Mean:

6Mean ≠ median, not true
D.
14 - 4 = 109 - 3 = 6, 10 > 6, not trueAnswer:
B
Step-by-step explanation:
Option B is correct because from the data it's visible that all the data are around 6 miles in other words clustered. In Class A half of them are on left and half are on right. Option A is wrong because there are 17 students in class A and 18 students in class B.
Option C is wrong because the mean is 8.2 and the median is 6.
To find mean add up all the miles the students chose and divide by total students (4+4+4+4+4+5+5+5+6+6+12+13+13+13+13+14+14)/17 = 8.2
To find the median line up all the numbers and find the one in middle. It's 6.
Option D is wrong because the range for class A is (14-4)=10
and class B is (9-3)=6. So the range of class A is greater than class B.
To find range maximum value-minimum value

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
Answers
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]

Step-by-step explanation:
Answer:
[tex]a_{n}[/tex] = - 2 [tex](-3)^{n-1}[/tex]
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r = 6 ÷ - 2 = - 18 ÷ 6 = 54 ÷ - 18 = - 3
This indicates the sequence is geometric with explicit formula
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 2 and r = - 3 , then
[tex]a_{n}[/tex] = - 2 [tex](-3)^{n-1}[/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:

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
Answers
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%

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
