Complete question :
Suppose you know that the prices paid for cars are normally distributed with a MEAN or $17,000 and a STANDARD DEVIATION of $500. Use the EMPIRICAL RULE to find the percentage of buyers who paid between 15500 and 17000
Answer:
49.85%
Step-by-step explanation:
Mean = 17000
Standard deviation = 500
Obtain the Z score, which is the number of standard deviations from the mean :
((17000 - 17000) / 500) = 0
((15500 - 17000) / 500) = - 3
-3 to 3 = (3 standard deviations)
However,
The value here is (-3 to 0) ; which is only 3 standard deviations to the left.
3 standard deviation = 99.7% (empirical rule)
Since it is only (-3 to 0) ; which is only 3 standard deviations to the left. ; the percentage will be halved
99.7% / 2 = 49.85%
Hence, percentage of buyers who paid between 15500 and 17000 is 49.85%

A. 13
B. 5
C. −5
D. -13
Answer:
13
Step-by-step explanation:
g(x) = -3x + 4
g(-3) = -3 × -3+4

Christina had a total of $120 to spend while shopping. She already spent $68 on clothes . She wants to buy some video games that are on sale for $10 each, including tax.
Answer:
5 video games.
Step-by-step explanation:
In order to find the total number of video games that Tracy can buy with the money, she has we first need to find how much money she has left after buying the clothes. To do this we subtract the amount she spent on clothes by the initial total that Christina had.
120 - 68 = 52
Now that we know Christina has a remaining $52, we can divide this amount by the value of each individual game ($10) in order to calculate how many she can actually afford.
52 / 10 = 5.2
Finally, we can see that she can afford to only buy 5 video games.

A program contains the following statements: X = grade If 90: print ("You are an A student!") What action will the program take when x = 89? print "You are an A student!" print "grade - 89" print nothing print "You are a B student!"
Answer:
C. Print Nothing
Step-by-step explanation:
For those who don't wanna read
Answer:
The program is going to print nothing because the script does not tell it to say anything other than when the grade (x) is greater than 90.
Therefore,the correct option is 3, print nothing

triangle abc is similar to triangle aed
Answer:
9/5 or 1.8
Step-by-step explanation:
triangle aed is larger than triangle abc by a scale factor of 5; we know this because side ed is 5 units and cb, the corresponding side in triangle abc, is 1. if ad has a length of 9, the length of ab must be 9 divided by five. thus, z is equal to 9/5 or 1.8.
Is it possible for an isosceles triangle to have an obtuse angle of 179°? If so, what would the other two
angles have to be?
Answer:
Yes , 0.5°
Step-by-step explanation:
We know that in a isosceles triangle , two sides are equal and therefore two angles are also equal. If one of the angles is 179° then ,
⇒ 179 + 2x = 180
⇒ 2x = 180 - 179
⇒ 2x = 1
⇒ x = 0.5°
Yes it's possible to draw a isosceles triangle with one of the obtuse angles as 179° and the other angles will be 0.5° .
Yes it's possible.Can you please help meeeeeeee

what is the value of 6(2b-4) when b+5?
Answer:
The value of 6(2b-4) is 36.
Step-by-step explanation:
Given expression: 6(2b-4)
To find the value of 6(2b-4) at b=5, we need to substitute the b=5 in the expression, we get
6(2(5)-4)
= 6(10-4)
=6(6)
= 6x6=36
⇒ 6(2(5)-4)=36
Answer:
The value of 6(2b-4) when b=5 is 36.
Step-by-step explanation:
Given expression: 6(2b-4). To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get….Therefore, the value of 6(2b-4) is 36, when b=5.
Write an equation for a line perpendicular to f(x)=5x−1 and passing through the point (5,20)
Answer:
y - 20 = (-1/5)(x - 5)
Step-by-step explanation:
The slope of the given line is 5. The slope of any line perpendicular to the given line is the negative reciprocal of the given slope:
Slope of perpendicular line here is -1/5.
We use the point-slope formula as a framework here:
y - 20 = (-1/5)(x - 5)

solve for k. -5/6k = -10
Answer:
k = 12
Step-by-step explanation:
-5/6k = -10
Multiply both sides by 6k
-5/6k x 6k= -10 x6k
simplify
-5 = -60k
Switch sides
-60k = -5
Divide both sides by -60
-60k/-60 = -5/-60
Simplify to get your answer of
1/12 or 12

4. Find
A) 64.5
B) 68.5
C) 72.5
D) 76.5
Answer:
A) 64.5
Step-by-step explanation:
A circle's measurement is 360°.
It is given that arcPQ is 113° and arcQM is 118°. Subtract 113 and 118 from 360:
360 - (113 + 118) = 129°
ArcPM is 129 degrees. Note that this is a inscribed, but not a central angle. m∠PQM = (ArcPM)/2
m∠PQM = (129)/2
m∠PQM = 64.5
A) 64.5 is your answer.
