7 goes into 20, 2 times oh whatever the answer is
2 and 6/7
Answer:
Ben's rate is 
greater than Kate's rate.
Step-by-step explanation:
1. If it takes Ben 2 days to write reports, then his rate is 
of reports per day.
2. If it takes Kate 3 days to write reports, then her rate is 
of reports per day.
3. Ben's rate is
greater than Kate's rate.
Answer:
C
Step-by-step explanation:
For the given intervals
( - ∞, - 5) ← use any value < - 5 but not - 5, the parenthesis ) indicates that x is less than - 5 but not equal to - 5
(- 5, - 1) ← - 4, - 3, - 2 can be used but not - 5 or - 1
(- 1, 4) ← 0, 1, 2, 3 can be used but not - 1 or 4
(4, ∞ ) ← use any value > 4 but not 4
Hence
3 can be used in (- 1, 4)
- 6 can be used in (- ∞, - 5)
zero can be used in (- 1, 4)
- 5 cannot be used in any of the given intervals
Answer:
A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. so its A

i looked it up and i think this is right :)
Doing factorization, we know that the factors of the given equation are ±√5 and ±10i.

What is Factorization?</h3>
In mathematics, factorization or factoring consists of writing a number or any mathematical item as a product of several factors, typically small or easier objects of the same.
For example, 3 × 5 is a factorization of an integer 15 and is a factorization of an equation x² – 4.
So, we have the equation:
x⁴ + 95x² – 500 = 0
Factorizing the above equation:
x⁴ + 100x² - 5x² - 500 = 0
x²(x² + 100) - 5(x² + 100) = 0
(x² - 5)(x² + 100) = 0
Solving further:
x² = 5
x² = -100
x = ±√5
x = √-100
Factors: ±√5 and ±10i
Therefore, doing factorization, we know that the factors of the given equation are ±√5 and ±10i.
