Answer:
(a+b)² - 2ab
Step-by-step explanation:
it is a formula :)
Answer:
a) There is no enough evidence of an increase in life expectancy.
b) P-value=0.07.
The P-value indicates that this sample result is not rare to happen (is greater than the significance level) even if the mean of the population is still 87 hours.
Step-by-step explanation:
We have to perform a hypothesis test on the mean, with known standard deviation of the population.
The null hypothesis, which we will reject or not, states that the life expectancy has not increase (it stays equal or less than 87 hours).
The null and alternative hypothesis are
The significance level is α=0.01.
The z-value is
The P-value for z is
The P-value (0.07) is greater than the significance level (0.01), so the effect is not significant. We fail to reject the null hypothesis.
There is no enough evidence of an increase in life expectancy.
Answer:
y=32x-32
Step-by-step explanation:
This time no algorithm or equation was needed i saw that if the equation was y=32x there would be ordered pairs (1,32) and (2,64) so to delay it by 1 on the x side just subtract the slope from the y - intercept sorry if that doesn't make sense
In this question we have to find an angle between 0 and 2π that is coterminal with 10pi/3 .
To find the coterminal angle, we need to subtract 2 pi from 10 pi/3. That is
Multiplying numerator and denominator of 2 pi by 3
And that's the required coterminal angle between 0 and 2pi.
