Answer: 625100
Step-by-step explanation:
To begin, we would start multiply both numbers one by one.
(6.3 x 10^6) - 4.9 x 10^4
6.3 x 10^6 = 6300000
4.9 x 10^4 = 49000
Now, subtract (6.3 x 10^6) and (4.9 x 10^4)
6300000. 49000
6300000 - 49000 = 6251000
Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H_0: p1 - p2=0
H_a: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575
See the attached photo for the calculations for this test
Since there were 6 slices, and he ate 1/3, 6*1/3= 2, so he ate 2 slices
Answer:
The answer is A
Step-by-step explanation:
Supplementary angles are angles which add up to 180°
∠1 and ∠3 add up to 180°, so they are supplementary.
