(0,5/2)
Step-by-step explanation:
(-4 , 8) ; (4 , -3)
[tex]Midpoint = (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})\\\\=(\frac{-4 + 4}{2},\frac{8 - 3}{2})\\\\=(0 ,\frac{5}{2})[/tex]
An artist is painting a large mural of flowers on the
side of a school. If she uses the scale 4 inches = 1 inch,
how large will the mural painting of a rose bloom be if the
actual height of the rose bloom is 61 inches?
Answer:
The mural painting will be of 15.5 inches.
Step-by-step explanation:
We solve this question by proportions, using rules of three.
Scale of 4 inches = 1 inch
This means that 4 inches of real dimensions is one inch on the drawing.
How large will the mural painting of a rose bloom be if the actual height of the rose bloom is 61 inches?
The painting is a fourth of the real bloom(61 inches). So
61/4 = 15.5 inches
The mural painting will be of 15.5 inches.

What are the solutions of 2x2 + 8x + 26 = 0?
Step-by-step explanation:
2×2 + 8x + 26 =0
4 + 8x + 26 =0
4 + 26 = 0-8x
30 = 8x
divide both sides by th coefficient of x

x1 is the number of architects employed by the company.
x2 is the number of engineers employed by the company.
x3 is the number of years involved with health care projects.
x4 is the number of states in which the firm operates.
x5 is the percent of the firmâs work that is health careârelated.
Required:
a. Write out the regression equation.
b. How large is the sample? How many independent variables are there?
Answer:
y = 0.237x1 - 1.162x2 - 0.130x3 * 0.538x4 - 0.038x5 + 7.267
5 independent variables
Sample size = 48
Step-by-step explanation:
The table shows the ouorit of a multiple regression
The regression equation from the table is given by :
Coefficient = 7.267 = intercept
Predictor variables are : x1, x2, x3, x4, x5
x1 = 0.237
x2 = 1.162
x3 = 0.130
x4 = 0.538
x5 = 0.038
General form of multiple regression equation :
y = m1x1 + m2x2... + c
x1, x2,.. Are independent variables
m1, m2 = slope values of
Hence, we have ;
y = 0.237x1 - 1.162x2 - 0.130x3 * 0.538x4 - 0.038x5 + 7.267
The sample size
The number of independent variables :
x1 is the number of architects employed by the company.
x2 is the number of engineers employed by the company.
x3 is the number of years involved with health care projects.
x4 is the number of states in which the firm operates.
x5 is the percent of the firmâs work that is health careârelated.
x1, x2, x3, x4, x5 = 5 independent variables
DF Regression = k - 1
5 = k - 1 ; k = 5 +1 = 6
N - k = 42
N - 6 = 42
N = 42 + 6 = 48
Samole size = 48

Answer:
1) No. 2)No. 3)More than one, 4) Unique. 5)More than one. 6)More than one
Step-by-step explanation:
For the first two are not a triangle is because when adding the shortest two side of the triangle, it has to be longer than the longest one. 3) is because it only define 3 angles, but it can be different length, same for 5) and 6), then 4) is unique as the when defining 3 lines, it only has one combination, and the angles will be fixed.

Answer: 21
Step-by-step explanation:
A farmer borrowed $28,500 from the bank to build a new barn. The bank charges 4.5% annual simple interest and allowed the farmer to repay the loan in 42 monthly payments.
A. How much money was paid in interest?
B. How much was each monthly payment?
Answer:
A) i = $4488.75
B) Amount paid per month = $785.45
Step-by-step explanation:
A) Formula for simple interest is;
i = PRT
We are given;
Principal; P = $28500
Rate; R = 4.5% = 0.045
Time; T = 42 months = 42/12 years
Thus;
i = (28500 × 0.045 × (42/12))
i = $4488.75
B) Since interest was $4488.75 and principal is $28500,then total he paid after 42 months is;
Total = 28500 + 4488.75
Total = $32988.75
Amount paid per month = 32988.75/42 = $785.45

Which statement is true about the graph of function f?
A.
The graph has an asymptote of and is negative over the interval .
B.
The graph has an asymptote of and is positive over the interval .
C.
The graph has an asymptote of and is increasing as x approaches positive infinity.
D.
The graph has an asymptote of and is decreasing as x approaches positive infinity.
Answer:
answer D
Step-by-step explanation:
The correct statement about the graph function f(x) = log₂x is; The graph has an asymptote of x = 0 and is negative over the interval (0, 1).
What is a function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given is a function f(x) = log₂x, we need to select the correct statement from the options,
We are given the function;
f(x) = log₂x
Now, at f(0), we have;
f(x) = log₂(0)
f(x) = log 0/log 2
f(x) = -∞/0.3010
Thus, since the value is infinity, then we can say that a straight line constantly approaches the curve but does not meet at any infinite distance and as such there is an asymptote at x = 0 and it is negative over the interval (0, 1).
Hence, the correct statement about the graph function f(x) = log₂x is; The graph has an asymptote of x = 0 and is negative over the interval (0, 1).

The pie chart below represents the vehicle types owned by families. If the total number of people surveyed is 1000, approximately how many own a van?
Answer:
500 families
Step-by-step explanation:
We want to estimate the size of the dark blue section of the chart. The chart looks like the left of the pie chart is split evenly with the dark blue section. So we estimate that each of those must represent 12 or 50% of the total number of families. Therefore,
0.50⋅1000=500
About 500 families own a van.

So 1st they r saying that Stephen earns x dollars per week
And Micheal earns y dollars per week
Combining their earnings= x+y
Now, in a month we have 4.345 weeks
So, in a year(12 months) we have 52.143 weeks.. which we can round off and write it as 52 weeks
So the equation will be as follows->

Answer:
x = 40°
Step-by-step explanation:
Two sides are the same length, so the angles opposite them are the same size.
The sum of the angles = 180°. One angle is 100°, so the sum of the remaining two angles is 80°.
Since the remaining two angles are congruent, each is 40°.
