Are the events "selecting a female" and "selecting a students who has brown eyes" independent?
Answers
Answer:
No, the events are not independent.
Step-by-step explanation:
Suppose that there are two events, A and B.
Such that first happens the event A and then the event B.
If the outcome of event A affects the probabilities for the different outcomes of event B, then the events are dependent.
In this case, if we have only the event "selecting a student who has brown eyes" (at random)
The probability is equal to the quotient between the total number of students with brown eyes, and the total number of students, then this probability is:
P = 91/200 = 0.455...
Now, if we first impose the "selecting a female", now when we want to select a student with brown eyes we will look only at the female students.
In this case, there are 32 with brown eyes and a total of 90 female students, then the probability of selecting a female with brown eyes at random is:
P = 32/90 = 0.355...
So the probability is different, which means that the events "selecting a female" and "selecting a student who has brown eyes" are not independent.

day, the store sold 9 baked goods for a total of $121. How many cakes did they sell?
a. 8 cakes
c. 7 cakes
b. 2 cakes
d. 4 cakes
Answers
Answer:
a. 8
Step-by-step explanation: Out of 12 baked goods sold , let the number of cakes sold, be x in number and pies sold were 12 − x in number. Total sell was $ 144 , 1 cake costs $ 14 and 1 pie costs, $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96 or 6 x = 48 ∴ x = 8

Answer:
y=2x-3
Step-by-step explanation:
y=mx+b
Where m is the slope and b is the y intercept
Slope is rise over run, the line is up 2 over 1
And the point of the line where it meets the y axis is -3. so b is -3

Law of Sines: B = arcsin[b·sinC/c} ≅ 38.4°
A = 180-C-B = 37.6°

A2. B = 56°, b = 17, c = 14
Law of Sines: C = arcsin[c·sinB/b] ≅43.1°
A = 180-B-C = 80.9°
Law of Sines: a = b·sinA/sinB ≅ 20.2
B1. B = 116°, a = 11, c = 15
Law of Cosines: b = √(a² + c² - 2ac·cosB) = 22.2

Marissa wrote her bike to the park and back up halfway to the park she stopped at the library she was one 310 miles from the library how many miles and miles to ride her bike and all now
Answers
Answer:
5 1/5 miles
Step-by-step explanation:
Given that :
Library is located halfway between park and home ;
Distance between library and park = 1 3/10 miles
Hence, total distance between park and home :
1 3/10 + 1 3/10 = 2 6/10
The distance driven :
Home to park ; park back home
2 6/10 + 2 6/10 = 4 12/10
4 + 12/10 = 4 + 1 2/10
= 5 2/10
= 5 1/5 miles

65/360 of that circumference is said to be 8
so we can solve x from

2πx = 8 · 360/65
πx = 288/13
x = 288 / (13π) ≈ 7.1

kim has 8 vanilla candles, 4 cherry candles and 6 raspberry candles. what is the probability that kim will choose a cherry candle?
Answers
-8 vanilla
-4 cherry
-6 raspberry
4/18 would represent the number of cherry candles. this could also be written as 22.22%, or just 22%
hope i was able to help you!
The probability that Kim will choose a cherry candle is [tex]\frac{2}{9}[/tex] OR 0.22
From the question,
We are to determine the probability that Kim will choose a cherry candle out of the possible candles
From the given information
Number of vanilla candles = 8
Number of cherry candles = 4
Number pf raspberry candles = 6
∴ Total number of candles = 8 + 4 + 6 = 18
Using the formula
[tex]Probability = \frac{Number\ of\ favorable\ outcomes}{Total\ number\ of\ outcomes}[/tex]
For the probability to choose cherry candle
Number of favorable outcome = 4
Total number number of outcomes = 18
∴ Probability of choosing cherry candle = [tex]\frac{4}{18}[/tex]
Probability of choosing cherry candle = [tex]\frac{2}{9}[/tex] OR 0.22
Hence, the probability that Kim will choose a cherry candle is [tex]\frac{2}{9}[/tex] OR 0.22
