A company installs a rectangular septic tank 30 ft long by 15 ft wide and 2 ft deep. Calculate the capacity of the tank in gallons. (Use 1ft3 = 7.48 gal.)
Answer:
V = lwh
V = 15 x 2 x 30
V = 900 cu.ft
V = 900 cu.ft x 7.48 gal/ cu.ft
V= 6,732 gal
Find the missing probability.
P(A) = ?
P(B) = 2/5
P(A and B) = 6/25
The missing probability will be P(A) = 3/25. The correct option is C.
What is probability?Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that an event is impossible, and 1 indicates that an event is certain. Probability is used in mathematics, statistics, and many other fields to quantify uncertain or random events.
To find the missing probability P(A), we can use the formula for the probability of the intersection of two events:
P(A and B) = P(A) * P(B|A)
Where P(B|A) is the conditional probability of B given A.
Rearranging this formula, we get:
P(A) = P(A and B) / P(B|A)
To find P(B|A), we can use the formula for conditional probability:
P(B|A) = P(A and B) / P(A)
Substituting this into the first formula, we get:
P(A) = P(A and B) / (P(A and B) / P(A))
Simplifying, we get:
P(A) = P(A and B) / P(B)
Substituting the given values, we get:
P(A) = (6/25) / (2/5)
Simplifying, we get:
P(A) = (6/25) x (5/2)
P(A) = 3/25
Therefore, the missing probability is P(A) = 3/25.

A study was conducted to investigate the effectiveness of a new aspirin-derivative in reducing pain. Results for randomly selected subjects are presented in the Assignment # 8 Excel worksheet. A lower score indicates less pain. The "before" value is matched to an "after" value and the differences are calculated ( on your excel worksheet ) . The differences have a normal distribution. Are the pain-reduction measurements, on average, lower after taking the new aspirin-derivative ? Test at a 1 % significance level.

Find the area of the shape using the formula for the area of a trapezoid:
A = 1/2(b1 + b2) · h
Where:
b1 = base 1
b2 = base 2
h = height
A = area
Plug in the given bases and height:
A = 1/2(7.5 + 2.5) · 2.5
Simplify:
A = 1/2(10) · 2.5
A = 5 · 2.5
A = 12.5 units²

SOLVE FOR X!!
(will mark brainliest))
Answer:
x=15
Step-by-step explanation:
Hello there!
The shown angles are vertical angles
if you didn't know vertical angles are congruent
That being said we can create equation
5x + 40 = 115
now we solve for x
step 1 subtract 40 from each side
40 - 40 cancels out
115 - 45 = 75
now we have 75 = 5x
step 2 divide each side by 5
5x/5=x
75/5=15
we're left with x = 15

A lottery offers one $900 prize, one $600 Prize, three $400 prizes, and four $100 prizes. One thousand tickets are sold at $5 each. Find the expectation if a person buys four tickets. Assume that the player's ticket is replaced after each draw and that the same ticket can win more than one prize. Round to two decimal places for currency problems.
Answer:
Expected value for 4 tickets = $ -7.6
Step-by-step explanation:
Given - A lottery offers one $900 prize, one $600 Prize, three $400 prizes, and four $100 prizes. One thousand tickets are sold at $5 each.
To find - Find the expectation if a person buys four tickets. Assume that the player's ticket is replaced after each draw and that the same ticket can win more than one prize. Round to two decimal places for currency problems.
Proof -
Given that,
A lottery offers
one $ 900 prize
one $ 600 prize
three $ 400 prizes
Four $ 100 prizes
And
One thousand tickets are sold at $ 5 each
Now,
If the person bought 1000 tickets then the prize he gets is
= 900 + 600 + 3×400 + 4×100
= 900 + 600 + 1200 + 400
= $3100
And
The cost of 1000 tickets = 5×1000 = $ 5000
Now,
Price 1 ticket = [tex]\frac{3100}{1000}[/tex] = $ 3.1
⇒Expectation of 1 ticket = $ 3.1 - 5 = $ -1.9 (Here $5 is price of 1 ticket)
⇒Expected value for 4 tickets = $ 4× -1.9 = $ -7.6
⇒Expected value for 4 tickets = $ -7.6
