Answer:
31
Step-by-step explanation:
You divide, 372 divided by 12
the actual number of vans needed is 31 vans to accommodate the entire camp. To estimate the number of vans needed to accommodate the entire camp, we can use the concept of rounding up to the nearest whole number.
The number of vans required will be the total number of campers divided by the capacity of each van (12 passengers), rounded up to the nearest whole number.
Estimate:
Number of vans needed =[tex]\(\frac{372}{12}\)[/tex](rounded up to the nearest whole number)
[tex]\(\frac{372}{12} \approx 31\)[/tex]
So, the estimate suggests that around 31 vans will be needed to accommodate the entire camp.
To calculate the actual number of vans needed, we can use the exact division without rounding up.
Actual number:
Number of vans needed = [tex]\(\frac{372}{12} = 31\)[/tex] vans
Thus, the actual number of vans needed is 31 vans to accommodate the entire camp.

What element in the domain has image 7 in the function f(x) = x²– 2?
a. 3 b) 9 c) -1 d) 4
Answer:
[tex]f(x) = 7 \\ f(x) = {x}^{2} - 2 \\ {x}^{2} - 2 = 7 \\ {x}^{2} = 2 + 7 \\ {x}^{2} = 9 \\ x = \sqrt{9} \\ \boxed{x = 3}[/tex]

In a poll of 300 preschoolers, 125 said they preferred chocolate ice cream, 71 said they preferred vanilla, 100 said they preferred cookies & cream, and 4 said they had never eaten ice cream. If a pie chart were to be made showing the preference for each flavor, the central angle for the chocolate ice cream sector would be:_________
Find the percentage of the people who like Chocolate = chocolate/ total x 100
Percentage = 125/300 = 0.41666 x 100 = 41.6667 = 41.67 ( round as needed)
A full circle is 360 degrees.
The central angle = percentage of chocolate x 360:
0.416666 x 360 = 150
The central angle for chocolate is 150 degrees
Solve this system of equations for x using the addition method.

Which of the following is a reciprocal of 5
Hi :)
The reciprocal of 5 is 1/5.
Every number has a reciprocal except 0.
For example
5/1 is just 5 but the reciprocal of that would be 1/5.
Essentially flipping the fraction.
Answer: [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Reciprocal means the multiplicative inverse of a number. It means the numerator and the denominator which their places.
Since 5 does not have a denominator, we can keep the denominator as 1. The fraction will be [tex]\frac{5}{1}[/tex]. Now when we switch the numerator and denominator, we will get [tex]\frac{1}{5}[/tex].

There are 23 red candies, 16 blue candies,
and 10 yellow candies. What is the
probability that you will reach into the
candy bag and choose a yellow piece?
Answer:
[tex]\frac{10}{49}[/tex]
Step-by-step explanation:
There are 23 red candies, 16 blue candies and 10 yellow candies.
Which means altogether we have..
23 + 16 + 10= 49
49 candies.
To find the probability of picking a yellow piece, we know that there are 10 yellow candies out of 49 candies.
So the chances of getting a yellow piece is [tex]\frac{10}{49}[/tex]

calculus graph please help
Answer:
See Below.
Step-by-step explanation:
We are given the graph of y = f'(x) and we want to determine the characteristics of f(x).
Part A)
f is increasing whenever f' is positive and decreasing whenever f' is negative.
Hence, f is increasing for the interval:
[tex](-\infty, -2) \cup (-1, 1)\cup (3, \infty)[/tex]
And f is decreasing for the interval:
[tex]\displaystyle (-2, -1) \cup (1, 3)[/tex]
Part B)
f has a relative maximum at x = c if f' turns from positive to negative at c and a relative minimum if f' turns from negative to positive to negative at c.
f' turns from positive to negative at x = -2 and x = 1.
And f' turns from negative to positive at x = -1 and x = 3.
Hence, f has relative maximums at x = -2 and x = 1, and relative minimums at x = -1 and x = 3.
Part C)
f is concave up whenever f'' is positive and concave down whenever f'' is negative.
In other words, f is concave up whenever f' is increasing and concave down whenever f' is decreasing.
Hence, f is concave up for the interval (rounded to the nearest tenths):
[tex]\displaystyle (-1.5 , 0) \cup (2.2, \infty)[/tex]
And concave down for the interval:
[tex]\displaystyle (-\infty, -1.5) \cup (0, 2.2)[/tex]
Part D)
Points of inflections are where the concavity changes: that is, f'' changes from either positive to negative or negative to positive.
In other words, f has an inflection point wherever f' has an extremum point.
f' has extrema at (approximately) x = -1.5, 0, and 2.2.
Hence, f has inflection points at x = -1.5, 0, and 2.2.
= Introduction to elapsed time Keiko started washing at 7:28 AM and finished at 8:46 AM. How long did it take her? Give your answer in hours and minutes. min X Х o ?
Answer:
Step-by-step explanation:
At 8:28 exactly one hour had gone by.
To get to 8:46 you need to add on almost 20 minutes. which would bring it up to 8:48. Since you are 2 minutes short from :46 to :48, the correct number of minutes is 18 (48 - 2)
Answer: 1 hour and 18 minutes.
Consider f(x)=x+7 and g(x)=x^2-1 find (g of f)(x)
Answer:
g(f(x))=x^2 + 14x + 48
Step-by-step explanation:
you insert (x+7) into every x in the g(x) equation, so g(x)=(x+7)^2 - 1. then you simplify it by doing (x+7)(x+7) which gets you x^2 + 14x + 49. then you subtract the 1 from the equation to get g(f(x))=x^2 + 14x + 48.
(g o f) (x) = g ( f(x) )
= (x+7)² – 1
= x² + 14x+49 – 1
= x² + 14x+48
If you want, (f o g ) (x) below is the solution ^_^
(f o g ) (x) = f ( g(x) )
= g(x) + 7
= x²-1 +7
= x² +6
I hope I helped you^_^

Is Canada‘s population is 1/10 of the United States and Canada‘s population is 32 million how many people live in the United States
Answer:
320M
Step-by-step explanation:
It is given that Canada's population is 1/10th of the USA's population, essentially meaning that the US's population is 10x that of Canada's. Therefore, if Canada's population is 32M, multiply 10 to that:
32,000,000 x 10 = 320,000,000
320,000,000 people live in the US.
