What is a recession in an economy?
A recession is defined as a severe fall in economic activity that lasts more than a few episodes of time and is reflected in real GDP, income, employment, economic growth.
So if an economy is in a recession and vehicle prices drop by eight percent.
Then, we have:
= $25,295 × 8%
[tex]\mathbf{= 25295 \times \dfrac{8}{100}}[/tex]
= $2023.6
The price of a car that was previously worth 25,295 will be:
= $25295 - $2023.6
= $23271

Answer:
They spent 112 dollars on props.
The required total 16% spend on the props is $112.
Given that,
A group of friends was working on a student film that had a budget of $700. They used 16% of their budget on props. How much money did they spend on props is to be determined.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
A group of friends was working on a student film that had a budget of $700.
Budget = $700
They used 16% of their budget on props.
Total spend on the props = 700 * 16 / 100
= $ 112
Thus, the required total 16% spend on the props is $112.

A National Retail Foundation survey found households intend to spend an average of $469 during the December holiday season. Assume that the survey included 600 households and that the sample variance was $375. Calculate the margin of error for a 99% confidence interval.
Answer:
The margin of error for a 99% confidence interval. is of $2.25.
Step-by-step explanation:
We have the sample's variance, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 600 - 1 = 599
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 600 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.84.
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
In which s is the standard deviation of the sample(square root of the variance) and n is the size of the sample.
In this question:
[tex]s = \sqrt{375}, n = 600[/tex]. So, the margin of error is of:
[tex]M = 2.84\frac{\sqrt{375}}{\sqrt{600}} = 2.25[/tex]
The margin of error for a 99% confidence interval. is of $2.25.

The triangle DEF is shown in the diagram.
Find the exact value of x.
Answer:
x = 4
Step-by-step explanation:
Using cosine triangle formula, we know that;
c² = a² + b² - 2ac(cos C)
From our diagram;
a = 2x
b = x + 1
c = 7
C = 60°
Thus;
7² = (2x)² + (x + 1)² - 2(2x)(x + 1)cos 60
49 = 4x² + (x² + 2x + 1) - (4x² + 4x)(0.5)
49 = 5x² + 2x + 1 - 2x² - 2x
3x² + 1 - 49 = 0
3x² - 48 = 0
3x² = 48
x² = 48/3
x² = 16
x = √16
x = 4
the perimeter of a rectangular field is 374 yards. if the width of the field is 88 yards, what is its length
Answer:
99 yards
Step-by-step explanation:
374 - 88 = 286
286 - 88 = 198
198/2 = 99
length = 99
The required length of the given rectangular field is 99 yards.
What is a rectangle?A rectangle is a type of parallelogram having equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
Given that,
the perimeter of rectangular field is 374 yards.
And its width is 88 yards.
Suppose the length is x yards.
Since the perimeter of a rectangle is given as P= 2(l + b), where l is the length and b is the width .
Substitute the respective values to get,
374 = 2(88 + x)
=> 2x = 374 - 176
=> 2x = 198
=> x = 99
Hence, the length of the rectangular field is given as 99 yards.

y = 2x + 7
y = x + 8
Step 2: Solve for x
Substitution
Substitute in y: 2x + 7 = x + 8Subtract x on both sides: x + 7 = 8Subtract 7 on both sides: x = 1Step 3: Solve for y
Define equation: y = x + 8Substitute in x: y = 1 + 8Add: y = 9Answer:
x = 1
y = 9
Step-by-step explanation:
y = 2x + 7 --------------------(I)
y = x + 8 ----------------------(II)
Substitute y = 2x + 7 in equation (I)
2x + 7 = x + 8 {Subtract 'x' from both sides}
2x + 7 - x = 8 {Combine like terms}
x + 7 = 8 {Subtract 7 from both sides}
x = 8 -7
x = 1
Substitute x = 1 in equation (I)
y = 2*1 + 7
= 2 + 7

In a survey, respondents were asked which type of activity they enjoyed most while on vacation. The bar graph shows the responses
of males and females.
How many more males than females said that bike riding was their favorite activity?
Answer:
C. 1
Step-by-step explanation:
From the chart given, it shows that the number of makes that chose bike riding as their favorite activity are 10.
Females who chose bike riding activity are 9.
The difference between number of makes and number of makes and females who chose bike riding = 10 - 9 = 1
Therefore, this means that 1 more male than the female chose bike riding.

A sign in front of a roller coaster says you must be 40 inches tall to ride what percentage of this height is 34 inches
Answer:
85% of 40
Step-by-step explanation:
We can do this in two ways, we can either use percent proportions or use benchmark percentages. I'll do both.
So the equation for percent proportions will look something like this:
34/x = 40/100
So to solve this, we do 34*100/40, which is 3400/40 which equals 85. That means that 34 is 85% of 40 inches.
Another way to do this is to use benchmark percents:
10% of 40 is 4 and, so you do 40-4 and get 36. Then we need to get 2 more down so we do 5% of 40 which is 2, so we do 36-2 or 40-6.
Then we add up the percents which would add up to 15%, we do 100-15 and get 85%
Or we could just say, well 6 is 15% of 40 so we do 100-15 and 40-6 and get that 34 = 85% of 40
