Answer:

3/2 or 1.5

Step-by-step explanation:

Multiply 3/5 by 2 to make the denominator of both fractions equal.

A large t-statistic indicates a greater difference between the sample means and provides stronger evidence for a significant difference between the populations.

The t-statistic is a measure of the difference between two sample means relative to the variability within the samples. When the population means are different, the difference between the sample means will tend to be larger, which will result in a larger numerator in the t-statistic formula. The larger the difference between the sample means, the greater the evidence for a difference between the populations. In contrast, if the population means are similar, the difference between the sample means will be smaller, resulting in a smaller numerator and a weaker test of significance.

The denominator of the t-statistic formula is the standard error of the mean, which measures the variability of sample means around the population mean. If the sample size is large enough, the standard error of the mean will be small, resulting in a smaller denominator and a larger t-statistic. Therefore, when the population means are different, a larger t-statistic would be expected due to a combination of a larger numerator and a smaller denominator.

In summary, If the population means are different, a large t-statistic would be expected.

When the mean number of points scored per game next season is 60, the model predicts that the mean home attendance will be 11902

The function that predicts the attendance is given as:

\(y = -7628+325.5x\)

When the mean number of points scored per game next season is 60, it means that the value of x is 60

i.e. x = 60

Substitute 60 for x in the function

So, we have:

\(y = -7628+325.5 \times 60\)

Evaluate the product

\(y = -7628+19530\)

Add -7628 and 19530

\(y = 11902\)

Hence, the model predicts that the mean home attendance will be 11902

\(z = \frac{4x}{3y}\)

Step-by-step explanation:

\(x = \frac{3yz}{4}\)

\(3zy = 4x\)

\(z = \frac{4x}{3y}\)

Answer:

z = (4x)/(3y)

Step-by-step explanation:

Given equation,

→ x = (3yz)/4

Now the value of z will be,

→ x = (3yz)/4

→ (3yz)/4 = x

→ 3yz = x × 4

→ z × 3y = 4x

→ [ z = 4x/3y ]

Hence, value of z is 4x/3y.

Sophia has 5 cards numbered 1, 3, 5, 7, and 9. To form a 3-digit number, the number formed should be divisible by 3.

For a number to be divisible by 3, the sum of its digits must be divisible by 3. In this case, Sophia needs to select three cards from the given set and form a number.

To calculate the number of 3-digit numbers divisible by 3, we can use the concept of combinations. The total number of combinations of selecting 3 cards out of 5 is given by the formula \(\displaystyle\sf \binom{n}{r}=\dfrac{n!}{r!(n-r)!}\), where \(\displaystyle\sf n\) is the total number of items and \(\displaystyle\sf r\) is the number of items to be selected.

Using this formula, the number of ways Sophia can select 3 cards out of the given 5 is \(\displaystyle\sf \binom{5}{3}=\dfrac{5!}{3!(5-3)!}\).

Simplifying, we have \(\displaystyle\sf \binom{5}{3}=\dfrac{5\times 4\times 3!}{3!\times 2!}\).

Canceling out the common terms, we get \(\displaystyle\sf \binom{5}{3}=\dfrac{5\times 4}{2\times 1}=10\).

So, Sophia can make 10 different 3-digit numbers using the given cards.

Step-by-step explanation:

The radius of convergence is 28pr and the interval of convergence is [-28pr, 28pr].

In order to find the radius of convergence of the series, we will use the ratio test. If a series, ∑an, satisfies the following: \(limn→∞|an+1/an|=l\) (exists and is finite)Then the series converges if l < 1 and diverges if l > 1. If

l = 1, then the test is inconclusive. The given series is

\(∑n=k∞(−1)n(x+10n/2)/28pr\). Let's apply the ratio test to find the radius of convergence of the series.

\(|(an+1)/(an)| = |(−1)n+1(x+10(n+1)/2)/28pr|/|(−1)n(x+10n/2)/28pr|\) Note that the absolute value of the denominator will always be 1 because \((-1)^n\) is either 1 or -1.

Hence, we can simplify the above expression to:\(|(x + 10(n + 1)/2)/28pr|\) Let l be the limit of the above expression as n approaches infinity. Then, \(|x/28pr + 10(n + 1)/2(28pr)|/|10n/2(28pr)|=|x/28pr + 10/2(28pr)(n +\) \(1)/10/2(28pr)n||x/28pr + 5/28pr(n + 1)/n|limn→∞|x/28pr + 5/28pr(n + 1)/n| = |x/28pr|\) Therefore, the radius of convergence is 28pr and the interval of convergence is [-28pr, 28pr].

The distance between two points is the number of units between them.

The distance between Q and R is 3.61 units

It is impossible to determine your friend's error, because the steps are not given in the question. So, I will calculate the distance between Q and R, instead.

The distance (d) between two points is:

\(d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\)

So, the distance QR is:

\(QR = \sqrt{(1 - 3)^2 + (5 - 8)^2}\)

\(QR = \sqrt{(- 2)^2 + (- 3)^2}\)

Evaluate exponents

\(QR = \sqrt{4 +9}\)

\(QR = \sqrt{13}\)

Take square root of 13

\(QR = 3.61\)

Hence, the distance between Q and R is 3.61 units

Step-by-step explanation:

I got it right on my quiz

a) U is subspace of R^3.

b) The set {(3, -2, 0), (0, 1/2, 1)} is a basis for U.

c) 2.

a) To show that U is a subspace of R^3, we need to verify the following three conditions:

i) The zero vector (0, 0, 0) is in U.

ii) U is closed under addition.

iii) U is closed under scalar multiplication.

i) The zero vector is in U since 0 + 2(0) - 3(0) = 0.

ii) Let (x1, y1, z1) and (x2, y2, z2) be two vectors in U. Then we have:

x1 + 2y1 - 3z1 = 0 (by definition of U)

x2 + 2y2 - 3z2 = 0 (by definition of U)

Adding these two equations, we get:

(x1 + x2) + 2(y1 + y2) - 3(z1 + z2) = 0

which shows that the sum (x1 + x2, y1 + y2, z1 + z2) is also in U. Therefore, U is closed under addition.

iii) Let (x, y, z) be a vector in U, and let c be a scalar. Then we have:

x + 2y - 3z = 0 (by definition of U)

Multiplying both sides of this equation by c, we get:

cx + 2cy - 3cz = 0

which shows that the vector (cx, cy, cz) is also in U. Therefore, U is closed under scalar multiplication.

Since U satisfies all three conditions, it is a subspace of R^3.

b) To find a basis for U, we can start by setting z = t (where t is an arbitrary parameter), and then solving for x and y in terms of t. From the equation x + 2y - 3z = 0, we have:

x = 3z - 2y

y = (x - 3z)/2

Substituting z = t into these equations, we get:

x = 3t - 2y

y = (x - 3t)/2

Now, we can express any vector in U as a linear combination of two vectors of the form (3, -2, 0) and (0, 1/2, 1), since:

(x, y, z) = x(3, -2, 0) + y(0, 1/2, 1) = (3x, -2x + (1/2)y, y + z)

Therefore, the set {(3, -2, 0), (0, 1/2, 1)} is a basis for U.

c) Since the basis for U has two elements, the dimension of U is 2.

The equation of a line in the slope intercept form is expressed as

y = mx + c

The given equation is

9x + 3y = 18

We would rearrange it so that it takes the form of the slope intercept equation shown above.

We would divide both sides of the equation by 3, we have

9x/3 + 3y/3 = 18/3

3x + y = 6

Subtracting 3x from both sides of the equation, we have

3x - 3x + y = 6 - 3x

y = 6 - 3x

The slope intercept form is

y = - 3x + 6

To plot the graph, we would substitute values of x into the equation to get corresponding y values. These x and y values would be plotted on the x and y coordinates of the graph. We have

For x = - 2, y = 6 - 3(- 2) = 6 + 6 = 12

For x = - 1, y = 6 - 3(-1) = 6 + 3 = 9

For x = 0, y = 6 - 3(0) = 6 - 0 = 6

For x = 1, y = 6 - 3(1) = 6 - 3 = 3

For x = 2, y = 6 - 3(2) = 6 -6 = 0

The graph is shown below
