Answer: 1/4 full.

Step-by-step explanation:

The question is asking for how much gas will be left in the tank after 2/3 of the gas in the tank is used.

There is currently 3/4 of the tank remaining.

To find 2/3 of 3/4, you can multiply the fractions together.

Do this by multiplying both numerators and both denominators:

\frac{2}{3} *\frac{3}{4} = \frac{2*3}{3*4} = \frac{6}{12}

Then, subtract 6/12 from 3/4. You can do this by simplifying the first fraction to 2/4 (divide both the numerator and denominator by 3).

3/4 - 2/4 = 1/4

There will be 1/4 of the tank left.

Answer:

1/4

Step-by-step explanation:

We have 3/4 of a tank

We will use 2/3 of the  gas in the tank

See the diagram  That will leave us 1/4

Mathmatically

3/4*2/3 = 2/4 =1/2  this is the amount that is used

Subtract this from the amount in the tank

3/4 -1/2

3/4 -2/4 = 1/4

This is the amount that is left in the tank

Population mean = 80
alexira [117]

Answer:

The answer is : 0.0597

Step-by-step explanation:

Population mean = μ = 80

Standard deviation = σ = 20

Sample = N = 60

σ_mean = σ/√N

= (20)/√(60) = 2.582

Now we will find z1 and z2.

z1 = {(84) - μ}/σ_mean = {(84)-(80)}/(2.582)= 1.549

z2 = {(88) - μ}/σ_mean = {(88)-(80)}/(2.582)= 3.098

Now probability that the sample mean will be between 84 and 88 is given by:

Prob{ (1.549) ≤ Z≤ (3.098) } = (0.9990) -(0.9393) = 0.0597

3*x+36=96 i give crown if you help me out
pychu [463]

Answer: x = 20

Step-by-step explanation:

Hey there! If you have any questions feel free to let me know in the comments below.

Step 1: <u>Subtract 36 from both sides.</u>

3x = 96 - 36

Step 2: <u>Simplify 96 - 36  to  60.</u>

3x = 60

Step 3: <u>Divide both sides by 3.</u>

x = 60/3

Step 4: <u>Simplify 60/3 to 20.</u>

x = 20
