the garden
Answers
Answer:
The area of a circle with circumference 15.7 is 19.62
Step-by-step explanation:
If this helped May I have brainliest Im trying to rank up.
Have a great day!
The area of the garden is 19.64 feet²
The garden has the shape of a circle.
The area of a circle = πr²
Where:
π= pi = 22/7
r = radius
In order to determine the area of the garden, the radius has to be determined first. The radius would be determined from the circumference of the circle.
Circumference of the circle = 2πr
15.7 = 2 x (22/7) x r
r = 15.7 ÷ ( 2 x 22/7)
r = 2.50 feet
Area of the garden = (22/7) x (2.5²) = 19.64 feet²

8/x = 5/9 solve for x
Answers
i gotchu, x = 14.4
8/x = 5/9 (solve for x)
first you'd cross multiply (property of multiplication)
(8)(9) = (5)x
72 = 5x
then you flip your equation (communitive property)
5x = 72
then you need to eliminate five so you'd divide by 5 (inverse operation)
5x/5 72/5
x = 72/5
so x would be 14.4 since 72/5 is 14.4
(or just 14 since if you rounded it your answer would be 14)
decrease of 65% is the same as multiplying by what
percent?
Answers
Answer:
35%
Step-by-step explanation:
A decrease of 65% would be the same as multiplying the value by 35%.
100% - 65% = 35%
Let's use an example.
You have $150 dollars in stock and it decreases by 65%
150 - (.65*150) =
150 - 97.5 = $52.50
Now let's just multiply $150 by .35 (which is 35%)
150 * .35 = $52.50
It's the same!

Number making claims = 135 Number making claims = 24
Required:
a. Use a level of significance α = 0.05. Test to determine whether the claim rates differ between single and married male policyholders. Explain your determination.
b. Provide a 95% confidence interval for the difference between the proportions for the two populations.
Answers
Answer:
Step-by-step explanation:
Given the following :
Single policy holders (n1) = 900
Number making claims (x1) = 135
Married Policy holders (n2) = 400
Number making claims (x2) = 24
α = 0.05
a. Use a level of significance α = 0.05. Test to determine whether the claim rates differ between single and married male policyholders. Explain your determination.
Null: p1 - p2 = 0
Alternative : p1 - p2 ≠ 0
p = (n1p1 + n2p2) / n1 + n2 ;
p1 = x1/n1 = 135 / 900 = 0.15
p2 = x2/n2 = 24 / 400 = 0.06
p = (900*0.15 + 400*0.06) / (900 + 400)
p = 0.1223076
Test statistic (z):
(p1 - p2) / √p(1-p)(1/n1 + 1/n2)
(0.15 - 0.06) / √0.12231(1-0.12231)(1/900 + 1/400)
= 4.5710979
Decision:
Reject Null if P < α
Obtaining p value from z score using calculator :
P value = 0.0001
0.0001 < 0.05
Hence,
Reject Null

A bag has 5 yellow marbles, 3 red marbles and 2 blue marbles. Quinn randomly picks a marble from the bag and returns it before another is picked. How many times would Quinn expect to pick a blue marble if he picks a marble 200 times?
Answers
Answer:
Quinn can expect to pick blue 40 times
Step-by-step explanation:
the probability of picking blue is stated as 2/10 which can be reduced to 1/5
multiply the number of times they pick a marble ( shown as 200) by the probability of picking a blue one ( 1/5)
200 x 1/5 = 200 / 5 = 40
Quinn can expect to pick blue 40 times
Answer:40 blue marbles
Step-by-step explanation:
First find the probability of a blue marble
P (blue) = number of blue marbles / total marbles
= 2 blue/ ( 5+3+2) total
= 2/10
=1/5
We can use this since we return the marble to the bag each time
We multiply this by 200 for the number of times it is picked
200 * 1/5 = 40
We should expect to pick 40 blue marbles

A chef needs 60 oz of hot pepper sauce.
Which container size represents the better buy?
What will be the total cost of those containers?
Answers
Answer:
30-oz is a better buy
Total cost: $40.80
Step-by-step explanation:
The container with a lesser price per oz will be the better buy.
Let's calculate how much each container will give us per oz:
2-oz container = $1.99/2 = $0.995 per oz
5-oz container = $3.95/5 = $0.79 per oz
12-oz container = $8.76/12 = $0.73 per oz
30-oz container = $20.40 = $0.68 per oz
The 30-oz container is cheaper and would be a better buy.
In total the chef would buy 60-oz of hot pepper sauce for = 60-oz*$0.68 = $40.80
