Answer:

90^{\circ}

Step-by-step explanation:

An angle is a figure obtained by two rays sharing a common vertex .

Here, a ray is a line with only one end point .

A line segment is a line which has two end points .

Vertex is a point where the two lines meet .

Two angles \alpha and \beta are said to be complementary if \alpha +\beta = 90^{\circ} .

{ For example if we take \alpha= 40^{\circ} then it's complement is \beta = 50^{\circ} as \alpha +\beta =40^{\circ}+50^{\circ}=90^{\circ} }

So, we can say if two angles are complementary then their sum is 90^{\circ} .

Option B. is correct .

Delvig [45]
The rate of change is it drops 3 degrees every hour.
my work :12-(3×6)=-6
9:00 = 12 degrees 10:00 = 9 degress. 11:00 = 6 degress. 12:00 = 3 degress 1:00 = 0 degress. 2:00 = -3 degress 3:00 = -6 degress

  • 18. B. 234 in²

Step-by-step explanation:

#17

<u>Total surface area is:</u>

  • A = 8(3*2 + 6*2) + 2(3*6) = 180 in²

Correct option is A

#18

<u>Total surface area is:</u>

  • A = 2(9*9) + 4(2*9) = 234 in²

Correct option is B

5. When looking at a map, a student realizes that Birmingham is nearly due west of Atlanta, and Nashville is nearly due north of
leonid [27]

Answer: 250 mi

Step-by-step explanation:

Here we can think in a triangle rectangle:

The distance from Birmingham to Atlanta is roughly 150 mi, and this is one of the cathetus.

And the distance from Birmingham to Nashville is roughly 200 mi, this is the other cathetus of the triangle.

Now, the distance from Atlanta to Nashville will be the hypotenuse of this triangle rectangle.

Now we can apply the Pythagorean's theorem:

A^2 + B^2 = H^2

Where A and B are the cathetus, and H is the hypotenuse:

Then:

H = √(A^2 + B^2)

H = √(150^2 + 200^2) mi = √(62,500) mi = 250 mi

Then the estimated distance from Atlanta to Nashville is 250 mi

Suppose that 35% of all voters voted for a recall. Find the mean of the sampling distribution of the proportion of the 3150 peop
Aloiza [94]

Answer:

0.35 is the mean of the sampling distribution of the proportion.

Step-by-step explanation:

We are given the following in the question:

Percentage of voters who voted for recall = 35%

p = 35\% = 0.35

Sample size, n = 3150

We have to find the mean of the sampling distribution.

Formula for mean of sampling distribution:

\mu = p

Putting values, we get,

\mu = 0.35

Thus, 0.35 is the mean of the sampling distribution of people sampled in an exit poll who voted for the recall.
