-30
Step-by-step explanation:
In g(8) the 8 = n. So, substitute 8 in for n in the expression -4n + 2
g(8) = -4(8) + 2 = -32 + 2 = -30
Answer:
-30
Steps:
For this you just have to replace the "n" with the 8. make sure you put it parentasies.
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

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%

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.
Help would be much appreciated

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
Step-by-step explanation:
16 dollars is the bare minimum, plus an additional 33 dollars every hour. If hours are represented by h and the cost is represented by c, we see that:
16 + 33h = c

How do I find the density? Harold is a woodworker and is interested in finding the density of two different types of wood. He bought a pine log that has a 5-inch radius and is 30 inches long. The weight of the log is approximately 42.63 pounds.
Answer:
The density of the pine log is 0.2842 pounds per inch.
Step-by-step explanation:
To calculate the density of an object, you must divide its mass by its volume (radius times height). Thus, given that the pine log that has a 5-inch radius and is 30 inches long, while its weight is approximately 42.63 pounds, the following calculation must be performed to determine its density:
X = 42.63 / (30 x 5)
X = 42.63 / 150
X = 0.2842
Thus, the density of the pine log is 0.2842 pounds per inch.
Each circle counts as one whole. Write a mixed number giving the amount shaded. Then, write this amount as an improper fraction.
