A popular resort hotel has 300 rooms and is usually fully booked about 7% of the time a reservation is cancelled before the 6:00 pm deadline with no penalty. What is the probability that at least 285 rooms will be occipied? Use the binomial distribution to find the exact value and the normal approximation to the binomial and compare your answers.
Answer:
Binomial distribution = 0.1026
Normal approximation = 0.1066
Step-by-step explanation:
Given that :
p = 100% - 7% = 0.93
n = 300
1 - p = 0.07
Probability of atleast 285 rooms getting booked :
P(x = x) = nCx * p^x * (1-p)^(n-x)
To obtain P(x ≥ 285) ; we use a binomial probability calculator to save time :
P(x ≥ 285) = 0.1026
Using Normal approximation :
Mean (m) = np = 300 * 0.93 = 279
Standard deviation (s) = sqrt(np(1-p) = sqrt(285*0.07) = 4.419 = 4.42
Using :
Z = (x - m) / s
P(x ≥ 285) ; for normal approximation :P(x ≥ x) x = 285 - 0. 5 = 284.5
Z = (284.5 - 279) / 4.42
= 1.2443
P(Z ≥ 1.2443) = 0.1066 (Z probability calculator)

22 is 44% of what number? Will mark brainliest! <3
Answer:
44% of 50 is 22.
This is the case because 50 * 0.44 is 22.
Let me know if you have any other questions :)
Answer:
50
Step-by-step explanation:
44% = 44/100
44/100 × X = 22
X = 22 × 100/44
X = 100/2
X= 50
hence, 44% of 50 is 22
7 divided by 9=28 divided by y
Answer:
7/9=28/y
We move all terms to the left:
7/9-(28/y)=0
Domain of the equation: y)!=0
y!=0/1
y!=0
y∈R
We add all the numbers together, and all the variables
-(+28/y)+7/9=0
We get rid of parentheses
-28/y+7/9=0
We calculate fractions
The required answer is y = 36 is the value that makes the equation true.
Given that 7 divided by 9=28 divided by y
A proportion is an equation that relates two ratios or fractions, stating that they are equal. It can be used to solve problems involving ratios or to find an unknown value.
To solve a proportion, we use the concept of cross-multiplication. This involves multiplying the numerator of one fraction by the denominator of the other fraction and setting the two products equal to each other.
To find the value of y in the equation 7 divided by 9 = 28 divided by y, set up a proportion and solve for y.
The proportion can be written as:
7 / 9 = 28 / y
To solve for y, by cross-multiplication:
7 x y = 9 x 28
Simplifying:
7y = 252
Dividing both sides of the equation by 7:
y = 252 / 7
y = 36
Therefore, the value of y that satisfies the equation 7 divided by 9 = 28 divided by y is y = 36.
Substitute y = 36 into the equation, gives:
7 / 9 = 28 / 36
After simplifying both sides of the equation, we find that both fractions are equal to 4/9.
Hence, y = 36 is the value that makes the equation true.

Beth is putting up a fence in her yard so her dog can play outside. She purchased 80 feet of fencing. If the fenced area is a rectangle with a width of 30 feet, what is the length of the fenced area?
Answer:
10 feet
Step-by-step explanation:
The formula for the Perimeter fo a rectangle
= P = 2L + 2W
Where:
L = Length
W = Width
From the question
P = 80 feet
W = 30 feet
Hence:
80 = 2L + 2(30)
80 - 2(30) = 2L
80 - 60 = 2L
20 = 2L
L = 20/2
L = 10 feet
Hence, the length of the fenced area = 10 feet

Because of PEMDAS, Simplify 15x72 first. That will bring you to 1080. After that we add 6 to the 1080 because you always do Multiplication first. Your answer would be 1086 if you followed PEMDAS correctly.

Identify the graphed linear equation?
Answer:
C
Step-by-step explanation:
The first thing I notice is the slope, which is going down, which means this is for sure a negative slope. So any slopes that just include 5 is now crossed off. And since the formula goes like y=mx+b, I believe the answer would be C, because it actually follows the formula as it should. If I'm wrong, pick D for sure.

19) If you choose from the following M 8 M colors, what is the probability that you choose blue? 5 green 6 yellow 8 blue 7 brown
7/26
3/26
8/26
1/26
What’s the answer
Answer:
The answer is C, or the third one (8/26).
Step-by-step explanation:
You add up all the objects (5+6+8+7) and get a total of 26 objects. Now you go to the amount of blue ones, and it's 8. So your probability of getting a blue one is 8 out of 26, since there's 8 blue ones out of the total 26. You can write this as 8/26, which is the answer.
A clothing store is having a sale. Last week, a coat originally priced at $110 and was discounted by 45%. This week, the coat was discounted by 30% of last weeks sale price. What is the price of the coat after the second discount is applied
Answer:
The price of the coat after the second discount is applied is $42.35.
Step-by-step explanation:
First, you need to find the amount after the first discount by multiplying the original price by 45% and subtracting that amount from the initial price:
$110*45%=$49.5
$110-$49.5=$60.5
Now, you have to find the price of the coat after the second discount by calculating 30% of the price after the first discount and subtracting the result from that price:
$60.5*30%=$18.15
$60.5-$18.15=$42.35
According to this, the answer is that the price of the coat after the second discount is applied is $42.35.

Why do -8 and 8 have the same absolute values?
Answer:
Absolute value means the non-negative, or the positive, of it's number, since eight is already a positive number, it's absolute value remains positive eight.
But since -8 is a negative number, the absolue value will give eight it's non-negative, which is positive eight.

Complete Question
Mariah and Clarence are planning for a dinner party. The grocery store is selling a 25- pound turkey for $60 . Mariah states, "that means it costs $2.40 per pound of turkey." Clarence states, "that means $2.4 pounds of turkey cost $1 Is Mariah's statement, Clarence's statement, both statements, or neither statement correct?
Answer:
Mariah's statement is correct
Step-by-step explanation:
Mariah and Clarence are planning for a dinner party. The grocery store is selling a 25- pound turkey for $60 .
From the statements given above, we are to find the unit rate . This means the cost of the turkey per pound
Hence, the calculation is given below:
25 pounds of turkey = $60
1 pound of turkey = x
Cross Multiply
25 × x = $60 × 1
x = $60/25
x = $2.40
1 pound of turkey cost $2.40
Therefore, Mariah's statement is correct
