1. Li rolls a special dice that has 12 sides labeled 1 through 12, then flips a penny. What is the probability, written as a sim

jeka94

Answer:

1. The probability that she throws a multiple of 3 and flips tails is 1/6

2. The probability that Cymra draws a red marble put it back and draws a red marble again is 25/196

3. The probability that Cole flips three tails in a row, P(3T) is 1/8

4. The number of shots Linda is expected to make if she takes 175 shots is 56

Step-by-step explanation:

1. The number of sides on the special die Li rolls = 12 sides

The numbers on the die are 1 through 12

The number of faces on the penny = 2 (heads and tails)

The number of multiples of 3 on the die = 3, 6, 9, and 12 = 4

The probability that she throws a multiple of 3, P(3) = 4/12 = 1/3

The probability that she flips tails rather than heads = 1/2

∴ The probability that she throws a multiple of 3 and flips tails = 1/3 × 1/2 = 1/6

2. The number red marbles in the bag = 5

The number green marbles in the bag = 6

The number blue marbles in the bag = 3

The total number of marbles in the bag = 5 + 6 + 3 = 14

The probability that Cymra draws a red marble put it back and draws a red marble again is given as follows;

The probability with replacement of picking two red marbles = 5/14 × 5/14 = 25/196

3. The probability that Cole flips three tails in a row P(3T) = (1/2)×(1/2)×(1/2) = 1/8

The probability that Cole flips three tails in a row, P(3T) = 1/8

4. The percentage of times Linda makes her free throws in the past 5 basketball practices = 32%

The number of shots she is expected to make if she takes 175 shots = 175 × 32/100 = 56.

Given x^2 + y^2 = 36 and xy = -10 find x + y.

9966 [12]

This looks fun

ok so
we will use subsitution
xy=-10
divide both sides by x or y (I will choose y)
x=-10/y

sub -10/y fo x

(-10/y)^2+y^2=36
100/(y^2)+y^2=36
times both sides by y^2
100+y^4=36y^2
minus 36y^2 from both sides
y^4-36y^2+100=0
(y^2)^2-36(y^2)+100=0
quadratic formula
for
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$
x= $\frac{-(-36)+/- \sqrt{(-36)^2-4(1)(100)} }{2(1)}$
x= $18+/- 4\sqrt{14}$

sub
y=-10/x
y= $\frac{-10}{18+/- 4\sqrt{14}}$

so x+y= $18+/- 4\sqrt{14}$ + $\frac{-10}{18+/- 4\sqrt{14}}$
multiply first number by $\frac{18+/- 4\sqrt{14}}{18+/- 4\sqrt{14}}$ and add them

x+y= $\frac{(18+/- 4\sqrt{14})(18+/- 4\sqrt{14})-10}{18+/- 4\sqrt{14}}$
or
x+y= $\frac{81+22 \sqrt{14} }{5}$ or $\frac{81-22 \sqrt{14} }{5}$

What does the ratio 64:60 reduce to?

sesenic [268]

It would reduce to 16:15

They both share 4 as a common factor. 4 goes into 64, 16 times and 4 goes into 60, 15 times. Therefore allowing 64:60 to reduce to 16:15
