Answer: B
Step-by-step explanation:
There are several ways to solve this problem, but I think the easiest way is just to find the mean.
There are 12 total data points, and adding them all up you get 266.
mean = 266/12 = 22.167
The line in the middle of the box plot represents the mean, so the answer must be B.
Answer:
B

If f(x) = 3x + 2, what is f(5)?
Answer:
17
Step-by-step explanation:
f(x) is the same as y=. "What is f(5)" is the same as saying what is y=3x + 2 when x is 5.
Either way, you are going to replace x with is numerical value, which is 5, and then solve.
y = 3(5) + 2
y = 15 +2
y = 17
f(5) = 17

A toy rocket is launched vertically upward from a 8 foot platform with an
initial velocity of 120 feet per second. Its height h at time t seconds after
launch is given by the equation h(t) = -16t^2 + 120t + 8. How many seconds
until the rocket is 40 feet? (There may be more than one answer)
A) 0.28
B) 0.94
C) 3.17
D) 4.62
E) 5.98
F) 6.44
G) 7.22
H) 8.17
Answer:
We get t= 7.22 and t=0.28
The correct options are Option A and Option G
Step-by-step explanation:
The height h of toy rocket at time t seconds after launch is given by the equation [tex]h(t) = -16t^2 + 120t + 8[/tex]
We need to find how many seconds until the rocket is 40 feet?
We are given height of rocket h(t) = 40 feet
and we need to find time t
Using the equation [tex]h(t) = -16t^2 + 120t + 8[/tex] we can find time t
We have h(t)=40
[tex]h(t) = -16t^2 + 120t + 8\\Put\:h(t)=40\\40= -16t^2 + 120t + 8\\16t^2-120t-8+40=0\\16t^2-120t+32=0[/tex]
Now, we will solve the quadratic equation using quadratic formula: [tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a =16, b=-120 and c=32
Putting values and finding t
[tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-(-120)\pm\sqrt{(-120)^2-4(16)(32)}}{2(16)}\\t=\frac{120\pm\sqrt{14400-2048}}{32}\\t=\frac{120\pm\sqrt{12352}}{32}\\t=\frac{120\pm111.12}{32}\\t=\frac{120+111.12}{32}, t=\frac{120-111.12}{32}\\t=7.22\:,\:t=0.28[/tex]
So, we get t= 7.22 and t=0.28
The correct options are Option A and Option G
At every company meeting, the president speaks for 28 minutes and then takes questions from her employees. Let q represent the number of minutes she spends answering questions and t represent the total number of minutes the meeting lasts.
Answer:
t = 20 + q in minutes
Step-by-step explanation:
Company meeting = president speech + questions + answers
President speech = 20 minutes
Questions and answers = q minutes
Total time spent = t minutes
Total time spent = President speech + Total time spent
t = 20 + q
The equation that represents the relationship between q and t is
t = 20 + q in minutes
Hi, may I get some help?
Answer:
First add the number of bags. Then make sure you the percent of the total of each weight.
Step-by-step explanation:
if you rlly want to know the answer its
4+10+20+24+18+6 bags is 82
4 is 4.8 percent of 82
10 is 12.1 percent of 82
20 is 24.3 percent of 82
24 is 29.2 percent of 82
18 is 21.9 percent of 82 and
6 is 7.3 percent of 82
so answer a is 40 pounds and less
29.2+24.3+12.1+4.8=70.4 percent so its wrong
so answer b is wrong too
answer c is 29.2+21.9+7.3=58.4 so its right but we have to check d
answer d is 4.8+12.1=16.9 so its wrong
THE ANSWER IS C

The Sloan family stayed in a hotel room for 6 nights while on vacation. The total cost before tax was $1,170. If the hotel room tax rate in the city is 12%, what was the total cost for the hotel room?
Answer:
Total cost for the hotel room is $1310.4
Step-by-step explanation:
The total cost before tax was $1170.
The tax rate is 12%.
So, tax paid = 12%(1170)
Convert 12% to decimal. We get 12% as 0.12
So, tax =0.12*1170 =140.4
So, total cost for the hotel room = $140.4 +$1170 =$1310.4

Answer:
$420
Step-by-step explanation:
130x12=1560
165x12=1980
1980-1560=420
Answer:
$420
Step-by-step explanation:
The last rate was $165, and the new one is $130. To find the difference, do this equation, 165-130=?. From that equation, you get $35. As you know, there are 12 months in a year, so you multiply $35 by 12 to get $420. There is your answer.

f(x) = -222 +7
Find f(-5)
Lets solve for d.
f(x) = - 222 + 7, Find f(-5)
Step 1.
-35df2 in -222 = fx
Step 2.
-35df2 in divided by -35df2 in = fx+222 divided by -35&2 in.
d = -fx-222 divided by 35f2 in
Answer:d= - fx-222

A fish tank that holds 80 gallons of water is 55% full. How many gallons are
in the tank now? PLZ HELP
55% of the fish tank is 44 gallons.
Step-by-step explanation:To solve this, you turn the 55% into a decimal, by dividing it by 100.
55 ÷ 100 = 0.55
You then multiply the whole capacity (80) by 0.55
80 x 0.55 = 44 gallons

Answer:
[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Given the expression;
[tex](5^{\frac{3}{4} })^{\frac{2}{3} }[/tex]
Using the law of indices that states;
[tex](a^m)^n = a^{mn}[/tex]
The expression becomes;
[tex](5^{\frac{3}{4} })^{\frac{2}{3} }\\= (5^{\frac{3}{4} \times \frac{2}{3} })\\= 5^{6/12}\\= 5^{1/2}\\= \sqrt{5}[/tex]
Hence the correct answer is [tex]= \sqrt{5}[/tex]
Sam and Taylor own and operate a car wash service. Sam cleans the interior of each car and Taylor cleans the exterior. The time it takes Sam to finish the interior has a mean of 20 minutes with a standard deviation of 6.4 minutes. The time it takes Taylor to finish the exterior has a mean of 18 minutes with a standard deviation of 4.8 minutes. Both of their finishing times are approximately normally distributed.
Suppose we select a car at random, and define the random variable D as the difference between their finishing times. We can assume that their times are independent.
Find the probability that they finish within 10minutes of each other.
You may round your answer to two decimal places.
