Step-by-step explanation:
Answer:
Area=76.56 square feet
Step-by-step explanation:
area of a rectangle =base*height = 5ft*8ft= 40 square feet
area of a triangle=(base*height)/2 =(4ft*4ft)/2= 8 square feet
area of a square=base*height =4ft*4ft= 16 square feet
area of a circle =
* r^{2}[/tex]=3.14*
= 12.56 square feet
r = radius
Total area=(40+8+16+12.56)square feet
Total area=76.56square feet
Answer:
Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions.
Step 2 Simplify by combining like terms on each side of the inequality.
Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other.
the complete question is Pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute. The original pulse rates are measure with units of "beats per minute". What are the units of the corresponding z scores? Choose the correct choice below.
A. The z scores are measured with units of "beats per minute."
B. The z scores are measured with units of "minutes per beat."
C. The z scores are measured with units of "beats."
D. The z scores are numbers without units of measurement.
we know that
A z-score is the number of standard deviations from the mean a data point is. But more technically it’s a measure of how many standard deviations below or above the population mean a raw score is
The z scores are numbers without units of measurement
therefore
the answer is the option D
