Answer:
41
Step-by-step explanation:
Divide 2818 by 70 and it comes out to: 40.2571429 it is not 40 because their is still some left over so there will be 41 ferry's and one of them will not be a full ride!
Answer:
2z+6 or 2(z+3) are the equivalent expressions
Step-by-step explanation:
z+(z+6)
opening the brackets
z+z+6
=2z+6
or if we take 2 as common the answer is
=2(z+3)
i hope this will help you :)
Answer:
<h2>2/3</h2>
Step-by-step explanation:
This problem bothers on probability
Given that two dice are expected to give an outcome of sum greater than 8
But in the problem statement the first die is already settled since it is showing 6 already.
Now for the second die, the possible outcomes that will add up with the first die to produce a figure greater than 8 are (3,4,5,6)
The probability of obtaining either of these numbers is 4/6= 2/3
<em>Having the first die settled, this means that the probability of obtaining a sum of 8 is 2/3</em>

Since it is indicated that the sum of three consecutive odd integers is at most 216 and not exactly 216, the largest possible value of one of these integers is 73. The answer for this question would be option C. 69, 71, and 73 are the consecutive odd integers. Hope this answers your question.
Answer:
Yes, there is sufficient evidence to support the claim that the mean cost is $1.
Step-by-step explanation:
Data Given:
The population standard deviation 
= $0.2
The sample mean cost 
= $0.93
The sample size n = 12
From above we can use the Z-test for testing the mean from the above given data.
To check whether the mean cost of newspaper is $1.00
: 
= $1
: 
$1
The test statistics Z = 
Z = 
Z = -1.212
The P-value = 2P (Z< - 1.212)
= 2 × 0.1128
= 0.2256
Since the value of P is more than the significance level; do not reject the
Conclusion: We therefore conclude that there is sufficient evidence to support the claim that the mean cost is $1.
