Using the method of splitting a complex shape into smaller, standard figures, find the area of Vivian’s house using only points provided in the diagram.
Answer:
Step-by-step expVivian’s house area can be split into two rectangles: FLSU and MNSR.
area of rectangle FLSU
= length × width
= (FU) × (FL)
= 30 × 25
= 750 square feet
area of rectangle MNSR
= length × width
= (MS) × (MN)
= 38 × 25
= 950 square feet
area of Vivian’s house
= area of rectangle FLSU+ area of rectangle MNSR
= 750 square feet + 950 square feet
= 1,700 square feet

A seller has a house that is 1483 square feet. The neighborhood comps show the line of
best fit to be y = 0.071x + 52.48. What is a fair price for this house? Round your answer to
the nearest thousand.
9514 1404 393
Answer:
158,000
Step-by-step explanation:
Using the given square feet for x in the equation, we have ...
y = 0.071×1483 +52.48 = 157.773
We presume this is supposed to represent the estimated value of the house in thousands.
The fair price is estimated to be 158,000.

A random sample of 35 business students required an average of 50.7 minutes to complete a statistics exam. Assume that the population standard deviation to complete the exam was 10.4 minutes. The 95% confidence interval around this sample mean is ________. Group of answer choices (48.9, 52.5) (49.8, 51.6) (47.3, 54.1) (45.4, 56.0)
Answer:
(47.3, 54.1)
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.96\frac{10.4}{\sqrt{35}} = 3.4[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 50.7 - 3.4 = 47.3
The upper end of the interval is the sample mean added to M. So it is 50.7 + 3.4 = 54.1
The answer is (47.3, 54.1).
The slope of the line shown below is 1/2

given triangle ABC if angleA=25degrees, angle B=75degrees and a=14 what is the length of side b to the nearest whole number
9514 1404 393
Answer:
b = 32
Step-by-step explanation:
The law of sines tells you ...
b = a·sin(B)/sin(A)
b = 14·sin(75°)/sin(25°) ≈ 31.998

If the volume of a hemisphere is 92160 pie cubic cm then find
its radius.
Answer:
radius = 51.70 cm
Step-by-step explanation:
Volume = (2/3) π r³
Volume = 92160 π
Radius = ?
Using the above formula
V = (2/3) π r³
r³ = v/((2/3) π)
r³ = ((92160 π) x 3) / (2 x π)
r³ = 276480/2 because (π/π) = 1
r³ = 138240
Taking cube root on both sides
r = 51.70 cm

Whitus v. Georgia In the classic legal case of Whitus v. Georgia, a jury pool of 90 people was supposed to be randomly selected from a population in which 27% were minorities. Among the 90 people selected, 7 were minorities. Find the probability of getting 7 or fewer minorities if the jury pool was randomly selected. Is the result of 7 m
Answer:
0.000004 = 0.0004% probability of getting 7 or fewer minorities if the jury pool was randomly selected.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either it was a minority, or it was not. The probability of a person being a minority is independent of any other person. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Jury of 90 people:
This means that [tex]n = 90[/tex]
27% were minorities.
This means that [tex]p = 0.27[/tex]
Find the probability of getting 7 or fewer minorities if the jury pool was randomly selected.
This is:
[tex]P(X \leq 7) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) + P(X = 7)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{90,0}.(0.27)^{0}.(0.73)^{90} \approx 0[/tex]
[tex]P(X = 1) = C_{90,1}.(0.27)^{1}.(0.73)^{89} \approx 0[/tex]
[tex]P(X = 2) = C_{90,2}.(0.27)^{2}.(0.73)^{88} \approx 0[/tex]
[tex]P(X = 3) = C_{90,3}.(0.27)^{3}.(0.73)^{87} \approx 0[/tex]
[tex]P(X = 4) = C_{90,4}.(0.27)^{4}.(0.73)^{86} \approx 0[/tex]
[tex]P(X = 5) = C_{90,5}.(0.27)^{5}.(0.73)^{85} \approx 0[/tex]
[tex]P(X = 6) = C_{90,6}.(0.27)^{6}.(0.73)^{84} \approx 0[/tex]
[tex]P(X = 7) = C_{90,7}.(0.27)^{7}.(0.73)^{83} = 0.000004[/tex]
So
[tex]P(X \leq 7) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) + P(X = 7) = 7*0 + 0.000004[/tex]
0.000004 = 0.0004% probability of getting 7 or fewer minorities if the jury pool was randomly selected.

Step-by-step explanation:
Phil has completed 1/4 of his shift; Darren has completed 3/7 of his shift; Alice has finished 1/8 of her shift; Lisa has 1/5 of her shift remaining. Out of the four employees, who has completed the least work time?
Answer:
Out of the four employees, Alice is the one who has completed the least work time, since she only completed 12.5% of it.
Step-by-step explanation:
Since Phil has completed 1/4 of his shift; Darren has completed 3/7 of his shift; Alice has finished 1/8 of her shift of her; and Lisa has 1/5 of her shift remaining, to determine, out of the four employees, who has completed the least work time, the following calculation must be performed:
Phil: 4 - 1/4 = 3/4 = 0.75
Darren: 7 - 3/7 = 4/7 = 0.57
Alice: 8 - 1/8 = 7/8 = 0.875
Smooth: 5 - 1/5 = 4/5 = 0.8
Thus, of the four employees, Alice is the one who has completed the least work time, since she only completed 12.5% of it.

Step-by-step explanation:
Hello There!
If you didn't know the exterior angle of a triangle is equal to the opposite interior angles
so

subtract 68
100-68=32
68-68 cancels out
we're left with
x = 32
the top fully says solve the following system of equations. please help!!
Answer:
x = - 4, y = - 1
Step-by-step explanation:
Given the 2 equations
3x + 7y = - 19 → (1)
7x - 4y = - 24 → (2)
Multiplying (1) by 4 and (2) by 7 , then adding will eliminate the y- term
12x + 28y = - 76 → (3)
49x - 28y = - 168 → (4)
Add (3) and (4) term by term to eliminate x
61x + 0 = - 244
61x = - 244 ( divide both sides by 61 )
x = - 4
Substitute x = - 4 into either of the 2 equations and solve for y
Substituting into (1)
3(- 4) + 7y = - 19
- 12 + 7y = - 19 ( add 12 to both sides )
7y = - 7 ( divide both sides by 7 )
y = - 1
Solve the equation In (x-4)=1
Answer:
The answer is x = 5
Step-by-step explanation:
1) Remove parentheses.
[tex]x - 4 - 1[/tex]
2) Add 4 to both sides.
[tex]x = 1 + 4[/tex]
3) Simplify 1 + 4 to 5.
[tex]x = 5[/tex]
Therefor, the answer is x = 5.
Answer:
X = 5
Step-by-step explanation:
This is an example of a basic algebraic equation! The explanation is below
[tex](x-4)=1\\x-4=1\\x-4+4=1+4\\x=5[/tex]
Above, we simply removed the parenthesis, added four to both sides in order to cancel out "-4", and ended up with 5 = x. We know we are correct because 5 minus 4, really does equal one!
