Answer:
20%
Step-by-step explanation:
We are asked to find the proportion of of scores in a normal distribution between the mean (z = 0.00) and z = +0.52.
We will use normal distribution table to find area under normal distribution curve corresponding to given score as:
Using normal distribution table, we will get:
Therefore, approximately 20% of scores in a normal distribution between the given z-scores.
Answer:
The missing value is 6
Step-by-step explanation:
We know that there are 5 values but only 4 are given:
⇒ The given values are: 8, 14, 7, and 13
⇒ Let the fifth value be "x"
We also know the mean which is 9.6
<em><u>Solve for the missing value:</u></em>
⇒ 9.6 (mean) =
<em>multiply 5 on both sides </em>
⇒ 9.6 x 5 = x 5
⇒ 48 = 8 + 14 + 7 + 13 + x
<em>add the numbers:</em>
⇒ 8 + 14 + 7 + 13 + x = 42 + x
<em>the equation becomes: </em>
⇒ 48 = 42 + x
<em>Now, subtract 42 on both sides:</em>
⇒ 48 - 42 = 42 - 42 + x
⇒ 6 = x
(6,5) because all of the numbers in the (x) spot have to be different to make it a function. The numbers in the (y) spot can be the same, just not the numbers in the (x) spot
Answer:
(12, 3.2) would be the max amount of gas he could buy. (11.25, 3) for an even gallon amount.
Step-by-step explanation:
The multiplicative inverse of something is a fancy way to say reciprocal.
A reciprocal is a fancy way to describe the action of flipping the fraction.
So flip 35/9 to get 9/35.
That's the multiplicative inverse.
