8x = 64
x = 8
4x = 48
x = 12
10x = 80
x = 8
9x = 72
x = 8
So <span>4x = 48 is the only equation that is not satisfied the condition.</span>
Answer:
What the question .............
Answer:
0.60
Step-by-step explanation:
In the category of pets
22 students had a cat = P(C)
17 students had a dog = P(D)
9 students had both a dog and a cat = P(C and D)
The formula to find the Probability of two events =
P(C or D) = P(C) + P(D) - P(C and D)
P(cat or dog) = P(cat) + P( dog) - P(cat and dog)
P(cat or dog) = 22/50 + 17/50 - 9/50
P(cat or dog) = 0.44 + 0.34 - 0.18
P(cat or dog) = 0.60
The probability the student will have a dog or a cat is 0.60
Having a high interest rate doesn't make a bond higher risk. The cause and effect goes in the other direction: if a bond is higher risk, then investors demand a higher return.
Consider two investment choices: you could put $100 in a bank and get paid $1 interest, or you could gamble $100 on a game of chance that pays out $101 if you win, or nothing if you lose. Unless you're a gambling addict, you won't take the risk of losing your money when the safe alternative pays just as much. But if the game pays the winner $200, then you might be interested.
Likewise, companies that have a higher risk of defaulting need to promise a higher interest rate on their bonds in order to get anyone to choose them over safe investments.
