find the value of x. write your answer in simplest radical form. x 9 7
Answer:
Answer B
Step-by-step explanation:
You have to use the pythagorean theorm which states that a^2+b^2=c^2
So, 7^2+x^2=9^2
49+x^2=81 subtract 49 from both sides of the equation
x^2=32
x=sqrt(32)
sqrt(32)=sqrt(16)*sqrt(2)
=4*sqrt(2)

Answer:
B. (1, 2)
Step-by-step explanation:
In a function, each value used in as an x-coordinate can be used only once.
Values already used as x-coordinates: -3, 8, 0, -5
The answer cannot have -3, 8, 0, or 5 as an x-coordinate.
The only choice without one of those four values as an x-coordinate is (1, 2).
Answer: B. (1, 2)

If sin A = cos B and the measure of angle A is 1.5 times the measure of angle B, find the measure of angle A
Answer:
[tex]A = 54[/tex]
Step-by-step explanation:
Given
[tex]\sin A = \cos B[/tex]
[tex]A=1.5B[/tex]
Required
Find A
If [tex]\sin A = \cos B[/tex]
Then:
[tex]A +B = 90[/tex]
Substitute [tex]A=1.5B[/tex] in [tex]A +B = 90[/tex]
[tex]1.5B + B = 90[/tex]
[tex]2.5B = 90[/tex]
Solve for B
[tex]B = \frac{90}{2.5}[/tex]
[tex]B = 36[/tex]
Substitute [tex]B = 36[/tex] in [tex]A=1.5B[/tex]
[tex]A = 1.5 * 36[/tex]
[tex]A = 54[/tex]

Answer:
360 cubic units
Step-by-step explanation:
height = 4 units
length = 10 units
breadth = 6 units
Volume of a cuboid = l × b × h
V = 10 × 6 × 4
V = 10 × 24
V = 240 cubic units
Now a scale factor of 1.5 units is applied to the dimensions,
new volume = 240 × 1.5 = 360
∴ New volume of the prism = 360 cubic units
Answer:
240 cubic units

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%
6) find the value of x such that the data set has the given mean
100, 121, 105, 113, 108, X ; mean = 112.
Answer:
x = 135
Step-by-step explanation:
(100 + 121 + 105 + 113 + 108 + x) /6 = 112
(547 + x) /6 = 112
547 + x = 112 × 6
547 + x = 672
x = 672 - 547
x = 135
