Answer:
C) It is not possible. He needs to lose at least 5 lbs a week
Step-by-step explanation:
This would not be possible. To know, you have to plug 10 into the function:
-4(10) + 250 = 210
After getting this value, ou have to take it away from 250:
250 - 240 = 40 → This 40 represents the value for the amount of pounds lost
40 is less than 50, so he would have to lose more than 4 pounds a week
To see if losing 5 pounds is enough, replace the -4 from the function with a -5:
-4x + 250 = 210 → -5x + 250 = 210
From here plug in 10 just like the previous time:
-5(10) + 250 = 200
From here take 200 away from 250 to find the pounds lost in 10 weeks:
250 - 200 = 50
50 is equal to the goal of 50 pounds, so therefore, Luke needs to lose at 5 pounds a week
if the area is 16cm squared the diameter would be 4.51cm
The radius is half the diameter which would be 2.255cm
Answer:
0.1384
Step-by-step explanation:
Using binomial probability:
P = nCr p^r q^(n-r)
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Given n = 25, r = 4, p = 0.10, and q = 0.90:
P = ₂₅C₄ (0.10)⁴ (0.90)²⁵⁻⁴
P = 12650 (0.10)⁴ (0.90)²¹
P = 0.1384
