I did this before and it’s b

in his first four years of coaching football, Coach Delgato's team won 5 games the first year, 10 games the second year, 8 games the third year, and 7 games the fourth year. How many games does the team need to win the fifth year to have an average of 8 wins per year?

Answers

he will need to wins 14 games

The team needs to win 10 games in the fifth year to have an average of 8 wins per year over the five-year period.

To find out how many games the team needs to win in the fifth year to have an average of 8 wins per year over the five-year period, we can use the following equation:

(5 + 10 + 8 + 7 + x) / 5 = 8

Here, x represents the number of games the team needs to win in the fifth year.

To solve for x, we can simplify the equation:

(30 + x) / 5 = 8

Now, we can cross-multiply:

30 + x = 40

Subtracting 30 from both sides of the equation, we get:

x = 10

Therefore, the team needs to win 10 games in the fifth year to have an average of 8 wins per year over the five-year period.

Need help finding measurements on a rhombus

Answers

All of the measurements are the same because a rhombus is just a tilted square:
All sides are 4cm
Hope it helps ;)

Answer:

5. D 6. B 7. C

Step-by-step explanation:

All side lengths of a rhombus are the same therefore the length of WZ must be 4cm.

The sum of all the angles in a rhombus add up to 360 degrees, since we already have 2 100 degrees( opposite interior angles are the same) then the rest must be 80 degrees angles.

\(105+3x=180 \\ \\ 3x=75 \\ \\ x=25\)

Answer:

The answer is 25 degrees

Step-by-step explanation:

If you subtract 180 - 105 then you get 75.
Then you divide it by 3.
One circle is 360 degrees thus half of it is 180.
If you know one angle is 105 degrees then subtract it from 180.
If the number is 3x then you have to divide it by 3 to get x alone.

Answers

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

A spinner is divided into five sections, labeled A, B, C, D, and E. Devon spins the spinner 50 times and records the results in the table.

Based on the table above, make a prediction for 200 trials.

Answers

Answer:

Prediction for 200 trials: A- 40 times, B- 56 times, C- 48 times, D- 32 times, E- 24 times

Step-by-step explanation:

A=10/50=1/5 (then multiply by 200)

B=14/50=7/25 (then multiply by 200)

C=12/50=6/25 (then multiply by 200)

D=8/50=4/25 (then multiply by 200)

E=6/50=3/25 (then multiply by 200)

To make a prediction for 200 trials, we can look at the proportion of each section in the 50 trials and assume that the same proportion will hold for 200 trials.

In the 50 trials, we see that section A occurred 9 times out of 50, or 18% of the time. Similarly, section B occurred 10 times out of 50, or 20% of the time. Section C occurred 15 times out of 50, or 30% of the time. Section D occurred 8 times out of 50, or 16% of the time. Finally, section E occurred 8 times out of 50, or 16% of the time.

Assuming that the same proportion holds for 200 trials, we can predict the number of occurrences for each section as follows:

- A: 0.18 x 200 = 36 occurrences
- B: 0.20 x 200 = 40 occurrences
- C: 0.30 x 200 = 60 occurrences
- D: 0.16 x 200 = 32 occurrences
- E: 0.16 x 200 = 32 occurrences

Therefore, based on the table above, we can predict that in 200 trials, section C will occur the most frequently (60 times), followed by section B (40 times), section A (36 times), and sections D and E equally (32 times each). It's important to note that this is just a prediction based on the observed data, and the actual results may vary due to chance.

If the relationships below are given in the form (input, output), which pairing always describes a function? (a person’s age in years, that same person’s height in inches) (a person’s weight in pounds, that same person’s height in inches) (a person’s height in centimeters, that same person’s height in inches) (a person’s telephone number, that same person’s height in inches)

Answers

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

How did we arrive at this assertion?

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there

Answers

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Which graph represents the inequality 2.5 is less than the product of −0.5 and a number?

Answers

Answer: The mathematical statement is given as

"2.5 greater than the product of -0.5 and a number"

Product means times

So, we have the following representation

"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 greater than -0.5 * a number

Let the number be x

So, we have

"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 greater than -0.5x

Greater than is represented by >

So, we have

"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 > -0.5x

Next, we plot the graph of the inequality expression
