Answer:

1) 8

2) 20

3) 10.8

4) -25

5) 7

6) 3/2

Step-by-step explanation:

The graph that represents the solutions to the system of equations is Option A.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

3x - y = -1 _____(1)

x + y = 5 ______(2)

From (1),

3x + 1 = y

From (2),

y = 5 - x

The point of intersection is (1, 4).

3x + 1 = 5 - x

4x = 4

x = 1

Putting x = 1 in (2).

1 + y = 5

y = 5 - 1

y = 4

The graph on option A has the point of intersection at (1, 4).

Thus,

The graph that represents the solutions to the system of equations is Option A.

The actual rainfall for last June is 0.5

1.14 is the amount of rain that fell last July.

2.43 is how much rain would have to fall for August to match the three months average

0.86 is the departure from the average in August

Step-by-step explanation:

1. 0.67-0.17 = 0.5

2. 1.5-0.36 = 1.14

Step-by-step explanation:

a) 0.5​ inches. The difference between the average rainfall and the actual rainfall for last June is 0.67-0.17=0.50​ inches.

b) 1.14​ inches. Because the departure from the average was negative, the actual rainfall was 0.36​ inches less than the average rainfall. Thus, 1.5-0.36=1.14​ inches was the actual rainfall last July.

c) 2.43​ inches. The average rainfall for these three months is 0.67+1.5+1.57=3.74​ inches. Last June it rained 0.17​ inches and last July it rained 1.14 inches. So, it would need to have rained 3.74-0.17-1.14=2.43​ inches last August so that the total amount of rain equaled the average rainfall for these three months.  

0.86​ inches. The departure from the average would then be 0.86​ inches since 2.43-1.57=0.86​​ inches.

Answer:

The answer is A

Step-by-step explanation:

Answer:

Inflation is caused by the increase in prices of goods, and as prices of goods rise, the value of money itself would decrease. By saving money in a savings account with interest that might be equal or more than the level of inflation, your money would increase, which protects you from the devaluation of the savings you hold and the rising prices of goods.

Answer is C: Both of the means are correct, but the reasoning is incorrect.

Step-by-step explanation:

Check picture because Im bad at explaining

Hope it helps :3

Both of the means are correct, but the reasoning is incorrect explains Jacob's error. Thus option C is correct.

There seem to be various mean types in algebra, particularly in statistics. Each average helps to summarize a certain sample of statistics, frequently to help figure out the general significance of a specific data set. The average of a group of variables is referred to as the mean in both statistics as well as mathematics.

Jacob discovered that Team A's maximum elevation is 71 and Team B's average height is 72. He thinks that since Team B's mean is higher, its mean absolute deviation must likewise be higher. There the sum of the data is taken and not the value decides what will be the desired mean.

Therefore, option C is the correct option.

Understanding the Absolute Value.

First, know what the absolute value is.

The absolute value is the value that determines how far the value is from 0.

For example, The absolute value of -5 is far from 0 5 units. Therefore the absolute value of -5 equals 5.

Basic Absolute Value Defines

| a | = a

- | a | = -a

| - a | = a

Back to the question. To evaluate those expressions, we use the defines of absolute value.

|-16| = 16

|-1| = 1

16-(1)

Then remove the brackets. 16 - 1 = 15

Therefore, the answer is 15.

The answer above is when being subtracted and evaluated from both 16-1

Evaluating for each expressions would be

|-16| = 16

-|-1| = -1

Answer:

Not necessarily, because this wasn't an experiment.

Step-by-step explanation:

Making conclusion based on the result of the survey about the happiness of employees due to the fact that they work in a digital workplace is inaccurate.

Statistical tests may not be enough to make generalization about the entire population due to the presence of a possible confounding or third variable unless established using scientific evidence.

Therefore, the lack of scientific evidence means that concluding that working in a digital workplace causes employee happiness is inaccurate.

Answer:

Your question was a bit confusing so I found another related question. You can reference it with your own details.

A vendor bought 10 dozen eggs at the rate of Rs 22 per dozen. Six of the eggs were rotten. He sold the remaining eggs at the rate of Rs 2.50 per egg . Find his profit or loss

Vendor bought 10 dozen eggs which means the vendor bought:

= 10 * 12 eggs

= 120 eggs

6 were rotten and he sold the rest for Rs. 2.50 per egg.

= (120 - 6) * 2.5

= Rs. 285

The amount he spent on the eggs was:

= 10 dozen * 22

= Rs. 220

Profit = 285 - 220

= Rs. 65

Concept: Statistical Modeling

4 divided by 3C

If C equals 6, then the equation now looks like 4 divided by 3(6).

3 x 6 = 18.

4 divided by 18 is .22 repeating.

This may be wrong. Check with another answer.

Answer: 2/9

Work: So, you are going to get the equation after plugging in the number 4/3(6), after simplifying even more, you get 4/18. Then you simplify again and divide both sides (Numerator and denominator) and you get 2/9.
