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$.
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%

Angle Relationships
Answers
Answer:
In Geometry, there are five fundamental angle pair relationships:
Complementary Angles.
Supplementary Angles.
Adjacent Angles.
Linear Pair.
Vertical Angles.
The measure of the angle u and angle t will be 29 degrees.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The angle u is congruent to angle t.
From the diagram, angle t, angle u, and angle 122 are supplementary angles. Then the equation is given as,
∠t + ∠u + 122° = 180°
∠t + ∠t = 58°
2∠t = 58°
∠t = 29°
The measure of the angle u and angle t will be 29 degrees.

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

Solve x and y 3x-4y=18,9x-2y=12
Answers
Answer:
3x-4y=18
1xy=18
xy=18 ans
Answer:
X=2/5
Y=-21/5
Step-by-step explanation:
solve your system by substitution.
3x−4y=18;9x−2y=12
Step: Solve3x−4y=18for x:
3x−4y=18
3x−4y+4y=18+4y(Add 4y to both sides)
3x=4y+18
3x/3=4y+18/3
(Divide both sides by 3)
x=4/3y+6
Step: Substitute 4/3y+6 for x in 9x −2y=12:
9(4/3y+6)−2y=12
10y+54=12(Simplify both sides of the equation)
10y+54+−54=12+−54(Add -54 to both sides)
10y=−42
10y/10=-42/10 . (Divide both sides by 10)
y=-21/5
Step: Substitute
21/5 fory in x= 4/3y+6
x= 4/3y (-21/5) +6
X=2/5 (Simplify both sides of the equation)
Answer:
X=2/5
Y=-21/5

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
