Use the rule of divisibility :
60 is composite because it is even so it can be divided by 2
67 is prime because none if the divisiblility rules work on it
65 is composite because it has a 5 by the end which means it can be divided by 5
<span>63 is composite because the sum of the digits equal to 9 which can be divided by 3 and 9</span>
They could be 28 + 29 + 30
1 pound = 16 ounces
2 pounds x 16 ounces = 32 ounces for the peaches.
32 ounces - 14 ounces = 18
The peaches weigh 18 more ounces.
Okay so i would do this with a logarithm.
5^(2x) = 28
take the log of both sides
log5^(2x) = log28 and because of this log rule: logA^n = nlogA
(2x)log5= log28
then divide by log5 on both sides
2x = log28 / log5
and divide by 2
x = (log28 / log5) /2
this can be found with a calculator:
x= about 1.03521...
round that to whatever the question says to
To solve this problem you must apply the proccedure shown below:
1. You have that the <span>data set has SSR=400 and SSE=100
2. Therefore you have </span><span>the coefficient of determination is:
r</span>²=SSR/SSTO
SSTO=SSR+SSE
3. Then, when you substitute the values, you obtain:
SSTO=400+100
SSTO=500
r²=400/500
4. So, you have that the result is:
r²=0.8
Therefore, as you can see, the answer for the exercise shown above is: <span> the coefficient of determination is 0.8</span>
