6+2[x+8]+3x+11+x help plzzzzz

1 answer:

6+2(x+8)+3x+11+x
First you have to expand the brackets:
6+2x+16+3x+11+x
Now you group like terms (terms with the same or no variable):
2x+3x+x+11+16+6
And finally, combine like terms:
6x+33

Hope this helps :)

What types of lines are coplanar and intersect at a right angle?

Aleonysh [2.5K]

Answer: hope this help's

Step-by-step explanation:

Geometry Terms Chapter 3

A B

Coplanar in the same plane

Parallel lines coplanar lines that do not intersect

Intersecting lines coplanar lines that have exactly one point in common

Perpendicular lines lines that intersect at righ- are non-coplanar

- they are not parallel and do not intersect

t angles are non-coplanar

- they are not parallel and do not intersect

- planes that do not intersect - two segments are parallel if the lines containing them are parallel - a line that intersects two or more coplanar lines at different points

- transversal has nothing to do with whether lines are parallel or not - an angle formed between parallel lines by a third line that intersects them

lie on the same side of the transversal and in corresponding positions

alternate exterior angles

- non-adjacent exterior angles that lie on opposite sides of the transversal

10/56 hope this help you a lot better

The probabilities that a batch of 4 computers will contain 0, 1, 2, 3, and 4 defective computers are 0.4521, 0.3970, 0.1307, 0.0

Answer:

The standard deviation of given probability distribution is 0.767.

Step-by-step explanation:

We are given the following information in the question:

X: 0 1 2 3 4

P(x): 0.4521 0.3970 0.1307 0.0191 0.0010

Formula:

$\text{Mean} = \sum X.P(x)\\= 0(0.4521) + 1(0.3970) + 2(0.1307) + 3(0.0191) + 4(0.0010)\\= 0.7197$

$\mu = 0.7197$

Formula:

$\text{Variance} = \sum (X-\mu)^2E(x)\\= (0-0.7197)^2(0.4521)+(1-0.7197)^2(0.3970)+(2-0.7197)^2(0.1307)+(3-0.7197)^2(0.0191)+(4-0.7197)^2(0.0010) \\=0.587$

$\text{Standard Deviation} = \sqrt{\text{Variance}}\\= \sqrt{0.587} = 0.767$

The standard deviation of given probability distribution is 0.767.
