Answer:
The two conditional probabilities are not equal because each has different given events. P(A|D) has event D as its given event, resulting in 2/10 for a probability. P(D|A) has event A as its given event, resulting in 2/8 for a probability.
Other part is:
different given events
P(A|D) equals 2/10
P(D|A) equals 2/8
The correct answer is:
3 1/2.
Explanation:
To find out how many 1/4 tsp doses are in 7/8 tsp of medicine, we divide:
7/8 ÷ 1/4
To divide fractions, flip the second fraction and multiply:
7/8 × 4/1
Multiply straight across:
7/8 × 4/1 = (7×4)/(8×1) = 28/8
To simplify this, we see how many times 8 will divide into 28. It divides evenly 3 times; this is our whole number.
After 8 goes into 28 3 times, there are 4 left over. This is the numerator of our fraction (8 is the denominator):
3 4/8 = 3 1/2
Answer:
The sum of 22 terms of given AP = 1562
Step-by-step explanation:
Formula:-
Sum of n terms of AP,
Sₙ= (n/2)[2a + (n - 1)d]
To find the sum of 22 terms
Here. a = 8, d = 6 and n = 22
Sₙ= (n/2)[2a + (n - 1)d]
S₂₂ = (22/2)[2*8 + (22 - 1)*6]
= 11[16 + 126] = 11 * 142 = 1562
Answer: I'm pretty sure its 1562
He is left with minutes for the last problem
Step-by-step explanation:
Given
Total time = 30 minutes
Time spent on problem 1: minutes
Time spent on problem 2: minutes
First of all, we will calculate the total time for 2 problems
The remaining time is:
Hence,
He is left with minutes for the last problem
