A hot dog vendor at Wrigley Field sells hot dogs for $1.50 each. He buys them for $1.20 each. All the hot dogs he fails to sell at Wrigley Field during the afternoon can be sold that evening at Comiskey Park for $1 each. The daily demand for hot dogs at Wrigley Field is normally distributed with a mean of 40 and a standard deviation of 10.a. If the vendor buys hot dogs once a day, how many should he buy?b. If he buys 52 hot dogs, what is the probability that he will meet all of the day’s demand for hot dogs at Wrigley?
Answers
Answer:
43 ; 0.88493
Step-by-step explanation:
Using the Zscore formula :
Zscore = (x - m) / s
m = mean ; s = standard deviation
Profit = $1.5 - $1.2 = $0.3
Loss = $1.2 - $1 = 0.2
Cummlative probability :
Profit / (profit + loss)
0.3 / (0.3 + 0.2) = 0.3 / 0.5 = 0.6
To obtain the x, at Z at 0.6 = 0.26
m = 40 ; s= 10
Hence,
0.26 = (x - 40) / 10
0.26 * 10 = x - 40
2.6 = x - 40
2.6 + 40 = x
x = 42.6 `; 43 approximately
Probability of meeting day's demand at Wrigley
x = 52
P(x < 52) :
Zscore = (52 - 40) / 10
P(Z < 1.2)
Z = 0.88493
Josh paid for four books with 3 20$ bills He received 16 $ in change Each book cost the same amount how much did each book cost
Answers
Answer:
each book cost $11
Explanation: If Josh paid for 3, 20 bills he would be paying $60, and if he got $16 in exchange you could subtract that from the amount he gave (60-16 = 44) then you would get how much all the books costs TOGETHER. But what you need to find is how much each book costs, you know they all cost the same and how much books he bought (4) so you just divide 44 by 4 which would get you 11.

The number from the equation is less than 11
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be = x
Now , the equation is
Sum of a number and 3 more than twice the number is less than 36
Let us assume the sum of the numbers is 36
So ,
x + 3 more than twice the number = 36
And ,
x + ( 3 + 2x ) = 36
On simplifying the equation , we get
3x + 3 = 36
Subtracting 3 on both sides , we get
3x = 33
Divide by 3 on both sides , we get
x = 11
But , the inequality equation is less than 36
So , x < 11
Therefore , the number is less than 11
Hence , the number from the equation is less than 11

Answers
Answer:
B
Step-by-step explanation:
If the 2 lines were parallel, then
5x - 10 = 70 ( alternate angles )
Add 10 to both sides
5x = 80 ( divide both sides by 5 )
x = 16
For the 2 lines to be parallel then x = 16
Answer:
B.16
Step-by-step explanation:
First I would Make an equation:
For example set (5x-10)=70
Add 10 to both sides:
5x-10+10=70+10
Simplify:
5x=80
Divide both sides by 5:
5x/5=80/5
simplify:
x=16
In conclusion the answer is B.16
