Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
Speed(Km/hr)___No of players__Relative freq
10--13.9_________4______4/612 = 0.0065359
14-17.9_________ 7______7/612 = 0.0114379
18-21.9________20_____20/612 = 0.0326797
22-25.9_______ 83_____83/612 = 0.1356209
26-29.9_______319____319/612 =0.5212418
30-33.9______ 179_____179/612 = 0.2924836
The percentage of players that had a top speed between 22 and 25.9 km/h was : 0.1356209 × 100 = 13.56%
c. The percentage of players that had a top speed less than 13.9 km/h was: 0.0065359 × 100 = 0.65%

For all the problems in this assignment you must enter your answers as a fraction or a product of fractions. For example, if your answer is 4/52 * 3/51 or 1 - 13/52 * 12/51, leave it in that form using * to indicate multiplication and ^ to indicate raising a number to a certain power. (eg. (5/6)^3 means 5/6*5/6*5/6 or (5/6)3.) a. Draw 2 cards with replacement. What is the chance that the first is a heart and the second is a heart
Answer:
13/52 * 12/51
Step-by-step explanation:
Given the question :
Probability of drawing two hearts from a card deck when picked without replacement :
Number of cards in deck = 52
Number of hearts in card deck = 13
Probability = required outcome / Total possible outcomes
First pick (p1) :
P(picking a heart) = 13 / 52
Second pick ( without replacement) (p2):
P(picking a heart) = 12 / 51
Hence,
P(heart on first and Second pick) :
P1 × P2
= 13/52 * 12/51

Give the vertex form and factored form of f(x)=x^2-12x+35.
What specific information does
each form provide?
Answer:
f(x)=(x-5)(x-7)
(x-6)²-1²
Step-by-step explanation:
Given:
Equation:
f(x)=x²-12x+35
Find:
Factories
Vertex form
Computation:
Factories
f(x)=x²-12x+35
f(x)=x²-(5+7)x+35
f(x)=x²-5x-7x+35
f(x)=x(x-5)-7(x-5)
f(x)=(x-5)(x-7)
So,
x = 5 , x = 7
Vertex form
By middle term divide by 2
12/2 = 6
So,
x²-12x+6²+35-6²
(x-6)²-1²

solve using substituion -5x + y = -2 -3x + 6y = -12
Answer:
x = 0y = - 2Step-by-step explanation:
-5x + y = -2………… Equation 1
-3x + 6y = -12 ………… Equation 2
Using substitution
Make y the subject in equation 1 and substitute it into equation 2 and solve for x
That's
y = 5x - 2
We have
- 3x + 6( 5x - 2) = - 12
- 3x + 30x - 12 = - 12
27x = - 12 + 12
27x = 0
Divide both sides by 27
x = 0
Substitute x = 0 into y = 5x - 2
We have
y = 5(0) - 2
y = - 2
So the solutions are
x = 0 y = - 2Hope this helps you
Does anybody know this?
Answer:
23
Step-by-step explanation:
So you want to add 7x degrees and (x-4) degrees. And it will be 8x - 4 = 180 degrees because it's 180 degrees in a straight line. And you want to + the 180 by 4 because there is -4 on the other side. so it will be 8x = 184 and you just divide 184 by 8 and it will be 23 easy. if you want to my help again you can text me on instargram jason_lee093
He uses a scale of 0.5 centimeter to 1 inch to draw the flag. The length of the scale drawing is 2.5 centimeters, and its width is 4.75 centimeters.
The scale is
0.5 cm = 1 inch
Multiply both sides by 2 to get
1 cm = 2 inches
To convert from the scale drawing to the actual dimensions, we will multiply by 2.
The scale length is 2.5 cm, which converts to 5 inches after multiplying by 2.
The scale width is 4.75 cm which converts to 9.5 inches after multiplying by 2.
The 2.5 cm by 4.75 cm flag on paper corresponds to a 5 inch by 9.5 inch flag in real life.

Suppose that, in 2000, France produced 6.122 million pounds of wheat. The total world production that year totaled 176 million pounds of wheat. What percent of the world's total production of pounds of wheat is contributed by France? Round your answer to the nearest tenth. Use P/100=A/B
Answer: 3.5%
Step-by-step explanation:
given data:
france production in 2000 = 6.122million pounds of wheat.
world production = 176 million pounds of wheat.
Solution:
france contribution from the workd total production in year 2000.
= P/100 = A/B
= 6.122/176 * 100
= 3.5%
france percentage contribution to the world total in the year 2000 was 3.5% of the world total.

Albert and John are partners in a Bakery store. They needed $70,000 to start the business. They
invested in the ratio 3:7, respectively. How much did Albert invest in the business? How much did John invest in the business?
Answer:
Albert invested 21,000 and John invested 49,000 :)
Answer:
A: $21,000J: $49,000Step-by-step explanation:
The number of "ratio units" in their investment ratio is 3+7 = 10. Albert's investment was 3/10 of the total, so was $21,000. John invested the remaining amount, $49,000.
Albert invested $21,000; John invested $49,000.
6z=3(z+8) solve for z
Answer:
z = 8
Step-by-step explanation:
First, distribute:
6z = 3z + 24
Then, we subtract 3z on both sides:
3z = 24
Finally, we divide 3 on both sides:
z = 8
Hope this helps ^^
Answer:
8
Step-by-step explanation:
First distribute the 3 inside the parenthesis.
6z=3z+24
Subtract 3z to both sides
3z=24
Divide each side by 3
z=8
