Answer:
Step-by-step explanation:
1x = number of chocolate chip cookies
3x = number of walnut cookies
5x = number of ginger cookies
5x = 40
x = 8
Total cookies = 1x+3x+5x = 72
Answer:
Step-by-step explanation:
Given that you drew all possible random samples of size 1,000 from the population of LSAT test takers
Plotted the values of the mean from each sample
As per central limit theorem, we find that for sample sizes of minimum 30, the means of all such samples randomly drawn would follow a bell shaped curve with normal distribution irrespective of the original distribution of the population.
Hence here answer is yes, this would be a normal distribution as per central limit theorem.
If the TV is 70% off, then that means she paid 30% of the original cost. If 30% of the original cost is $120, then...
30% * x = 120
.30x = 120
x = 120/.30
x = 400
The original cost was $400
Answer:
Value of x: 72, first option
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees. In order to find x, one of the angles, add the other two angle measures subtracted from the sum of angles (180) as such:
180 - (51 + 57) =
180 - 108 =
x - 72 degrees
