A construction zone on Interstate 15 has a speed limit of 40 mph. The speeds of vehicles passing through this construction zone are normally distributed with a mean of 44 mph and a standard deviation of 3 mph.

Required:
a. Find the percentage of vehicles who pass through this construction zone who are exceeding the posted speed limit.
b. What percentage of vehicles travel through this construction zone with speeds between 50 mph and 55 mph?

Answers

Answer:

a. The percentage of vehicles who pass through this construction zone who are exceeding the posted speed limit =90.82%

b. Percentage of vehicles travel through this construction zone with speeds between 50 mph and 55 mph= 2.28%

Step-by-step explanation:

We have to find

a) P(X>40)= 1- P(x=40)

Using the z statistic

Here

x= 40 mph

u= 44mph

σ= 3 mph

z=(40-44)/3=-1.33

From the z-table -1.67 = 0.9082

a) P(X>40)=

Probability exceeding the speed limit = 0.9082 = 90.82%

b) P(50<X<55)

Now

z1 = (50-44)/3 = 2

z2 = (55-44)/3= 3.67

Area for z>3.59 is almost equal to 1

From the z- table we get

P(55 < X < 60) = P((50-44)/3 < z < (55-44)/3)

= P(2 < z < 3.67)

= P(z<3.67) - P(z<2)

= 1 - 0.9772

= 0.0228

or 2.28%

The guidance office at a high school surveyed their 12th grade students to know in which of four states they would prefer to live in after highschool. The results are summarized in the tso way frequency table below.

Which two-way table accurately represents the relative frequency for the whole table in this situation?

Answers

Hence, the two way frequency table is:

Action Drama Comedy total

Highschool 26/128=0.20 14/128=0.11 22/128=0.17 0.48

College 20/128=0.16 28/128=0.22 18/128=0.14 0.52

----------------------------------------------------------------------------------------------------------

total 0.36 0.33 0.31 1

Step-by-step explanation:

" When a two-way table displays percentages or ratios (called relative frequencies), instead of just frequency counts, the table is referred to as a two-way relative frequency table " .

We are given a table or data as:

Action Drama Comedy Total

Highschool 26 14 22 62

College 20 28 18 68

------------------------------------------------------------------------------------------------------------

Total 46 42 40 128

The total number of students in all the categories and classes are: 128

Hence the two way frequency table is constructed by dividing all the frequencies by the total number of students i.e. 128.

Action Drama Comedy total

High school 26/128=0.20 14/128=0.11 22/128=0.17 0.48

Of the shirts produced by a company, 6.5% have loose threads, 9.5% have crooked stitching, and 3% have loose threads and crooked stitching. Find the probability that a randomly selected shirt has loose threads or has crooked stitching.

Answers

Answer:

[tex]P(L\ or\ C) = 0.13[/tex]

Step-by-step explanation:

Given

Represent loose threads with L, Crooked stitching with C.

So, we have:

[tex]P(L) = 6.5\%[/tex]

[tex]P(C) = 9.5\%[/tex]

[tex]P(L\ and\ C) = 3\%[/tex]

Required

Calculate P(L or C)

In probability:

[tex]P(A\ or\ B) = P(A) + P(B) - P(A\ and\ B)[/tex]

In this case:

[tex]P(L\ or\ C) = P(L) + P(C) - P(L\ and\ C)[/tex]

Substitute values for P(L), P(C) and P(L and C)

[tex]P(L\ or\ C) = 6.5\% + 9.5\% - 3\%[/tex]

[tex]P(L\ or\ C) = 13\%[/tex]

Convert to decimal

[tex]P(L\ or\ C) = 0.13[/tex]

Hence:

The required probability is 0.13

Kendall is making and selling necklaces. It costs Kendall $2.00 to make each necklace. If she sells 40 necklaces for $5.00 each, how much profit did she make?

Answers

Answer:

Kendall makes 120$ profit by selling necklaces.

Step-by-step explanation:

To show how much it costs to make all the necklaces in total multiply 2 x 40 to get 80$. To show much much money she gets for the necklaces multiply 5 x 40 to get 200$. To show how much profit she makes subtract 80$ from 200$ to get 120$.

I believe she would be making a 30$ profit bc 5x40= 90$ but 2x40 = 60$ if it costs her 60$ to make 40 bracelets we would subtract 90 from 60 which equals 30

water output rate for the Nelson family's sprinkler was 25 L per hour. The families used their sprinklers for a combined total of 60 hours, resulting in a total
water output of 1700 L. How long was each sprinkler used?
Note that the ALEKS graphing calculator can be used to make computations easier.

Answers

Answer:

We have two variables W and NW= 35 L N = 25L Total: 60 hrs respectfully between W and N Total Water: 1700 L 35W + 25N = 1700 (1)W + N = 60 (2)Just substitute!N = 60 + W 35W + 25(60 + W) = 170035 W + 1500 + 25W = 170060W + 1500 = 170060W = 200 W = 3.33 Now solve for N

A frozen yogurt shop has a combination of 150 small and medium sized bowls on their counter. Each small bowl hold 4 ounces and each medium bowl holds 6 ounces. If the bowls on the counter will hold a total of 764 ounces, find the number of small and medium sized bowls on the counter

Answers

77 small and 76 medium

The number of small sized bowls on the counter = 68 bowls

The number of medium sized bowls on the counter = 82 bowls

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of small bowls on the counter be = x

Let the number of medium bowls on the counter be = y

The total number of bowls is = 150

So , the equation will be

x + y = 150 be equation (1)

The amount the small bowl can hold = 4 ounces

The amount the medium bowl can hold = 6 ounces

The total amount of all the bowls on the counter = 764 ounces

So , the equation will be

4x + 6y = 764 be equation (2)

Now , on simplifying the equation (1) and equation (2) , we get

Multiply equation (1) by 4 , we get

4x + 4y = 600 be equation (3)

Subtracting equation (3) from equation (2) , we get

2y = 164

Divide by 2 on both sides , we get

y = 82

Therefore the number of medium sized bowl is 82 bowls

Substituting the value of y in equation (1) , we get

x + y = 150

x + 82 = 150

Subtracting 82 on both sides , we get

x = 68

Therefore , the number of small sized bowl is 68 bowls

Hence ,

The number of small sized bowls on the counter = 68 bowls

The number of medium sized bowls on the counter = 82 bowls
