Answer:
40%
Step-by-step explanation:
using the box method,
multiply 9 × 100
= 900 and divide 900 by 15
900 ÷ 15 = 60%
60% is the amount of pitches he hit
100% - 60% = 40%
he missed 40%
Answer:
5%
Step-by-step explanation:
For the Christmas dance, they will need 51 songs.
A number that is calculated by adding quantities together and then dividing the total by the number of quantities.
Given that, For the Christmas dance, the dance committee needs three hours of music. Each song is an average of 3.5 minutes.
Converting 3 hours into minutes,
1 hour = 60 minutes
3 hours = 60x3 = 180 minutes
Since, on song is of 3.5 minutes,
So, number of songs that will be played in 3 hours,
= 180/3.5
= 51.42
≈ 51
Hence, the party will have to play 51 songs.

A thrift is a kind of bank that arranges mortgages (mostly for home ownership) and sets up accounts to receive deposits.
The statement is actually false. The difference is in who they can borrow from and whether or not they are set up for profit. Thrifts are usually non profit.
of the dinner equally. However, since Matthew's dad provided concert tickets for the
group, the friends agree that Matthew doesn't have to help pay for the car service.
The friends divide this cost equally among themselves. If each friend spends a total of
$30, how many friends went to the concert with Matthew?

Answer: Hello there!
As we know, each 1/2 mile there is a red ribbon, each 1/8 mile there is a green ribbon, and each 1/4 mile there is a blue ribbon.
We want to know which color of ribbons is in the 3/4 mile marker.
then we need to see if 3/4 is a multiple of some of the previous numbers.
Start with the red ribbons, we need to see the quotient between 3/4 and 1/2, if the result is a whole number, then 3/4 is a multiple of 1/2
this is q = (3/4)/(1/2) = (3/4)*2 = 6/4
here we haven't a whole number, then there is no red ribbon at the 3/4 mile marker.
now with the green ones:
(3/4)/(1/8) = (3/4)*8 = 24/4 = 6
there we have a whole number, this means that at the 3/4 mile marker, we will see the sixth green ribbon, then we have a green ribbon in this marker.
now with the blue:
(3/4)/(1/4) = (3/4)*4 = 3
At the 3/4 mile marker, we will see the third blue ribbon, then there is a blue ribbon in this marker.
Then we know that in the 3/4 mile marker, there are a green and a blue ribbon.
7 girls. What is the
probability of randomly
selecting a boy?
binomial(16 + 7, 16) 2^(-(16 + 7)) = ((16 + 7)!)/(16! 7! 2^(16 + 7)) = 245157/8388608 ≈ 0.02922 ≈ 1/34.22
(assuming children are independent and male and female are equally likely)
| probability
less than 16 boys | 0.9534
16 or less boys | 0.9827
more than 16 boys | 0.01734
16 or more boys | 0.04657
fraction of boys | 16/(16 + 7) ≈ 0.695652
fraction of girls | 7/(16 + 7) ≈ 0.304348
expected value | 11.5
standard deviation | 2.398
variance | 5.75
