Answer:
D is correct
Step-by-step explanation:
Here, we want to select which of the options is correct.
The correct option is the option D
Since the die is unfair, we expect that the probability of each of the numbers turning up
will not be equal.
However, we should also expect that if we add the chances of all the numbers occurring together, then the total probability should be equal to 1. But this does not work in this case;
In this case, adding all the probabilities together, we have;
1/12 + 1/12 + 1/12 + 1/12 + 1/12 + 1/2
= 5(1/12) + 1/2 = 5/12 + 1/2 = 11/12
11/12 is not equal to 1 and thus the probability distribution cannot be correct
Answer:
The product of (x-3) and (x+7) is x² + 4x - 21
Step-by-step explanation:
The product of (x-3) and (x+7) is x² + 4x - 21
The product of (x - 3) and (x + 7) can be found as follows:
(x - 3)(x + 7)
open the bracket by multiplying
Therefore,
x(x) +x(7) - 3(x) - 3(7)
x² + 7x - 3x - 21
combine like terms
x² + 4x - 21
Answer:
2.71
Step-by-step explanation:
-y + (- z) + 7.99 =
= -(1.46) + [-(3.82)] + 7.99
= -1.46 - 3.82 + 7.99
= 2.71
Answer: DA:FA=KE:EF, DF:DA=KF:KE and FA:DA=EF:KE are correct.
Explanation: Since, 
and 
are similar triangles.
Because, 
and 
(because EA and KD are parallels. And, 
is common angle for these triangles.
Therefore, according to the property of similar triangles.
FE:EK= FA:AD, FE:FK=FA:FD and DF:DA=KF:KE .
Thus, first, second and third options are correct.
y = 12000x + 35000
When Mr. Nicolas began recording, it means, at 0 hour, how many tortillas was produced?
Subs x by 0.
y = 12000.0 + 35000
y = 0 + 35000
y = 35000
When Mr. Nicolas began recording the data, 35,000 tortillas had already been produced
The total number of tortillas produced 2 hours after the he began, it means, when x = 2
y = 12000 . 2 + 35000
y = 24000 + 35000
y = 59000
The total number of tortillas produced 2 hours after he began recording the data was 59,000
The total number of tortillas produced _ hours after he began recording the data was 85,000
Now we have y but not x.
y = 12,000x + 35,000
85,000 = 12,000x + 35,000
85,000 - 35,000 = 12,000x
50,000 = 12,000x
x = 50/12
x = 25/6
x = 4,1666...
Rounding
x = 4,167
