Answer:
25p^12q^6πcm²
Step-by-step explanation:
Given the area of the circle expressed as;
A = πr^2
Given
r = 5p^6q^3 cm
Substitute into the formula
A = π(5p^6q^3 )²
A = π(25p^12q^6)
A = 25p^12q^6πcm²
hence the area of this circle in square centimeters is 25p^12q^6πcm²
The area of the circle whose radius be 5p⁶q³ is 25πp¹²q⁶ square centimeters.
What is a circle?It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A circle has a radius of [tex]\rm 5 \ p^6 \ q^3[/tex] cm.
The area of the circle can be found using the formula
[tex]\rm A = \pi \ r^2[/tex]
Then the area of the circle will be
[tex]\rm A = \pi (5 \ p^6 \ q^3)^2\\\\A = \pi * 5^2 \ (P^6)^2 (q^3)^2\\\\A = 25 \ \pi \ p^{12} \ q^6[/tex]
Thus, the area of the circle is 25πp¹²q⁶ square cm.

A.mean because there is an outlier
B.median because there is an outlier
C.mean or median because there is no outlier
D.mode because there is an outlier
Answer:
it is B the median hope this helps :)
Step-by-step explanation:
Answer:
A. Mean
Step-by-step explanation:
When there is an outlier, the mean is the best way to figure out the average. Median doesn't work because it determines the exact middle, and the outlier (that 2) would affect it greatly, and the mode doesnt work, because it is the value that apears most in the data set, but just because it appears most doesnt mean its the average. In this case the mode is 102, but that is not the average. I hope this helps :)

At work, Mr. Grinnell receives 20 phone calls every 60 minutes. How many calls should he expect to receive in 180 minutes?
60
80
100
40
Answer:
Use a ratio.
20/60 = x/180
180/60 = 3, so 20*3 is 60.
The answer is 60.
Answer:
60
Step-by-step explanation:
Find out how many phone calls Mr. Grinnell receives in 1 minute.
60 mins = 20
1 min = 20 ÷ 60 = 0.333
180 mins = 0.333 x 180 = 59.94
59.94 rounded to the nearest whole number = 60
Jack correctly wrote another expression, 100−2t 100 - 2 t , to find the number of tickets Kate has now. Use the drop-down menus to explain what each part of Kate's and Jack's expressions mean.
Complete question :
Kate had 50 tickets to use for rides at the fair. She lost some of them. Her dad doubled the tickets she had left. Kate wrote the expression 2(50−t) to find the number of tickets she has now, where t t is the number of tickets she lost. Jack correctly wrote another expression, 100−2t, to find the number of tickets Kate has now. Use the drop-down menus to explain what each part of Kate's and Jack's expressions mean.
Answer:
50 means Kate's initial number of tickets
t = number of tickets she lost
2 = multiple by which her dad gave ; two times the number of her remaining tickets.
100 = double the number of initial tickets
2t = two times the number of tickets lost
Step-by-step explanation:
Kate's expression :
2(50 - t)
50 means Kate's initial number of tickets
t = number of tickets she lost
2 = multiple by which her dad gave ; two times the number of her remaining tickets.
Jack's expression:
100 - 2t
Jack's expression is an expanded for of Kate's equation
100 = double the number of initial tickets
2t = two times the number of tickets lost
2(50 - t) :
(2 * 50) - (2 * t)
100 - 2t

what is the positive solution to this equation?
4x²+12x=135
Answer:
x = 4.5
Step-by-step explanation:
Solve for x by using the quadratic formula
x = -12 + or - [tex]\sqrt{144+2160}[/tex] / 8
so (-12 + 48) / 8 or (-12 - 48) / 8
so 36/8 or -60/8, they just want the positive solution so x = 4.5

1. The function f(x) = -0.05(x2 - 26x - 120) represents the path coming out of the cannon. If x is the horizontal distance from the cannon, what does f(x) represent? (1 point)
Answer:
f(x) represents the vertical height of the cannon
Step-by-step explanation:
The given function is presented as follows;
f(x) = -0.05·(x² - 26·x - 120)
Given that 'x' represent the horizontal path of the cannon and the function describes the path of the cannon, we have that the vertical height reached by the cannon as it moves along the horizontal path is given as the function f(x)
Therefore, we have;
f(0) = -0.05·(0² - 26×0 - 120) = -0.05 × -120 = 6
f(0) = 6
The starting height of the cannon = 6
The maximum height reached by the cannon is given as follows;
f'(x) = d(-0.05·(x² - 26·x - 120))/dx = -0.05·d(x² - 26·x - 120)/dx = -0.05×(2·x - 26)
f'(x) = -0.05×(2·x - 26)
f'(x) = 0 At maximum height, therefore, we have;
-0.05×(2·x - 26) = 0
(2·x - 26) = 0
2·x = 26
x = 26/2 = 13
x = 13
f(13) = -0.05·(13² - 26×13 - 120) = 14.45
The maximum height = 14.45
Therefore;
f(x) = The vertical height of the cannon
Johnny and his father go fishing at 5:00 AM. After motoring 6 km upstream, Johnny writes a letter to his friend, puts the letter in a bottle, and drops it into the river. The bottle floats in the current and reaches at 7:40 AM the point where Johnny and his father began their trip. If the speed of the boat in still water is 9 km/h, what is the speed of the river current?
Answer:9/2 km per hour
Step-by-step explanation:
equation,
6/9-x + 6/x=8/3
Upstream is flowing of the boat in the opposite direction of the stream. The speed of the river current is 4.5 km per hour.
Given-Johnny and his father go fishing at 5:00 AM.
Total traveled by the Johnny and his father in upstream is 6 km.
The speed of the boat is 9 km/h.
What is upstream?
Upstream is flowing of the boat in the opposite direction of the stream.
Let x be the speed of the river current.
Time taken by the Johnny and his father to travel 6 km in upstream is ,
[tex]=\dfrac{6}{9-x}[/tex]
The time taken by the bottle to floats in the current river is,
[tex]=\dfrac{6}{x}[/tex]
As Johnny and his father start from 5:00 AM and the bottle reached to the point where Johnny and his father began their trip at 7:40 AM. Thus the total time is,
[tex]=7:40-5:00[/tex]
[tex]=2:40[/tex]
In hours,
[tex]=2\dfrac{40}{60}[/tex]
[tex]=\dfrac{8}{3}[/tex]
As the total time is equal to the sum of the Time taken by the Johnny and his father to travel 6 km in upstream and The time taken by the bottle to floats in the current river. Thus,
[tex]\dfrac{6}{9-x}+\dfrac{6}{x}=\dfrac{8}{3}[/tex]
[tex]\dfrac{6x+54-6x}{9x-x^2}= \dfrac{8}{3}[/tex]
[tex]\dfrac{27}{9x-x^2}= \dfrac{4}{3}[/tex]
[tex]x^2-9x+\dfrac{81}{4}=0[/tex]
On solving the above quadratic equation we get the positive value of the x is 4.5.
Thus the speed of the river current is 4.5 km per hour.

In a certain country the heights of adult men are normally distributed with a mean of 69 inches and a standard deviation of 2.2 inches. The country's military requires that men have heights between 64.6 inches and 73.4 inches.
Complete Question
In a certain country the heights of adult men are normally distributed with a mean of 69 inches and a standard deviation of 2.2 inches. The country's military requires that men have heights between 64.6 inches and 73.4 inches.
What percentage of this country's men are eligible for the military based on height?
Answer:
95.45 %
Step-by-step explanation:
We solve using z score formula
z-score iis z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 69
σ is the population standard deviation = 2.2
For x= 64.6 inches
z = 64.6 - 69/2.2
z = -2
Probability value from Z-Table:
P(x = 64.6) = 0.02275
For x= 73.4 inches
z = 73.4 - 69/2.2
z = 2
Probability value from Z-Table:
P(x<73.4) = 0.97725
The probability of this country's men are eligible for the military based on height is calculated as:
p(x = 73.4) - p( x = 64.6)
0.97725 - 0.02275
= 0.9545
Converting to Percentage is
= 0.9545 × 100
= 95.45 %

in how many ways can a supermarket chain select 3 out of 12 possible sites for construction of a new supermarket?
Answer:
its 220
Step-by-step explanation:
There are 220 ways supermarket chains can select 3 out of 12 possible sites for the construction of a new supermarket.
What are permutation and combination?A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Supermarket chains select 3 out of 12 possible sites for the construction of a new supermarket.
As we know,
[tex]\rm C(n, r) =\dfrac{n!}{( r! (n - r)! )}[/tex]
n = 12
r = 3
[tex]\rm C(12, 3) =\dfrac{12!}{( 3! (12 - 3)! )}[/tex]
C(12, 3) = 220
Thus, there are 220 ways supermarket chains can select 3 out of 12 possible sites for the construction of a new supermarket.
