Answer: C) 25
Step-by-step explanation:
x²+10x+ __=16+ __
Only the square of 5, 5², which is 25, can make the two factors plus equal to 10x, so we need to add 25.
The probability of selecting two jelly-filled donuts in a row is 1/ 22
<h3>What is probability?</h3>
Probability is simply the chance that a given event will occur.
It is also the ratio of the number of outcomes in a set of equally likely outcomes that produce a given event to the total number of possible outcomes.
From the information given, we have that the donuts are:
- 6 are jelly-filled
- 10 are lemon-filled
- 8 are custard-filled
Note that two jelly - filled donuts were taken without replacement
Probability( 2 jelly -filled donuts) = 6 / 24 × 4/ 22 = 24/ 24 × 22 = 1/ 22
Thus, the probability of selecting two jelly-filled donuts in a row is 1/ 22

Time taken, t = 6:00 - 2:00 = 4 hour.
We know,
Therefore, the half-life of the isotope is 1.024 hours.
Hence, this is the required solution.
Positive integer: 2
2*2 = 4
4 + 6 = 10
10/2 = 5
5-2 = 3
Y=6*4^x = 6*4^-3=6*0.015625=0.09375
