16m + 6n
Answers
Using the distributive law to factor, the expression becomes 16m + 6n = 2(8m + 3n)
GIven three integers A, B and C, according to the distributive property;
A(B+C) = AB + BC
Given the expression 16m + 6n
First, we need to get the factors of both terms
16m = 2 * 8 * m
6n = 2 * 3 * n
From both factors, we can see that 2 is common to both of them. Hence using the distributive law to factor, the expression becomes;
16m + 6n = 2(8m + 3n)

The weight of people in a small town in Missouri is known to be normally distributed with a mean of 162 pounds and a standard deviation of 28 pounds. On a raft that takes people across the river, a sign states, “Maximum capacity 3,401 pounds or 19 persons.” What is the probability that a random sample of 19 persons will exceed the weight limit of 3,401 pounds?
Answers
Using the normal distribution relation, the probability that sample will exceed the weight limit is 0.004
Using the relation ::
Zscore =(X - μ) ÷ σThe mean, μ = np = (162 × 19) = 3078
The standard deviation, σ = 28 × √19 = 122.049
The Zscore :
Zscore = (3401 - 3078) ÷ (122.049)
Zscore = 2.65
Hence,
P(Z > 2.65) = 1 - P(Z < 2.65)
Using a normal distribution table :
P(Z > 2.65) = 1 - 0.9959
P(Z > 2.65) = 0.004

5) y = 6x - 3
6) y = 2
Step-by-step explanation:
If we’re trying to write a line in slope-intercept form, we must need the slope and the y-intercept.
m = 6 and b = -3
What the question is trying to say is that 6 is the slope and -3 is the y-intercept. Thus m = slope and b = y-intercept.
And the equation of the line in slope-intercept form is y = 6x - 3
but what if the slope is 0 like in question 6? Therefore, we cancel the slope and x-intercept DOES NOT appear. so the equation of the line would be y = 2

Answers
Answer:
40°F
Step-by-step explanation:
When Tyrese fell asleep one night, the temperature was 24°F.
When Tyrese awoke the next morning, the
temperature was -16°F.
Letting + denote a rise in
temperature and - denote a drop in temperature, what was the change in temperature from the time Tyrese fell asleep until the time he awoke?
The temperature dropped from a high temperature to a low one : from 24° to -16°
This can be expressed mathematically as 24 - (-16), with - denoting a drop in the temperature
=24-(-16)
=24+16

Write first natural number after 10999:
10999 + 1 = 11000
Write second natural number after 11000:
11000 + 1 = 11001
Write the third natural number after 11001:
11001 + 1 = 11002
Hence, the next three natural numbers after 10999 are 11000, 11001, and 11002.

An item costs 490before tax, and the sales tax is39.20 .
Find the sales tax rate. Write your answer as a percentage.
Answers
Answer:
8% is the sales tax rate
Step-by-step explanation:
I'm not the best with math but the way I found the answer was by first using my local sales tax rate and determining how much the tax would be.
490 * 8.75% = 42.875
Knowing that this amount was higher than in the equation, I lowered the sales tax to 8% (0.08)
490 * 8% = 39.2
