Answer:
Step-by-step explanation:
a)
p(d) - probability of a rivet being defective
p(r) - probability of seam needing to be reworked
The probability of the seem needing to be reworked is equal to the probability that ANY of 24 rivets is defective
Thus the probability that none of the 25 rivets is defective is 1-p(r)
p(r) = 16%, thus 1-p(r) = 84%
1-p(r) = (1-p(d))^24
0.84 = (1-p(d))^24
0.84^(1/24) = 1-p(d)
==> 1-p(d) = 0.9927615998
==> p(d) = 1-0.9927
==> p(d) = 0.0073
b) given p(r) = 8%, thus 1-p(r) = 92%
1-p(r) = (1-p(d))^24
0.92 = (1-p(d))^24
0.92^(1/24) = 1-p(d)
==> 1-p(d) = 0.99653179446
==> p(d) = 1-0.9965
==> p(d) = 0.0035
All you need to do is multiply the different types of each choice.
For salad, there are three different items. For entree, there are four different items. For side dish, there are three different items. for dessert, there are three different items.
Multiply the four numbers:
<u>108</u> dinner specials are possible.
Answer:
each person would get 4 with 4 left over

Answer:
<h2> 157 surveyed adult </h2>
Step-by-step explanation:
IF 22% of 714 surveyed adult made a statement, the actual number of those that made the statement can be gotten by simply evaluating 22% of 714 as shown below;
= 22% of 714
= 22/100 * 714
= (22*714)/100
= 15708/100
= 157.08
≈ 157 surveyed adult
<em>This means that about 157 surveyed adults made the statement. </em>
Answer:
c=93
Step-by-step explanation:
35+3(x+2)+52=180
87+3(x+2)=180
87+3x+6=180
93+3x=180
3x=180-93
3x=87
x=87/3
x=29
3(29+2)
3(31)=93
