Answer:
option b is the correct one l
2. -11 sq rt of 112
Sq rt of 16 times sq rt of 7
Becomes 4 sq rt of 7
Multiply -11 times 4 sq rt of 7
-44 sq rt of 7
Answer A
3. Subtract 17-9 since they are hitch the same sq rt
Answer 8 sq rt of 17
The probability is 34% because 9/26=.34615384615. The first 2 numbers makes the percentage
Answer:
y=1/3x-4
Step-by-step explanation:
the slope-intercept format of the line is y=mx+b, where m is the slope and b is the y intercept.
we are given the slope (1/3) and the y intercpet (-4).
substitute the numbers into the equation
y=1/3x-4
the answer is y=1/3x-4
hope this helps!
Answer:
(E) The z-scores of the height measurements
Step-by-step explanation:
Mean is given by

Where,
n = Number of people
= The heights of people
When converting m to cm the mean would be

So, the mean would change
The median gives us the middle data value when the data values are in ascending order.
So, the median would change
Standard deviation

When converting to centimeters

Hence, the standard deviation would change
When converting to centimeters the maximum height in meters would be the maximum height in centimeters also.
The z score is given by

where,
x = Data point
= Mean
= Standard deviation
When converting to centimeters

Hence, the z score would remain the same
