I need help figuring out 121+2=9(-6-7P)+4P
Alex_Xolod [135]
Hi,


Work:


Equation;

121 + 2 = 9( - 6 - 7p) + 4p

First add up numbers and distribute 9 over parenthesis.

123  =  - 54 - 63p + 4p

Second: collect like terms.

123 =  - 54 - 59p

Move variable 59p to left side and change its sign.

59p + 123 =  - 54

Then move constant 123 to right side and change its sign.

59p  =  - 54 - 123

Calculate the difference.

59p =  - 177

Divide both sides of equation by 59.

p =  - 3


Hope this helps.

50 is one tenth of what number?
Stella [2.4K]

Answer:

500

Step-by-step explanation:

Well you find one tenth of a number by dividing it by 10

So to do the opposite, you can do 50*10 which is 500

Or if you really wanted to you could go through each option dividing them all by 10 till you got 50

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.
