Answer 1

Answer:

Step-by-step explanation:

Hello There!

complementary angles add up to equal 90

So to find the measure of angle 2 we subtract the given angle (33) from 90

90-33=57 so the measure of angle 2 = 57

Answer 2

Answer: 57°

Complementary Angles add up to 90°

Since we already have 33°, we need to find the other half.

90 - 33 = 57

It'll be 57°

You are the manager of a restaurant that delivers pizza to college dormitory rooms. You have just changed your delivery process in an effort to reduce the mean time between the order and completion of delivery from the current 21 minutes. A sample of 36 orders using the new delivery process yields a sample mean of 22.4 minutes and a sample standard deviation of 6 minutes.
A.) Please compute the test statistic. Please round to four decimal places.
B.) Please determine the p-value. Please round to four decimal places.
C.) Using a 0.05 level of significance, please provide the critical value for the appropriate test. Please round to four decimal places.
D.) Using a 0.05 level of significance, is there evidence that the population mean delivery time has been reduced below the previous population mean value of 25 minutes?

Answers

Answer:

1.4000 ;

0.0807 ;

1.69 ;

Fail to reject the Null

Step-by-step explanation:

Given :

μ = 21 minutes

x = 22.4 minutes

Sample size, n = 36

Standard deviation, s = 6

H0: μ ≥ 21

H1: μ < 21

Test statistic : (x - μ) ÷ s/sqrt(n)

Test statistic : (22.4 - 21) ÷ 6/sqrt(36)

Test statistic : 1.4 ÷ 1

Test statistic = 1.4000

Pvalue : Using the Test statistic value at α = 0.05 ; One - tail test = 0.0807

The t critical value using a critical value calculator ; DF = (n - 1) = 36 - 1 = 35 ; α = 0.05 = 1.69

Decision region :

Reject H0 if

|Test statistic| > |critical value|

1.4 < 1.69

Hence, we fail to reject H0

There isn't enough evidence they delivery time has been reduced below previous mean

Answer:

Octagon:

Sum = 1080

One interior angle = 135

14-gon:

Sum = 2160

One interior angle = 154.286

20-gon:

Sum = 3240

One interior angle = 162

Step-by-step explanation:

Sum of angles in a polygon -> sum of angles = (n – 2)180°

one interior angle = sum of angles/n

n = number of sides

one interior angle = sum of angles/n

Octagon:

Sum = 1080

One interior angle = 135

14-gon:

Sum = 2160

One interior angle = 154.286

20-gon:

Sum = 3240

One interior angle = 162

Answers

Answer:

Let x = the length

Let P = the perimeter of the first pool

48 = (1/3)P

144 feet = P

P = 2l + 2w

144 = 2x + 2(24)

144 = 2x + 48

96 = 2x

48 feet = x

Find the measure of the supplement of a
16° angle.

Answers

Answer:

164

Step-by-step explanation:

Hey There!

If they are supplementary angles then they will add up to equal 180

So given one of the angles (16) we subtract that from 180 to find the value of the missing angle

180-16=164

Your answer is 164

how do i solve this and what is the answer?

Answers

Answer:

I totally get why you are asking , how do I solve this. there is so much implied about this

Step-by-step explanation:

1st you have to recognize that ∠ACB ( in my drawing ) has that same angle as the arc from A to B , so that's implied. next you have to recognize that the triangle formed by ACB with the 124 degree angle at C is an isosceles and therefore has identical angles at A and B so that's 180 = 124 + 2A , so A = 28° and so does B , then , b/c we know that small angle... you also have to know, that the line AC is perpendicular to AD. that they from a right angle and there for... you now know , that ∠BAD is the other part of that 90 or 90= 28 + ∠BAD so ∠BAD = 62°

I went through that kinda fast, there was several "leaps" of using logic to get to the correct answer , using things you know from prior understanding about angles , circles and geometry, you are putting all of the parts together here. :/ kinda daunting in some ways.

subtract and write the difference in simplest form 12 5/8 - 7 1/3

Answers

Answer:

5 7/24

Step-by-step explanation:

Given the following mathematical expression;

12 5/8 - 7 1/3

First of all, we would subtract the whole numbers;

12 5/8 - 7 1/3 = (12 - 7) 5/8 - 1/3

12 5/8 - 7 1/3 = 5 [5/8 - 1/3]

Next, we subtract the fractions from each other;

5/8 - 1/3

Lowest common multiple (lcm) = 24

5/8 - 1/3 = (15 - 8)/24

5/8 - 1/3 = 7/24

Combining the two parts, we have;

12 5/8 - 7 1/3 = 5 7/24

PLEASE HELP!!!!!!!!!!! A clown has two performances today, in cities A and B, which are 240 km apart. The clown drives from City A to City B at a certain speed and performs. On his way back to City A, he drives half the distance at the same speed as before, but then increases his speed by 10 km/h to be on time for his performance in City A. Thus, the drive from B to A takes 2/5 of an hour less than the drive from A to B. At what speed does the clown drive from A to B?

Answers

Answer: 50 km/hr

240 = rt

120 = rt1

120 = (r+10)t2

t1 + t2 = t - 2/5 ==> t2 = 1/2 t - 2/5

So you get

240 = rt

120 = (r + 10)(1/2 t - 2/5)

Solve the system
