"PLEASE HELP" Michah has 8.25 more chapters to read in her book. Her book is due back in the library in 6 days. Spread evenly over 6 days, how much should she read each day to finish on time?
Answer:
we need to divide 8.25 by 6 in order to get like 1.375 chapters a day
Step-by-step explanation:
plz mark brainliest i answered first
Answer:
11/8 chapters/day
Step-by-step explanation:
This is a "rate" problem. Divide 8.25 chapters by 6 days:
8.25 chapters
reading rate: ------------------------
6 days
Rewriting this as 8 1/4 chapters / 6 days makes the arithmetic a bit easier.
We then have 33/4 chapters / 6 days, or 33/24 chapters / day.
This reduces to 11/8 chapters/day.
A bonus of $156 is paid to one team of 3 workers. How much money does each person on the team get?
Answer:
$52
Step-by-step explanation:
Answer:
156 / 3 = 52

Austin has 125% more books than his younger sister. If his sister has 24 books, how many books does he have? Write your proportion below...and solve *
Answer:
30 books
Step-by-step explanation:
125%= 1.25
1.25 times 24= 30
Answer:54
Step-by-step explanation:
If we know he has 125% more books than his sister who has 24 books, then we would write 24×125%
That equations equals 30
Now you have to add 24+30 because he has 30 more books than her, so he has her amount plus his.

Solve the inequality 3p + 2 is greater than or equal to -10
Answer:
p ≥ -4
Step-by-step explanation:
3p + 2 ≥ -10 (Given)
3p ≥ -12 (subtraction property of inequality)
p ≥ -4 (division property of inequality)
[tex]\huge\underline\mathbb\pink{ANSWER\::}\\\\[/tex]
3p + 2 ≥ -10
Subtracting 2 from both sides ,
=> 3p +2 - 2 ≥ -10-2
=> 3p ≥ -12
Dividing 3 from both sides
=> [tex]\frac{3p}{3}[/tex] ≥ [tex]\frac{-12}{3}[/tex]
=> p ≥ -4
SS = {p : p≥-4}
=>{-4 , -3 , -2 , -1 , 0 , 1 , 2 , 3 , 4 , 5 , ♾️}

he probability that an individual has 20-20 vision is 0.13. In a class of 24 students, what is the probability of finding five people with 20-20 vision
Answer: 0.111947
Step-by-step explanation:
Let x be a binomial variable that represents the number of people with 20-20 vision.
Given: The probability that an individual has 20-20 vision: p= 0.13
Sample size : n= 24
Binomial probability distribution formula:
[tex]P(X=x)=^nC_xp^x(1-p)^{n-x}[/tex]
The probability of finding five people with 20-20 vision :
[tex]P(X=5)=\ ^{24}C_5(0.13)^5(1-0.13)^{24-5}\\\\=\dfrac{24!}{5!19!}(0.13)^5(0.87)^{19}\\\\=0.111946975387\approx0.111947[/tex]
Hence, the required probability = 0.111947
The probability of finding five people with 20-20 vision is 0.0461.
Binomial Probability:The formula for the Binomial Probability is,
[tex]P(X = x) =(\frac{n!}{x!(n-x)!} )\times p^x \times (1-p)^{n-x}[/tex]
Given that,
[tex]p = 0.13\\1 - p = 0.87\\n = 72\\x = 5[/tex]
Substituting the given values into the above formula we get,
[tex]P(X = x) =(\frac{n!}{x!(n-x)!} )\times p^x \times (1-p)^{n-x}\\P(X=5)=(\frac{72!}{5!(72-5)!} ) (0.13)^5(0.87)^{72-5}\\P(X=5)=0.0461[/tex]
