Answer:
y= -5x-5
Step-by-step explanation:
Y is equal to 5 less than -5 times x, which means it is 5 less than -5x.
If y is 5 less than -5x, that means it is equal to -5x-5.
If you were to put that in an equation, it would be y= -5x-5
Hello
Your answer is
0.581
And remember,any number divided by 10,100,1000 and its smaller it will be the same number,but in decimal form
Good luck!
Answer:
0.96%
Step-by-step explanation:
Well the easy way to do this is
1.262
- - - - - - - x 100 = 100.96%
1.25
( this is just saying, now the thing is 100.96% of it original size)
So now they are asking the increase, so just simply take
100.96 - 100
= 0.96%
The probability that a randomly selected adult has an IQ less than
135 is 0.97725
Step-by-step explanation:
Assume that adults have IQ scores that are normally distributed with a mean of mu equals μ = 105 and a standard deviation sigma equals σ = 15
We need to find the probability that a randomly selected adult has an IQ less than 135
For the probability that X < b;
- Convert b into a z-score using z = (X - μ)/σ, where μ is the mean and σ is the standard deviation
- Use the normal distribution table of z to find the area to the left of the z-value ⇒ P(X < b)
∵ z = (X - μ)/σ
∵ μ = 105 , σ = 15 and X = 135
∴ 
- Use z-table to find the area corresponding to z-score of 2
∵ The area to the left of z-score of 2 = 0.97725
∴ P(X < 136) = 0.97725
The probability that a randomly selected adult has an IQ less than
135 is 0.97725
