Answer:
139
Step-by-step explanation:
supplementary angles add up to 180o
180-41=139
Answer:
2 and 10
Step-by-step explanation:
Let x be length of the small piece and y the length of the big one.
● y = 5x
Since the big piece is 5 times longer than the short one.
The total length is 12 ft
● y + x = 12
● 5x + x = 12
● 6x = 12
Divide both sides by 6
● 6x/6 = 12/6
● x = 2
So the length of the two pieces are 2 ft and 10 ft (5×2)
Answer:
The correct system would be B
Step-by-step explanation:
The reason that it is B, is that we would first need an equation for the total number of baskets he made. In this one, we need the two pointers added to the three pointers to get the total of 65
w + t = 65
The second equation needs to be the total number of points (151). That should be equal to the value of the shot times the amount of them made.
2w + 3t = 151
This is option B, and is therefore the answer.
Answer:
0.0319
Step-by-step explanation:
To approximate this probability, we shall be using the Bernoulli approximation of the Binomial distribution.
Let p = probability of selecting a reference book = 65% = 0.65
Let q = probability of selecting other books= 1-p = 1-0.65 = 0.35
Now, we want to find the probability that all of these 8 books to be re-shelved are reference book.
We set up the probability as follows;
P(X = 8) = 8C8 •p^8•q^0
P(X = 8) = 1 * (0.65)^8 * (0.35)^0
P(X = 8) = 0.031864481289 which is 0.0319 to 4 decimal places
