Answer:

.85%

Step-by-step explanation:

You add up all the students who have an A whether they are male or female. 3 + 17 = 20. You have 17 males right? Divide 17 by 20 to get .85

Answer:

35.8°

144.2°

Step-by-step explanation:

Definition of Supplementary Angles: They add up to 180°

Step 1: Set up equation

3x + 12x + 1 = 180

Step 2: Solve

15x + 1 = 180

15x = 179

x = 11.93

Step 3: Find angles

∠1 = 3x

m∠1 = 3(11.93) = 35.8°

∠2 = 12x + 1

m∠2 = 12(11.93) + 1 = 144.2°

The distributive property is used when you have a value multiplied by 2 values separated by an operation.

For example, if you have x (y + z), then you would use the distributive property to get x (y + z) = xy + xz.

Answer:

Step-by-step explanation:

This problem seeks to tests our understanding of measurements and units

Kathy cannot compare the two measurements because the two units of measurement are not the same.

Now centimetres  is 10 times bigger than millimetres.

What Kathy can actually do is to convert from one unit to another, that is from centimetres to millimetres.

Since the units are not similar Kathy cannot compare them but she can convert from one to the other

Answer:

The correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].

Step-by-step explanation:

We know that the opposite of the opposite of a number, say 2, is the number itself.

That is:

Opposite of 2 is -2.

Then the opposite of -2 is:

- (-2) = 2

It is provided that:

Assume that both Justine and Meagan started with 0 score.

Justine plays first.

If Justine answered a question incorrectly, his score would be -7.

Then Meagan plays, and answers the question correctly.

So, Meagan got the opposite score.

The opposite of -7 will be [- (-7)].

Thus, the correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].

Answer:

x = -5

Step-by-step explanation:

4 + 2(x - 4)= -7(x + 7)

4 + 2x - 8 = -7x - 49

2x - 4 = -7x - 49

2x + 7x = -49 + 4

9x = -45

x = -45/9

x = -5

Answer: The whole equation is simplified down to -20.

Step-by-step explanation:

Here's how I got my answer:

Equation is 4p^2 + 7q^3

All you need to do is plug in the values they have given you. If you apply them, you get:

4 (-3)^2 + 7 (-2)^3

Which simplifies to:

4 (9) + 7 ( -8)

Simplify furthermore:

36 + (-56)

Which gives you:

-20

Answer:

R = P+C

Step-by-step explanation:

P = R-C

+C    +C

R = P+C

Step 1:

First, let's order the number from least to greatest.

A. -0.31

B. -0.33

C. -0.38

D. -0.29

We could see that A, B, and C's numbers are already from least to greatest, so all we have to do is to move -0.29 (D) up to the top, since -0.29 is the number with the lowest value.

C. -0.38

B. -0.33

A. -0.31

D. -0.29

Step 2:

Let's look at the four number lines. Remember that we already organized the numbers from least to greatest, so the order they go in on the number line is: C, B, A, and D. Since Line C and D Don't follow that rule, we know those are not our answers. Also on line B, C is on the left of -0.4, but C's value is less than -0.4, so B is wrong. We are left with line A.

Line A: C. -0.38, B. -0.33, A. -0.31, D. -0.29

Our answer: Line A

B: -0.3

Answer:

40 - x - x - x - 5.75  OR  40 - 3x - 5.75  OR  34.25 - 3x

Step-by-step explanation:

To find the amount of money Tim has left, we will simply write an expression that starts with the total he started with subtracting each expense.

$40

- $x

- $x

- $x

- $5.75

________________________

$40 - $x - $x - $x - $5.75

= $ (40 - 5.75) - 3(x)

= $ 34.25 - 3x

So you can choose one of three of these expressions:

(1) 40 - x - x - x - 5.75

(2) 40 - 3x - 5.75

(3) 34.25 - 3x

[tex]\sin(12\º) - \cos(78\º)[/tex]

Consider the cofunction identity:

[tex]$\boxed{\sin(\theta)=\cos \left(\frac{\pi}{2} - \theta \right)} $[/tex]

[tex]$\boxed{\sin(\theta)=\cos \left(90\º - \theta \right)} $[/tex]

[tex]\sin(12\º)=\cos(90\º - 12\º)=\cos(78\º)[/tex]

[tex]\therefore \cos(78\º) - \cos(78\º) = 0[/tex]

The value of Sin 12-cos 78 is 0

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given here: sin 12 - cos 78​ = Sin(90-12)-cos78 but we know sine of any angle = the cosine of any complementary angle

Thus we have Sin78-Cos78=0

Hence, The value of Sin 12-cos 78 is 0

What is a correct statement about distribution?

There no outliers

The distribution is symmetric

The center is around 80

The distribution is unimodal

The spread is from 57 to 89.

Answer: The distribution is unimodal.

Step-by-step explanation: Stem Plot is an unique way of writing numbers in a table. Each value is split into a "stem" (first digit or digits) and a "leaf" (usually the last digit).

For the swim team practice, we have:

57, 59, 61, 62, 63, 64, 76, 76, 125

Note that, although there the digits 8, 9, 10, and 11, there no "leaves" for them, so, the values are not part of the distribution.

Outlier is a value that lies outside most of other values. In the distribution there is the value 125 which is very much more than other values, i.e., it is an outlier, so, alternative "There no outliers" is false;

Ploting the values on a frequency graph, it shows a curve skewed to the right, i.e., deslocated to the right, then, it is not symmetric. Second alternative is false.

The center of the distribution is the middle value, which is 63, then, third statement is false.

The spread of this distribution is from 57 to 125, so fifth statement is incorrect.

An unimodal distribution is a distribution which has only one clear peak or most frequent value. At the swim team distribution, the value that appears more than once is 76, so the peak is at that value. The other values appears just once, so distribution has only one peak. Fourth statement is correct.

Answer:

Step-by-step explanation:

To construct an equilateral triangle so that segment AB is one of the sides of the triangle we will follow the following steps.

1). Set a distance equal to the segment AB in the compass and draw two arcs on the same side of AB.

2). Join the point of intersection of these arcs to A and B with the help of a straightedge.

3). Hence an equilateral triangle (with all equal sides) is constructed.

Answer:

x is the song. she has to pay 99 cents per song.

Answer:

First of all, you are going to add

5

x

to each side. This will give you a new equation of

8

x

=

16

. The reason you add 5 is because you want to get rid of the -5x on the right. When you add 5 it changes to 0x. Anything times 0 equals 0. The next step is to divide both sides by 8. The reason you divide is to get x alone. When you divide 8x by 8, you get 1x. 1 times anything equals what the other thing is. For example, 1 times 4 is 4. This will give you your answer of
