2x-8=4(x+1). Solve for X please!
julsineya [31]

Answer:

-6 = x

Step-by-step explanation:

2x-8=4(x+1)

Distribute

2x -8 = 4x+4

Subtract 2x

2x-8-2x = 4x-2x+4

-8 = 2x+4

Subtract 4

-8-4 = 2x+4-4

-12 = 2x

Divide by 2

-12/2 = 2x/2

-6 = x

frez [133]

Answer: H_0 : \mu=50\\\\ H_1 : \mu\neq50

Step-by-step explanation:

An null hypothesis (H_0) is a statement of equality which shows that there is no statistical difference between the groups being tested.

An alternative hypothesis  (H_1) is a statement of inequality which shows that there is statistical difference between the groups being tested.

Let \mu be the population mean amount of garbage per bin .

Given : A sanitation supervisor is interested in testing to see if the mean amount of garbage per bin is different from 50.

i.e. \mu\neq 50 → Alternative

Thus , the appropriate null and alternative hypotheses :

H_0 : \mu=50\\\\ H_1 : \mu\neq50

A jet took 4 hours to fly 1800 miles against a head wind, jets speed was 525 miles per hour what was the wind speed
Ksenya-84 [330]
Well its a pretty strong wind the answer is 75 mph

First you find out the distance without the wind which is 4x525 or 2,100

Now subtract 1800 from that and you get 300

But you’re still not done because 300 is the number of miles effected by the wind in the whole flight of 4 hours.

So just divide it by 4 and you get 75. So the wind is a 75 mph wind.
