Answer:

23.12

Step-by-step explanation:

Jordan has entered 3.4 x 6.8 on his calculator.

3.4 x 6.8 = (34/10) x (68/10) = (34 x 68) / (100) = 23.12

Or an easier way would be, observing the two numbers.

In 3.4 , there is one digit after decimal point.

In 6.8 there is one digit after decimal point.

So in their product there should be two digits after the decimal point.

So the answer is <em>23.12</em>

Answer is From all those aforementioned, the true statement is: Thanh’s grade is 2.5 standard deviations below the mean of the test grades.

explanation

The z scores are standard deviations. If, for example, a tool returns a z score of +2.5, it means that the result is a standard deviation of 2.5. Very high or very low (negative) z scores associated

with very low p values are at the ends of the normal distribution.

ANTONII [103]

Answer:

The expectation of the policy until the person reaches 61 is of -$4.

Step-by-step explanation:

We have these following probabilities:

0.954 probability of a loss of $50.

1 - 0.954 = 0.046 probability of "earning" 1000 - 50 = $950.

Find the expectation of the policy until the person reaches 61.

Each outcome multiplied by it's probability, so:

E = -0.954*50 + 0.046*950 = -4

The expectation of the policy until the person reaches 61 is of -$4.
