The probability that all four cards drawn from a deck are black cards is 1/4165.

There are 26 black cards and 52 cards in a standard deck of cards. Therefore, the probability of drawing a black card from a standard deck of cards is 26/52 or 1/2. In the first draw, there are 26 black cards out of 52 cards, so the probability of drawing a black card is 26/52.

In the second draw, there are 25 black cards left out of 51 cards, so the probability of drawing a black card is 25/51. In the third draw, there are 24 black cards left out of 50 cards, so the probability of drawing a black card is 24/50. In the fourth draw, there are 23 black cards left out of 49 cards, so the probability of drawing a black card is 23/49.

Using the multiplication principle of probability, the probability that all four cards drawn from a deck are black cards is 26/52 × 25/51 × 24/50 × 23/49 = 1/4165.

Answer:

The constant between two consecutive terms is called the common difference. The common difference is the number added to any one term of an arithmetic sequence that generates the subsequent term.

Answer:

c. infinitely many solutions

Answer:

152

Step-by-step explanation:

this is an arithmetic sequence, since the gap between values is the same (-2 - -9 = 7, 5 - -2 = 7......)

the first value, a, is -9. the common difference is 7. n is position in sequence.

formula for arithmetic sequence = a + (n-1)d

= -9 + (n-1) 7

= -9 + 7n -7

=7n -16.

so the 24th term is 7(24) - 16

= 152.

We can use similar methods to rewrite the expressions in problems 19 through 22 as single power series.

To rewrite each of the expressions in problems 18 through 22 as a single power series whose generic term involves xn, we can use the formula for a geometric series. This formula states that a geometric series with first term a and common ratio r can be expressed as:

a + ar + ar² + ar³ + ...

We can rewrite this formula in terms of xn by letting a = f(21) and r = (x - 21)/21. Then, the nth term of the series is given by:

f(21) ˣ [(x - 21)/21]^n

Using this formula, we can rewrite each of the given expressions as a single power series whose generic term involves xn.

For example, in problem 18, we are given the expression:

f(x) = 1/(x² - 4x + 3)

We can factor the denominator as (x - 1)(x - 3) and write:

f(x) = 1/[(x - 1)(x - 3)]

Using partial fractions, we can express f(x) as:

f(x) = 1/(2(x - 1)) - 1/(2(x - 3))

Now, we can use the formula for a geometric series with a = 1/2, r = (x - 21)/21, and n = k - 21 to write:

f(x) = 1/2 ˣ [(x - 21)/21]²¹ - 1/2 * [(x - 21)/21]²³ + ...

This is a single power series whose generic term involves xn. We can use similar methods to rewrite the expressions in problems 19 through 22 as single power series.

Answer:

\(\frac{2}{n}\)

Step-by-step explanation:

\(\frac{2n}{n^2}\) (exponential rule for fraction is the number subtract each other)

\(2n^{-1}\) (from the top n exponent of 1 minus bottom exponent of2 (1-2=-1))

since the n is a -1 exponent to make it positive you put it in the denominator

\(\frac{2}{n}\)

(the reason it's not n/n^2 is that the two cannot just disappear or be taken away unless you are solving for something and the n/n^2 can also be simplified into the 1/n)

Answer:

38

Step-by-step explanation:

x² + 2y ÷ 2w + 3z if (w = 2) (x = 5) (y = 8) (z = 3)

Now switch the letters with the numbers that it was given

x² is (5²)

2y is (2 * 8)

2w is (2 * 2)

3z is (3 * 3)

Put these in the equation

5² + (2 * 8) ÷ (2 * 2) + (3 * 3)

Solve what is inside the parenthesis

5² + (16) ÷ (4) + (9)

get rid of the parenthesis

5² + 16 ÷ 4 + 9

Now solve it from here

5² "(5 * 5)" = 25

25 + 16 ÷ 4 + 9

you want to divide 4 into 16 first because of PEMDAS

25 + 4 + 9

Using Pearson's correlation coefficient test is an effective way to determine if there is a relationship between two variables, and can help inform decisions and policies related to education and employment.

To test for a correlation between subjects' level in college and their annual income, you would use a correlation coefficient test. Specifically, you would use Pearson's correlation coefficient test, which measures the strength and direction of the linear relationship between two variables. In this case, the two variables are the level in college (Freshman, Sophomore, Junior, Senior) and annual income in dollars.

Pearson's correlation coefficient ranges from -1 to 1, where a value of -1 indicates a perfect negative correlation (i.e., as one variable increases, the other decreases) and a value of 1 indicates a perfect positive correlation (i.e., as one variable increases, the other also increases). A value of 0 indicates no correlation between the two variables.

Once you have collected data on the subjects' level in college and annual income, you can calculate Pearson's correlation coefficient using statistical software or a calculator. If the correlation coefficient is significantly different from 0 (i.e., there is a correlation between the two variables), you can then interpret the strength and direction of the correlation to determine how the level in college relates to annual income.

The inductive hypothesis is used in step C.

In step C, the inequality "100k + 100k > 100(k + 1)" is obtained by adding 100k to both sides of the inequality in step B.

The inductive hypothesis is that the inequality "2^k > 100k" holds for some value k. By using this hypothesis, we can substitute "2^k" with "100k" in step B, which allows us to perform the addition and obtain the inequality in step C.

We can think of the ANOVA test as examining a relationship between an explanatory variable that is categorical and a response variable that is continuous.

The categorical variable is often referred to as a factor or a grouping variable, while the continuous variable is typically the outcome or dependent variable.

In the ANOVA test, we compare the means of multiple groups or populations. The groups can represent different levels or categories of the explanatory variable.

The goal is to determine if there is a significant difference in the means of these groups, which would indicate that the explanatory variable has an effect on the response variable.

By conducting an ANOVA test, we are essentially comparing the variation between the group means to the variation within each group.

If the variation between the group means is much larger than the variation within each group, it suggests that the groups have different population means.

The ANOVA test allows us to make inferences about the population means based on the sample means. By comparing the means of multiple groups, we can assess if there is evidence to suggest that the means are not all equal.

If the ANOVA test results in a statistically significant difference, we can further explore pairwise comparisons to determine which specific groups have different means.

In summary, the ANOVA test helps us examine the relationship between a categorical explanatory variable and a continuous response variable, and it allows us to compare the means of different groups to assess if there are significant differences among them.

False, r2adj is the adjusted coefficient of determination that can exceed r2 if there are several weak predictors.

R2adj is the adjusted coefficient of determination and takes into account the number of predictors in the model. It penalizes the addition of insignificant predictors that do not improve the model fit.

R2, on the other hand, is the coefficient of determination and measures the proportion of variability in the dependent variable that is explained by the independent variables in the model.

It is possible for R2 to increase when weak predictors are added, but this increase is not necessarily mean that the predictors do not have a significant impact on the outcome.

The average speed for the downhill section must be 20 km/hour

Let's call the average speed for the uphill section "u" and the average speed for the downhill section "d". The total average speed for the 20 km section must be 20 km/hour, so we can set up an equation:

\((10 km / u) + (10 km / d) = 20 km / 20 km/hour\)

We know that the average speed for the uphill section is 12 km/hour, so we can substitute this value into the equation:

\((10 km / 12 km/hour) + (10 km / d) = 20 km / 20 km/hour\)

Simplifying the equation:

\(5/6 + 10/d = 1\)

\(5/6 = 1 - 10/d\)

\(d = 20 km/hour\)

So the average speed for the downhill section must be 20 km/hour in order for the average speed for the entire trip to be 20 km/hour.
