Answer:

.13%

68.26%

2.28%

47.72%

49.87%

34.13%

Step-by-step explanation:

1.) standardize by subtracting the mean and dividng by the standard deviation

(625-1000)/125= -3

go to a ztable to get .0013 or (1-.9987)

this is equal to .13%

2.)

875<x<1125

standardize both seperately and subtract them

(875-1000)/125= -1 whose probability is .1587 (or 1-.8413)

(1125-1000)/125= 1 whose probability is .8413

.8413-.1587= 68.26%

3.)

Find the probability that someone paid less than 1250 and take its compliment

(1250-1000)/125= 2 which has a probability of .9772

take its compliment (1-.9772)= .0228= 2.28%

4.)

Same process as question 2

(750-1000)/125= -2 which has a probability of (1-.9772) = .0228

(1000-1000)/125= 0 which has a probability of .5

.5-.0228= .4772= 47.72%

5.) same deal as the previous question

(625-1000)/125= -3 which has a probability of (1-.9987)= .0013

(1000-1000)/125= 0 which has a probability of .5

.5-.0013= .4987= 49.87%

6.)same deal the previous question

(875-1000)/125= -1 which has a probability of (1-.8413)=.1587

(1000-1000)/125= 0 which has a probability of .5

.5-.1587= .3413= 34.13%

State the independent variable and dependent variable and find the slope.

Rudik [331]

Time is your independent variable, and snowfall is your dependent variable.

Slope can be found by calculating ∆y/∆x:
$x = \frac{0.06 - 0.02}{3 - 1} \\ x = \frac{0.04}{2} \\ x = 0.02$

Snowfall will accumulate 0.02 m every hour.

You choose a movie at random from a list containing 8 comedy movies, 5 science fiction movies, and 7 adventure movies. What is t

IRISSAK [1]

Answer:

3/5

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

the theoretical probability that the movie is not a comedy = number of movies that are not comedies / total movies available

12/ 20 = 3/5

About ______% of the area is between z= -1 and z= 1 (or within 1 standard deviation of the mean)? How do you solve this?

nexus9112 [7]

Answer:

68%

Step-by-step explanation:

68-95-99.7% Rule:

This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:

68% of the data fall within 1 standard deviation of the mean
95% of the data fall within 2 standard deviation of the mean, and
99.7% of data falls within 3 standard deviations of the mean

Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)
