Answer:
16 shirts and 48 ties
Step-by-step explanation:
you start with 64 and divide it by 4 i got four cause it says that James had THREE times as many ties as shirts leaving him with leaving him with 3 groups of ties and 1 group of shirts . dividing 64 by 4 leaves you with 16 which is the amount of shirts he has and then you would multiply 16 by 3 to get the amount of ties he has.
Answer:
So the answer for this case would be n=107 rounded up to the nearest integer
Step-by-step explanation:
Information given
the sample mean
the sample deviation
the sample size
Solution to the problem
The margin of error is given by this formula:
(a)
And on this case we have that ME =0.001 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
We can use as estimator of the real population deviation the sample deviation for this case 
/ The critical value for 99% of confidence interval is given by 
, replacing into formula (b) we got:
So the answer for this case would be n=107 rounded up to the nearest integer
Answer:
-2
Step-by-step explanation:
First you should write out the entire word equation into one you may recongnize:
7x - 12 = -3x - 32
After this, solve for x:
7x + 3x = 12 - 32
<u>10x</u> = <u>-20</u>
10 10
x = -2
the number is -2

Solution:
Find 1/3 of 63.
63 / 3 = 21
21 students gave a speech today.
63 - 21 = 42
Find 2/3 of 42.
42 / 3 = 14
14 x 2 = 28
28 of the remaining students gave their speeches.
42 - 28 = 14
-----------------------------------------------
Answer:
14 students haven't given their speeches!
