Answer and Explanation:
Number of classes = 8
Highest value =2300
Lowest value = 1250
Class width= highest value – lowest value / number of classes
= 2300 – 1250/8
= 131.25 = 132
So, we can write class as 1250+132=1382
Class frequency
1250-1382 2
1382-1514 3
1514-1646 6
1646-1778 2
1778-1910 3

Four-fifths of a number equals 16. Find the number.
The number is 20
The number is 31
The number is 17
Answer:
The number is 20
Step-by-step explanation:
Four-fifths = 4/5
Let the number = x
4/5 of x = 16
4/5 * x = 16
4/5x = 16
Divide both sides by 4/5
x = 16 ÷ 4/5
= 16 × 5/4
= 80 /4
= 20
Therefore, the number is 20

you pay 9.70 for 2.5 pounds of roasted peanuts. You buy 1.4 pounds of almonds for 8.55 per pound.
How much less do roasted peanuts cost per pound than almonds?
How much more do you spend on almonds than on roasted peanuts.
$9.70 / 2.5lbs = $3.88 / pound of roasted peanuts.
$8.55 * 1.4lbs = $11.97 / 1.4 pounds of almonds
$8.55 - $3.88 = $4.67.
Roasted peanuts cost $4.67 less per pound than almonds.
$11.97 - $9.70 = $2.27
You spend $2.27 more on almonds than you do roasted peanuts.

M is between L and N. If LN = 91 and LM = 23, find MN.
Answer:
MN = 68
Step-by-step explanation:
LN = 91
LM = 23
Points L, M, and N are collinear, therefore, according to the segment addition postulate, the following can be deduced:
LM + MN = LN
23 + MN = 91 (Substitution)
Subtract 23 from both sides
23 + MN - 23 = 91 - 23
MN = 68

What is Least Common Multiple(LCM)?The least common multiple is defined as the least positive integer that is dividable by both given numbers.
A group's Least Common Multiple (LCM) is the smallest number that is a multiple of all the numbers. For example, the LCM of 4 and 5 is 20; 20 is the smallest number that is both a multiple of 4 and a multiple of 5
To solve this problem, we need to find the least common multiple (LCM) of the two sequences of days, 3 and 4.
The LCM of 3 and 4 is 12, which means that after every 12 days, Max and Ellen will both be at the gym on the same day.
Starting from Monday, the next time Max and Ellen are at the gym together will be 12 days later, which is a Saturday.
Hence, the answer is an option (D) Saturday.

Given the function y= 2x if x>0 x−3 if x≤0 . Find its values for x=1; 3; 0; −2. Answer: If x = 1, then y = . If x = 3, then y = . If x = 0, then y = . If x = −2, then y = .
Answer:
Step-by-step explanation:
Given the function y= 2x if x>0 and x−3 if x≤0, to find the value of the function for x = 1, we will substitute x = 1 into the function y = 2x since x>0 at that point.
If x = 1;
y = 2(1)
y = 2
Hence when x = 1, y = 2
If x = 3, we will still use the function y = 2x since 3 is still grater than 0 satisfying the condition x>0.
y = 2(3)
y = 6
Hence when x = 3, y = 6
when x = 0, since x is zero, we will substitute x = 0 into the function x-3 because x≤0 at this point.
If y = x-3
y = 0-3
y = -3
Hence when x = 0, y = -3
when x = -2, we will substitute x = 0 into the function x-3 because -2 is also less than zero
If y = x-3 for x≤0
y = -2-3
y = -5
Hence when x = -2, y = -5
find x

x=2
