Answer:
Sample Space:
1. (real, white)
2. (real, silver)
3. (real, gold)
4. (real, purple)
5. (fake, white)
6. (fake, silver)
7. (fake, gold)
8. (fake, purple)
Step-by-step explanation:
Nour and Rana each created a display to represent the sample space of randomly picking a type of tree and a color for the ornaments.
Whose display correctly represents the sample space?
We are not given their sample space but still you can compare the sample space you have with this one to find out whether it is correct or not.
There are 2 different types of Christmas trees
1. Real
2. Fake
There are 4 different types of colors for the ornaments
1. white
2. silver
3. gold
4. purple
The sample space is the set of all the possible outcomes of an experiment.
Then all of the possible outcomes are:
1. (real, white)
2. (real, silver)
3. (real, gold)
4. (real, purple)
5. (fake, white)
6. (fake, silver)
7. (fake, gold)
8. (fake, purple)
Therefore, there are total 8 possible outcomes.
Note: If your sample space matches with this one then it is correct otherwise it is not correct.
Answer:r/8>16
Step-by-step explanation:
Answer:
1231 ft
Step-by-step explanation:
Draw a right triangle. Label the height of the triangle. as 800 since the height of the triangle represents the height of the helicopter above the coast of the island. Label the base length of the triangle as d to represent the distance between the coast of the island and the coast of the mainland, P. The angle of depression from the helicopter to point P is 33° so draw a horizontal dotted line at the location of the helicopter and label the angle made by the horizontal line and the hypotenuse of the right triangle as 33°. The angle of elevation from P to the helicopter and the angle of depression from the helicopter to point P are congruent alternate interior angles so label the angle at P as 33°.
The side labeled 800 is opposite of P and the side labeled d is adjacent to P so you can use tangent to write an equation. Solve this equation for d and round to the nearest whole number.

1.155
Step-by-step explanation:
Answer:
The requirements for the hypothesis test does satisfied the method for testing the claim that from two population proportions the rate of polio is less for children given the salk vaccine.
Step-by-step explanation:
The percentage of children in the treatment group was:
(201229/401974)*100 = 49.9%
The percentage of children given placebo was:
(200745/401974)*100 = 50.1%
The percentage of children that developed polio in the treatment group:
(33/200745)*100 = 0.0164%
The percentage of children that developed polio in the placebo group:
(115/201229)*100 = 0.0571%
The percentage difference between the two group:
((0.0571-0.0164)/0.0571) = 61.62%
Therefore:
The amount of children used for each group was almost divided into half of the total amount of children. The test revealed although very small percentages of the both group developed polio, 68.62% more children given placebo than the children that was given the salk vaccine. Therefore, the study shows that the rate of polio is less for children given the salk vaccine and the the hypthesis test is satisfied.
