Answers

Answer 1

Answer:

7 Hours on Average

add up all the hours and you get 35

then divide 35 by the number of given hours which is 5

35/5 = 7

so the average amount of hours slept was 7

Answer 2

Answer:

Answer:

7 hours

Step-by-step explanation:

To find this average, add up the five data points given and divide your result by five (5):

(7 + 9 + 5 + 6 + 8) / 5 = 35 / 5 = 7

This group of students averaged 7 hours of sleep per night.

Answer:

Ola taxi charges a $8 flat rate in addition to $2 per mile. Paul has no more than $10 to spend on a ride.

Let x be the number of miles.

Then, we have inequality: $8x+2\leq 10$

Solve the inequality: $8x+2\leq 10$ .

Subtract 2 from both the sides:

$8x+2-2\leq 10-2$

Simplify:

$8x\leq 8$

Divide by 8 both sides we get;

$x\leq 1$

as shown in figure 1.

From the context of the problem :

we can say that Paul can travel 1 miles or less before reaching his limit of $10.

Answer:

A football team wants to by a football. The football costs $51. There are 11 members of the team. How much will each of the team members contribute to be able to purchase the football if they had $29 already.

Solution: Let the amount each team member contributes be x, then

11x + 29 ≥ 51

11x ≥ 51 - 29

11x ≥ 22

x ≥ 22/11

x ≥ 2

Please answer ASAP

Answers

Answer:

Step-by-step explanation:

The general form of the equation for a line is:

$y=mx+b$

where the number $m$ that accompanies the x is the slope of the line, and the number $b$ is called the y-intercept of the line.

In this case we have the equation:

$y=5x$

we can see that we don't have any number added, so in this line $b=0$ , and the number that accompanies the x is 5, so

$m=5$ which is the slope of the line

So the answer is 5.

The slope of the graph of [ Y = 5x ] is 5 .

79, 79, 91, 91, 91, 91, 98, 98, 118, 130, what is the mean median and mode?

Answers

To get the mean you add the numbers and divide by how many numbers there are and then you would get: 784 divided by 10 which would be 78.4 for the mean

mean: add everybody and divide by how many numbers tehre are
first count
10 numbers
add them
(79+79+91+91+91+91+98+98+118+130)=966
divide that by 10
966/10=96.6
mean=96.6

median is the number that is in the middle when you arange them in order from lowest to highest
count to 5th number or 6th and aveage them
91 is median

mode is the number tha appears most often
91 appears 4 times

modse is 91

mean=96.6
median=91
mode=91

Five less than the quotient of x and three.

Answers

Answer:

$(x)/(3)-5$

Step-by-step explanation:

We have been given a word phrase. We are supposed to write an expression for our given word phrase.

The quotient of x and 3 would be x divided by 3 as: $(x)/(3)$ .

Five less than the quotient of x and three stands for 5 subtracted from $(x)/(3)$ .

$(x)/(3)-5$

Therefore, our required expression would be $(x)/(3)-5$ .

Answer:

(x/3) - 5

Step-by-step explanation:

Five less than quotient of x and three
