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
Answer:
no solutions
Step-by-step explanation:
|x+26| = -5
This has no solutions
Absolute value means positive and so the left side must be zero or greater
The right side is negative
This is never true, so there are no solutions
Look at it this way. (x.y x = 10 / y = 1) So, 3 inches straight is 15 * 3 = 45, and the 0.4 would be 45 + 4 = 49. So, 49 should be your answer.

Answer:
13. 60
15. 200
Step-by-step explanation:
These are the answers because:
1) Since they are asking us to round to the tens place or the hundreds place we have to look at the ones digit and the tens digit.
2) For 13, the answer is 60 because the rounding digit is 5. Since the digit is 5, we have to round up the digit in the tens place. Therefore, it becomes 60.
3) For 15, the answer is 200 because the rounding digit is 3. Since the digit is 3, we have to keep the same number. Therefore, the answer is 200.
Hope this helps!
