A group of students weighs 500 US pennies. They find that the pennies have normally distributed weights with a mean of 3.1g and

Question 1

probability between 2.8 and 3.3

The graph of the normal distribution is shown in the diagram below. We first need to standardise the value of X=2.8 and value X=3.3. Standardising X is just another word for finding z-score

z-score for X = 2.8
z= \frac{2.8-3.1}{0.41} =-0.73 (the negative answer shows the position of X = 2.8 on the left of mean which has z-score of 0)

z-score for X = 3.3 
z= \frac{3.3-3.1}{0.41}=0.49

The probability of the value between z=-0.73 and z=0.49 is given by 
P(Z<0.49) - P(Z<-0.73)

P(Z<0.49) = 0.9879
P(Z< -0.73) = 0.2327 (if you only have z-table that read to the left of positive value z, read the value of Z<0.73 then subtract answer from one)

A screenshot of z-table that allows reading of negative value is shown on the second diagram

P(Z<0.49) - P(Z<-0.73) = 0.9879 - 0.2327 = 0.7552 = 75.52%

Question 2
Probability between X=2.11 and X=3.5

z-score for X=2.11
z= \frac{2.11-3.1}{0.41}=-2.41

z-score for X=3.5
z= \frac{3.5-3.1}{0.41} =0.98

the probability of P(Z<-2.41) < z < P(Z<0.98) is given by
P(Z<0.98) - P(Z<-2.41) = 0.8365 - 0.0080 = 0.8285 = 82.85%

Question 3
Probability less than X=2.96

z-score of X=2.96
z= \frac{2.96-3.1}{0.41}=-0.34
P(Z<-0.34) = 0.3669 = 36.69%

Question 4
Probability more than X=3.4
z= \frac{3.4-3.1}{0.41}=0.73
P(Z>0.73) = 1 - P(Z<0.73) = 1-0.7673=0.2327 = 23.27%

Multiple step problem<br>-6 = 2 (w+5) ​
Romashka-Z-Leto [24]

Answer:

w = -8

Step-by-step explanation:

Distribute: -6 = 2w + 10

Remove the 10: -6 -10 = 2w +10 -10 ---> -16 = 2w

Isolate the variable: -16/2 = 2w/2

Answer: -8 = w

16 is what percent of 24
Blababa [14]
100%/x%=24/16
(100/x)*x=(24/16)*x       - we multiply both sides of the equation by x
100=1.5*x       - we divide both sides of the equation by (1.5) to get x
100/1.5=x
66.6666666667=x
x=66.6666666667

now we have:
<span>16 is 66.6666666667% of 24</span>
