Question is incomplete :
Number of each type of vehicle produced isn't given :
An automobile manufacturing plant produced 32 vehicles today: 10 were sedans, 11 were vans, and 11 were trucks. Plant managers are going to choose two of these vehicles for thorough inspection. The first vehicle will be chosen at random, and then the second vehicle will be chosen at random from the remaining vehicles.
What is the probability that the first vehicle selected is a sedan and the second vehicle is a truck?
Answer:
55 / 496
Step-by-step explanation:
Total possible outcomes = 32
Number of Sedan = 10
Vans = 11
Trucks = 11
P(first selection is sedan) :
Number of sedan / total number of vehicles
= 10 /32 = 0.3125
P(second is a truck)
Total possible outcomes = 32 - 1 = 31
Number of trucks = 11 / 31
(10/32 * 11/31)
= (10*11) / (32*31)
= 110 / 992
= 55 /496

Find the 76th term on the arithmetic sequence
4, 7, 10, 13
Answer:
229
Step-by-step explanation:
1) the difference of the sequence is:
d=7-4=10-7=13-10=3.
2) the common view of the formula of the n term is:
a(n)=a(1)+d*(n-1), where n - required number of the term (it is 76), d- the calculated difference, a(1) - the 1st term of the given sequence.
3) according to the formula above it is possible to substitute n=76, d=3 and 4, then:
a(76)=4+3*(76-1)=4+225=229.
At a store, a hat has a regular price of x dollars. During sale, the price of the hat
is discounted by 20%. The expression 0.8x describes the discounted price, in dollars,
of the hat. Which expression also describes the discounted price, in dollars, of the hat?
Answer:
x - 0.2x
Since the price of the hat is labelled = x,
The percentage discount on the hat price = 20%,
Thus, the discount = 20% of the price marked
= Twenty percent of x
=0.2 x =0.2 x
Therefore, the hat's new price = Marked price - Discount
= x- 0.2 = x
Answer:
D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x

Answer:
Step-by-step explanation:
Adjacent angles when a line crosses another line must have a sum of 180 degrees.
52+2^(3x+1)=180
2^(3x+1)=128, 128=2^7 so
2^(3x+1)=2^7 which means
3x+1=7
3x=6
x=2

a. no correlation
b. positive correlation; as time passes, the CPI increases.
C.positive correlation as time passes
Answer:
B
Step-by-step explanation:
The meaning in the situation is B; positive correlation; as time passes, the CPI increases.
What does correlation coefficient convey?The correlation coefficient is the degree of association between two quantities in terms of linear relation. The range of correlation coefficient is -1 to 1
If the correlation is -1, then that refers as the one quantity increases, the other quantity decreases , also the correlation is 0, then there is no linear relationship between two variables.
There are two types of Correlation;
Positive Correlation= With Increase in x value, y value also increases, we call it positive correlation.
Negative Correlation= With Increase in x value, if y value decreases, we call it negative correlation.
As we can see from the points plotted on the graph ,with increase in x value , y value decreases.
Hence, positive correlation; as time passes, the CPI increases.

Step-by-step explanation:
A farmer sells 7.8 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market? ;)
The farmer sold 1.95 kg of apples at the farmer's market.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
Given that a farmer sells 7.8 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples.
Since 3/4 of the weight is pears, then 1/4 of the weight must be apples.
We can find 1/4 of the weight by dividing 7.8 by 4:
7.8 kg ÷ 4 = 1.95 kg
So the farmer sold 1.95 kg of apples at the farmer's market.

Determine the domain of the following graph:
Hi there! :)
[tex]\large\boxed{[-6, 6]}[/tex]
The domain of a graph consists of its x-values.
In this graph, we can see endpoints at the value x = -6 and x = 6.
Thus, the domain is from x = -6 to 6.
Since we have endpoints, however, we can use closed brackets "[]" to denote the domain in interval notation. Therefore, the domain of this function is:
[-6, 6].

the growth rate of nominal gdp between 1998 9063
and 2018 20501 was
Answer:
The nominal GDP growth rate between 1998 and 2018 was 126.20 percent.
Step-by-step explanation:
Given that in 1998 the country's GDP was $ 9,063 and in 2018 it was $ 20,501, to determine the nominal growth rate of the nation's GDP, the following calculation must be made:
9,063 = 100
20,501 = X
((20,501 x 100) / 9,063) = X
2,050,100 / 9,063 = X
226.20 = X
226.20 - 100 = 126.20
Therefore, the nominal GDP growth rate between 1998 and 2018 was 126.20 percent.

An engineer makes a model of a bridge using a scale of 0.5 cm = 3 feet. The length of the actual bridge is 123 feet. What is the length of the model?
Answer:
20.5 cm
Step-by-step explanation:
Set up a proportion where x is the length of the model in cm:
[tex]\frac{0.5}{3}[/tex] = [tex]\frac{x}{123}[/tex]
Cross multiply and solve for x:
3x = 61.5
x = 20.5
