Answer:
Option B, C and E are supplementary angles.
Step-by-step explanation:
We need to find supplementary angles.
Supplementary angles are those angles who sum up to 180 °.
I have attached picture for reference.
Looking at the figure given:
We have supplementary angles:
∠4 and ∠3∠4 and ∠5∠5 and ∠6∠7 and ∠8∠3 and ∠6But the options given are: ∠4 and ∠3,∠4 and ∠5, ∠3 and ∠6
So, Option B, C and E are supplementary angles.
The angle pairs that are supplementary are <4 and 3, <4 and 5 and <3 and <6.
What are supplementary angles?A supplementary angle is an angle that add up to 180 degrees. For example 100 and 80 degrees are supplementary angles.

A researcher wants to determine if college students typically drink more than 3 times per week. She collects data on 125 college students. From the sample, she finds that they drank an average of 3.5 times per week, with a standard deviation of 2.3 drinks. Use a 5% significance level for any testing. Based on the scenario above, which of the following is TRUE regarding the type of test that would need to be performed?
a. It is a two-tailed test.
b. It must be completed using the critical value approach.
c. It is a one-tailed test.
d. We reject the null and prove our claim.
e. We would need to estimate the significance level from the data.
f. Hypothesis testing cannot be performed on percentages.
Answer:
C: It is a one-tailed test.
Step-by-step explanation:
We are told the researcher wants to determine if college students typically drink more than 3 times per week.
This means the null hypothesis is;
H0: μ ≥ 3
this indicates that it's a one tailed test as the null hypothesis is only to the right side of 3 and thus just one tail.
This question will be solved using p-value approach since we are given population mean, sample mean, sample size and standard deviation.
We can't reject the null without finding out the p-value and seeing if it is less than the significance value given.
Hypothesis testing can be done done proportions or percentages.
Thus, the correct option is one-tailed test.

What’s the surface area in square units if right I’ll mark brainleiest
Answer: 349 square units
============================================
Work Shown:
L = 5.5 = lengthW = 5 = widthH = 14 = heightSA = surface area of rectangular prism
SA = 2*(L*W + L*H + W*H)
SA = 2*(5.5*5 + 5.5*14 + 5*14)
SA = 2*(27.5 + 77 + 70)
SA = 2*(174.5)
SA = 349
The surface area is 349 square units.

Twice a number increased by 43 is greater than one-fourth the number increased by 88. Which inequality can be used to determine the number?
2x + 43 > 4x + 88
2x+43>x/4+88
2x+43>x/4-88
2x+43
The required inequality is given as 2x + 43 > x/4 + 88. Option B is correct.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Let the number be x,
According to the question,
Twice a number increased by 43 is greater than one-fourth the number increased by 88.
2x + 43 > x/4 + 88
Thus, the required inequality is given as 2x + 43 > x/4 + 88. Option B is correct.

Jane and five friends go on a camping holiday together for a week,
The 6 friends will share the costs of the holiday equally.
Here are the costs of the holiday.
£216 for 6 return coach tickets
£404 for the campsite
£316 for hire of a tent for a week
Work out how much Jane has to pay for her share of the costs.
Answer:
Jane's share of the cost is £156
Step-by-step explanation:
Since the cost is to be shared equally amongst the 6 friends, to get the amount to be paid by Jane, we must work out the total cost to be incurred first.
Total cost = £216 + £404 + £316
= £936
Since there are 6 friends willing to bear this cost equally, the amount to be paid by Jane
= £936/6
= £156

1) All cars are blue. (2) All pigs have wings. Therefore, (3) All buses have three wheels. Question 2 options: Passes the true premises test and passes the proper form test. Passes the true premises test and fails the proper form test. Fails the true premises test and passes the proper form test. Fails the true premises test and fails the proper form test. None of the above.
Answer:
Fails the true premises test and fails the proper form test
Explanation:
A valid argument must pass the true premises test and the proper form test.
True premises test checks to see if what the premises is saying is true about the world, example- pigs do not have wings and so the argument fails the true premises test. Proper form test assumes the premises is true and then checks to see if a valid conclusion was drawn based on the premises(even though it might fail the true premises test and may not be true about the world)

Answer:
The median is 6
Step-by-step explanation:
First put the numbers in order: 3,4,4,4,5,7,7,8,9,12
Here, the 5th & 6th terms are 5 &7
So, median = 5+7/2
=12/2
=6
Answer:
6
Step-by-step explanation:
For funding out the median firstly we need to arrange the data in ascending or descending order . Here on arranging the given data in ascending order we have ,
3,4,4,4,5,7,7,8,9,12The median is the middle most observation , in case of odd nos . And the mean of two middlemost observations in case of even nos . Here the number of data is even , and the two middlemost observations are 5 and 7 , so ,
=> Median = x₁ + x₂ / 2
=> Median = 5 + 7/2
=> Median = 12/2
=> Median = 6
Hence the median of the given data is 6 .Plz I will give brainliest
