Step-by-step explanation:
Given:
population mean, mu = 57 lb
population standard deviation, sigma = 6.3 lb
Sample mean, x = 60.2 lb
Sample size, n= 45
Null hypothesis x = mu (i.e. sample mean is not greater than usual, using a significance level of 0.05)
Here we have a case where population mean and standard deviation are known (given).
We calculate the z-score
z=(x-mu)/(sigma/sqrt(n))
= (60.2-57)/(6.3/sqrt(45))
= 3.41
P(x>mu) = P(z>3.41) = 0.99968 >> 0.95 (one sided tail)
Therefore we can reject the null hypothesis and accept the alternate hypothesis that fish are larger than usual.
8 - 4m - 20 = 3m - 27
- 4m - 12 = 3m - 27
+4m +4m
- 12 = 7m - 27
+27 + 27
15 = 7m
m = 15/7
Well simply we need to understand how many feet there are in a yard
in this case
1 yard = 3 feet
1 foot = 12 inches
so 12 x 3 = 36
So the total perimeter of her scarf was 36 inches!
so some possible dimentions of her scarf could be 7 inches wide and 11 inches long.
if we check that
7 + 7 + 11 + 11 = 36!
so this is a correct possibility
