Use the distributive property to rewrite the expression 5(4x. + 7)
Answer: The answer is 20x + 35
Step-by-step explanation: 5(4x+7) You multiply 5 in both numbers and you get 20x+35
Answer: 20x+35
Step-by-step explanation:
Multiply both terms in the parenthesis by 5. 4x times 5 is equal to 20x, and 7 times 5 is equal to 35.

Suppose the heights of the members of a population follow a normal
distribution. If the mean height of the population is 65 inches and the
standard deviation is 3 inches, 68% of the population will have a height within
which range?
A. 59 inches to 71 inches
B. 53 inches to 77 inches
C. 62 inches to 68 inches
D. 56 inches to 74 inches
Answer:
C; 62 to 68 inches
Step-by-step explanation:
Here, we want to get the population range that is having a probability of 68%
From the empirical rule, a measure of 1 standard deviation above the mean, with 1 standard deviation below the mean will give a total percentage of 68%
From the question;
1 standard deviation above the mean is 65 + 3 = 68
1 standard deviation below the mean is 65-3 = 62
so the range of the height of the population is 62 to 68 inches

Answer:
3/4
Step-by-step explanation:
Total number of cases = 8 [1,2,4,2,5,3,1,2]
No. of number less than 4 = 6 [1,2,2,3,1,2]
Probability = 6/8 = 3/4
Answer: 75%
Step-by-step explanation:
Well there are 8 possibilities every time you spin. The chance is 6/8 that you land on a number less than 4, if you spin it once (since 6 out of the 8 possibilities are less than 4). So you just have to divide 6/8 which is 0.75. Multiply by 100 (move the decimal over 2 times to the right) to get the percentage which is 75%.

Suppose a city with population 600,000 has been growing at a rate of 4% per year. If this rate continues, find the population of this city in 25 years.
Answer:
15,600,000
Step-by-step explanation:
We start with our initial population of 600,000. Then multiply that with the rate of 4% (0.04 in decimal, or 1.04 so that the 0.04 is automatically added to the 600,000.)
600,000 · 1.04y = projected populationy = 25600,000 · 1.04(25) = projected populationsimplify!15,600,000 = proejcted populationWhat is b in the equation 15 + b = 23?

Jordyn is weighing ingredients on a kitchen scale to make bread. The bowl weighs 1½ pounds. He adds several scoops of flour. The total weight of the bowl and the flour is 2¾ pounds. If each cup of flour weighs 5/16 pound, how many cups of flour does he add? Show your work.
Answer:
Weight of the flour = 5/4 pounds
Number of cups added = 4 cups
Step-by-step explanation:
Weight of the bowl = 1½ pounds
Total weight of the bowl and the flour = 2¾ pounds
Weight of the flour = Total weight of the bowl and the flour - Weight of the bowl
= 2¾ pounds - 1½ pounds
= 11/4 - 3/2
= 11-6/4
= 5/4 pounds
Weight of the flour = 5/4 pounds
If each cup of flour weighs 5/16 pound, how many cups of flour does he add
Number of cups added = 5/4 ÷ 5/16
= 5/4 × 16/5
= (5*16)/(4*5)
= 80/20
= 4
Number of cups added = 4 cups

Kam is trying to find the solution to the system below. Her steps are below as well.
What did kam do wrong?
Answer:
Step 4
Step-by-step explanation:
In step 4, instead of adding 22 to both sides of the equation to combine like terms, Kam got rid of it completely. Starting from step 3, here is the correct way of solving it:
[tex]7x-22=18[/tex]
Add 22 to both sides
[tex]7x-22+22=18+22\\7x=40[/tex]
Divide both sides by 7 to isolate x
[tex]\frac{7x}{7}=\frac{40}{7} \\x=\frac{40}{7}[/tex]
I hope this helps!
Answer:
In step 4, she forgot to add 22 to 18
Step-by-step explanation:
In step 4, she forgot to add 22 to 18
It should've been:
7x = 40
x = 40/7
3 (40/7) + 2y = 18
120/7 + 2y = 18
2y = 18 - 120/7
2y = 6/7
y = 3/7

Last option is the correct answer
n = b + 2/ b= 5
Step-by-step explanation:
Question 1
The given information can be framed into the Mathematical form as given below:
No of cards = x
Cards given to brother = 55
Remaining cards = x - 55
Total number of cards = y
y = x - 55
Plug y = 200
200 = x - 55
20. + 55 = x
x = 255
y = x - 55/ x = 255
Question 2:
Total number of shirts bought
n = b + 2
Plug n = 7
7 = b + 2
7 - 2 = b
b = 5
n = b + 2/ b = 5

There are 6 times as many males as females on the maths course at university. What fraction
of the course are male?
Give your answer in its simplest form.
Answer:
Fraction of females enrolled in the course = 6 / 7
Step-by-step explanation:
Suppose that
Total Number of males = x
Total Number of females = 6x
Total Number of Students = 6x + x = 7x
Now, we have to find the what fraction of the course females candidates constitute.
Female Fraction = Total Females : Total Students
Female Fraction = 6x : 7x
Female Fraction = 6 : 7
Female Fraction = 6 / 7
So Total number of females enrolled in the course constitute the fraction = 6 / 7

If ray OC stands on line AB such that ∠AOC = ∠BOC, then find ∠BOC.
Answer:
Here OP bisect ∠BOC
∴∠POC=∠BOP …………(i)
and OQ bisect ∠AOC
∴∠AOQ=∠COQ …………….(ii)
and ∠AOB=180

[∵AOB is a straight line]
⇒∠BOP+∠DOC+∠COQ+∠AOQ=180
o
⇒∠POC+∠POC+∠COQ+∠COQ=180
