Can someone help me and give an explanation

Two triangles: left triangle with y degrees and 40 degrees and right triangle with x degrees.

  • 40 degrees from the left triangle, when adding with the unknown angle of the right triangle, is equal to 180 degrees.
  • Adding left triangle's (third) undetermined angle and x degrees angle (the other same angle), is equal to 90 degrees.
  • The right triangle is an isosceles triangle, meaning two equal angles, and one of them is x degrees. Thus, the other same angle is also x degrees.

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

1) Subtract 180 - 40 = 140 degrees. 140 degrees is the unknown angle of right triangle.

2) 140 + x + x = 180 (equation)

  • 140 + 2x = 180
  • 2x = 180 - 140
  • 2x = 40
  • x degrees = 20 degrees

ANSWER: x = 20 DEGREES

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

1) With knowledge of x degrees being 20 degrees, the other same angle is 20 degrees, too.

2) Subtract 90 - 20 = 70 degrees. 70 degrees is the (third) undetermined angle

of left triangle.

2) 70 + 40 + y = 180

  • 110 + y = 180
  • y = 180 - 110
  • y = 70 degrees

ANSWER: y = 70 DEGREES

The circumference of a circle is 31 in.<br> What is the area of the circle?
garik1379 [7]

Answer: 76.35in²

Step-by-step explanation:

Circumference of a circle = 2πr or πd , while area is πr².

To find the area we must first of all find the radius if the circle using any of the formula above.we then equate 31 to 2πr and then solve for r.

31 = 2πr , where π = 3.142 or 22/7

r = 31/2 x 3.142

= 31 /6.284

= 4.93in

To find the area, substitute for r in the formula above,

Area = πr²

= 3.142 x 4.93²

= 3.142 x 24.30

= 76.35in².

If we are testing for the difference between the means of 2 independent populations presuming equal variances with samples of n1
Musya8 [376]

Answer:

Null hypothesis: \mu_1= \mu_2

Alternative hypothesis:\mu_1 =\neq \mu_2

And for this case we assume that we have equal variances so that means:

\sigma =\sigma_1 =\sigma_2

For this case the degrees of freedom are given by:

df= n_1 +n_2 -2

And replacing we got:

df= 20+20 -2= 38

And the best answer would be:

a. 38

Step-by-step explanation:

For this problem we want to test the following:

Null hypothesis: \mu_1= \mu_2

Alternative hypothesis:\mu_1 =\neq \mu_2

And for this case we assume that we have equal variances so that means:

\sigma =\sigma_1 =\sigma_2

For this case the degrees of freedom are given by:

df= n_1 +n_2 -2

And replacing we got:

df= 20+20 -2= 38

And the best answer would be:

a. 38
