Answer:

  17.  C 60°

  18.  D 121°

Step-by-step explanation:

The external angle is half the difference of the intercepted arcs.

17. (161° -41°)/2 = 60°

__

18. (? -59°)/2 = 31°

  ? = 59° +2(31°) = 121°

External angle∠C of the given circle is 60°

The angle subtended by the arc VS  is 121°

External angle is half of the difference between angles subtended by arcs.

So in problem 17,

∠C = (161°-41°)/2 = 60°

In problem 18,

We got the external angle = 59°

Let us take the angle subtended by arc = x

so,

(x-59°)/2 = 31°

x = 121°

Therefore, External angle∠C of the given circle is 60°

The angle subtended by the arc VS  is 121°

Answer:

we will call the two angles a and b

a = 105

b = 75

Step-by-step explanation:

Supplementary means the two angles add up to 180 degrees.  Now this turns into a system of equations problem.  let's call the two angles a and b.

Lets say angle a is 45 degrees less than twice the other angle.  that means a = 2b - 45.  The first part told us a + b = 180

a + b = 180

a = 2b - 45

Now this is actually super easy to do.  Normally you would have to do algebra to one of the two equations so there is one variable by itself.  the second equation already has that.

now look at the other equation.  instead of a though make a = 2b - 45

a + b = 180

2b - 45 + b = 180

Now use algebra to solve for b

2b - 45 + b = 180

b = 75

Now, go back to the first two equations.  put 75 in for b for either one of them and you will get the answer to a.

a + 75 = 180

a = 105

or

a = 2*75 - 45

a = 105

Now we can check.  a=105 and b = 75

do both add up to 180?  yep.  is a 45 less than twice b?  or using numbers, is 105 45 less than twice 75?  well twice 75 is 150.  and 105 is 45 less than that, so yep!

Let me know if there was anything you didn't get.  Also you could totally have started with the other equation first and got a = 180 - b or b = 180 - a and gotten the same answer.

Answer:

-9<x≤2

Step-by-step explanation:

The domain is the x values

If we look at the line, we see a closed circle when x=2, so x is less than or equal to 2

The other circle is open and is at -9, so x is greater than -9

-9<x≤2

Answer: $8.28

Step-by-step explanation: 3 dozens are 36 cookies. The first 16, $0.28 each will be $4.48. The rest will cost $0.19 each so $0.19 x 20 = $3.80

$4.48 + $3.80 =

Answer:$8.28

Step-by-step explanation

Multiply 16x0.28 you will get $4.48 then

you Multiply 20x0.19 you get 3.8 also known as 3.80 you add

3.80+4.48+$8.28

Answer:

3 pairs of socks

Step-by-step explanation:

2 shirts *12per shirt = $24 spent so far

$39 - $24 dollars spent so far = $15 dollars left

$15 dollars left/$5 per pair of socks = 3 pairs of socks.

An equation is formed of two equal expressions. The total number of socks that Rebecca bought is 3.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of pairs of socks that Rebecca bought be represented by x.

Given that Rebecca buys some socks that cost $5 per pair and 2 t-shirts that cost $12 each. Also, the total purchase value is $39. Therefore, we can write the equation as,

Purchase value of socks + Purchase value of t-shirts = Total purchase value

($5 × x) + ($12 × 2) = $39

5x + 24 = 39

5x = 39 - 24

5x = 15

x = 15/5

x = 3

Hence, the total number of socks that Rebecca bought is 3.

C.)

Right tailed test

D.)

If Pvalue is less than or equal to α ; we reject the Null

Step-by-step explanation:

The significance level , α = 0.01

The Pvalue = 0.0264

The decision region :

Reject the null if :

Pvalue < α

0.0264 > 0.01

Since Pvalue is greater than α ; then, we fail to reject the Null ;

Then there is no significant evidence that the mean graduate age is more Than 31.

H0: μ ≥ 16

H1: μ < 16

Null Fluid contains 16

Alternative hypothesis, fluid contains less than 16

C.)

Null hypothesis :

The transformations which is NOT preserve the size and the shape of the figure is dilate by a scale factor of 4 (B) and dilate by a scale factor of 1 (C).

Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.

When a figure is dilated, the size of the original figure is changed.

A figure is graphed in the coordinate plane. Let's check all the option for the transformation of original figure.

Hence, the transformations which is NOT preserve the size and the shape of the figure is dilate by a scale factor of 4 (B) and dilate by a scale factor of 1 (C).

Answer:

Step-by-step explanation:

1. The empirical rule tells you 68% of the distribution is within 1 standard deviation of the mean. The mean is 50 and the standard deviation is 0.2, so this means 68% of the bags weigh between 49.8 and 50.2 lb.

__

2. The other 32% is evenly split above and below the central part of the distribution. That is, about 16% of the bags will weigh less than 49.8 lb.

__

3. The percentage is independent of the size of the group. The empirical rule tells you 95% lie within 2 standard deviations of the mean. The other 5% will be evenly split between those weighing more than 50.4 and those weighing less than 49.6 lb. About 2.5% of the bags will weigh more than 50.4 lb.

_____

Additional comment

It is useful to remember the empirical rule numbers, 68%, 95%, 99.7% for the portion of the distribution between ±1, 2, 3 standard deviations of the mean. They are useful for answering questions like this one. (They are only approximations, so if more accuracy is needed, a table or app should be used to find the accurate value.)
