Answer:
72 or 75
Step-by-step explanation:
If we are going in order then the median would be 72.
If we are going by what you posted, then it would be 75.
You were asking about the mean, so I though I would just add it in here.
So basically, the mean is just where you add up all the numbers, and then divide them by how many numbers you have.
For your problem, this is 39+87+72+88+75+87+15+53+53. This equals 569.
Now, lets count how many numbers we added: 1...2...3...4...5...6...7...8...9.
Ok, so lets divide the 569 by 9. This should get you 63.222...
That is your mean.

A number raised to a fraction would be the same as a root to the inverse of the fraction.
What that means is the sqrt(8) raised to 1/4 is the same as being 4th root of 8.
So rewriting the given equation you would have cubic root 8 x 4th root 8
Combine the roots by multiplying: 3 x 4 = 12
The equivalent equation would be C. 12 root 8 ^ x

- Each friend has 10 nails to paint
- There are 8 friends
- Jackie finished painting 4 friend's nails
If there are 8 friends, and each friend has 10 nails to paint, then there are 80 nails that need to be painted in total.
Jackie finished painting 40 nails.
So the math sentence will be:
80 - 40 = 40
--------------------------------------------------
Jackie needs to paint 40 more nails.

A.144/8.64=x
B.x/144=8.64
C.8.64-x=144
D.144x=8.64
Answer:
144x=8.64
This way you can divide by 144 to find how much each individual pencil costs
Consider a taxi station where taxis and customers arrive in accordance with Poisson processes with respective rates of one and three per minute. A taxi will wait no matter how many other taxis are present. However, an arriving customer that does not find a taxi waiting leaves. Find the proportion of arriving customers that get taxis.
Answer:
The proportion of arriving customers that get taxis is:
= 33%.
Step-by-step explanation:
Rate of arrival of taxis = 1 per minute
In one hour, the number of taxis arriving = 60 (60/1)
Rate of arrival of customers = 3 per minute
In one hour, the number of customers arriving = 180 (60 * 3)
The proportion of arriving customers that get taxis = 60/180
= 0.333
= 33%
b) Since the taxis wait until they get a customer, it means that they will likely transport one out of 3 customers who arrive. Therefore, the proportion of arriving customers that get taxis is equal to 1/3 or 60/180, which is equal to 33%.

You buy a new backpack that costs $62.00. The sales tax is 6.5%. What is the total amount you need to pay, including tax?
Answer:
$66.03 in total.
Step-by-step explanation:
$66.03 because 6.5% is 0.065 and $62.00 times 0.065 equals $4.03. $62.00 plus $4.03 is $66.03.
a bakery place the following price for bagels one bagel for $1.50 two bagels for$2.25 a half a dozen for
$6.50 a dozen for $12 is the price per bagel proportion 2 the number of bagels brought.
Answer:
no
Step-by-step explanation:
1 bagel $1.50 ---------> unit cost: $1.50/bagel
2 bagels $2.25
6 bagels $6.50
12 bagels $12 ---------> unit cost: $1/bagel
Since the unit costs are not equal, the prices are not proportional.

Hello your question is poorly written the complete question is attached below
answer :
a) H0 : p1 = p2
Ha : p1 ≠ p2
b) Z = -0.58
c) P-value = 0.561915
d) we will reject the Alternative hypothesis
Step-by-step explanation:
For sample 1 ; n1 = 254 , x1 = 28
For sample 2 ; n2 = 301 , x2 = 38
level of significance ∝ = 0.01
P1 = X1 / n1 = 28 / 254 = 0.1102
P2 = X2 / n2 = 38 / 301 = 0.126
a) Determine the null and alternate hypothesis
H0 : p1 = p2
Ha : p1 ≠ p2
b) Determine Test statistic
we perform a Z-statistic to test the hypothesis
Z = [tex]\frac{p1-p1 }{\sqrt{( p(1-p)*(\frac{1}{n1}+\frac{1}{n2}) ) } }[/tex] -------- ( 1 )
p = ( x1 + x2 ) / ( n1 + n2 )
= ( 28 + 38 ) / ( 254 + 301 ) = 0.1189
Where: p = 0.1189 , p1 = 0.1102 , p2 = 0.126 ( input values into equation 1 )
∴ Z = -0.58
c) Determine P-value
P-value = 0.561915 ( using excel function )
d) conclusion : since p-value > 0.01 ( level of significance ) we do not reject the null hypothesis. therefore it proves that p1 = p2

15 people working 5 hours per day can make 30 units of a product in 10 days. Assuming all other factors remaining
constant and people of same efficiency are used to make the same products, in how many days can 10 people
make 10 units of the product if each of them works 10 hours per day?
SELECT ONLY ONE
2.5 days
7.5 days
12 days
26 days
The required number of days is 2.5 days
First, we need to calculate the amount of units generated per day.
If 15 people working 5 hours per day can make 30 units of a product in 10 days, then the amount of units per day is calculated as:
Units per day = (15*5*10)/30
Units per day = 750/30
Units per day = 25 units/day
If people of the same efficiency are used to make the same products, the number of days needed by 10 people to make 10 units of the product if each of them works 10 hours per day will be;
Number of days = (25*10)/10*10
Number of days = 250/100
Number of days = 2.5 days
Hence the required number of days is 2.5 days

The length of a rectangle is 3 yards less than 5 times the width. If the perimeter is 102 yards, find the length and the width of the rectangle.
Answer:
Width = 9 yards, length = 42 yards
Step-by-step explanation:
Perimeter = 2xlength + 2xwidth. Let's call length L and width W. The question also states that L = 5W-3. Therefore, 102 = 2x (5W-3) + 2W. Then, 102 = 12W - 6. 108 = 12W, so W = 9 yards. Since L = 5W - 3, we get 45-3 = 42 yards.

Answer:
area: 524 cm²perimeter: 124.8 cmStep-by-step explanation:
The rectangle in the middle has a width equal to the radius of the semicircular ends, so (20 cm)/2 = 10 cm.
The semicircular ends, together, make a complete circle of radius 10 cm.
The area is the sum of the areas of the parts:
A = LW = (21 cm)(10 cm) = 210 cm² . . . . . . rectangle area
A = πr² = π(10 cm)² = 100π cm² ≈ 314 cm² . . . . . circle area
The total area is ...
210 cm² +314 cm² = 524 cm² . . . . area of the figure
__
The perimeter of the figure is the sum of the lengths of all of the edges. From the left, working clockwise, we have ...
P = (1/2 circle of diameter 20) + (rectangle top = 21) +(1/2 circle of diameter 20) +(circle radius = 10) +(rectangle bottom = 21) +(circle radius = 10)
The two 1/2 circles add to a whole circle with a circumference of ...
C = πd = (3.14)(20 cm) = 62.8 cm
Then the whole perimeter is ...
P = 62.8 cm + 21 cm + 10 cm + 21 cm + 10 cm = 124.8 cm

Note that we have used 3.14 for pi. If you use a more exact value, your answers will be slightly different.
