Answer:
(B)-4
Step-by-step explanation:
The department of motor vehicles wants to check whether drivers have a slower reaction time after drinking two cans of beer. This was done by selecting a sample of 19 drivers and randomly assigning them to one of the two groups. The reaction times (measured in seconds) in an obstacle course are measured for a group of 10 drivers who had no beer. The other group of 9 drivers were given two cans of beer each and their reaction times on the same obstacle course are measured.
What is the parameter of interest?
a. The mean reaction times (measured in seconds)
b. The mean difference in reaction times between all those who drink no beers and all those who drink two cans of beer
c. The difference between the mean reaction time of the sample of those who drink no beers and the mean reaction time of the sample of those who drink two cans of beer
d. The difference between the mean reaction time of all those who drink no beers and the mean reaction time of all those who drink two cans of beer
the area of the base is 34 cm2 the height is 7cm what is the volume
Answer:
[tex]238cm^3[/tex]
Step-by-step explanation:
The equation for volume is length x width x height
The equation for area is length x width
Since the area of the base is known, we can substitute that into the volume equation
base x height
34 x 7 = 238 cm^3

The residents of a city voted on whether to raise property taxes. The ratio of yes votes 3 to no votes was 5 to . If there were 2247 yes votes, what was the total number of votes?
Answer:
Total number of votes = 5,992
Step-by-step explanation:
Given:
Ratio of Yes and No = 3:5
Total number of yes votes = 2,247
Find:
Total number of votes
Computation:
Total number of votes = Total number of yes votes [(3+5)/3]
Total number of votes = 2,247[(8)/3]

Answer:
7 feet
Step-by-step explanation:
Answer:
A. 4ft
Step-by-step explanation:
It would be four feet because since the opening is 3ft and the length is 5ft, it would be 4ft because the length is going to be close to the height which would also be the same with the opening. The opening is always a little shorter than the top of the tent meaning this would be 4ft.

Answer:
All real numbers
Step-by-step explanation:
The domain of the function is the set of real values that can be substituted into a function to produce a valid output. Any real number can be substituted into the function (y = x), and produce a valid output. Thus, the domain is all real numbers.
When Lucas first opened his bank account, he deposited x amount of
money in there. The second week, he deposited the same amount of
money in his bank account. Two weeks later, he wrote a check for $116
and ended up having -$6 in his balance. How much money did Lucas
deposit when he first opened his account?
Answer:
55
Step-by-step explanation:
Lucas went to the bank the first time with $55 and the second time with $55, when you add those togeother you get $110. Then he wrote a check for $116 and ended up having -$6...basically if you have $110 in all then you write a check for $116 you would have -$6 in your balance. 110-116 = -6
What is the value of x?
Answer:
x = 27
Step-by-step explanation:
Based on the angle bisector theorem, we would have the following:
(x + 8)/10 = (2x - 5)/14
Cross multiply
14(x + 8) = 10(2x - 5)
14x + 112 = 20x - 50
Collect like terms
14x - 20x = -112 - 50
-6x = -162
Divide both sides by -6
-6x/-6 = -162/-6
x = 27
How many unique roots are possible in a seventh-degree polynomial

O A. 7
OB. 4
O C. 6
O D.5
Answer:
A. 7
Step-by-step explanation:
No.of unique roots are possible in a seventh-degree polynomial is 7
State fundamental theorem of AlgebraA polynomial of degree n can have at most n real roots. The Degree of Polynomial with one variable is largest power of that variable.For example, 3x^2+4x+2 = 0 have two roots since the equation degree 2.A real number p is a zero of a polynomial f(x),f(p) = 0.
Since seventh degree polynomial has degree 7, number of roots in a seventh-degree polynomial is 7.
Therefore, the number of unique roots are possible in a seventh-degree polynomial is 7.

The characteristics describe in the graph of the circle inequality are a circle with a solid boundary, center at (6, 12), and bounded solution set option first is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle equation in the inequality form:
(x – 6)² + (y – 12)² ≤ 196
The center of the circle is at (6, 12)
The radius of the circle is:
r² = 196
r = 14 units
After drawing a circle on the coordinate plane.
We will see, a circle with a solid boundary, center at (6, 12), and bounded solution set.
Thus, the characteristics describe in the graph of the circle inequality are a circle with a solid boundary, center at (6, 12), and bounded solution set option first is correct.

Henri has $24,000 invested in stocks and bonds. The amount in stocks is $6,000 more than three times the amount in bonds
Answer:
s + b = $24,000
And,
s = 3b + $6,000
Step-by-step explanation:
Let us assume the stock be s
And, the bonds be b
So according to the question
It is given that
s + b = $24,000
And,
s = 3b + $6,000
The answers are
s + b = $24,000
And,
s = 3b + $6,000

D. none of the above
Answer:
your answer will be C. rotation
Step-by-step explanation:
hope it helps...
have a great day!
The type of transformation appears to map ABC onto EFG is given by: Option B: Translation and Option C: Rotation
What is ASA congruency?If corresponding two angles and one corresponding side of two triangles are of same measurement, then the considered pair of triangles are congruent.
For this case, both the triangles ABC and EFG satisfy the ASA congruency. Thus, they are congruent. Congruent triangle means they are just same, but might be placed different or rotated.
For this case, for making ABC look like EFG, we need to rotate it, and will have to move it too(which is called translation).
Thus, the type of transformation appears to map ABC onto EFG is given by: Option B: Translation and Option C: Rotation
For some cases, we may ignore translation and just call them transformed rotationally, because usually two triangles will be placed different. But in literal sense, these two transformation will be needed for sure.

Rosa saved 40% more this month than last month. If she saved $500 this month, how much did she save last month?
Answer:
$375.14
Step-by-step explanation:
Let m represent the amount Rosa saved last month
From the question, she saved 40% more this month than last month. The total amount saved can be represented by 1.40 ( 100 + 40%)
this equation can be developed based on the information provided
1.4 x m = $500
To find m, divide both sides of the equation by 1.4
m = $500 / 1.4
m = $357.14
The Marching Band ordered 14 pizzas for a party. Each pizza had 6 slices. Juan ate 7 of the slices. How many slices were left for the rest of the band?

Given
[tex]Pizza=14[/tex]
[tex]Slice = 6[/tex] per pizza
[tex]Juan = 7\ slices[/tex]
Required
Determine the slices left
First, calculate the slices in 14 pizzas.
[tex]Total = 14 * 6[/tex]
[tex]Total = 84[/tex]
Subtract the amount eaten by Juan, to get the remaining.
[tex]Remaining = Total - Juan[/tex]

In which [tex]P(A \cup B)[/tex] is P(A or B).
