When 1 is divided into 8 pieces, each piece is 1/8 of the whole.
Answer:
<h2>C
. 7 units</h2>
Step-by-step explanation:
The question is lacking appropriate diagram. Find the diagram to the question attached.
From the diagram, it can be seen that AD = AB+BC+CD
Given the following
AD = 23units
AB = 4units
CD = 12units
To get C=BC, we will substitute the given segments into the expression above as shown;
23 = 4+BC+12
23 = BC + 4 + 12
23 = BC+16
Subtract 16 from both sides
23-16 = BC+16-16
7 = BC
<em></em>
<em>Hence the length of segment BC is 7units.</em>
Answer:
the probability that more than 70% of customers in the sample will need additional maintenance is 0.0371
Step-by-step explanation:
From the information given:
we are to determine the probability that more than 70% of customers in the sample will need additional maintenance
In order to achieve that, let X be the random variable that follows a binomial distribution.
Then X
Bin(48, 0.6)
However 70% of 48 samples is
= 0.7 × 48 = 33.6
34
Therefore, the required probability is:
= P(X> 34)



= 0.03709524328
0.0371
Answer:
0.185 Step-by-step explanation:
(2.4 x 10^-1) - (5.5 x 10^-2)
