The formula for volume is

... V = Bh . . . . . where B is the area of the base, and h is the height

You have

... 18/35 = 2/5·h

... 18/35·5/2 = h = 9/7

The height is 9/7 units.

If you choose one student at random, what is the probability (±0.0001) that the student's score is between 20 and 30?

nordsb [41]

Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621
:
Note find probabilities from z-tables
:
Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102

-5+7q+ -5q+ -9q please help

vekshin1

For this case we must simplify the following expression

$-5 + 7q + (- 5q) + (- 9q)$

We know that, by definition:

$+ * - = -$

So, rewriting the expression we have:

$-5 + 7q-5q-9q =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major's sign is placed:

$-5 + 2q-9q =\\-5-7q$

Answer:

$-5-7q$

A ball is thrown in the air from a ledge. Its height in feet is represented by

Genrish500 [490]

check the picture below.

$\bf \stackrel{f(x)}{0}=-16(x^2-6x-7)\implies 0=x^2-6x-7 \\\\\\ 0=(x-7)(x+1)\implies x= \begin{cases} \boxed{7}\\ -1 \end{cases}$

it cannot be -1, because is a seconds amount after moving.
