Answer:
Step-by-step explanation:
x - 2 (x - 
) = 2 (4 - x) + 10
x − 2 × 
=2(4−x)+10
x−(−x)=2(4−x)+10
x+x=2(4−x)+10
2x=2(4−x)+10
2x=8−2x+10
2x=−2x+18
2x+2x=18
4x=18
<span>After shuffling a deck of cards in order to know the probability of the king of spades being the top card, you have to first know how many cards are in the deck. If the card is a full deck with no jokers, then the probability is 1/52. This is also the probability that the bottom card is the King of spades.</span>
Answer:
Zscore = 0.5
Step-by-step explanation:
If we assume a normal distribution, we mean that the diameters of each tomato follow a normal distribution. This is N~ (0,1).
By that, we mean that the mean (μ) = 0 and variance (
) = 1. Thus, since we are told that one tomato was in the 50th percentile. This implies the median. And is 0.5. And if the distribution is normal, the mean and median and mode should be equal.
Thus:
==> Z score = 
= 
1kg=1000g so if it would be 80% it would be 20% left since 1000 is a proper percent we could determine that 800g
Is lost and we have 200g left or 2/10KG
