The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means
Analysis the results of the investigation:Since the researcher selected a sample of 80 batters from summer baseball leagues and batters assigned to one of the two groups. So this means that the researcher is interested to know whether the mean no of hits should be different for two groups and both groups are independent to each other.

Raju bought an old car for Rs.125000 and spent Rs.25000 on its repair . He sold the car for Rs.200000 . Find his gain or loss percent .
Answer: [tex]33.33\%[/tex]
Step-by-step explanation:
Given
Raju buy an old car for [tex]Rs\ 1,25,000[/tex]
He spent [tex]Rs\ 25000[/tex] on its repair
The selling price of the car [tex]Rs\ 2,00,000[/tex]
So, the cost price is
[tex]\Rightarrow C.P.=1,25,000+25,000=Rs\ 1,50,000[/tex]
Here, [tex]S.P.> C.P.\quad \text{i.e. gain}[/tex]
Gain percent is
[tex]\Rightarrow \text{Gain percent}=\dfrac{2,00,000-1,50,000}{1,50,000}\times 100=\dfrac{50,000}{1,50,000}\times 100\\\Rightarrow \text{Gain percent}=33.33\ \%[/tex]

Find AC please, help is very much appreciated.
Answer:
AC ≈ 67.9
Step-by-step explanation:
15² = 9 (3x + 1 + 9)
225 = 9 (3x + 10)
225 = 27x + 90
135 = 27x
x ≈ 19.29
AC = (3x + 1 + 9)
AC = 3 (19.2857...) + 1 + 9
AC = 57.857... + 1 + 9
AC = 57.857... + 10
AC ≈ 67.9

write the recurring decimal 0.25656565656 as a fraction in its simplest form
Answer:
127/495
Step-by-step explanation:
Turning repeating decimals into fractions is a little like surgery: you need to make sure to "cut out" just the right part to let you simplify. In this case, it'd be very nice if we could deal with that repeating 0...565656... part. Let's start by giving our decimal a name:
[tex]x=0.25656...[/tex]
We're gonna split this into two parts: a number we can operate on, and "knife" to make the incision. For both, we'd like the only part to the right of the decimal to be the repeating part. To make our "knife," we'll multiply both sides of the equation by 10:
[tex]10x=2.5656...[/tex]
To make the number we'll be cutting from, we can shift the decimal point by any multiple of two more to the right. I'll keep things simple and stick with 2. This corresponds to multiplying the "knife" equation by 100 on both sides:
[tex]1000x=256.5656...[/tex]
Surgery time! To cut out the repeating bit, we can now just subtract the "knife" equation from the one above:
[tex]1000x-10x=256.5656...-2.5656...\\990x=254[/tex]
And just like that, it's gone! All that's left to do now is divide both sides by 990 and simplify:
[tex]x=254/990=127/495[/tex]

Determine whether you can construct many, one, or no triangle(s) with each description.
THIS IS WORTH 24 FREAKING POINTS SO GIVE ME NO WRONG ANSWER NOW, read the question carefully and answer it correctly and carefully
Answer:
I am not the best at math but I know that u can't change the bottom half of the fraction so it would just be four and then multiply the five and the three which would be fifteen. The answer would be 15/4ths. So you want to color in 15 boxes. Hopefully I could be of some kind of help to you!
Answer:
color in 15 boxes
15/32
Step-by-step explanation:
first off, the points are split so I'm only getting 12, just so that you know.
so 1/8x1/4 is 1/32, so each box is 1/32.
5/8x3/4=15/32 (multiply the top of the first with the top of the second and the bottom of the first with the bottom of the second)
so color in 15 boxes and the answer to the multiplication is 15/32

Determine whether a triangle with the given vertices is a scalene, isosceles, or equilateral triangle. Check all that apply.
9514 1404 393
Answer:
(a) isosceles
(b), (c) scalene
Step-by-step explanation:
The lengths of the sides can be found from the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.
We find triangle (a) has two sides the same length, so it is isosceles.
The other two triangles have three different side lengths, so they are scalene.
_____
Additional comment
It is impossible to specify an equilateral triangle using rational coordinates.
A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of
the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. Complete
sentences
Answer:
Volume of the prop = 706.5 in³
Step-by-step explanation:
Volume of the prop given in the picture = Volume of hemisphere + Volume of the cone
Volume of the hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex]
where 'r' = radius of the hemisphere
For r = 5 in,
Volume of the hemisphere = [tex]\frac{2}{3}(3.14)(5)^{3}[/tex]
= 261.67 in³
Volume of a cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here r = radius of the circular base
h = height of the cone
For 'r' = 5 in and h 17 in.
Volume of the cone = [tex]\frac{1}{3}(3.14)(5)^2(17)[/tex]
= 444.83 in³
Volume of the prop = 261.67 + 444.83
= 706.5 in³

The American Quarter Horse is the most popular riding horse in the world. The average weight of an American Quarter Horse at birth is 85 pounds. They grow to a maximum weight of 1300 pounds. Write and solve an inequality to find how many pounds an American Quarter Horse may gain from birth to adulthood.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the average weight of an American Quarter Horse at birth is 85 pounds and that they grow to a maximum weight of 1300 pounds.
The inequality to calculate the amount of pounds that an American Quarter Horse may gain from birth to adulthood will be the difference between it's maximum weight and weight at birth. This will be:
= 1300 - 85.
= 1215 pounds
Find the value of X please answer as soon as anyone can!
Answer:
139
Step-by-step explanation:
180 = x + 64+45
therefore: x = 139
Answer:
x = 109
Steps:
the sum of triangle angles is 180, and since the x is an exterior angle then 180-(64+45) = 71 and since it is an exterior angle then 180-71 = 109.

How do you find the circumference of a circle? Please include an example if you’d like.
Answer:
Step-by-step explanation:
Plug the given value of the diameter into the formula and solve.[2]
Example problem: You have a circle tub with a diameter of 8 feet, and you want to build a white fence that creates a 6-foot wide space around the tub. To find the circumference of the fence that has to be created, you should first find the diameter of the tub and the fence which will be 8 feet + 6 feet + 6 feet, which will account for the entire diameter of the tub and fence. The diameter is 8 + 6 + 6, or 20 feet. Now plug it into the formula, plug π into your calculator for its numerical value, and solve for the circumference:
C = πd
C = π x 20
C = 62.8 feet

3(2)^(n-1)3(-2)^(n-1)2(3)^(n-1)not geometric2(-3)^(n-1)Step-by-step explanation:
For these, you can find the appropriate formula by looking at the ratio of the first two terms. That will be the number in parentheses in the explicit formula. If there is no match, it is not geometric.
6/3 = 2 . . . an = 3(2)^(n-1)-6/3 = -2 . . . an = 3(-2)^(n-1)6/2 = 3 . . . an = 2(3)^(n-1)5/2 = 2.5 . . . not geometric (arithmetic sequence: an = 2+3(n -1))-6/2 = -3 . . . an = 2(-3)^(n-1)Tom made fruit punch for a party. He mixed 2 gallons of orange juice, 4 quats of pinnapple juice, 3 pints of cranberry juice. How many quarts did he make in all?
Answer:
13.5
Step-by-step explanation:
Tom made fruit punch for a party
He used the following amount of fruits
2 gallons of orange juice
= if 1 gallon is 4 quart then 2 gallon is 4×2= 8 quarts
3 pints of cranberry juice
= if 1 pint is 0.5 quart then 3 pints is 0.5×3 = 1.5 quarts
The amount of quartz he made can be calculated as follows
= 1.5 + 8 + 4
= 13.5
Hence he made 13.5 quarts of fruit punch

Answer:
48 stuff animals 24 myster boxes
Step-by-step explanation:
this is because the stuff animals have a greater than half the amount of getting. So you would then to 74/3. this is because if we split the total into thirds, we know that the stuff animals will have more than half. which will equal to 2/3. so will divide 74/3 we will 24, but since the stuff animals is 2/3 more likely, add or multiple 24 by 2 or add 24 again. giving us 48. then the remaining amount left of 74 will be left for the mystery boxers.
giving use the ration of 48:24
