Answer: (d)
Step-by-step explanation:
Given
XYZA is a rhombus and side XY is 8 units
We know, In a rhombus
- All sides are equals
- Diagonals bisect each other perpendicularly
Using the above property, we can write
Thus, option (d) is correct.
F(x) = x^3-15x^2+41x-15

Answer:
Standard error = 0.83
Step-by-step explanation:
Given that the heights in inches of males in the united states are believed to be approximately normally distributed with mean u
Sample mean for 25 adults randomly taken =
inches
Std deviation of sample s = inches
Since X the height of males is Normal we find that the sample mean also will follow a normal distribution.
By central limit theorem, mean of x would be= sample mean= 69.72
Std error =
Standard error of the mean = std dev/square root of sample size.
Here only sample std deviation is known
So we used it
Standard error = 0.83
Given:
- A rectangle has a width that is 5 feet less than the length. The area of the rectangle is 126 square feet
❍Let's assume, Length of rectangle x feet and width of the rectangle x - 5 feet respectively.
To calculate the dimensions of the rectangle we will use the formula of Area of rectangle:
- We know that side can't be negative. So, x = 14 feet
Hence,
- Width of rectangle = x - 5 = 9 feet
- Length of rectangle = x = 14 feet
