Answer:
Step-by-step explanation:
Given that the random variable X is normally distributed, with
mean = 50 and standard deviation = 7.
Then we have z=
Using this and normal table we find that
a)
b) When z=0.02
we get
c) 90th percentile z value =1.645
90th percentile of X
Let
S= #small candles
L= #Large candles
S+ L =>20
3.50S + 5.00L < 80
Answer:
100
Step-by-step explanation:

You have to rearrange the equation so that it's in slope intercept form, y=mx+b. You have to move 5x and 8 to the other side of the equal sign:
2y=-5x-8
Then divide both sides by 2:
y=-5/2x-4
In y=mx+b, m is slope and b is the y-intercept. So, the slope is -5/2 and the line intersects the y-axis at the point (0,-4).
The easiest way to graph the equation is to graph the y-intercept first. Then, because the slope is -5/2, and slope is rise/run, you go DOWN 5 units and to the right 2 units from (0,-4). You repeat this multiple times. To get the points on the left side of the y-axis, you go UP 5 units and left 2 from (0,-4). Repeat.
Hello!
Explanation:
First, you convert by the mixed numbers into improper fractions.
Then, apply by the fraction rule.
Next, you had to cancel by the 2.
Finally, divide by the numbers or multiply by the numbers too.
