What is (3.1 x 10^5)(2.2x10^7) in scientific notation? 5.5x10^12

6.82x10^12

5.5x10^35

6.82x10^35

Your calculator can answer this for you.

(3.1*10^5)*(2.2*10^7) = (3.1*2.2)*10^(5+7) = 6.82*10^12 . . . . . 2nd selection

(3.1*10^5)*(2.2*10^7) = (3.1*2.2)*10^(5+7) = 6.82*10^12 . . . . . 2nd selection

2.7 is less than or equal to b+5

The value of the variable b should be more than or equal to negative 2.3.

What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

2.7 is less than or equal to b + 5.

Then that can be written in mathematical form, then we have

2.7 ≤ b + 5

Then the value of b will be

b ≥ - 2.3

Then the value of the variable b should be more than or equal to negative 2.3.

More about the inequality link is given below.

Clyde Cement wants to analyze a shipment of bags of cement. He knows the weight of the bags is normally distributed so he can use the standard normal distribution. He measures the weight of 600 randomly selected bags in the shipment. Next, he calculates the mean and standard deviation of their weights. The mean is 50 lbs and the standard deviation is 1.5 lbs. What percentage of the bags of cement will weigh less than 50 lbs.?

The percentage of the bags of cement that would weigh less than 50 lbs. would be 50% because the normal distribution is symmetrical, and since the mean is your midpoint, then it would be 50% higher, and 50% lower.
