<span>There are 100 possible pairs of numbers.
Half of them start with an even number so only 50 have a first odd number.
Of those remaining 50, half of those have an odd second number.
Leaving 25 of the original 100 to have two odd numbers.
P= 25/100=1/4</span>
Answer:
Since p > alpha, we accept H0, there is no evidence to prove that p1 is greater than p2
Step-by-step explanation:
Set up hypotheses as
(Right tailed t test)
Alpha = 0.05
Sample I II Total
X 117 141 248
N 249 312 561
p 0.4700 0.4519 0.4420
p difference = 0.0181
Std dev =
=0.0427
z statistic = 0.424
p value = 0.33724
Since p > alpha, we accept H0, there is no evidence to prove that p1 is greater than p2
Answer:
It's B
Step-by-step explanation:
Slope intercept form is Y=mx +b
(b is sometimes there when slope intersects the y axis)
Answer:
4 x + 5 = 2 x + 2 x + 5
Step-by-step explanation:
If we simplify the following equation it will be 4 x + 5 = 4 x + 5. This equation has infinitely many solutions because every value for x we substitute in, it will be the same on both sides, for example
Substitute x = 7 into 4 x + 5 = 4 x + 5
4 × ( 7 ) + 5 = 4 × ( 7 ) + 5
28 + 5 = 28 + 5
33 = 33
Every x value that we substitute in will result in the equation having the same result on both sides
