Answer:
€445.5
Step-by-step explanation:
First we calculate the increase percentage and the increase.
Increase = 450 + (10%*450)
Now we must calculate the percentage of the increase.
Increase percentage = 10% of €450 = 450*0.1 = 45
Increase = 450 + 45 = €495
Since the decrease happens to the <em>new </em>number, the decrease and the decrease percentage <em>both </em>must be to the new changed number, which is 495
Decrease = 495 - (10%*495)
Again we must calculate the percentage of the decrease.
Decrease percentage = 10%*495 = 0.1*495 = 49.5
Decrease = 495 - 49.5 = 445.5
So, the value of Erika's ski chalet after the two changes = €445.5
A+7=0
A+7-7=0-7
A=-7
B+3=7
B+3-3=7-3
B=4
Answer:
<em>The probability that it would contain at least 6 letters is: </em><u><em>5/8</em></u>
<u><em></em></u>
Step-by-step explanation:
From the question given above,
We know that there are 8 planet that was given.
Mercury 7 letters
Venus 5 letters
Earth 5 letters
Mars 4 letters
Jupiter 7 letters
Saturn 6 letters
Uranus 6 letters
Neptune. 7 letters
Therefore,
P(at least 6 letters) + P( Less than 6 letters) = 1
P (at least 6 letters) + P (3 planet) = 1
P (at least 6 letters) + ( 3/8) = 1
P(at least 6 letters) = 1 - (3/8)
= 5/8
