Answer:
Probabilities
Likely to happen (L) Unlikely to happen (U)
a. 4/5 5/8
b. 3/5 3/8
c. 4/5 4/7
d. 0.3 0.09
e. 5/6 and 4/5 2/3
Step-by-step explanation:
Probabilities in Percentages:
a. The probability of 4/5 = 80% and 5/8 = 62.5%
b. The probability of 3/8 = 37.5% and 3/5 = 60%
c. The probability of 4/5 = 80% and 4/7 = 57%
d. The probability of 0.3 = 30% and 0.09 = 9%
e. The probability of 2/3 = 67% and 4/5 = 80% and 5/6 = 83%
b) To determine the relative values of the fractional probabilities, it is best to reduce them to their fractional or percentage terms. When this is done, the relative sizes become obvious, and then, comparisons can be made.
the answer #1 is:40 tens and 3 ones
answer to #2 is: 50 tens and 5 ones
Answer:
a^ 17
Step-by-step explanation:
If the bases are the same,
We are multiplying, we can add the exponents
a^b* a^c = a^(b+c)
a^4 * a^3 * a^ 10
a^ (4+3+10)
a^17
"2x2 + 3x = −5" should be re-written as 2x^2 + 3x +5 = 0. This is a quadratic equation with a=2, b=3 and c=5. Thus, the roots are:
-3 plus or minus √(9-4[2][5])
x = ---------------------------------------------
4
or:
-3 plus or minus √(-31)
x = ----------------------------------
4
or:
-3 plus or minus i*√31
x = ----------------------------------
