Answer:

2:20

Step-by-step explanation:

This question can be answered by finding the lowest common multiple of 20 and 35, which is 140 minutes and adding this onto 12pm, or by starting at 12pm and going up in 20 minutes and 35 minutes until a matching time of 2:20pm is found.

The volume of a rectangular prism is given by the formula V=lwh, where I is the length of the prism, w is the width, and h is th

antoniya [11.8K]

Answer:

The answer is $6x^{3} +39x^{2}+54x$

Step-by-step explanation:

Volume of the rectangular prism = Length * Width * Height

Length (l) = $x+2$

Width (w) = $3x$

Height (h) = $2x+9$

By substituting these values to the equation above,

Volume of the rectangular prism = $(x+2)*3x*(2x+9)$

= $(3x^{2} +6x)*(2x+9)$

= $6x^{3} +27x^{2} +12x^{2} +54x$

= $6x^{3} +39x^{2}+54x$

Therefore,

The answer is $6x^{3} +39x^{2}+54x$

The height distribution of NBA players follows a normal distribution with a mean of 79 inches and standard deviation of 3.5 inch

Shtirlitz [24]

Answer:

The probability will be "0.0111".

Step-by-step explanation:

The given values are:

Mean,

$\mu$ = 79

Standard deviation,

$\sigma$ = 3.5

Now,

⇒ $\sigma\bar x = \frac{\sigma}{\sqrt n}$

$= \frac{3.5}{\sqrt 16}$

$=0.875$

⇒ $P(\bar x > 81) = 1 - P(\bar x < 81)$

So,

= $1 - P{\frac{(\bar x - \mu \bar x )}{ \sigma \bar x} < \frac{(81 - 79) }{0.875} ]$

= $1 - P(z < 2.2857)$

= $0.0111$

Simple...

you have:

1.) Find the slope of the line using (-2,1) and (3,6)

Using $\frac{ y_{1}- y_{2} }{ x_{1} - x_{2} }$

$\frac{1-6}{-2-3} = \frac{-5}{-5}$

m=1 (slope)

2.)Tell whether the equation, 8y+3=5x+3, is a direct variation.

y= $\frac{5x}{8}$ (None)

3.)What is the slope and y-intercept of the graph of the equation y=2x+3?

Slope =2

y-intercept=3

C.

Thus, your answer.
