There are 80 girls and 70 boys in the sixth grade. Of these students, 11 girls and 7 boys are left handed. What percentage of the sixth graders are left handed?

Answers

Answer: 12%

Step-by-step explanation:

Total number of people in 6th grade: 70+80 = 150

Total numbers of lefties: 11 + 7 = 18

18 ÷ 150 = 0.12

0.12 x 100 = 12

80+70=150 which is the whole

11+7= 18 which is the part

The equation is

Part= Percent x Whole

18= % x 150 or 18 divided by 150 is

.12 or 12%

Find the median and mode(s) of the data.
1. 1,3,5,6,7,9,11

Answers

Answer:

Median: 6

Mode: No Mode

Step-by-step explanation:

To find the median, we line the numbers up in order (which it already is) and find the middle number.

In this equation, there are 3 numbers on each side and 6 in the middle so that is our median

To find the mode, we look for the most commonly used number

Since all of the numbers are used once, there is no mode

Hope this helps, have a great day, and please award brainliest

The 10-second barrier in the 100-meter dash was first broken in the 1968 Olympics, when the winning time was 9.95 seconds. A gym teacher ran the 100-meter dash in 14.7 seconds. How much faster was the 1968 Olympic time than the gym teacher’s time

HELP

Answers

Answer:

4.75 seconds

Step-by-step explanation:

14.7 - 9.95

Answer:

The Olympian completed the 100-meter dash 4.75 seconds faster than the gym teacher. You could also say he was 3.25 meters per second faster.

Step-by-step explanation:

To get 4.75 I just subtracted and found the difference between both of their times.

To find the difference between their speeds, I divided 100 by each time to get each person's distance per second. The olympian's speed was 10.05 meters per second and the gym teacher's speed was 6.80 meters per second. To find the difference between these, I subtracted the same way I did with the time difference.

Part A
Kelvin wants to know whether he skied without falling more than twice as long as anyone else in his family. His dad tells him that he can check by using the inequality 2f < 223, where f is the time skied in seconds for each person. Plug the values for the time skied by each person into the inequality to find the answer.

What is the effect of multiplying both sides of an inequality by a negative number? Explain and give an example.

Answers

Answer: You would swap the ineqaulity

Step-by-step explanation:

Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to >, and vice versa. For example, given that 5 < 8 we can multiply both sides by 6 to obtain 30 < 48 which is still true.
