If each ribbon will be 3.68 inches, and she needs 1000 ribbons, then multiply the two to find the total length of ribbon she needs.
3.68 x 1000 = 3680
So she will need 3680 inches of ribbon in total
Answer:
Step-by-step explanation:
Refer to attached for points
a) f(-1) = 3 as per graph
b) f(x) = 6
We add horizontal line through point y=6 to find intersections with the graph
Take x-values of those points. The points are x = -3, x = -2, x = 2
Step-by-step explanation:
H0: u = 44.3
Hi : u# 44.3
Z1-0.05/2
Z1-0.025
Z0.975 = 1.96
Z = x-u/s.d/√n
Z= 44.4 -44.3/2.6/√130
Z = (0.1×11.4018)/2.6
Z=0.44
Since the calcalculated value is less than the table value and does not fall in the rejection region we fail to reject the null hypothesis
The value of 4 in 475 is 4 hundred
