Answer:

b=4

Step-by-step explanation:

4b + 5 = 1 + 5b

Subtract 4b from each side

4b-4b + 5 = 1 + 5b-4b

5 =1+b

Subtract 1 from each side

5-1 = 1-1+b

4 =b

Steps to solve:

4b + 5 = 1 + 5b

~Subtract 5b to both sides

4b - 5b + 5 = 1 + 5b - 5b

~Simplify

-b + 5 = 1

~Subtract 5 to both sides

-b + 5 - 5 = 1 - 5

~Simplify

-b = -4

~Divide -1 to both sides

-b/-1 = -4/-1

~Simplify

b = 4

Best of Luck!

A submarine cuts through the water at an elevation of 203 meters under the sea. The sub rises, and the elevation changes by 4.3
mario62 [17]
The answer is -76.1 meters.

The submarine elevation before rising is -203 meters (it is negative because it is under the sea level which has 0 elevation): d₁ = -203 m
After the first rising, it moved 64.5 m: l₁ = 4.3 · 15 = 64.5 m
After the second rising, it moved 62.4 m: l₂ = 5.2 · 12 = 62.4 m

So, to calculate <span>the elevation of the submarine after rising (d</span>₂), we will add (because it is not going deeper, it rises toward the elevation of 0) two movements to the elevation before rising:
d₂ = d₁ - (l₁ + l₂) = -203 + (64.5 + 62.4) = -203 + 126.9 = -203 + 126.9 = -76.1.

I want to take a survey of students currently enrolled in my statistics course. There are 250 of them, so I number them from 001
emmasim [6.3K]

Answer:

174, 095, 148, 064, 239

Step-by-step explanation:

This is a "simple random sample" problem in which we randomly select a sample from a larger population therefore everyone has same probability of being selected.

Total students: 250

Labeled as 001, 002, 003,.....250

The generated random number table is:

69041 65817 87174 09514 8174 06423 93758 23612 17894

Now we have to arrange/sort this random number table in groups of three numbers.

690, 416, 581, 787, 174, 095, 148, 174, 064, 239, 375, 823, 612, 178, 94

Now we have to select first 5 distinct numbers in the range of 001 to 250

The first four numbers (690, 416, 581, 787) are out of range so ignore them.

Next we find our first three numbers (174, 095, 148)

Next we have number (174) again that we have already selected so ignore it.

Next we find our fourth and fifth number (064, 239)

We are done with selecting 5 numbers and these are:

174, 095, 148, 064, 239

Solve the equation by completing the square. Round to the nearest hundredth if necessary. ​x2 – 5x = 12
GuDViN [60]
X^2 - 5x = 12
x^2 - 5x + 6.25 = 12 + 6.25
(x - 2.5)^2 = 18.25
x - 2.5 = (+-) sqrt 18.25
x = 2.5 (+ - ) 4.27

x = 2.5 + 4.27 = 6.77 <==
x = 2.5 - 4.27 = -1.77 <==
