At a teddy bear workshop, customers can select from black, brown, gold, white, blue, or pink for their bear's colors. If a father randomly selects two bear colors, what is the probability that he will select a white bear for his son and a pink bear for his daughter? The father cannot pick the same color for both bears.
Answer:
[tex]P(White\ and\ Pink) = \frac{1}{30}[/tex]
Step-by-step explanation:
Given
Colors: Black, Brown, Gold, White, Blue, Pink
Required
P(White and Pink)
Since the father can not select the same color, then it is a selection without replacement.
So, we have:
[tex]P(White\ and\ Pink) = [P(White)\ and\ P(Pink)][/tex]
[tex]P(White\ and\ Pink) = [P(White)\ *\ P(Pink)][/tex]
This gives:
[tex]P(White\ and\ Pink) = [\frac{1}{6}\ *\frac{1}{6-1}][/tex]
[tex]P(White\ and\ Pink) = [\frac{1}{6}\ *\frac{1}{5}][/tex]
[tex]P(White\ and\ Pink) = [\frac{1}{30}][/tex]
[tex]P(White\ and\ Pink) = \frac{1}{30}[/tex]
Race organizers want to survey the participating runners on the difficulty of the running course. Which of the following most effectively uses cluster sampling?
Separate the runners into men and women, then randomly select 20 men and 20 women.
Organize the runners into groups (elite runners, fast runners, moderate runners, and walkers). Randomly select a group, and survey all the runners in that group.
Put the same number of marbles as runners into a bag, with 20 of the marbles being red. Have each runner select a marble from a bag at the finish line. If they choose a red marble, they take the survey.
Place the runners into groups based on the seconds part of their finishing time (0:00–0:05, 0:06–0:10, etc.). Randomly select 2 of these groups, and survey every runner within the chosen groups.
Answer: Place the runners into groups based on the seconds part of their finishing time (0:00–0:05, 0:06–0:10, etc.). Randomly select 2 of these groups, and survey every runner within the chosen groups.

Santosh spent $200, before tax, on a DVD player and DVDs. The player cost $120, new DVDs cost $15 and used DVDs cost $5. Santosh purchased the same number of new and uses DVDs. Write and solve an equation to find the number of each type of DVD Santosh purchased.
Answer:
Santosh purchased 4 new and 4 used DVDs.
Step-by-step explanation:
From the information given, as you know that Santosh spent $200 and that the DVD player cost $120, you can say that the new and used DVDs cost $80, which can be expressed as:
15x+5y=80, where:
x refers to the number of new DVDs
y refers to the number of used DVDs
Now, as the statement indicates that Santosh purchased the same number of new and used DVDs, this means that x is equal to y and you can replace y with x and solve for x:
15x+5x=80
20x=80
x=80/20
x=4
According to this, the answer is that Santosh purchased 4 new and 4 used DVDs.

Lily wants to ride her bicycle 43 miles this week. She has already ridden 16 miles. If she rides for 6 more days, what is the average number of miles she would have to ride each day to meet her goal?
Answer:
43-16=miles left to go. divide that by the 6 days left.
43-16= 27 miles.
27÷6= 4.5 miles per day
Answer:
4 1/2 miles
Step-by-step explanation:
43 - 16 = 27 miles remaining
27/6 = 4 3/6 or 4 1/2
Mrs. Tirado picked 5/6 pounds of lettuce from her garden. Mrs. Rampulla picked 2/3 less pounds than Mrs. Tirado. How much lettuce did they pick altogether?
Step-by-step explanation:
Total amount of lettuce = x pounds
Mrs. Tirado picked 5/6 pounds of lettuce from her garden.
5 / 6 * Total amount = 5/6 x
Mrs. Rampulla picked 2/3 less pounds than Mrs. Tirado.
Mrs. Rampulla = 2/3 (Mrs. Tirado) = 2/3 (5/6 x)
Mrs. Rampulla = 5/9 x
How much lettuce did they pick altogether?
Mrs. Rampulla + Mrs. Tirado
5/9 x + 5/6 x
(25/18) x pounds

Given:
Total number of students: T = 147
Number of students taking math : M = 95
Number of students taking science : S = 73
Number of students taking both math and science = 52
To find:
The theoretical probability of randomly choosing a student who is taking math.
Solution:
It is given that,
Total number of students (T) = 147
Number of students taking math (M) = 95
So, he theoretical probability of randomly choosing a student who is taking math is:
[tex]P(M)=\dfrac{\text{Number of students taking math}}{\text{Total number of students}}\times 100\%[/tex]
[tex]P(M)=\dfrac{95}{147}\times 100\%[/tex]
[tex]P(M)=64.62585\%[/tex]
[tex]P(M)\approx 64.6\%[/tex]
64.6% is the theoretical probability of randomly choosing a student who is taking math.
Hence, option C is correct.

Two angles in a triangle measure 102° and 670. What is the measure of the third angle?
0 110
0789
1139
O 169°
Step-by-step explanation:
step 1. wow! 670° I think you mean 67°
step 2. the 3 internal angles of a triangle add up to 180°. let x be the third angle
step 3. x + 102 + 67 = 180
step 4. x + 169 = 180
step 5. x = 11°.
