Answer:
- 4 / 10 (or -2/5 if you need to simplify)
Step-by-step explanation:
using the point-slope formula, m = (y2-y1) / (x2 - x1)
using the ordered pairs, you get
m = (-2 - 2) / (3 - -7)
m = (-4) / (10)
m= -4/10
if you need to reduce, it's -2/5

"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.

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]

A bike shop marks up a hybrid bike from $200 to $330 and discounts a road bike from 330 to 200 by what you percent is the road bike discounted . I need the answer ASAP
Answer:
39.39%
Step-by-step explanation:
There's a nice little formula that is used to find percentage change which works regardless of if it's an increase or decrease.
[tex]Percent~Change = |\frac{New~Value~-~Original~Value}{Original~Value}| * 100[/tex]
1 - Understanding the equation
The '|'s which are surrounding the fraction are absolute value symbols in mathematics,
Absolute value means the positive value of anything inside
Examples:
| -8 | = 8
| 8 | = 8
and
| -2 | = 2
| 2 | = 2
the * 100 means you multiply (the * symbol means multiply) by 100.
We do this to get it into a percent.
3 - Assign numbers to the values from our equation
Original Value (What it changed from): 330
New Value (What it changed to): 200
3 - Plug in our values into our variables from our equation[tex]Percent~Change = |\frac{200-330}{330}| * 100 = |\frac{-130}{330}| = = |-0.39...| * 100 = 0.3939... *100 =[/tex]
Our percent change is 39.39%, and with our percent in which is discounted being the same, we have our answer.
Hope this helps :)

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 ,

Dividing 3 from both sides

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.
