Like terms are either CONSTANTS, or they are terms with the same VARIABLE that have the same EXPONENT. Some examples: 9x and 5x are like terms because they both have the same variable (x) with the same exponent (1). however, 5 and 5x are not like terms, because one is a constant while the other has a variable. hope this helps you out

Suppose you can somehow choose two people at random who took the SAT in 2014. A reminder that scores were Normally distributed w
Sindrei [870]

Answer:

22.29% probability that both of them scored above a 1520

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 1497, \sigma = 322

The first step to solve the question is find the probability that a student has of scoring above 1520, which is 1 subtracted by the pvalue of Z when X = 1520.

So

Z = \frac{X - \mu}{\sigma}

Z = \frac{1520 - 1497}{322}

Z = 0.07

Z = 0.07 has a pvalue of 0.5279

1 - 0.5279 = 0.4721

Each students has a 0.4721 probability of scoring above 1520.

What is the probability that both of them scored above a 1520?

Each students has a 0.4721 probability of scoring above 1520. So

P = 0.4721*0.4721 = 0.2229

22.29% probability that both of them scored above a 1520

Name one possible cross section of a sphere
Lisa [10]
A "cross section" is basically the two-dimensional face that you get when you cut a three-dimensional figure a certain way.  For example, imagine you're buttering your bread.  When you cut a pat of butter off, what shape is left on the butter?  A square!

So, imagine cutting a ball in half.  What shape is left?  A circle!

Answer: circle
