Let's say there were 3 questions with four answer choices each. That would mean there were 4*4*4 = 16*4 = 64 different ways to answer.
Extend this example out to 19 questions instead of 3. You'll get
4^19 = 4*4*4*...*4*4 = 274,877,906,944
The last value is one big number (not four numbers)
The large number is the answer
note: 4^19 means we have 19 copies of '4' being multiplied together. The three dots mean "continue the pattern". On your paper, you should somehow indicate to your teacher that there are 19 copies of '4' being multiplied.
Answer:
1 in =4 ft
Step-by-step explanation:
Divide 32by 8 and 40 by 10
Answer:
4/11
Step-by-step explanation:
Total number of marbles = 2(purple) + 4(white) + 3(blue) + 2(green)
= 11
Number of white marbles = 4
Probability of selecting a white marble =
number of white marbles/total number of marbles in the jar
= 4/11
Answer: the man's claim is true.
Step-by-step explanation:
Given that 30% of the well find water at a depth <=100 feet
P(X<=100) = 0.30
If the man's prediction work well the probability of finding well at less than 100 or equal should be high fwhen calculated from his results. So give 27 out of 80 wells
P(X<=100) = 27/80
P(X<=100) = 0.3375
Since 0.3375 > 0.3
The man's claim is true.
The answer would be B. Because the greater than/less than or equal to sign is always a colored in dot. And doing the math you’ll see that 5x < 20 and then you divide to get x < 4. Same with the other.
