Danny took a math test and got 35 correct and 10 incorrect answers. What was the percentage of the correct answers? (Round your answer the the nearest hundredth)
A student earned a grade of 80% on a math test that had20 problems. How many problems on this test did the student answer correctly? (round to the nearest whole number)
Answers
Answer:
1. 78%
2. 16
Step-by-step explanation:
35 + 10 = 45
Danny got 35/45 answers correct.
Divide 35 into 45
35 ÷ 45 = .777777778
.777777778 ≈ .78
To convert a decimal to a percentage, move the decimal point two spaces behind.
.78 = 78%
Danny got 78% of the answers correct.
80% = .8 = [tex]\frac{8}{10}[/tex]
Multiply [tex]\frac{8}{10}[/tex] by 20 to get the answer
[tex]\frac{8}{10}[/tex] × [tex]\frac{20}{1}[/tex] = [tex]\frac{160}{10}[/tex]
Simplify
[tex]\frac{160}{10}[/tex] = 16

You work for a landscaping company and need to purchase a new trailer. The original price of the model you are looking at is $1,799, but the trailer is currently on sale for 15% off.

You could also multiply .15 by $1,799, you get 269.85 (which is the discount with the sale). Subtract this value from 1799 and you would get the current price of the trailer (above)
What implications can you draw based on the coefficient of variation from these two data sets?
Summary statistics for WEIGHT and HEIGHT (both ratio variables) of American adults in different units:
Weight Height
Mean 160 pounds 66 inches
SD 30 pounds 4 inches
You cannot compare these two data sets using a coefficient of variation because they are in different units
A. That both sets of data are equally variable.
B. That the weight data is more variable than the height data.
C. That the height data is more variable than the weight data.
Answers
Answer:
B. That the weight data is more variable than the height data.
Step-by-step explanation:
Given that :
_________ Weight _____ Height
Mean ___ 160 pounds ___ 66 inches
SD _____ 30 pounds ____ 4 inches
The Coefficient of variation is the ratio of the standard deviation and mean of a particular variable.
Weight in pounds :
Standard deviation in pounds / mean in pounds
30 / 160 = 0.1875
Height in inches :
Standard deviation in inches / mean in inches
4 / 66 = 0.060
0.1875 > 0.060
Hence, weight data is more variable than height data.
PLEASE HELP ASAP PLEASE An auto-parts store offers a fuel additive that claims to increase a vehicle’s gas mileage. The additive is poured into a vehicle’s gasoline tank after the tank is filled. To measure the claim, the store offers a free bottle of the additive to customers who drive SUV's, who then provide information about their gas mileage on the store website. A customer argues that the type of vehicle could be a confounding variable in this study.
Which statement best describes the effect of the confounding variable?
Because vehicles of different sizes may respond similarly to the additive, it should be easy to conclude whether the additive improves gas mileage.
Because vehicles of different colors may show differences in gas mileage, the additive may improve the gas mileage in some vehicles but not in others.
Because owners of different types of vehicles may choose not to use the additive, those vehicles will not show an improvement in gas mileage.
Because vehicles of different sizes may respond differently to the additive, it may be difficult to conclude whether the additive improves gas mileage for all vehicles.
Answers
Answer:
Because vehicles of different sizes may respond differently to the additive, it may be difficult to conclude whether the additive improves gas mileage for all vehicles.
Step-by-step explanation:
Edge 2021
Whether the addition increases gas mileage for all vehicles may be difficult to determine.
What is sample space?The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive
Because vehicles of different sizes may respond differently to the additive, it may be difficult to conclude whether the additive improves gas mileage for all vehicles.
The type of vehicle is a confounding variable because it is related to both the independent variable (use of the fuel additive) and the dependent variable (gas mileage), and it could potentially influence the results of the study if not controlled for.
This is because the size of the vehicle, a complicating variable, may alter gas economy independently of the addition, making it challenging to assess the additive's actual impact. As a result, the study's findings might be erroneous or misleading.

Pine trees and juniper trees are common to the San Bernardino
mountains. Pine trees have a mean height of 52 meters with a
standard deviation of 3 meters. Juniper trees have a mean
height of 22 meters with a standard deviation of 5 meters.
(a) At the base of a trail, there is a 48-meter-tall pine tree and a
33-meter-tall juniper tree. Calculate the Z-score for each of
these trees.
If necessary, round your answers to the nearest 2 decimal
places. Write both answers in the text box below.
Answers
Answer:
Z-score = 0.9450
Step-by-step explanation:
Step(i):-
mean height of pine tree (x₁⁻) = 52
standard deviation of pine tree σ₁ = 3
Mean height of Jupiter tree ((x₂⁻) = 22
standard deviation of Jupiter tree σ₂ = 5
Size of first sample n₁ = 48
size of second sample n₂ = 33
Step(ii):-
Z-score
[tex]Z = \frac{x^{-} _{1} -x^{-} _{2} }{\sqrt{\frac{S.D^{2} }{n_{1} }+\frac{S.D^{2} }{n_{2} }} }[/tex]

If you are adding two positive integers, the sum will be positive.
3 + 5 = 8
If you are adding two negative integers, the sum will be negative.
-3 + (-5) = -8
If you are adding a negative integer and a positive integer, find the difference of the
absolute values. The sum will have the sign of the addend with the greater absolute value.
-3 + 5 = 2

Hours Spent Studying vs. Language Arts Test Scores
A graph has hours spent studying on the x-axis and language arts test scores on the y-axis. A line goes through points (2.5, 60) and (5, 80).
Based on trend line on the graph, what is the expected test score for a student who did not study?
0.5
8
40
45
Answers
Answer:
cccc
Step-by-step explanation:
it is correct on edge
The expected test score for a student who did not study is 40.
Option C is the correct answer.
We have,
Given that the line on the graph passes through the points (2.5, 60) and (5, 80), we can use this information to estimate the expected test score for a student who did not study.
Let's calculate the slope of the line using the two given points:
Slope = (change in y)/(change in x)
= (80 - 60)/(5 - 2.5)
= 20/2.5
= 8
The slope of the line is 8, which indicates that for every additional hour spent studying, the test score increases by 8 points.
Since we are looking for the expected test score for a student who did not study (0 hours spent studying), we can substitute x = 0 into the equation of the line to find the corresponding y value (test score).
y = mx + b (where m is the slope and b is the y-intercept)
Using the given points, we can find the y-intercept (b) by substituting one of the points into the equation:
60 = 8(2.5) + b
60 = 20 + b
b = 60 - 20
b = 40
The equation of the line is y = 8x + 40.
Now, substitute x = 0 into the equation to find the expected test score:
y = 8(0) + 40
y = 0 + 40
y = 40
Thus,
The expected test score for a student who did not study is 40.
