The lateral area of a right pyramid can be calculated by multiplying half of the perimeter of the base by the slant height. This is summarized by the formula: LA 5 Ps. We can relate this formula to the square pyramid below and its net. The side length of the base of the pyramid is b, and the slant height is s.
Answer:E
Step-by-step explanation:
The margin of error of 1.5 years indicates that we are confident the population mean age is captured i. The interval 26-1.5=24.5 to 26+1.5=27.5 years old. Therefore, it is plausible that the average age of first time mothers is 27 years old.
Length x width x height, 12 x 5 = 60, multiplied by 2 1/4 = 540. if it’s the fractions thats confusing you, to turn a fraction into a decimal you multiply the whole number by the denominator, then add the numerator.
1/2=5/10
1/5=2/10
1/2+1/5
=5/10+2/10
=7/10
So your answer is 7/10
