Answer:
$15.75
Step-by-step explanation:
30 multiplied by 0.3 is 9. 30-9 is 21. 21 multiplied by 0.25 is 5.25. 21-5.25 is 15.75
Let x,y,z be those numbers.
x+y+z = 12
Since x,y,z are consecutive: y=x+1, and z = x+2
Let's replace y and z by their new values:
x+x+1+x+2=12
3x+3=12
You subtract 3 from each side to get variables on a side, and numbers on the other:
3x=9
You divide both sides by 3:
x=3
y=x+1 = 3+1 = 4
z=x+2 = 3+2 = 5
So the numbers are 3; 4 and 5.
You can re-check your answers (very important):
3+4+5 = 12
3;4;5 are consecutive numbers.
The answer has been approved.

Answer:
0.9958
Step-by-step explanation:
P(being correct) = 1/4 = 0.25
Hence, p = 0.25
n = 19
P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
However, to save computation time, we could use a calculator :
Using a calculator,
P(x ≥ 1) = 0.99577
P(x ≥ 1) = 0.9958
Answer:
<u><em>C) 200 cm^3
</em></u>
<u><em></em></u>
Step-by-step explanation:
we observe that
Area=20 cm² and Height=10 cm
The formula to find volume is :
Volume= Area×Height
putting the values of area and height in above formula,we get
Volume= 20 cm²×10 cm
Volume= 200 cm³
The internal volume of the container is 200 cm³.

when a negative number adds a negative number, it will be negative
when a negative number adds a positive number, whichever number (either positive or negative) take the sign of the bigger one
For example:
-4 + 3 = -1
-5 + 10 = 5
