What fraction of 3 is 2 2/5

Yuki888 [10]

Answer: 2 2/5 is 4/5 of 3

Step-by-step explanation:

We can view that as what do we multiply 3 by to get 2 2/5 and call that value x

3x = 2 2/5

x = (2 2/5)/3

Let's turn 2 2/5 into an improper fraction... 2 2/5 = 12/5

So we have

x = (12/5)/3 = (12/5)(1/3) = 4/5

Thus 2 2/5 is 4/5 of 3

Verify: 3(4/5) = 12/5 = 2 2/5

Write an equation of the parabola that passes through the point (62,-490) and has x-intercepts -8 and 72

bixtya [17]

Step-by-step explanation:

as x intercepts are -8 and 72 we realize that f(x)=a(x+8)(x-72)

we know that f(62)=-490 so a= -0.7

so f(x)= -0.7(x+8)(x-72)

Elevator Safety Example 2 referred to an elevator with a maximum capacity of 4000 lb. When rating elevators, it is common to use

MrRa [10]

Answer:

0.7019; no, it does not appear to be safe.

Step-by-step explanation:

We want to find P(X > 185). However, in a z table, we are given the area under the curve to the left of the value; this means we want to find

1 - P(X ≤ 185)

The z score for the mean of a sample is given by

$z=\frac{\bar{X}-\mu}{\sigma \div \sqrt{n}}$

For this situation, the mean, μ, is 189 and the standard deviation, σ, is 39. Our sample size, n, is 27. This gives us

z = (185-189)/(39÷√27) = -4/(39÷5.1962) = -4/7.5055 = -0.53

Using a z table, we see that the area under the curve to the left of this value is 0.2981. This means our probability is

1-0.2981 = 0.7019.
