I remember this formula for a catchy song our physic teacher showed us freshman year it's m times v So mass times velocity Song goes m times v just a little momentum....

Is this true or false 276 times 13 = 276 times 7 + 276 times 6 = 1,932 + 1,656 and why?

DIA [1.3K]

Answer:

Step-by-step explanation:

13 = 6+7

276*13 = 276*(7+6)

= 276*7 + 276 *6 {distributive property upod addition}

= 1932 + 1656

= 3588

The variable in a relation who’s value depends on the value of the independent variable is called what?

Viefleur [7K]

That is called the dependent variable. It depends upon the value of the independent variable.

f(x)=y

So we can see by inspection that the dependent variable y value depends upon the input value of the independent variable x

Any questions please feel free to ask. Thanks

What is the slope of a line perpendicular to the line whose equation is<br> 2x – 2y = 20.

Simora [160]

Answer:

-1

Step-by-step explanation:

Solve for y into y=mx+b

2x-2y=20

-2y=-2x+20

y=(-2x+20)/-2

y=x-10

the slope is m, so it’s 1

A line perpendicular to that would be -1

Test scores are normally distributed with a mean of 500. Convert the given score to a z-score, using the given standard deviatio

Bond [772]

Answer:

The percentage of students who scored below 620 is 93.32%.

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 question, we have that:

$\mu = 500, \sigma = 80$
