Answer:
75.4yd
Step-by-step explanation:
Find the diagram attached
Perimeter of the figure = perimeter of the 4 semicircles
Perimeter of a semicircle = πd/2
d is the diameter of the semicircle = 12yd
Perimeter of a semicircle = 3.14(12)/2
Perimeter of a semicircle = 37.68/2
Perimeter of a semicircle = 18.94yd
Perimeter of the 4 semicircles = 4 * 18.94
Perimeter of the 4 semicircles = 75.36yd
Hence the perimeter of the swimming pool to nearest tenth is 75.4yd

A can of tomato sauce has a volume of 903 cm3 and a height of 11.5 cm. What is the diameter of the can? Group of answer choices 7 cm 5 cm 2.5 cm 10 cm
Answer:
10 cm
Step-by-step explanation:
the can is shaped like a cylinder
first step is to find the radius and then multiply the figure by 2
volume of a cylinder = nr^2h
n = 22/7
r = radius
903 = 11.5 x r^2 x 3.14
r^2 = 903 / (3.14 x 11.5)
r = 5 cm
diameter = 10cm
Determine which statements are reasonable conclusions based on the data.
Choose Yes or No for each statement.
a. The point at (19, 14) is an outlier because it is outside the main cluster of data.
b. As the number of hits increases, the number of runs scored tends to decrease.
There is a positive linear association between the number of hits and the
number of runs scored.
d. There is a non-linear association between the number of hits and the
number of runs scored.
The point at (7, 13) is an outlier because it is the only game for which the
number of runs is greater than the number of hits.
f. If the trend continues, for a game when Tyler's team gets 20 hits, the number
of runs scored will most likely be greater than 10.

Suppose that among all U.S. Students, 80% have gone to an amusement park and 45% have gone to a beach. Only 15% have done neither. If you select a student at random, what is the probability that the student has gone to the beach but not to an amusement park
Answer:
5%
Step-by-step explanation:
Let x represent the percentage of people that have gone to both the park and the beach.
The percentage of people that have gone only to the amusement park = 80% - x% = 80 - x
The percentage of people that have gone only to the beach = 45% - x% = 45 - x
Therefore:
100% = (80 - x) + (45 - x) + (x) + (15)
100 = 80 + 45 + 15 -x - x + x
100 = 140 - x
x = 140 - 100
x = 40%
Therefore 40% of the students have gone to both the park and the beach.
The probability that the student has gone to the beach but not to an amusement park = 45% - 40% = 5%

Which answer represents the series in sigma notation? −7+(−2)+3+8+13 ∑j=15(5j−12) ∑j=15(−8j+1) ∑j=15−5(15)j−1 ∑j=155j−1
Answer:
∑j=15(5j−12)
Step-by-step explanation:
For j = 1 up to j = 5
j = 1
(5j - 12) = (5(1) - 12) = 5 - 12 = - 7
j = 2
(5j - 12) = (5(2) - 12) = 10 - 12 = - 2
j = 3
(5j - 12) = (5(3) - 12) = 15 - 12 = 3
j = 4
(5j - 12) = (5(4) - 12) = 20 - 12 = 8
j = 5
(5j - 12) = (5(5) - 12) = 25 - 12 = 13
(-7 + (-2) + 3 + 8 + 13)
Answer:
(5j-12)

What are the ordered pairs of the
solutions for this system of equations?
f(x)=x^2 – 2x + 3; f(x) = -2x + 19
(4, [?]); ([ ], [])
Answer:
(4, 11) is one ordered pair and (-4, 27) is the other ordered pair
Step-by-step explanation:
(1) f(x) = x^2 - 2x + 3 (2) f(x) = -2x + 19
-2x + 19 = x^2 - 2x + 3
x^2 - 16 = 0
(x - 4)(x + 4) = 0
x = 4 or x = -4 -2(4) + 19 = 11
-2(-4) + 19 = 27
So, when x = 4, y = 11 and when x = -4, y = 27
(4, 11) is one ordered pair and (-4, 27) is the other ordered pair

Answer:
8/5 oz
Step-by-step explanation:
The problem is saying that there are 8 ounces of cheese and 5 bowls of spaghetti you need to divide the cheese over. As you need an equal amount of cheese in each bowl, you have to divide 8 ounces by the number of bowls, which is 5. Thus, you would do 8 divided by 5, which we just say is 8/5. Therefore, your answer is 8/5 ounces of cheese (or simplified to 1 3/5).

using substitution
x+3y=3
3y-2x=12
Step-by-step explanation:
Given :-
x + 3y = 3 3y - 2x = 12And we need to solve the equation using Substituting method . So on taking the first equation ,
[tex]\rm\implies x + 3y = 3 \\\\\rm\implies x = 3 - 3y [/tex]
Put this value in (ii) :-
[tex]\rm\implies 3y - 2x = 12 \\\\\rm\implies 3y - 2(3-3y)=12\\\\\rm\implies 3y -6-6y = 12 \\\\\rm\implies -3y = 18 \\\\\rm\implies y = -6 [/tex]
Put this Value in (I) :-
[tex]\\\\\rm\implies x = 3-3*-6 \\\\\rm\implies x = 3+18 \\\\\rm\implies x = 21 [/tex]
Hence the Value of x is 21 and y is (-6) .
Answer:
x = -3
y = 2
Step-by-step explanation:
Ok this is a long one but bear with me lol, i promise i will make it easy to understand, performing one step at a time.
So we are given 2 equations right? We can take any of these one equation and isolate any one variable, either x or y, I will take the first equation and isolate x from it cuz it's the easiest way;
=> x + 3y = 3
=> x = -3y + 3 (Let's pretend this is not an equation for x but a "value")
Now that we have the x isolated from first equation, we can substitute x "value" in for the x in second equation. To solve for y;
=> 3y - 2 (-3y + 3) = 12
=> 3y + 6y - 6 = 12
=> 9y - 6 = 12
=> 9y = 12 + 6
=> 9y = 18
=> y = 18/9
=> y = 2
At this point we are almost done with the question! So since we got a real value for one of our variable (which in this case is y-value), we can substitute that in any of the given equation, We can also use the equation where in we isolated "x", so I'll use that cuz it's gonna require less steps, to find the real x-value:
=> The equation we found out up there is: x = -3y + 3
=> Now just simply substitute the y-value we figured in the equation above:
=> x = -3y + 3
=> x = -3(2) + 3
=> x = -6 + 3
=> x = -3
Ayee we did it lol so the final answer would be:
x = -3
y = 2
I really hope this made sense, and that it helps!

A 2.20 x 10-6 F capacitor is hooked
up to a 14.0 V power supply. How
much energy is stored in the
capacitor?
Answer:
[tex]E=2.15\times 10^{-4}\ J[/tex]
Step-by-step explanation:
Given that,
The capacitance of the capacitor, [tex]C=2.2\times 10^{-6}\ F[/tex]
Voltage of the power supply, V = 14 V
We need to find the energy stored in the capacitor.
The formula for the stored energy in the capacitor is given by :
[tex]E=\dfrac{1}{2}CV^2[/tex]
Put all the values,
[tex]E=\dfrac{1}{2}\times 2.2\times 10^{-6}\times 14^2\\\\E=2.15\times 10^{-4}\ J[/tex]
So, [tex]2.15\times 10^{-4}\ J[/tex] of energy is stored in the capacitor.

Find the x-intercept(s) and the coordinates of the vertex for the parabola y=x + 2x-15. If there is more than one x-intercept, separate them with commas,
Step-by-step explanation:
y = x^2 + 2x - 15
To find the x-intercepts, factor out the right side:
y = x^2 + 2x - 15
= (x + 5)(x - 3)
This means that the x-intercepts are at (-5, 0) and (3, 0).
Method 1:
The x-coordinate of the vertex of a parabola is given by the following:
x = -b/2a, where a = 1 and b = 2
= -(2/(2×1))
= -1
Using this value of x gives y = -16
Therefore, the coordinates of the vertex is (-1, -16).
Method 2:
We can find the x-coordinate of the vertex by taking the derivative of y and equating it to zero:
y' = 2x + 2 = 0 ---> x = -1
Using this value of x into our equation, we get y = -16.
Therefore,
vertex: (-1, -16)
Find the median of 85, 42, 64, 71, 39, 56, 26
Answer:
56
Step-by-step explanation:
1. first order the numbers from least to greatest (26, 39, 42, 56, 64, 71, 85)
2. Then count how many numbers you have and divide it by 2. We have 7 numbers, so we’ll divide by 2 and round up because 7 is an odd number. (7 divided by 2 =3.5, rounded up is 4.)
3. Now we know the position of the number is this 4th spot, so the median is 56.
The median of the given set of numbers is 56.
What is the median of data?
The median is defined as the value range. To get it, arrange the numbers in ascending order from smallest to largest, then hide one number on either end until you reach the center.
The given set of data as:
{85, 42, 64, 71, 39, 56, 26}
Let's arrange the given numbers in ascending order: 26, 39, 42, 56, 64, 71, 85.
Since we have 7 numbers, which is an odd count, the median is the middle number.
In this case, the middle number is the fourth number, which is 56.
Therefore, the median of the given set of numbers is 56.
