Answer:
48
Step-by-step explanation:
60-12=48 will be your answer of 4$ per gallon
Combine like terms you add -10x and 3x which is -7x-4
Answer:
After 20 years the investment will be worth 11,000$
Step-by-step explanation:
in order to solve the problem you have to turn the percent into a decimal by moving the percent sign twice to the left. which will result in ".11"
then you multiply 5,000x.11 and it equals to 550 per year.
multiply 550x20 and you get 11,000
if I'm not correct please tell me the right answer! goodluck!
The proportion of employees in entry-level positions at the company who earn at least $ 42,000 will be 0.48466.
<h3>What is a normal distribution?</h3>
The Gaussian distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
According to a recent survey, the salaries of entry-level positions at a large company have a mean of $ 41,750 and a standard deviation of $ 6500.
Assuming that the salaries of these entry-level positions are normally distributed.
Then the proportion of employees in entry-level positions at the company who earn at least $ 42,000 will be
The z-score is given as
z = (x - μ) / σ
Then we have
z = (42000 - 41750) / 6500
z = 0.03846
Then we have
P(x ≥ 42000) = P(z ≥ 0.03846)
P(x ≥ 42000) = 1 - P(z < 0.03846)
P(x ≥ 42000) = 1 - 0.51534
P(x ≥ 42000) = 0.48466

You have to make the fraction into an integer. the simplest version of a ratio involves the smallest possible integers. therefore, 5:2.5 will equal 10:5 (you multiply both sides by 2). 10:5 cancels down to 2:1. hope this helped :)
