Um I dont know the specific expression. But I think one of them would be 6p + 1p = 7p. I know its really simple but its kinda right. Hope I can help. Sorry If im wrong
241.67%. Hope this helps.
Answer:
10 mph
Step-by-step explanation:
50 divided by 5 is 10
We have been given that the average age of a breed of dog is 19.4 years. The distribution of their ages is normal and 20% of dogs are older than 22.8 years. We are asked to find the standard deviation.
Since 20% of dogs are older than 22.8 years, so 80% of dogs are younger than 22.8.
We will use z-score formula to solve our given problem.
, where,
z = z-score,
x = Random sample score,
= Mean,
= Standard deviation.
Now we will use normal distribution table to find the z-score corresponding to 80% or
.
z-score corresponding to 0.80 is 0.845.
Upon substituting our given values in z-score formula, we will get:





Therefore, the standard deviation is approximately 4.02 years.
Answer:
B
Step-by-step explanation:
Since x= 3/4
To take the fraction on left hand side, inverse 4/3
Take π as denominator
Then cube root the entire equation on the left hand side.
