Answer:
We conclude that the question illustrates associative property.
Answer:
There is<u> no </u>sufficient evidence to support the claim that the bags are underfilled
Step-by-step explanation:
Null [H0] : chips x = 408
Alternate [H1] : chips x < 408
t = ( x' - u ) / (s / √n)
x' = sample mean , u = population mean, s = standard deviation, n = no. of observations.
(406 - 408) / (21 /√45)
-2 / 3.13
= 0.64
t value for α = 0.01 (one tailed), with degree of freedom = 44 : is 2.41
As calculated t 0.64 < tabulated t 2.41. So we don't reject the null hypothesis & state that chips x = 408
Answer:
7/10
Step-by-step explanation:
This is 7 / (3 + 7)
= 7/10
Step-by-step explanation:
let the eqn be y = mx + b.
m = (7 - 3)/(2 - 1) = 4
sub (1, 3):
3 = 4(1) + b
b = -1
therefore, equation is y = 4x - 1
