First we have to find how much gas was used:
We divide 3.3 by 129 to see how many 3.3 is in 129 (if that make sense)
However, we will get 39.09
Since one gallon is 3.3 miles then 39.09 gallons of gas was used.
So how much is now left we minus 180-39.09 = 140.91
We now find what percentage is 140.91 of 180.
n/100 × 180 = 140.91
n/100 = 140.91/180
n/100 =
n = 0.7828*100
n = 78.28

There n is equal to 78 % to the nearest percent

Would it be B which is 51%
as you do 129 devided by 3.3 = 39.1
180-39.1= 141
141 is just over half

Simplify the following expression.

HACTEHA [7]

Remember that exponentioal rule
x^m times x^n=x^(m+n)
therefor
7^4 times 7^-6=7^(4-6)=7^(-2)
remember the other rule
x^-m=1/(x^m) so
7^-2=1/(7^2)=1/49

In a standard normal distribution, what z value corresponds to 17% of the data between the mean and the z value?

hjlf

You're looking for a value $z$ such that

$\mathbb P(0$

Because the distribution is symmetric, the value of $z$ in either case will be the same.

Now, because the distribution is continuous, you have that

$0.17=\mathbb P(0$

The mean for the standard normal distribution is $0$ , and because the distribution is symmetric about its mean, it follows that $\mathbb P(Z$ .

$0.17=\mathbb P(Z$

You can consult a $z$ score table to find the corresponding score for this probability. It turns out to be $z\approx0.4399$ .
