Please help I don't get this question
Answer:
Its B.
Step-by-step explanation:
FYI you cannot completely solve the equation because there are variables
(so since we dont know what value the variables are, we cant solve the equation fully) , so the most we could do is simplify the equation.
We have to use the distributive property because there are parenthesis.
8 x 3x = 24x
and
8 x 2 y = 16y
Now just combine the answers together: 24x + 16y
Hope this helps :)
Find the 31st term of 405,397,389
Answer:
165
Step-by-step explanation:
1) the difference of the given sequence is:
d=397-405=389-397= -8.
2) common view of the formula of the 'n' term is:
a(n)=a(1)+d*(n-1), where n - required number of the given sequence, a(1) - the 1st term of the given sequence, d - the difference calculated above.
3) if to perform substitution (n=31; a(1)=405 and d= -8) into the formula above, then:
a(31)=405-8*(31-1)=405-240=165.

Two of the most popular options on a certain type of new car are automatic transmission and built-in GPS. Suppose that 90% of all buyers request automatic transmission, 82% of all buyers request built-in GPS, and 77% of all buyers request both automatic transmission and built-in GPS. Hint: It may be useful to draw Venn diagrams for these. What is the probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS
Answer:
0.95 = 95% probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS
Step-by-step explanation:
We solve this question treating these probabilities as Venn sets.
I am going to say that:
Event A: Requesting automatic transmission
Event B: Requesting built-in GPS
90% of all buyers request automatic transmission
This means that [tex]P(A) = 0.9[/tex]
82% of all buyers request built-in GPS
This means that [tex]P(B) = 0.82[/tex]
77% of all buyers request both automatic transmission and built-in GPS.
This means that [tex]P(A \cap B) = 0.77[/tex]
What is the probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS
This is [tex]P(A \cup B)[/tex], which is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
So
[tex]P(A \cup B) = 0.9 + 0.82 - 0.77 = 0.95[/tex]
0.95 = 95% probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS

A plumber charges $16 for transportation and $33 per hour for repairs.
Complete the expression that can be used to find the cost in dollars for a repair that takes h hours.
An expression that can be used to find the cost in dollars for a repair that takes h hours is
h.
Pleas Help
Answer:
16 + 33h = c

Mr. Voelz estimates that he will spend $10 on concessions at the basketball game. He actually spends $15. What is the percent error?
please
Answer:
He spent 150% than what he estimated.
Step-by-step explanation:
15 ÷ 10 = 1.5 = 150%
Answer: 66.67%
Step-by-step explanation: The first step is to divide 10 by 15 to get the answer in decimal form: 10 / 15 = 0.6667 Then, I multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.6667 * 100 = 66.67%
A whatjapanthinks.com survey asked residents of Japan to name their favorite pizza topping. The possible responses included the following choices: pig-based meats, for example, bacon or ham (PI); seafood, for example, tuna, crab, or cod roe (S); vegetables and fruits (V); poultry (PO); beef (B); and cheese (C). The following data represent the responses of a random sample of 36 people.
V PI B PI V PO S PI V S V S
PI S V V V PI S S V PI C V
V V C V S PO V PI S PI PO PI
a. Prepare a frequency distribution table.
b. Calculate the relative frequencies and percentages for all categories.
c. What percentage of the respondents mentioned vegetables and fruits, poultry, or cheese?
d. Draw a bar graph for the relative frequency distribution.
Answer:
See Explanation
Step-by-step explanation:
Solving (a):
First, we categorize each data (to get their frequencies):
PI PI PI PI PI PI PI PI PI ---> Frequency: 9
S S S S S S S S---> Frequency: 8
V V V V V V V V V V V V V ---> Frequency: 13
PO PO PO---> Frequency: 3
B ---> Frequency: 1
C C ---> Frequency: 2
Total = 36.
The frequency table is as follows:
[tex]\begin{array}{cc}{Pizza\ Topping} & {Frequency} & {Beacon\ or\ Ham} & {9} & {Seafood} & {8} \ \\ {Vegetable\ and Fruit} & {13} & {Poultry} & {3} & {Beef} & {1} & {Cheese} & {2}\ \end{array}[/tex]
Solving (b): The relative frequency and percentage.
Relative frequency is calculated by dividing each frequency by the total frequency.
So, we have:
[tex]{Beacon\ or\ Ham} = \frac{9}{36} =0.250[/tex]
[tex]Seafood = \frac{8}{36} =0.222[/tex]
[tex]Fruits\ and\ Vegetable = \frac{13}{36}=0.361[/tex]
[tex]Poultry = \frac{3}{36}=0.083[/tex]
[tex]Beef = \frac{1}{36}=0.028[/tex]
[tex]Cheese = \frac{2}{36}=0.056[/tex]
The percentage is calculated by multiplying the frequency by 100%.
So, we have:
[tex]Bacon\ or\ Ham = 0.250 * 100\% = 25.0\%[/tex]
[tex]Seafood = 0.222 * 100\% = 22.2\%[/tex]
[tex]Fruits\ and\ Vegetable= 0.361 * 100\% = 36.1\%[/tex]
[tex]Poultry = 0.083 * 100\% = 8.3\%[/tex]
[tex]Beef = 0.028 * 100\% = 2.8\%[/tex]
[tex]Cheese = 0.056 * 100\% = 5.6\%[/tex]
Solving (c): Percentage that mentioned vegetables and fruits, poultry, or cheese?.
This is calculated as:
[tex]\%Percent = Vegetable\ and\ fruits + Poultry + Cheese[/tex]
[tex]\%Percent = 36.1\% + 8.3\% + 5.6\%[/tex]
[tex]\%Percent = 50\%[/tex]
(d) See attachment for bar graph

Answer:
7x +1
Step-by-step explanation:
If A to C is 12x + 3, And A to B is 5x - 2 then you subtract the polynomials from each other!
12x- 5x = 7x
3 -2 = 1
So the answer is 7x +1!
