Answer:
I dont understand, what does www mean?
Step-by-step explanation:
Uhm I would appreciate the length and height so I can solve.
Remember formula of a triangle is:
BH x 1/2
OK so 8 x 12 = 96
96 divided by 23 = 32
Your answer is 32 I am pretty sure if that's the following formula of a PRISM. Please wait for more responses if needed, thank you.

o 20 is a parameter and 20.25 is a statistic.
O 20 is a parameter and 20.25 is a parameter.
Answer: 20 is a parameter and 20.25 is a statistic
Definition of parameter: a numerical characteristic of a population, as distinct from a statistic of a sample.
Definition of statistic: a fact or piece of data from a study of a large quantity of numerical data.
Hope this helps!

evaluate 4z -5y when z=8 and y=3
Answer:
17
Step-by-step explanation:
In 4z -5y, substitutte 8 for z and 3 for y, obtaining:
4(8) - 5(3) = 32 - 15 = 17
Answer:
17
Step-by-step explanation:
When you have a number by its variable you multiple, if you know the value of the variable then you multiply the two numbers together.
4z-5y
when z=8 and y=3
The equation really is
4 times 8 - 5 times 3
4 times 8 is 32
5 times 3 is 15
15-32
15-32= 17

The dimensions of a cylindrical water tank are shown below.
18 yd
60 yd

A 58,320 ya
B 3,240 yd
C 14,500 yd
D 19,440 yd
5x + 7y = 25
5x - 2y = -65
solve using elimination
(step by step please)
5x+7y=25
5x-2y=-65
subtract both of the equations
5x-5x=0
7y--2y= 7y+2y=9y
25--65=25+65=90
0+9y=90
9y=90
divide both sides by 9 to get y by itself
9y/9=90/9
cross out 9 and 9 which becomes 1*1*y=y
90/9=10
y=10
find x by using the substitution method
5x+7y=25
5x+7(10)=25
5x+70=25
move +70 to the other side
sign changes from +70 to -70
5x+70-70=25-70
5x=-45
divide both sides by 5 to get x by itself
5x/5=-45/5
cross out 5 and 5 then becomes 1*1*x=x
-45/5=-9
x=-9
answer:
(-9,10)

Answer:
A = 706.9 ft²
C = 94.2 ft
Step-by-step explanation:
A = πr²
C = πd
r = d/2 = 30 ft/2 = 15 ft
A = π × (15 ft)² = 225π ft² = 706.9 ft²
C = π × 30 ft = 30π ft = 94.2 ft

Don't mind the ones in the negative when plotting just keep them in mind and use the bigger numbers, since the scale is big
Step-by-step explanation:
When putting a negate power you just inverse the equation while keeping the power the same and only changing the sign
i.e: 4^(-3)=1/4³
