Mister Parts recorded the number of absent students at Brighton Middle School last week what was the mean number of absent stude

serg [7]

A. 8.8 students per day on average were absent.

1) If the absence recorded was:

On Monday: 11

On Tuesday: 9

On Wed: 6

On Thu: 9

On Fri: 9

2) Since the number of weekdays were 5 we can calculate the mean of absent students by adding all those absences and dividing by 5

So, 11+9+6+9+9+9 =44

Dividing by 5

So the mean or the average of the absence was 8.8

The owner of a convenience store keeps track of how many customer buy lunch food during the "noon rush" each day for four days a

alexdok [17]

Answer:

c) 62.

Step-by-step explanation:

Let x represent number of customers came in on the fifth day.

We have been given that the mean number of customers for those four days is 52. So total number of customers on 4 days would be 4 times 52 that is 208 customers.

We know that mean of a data set is equal to sum of all data points divided by number of data points.

Total number of customers on 5 days would be $208+x$ and total number of days is 5.

Since we need a mean of 54, so we can set mean of 5 days equal to 54 as:

$\frac{208+x}{5}=54$

Multiply both sides by 5:

$\frac{208+x}{5}*5=54*5$

$208+x=270$

$208-208+x=270-208$

$x=62$

Therefore, 62 customers must come in on the fifth day to make the five-day mean 54 and option 'c' is the correct choice.

At a college, the cost of tuition increased by 10%. Let b represent the former cost of tuition. Use the expression b+0.10b for

kirza4 [7]

Question is Incomplete,Complete question is given below;

At a college, the cost of tuition increased by 10%. Let b be the former cost of tuition. Use the expression b + 0.10b for the new cost of tuition.

a) Write an equivalent expression by combining like terms.

b) What does your equivalent expression tell you about how to find the new cost of tuition?

Answer:

a. The equivalent expression is $1.1b$ .

b. The new cost of tuition is 1.1 times the former cost of tuition.

Step-by-step explanation:

Given:

Former cost of tuition = $b$

the cost of tuition increased by 10%.

New cost of tuition = $b+0.10b$

Solving for part a.

we need to find the equivalent expression by combining the like terms we get;

Now Combining the like terms we get;

new cost of tuition = $b(1+0.1) = 1.1b$

Hence The equivalent expression is $1.1b$ .

Solving for part b.

we need to to say about equivalent expression about how to find the new cost of tuition.

Solution:

new cost of tuition = $1.1b$

So we can say that.

The new cost of tuition is 1.1 times the former cost of tuition.

(-10) - |(-20) – (+30) |

myrzilka [38]

ANSWER: -60

EXPLANATION: To solve for (-10) - |(-20) – (+30) |, we need to do:

−10−| −20 − 30|, which equals −10−|−50|. Next, we do −10−50, which is -60.

−10−|−20−30|

= −10−|−50|

= −10−50

= −60
