3p : 8s
1p : (8/3)s

So for every one 'p' there is (8/3) 's'

Ratio of p to s is 1 : 8/3

Please differentiate this problem

strojnjashka [21]

Answer:

dy/dx = d/dx sin(x-3/x+2)

dy/dx = cos(x-3/x+2) . d/dx (x-3/x+2)

dy/dx = cos(x-3/x+2) . (x + 2 - x + 3)/(x+2)²

dy/dx = [5cos(x-3/x+2)]/(x + 2)²

Martin earned the following scores on his last five tests.

98, 78 , 84, 75, 91

The interquartile range formula is the first quartile subtracted from the third quartile:

IQR = Q3 – Q1.

****************************************************
Step 1: Put the numbers in order.
75, 78, 84, 91, 98

Step 2: Find the median.
75, 78, 84, 91, 98

Step 3: Place parentheses around the numbers above and below the median. 
Not necessary statistically, but it makes Q1 and Q3 easier to spot.
(75, 78), 84, (91, 98)

Step 4: Find Q1 and Q3
Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.
(75, 78), 84, (91, 98)

*(75, 78) ---> (75 + 78) ÷ 2 = 76.5
*(91, 98) ---> (91 + 98) ÷ 2 = 94.5

Step 5: Subtract Q1 from Q3 to find the interquartile range.
94.5 – 76.5 = 18

IQR = 18

Two dice are rolled. What is the probability that the sum of numbers rolled is either 5 or 12?

Maksim231197 [3]

ANSWER:

The probability that sum of numbers rolled is either 5 or 12 is $\frac{5}{36}$

SOLUTION:

Given, Two dice are rolled.

We have to find what is the probability that the sum of numbers rolled is either 5 or 12

We know that, probability of an event = $\frac{\text { favourable outcomes }}{\text { total outcomes }}$

Now, total outcomes for two dices = 6 for 1st dice x 6 for 2nd dice = 6 x 6 = 36.

Now, favourable outcomes = sum is 5 + sum is 12

= 4[(1,4), (2,3), (3, 2), (4, 1)] + 1[(6,6)]

= 5 total favourable outcomes.

Now, probability = 5/36

Hence, the probability that sum is either 5 or 12 is 5/36.
