Answer) 46  inches.  

Approximately 16 % of 7-year-old children are taller than 51 inches.

In the United States, birth weights of newborn babies are approximately normally distributed with a mean of  μ = 3,500 g and a standard deviation of  σ = 500 g.

What percent of babies born in the United States are classified as having a low birth weight (< 2,500 g)? Explain how you got your answer.

(Answers)

The z-score for 2,500 g is –2.

According to the empirical rule, 95% of babies have a birth weight of between 2,500 g and 4,500 g.

5% of babies have a birth weight of less than 2,500 g or greater than 4,500 g.

Normal distributions are symmetric, so 2.5% of babies weigh less than 2,500g.

m = 0

Step-by-step explanation:

Solve: Add -35m to -5m

-5m = -35m

+35m

30m = 0 *note: its okay to have 0 in this spot*

divide 0/30

m=0 because you can't divide by 0

The value of m is 7 for the given statement -5m = -35.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given an expression

-5m = -35

Divide by -5 on both sides

m = 7

Therefore, For the given expression -5m = -35 the value of m is 7.

*5.5w - 3.25 = 35.25

The 5.5w part shows that its $5.50 times each window. The -3.25 is because he deducted 3.25 from the total. And then you have the price that he got on the other side. 

Here's the work to find the windows in case you want it:

5.5w-3.25=35.25

5.5w=38.50

w=7

He washed 7 windows

Answer: -3

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

To turn a fraction into a decimal, all we need to do is divide the numerator by the denominator. But first, we can simplify! -66/22 simplifies to -3/1 when you divide by 22 on the top and bottom. Now, it's a lot easier to divide. -3/1=-3. -3 is technically already a decimal...you just can't see the decimal point. The decimal point is actually behind -3, so it looks like this: -3.0

The required first 3 terms of the sequence are 6, 2. -2.

Given that,
Then nth term of a sequence is 10-4n list the first 3 terms​ is to be determined.

Arithmetic progression is the series of numbers that have common differences between adjacent values

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
Nth term = 10 - 4n
For the first term, put n = 1
1 st term = 10 - 4 = 6
For the second term put n = 2
2nd = 10 - 8 = 2
For the third term put n = 3
