The cuic equation is -1 and 2i
Given:
Number of students = 35
Two out of every five boys in the club are boys.
To find:
The number of students in the club that are boys.
Solution:
Two out of every five boys in the club are boys. It means, the ratio of boys to the total number of student is 2:5.
Let the number of boys be 2x and number of students be 5x.
According to the question,


Now, the number of boys is


Therefore, 14 students in the club are boys.
Answer:
18 km/hr
Step-by-step explanation:
To find the unit rate, we must find the rate in kilometers per hour.
Let’s divide the total kilometers by the total number of hours.
unit rate = kilometers/hours
Juan rode 72 kilometers in 4 hours.
unit rate = 72 kilometers/ 4 hours
unit rate = 72 km/4 hrs
unit rate = 18 km / hr
The unit rate is 18 kilometers per hour.
You are correct
12.2^2 x 3.14 x 6.1 = 2850.9
In normal distribution, 68% of the values are within +_ 1 SD. That leaves 32% outside that range. Thus, 32 people with greater than 13, 100 people greater than 14 (200*0.68/2+32)
