Let
x-------> the number
we know that
1) The phrase “the difference of a number and 5” can be written as
(x-5)
2) The phrase “twice the difference of a number and 5” can be written as
2*(x-5)
therefore
<u>the answer is the option</u>
1. 2(x-5)
Answer:
Step-by-step explanation:
Answer:
P(x< 18) = 0.986
Step-by-step explanation:
Step 1: find the z-score using the formula, z = (x - µ)/σ
Where,
x = randomly chosen values = 18
µ = mean = 7
σ = standard deviation = 5
Proportion of the population that is less than 18 = P(x < 18)
Plug in the values into z = (x - µ)/σ, to get z-score.
z = (18 - 7)/5
z = 11/5 = 2.2
Step 2: Find P(x< 18) = P (z<2.2) using z-table.
The probability that corresponds with z-score calculated is 0.986.
Therefore,
P(x< 18) = 0.986
Answer:
The answer is 140
Step-by-step explanation:
You multiply 400 by 0.35 to get your answer. So, it would be 140 :) Hope i helped!
A) Let x stand for time, y stand for velocity.
We are given the points (2,50), (6, 54). We can make a line using the slope intercept form
y = mx + b.
slope is (54 - 50)/(6-2) = 4/4 = 1
y = 1x + b
plug in point (2,50) to find b
50 = 1(2) + b
50-2 = b
48 = b
the equation is y = 1x + 48
Make standard form.
<span>x - y = -48

Table Is attached.
Good Luck!
