Answer: B.
Step-by-step explanation:
Let x = Number of hours the robot is performing a test run.
Given: Constant speed = 4 miles per hour
Average test run = 3 miles
Since Distance = speed x time
As per given,
(Constant speed) ( Number of hours) -(average test run) = (distance varies)
|4x-3|=1.5
Hence, the correct option is B.

Answer:
a. 0.45. , 0.54. , 5.04 is the answer
Answer:
a
Step-by-step explanation:
It's a because it starts with 0.45 (the least because if its just 45 than thats less than 54) and the greatest is 5.04 (you can think of them as 45, 54, and 504 but DON'T AVTUALLY DO THAT IN MATH).

parallelogram ABCD has the following vertices A(0,8) B(8,4) C(2,-8) D(-6,-4) is parallelogram ABCD a rectangle, and why
Answer:
Yes, because BC is perpendicular to AB, and ABCD is a parallelgram.
Yes the parallelogram is a rectangle.
What is distance formula?The distance between coordinate P(x1 , y1) and coordinate Q(x2 , y2) is calculated using the distance formula: d = √[(x2 - x1)² + (y2 - y1)²]
Given:
ABCD is parallelogram, so its opposite sides are equal in length.
i.e., AB= CD and AD= BC
Now,
d=√(8−0)²+(4−8)
d=√(8)²+(−4)²
d=√64+16
d=√80
d=√(−6−2)²+(−4−(−8))²
d=√(−8)²+(4)²
d=√64+16
d=√80
so, AB = CD
Similarly, AD= BC = √180
Hence, a quadrilateral whose opposite side are equal called as rectangle.

Answer: I say 12.5 miles
Step-by-step explanation:
Convert 26.7% to an
equivalent decimal.
Answer: 26.7
First, you must remove the percentage sign, then you will get a equivalent decimal.
When we remove the % sign, we get 26.7.
The answer is 26.7. Hope this helps!
It is found that 26.7% as an equivalent decimal is 0.267.
LEt the value of which a thing is expressed in percentage is "a' so the percent that considered thing is of "a" is b%
However percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
To convert 26.7% to an equivalent decimal, we simply divide it by 100:
26.7% ÷ 100
26.7/ 100 x 100 = 0.267
Therefore, WE can conclude that 26.7% as an equivalent decimal is 0.267.

Fill in the blank. The critical value tα/2 that corresponds to a ________% confidence level with 1000 degrees of freedom is 2.33.
Answer:
The critical value tα/2 that corresponds to a 98% confidence level with 1000 degrees of freedom is 2.33.
Step-by-step explanation:
From the question we are told that
The critical value is [tex]t_{\frac{\alpha }{2} } = 2.33[/tex]
From the student's t distribution table the probability of [tex]( t > 2.33)[/tex] at a degree of freedom of 1000 is
[tex]\frac{\alpha }{2} = (t > 2.33 ) = 0.01[/tex]
Hence the level of significance is mathematically evaluated as
[tex]\alpha = 2 * 0.01[/tex]
=> [tex]\alpha = 0.02[/tex]
Generally the confidence level is mathematically represented as
[tex]C = 1- \alpha[/tex]
=> [tex]C = 1- 0.02[/tex]
=> [tex]C = 0.98[/tex]
Converting to percentage
=> [tex]C = 0.98 * 100[/tex]
=> [tex]C = 98\%[/tex]

Step-by-step explanation:
A man earned wages of $36,300, received $2200 in interest from a savings account, and contributed $2700 to a tax-deferred retirement plan. He was entitled to a personal exemption of $4050 and a standard deduction of S6300. The interest on his home mortgage was $7800, he contributed $2900 to charity, and he paid $1750 in
state taxes. Find his gross income, adjusted gross income, and taxable income Base the taxable income on the greater of a standard deduction or an itemized
deduction
Answer:
Gross income = $38500
Adjusted gross income = $35800
Taxable income = $13000
Step-by-step explanation:
1. Gross income = wages + interest received
Gross income = $36,300 + $2200
Gross income = $38500
2. Adjusted gross income = Gross income - adjustments
Adjusted gross income = $38500 - $2700
Adjusted gross income = $35800
3. Taxable income = adjusted income - (exemption + deductions)
Taxable income = $35800 - ($4050 + $6300 + $7800 + $2900 + $1750)
Taxable income = $35800 - $22800
Taxable income = $13000
solve the following problem.
1. A leaking faucet waste about 3 liters of water a day. How many liters of water can be saved daily if 500 leaking faucets are repaired?
2. The quotient is 25 and the divisor is 14. the dividend is 353. I am the remainder what number am I?
3. Isaiah had 63 apples. He divided all apples evenly among his 9 friends. How many apples did Isaiah give to each of his friends?
4. Nancy needs 5 oranges to make a glass of orange juice. If Nancy 250 oranges, how many glasses of orange juice can she make?
Answer:
1) 1500 litres
2)Remainder = 3
3)7 apples
4)50 glasses
Step-by-step explanation:
1) We are told that a leaking faucet wastes about 3 liters of water per day.
Now, if 500 faucets are repaired, it means total number of litres saved per day = 500 × 3 = 1500 litres
2) We are told that the quotient is 25 and the divisor is 14. the dividend is 353.
Now, the quotient multiplied by the divisor should give us the dividend. Otherwise, we subtract the value we get from the dividend to get the remainder.
Thus:
Quotient × divisor = 25 × 14 = 350
This is not equal to the dividend.
Thus the remainder is;
353 - 350 = 3
Remainder = 3
3) We are told Isaiah had 63 apples.
If he divided the 63 apples among his 9 friends evenly, it means the number of apples received by each of his friends is gotten by Dividing the total number of apples by the number of friends. This gives; 63/9 = 7 apples
4) We are told Nancy needs 5 oranges to make a glass of orange juice.
Now, Nancy has 250 oranges. This means that the number of glasses of orange juice she can make is; 250/5 = 50 glasses
The town of Springville is mapped on a coordinate grid with
the origin being at City Hall. John's house is located at the
point (-5, 7) and Bill's house is located at (-2,3). How far is it
from John's house to Billy's house?
Answer:
The distance from John's house to Bill's house is 5 units
Step-by-step explanation:
John's house is located at the point (-5,7) and Bill's house is located at (-2,3) in a map of the town of Springville.
We need to find the distance from John's house to Bill's house. We use the formula of the distance between two points:
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(w-x)^2+(z-y)^2}[/tex]
Applying the formula:
[tex]d=\sqrt{(-2+5)^2+(3-7)^2}[/tex]
[tex]d=\sqrt{3^2+4^2}[/tex]
[tex]d=\sqrt{9+16}=\sqrt{25}[/tex]
d=5
The distance from John's house to Bill's house is 5 units
