2 consecutive numbers....x and x + 1
x + x + 1 = 73
2x + 1 = 73
2x = 73 - 1
2x = 72
x = 72/2
x = 36
x + 1 = 36 + 1 = 37
so ur numbers are 36 and 37 <==
Answer:
The right answer is:
"The one-day SAT prep class produces statistically significant improvements in SAT writing performance."
Step-by-step explanation:
The P-value gives us the probability of getting the sample results, given that the null hypopthesis is true. That is why, it the P-value is small enough (smaller than the level of significance) is an indicator that the null hypothesis may not be true.
In this case, the P-value (0.028) is smaller than the level of significance (0.05), so the null hypothesis is rejected and we can conclude that there is significant difference for the studentes that take the SAT prep-class.
The population only include the students that take teh SAT prep-class, so it is not useful to compare to the performance of students that didn't take the class.
The right answer is:
"The one-day SAT prep class produces statistically significant improvements in SAT writing performance."
Okay, all of these pairs add up to 1 or 100%, except for one pair. I'll convert them all to decimals, so all must add up to 1.
3/8 = 0.375
0.625 + 0.375 = 1
62% = 0.62
0.38 + 0.62 = 1
7/8 = 0.875
0.875 + 0.125 = 1
70% = 0.70
1/3 <span>≈</span> 0.33
0.70 + 0.33 = 1.03
So the last pair of probabilities(70%, 1/3) does not belong with the other three because it does not add up to 1 like the others.
Answer:
It's not a function because the graph is not a straight line. Functions go in a line consistently such as up 2 and over 1.
