Answer:
If that's the whole question then what exactly are we trying to solve here?
Step-by-step explanation:
The remaining number of flires that Linda still not posted is 40.
According to the given question.
The total number of fliers Linda have = 84
Fraction of fliers Linda posted = 1/3
And, fraction of fliers Linda posted second time from the remaning fliers = 2/7
Now,
1/3 of 84 fliers = 1/3 × 84 = 28
So, the number of fliers are left with Linda after first posting = 84 - 28 = 56
Again she posted 2/7 fliers. The number of flires Linda posted second time is given by
⇒ 2/7 × 56 = 16
Thereore, the number of fliers that Lindna still not posted = 56 - 16 = 40
Hence, Linda still not posted 40 fliers.

Answer:
See explanation below
Step-by-step explanation:
Here, a director of manufacturing must convince management that a proposed manufacturing method reduces costs before the new method can be implemented. The current production method operates with a mean cost of $220 per hour.
a) The alternative and null hypotheses would be:
H0: μ ≥ 220
Ha: μ < 220
b) Comment on the conclusion when H0 cannot be rejected:
When we fail to reject the null hypothesis H0, there is not enough evidence to conclude that the mean cost can be reduced from $220. Therefore the manager's proposed method cannot be implemented.
c) Comment on the conclusion when H0 can be rejected:
When the null hypothesis, H0 is rejected, there is enough evidence to conclude that the mean cost can be reduced from from $220. Therefore the manager's proposed method can be implemented.
Probability ( a flowering plant or fruit plant) is 
and Probability (neem plant or peepal plant) is 
.
Step-by-step explanation:
Given,
Number of neem plant = 125
Number of peepal plant = 165
Number of creppers plant = 50
Number of fruit plant = 150
Number of flowering plant = 110
To find the probability ( a flowering plant or fruit plant)
and probability ( neem or peepal)
Formula
P( A or B) = P(A) + P(B)
Probability ( a flowering plant or fruit plant) = 
= 
=
And,
Probability (neem plant or peepal plant) = 
= 
=
