<h2>Answer:</h2>

The statement "line plots display individual data" is TRUE.

Step-by-step explanation:

A line plot provides an orderly display of all the values in a data set. It displays data as points above a number line to show the frequency of each value denoted by X. This method is a simple and quick way to organize any given data. But this is not useful for very large data set. Generally a data size of 25 to 30 entities is enough for this kind of method.

Lost-time accidents occur in a company at a mean rate of 0.40.4 per day. What is the probability that the number of lost-time ac

o-na [289]

Answer:

1.32% probability that the number of lost-time accidents occurring over a period of 88 days will be no more than 22.

Step-by-step explanation:

To solve this question, i am going to approximate the Poisson distribution to the normal to solve this question.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given time interval. The variance is the same as the mean.

Normal probability distribution:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The poisson distribution can be approximated to the normal with mean $\mu$ and standard deviation $\sigma = \sqrt{\mu}$

In this problem, we have that:

88 days

0.4 accidents per day

$\mu = 88*0.4 = 35.2$

$\sigma = \sqrt{35.2} = 5.933$

Probability of no more than 22 accidents:

pvalue of Z when X = 22. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{22 - 35.2}{5.933}$

$Z = -2.22$

$Z = -2.22$ has a pvalue of 0.0132

1.32% probability that the number of lost-time accidents occurring over a period of 88 days will be no more than 22.

ABOUT THIS TUTOR ›

y=mx + b is the standard slope intercept form for a line

m=1/2, b =-2

y=(1/2)x -2. y-intercept is -2 or the point (0,-2)

x intercept is found by setting y=0 and solving for x

0=(1/2)x - 2

(1/2)x = 2

x = 4 = the x intercept or (4,0)

plot the 2 intercepts (0,-2) and (4,0)

(4,0) is on the x axis, 4 units to the right of the origin (0,0)

(0,-2) is on the y axis, 2 units below the origin

once you plot those two points, draw a straight line connecting them. That's the graph of the line

20 POINT!!<br> Can someone help me I don’t understand it at all

sammy [17]

Answer:

second

Step-by-step explanation:

substitute y=6 and x=1 in the given relations and see if works

y=2x will be 6 = 2*1 false

y=x+5 will be 6 = 1+5 true

because this is true check all the other y and x and if all true is good

7=2+5 true, 8=3+5 true 9= 4+5 true, 10=5+5 true, so second is good

y=2x+1 will be 6=2*1+1 false

y=3x+1 will be 6=3*1+1 false

There are 12 students in the pep squad.Three students are wearing white shirts.Six students are wearing blue shirts. What fracti

Viktor [21]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Total number of the students in the pep squad = 12 students

The number of the students wearing white shirts = 3 students

The number of the students wearing blue shirts = 6 students

Either white or blue shirts indicate that the students wearing white shirt or blue shirt.

Thus, number of students wearing either white or a blue shirt = 3 + 6 students = 9 students

So,

The fraction is:- $\frac{9}{12}=\frac{3}{4}$
