Plot the given points:
A (‐1, 3 ), B( 8, 3), C( ‐1, 5)We see ABC is a right triangle.
Find the length of AB and AC:
AB = 8 - (-1) = 9AC = 5 - 3 = 2Find the area:
A = (1/2)bhA = (1/2)*2*9 = 9
AB:-

An automobile dealer has kept records on the customers who visited his showroom. Forty percent of the people who visited his dealership were women. Furthermore, his records show that 37% of the women who visited his dealership purchased an automobile, while 21% of the men who visited his dealership purchased an automobile.
a. What is the probability that a customer entering the showroom will buy an automobile?
b. Suppose a customer visited the showroom and purchased a car. What is the probability that the customer was a woman?
c. Suppose a customer visited the showroom but did not purchase a car. What is the probability that the customer was a man?

a.) we are looking for b
we are given
m'=.4
b|m'=.37
b|m=.21
b=b∩m+b∩m'
b∩m= (1-.4)(.21)
b∩m'=.4*.37
b= .274

A submarine dives 650 feet every 5 minutes and 5,200 feet every 40 minutes.
Answers
Answer:
Step-by-step explanation:
Answer:
feet per minute
300/2 = 6750/45 = 150 ft/minute
Since submarines dive quickly, and need to be able
to respond rapidly to sudden changes in conditions,
it is more reasonable to use feet per minute. If we work
in feet per hour at this speed we would need to convert
the data back to feet per minute in order to ensure we
don't dive too deep.
Dn = Dn-1 + 150m
where Dn is depth, Dn-1 is previous depth,
and m is number of minutes diving.

you get 17 of 22 questions correct on a math test
what is your percent of correct answers?
the lowest score to pass is 70% did you pass?
what is the minimum number of correct answers need in order to pass the test?
(pls try to explain the answer)
Answers
Answer:
77%, yes pass, at least 16
Step-by-step explanation:
so 17/22 is 0.77, convert to percentage is 77%
77% is above 70% so you passed
if you guess and check, 15/22 is 68%. since thats just a bit lower than 70%, u need at least 16 questions to pass
yw in advance :))
Answer:
a) 77% b) Yes c) 16
Step-by-step explanation:
17 out of 22 questions correct is set up as
17/22= .7727
round this number down and take it from decimal form to percentage.
.77 x 100 = 77%
You scored a 77% and you did score enough to pass.
The minimum number correct to still be able to pass is 16.
16/22 = .7273 = 73%

Dennis made an extra $245.00 for selling furniture. The extra $245.00 was 7% of the total value of the furniture he sold.
What was the total value of the furniture Dennis sold?
Answers
The total value of the furniture that was sold by Dennis is 3,500 dollars.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Dennis made an extra $245.00 for selling furniture.
Let the cost of the furniture be x.
Let the total value of the furniture be x + 245.
The extra $245.00 was 7% of the total value of the furniture he sold.
0.07(x + 245) = 245
x+ 245 = 3500
x = 3255
Then the total value of the furniture is (3,255 + 245 =) $3,500.

Step-by-step explanation:
Answer:
1/4
Step-by-step explanation:
To find the slope of a graph, use rise/run or change of y over change of x.
Just from looking at the graph, the slope has to be positive as the line is going up!
Start from the point that intersects with the line and graph. Then find another point that also intersects with the line and graph as well.
So for this graph, I am using the two points to the left.
I start from the bottom point and go up 1. Then I go to the right 4 times until I get to the second point.
Thus, the slope is 1/4!
