Is 6/7 equal to 3/4?
zheka24 [161]
Ok so, when working to find if a fraction is equal to another you must know what it is cut down by. So 6 / 2 = 3. Now let's break down 7 by 2. It is 3.5 that is not four. So no 6/7 so not equal to 3/4.

Betsy uses 8.8 of blue paint and white paint to paint her bedroom walls. 1/4 of this amount is blue paint. And th rest is white
UNO [17]

Answer:

6.6 pints of white paint is used to paint the bedroom walls

Step-by-step explanation:

Pints of blue paint used to paint the bedroom walls = 8.8

Ratio of blue paint used = \frac{1}{4}

Therefore,

Ratio of white paint used = 1-\frac{1}{4}=\frac{3}{4}

Pints of white paint used to paint the bedroom walls = \frac{3}{4}(8.8)=3(2.2)=6.6

Therefore,

6.6 pints of white paint is used to paint the bedroom walls.

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
