Answer:
-0.462
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, is the population mean(the null hypothesis), is s is the standard deviation of the sample.
In this problem:
So
So the correct answer is:
-0.462
bearing in mind that 1Kg ≈ 2.2lbs.
so, if a baby is say 2.2lbs, and then it doubles in weight, to 4.4lbs.
well, we know when the baby was 2.2lbs it was exactly 1Kg, but when it went up to 4.4lbs, is it 2Kgs? well, yes, 2Kgs = 2.2 + 2.2 or 2(2.2).
so, multiplying the lbs value by some factor, will retain the Kg:lbs ratio.
Answer:
slope is 2/3, the y-intercept is -4
Step-by-step explanation:
y=mx+b
m is always the slope. b is always the y-intercept. please give brainliest!!
2 +4 +3 = 9 total balls
if they pick a white one first there would be 8 balls left
there are 2 blue ones so probability would be 2/8 which reduces to 1/4
Volume = area of base * height = 12 1/6 * 2 3/4 = 73/6 * 11/4 = 803/24
= 33 11/24 cubic feet
