In this case we have a uniform probability. In the graph the horizontal axis represents the possible values of the variable x and the vertical axis represents the probability P(x).

To calculate the probability that x is between 4.71 and 7.4 we calculate the area under the curve.

The horizontal length between 4.71 and 7.4 is:

$7.4-4.1 = 3.3$ .

Then notice that the vertical length in this interval is 0.125.

Then the area of a rectangle is:

$A = lw$

Where l is the length and w is the width.

In this case we have to:

$l = 3.3$

$w = 0.125$

$P = A = 3.3 * 0.125$

$P=0.4125$

1/6m=5/8<br> i can't slove this question<br> 8th Grade Math

murzikaleks [220]

we are given

$\frac{1}{6} m=\frac{5}{8}$

Since, we have to solve for m

so, we will try to isolate m on anyone side

so, firstly , we will get rid of 1/6

so, we can multiply both sides by 6

$6*\frac{1}{6} m=6*\frac{5}{8}$

$m=6*\frac{5}{8}$

now, we can simplify right side

$m=3*\frac{5}{4}$

now, we can multiply them

and we get

$m=\frac{15}{4}$ ...........Answer
