Answer:

y = 8

Step-by-step explanation:

Step 1: Write out equation

13 + 3y = 37

Step 2: Subtract 13 on both sides

3y = 24

Step 3: Divide both sides by 3

y = 8

Answer:

y=8

Step-by-step explanation:

37-13 = 24

The table showing the data is missing, so i have attached it.

Answer:

0.8

Step-by-step explanation:

We want to find the probability that a randomly selected employee at this government agency prefers a four day work week or is under 30.

Now, we are told that the government agency has 6000 employees. Also, from the attached table, we see that the  number of people who prefer a 4 day work week are a total of:

600 + 1200 + 2100 = 3900

Thus, probability of people who prefer a 4 day work week = 3900/6000 = 39/60

Also, we see that total number of people aged under 30 = 600 + 300 = 900

Thus, probability of people aged under 30 is;

900/6000 = 3/20

Thus;

probability that a randomly selected employee at this government agency prefers a four day work week or is under 30 = 39/60 + 3/20 = 48/60 = 4/5 = 0.8

Answer:

55

Step-by-step explanation:

First you need to know how much is 2/5 of 550 since that is how much she put in the jar. 2/5 * 550 = 220 and then you need to find a 1/4 of that since that is how much she takes from th jar for vecation. 1/4 * 220 = 55 which is the awnser

Interval notation of this problem.

Answer:

The possible number of CDs she could buy is 1, 2, and 3.

Step-by-step explanation:

First, you have to make an equation to solve to find the answer(s):

1.) 80 - (18 · 1) ≥ 20

80 - 18 · 1 ≥ 20

80 - 18 ≥ 20

62 ≥ 20

Since 62 ≥ 20 is always true, there are infinitely many solutions.

2.) 80 - (18 · 2) ≥ 20

80 - 18 · 2 ≥ 20

80 - 36 ≥ 20

44 ≥ 20

Since 44 ≥ 20 is always true, there are infinitely many solutions.

3.) 80 - (18 · 3) ≥ 20

80 - 18 · 3 ≥ 20

80 - 54 ≥ 20

26 ≥ 20

Since 26 ≥ 20 is always true, there are infinitely many solutions.

4.) 80 - (18 · 4) ≥ 20

80 - 18 · 4 ≥ 20

80 - 72 ≥ 20

8 ≥ 20

Since 8 ≥ 20 is false, there is no solution.

5.) 80 - (18 · 5) ≥ 20

80 - 18 · 5 ≥ 20

80 - 90 ≥ 20

- 10 ≥ 20

Since - 10 ≥ 20 is false, there is no solution.

An earthquake with an energy level  1  of has a magnitude of -3.2 .

Hello my Alpha.... bows down*

The curve representing the relationship includes the point  (1, -3.2).

The growth factor is 0.6666. An earthquake with an energy level of has a magnitude of – 3.2.

It is given that the magnitude of an earthquake depending on the energy .it produces can be modeled using the equation M = 0.6666 log x – 3.2.

It is required to find growth factor, point and magnitude.

The amount of energy released is represented as E and an earthquake release the magnitude represented by M which is given in the question. This magnitude is represented as equation using logarithm of the height of the wave that is the scale measured by seismograph.

Thus, The curve representing the relationship includes the point  (1, -3.2).

There is no rise over run therefore, there is no slope.

You have to have rise over run to be able to have a slope.

Answer:

400,000

Step-by-step explanation:

Step-by-step explanation:

AB = AC, so mark the two sides with single tick marks.

m∠ACD = 128°, so label the angle 128°.

∠ACB is supplementary to ∠ACD, so:

m∠ACB + m∠ACD = 180°

m∠ACB + 128° = 180°

m∠ACB = 52°

ΔABC is an isosceles triangle, so m∠B = m∠ACB.

m∠B = m∠ACB

m∠B = 52°

Angles of a triangle add up to 180°, so:

m∠A + m∠B + m∠ACB = 180°

m∠A + 52° + 52° = 180°

m∠A = 76°

Answer: $292.30

Step-by-step explanation:

28x + 44y = 964.40

21x + 33y = 723.30

Let's multiply the first equation by 4 and the second by -4

84x + 176y = 3857.6

-84x - 132y = -2893.2

Add the equations together.

0 + 44y = 964.4

Simplify

44y = 964.4

Divide both sides by 44

y = 964.4/44

Since we have the value of y, let's plug 964.4/44 into y for the first equation.

28x + 44(964.4/44) = 964.40

Simplify the left side

28x + 964.4 = 964.4

Subtract 964.4 from both sides

28x = 0

Divide both sides by 0

x = 0

In conclusion,

y = 964.4/44

x = 0

Answers:

Check out the diagram below

===================================================

Explanation:

When reflecting over horizontal lines like this, the x coordinate stays the same as the original point. Only the y coordinate changes.

To find what the y coordinate changes to, we need to measure the vertical distance from the point to the line. Point S has a y coordinate of y = -5 and the vertical distance to the line of reflection (y = 1) is |-5-1| = |-6| = 6 units. So we move 6 units up to go from point S to the line of reflection. We must move another 6 units to get to the location for S' where its reflected point would end up, which has y coordinate y = 7.

The same applies for the other points as well. Point T also goes up 6 units to get to y = 1, then it moves another 6 units to get to y = 7

Points V and U only move up 1 unit to get to the green dotted line of reflection. So they'll move only one additional unit to have their reflected points have y coordinates of y = 2.

The diagram hopefully visually summarizes everything discussed so far. The mirroring line cuts the distance from S to S' in half, same for T to T', and so on.

You know that lines PQ and RS are parallel and line XY is a transverse line. This means that XMP and QMN are equal because they are vertical angles. Now set the equations equal to each other because they are.

Answer:

i think its p ≤ 85 or p ≥ 125

Step-by-step explanation:

p can be 85 and higher but can be passed 125 but it can be 125 which makes the equality signs have the line under them meaning less than or equal to, and could also mean greater than or equal to.

The  inequality that represents P the scores for students who are eligible for tutoring or extension activities ​is p ≤ 85 or p ≥ 125.

Average is the mean of the data set obtained by summing all the values of the data set and then dividing it by the number of data in the set.

The average score is 105

The score required for tutoring is at least 20 points higher than average

The score required for extension activities is at least 20 points lower than average

P is the scores for students who are eligible for tutoring or extension activities ​

Then p ≤ 105 -20 = p ≤ 85

p ≥ 105+20 = p ≥125

p ≤ 85 or p ≥ 125
