b = 58°, d = 67°
Step-by-step explanation:
*Triangle can have up to a measure of 180°*
32° + b + 90° = 180°
122° + b = 180°
b = 180° - 122°
b = 58°
23° + d + 90° = 180°
113° + d = 180°
d = 180° - 113°
d = 67°

What is unitary method?
"A method to find a single unit value from a multiple unit value and to find a multiple unit value from a single unit value."
We always count the unit or amount value first and then calculate the more or less amount value.
For this reason, this procedure is called a unified procedure.
Many set values are found by multiplying the set value by the number of sets.
A set value is obtained by dividing many set values by the number of sets.
According to our question-
Total cost = Bill before tip + Tip
Total cost = $796 + $95.52
Total cost = $891.52

No. There are y-values which map to more than 1 x-value.
Yes. Every x-value maps to exactly 1 y-value.
Answers
No, there are x values which map to more than 1 y-value.
Given that Matthew examines the relation as shown in the below.
{(4, -11), (3,1), (0,1), (2,6), (3, -1)}
We need to check whether the relation is a function or not,
So, we know that,
A relation can map inputs to multiple outputs. It is a function when it maps each input to exactly one output. The set of all functions is a subset of the set of all relations.
If any x values are repeated, and the corresponding y values are different, then we have a relation and not a function.
Here we can see that the y values are repeated, so it is not a function.

Composite shapes are made up of two or more shapes. The required volume of the composite shape in exact form is 498π cubic feet
How to calculate the volume of composite shapes?Composite shapes are made up of two or more shapes. According to the given question, the buoy is made up of a cone and sphere.
The volume of the buoy = volume of sphere + volume of the cone
Find the volume of the sphere
Vs = 4/3πr³
Vs = 4/3π(6)³
Vs = 288π cubic feet
Find the volume of the cone
Vc = 1/3πr²h
Vc = 1/3π(6)²(10)
Vc = 120π cubic feet
Volume of the buoy = 288π + 120π
V = 498π cubic feet
Therefore the required volume of the buoy in exact form is 498π cubic feet

You've developed a protein drink that you think cures arthritis. to test it, you find 200 volunteers (100 men and 100 women) and test them to measure the amount of discomfort they feel from their arthritis. then you give the treatment to half the subjects and a placebo to the others. you then test them all at regular intervals and measure their improvement. you find that the subjects who received the treatment show marked improvement. the people performing the tests are not told that they're studying an arthritis medication. you excitedly report your findings in an infomercial that is seen by millions of people, and sales skyrocket. but were the test results truly useful for determining the effectiveness of the treatment? why or why not? a. no, there was no control. b. yes, it's a blind-study. c. yes, it's a valid before-and-after design. d. can't be determined without knowing how much improvement was measured. e. no, there was no replication.
Answers
Answer:
I would say C
Step-by-step explanation:
In this experiment the subjects do not know whether they are being given the real treatment or a placebo. Also the testers do not know that treatment for arthritis has been given. The subjects being given the treatment "show marked improvement" according to the tests. Therefore this is a valid double blind experiment, making C the correct choice.

The correct answer is option (e): None of these answers is correct.
The statement "the mode is the most frequently occurring data value" is true. However, none of the options provided accurately describes the relationship between the mode and the mean.
The mode and the mean are different measures of central tendency and can have different values. There is no general rule or guarantee that the mode will always be larger or smaller than the mean. The relationship between the mode and the mean depends on the specific dataset and its distribution.

A billiard ball is struck by a cue. It travels 120 cm before ricocheting off a rail and traveling another 100 cm into a corner pocket. The angle between the path as the
ball approaches the rail and the path after it strikes the rail is 40 degrees. How far is
the corner pocket from where the cue initially struck the ball? Round your answer to the nearest centimeter.
Answers
a^2 = 100^2 + 120^2 - 2*100*120*cos(45°) where a is the distance between pocket and initial strike.
so a = sqrt(100^2 + 120^2 - 2*100*120*cos(45°))
a = 86 cm (to the nearest cm).

Lets look at the derivative part:

I need to score 172 in the 14th game to have an average of 152 in 14 games.
What is the weighted average?When the average is not of any individual rather it is an average of two or more groups or sets it is called a weighted average.
To obtain the weighted average we multiply no. of individuals by their averages and sum the next group in the previous procedure and divide them by the total no. of individuals.
The total score of 12 games is (12×150) = 1800.
Again I scored 156 is the 13th game.
Let I score 'x' in the 14th game.
∴ (1800 + 156 + x)/12 + 1 + 1 = 152.
(1800 + 156 + x)/14 = 152.
(1956 + x)/14 = 152.
1956 + x = 2128.
x = 2128 - 1956.
x = 172.
So, I need to score 172 in order to have an average of 152 for 14 games.
