You go to Dairy Queen for a single serving. Their distribution for single serving is bellshaped with a mean of 8 ounces and a standard deviation of 0.25 oz. x = s =
Draw the bell-shaped model below, labeling the mean and each standard deviation above and
below the mean.
a. What percentage of servings are between 7.75 oz. and 8.25 oz.?
(think how many standard deviations away from the mean do 7.75 and 8.25 fall?)
b. What percentage of servings are between 7.5 oz. and 8.5 oz.?
(think how many standard deviations away from the mean do 7.5 and 8.5 fall?)
c. What interval contains 99.7% of the servings?
(think how many standard deviations away from the mean does 99.7% of the values fall?)
d. Suppose your serving weighs 8.5 ounces, what percentage of servings are smaller
than yours?
(think where is 8.5 located with respect to the mean?)

they will manufacture 8496 cars

300pi

step-by-step explanation:

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
