Each of three friends flips a coin 70 times. The results for each friend are shown in the tables. Find the relative frequency for the event "heads" for each friend. If the friends combine their results to get 91 heads and 119 tails, what is the relative frequency for the event "heads"? Use pencil and paper. Suppose each friend flips a coin 700 times. Is there a value you would expect the relative frequency for the event "heads" to be close to?
Answer:
Well the answer is simple fliping a coin is a 50/50 always

Is a triangle with leg lengths of 9 in. and 9 in. and hypotenuse of length √175 in. a right triangle?
Answer:
No
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
81 + 81 = c^2
162 = c^2
√162 = c
If it was a right triangle, its hypotenuse would be √162 inches long.

1) A deck of cards has 6 yellow, 6 green, and 3 orange cards. You pick 3 cards from the deck. Each card is returned to the deck after each one is chosen. What is the probability that you choose 3 orange cards in a row?
2) Examine the contents of the marble bag. What is the probability of choosing a red marble, blue marble, and green marble in that order? Each pick is not replaced. THE FIRST IMAGE IS FOR THIS QUESTION.
3) Each of the spinners shown are spun once. What is the probability that the first spinner will land on either letter A or B and the second spinner will land on an even number? THE SECOND IMAGE IS FOR THIS QUESTION.
Answer:
1) 3%
Step-by-step explanation:
Answer:
1) 1/125
2) 1/15
3) 1/6
Step-by-step explanation:
Total Cards = 6 + 6 + 3 = 15
Orange cards: 3
1) Chance of first card orange:
3/15, there are 3 orange, 15 total
Chance of second card orange:
3/15, since it is returned, there is the same chance, and the third the same
3/15 * 3/15 * 3/15 = 1/5 * 1/5 * 1/5 = 1/125
2) There are 6 total, 2 green, 2 blue, and 2 red.
The chance of getting a red marble first is 2/6, or 1/3, 6 marbles, 2 red.
The chance of getting blue second is 2/5, since picks aren't replaced.
Chance of getting green third is 2/4, or 1/2, since picks aren't replaced
1/3 * 2/5 * 1/2 = 2/30, or 1/15
3) First spinner has 6 total, 2 are A or B, so 2/6 or 1/3.
Second spinner has 4 total, 2 evens, so 2/4 or 1/2
Now multiply 1/3 * 1/2 = 1/6
The rate at which Pete’s Bakery can make pies is shown in the graph.
Question 1
Part A
How many pies can Pete’s Bakery make in 7 hours?
please answer all the questions shown in the image below
Answer:
A-
first x=1 and y=5then x=2 and y=10then x=3 and y=15then x=4 and y=20YES they are proportional because the answer every time is 5x
B- The x coordinate is growing by one and the y coordinate is growing by 5
C- for 0 t-shirts the y coordinate would be 0 as well, and for 5 shirts it would be 25 (5*5)
Focus on Math-
no it would not because instead of the equation looking like 5x it would look like 5x+4
Enjoy!!
(I have two questions)
Question 1. Karen bought a doll 2 ft. 8. in tall for her little sister. She found a box that is 29 in. long. Will the doll fit in that box?
Question 2. Dan's dog likes to to out in the backyard, which is 85 ft. wide. The dog's chain is 17 ft. 6 in. long. If Dan attaches one end of the chain to a pole in the middle of the yard, will his dog be able to leave the yard?
Answer:
For #1 no the doll wont fit in the box because there is 12 inches in a foot 12+12+8=32 so no.#2 Yes because half of of 85 is 42.5 and 85-17.6=67.4 and that wont make it half way.

The polygons are similar. Find the value of y
Answer:
4.5
Step-by-step explanation:
8/6= 6/y
Cross multiply:
8(y) = 6(6)
8y = 36
Divide both sides by 8:
8y/8 = 36/8
y = 4.5
