Answer:

Step-by-step explanation:

you have t as a total amount of the whole class.

f= did not pass and you place the total number next to it like this; f/t represents that group. You continue this in your workings.

f/t = probability failed.

p/t = probability passed

c/t = probability completed

dc/t = probability did not complete

and draw a tree.

The random would be either of these, we know there s a possibility of 1/4 but the odds stay central. We look for a new way after this data is converted as a fraction and show these fractions as your answer.

ValentinkaMS [17]

The volume of a sphere uses the following formula:

$V = \frac{4}{3}\pi r^{3}$

Because the question asks to use 3.14 in place of pi, the formula will now look like this:

$V = (\frac{4}{3})(3.14)r^{3} = 4.18\overline{66} r^{3}$

We are given a diameter of 118 feet. The radius is half of the diameter, so divide the diameter by 2 to find the radius:

$118 \div 2 = 59$
$r = 59$

Plug this value into the formula, and solve with a calculator:

$4.18\overline{66} \times 59^3 = 4.18\overline{66} \times 205379 = 859853.413$

Although our result is one cubic foot off, the answer is <span>A. 859,852ft^3.

(859,852 is the result if the constant in the given formula is 4.18666, but the result with infinitely repeating numbers is 859,853.)</span>

Help me please im so mad :(:

Answer:

R- (-10, -3)

S- (-10, -6)

Q- (-5, -3)

P- (-5, -6)

Step-by-step explanation:

Well, Q and P would be the exact same coordinates since that land directly on the reflection line.

Basically, on this graph/question you can count how far away the vertices is from the reflection line.

For example, Point R is 5 units away from the reflection line, therefore I need to count over 5 times to the left from the reflection line for point R. (Idk if that makes sense or not, ask questions if you are confused).
