10. Jenna flips two pennies 105 times. How

Studentka2010 [4]

Answer:

Step-by-step explanation:

When you flip two coins, you can have 4 different outcomes:

All outcomes are equally likely, but notice that if you do not keep track of which coin is which, you will get 1/4 of the flips to be both heads, 1/4 of the flips to be both tails, and 1/2 of the flips to be one heads and one tails.

p(both heads) = 1/4

With 105 flips, the expected number of both heads is

105 * 1/4 = 26.25

Answer: 26

PLEASE ANSWER ASAP! IMPORTANT! MUST BE CORRECT! GIVING OUT POINTS!

mr Goodwill [35]

So an even number is represented as 2n where n= a whole number
an odd is 1 more than an even so 2n+1 is odd

so even+odd=2n+2n+1=4n+1=
we see 2 2n's in there which are even
(even)+(even)+1
we know that even+even=even try that withe any 2 even numbers
then +1 means it's odd so therefor it is always true

Taylor surveys students in one grade level who own at least one pet. She finds that 50% of the students surveyed own 2 pets, 3 s

Llana [10]

First, we need to work out the total number of students who were being surveyed.

We know that half of the students has two pets. The rest of the students make up the other half. So, we have 3 students + 2 students + 8 students = 13 students that make half of the sample population

That means total number of students being surveyed is 13+13=26 students

Then we work out the probability
P(One pet) = 8/26 = 4/13
P(Two pets) = 1/2
P(Three pets) = 3/26
P( Four pets) = 2/26 = 1/13

The probability distribution is shown in the table below. Let $x$ be the number of pets and $P(X=x)$ is the probability of owning the number of pets

This holiday weekend, Dave is going to Chicago to shop and see a baseball game. To avoid traffic, Dave decides to take the train

kondaur [170]

Answer:

k= 1 mile per minute

Step-by-step explanation:

There is a proportional relationship between the time (in minutes) Dave spends riding the train, x, and the distance he travels (in miles), y.

The table representing this information is given below:

$\left|\begin{array}{c|ccccc}$x (minutes) & 8 &10&13&14 \\$y (miles) & 8 &10&13&14 \end{array}\right|$

The equation of proportionality is given as: y=kx

When x=8, y=8

Substituting we have:

8=8k

Divide both sides by 8

k=1

Therefore, the constant of proportionality, k= 1 mile per minute
