Stephen Curry's record during the 2017 - 2018 NBA final game is made up of 2-point shots and 3-points.

grandymaker [24]

Answer:

x = 12 ( two points shots )

y = 7 ( three points shots )

Step-by-step explanation:

Let´s call "x" two points shots, and "y" three points shots, then

x + y = 19

2*x + 3*y = 45

We have to solve a two-equation system for x and y

y = 19 - x

2*x + 3 * ( 19 - x ) = 45

2*x + 57 - 3*x = 45

- x = 45 - 57

-x = - 12

x = 12

And y = 19 - 12

y = 7

Normal Distribution. Cherry trees in a certain orchard have heights that are normally distributed with mu = 112 inches and sigma

Lubov Fominskaja [6]

Answer:

The probability that a randomly chosen tree is greater than 140 inches is 0.0228.

Step-by-step explanation:

Given : Cherry trees in a certain orchard have heights that are normally distributed with $\mu = 112$ inches and $\sigma = 14$ inches.

To find : What is the probability that a randomly chosen tree is greater than 140 inches?

Solution :

Mean - $\mu = 112$ inches

Standard deviation - $\sigma = 14$ inches

The z-score formula is given by, $Z=\frac{x-\mu}{\sigma}$

Now,

$P(X>140)=P(\frac{x-\mu}{\sigma}>\frac{140-\mu}{\sigma})$

$P(X>140)=P(Z>\frac{140-112}{14})$

$P(X>140)=P(Z>\frac{28}{14})$

$P(X>140)=P(Z>2)$

$P(X>140)=1-P(Z$

The Z-score value we get is from the Z-table,

$P(X>140)=1-0.9772$

$P(X>140)=0.0228$

Therefore, the probability that a randomly chosen tree is greater than 140 inches is 0.0228.
