Answer: The area of the composite figure is 392.12cm^{2}.
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
36 x 8 = ( ___ + 6) x 8
36 - 6 = 30
36 x 8 = ( 30 + 6) x 8
36 x 8 = 36 x 8
288 = 36 x 8
288 = 288
Answer:
y = 2
Step-by-step explanation:
y varies inversely with x setup is:
y = k/x
7 =
(find 'k')
k = 7/1 · 2/3
k = 14/3
use what you know about 'k' and 'x' to solve for 'y'
y = 14/3 ÷ 7/3 (remember to multiply by the reciprocal when dividing fractions)
y = 14/3 · 3/7
y = 2
Answer:
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447 gram setting.

Mean = 
n = 19
Since n < 30 , so we will use t test

Substitute the values :


t calculated = -0.830
degree of freedom = n-1 = 19-1 = 18
A level of significance=α=0.025

t critical = 2.093
t calculated < t critical
So, We failed to reject null hypothesis
Decision rule -0.830< 2.093 So, We failed to reject null hypothesis
I think the 57 is an whole number.
