Brei owes her mom $19.80 for the phone call.

To calculate how much Brei owes her mom for the phone call, let's break down the call into two time periods: before 8:00 a.m. and after 8:00 a.m.

Before 8:00 a.m.:

The call started at 7:00 a.m. and ended at 8:00 a.m., making it a duration of 1 hour (60 minutes).

The cost for the first minute is $0.35, and for the subsequent minutes, it's $0.20 per minute. So for the remaining 59 minutes, the cost is:

59 minutes * $0.20/minute = $11.80

The total cost for the call before 8:00 a.m. is:

$0.35 (first minute) + $11.80 (remaining minutes) = $12.15

After 8:00 a.m.:

The call continued from 8:00 a.m. to 8:30 a.m., which is a duration of 30 minutes.

The cost for the first minute is $0.40, and for the subsequent minutes, it's $0.25 per minute. So for the remaining 29 minutes, the cost is:

29 minutes * $0.25/minute = $7.25

The total cost for the call after 8:00 a.m. is:

$0.40 (first minute) + $7.25 (remaining minutes) = $7.65

To find the total cost for the entire call, we sum up the costs from both time periods:

$12.15 (before 8:00 a.m.) + $7.65 (after 8:00 a.m.) = $19.80

Answer:

Step-by-step explanation:

The higher-cost item is forks, so we can let x represent the number of those that are purchased. The total number purchased is 7, so the number of spoons purchased is (7-x).

The total cost is the sum of the costs for each of the items:

  6x +5(7-x) = 40

  x +35 = 40 . . . . . . simplify

  x = 5 . . . . . . . . . . . subtract 35; the number of forks

  7-x = 2 . . . . . . . . . the number of spoons

Daniel bought 5 forks and 2 spoons.

_____

Additional comment

Since $40 is not divisible by $6, we can guess that the number of forks Daniel bought will be a multiple of 5. That is, Daniel bought 0 or 5 forks. If he bought 0 forks, then he must have bought 40/5 = 8 spoons, so that is not a viable choice. The only number of forks that makes sense in this problem is 5 forks, so 2 spoons--numbers that total 7, as required.

Step-by-step explanation:

The slope of the equation is -2/3, and the y-intercept is 490.

To change the equation 2x + 3y = 1,470 to slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept, we need to solve for y.

Starting with the given equation:

2x + 3y = 1,470

First, let's isolate y by subtracting 2x from both sides of the equation:

3y = -2x + 1,470

Next, divide both sides of the equation by 3 to solve for y:

y = (-2/3)x + 490

Now we have the equation in slope-intercept form, y = (-2/3)x + 490.

From this form, we can identify the slope and y-intercept:

The slope (m) is the coefficient of x, which is -2/3.

The y-intercept (b) is the constant term, which is 490.

Therefore, the slope of the equation is -2/3, and the y-intercept is 490.

The area of the triangle is 4.5 square unit.

We have, y= 4x/ (1 + x³)

Now, differentiating the above equation wrt to x we get

y' = 4(1 + x³)- 4x . 3x² / (1+ x³)²

y'= -8x³ + 4/ (1+x³)²

When x = 1 then y' = -4/4 = -1

so, y -2 = -1 (x-1)

y= -x+ 3

Here the x intercept is (3, 0) and y intercept is (0, 3).

The probability of selecting a diamond or 9 is 1/13.

Step by step explanation: There are 4 suits (diamonds, clubs, hearts, and spades) and 13 ranks (2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, and Ace). The probability of selecting a card from a standard deck of 52 cards is 1/52.

To calculate the probability of selecting a diamond or a 9, you must first calculate the total number of diamonds and nines in the deck, which is 8 (4 diamonds and 4 nines). The probability of selecting a diamond or 9 is 8/52, which reduces to 1/13.

A important goal of inferential statistical analysis is to generalize results from the study to the target population (option c).

An important goal of inferential statistical analysis is to generalize the findings and results obtained from a study or sample to the larger target population. Inferential statistics involves making inferences, drawing conclusions, and making predictions about a population based on the analysis of a sample.

When conducting a study, it is often impractical or impossible to collect data from the entire population of interest. Instead, a sample is typically selected and studied. Inferential statistics helps researchers make inferences about the population based on the sample data.

By analyzing the sample data using inferential statistical techniques, researchers can estimate population parameters, test hypotheses, determine the significance of findings, and make predictions about the larger population. This allows for generalization of the findings and helps in making informed decisions and drawing conclusions that extend beyond the specific sample studied.

Options A, B, and D are also important goals in statistical analysis, but they are not specific to inferential statistics. Analyzing and describing data (option A) is a goal of descriptive statistics. Determining the validity of theoretical constructs (option B) and measuring the reliability and validity of measurement tools (option D) are goals related to assessing the quality and soundness of research instruments and constructs, but they do not specifically address the goal of generalizing results to a larger population. The correct option is c.

The complete question is:

We need to find the function f(n) whose terms are the same as the series in question. We can then integrate this function from n=1 to infinity and determine if the integral is convergent or divergent. If it is convergent, then the series is convergent. If it is divergent, then the series is also divergent.

To determine whether a series is convergent or divergent using the integral test, we need to first check if the series satisfies three conditions:

1) The terms of the series are positive.

2) The terms of the series are decreasing.

3) The series has an infinite number of terms.

Assuming these conditions are satisfied, we can use the integral test which states that if the integral of the function f(x) from n=1 to infinity is convergent, then the series with terms a_n = f(n) is also convergent. Conversely, if the integral is divergent, then the series is also divergent.

2x+3y= 6          <====  Multiply entire equation by 2 to get :

Using the inner product,

(a) {p, q} is -6

(b) ||p|| is √t{30}.

(c) ||q|| is √{2}.

(d) d(p, q) is √{38x^4 - 56x^3 + 22x^2 - 6x + 30}.

(a) To find {p, q}, we need to compute the inner product of the two polynomials:

{p, q} = a0b0 + a1b1 + a2b2

= (2)(0) + (-1)(1) + (5)(-1)

= -6

Therefore, {p, q} = -6.

(b) To find ||p||, we first need to find p , which is the norm of p. Using the formula p(x) = √{<p, p>} = √{a0^2 + a1^2 + a2^2}, we get:

p(x) = sqrt{<p, p>} = √{2^2 + (-1)^2 + 5^2}

= √{30}

Therefore, ||p|| = √{30}.

(c) Similarly, we can find ||q|| by finding q , which is the norm of q. Using the formula q(x) = √{<q, q>} = √{b0^2 + b1^2 + b2^2}, we get:

q(x) = √{<q, q>} = √{0^2 + 1^2 + (-1)^2}

= √{2}

Therefore, ||q|| = √{2}.

(d) Finally, to find the distance d(p, q) between p and q, we can use the formula:

d(p, q) = ||p - q|| = √{<p-q, p-q>}

First, we need to find p - q:

p - q = (2 - x + 5x^2) - (x - x^2)

= 2 - 2x + 6x^2

Now, we can compute d(p, q):

d(p, q) = ||p - q|| = √{<p-q, p-q>}

= √{(2-2x+6x^2)^2 + (-x+x^2)^2 + 5^2}

= √{38x^4 - 56x^3 + 22x^2 - 6x + 30}

Therefore, d(p, q) = √{38x^4 - 56x^3 + 22x^2 - 6x + 30}.

Answer:

16 inches

Step-by-step explanation:

12 divided by 3 is 4

4 inches for 1/4 of the year

4 x 4 = 16 inches

The maximum Number of  scholars in each row is 12. This means that the  scholars can be arranged in rows with an equal number of  scholars, and each row can have a  outside of 12  scholars.

To find the maximum number of  scholars in each row, we need to determine the  topmost common divisor( GCD) of the total number of  scholars in each section. The GCD represents the largest number that divides all the given  figures unevenly.  

Given that there are 24, 36, and 60  scholars in the three sections, we can calculate the GCD as follows    Step 1 List the  high factors of each number  24 =  23 * 31  36 =  22 * 32  60 =  22 * 31 * 51    

Step 2 Identify the common  high factors among the three  figures  Common  high factors 22 * 31    Step 3 Multiply the common  high factors to find the GCD  GCD =  22 * 31 =  4 * 3 =  12  

 thus, the maximum number of  scholars in each row is 12. This means that the  scholars can be arranged in rows with an equal number of  scholars, and each row can have a  outside of 12  scholars.
