In conclusion, to compute the chi-square value, we need to know the number of categories and use the appropriate formula or table to find the critical value. The degrees of freedom (df) will be equal to the number of categories minus one (df = k-1).

In the given question, we need to compute the chi-square value to determine the upper bound of the interval. The chi-square value depends on the degrees of freedom (df). To calculate it, we need to know the significance level (α) and the number of categories (k).

Since the question does not provide information about the number of categories, we cannot determine the exact degrees of freedom. However, we can assume that the number of categories is given, and proceed accordingly.

Assuming k is the number of categories, the degrees of freedom (df) will be (k-1).

For example, if there are 5 categories, the degrees of freedom will be (5-1) = 4.

The chi-square value is computed using a chi-square distribution table or a calculator. By using the significance level (α) and the degrees of freedom (df), we can determine the critical value.

In conclusion, to compute the chi-square value, we need to know the number of categories and use the appropriate formula or table to find the critical value. The degrees of freedom (df) will be equal to the number of categories minus one (df = k-1).

The Ratio Test cannot be used to determine whether the given series is convergent or divergent. The evaluation of the limit resulted in 1, which does not provide any information about the convergence or divergence of the series.

To determine whether the series is convergent or divergent, we can use the Ratio Test. Using the terms given in the question, we can write:
an = 8n
an+1 = 8(n+1)
Using these expressions, we can evaluate the limit:
lim n → [infinity]  (an+1/an)
= lim n → [infinity]  (8(n+1)/8n)
= lim n → [infinity]  (n+1)/n
We can simplify this expression by dividing both the numerator and denominator by n:
lim n → [infinity]  (n/n + 1/n)
= lim n → [infinity]  (1 + 1/n)
As n approaches infinity, the expression (1/n) approaches zero, so we have:
lim n → [infinity]  (1 + 1/n) = 1
Since the limit is equal to 1, we cannot make any conclusion about the series using the Ratio Test. We would need to use another test, such as the Comparison Test or the Limit Comparison Test, to determine whether the series is convergent or divergent.
In conclusion, the Ratio Test cannot be used to determine whether the given series is convergent or divergent. The evaluation of the limit resulted in 1, which does not provide any information about the convergence or divergence of the series.

70 different divisions are possible when eight children are divided into two teams each containing 4 children to play a game against each other

so this is what's known as a combination. a combination is a group where the order does not matter. to solve a combination, you use this equation:

n! / (r! *(n-r)!)

n is the total number of objects being sorted (8)

r is the group you need to sort them into (4)

(i know it's 2 groups of 4 but if you solve this for 1 group, the other group is automatically made of the remaining kids)

definition of !:

a number with a ! means 1*2*3...*that number (so that number multiplied by every number smaller than it all the way to one)

so we put 8 and 4 in this equation:

8! / (4! *(8-4)!)

simplify:

8! / *(4! 4!)

multiply out:

(8*7*6*5*4*3*2*1) / (4*3*2*1 * 4*3*2*1)

and put that in your calculator

Answer:

In particular, for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions.

Step-by-step explanation:

The probability that a customer who paid with a credit card bought premium gas is 0.205.

We need to use Bayes' theorem to find the required probability. Let P(P) be the probability that the customer bought premium gas, and P(C) be the probability that the customer paid with a credit card.

We know that:

We want to find P(P|C), which is the probability that the customer bought premium gas given that she paid with a credit card.

Using Bayes' theorem, we have:

\(P(P|C) = \frac{P(C|P) \cdot P(P)}{P(C)}\)

We can find P(C) using the law of total probability:

P(C) = P(C|R) . P(R) + P(C|M) . P(M) + P(C|P) . P(P)

Substituting the given values, we get:

P(C) = 0.28 * 0.88 + 0.34 * 0.02 + 0.42 * 0.10 = 0.3036

Now, substituting P(C|P) = 0.42 and P(P) = 0.10, we get:

\(P(P|C) = \frac{0.42 \cdot 0.10}{0.3036} = 0.205\)

Therefore, the probability that a customer who paid with a credit card bought premium gas is 0.205 (rounded to 3 decimal places).

The complete question:

In a recent month, 88% of automobile drivers filled their vehicles with regular gasoline, 2% purchased midgrade gas, and 10% bought premium gas. Of those who bought regular gas, 28% paid with a credit card; of customers who bought midgrade and premium gas, 34% and 42%, respectively, paid with a credit card. Suppose we select a customer at random. Given that the customer paid with a credit card, find the probability that she bought premium gas.

The values of the dependent variable associated to corresponding linear equations are listed below:

Herein we find two cases of linear equations in slope-intercept form, in which we need to clear the independent variable (x) associated to given values in the dependent variable (y). The equation of the line in slope-intercept form is described below:

y = m · x + b

Where:

By algebra properties, the value of the independent variable can be defined by the following expression:

x = (y - b) / m

Now we proceed to determine the values of x:

Case 1: y = - x - 14, y = - 2

x = (- 2 + 14) / (- 1)

x = - 12

Case 2: y = - (3 / 2) · x - 9, y = - 48

Step-by-step explanation:

Volume of sphere 4/3 *pi*r^3

Let small sphere radius r1=r

So radius of large sphere R= 2r (given)

Put all valves in sphere formula and calculate

Small sphere vol v1 = 4/3*pi*r^3......... Let assume eq 1

Large sphere vol= 4/3*pi*(2r)^3

= 4/3*pi* 8r^3

Or = 8v1

substitute 4/3*pi*r^3 value from eq1

Answer:

8

Step-by-step explanation:

Given the ratio of the radii = a : b, then

ratio of volume = a³ : b³

Here the ratio of radii = 1 : 2 , thus

ratio of volume = 1³ : 2³ = 1 : 8

That is the volume of the larger sphere is 8 times the volume of smaller sphere.

The statement that best describes the chord of a circle is a chord is any segment in which the end points are found on the arc of the circle. (option a).

A chord of a circle is a line segment that connects two points on the circle. The two endpoints of the chord are called the endpoints of the chord, and they lie on the circumference of the circle.

Therefore, option (a) that states that a chord is any segment in which the endpoints are found on the arc of the circle is the correct answer.

It is important to note that a chord does not have to pass through the center of the circle. If a chord passes through the center of the circle, it is called a diameter. A diameter is the longest chord of a circle, and it divides the circle into two equal parts called semicircles.

The correct answer to the question is option (a), which states that a chord is any segment in which the endpoints are found on the arc of the circle.

Step-by-step explanation:

\(6(3p-2)=20\)

Distribute the brackets.

\(6(3p)+6(-2)=20\)

\(18p-12=20\)

Add \(12\) on both sides.

\(18p-12+12=20+12\)

\(18p=20+12\)

\(18p=32\)

Divide \(18\) on both sides.

\(\frac{18p}{18}=\frac{32}{18}\)

If a bank receives a new deposit of $15,000, the bank can lend out $13,785.

The required reserve ratio is the fraction of deposits that banks must hold as reserves. If the current required reserve ratio is 8.1% and a bank receives a new deposit of $15,000, they can lend out $13,785.

The bank can lend out the amount equal to the deposit minus the required reserve amount. In this case, the new deposit is $15,000 and the required reserve ratio is 8.1%, so the calculation is as follows:

Required reserve amount = Deposit × Required reserve ratio

Required reserve amount = $15,000 × 0.081

Required reserve amount = $1,215

The bank must hold $1,215 as required reserves and can lend out the remaining amount:Amount available for lending = Deposit − Required reserve amount

Amount available for lending = $15,000 − $1,215

Amount available for lending = $13,785
