Hey You!

Ten to the power of two = 100

So, when 42.6 is divided by 100, Sue should move the decimal 2 places to the left (before the 4).

42.6 ÷ 100 = 0.426

Answer: she will move it twice towards the left direction

Step-by-step explanation:

10 to the power of 2 is 100

42.6/100 = 0.426

Whenever you are dividing by hundred, when you shift the decimal once to the left, one of the zero will go away, when you shift the decimal again to the left the remaining zero will go away.

Fed [463]

Answer:

1.2

The first step would to be to plug in your numbers for your variables, so

ab/bc= (6)(0.9)/(0.9)(5)

(6)(0.9)/(0.9)(5)

6*0.9=5.4

0.9*5=4.5

5.4/4.5=1.2

The probability that a randomly selected score is greater than 334 will be 0.02275.

<h3>What is a normal distribution?</h3>

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The GRE is an entrance exam that many students are required to take in order to apply to graduate school. In 2014, the combined scores for the Verbal and Quantitative sections were approximately normally distributed with a mean of 310 and a standard deviation of 12.

Then the probability that a randomly selected score is greater than 334 will be

The z-score is given as

z = (x - μ)/σ

z = (334 - 310)/12

z = 24/12

z = 2

Then the probability will be

P(x > 334) = P(z > 2)

P(x > 334) = 1 - P(x<334)

P(x > 334) = 1 - 0.97725

P(x > 334) = 0.02275

More about the normal distribution link is given below.
