It will take 22 truck loads to haul all the dirt away.
42×29.7×8=9912
9912÷425.5=42 truckloads
Answer:
since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
Step-by-step explanation:
Given that the data in the question;
p" = 13/20 = 0.65
Now the test hypothesis;
H₀ : p = 0.9
Hₐ : p < 0.9
Now lets determine the test statistic;
Z = (p" - p ) / √[p×(1-p)/n]
= (0.65 - 0.9) /√[0.9 × (1 - 0.9) / 20]
= -0.25 / √[0.9 × 0.1 / 20 ]
= -0.25 / √0.0045
= -0.25 / 0.067
= - 3.73
Now given that a = 0.05,
the critical value is Z(0.05) = 1.645 (form standard normal table)
Now since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
Answer:

Step-by-step explanation:
<h2>
Answer: 600</h2>
Step-by-step explanation:
prime factorization of 75:
75 = 3 × 5 × 5
prime factorization of 120:
120 = 2 × 2 × 2 × 3 × 5
LCM = 2 × 2 × 2 × 3 × 5 × 5
There for the LCM = 600
* HOPEFULLY THIS HELPS:) Mark me the brainliest:)!!
Pennies are small so, if would be more accurate and have whole numbers. If u measured with an inch or meter, u would get a fraction for an answer.
