3/4 is greater than 1/4! Imagine a cake with four slices in it, would you rather eat one slice out of four or three slices out of four? Three slices out of four is more than just one slice, and the more the cake the better~ Hope this helps! c:
Using the Pythagorean theorem:
AC = √(13^2 - 12^2)
AC = √(169 -144)
AC = √25
AC = 5 cm
Answer:
Kim is 20 years old
Step-by-step explanation:
We have to make equations;
Kim= laura+10 so L+10
Laura is twice as old as Melissa so Laura will be
2 X M = 2M
<h2>Melissa is 5 years old now </h2>
Input values in to the equation
<h2>2M = 2X5= 10 years old (Laura)</h2>
As Kim is 10 years older than Laura it will be 10+10
<h3>which will give the answer of
20 </h3>
Multiply the 6 by 2x and 11 then you would add 15. You should then have on one side getting rid of the parenthesis 12x-51=3x+12. Add 51 and subtract 3x and you should get 9x=63. Then you would divide by 9 and get an answer of 7. To check you would plug 7 into the equation. 6(7•2-11)+15= 33 and 3•7 +12= 33
Answer:
Approximately normal for large sample sizes
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
The distribution is unknown, so the sampling distribution will only be approximately normal when n is at least 30.
So the correct answer should be:
Approximately normal for large sample sizes
