Answer:

B

Step-by-step explanation:

The length (4 inches) x the width (2 inches) of the back board gives you an answer of 8 inches

{8}^{2}

you then must find the area of the region that is not shaded so you would then use (length x width) to find the area of the unshaded region

1.5 \times 1 =    {1.5}^{2}

For the last step, subtract the area of the unshaded region from the area of the backboard to get the area of the shaded region of the backboard.

{8}^{2}  -  {1.5}^{2}  =  {6.5}^{2}

<u>In</u><u> </u><u>that</u><u> </u><u>case</u><u>,</u><u> </u><u>your</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>B</u><u>)</u><u> </u><u>6</u><u>.</u><u>5</u><u> </u><u>inches</u><u> </u><u>squared</u>

The first 5 checks are free so you can subtract the 5 from 18 which is 13. Then you multiply 13 & .25 which is equal to $3.25 and then you just add the $5

annesha travels at a rate of 50 miles per hour. morris is traveling 3 feet per second less than Aneesha. which is the best estim
Snowcat [4.5K]

The speed that Morris is travelling is 0.3 ft/s

<h3>Calculating the speed of a body</h3>

Speed is the ratio of distance covered with respect to time.

Given the following parameters

Speed of Annesha = 50mi/hr

Speed of Moris = 3ft/s less than Aneesha

Convert 50mi/hr to ft/hr

50mi/hr = 73.3ft/s

Speed of Morris = 73.3 - 3

Speed of Morris =70.3 ft/s

Hence the speed that Morris is travelling is 0.3 ft/s

The life of Sunshine CD players is normally distributed with a mean of 4.1 years and a standard deviation of 1.3 years. A CD pla
castortr0y [4]

Using the normal distribution, we have that:

a) The sketch of the situation is given at the end of this answer.

b) The probability is:

P(2.8 \leq X \leq 7) = 0.8284

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

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

  • It 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, which is the percentile of X.

In this problem:

  • Mean of 4.1 years, thus \mu = 4.1.
  • Standard deviation of 1.3 years, thus \sigma = 1.3.

Item a:

The part between 2.8 and 7 years is shaded on the sketch given at the end of this answer.

Item b:

The probability is the <u>p-value of Z when X = 7 subtracted by the p-value of Z when X = 2.8</u>, thus:

X = 7:

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

Z = \frac{7 - 4.1}{1.3}

Z = 2.23

Z = 2.23 has a p-value of 0.9871.

X = 2.8:

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

Z = \frac{2.8 - 4.1}{1.3}

Z = -1

Z = -1 has a p-value of 0.1587.

0.9871 - 0.1587 = 0.8284, thus:

P(2.8 \leq X \leq 7) = 0.8284
