To find the number of words she can read per minute, we would do 560 divide by 7 minutes
560/7 = 80 words per minute
Hope this helps
Answer:
0.09
Step-by-step explanation:
Given that 50% of this population prefers the color green.
Let p the probability that one person selected from the population prefer the green color of the car. So,
p=0.05
There is only two chance, any person either prefer the green color or not, assuming this holds true for every person, so the mentioned population can be assumed as Bernoulli's population.
By using Bernoulli's theorem, the probability of exactly r success of n randomly selected from the Bernoulli's population is

Here, 15 buyers are randomly selected, so, n= 15 and

So, by using equation (i), the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is



=0.0916
Hence, the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is 0.09.
The equations have been computed below
<h3>How to illustrate the information?</h3>
3(x + 2) + 11 = 5(x - 4)
3x + 6 + 11 = 5x - 20
Collect like terms
3x - 5x = -20 - 17
-2x = -37
x = 37/2
x = 18.5
6x + 4 = 3(3 - 2x)
6x + 4 = 9 - 6x
Collect like terms
6x + 6x = 9 - 4
12x = 5.
x = 5/12

Answer:
2.2 ft ( to 1 dec. place )
Step-by-step explanation:
The arc length is calculated as
arc = circumference × fraction of circle
= 2πr × 
= 2π × 7 × 
= 14π × 
=
