inkjet printers. The first, type A, costs $237 and you make a $22 profit on each o

Vera_Pavlovna [14]

The minimum cost option can be obtained simply by multiplying the number of ordered printers by the cost of one printer and adding the costs of both types of printers. Considering the options:
69 x 237 + 51 x 122 = 22,575
40 x 237 + 80 x 122 = 19,240
51 x 237 + 69 x 122 = 20,505
80 x 237 + 40 x 122 = 23,840
Therefore, the lowest cost option is to buy 40 of printer A and 80 of printer B

The equation, x + 2y ≤ 1600 is satisfied only by options:
x = 400; y = 600
x = 1600
Substituting these into the profit equation:
14(400) + 22(600) - 900 = 17,900
14(1600) + 22(0) - 900 = 21,500
Therefore, the option (1,600 , 0) will produce greatest profit.

True false to find the midpoint of a segment, first mark a point not on the segment and then fold the paper so that the point yo

SIZIF [17.4K]

That is not true. To find the midpoint of a line, you must add the values of x’s together and divide by 2 and then add the values of y together and divide by 2. The formula is (x1+x2/2 , y1+y2/2)
