A scientist reviews her data to find the measures of central tendency using a calculator. She finds the average mass of an adult

brown bear is about 1.36E5 grams, and the average mass of a beetle fly is approximately 0.61E2 grams. She also found the sum total of her data using a calculator. The total brown bear population in the world is approximately 2E5, and the total beetle fly population is approximately 7E10. Rounded to the nearest whole number, the total mass of all living beetle flies is approximately times more than the total mass of all living brown bears.
answer is 157


First, find the average mass of an adult brown bear. The average mass is about 1.36E5 grams which is equivalent to 1.36 × 105 grams in scientific notation.

The total brown bear population in the world is approximately 2E5 which is equivalent to 2 × 105 in scientific notation.

So, to find the total mass, multiply the average mass of an adult brown bear and the total number of brown bear population.



Therefore, the total mass of the brown bear population is 2.72 × 1010 grams.

Next, find the average mass of a beetle fly. The average mass is about 0.61E2 grams which is equivalent to 0.61 × 102 grams in scientific notation.

The total beetle fly population is approximately 7E10 which is equivalent to 7 × 1010 in scientific notation.

So, to find the total mass, multiply the average mass of beetle fly and the total number of beetle fly population.



Therefore, the total mass of the beetle fly population is 4.27 × 1012 grams.

Find three positive consecutive integers such that the product of the smallest and the largest is 17 more than three times the m
trapecia [35]
There are two answers to this question
the first possible answer is 5, 6, and 7 and the second possible answer is -4, -3, and -2


Step-by-step explanation:

let the three numbers be (x-1), x, and (x+1)
the product of the smallest and largest number is 17 more than 3 times the middle number, or
(x-1)(x+1) = 3x+17, or
x^2-1 = 3+17, or
x^2-3x-18 = 0
(x-6)(x+3) = 0
So x = 6 or -3
Then just subtract one and add one to get the other integers. the three numbers are 5, 6, and 7 or -4, -3, and -2
