Answer:
264,000 (D)
Step-by-step explanation:
An average of 2000 products is produced per month.
In 2005, the company produced 2000*12 = 24000 products
The total amount of products produced between 2005 to 2008 if the company produces X products from 2006 to 2008 is
X + 24000
The average = (X + 24000)/4
The average is 200% higher than that in 2006
24000 + 200%(24000)
= 24000 + 48000
= 72,000
Therefore;
(X + 24000)/ 4= 72000
X + 24000 = 72000 * 4
X + 24000 = 288000
X = 288000 - 24000
X = 264000 (D)
Answer: x=9,y=-1/3
Step-by-step explanation: This is for Q. 16
Rearrange terms to line up properly.
x-3y=10
x+3y=8
eliminate y terms
x=10
x=8 now add all like terms, remember it's a given that there's a one in
front of a variable.
2x=18 solve for x
x=9 now plug in the nine into one of the original eq.s and solve for y
9+3y=8
3y=-1
y=-1/3 always check solutions in both eq.s to vertify. they both work
Answer:
x^3 +3x^2 +6x
Step-by-step explanation:
Eliminate parentheses using the distributive property. Collect terms. Standard form has the exponents decreasing.
= 8x -6x^3 +5x^2 -2x^2 -2x +7x^3
= x^3(-6 +7) +x^2(5 -2) +x(8 -2)
= x^3 +3x^2 +6x
Answer:
the probability that the average diameter of those sand dollars is more than 4.73 centimeters is 0.5910
Step-by-step explanation:
Given information:
mean, x = 5
standard deviation, σ = 0.9
number of sample, n = 16
now we calculate the probability that the average diameter of those sand dollars is more than 4.73 centimeters.
P(x>4.73) = P (z > (4.73 - x) / (σ
)
= P (z > (4.73 - 4) / (0.9
)
= P (z > 0.203)
= 0.5910
