Answer:
32.) Yes
33.) 7
34.) No because 40 is less than 50
Step-by-step explanation:
32.)
Were trying to see is 35 is 3/4ths of 50, so we set up a ratio and solve
[tex] \frac{3}{4} = \frac{x}{50} [/tex]
Next we cross multiply
[tex]4x = 150[/tex]
Lastly divide by 4
[tex]x = 37.5[/tex]
33.) We have to convert 2/5 and 5/6 into a value over 30.
For 2/5, 5 times 6 is 30. 2 times 6 is 12, so we get 12/30 playing Chess.
6 times 5 is 30. 5 times 5 is 25. Making it 25/50 playing Sudoku
[tex] \frac{12}{30} = chess \: \frac{25}{30} = sudoku[/tex]
Since 5 don't play sudoku and 18 don't play chess.
18+5 = 23...
30-23 = 7
34.) The picture to the right shows 20 stamps.
Two sheets of stamps means 20x2 = 40, which is less than 50

in a given population, 11% of the likely voters are african american. a survey using a simple random sample of 600 landline telephone numbers finds 8% african americans. is there evidence that the survey is biased? explain.
Answers
There is an evidence that suggest that the survey is biased because the proportion of African Americans in the population, in our test, is less than 11%.
Is there evidence that the survey is biased?To determine if the survey is biased, we can use hypothesis testing. Let's define our null hypothesis as: "the proportion of African Americans in the population is 11%". Let's define our alternative hypothesis as "the proportion of African Americans in the population is less than 11%".
We can then use a one-tailed z-test to test our hypothesis, with a significance level of 0.05. The formula for the test statistic is:
z = (p - P) / sqrt(P(1-P)/n)
Plugging in the values, we get:
z = (0.08 - 0.11) / sqrt(0.11(1-0.11)/600)
x = -2.23
Looking up the critical value for a one-tailed test with a significance level of 0.05, we find it to be -1.645. Since our calculated z-value (-2.23) is less than the critical value (-1.645), we reject the null hypothesis and conclude that there is evidence to suggest that the proportion of African Americans in the population is less than 11%.

7. to survey the opinions of bleacher fans at wrigley field, a surveyor plans to select every one-hundredth fan entering the bleachers one afternoon. will this result in a simple random sample of cub fans who sit in the bleachers?
Answers
The survey does not result in a simple random sample of Cubs fans who sit in the bleachers. So, option E) is correct.
Simple random sampling is a method of selecting a sample from a population such that each element in the population has an equal chance of being selected. This is achieved by using a random number generator or by randomly assigning a number to each element in the population and then selecting a sample based on those numbers.
In this case, the survey plan to select every one-hundredth fan entering the bleachers is not a simple random sample because not every sample of the intended size has an equal chance of being selected. For example, the first fan entering the bleachers has a 1 in 100 chance of being selected, while the second fan has a 2 in 100 chance of being selected. This creates a non-uniform selection process, which is not representative of simple random sampling.
Therefore, the survey plan to select every one-hundredth fan entering the bleachers results in a form of systematic sampling, which is not a simple random sample.

Complete Question: One afternoon, a surveyor intends to pick every fan entering the bleachers to get the views of those who sit in them at Wrigley Field. Will this lead to a straightforward random sample of Cubs supporters seated in the stands?
A. Yes, as each bleacher spectator has an equal chance of getting chosen.
B. The answer is yes, but only if the bleachers have a single entrance.
C. The control group will consist of the 99 out of 100 bleacher spectators who were not chosen.
D. The answer is "yes," as this is an illustration of systematic sampling, a subset of basic random sampling.
E. No, since there are unequal odds of selecting each sample of the intended size.
four cards are dealt from a standard deck with 52 cards (w/o replacement), one at a time. what is the chance that a heart turns up on the fourth card, but not before? group of answer choices
Answers
The probability of getting a heart on the fourth card but not before that is 0.2278
The probability of getting a heart on the fourth card can be calculated by multiplying the probability of not getting a heart in the first three cards by the probability of getting a heart on the fourth card.
The probability of not getting a heart in the first three cards can be calculated as follows:
(39/52) * (38/51) * (37/50) = 0.862
where 39/52 is the probability of not getting a heart on the first card, 38/51 is the probability of not getting a heart on the second card (given that no heart was drawn in the first card), and 37/50 is the probability of not getting a heart on the third card (given that no heart was drawn in the first two cards).
The probability of getting a heart on the fourth card can be calculated as follows:
13/49 = 0.265
where 13/49 is the probability of getting a heart on the fourth card (given that no heart was drawn in the first three cards).
So, the probability of getting a heart on the fourth card, but not before, can be calculated as:
0.862 * 0.265 = 0.2278
So, the chance of getting a heart on the fourth card, but not before, is approximately 22.78%.

Estefan brings two bags of sandwiches to a party. One bag contains 6 peanut butter sandwiches, 4 cheese sandwiches and 2 ham sandwiches. The other bag contains 4 peanut butter sandwiches, 2 cheese sandwiches, 4 ham sandwiches and 2 chicken salad sandwiches. If John picks one sandwich from each bag at random, what is the probability both will be peanut butter sandwiches? Express your answer as a common fraction
Answers
The number of peanut butter sandwiches in the first bag is 6 and in the second bag is 4. So, the probability of picking a peanut butter sandwich from each bag is 1/6.
The probability of an event happening is the number of successful outcomes divided by the number of total possible outcomes. In this case, there are two bags of sandwiches and John is picking one sandwich from each bag.
The first bag has 12 sandwiches in total, 6 of which are peanut butter. So, the probability of picking a peanut butter sandwich from the first bag is 6/12 or 1/2.
The second bag has 12 sandwiches in total, 4 of which are peanut butter. So, the probability of picking a peanut butter sandwich from the second bag is 4/12 or 1/3.
To find the probability of both sandwiches being peanut butter, you multiply the individual probabilities:
1/2 * 1/3 = 1/6.
So, the probability of both sandwiches being peanut butter is 1/6.

Answers
The exponential decay model for the investment of $38,976 with decreased rate 3.5% for 't' years is equal to option b. 38,976 (0.965 )^t.
Invested amount by Kindred = $38,976
Each year investment decreased by 3.5%
Number of years represented by 't' = 3 years
Amount decreased by 100 - 3.5% = 96.5%

Total amount decreased in three years = $38,976 × ( 0.965 )³
= $35,025.085
Exponential decay model for 't' years at the same rate is given by the equation :

A + B + C = Total
A + 2A + 3/2A = Total

Difference of two consecutive terms are related by :
dₙ = dₙ₋₁ + 1
Common difference is not same for all the terms so it is not arithmetic sequence.
