Tiya flipped a coin 40 times. the coin landed heads up 16 times and tails up 24 times. part

Probability? I'm guessing it is asking for a written response so I'll try my best.

If the coin landed heads up 16 times then the probability would be 16/40 which can be reduced to 2/5
If the coin landed tails up 24 times you would do the same so 24/40 and then you can reduce that to 3/5

Part a: The experimental probability of it being tails would be 3/5
Part b: The experimental probability of it being heads would be 2/5

hopefully, I understood the question correctly but I believe this is the right answer

Answer:

a) Experimental probability = 0.4

a) Theoretical probability = 0.5

Step-by-step explanation:

Probability is the ratio of number of favorable outcome to total number of out comes.

Part a:

The experimental probability of the coin landing heads up

Total number of outcomes = 40

Number of favorable outcome = 16

Experimental probability $=\frac{16}{40}=0.4$

Part b:

The theoretical probability of the coin landing heads up

A coin has two sides head and tail,so probability of landing heads up is 0.5.

The given quadrilateral ABCD is a parallelogram since the opposite sides are of same length AB and DC is 4 and AD and BC is 2.

Step-by-step explanation:

ABCD is a quadrilateral with their opposite sides are congruent (equal).

The both pairs of opposite sides are given as AB = 3 + x , DC = 4x , AD = y + 1 , BC = 2y.

AB and DC are opposite sides and have same measure of length.
AD and BC are opposite sides and have same measure of length.

To find the length of AB and DC :

AB = DC

3 + x = 4x

Keep x terms on one side and constant on other side.

3 = 4x - x

3 = 3x

x = 1

Substiute x=1 in AB and DC,

AB = 3+1 = 4

DC = 4(1) = 4

To find the length of AD and BC :

AD = BC

y + 1 = 2y

Keep y terms on one side and constant on other side.

2y-y = 1

y = 1

Substiute y=1 in AD and BC,

AD = 1+1 = 2

BC = 2(1) = 2

Therefore, the opposite sides are of same length AB and DC is 4 and AD and BC is 2. The given quadrilateral ABCD is a parallelogram.

Answer:

30.25 in decimal form

30 1/4 in fraction form

Step-by-step explanation:

12(3) − 3(1/3) / 4(3)− (5) = 30.25 or 30 1/4

The histogram shows the number of miles driven by a sample of automobiles in New York City. What is the maximum possible number

hjlf

Answer:

The maximum possible number of miles traveled by an automobile included in the histogram is 40,000 miles.

Step-by-step explanation:

A histogram is a bar graph reprinting the frequency of various categories.

In a histogram the y-axis represents the frequency and the x-axis represents the categories.

Consider the histogram provided for the number of miles driven by a sample of automobiles in New York City.

The y-axis represents the frequency and the x-axis represents the number of miles driven.

The category 10,000 miles has the highest frequency at 30.

And the maximum possible number of miles traveled by an automobile is 40,000 miles.

Thus, the maximum possible number of miles traveled by an automobile included in the histogram is 40,000 miles.
