The amount of gasoline sold each month to customers at Bob's Exxon station in downtown Navasota is a random variable. This random variable can be described as having a normal distribution with mean 2500 gallons and a standard deviation of 200 gallons (and there is no seasonal variation in sales). Exxon will give Bob an all-expense paid trip to College Station, including a free dinner at Burger King, if his station pumps more than 2800 gallons in any one month.
What is the probability that Bob will win that wonderful trip on the basis of his gasoline sales this month?
Answer:
The probability that Bob will win that wonderful trip on the basis of his gasoline sales this month
P(X≥ 2800) = P(Z₁≥1.5) = 0.0768
Step-by-step explanation:
Step(i):-
Mean of the Population (μ) = 2500 gallons
Standard deviation of the population (σ) =200 gallons
Let 'X' be a random variable in Normal distribution
Given X = 2800
[tex]Z = \frac{x-mean}{S.D} = \frac{2800-2500}{200} = 1.5[/tex]
Step(ii):-
The probability that Bob will win that wonderful trip on the basis of his gasoline sales this month
P(X≥ 2800) = P(Z₁≥1.5)
= 0.5 - A(Z₁)
= 0.5 - A(1.5)
= 0.5 -0.4232 ( from normal table)
= 0.0768
Conclusion:-
The probability that Bob will win that wonderful trip on the basis of his gasoline sales this month
P(X≥ 2800) = P(Z₁≥1.5) = 0.0768

Jack dances clockwise around the Maypole, making one revolution every five seconds.
Starting from a point diametrically opposite Jack's starting point, Jill dances anticlockwise, making one revolution every six seconds.
How many times do they pass each other in the first minute?
Answer:
12 times. one min is 60 seconds. Jill went around 10 times. Jack 12 times. However Jack still passed Jill during his 12 revolutions. Her number is insignificant after you know who made more revolutions per min
The scale factor for the reduction is . The length of A = 20 (one-fifth) = 4 feet What is the length of B? B = feet
Answer:
1/5 5
Step-by-step explanation:
Answer: The scale factor for the reduction is 1/5. B= 5 feet
Step-by-step explanation:
The scale factor for the reduction is 1/5.
The length of A=20 (1/5)= 4 feet
What is the length of B?
B= 5 feet
Erik is building a cubby bookshelf, that is, a book shelf divided into storage holes (cubbies) instead of shelves. He wants the height of the bookshelf to be x2−4x−45
and the width to be x2+7x+10. Each cubby hole in the bookshelf will have a height of x+2 and width of x−9
.
Answer:
Step-by-step explanation:
Factor your equations using the fact that x²-Sx+P represents the general equation where S is the sum of roots and P the product of roots.
What roots will have the sum S=4 and product P= -45 ,
will have 5 and -9, S=5-9=-4✅ and P=5*(-9)=-45✅
x²-4x-45 = (x-root1) (x-root2) = (x+5)(x-9)
S=-7 and P=10 , so the roots are -5 and -2
x²+7x+10= (x+5)(x+2)
I am not sure what is your question yet you frobably need to factor the 2 given equation so you will have a bookshelf of (x+5)(x-9) by (x+5)(x+2)

There are 36 squares on each red and white checkered tablecloth. How many squares are there on 7,011 tablecloths? huryyyyyyyyyyyyyyyyyyy plz :(
Multiplying means adding a value a given number of times to zero
The number of squares in 7,011 tablecloths is 252,396 squares
The above number of squares in 7,011 tablecloths is correct for the following reason:
The known number of squares on each red and white checkered tablecloth = 36 squares
Required:
The number of squares in 7,011 tablecloths
Solution;
To find the number of squares on the 7,011 tablecloths, we have;
Number of squares in a given number of units of tablecloth = Number of squares per unit of tablecloth × Number of tablecloths
∴ Number of squares in 7,011 tablecloths = 36 squares × 7,011 tablecloth
Number of squares in 7,011 tablecloths = 36 squares × 7,011 tablecloth = 252,396 squares
The number of squares in 7,011 tablecloths = 252,396 squares

A pile of string measures to be 4 5/6 feet long. For a project Ms. Thompson wants to cut the long piece of string into several smaller pieces. Each piece that she cuts will measure 2/3 feet. How many whole pieces can she cut from the original piece of string if each piece is 2/3 feet long?
Answer:
7 pieces
Step-by-step explanation:
change 4 5/6 into an irregular fraction. 29/6
divide 29/6 by 2/3. to do this, flip and multiply
29/6 * 3/2 = 87/12 = 7.25 or 7 whole pieces
Please explain how to find the angle
We are given:
A right angled triangle with Perpendicular = 16 and base = 11
∠A = θ
Finding θ:
Using basic trigonometry, we know that Tanθ = Opposite / Adjacent
replacing the values for the angle θ
Tanθ = 11 / 16
[since 11 is the opposite side and 16 is the adjacent side to the angle]
θ = ArcTan(11/16)
θ = 34.5° OR 0.6 radians
Explain the process to solve the equation. Use proper vocabulary in your explanation. One-fourth x = negative five-eighths
Answer:
-2.5
Step-by-step explanation:
Your want to isolate the x. This is a multiplication problem, so use the inverse operation, which is division. Divide both sides of the equation by
1/4 by multiplying by the reciprocal, 4. (− 5
8)(4) is − 5/2. Use substitution to check the answer. x = − 5/2 :)
Answer: First, you isolate x by dividing 1/4 on both sides.
1/4x divided by 1/4 equals zero, which just leaves x, and -5/8 divided by 1/4 equals -5/2, so x = -5/2. -5/2 can be simplified to -2.5,
To check the answer, substitute x for -5/2:
* 1/4 multiplied by -5/2 equals -5/8
* 5/8 = 5/8, so this proves that my answer is correct.

Step-by-step explanation:
Second, first, fourth, third
Answer:
from least to greatest:
sea grass, red algae, green seaweed, mangrove.
mangrove is the shallowest depth
sea grass is the deepest
if the question is asking which is the deepest, then the answer is sea grass.
if the question is asking which number has the greatest value, the answer is mangrove.
if the question is asking which number has the greatest absolute value, then the answer is sea grass.
my guess is to start with mangrove. so put the values in as mangrove, green seaweed, red algae, sea grass.
if this is not correct, which it should be, put in these values as the opposite order. This is based on how you interpret the question.
