Answer:
(D)0.9836
Step-by-step explanation:
There are 365 days in a year.
Since each person has a different birthday:
- We can choose a birthday for the first person 365 out of 365 days.
- We can choose a birthday for the second person 364 out of 365 days.
- We can choose a birthday for the third person 363 out of 365 days.
- We can choose a birthday for the fourth person 362 out of 365 days.
Therefore,
P(4 randomly selected people all have different birthdays)

8 minutes longer will be the correct answer!
Step-by-step explanation:
First, let's find out how many minutes Gabriella played:
3:32 - 2:49 = 2:92 - 2:49 = 0:43
Check:
2:49 + 0:43 = 2:92 = 3:32
It's correct so...
43 - 35 = 8
Hope this helped!
Answer:
The expressions are not equivalent because Ella did not know that you can’t use substitution to test for equivalence.
Step-by-step explanation:
<u>Equivalent algebraic expressions</u> are those expressions which on simplification give the same resulting expression.
Two algebraic expressions are said to be <u>equivalent</u> if their values obtained by substituting any values of the variables are same.
Two expressions 3f+2.6 and 2f+2.6 are not equivalent, because when f=1,

Method of substitution can only help her to decide the expresssions are not equivalent, but if she wants to prove the expressions are equivalent, she must prove it for all values of f.

This is true only when f=0.
Hence,
The expressions are not equivalent because Ella did not know that you can’t use substitution to test for equivalence.
If it’s $14.00 upfront and 3 dollars per hour, subtract 14 from 32, which is 18, and divide that by 3, which is 6. She rented the bike for 6 hours.
Mean of data = sum of values ÷ number of data
We have three values; 84, 87, and

Sum of values =

=

We want the value of

to give mean between 85 and 90 inclusive





Hence, the value of

is between 84 and 99 inclusive
