3(b+2) divided by 2 equal 4b-10 divided dy 4

Gwar [14]

Answer:

b=-11

Step-by-step explanation:

I assume you are looking to solve for the value of b.

3(b+2) x 2= 4b-10

2 2 4

6(b+2) = 4b-10

4 4

x 4 x4

6(b+2) = 4b-10

6b+12=4b-10

-4b -4b

2b+12=-10

-12 -12

2b=-22

If random samples of size 11 are drawn from a population with mean 7 and standard deviation 3 , find the standard error of the d

allsm [11]

Here,

n = 11

mean = 7

Standard Deviation (σ) = 3

S.E. = ?

We know that,

S.E. = σ/ $\sqrt{n}$

S.E. = 3/ $\sqrt{11}$

∴ S.E. = 0.905 Ans.

Solve the equation. x+7=−8

dimulka [17.4K]

X+7=-8
You are trying to get x on its own so you will subtract 7 from both sides.
x+7-7=-8-7
This simplifies to x= -8-7
A negative plus a negative equals a negative. So -8-7 equals -15
Your final answer is x=-15
