find the value of X
Answer:
x = [tex]\frac{91}{6}[/tex]
Step-by-step explanation:
Given 2 intersecting chords in a circle, then
The product of the parts of 1 chord is equal to the product of the parts of the other chord, that is
6x = 7 × 13 = 91 ( divide both sides by 6 )
x = [tex]\frac{91}{6}[/tex]

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
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%

If the point (a, b) is
located in Quadrant I, in which Quadrant is
the point (a, -b) located?
Answer:
Quadrant IV
Step-by-step explanation:
In Quadrant I the numbers are both positive.
In Quadrant II the number on the x-axis is negative while the number on the y-axis is positive.
In Quadrant III both numbers are negative.
In Quadrant IV the number on the x-axis in positive while the number on the y-axis is negative.
Since your plot point was (a, -b), the number in the y-axis is negative meaning it's located in Quadrant IV.

10) What is the value of x in the figure below?
Answer:
x=68
Step-by-step explanation:
let y equal the vertical angles
49+55+ y= 180
y=76
vertical angles are equal
35+76+x=180
x=68
Find the area of the given shape
find the value of x and find the value of the angle with a star in it
Answer:
x = 25
angle measure = 55
Step-by-step explanation:
The two angles are supplementary
2x+5+5x = 180
7x+5 = 180 subtract 5 from both sides
7x = 175 divide both sides by 7
x = 25 to find the angle with the star replace x with 25
25*2 + 5 = 55

0.8 k - 20 = -60
what does ‘k’ equal?
Answer:
K = -50
Step-by-step explanation:
0.8(-50) - 20 = -60, because 0.8(-50) = -40, and when you subtract a negative you would "add" those numbers. So it would be 40 + 20 = 60, which would make it -60.
Answer:
k equals -50Step-by-step explanation:
0.8 k - 20 = -60
0.8k = -60 + 20
0.8k = -0
k = [tex]\frac{-40}{0.8}[/tex]
k = -50

Angus Cut His Neighbors' Lawns For The Summer. By The End, He Had $325 In His Lawn-cutting Bank Account And He Paid A Total $75 For Gas. He Earned $10 For Ever Lawn He Mowed. How Many Lawns Did He Buy? A. N = 400 x 10 b n 250 x 10 c. N = 400 / 10 d. N = 250 / 10
Answer:
C. N = 400 / 10
Step-by-step explanation:
Lawn-cutting Bank Account = $325
Amount paid for gas = $75
Total amount earned = Lawn-cutting Bank Account + Amount paid for gas
= $325 + $75
= $400
Amount earned per every lawn he mowed = $10
How Many Lawns Did He mow?
Let N = number of lawns he mowed
N = Total amount earned / Amount earned per every lawn he mowed
N = 400 / 10
N = 40 lawns
