$-3(x^{2} +5x+10)$ is the standard form of the given expression

The given expression is:

$=-3(x+3)^{2} -3+3x\\\\=-3*(x^{2} +2*3*x+3^{2} )-3+3x\\\\=-3x^{2} -3*6x-3*9-3+3x\\\\=-3x^{2} -18x-27-3+3x\\\\=-3x^{2} -15x-30\\\\=-3(x^{2} +5x+10)$

This is the standard form of the given expression.

Select all the values that cannot be probabilities a. 3/5b. 1c. -0.45d. 0.06e. 1.16f. 0g. 5/3h. √2

nikitadnepr [17]

Answer:

c,-0.45 ,

e. 1.16

g. 5/3

h. √2

Cannot be probability.

Step-by-step explanation:

Probability of any occurrence is always in the interval of 0 to 1. 0 and 1 inclusive.

0≤P(A)≤1

Any value outside this boundaries cannot be probability.

Therefore, -0.45,1.16,5/3 and √2 cannot be probability.

What is the volume of the pyramid 7x7x8

dolphi86 [110]

Answer:

The volume of the pyramid is $130\frac{2}{3}\ units^{3}$

Step-by-step explanation:

we know that

The volume of the pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the base

H is the height of the pyramid

In this problem we have a square base

$B=7^{2} =49\ units^{2}$

we have

$H=8\ units$

substitute

$V=\frac{1}{3}(49)(8)=\frac{392}{3}\ units^{3}$

Convert to mixed number

$\frac{392}{3}=\frac{390}{3}+\frac{2}{3}=130\frac{2}{3}\ units^{3}$
