3 hundredths - 3/100
3 tenths - 3/10
3/10 is the same as 30/100
3/100 less than 30/100 is 30/100-3/100 = 27/100
Answer: 27/100
Answer:
nCr = n! / (r!)(n-r!).
Step-by-step explanation:
That would be nCr = n! / (r!)(n-r!).
A quick way of working these out is as follows:
Take 7C4:
this is 7*6*5*4/4*3*2*1 Cancelling out the 4 and 3*2:
= 7*5
= 35.
15C12 = 15C(15-12)
= 15C3
= 15*14*13 / 3*2*1
= 5*7*13
= 455.
42 degrees. Divide 105 by 5 and get 21 and then multiply it by 2.
Answer:


Step-by-step explanation:
Given that A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz
For testing this claim, in Statistics we perform a certain measures called hypothesis testing.
For this first step is to create null and alternate hypothesis.
Normally null hypothesis would have some statistic = something
Here we want to test the mean weight of perfume
Hence null hypothesis would be
H0: mu = 8.9 fl oz.
Alternate hypothesis would be opposite of this claim
i.e.
Ha: mu ≠8.9 fluid oz
Hence answer is


Discount=$ 4
Discount percent :21.06%
solution given:
Marked price: $18.99
selling price: $14.99
Now
discount : Marked price - selling price
:$18.99- $14.99
:$4
Now
discount percent:
=
%
=21.06%
