Remember when you see those two signs next to each other its “kao” which is keep add opposite so for b its 6-(-3) but you do keep add opposite so now it’s 6+3=9. for c it’s -2-(-5) and we still do kao which now it’s -2+5 different signs you subtract so now it’s 3 we always keep the sign of the higher variable and 5 is positive so the answer is positive.

A 6th grade football team played six games and scored 17, 14, 30, 24, 21, and 14 points. In their seventh game,
zheka24 [161]

Answer:

a. Mean

a. 79 points is an outlier, and the mean is most responsive to outliers.

Step-by-step explanation:

17, 14, 30, 24, 21, and 14

Let's calculate the measure of central tendency of the numbers first.

Mean = 120/6

Mean = 20

For Median

Let's arrange the numbers in ascending order

14,14,17,21,24,30

The median is 17 and 21

Median value =( 17+21)/2

Median = 38/2

Median = 19

Mode = 14.

After 79 was added.

Mean =( 120+79)/7

Mean = 199/7

28.43

For Median

14,14,17,21,24,30,79

Median= 21

Mode = 14

The value that changed the most was the mean value.

When Mei does 17 push-ups and 6 sit-ups, it takes a total of 35 seconds. In comparison, she needs 41 seconds to do 20 push-ups a
Romashka [77]

Answer:

It takes 1 seconds for push-ups and 3 seconds for sit-ups for Mei to do exercise.

Step-by-step explanation:

Given:

Let the time taken for push-ups be 'x'.

Let the time taken for sit-ups be 'y'.

Now Given:

17 push-ups and 6 sit-ups, it takes a total of 35 seconds.

So we can say that;

17x+6y=35 \ \ \ \ equation \ 1

Also Given:

41 seconds to do 20 push-ups and 7 sit-ups.

so we can say that;

20x+7y=41 \ \ \ \ equation \ 2

Now Multiplying equation 1 by 7 we get;

7(17x+6y)=35\times7\\\\119x+42y= 245 \ \ \ \ equation \ 3

Now Multiplying equation 2 by 6 we get;

6(20x+7y)=41\times6\\\\120x+42y = 246 \ \ \ \ equation\ 4

Now Subtracting equation 3 from equation 4 we get;

120x+42y-(119x+42y)=246-245\\\\120x+42y-119x-42y=1\\\\x=1\ sec

Now substituting the value of x in equation 1 we get;

17x+6y=35\\\\17\times1+6y=35\\\\17+6y=35\\\\6y=35-17\\\\6y= 18\\\\y=\frac{18}6 = 3\ seconds

Hence It takes 1 seconds for push-ups and 3 seconds for sit-ups for Mei to do exercise.

What would my final balance be if i put $650 in the bank for 60 months with an interest rate of 6%?
Flauer [41]
Your final balance would be $2,340.

I = Prt
Percent (6%) x rate (650) x time (60 months) = 2,340

6% = 0.06

0.06 x 60 x 650 = 2,340
