Solution :
Given :
The mean height of an American adult = 5 feet 10 inches
Therefore converting feet into inches,
We know, 1 feet = 12 inches
So, 5 feet = 5 x 12 = 60 inches
The mean height in inches = 60+10
= 70 inches
The standard deviation = 3 inches
x = 5 feet 7 inches
= 5 x 12 + 7
= 67 inches
∴ z score = 
Therefore, the man's height is 1 standard deviation below mean
Any score above greater than 3 or less than -3 is considered to be an outliner.
Here its only -1 and it is less than -3.
Therefore, the height of the man 5'7'' is not considered abnormally short.
Answer:
Mei is correct because -9 is to the left of -3 on the number line.
Step-by-step explanation:
This is because -9 is LESS than -3, when you add or subtract using negative numbers, such as 7-9, you get -2. However when you subtract 7-13, you get -6. Because you subtracted a greater number from 7, your answer is -6 is LESS than -2. This is the same with inequalities, greater negative numbers will always be smaller and smaller negative numbers will always be greater.
Hope this helps!
Only the function in C has the range of all real numbers.
Later on, when you will be familiar with more type of functions you will know that when x is on the power range is usually only positive values or negative values if only not shifted, even if shifted it will only add to its range this numbers by which unit it was shifted.
B is shifted parabola. It has the range of {y| -3≤∞}
Answer:
D) 
.
Step-by-step explanation:
Given : If the first term of the series is 30 and the 14th term is 95,
To find : what is the sum of all the terms of the series.
Solution : We have given
First term = 30 .
14 th term = 95.
Sum of all term = 
.
Here, n = 14.
.
.
.
.
Therefore, D) .
This is how you find the answer:
Divide 3.75 /2 1/2=1.5
3.75/2.5=1.5
