The average speed in miles per hour during her drive that morning is 43.5 miles per hour   .

In the question ,

it is given that ,

the distance between home to freeway entrance is = 0.6 miles

the distance between freeway entrance to freeway exit is = 15.4 miles

the distance between freeway exit to workplace is = 1.4 miles

So , the distance from home to work place = 0.6 + 15.4 + 1.4 = 17.4 miles

we know that 24 minutes = 24/60 = 0.4 hours ,

the average speed = total  distance / total time

= 17.4/0.4

= 43.5 miles per hour

Therefore , the average speed is 43.5 miles per hour .

Step-by-step explanation: divide 3494 by 8

There will be 6 comics left over after putting them in groups of 8

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Bertie has 3494 comic books he wants them in groups of 8.

∴ The no. of groups can be obtained if we divide the total number of books by no. of books in each group which is,

= (3494/8).

= 438×8 + 6.

Answer:

the sequence is geometric sequence with common ratio (-2).

Option : D is correct.

Step-by-step explanation:

In this question table is given as

n          1          2         3           4            5

f(n)     48       -96      192      -385       768

We have to find out if the sequence is arithmetic or geometric.

For Arithmetic sequence :

Difference should be common in each term of fees.

common difference  = f(2) - f(1)

= -96 -48 = -144

similarly  = f(3) - f (2) = 192 + 96 = 288

Here,  ≠  so the sequence is not an arithmetic sequence.

For Geometric sequence :

Ratio  should be common in each term of f(n)

Common ratio  =

Therefore, the sequence is geometric sequence with common ratio (-2).

The correct answer of estimation for each expression is 269,900, 220,251.7, 240,220.1 and 250,268.1.

270,349.6 - 112.8 = 270,236.8

To estimate, we can round 270,349.6 to 270,000 and round 112.8 to 100. Subtracting 100 from 270,000 gives us 269,900. Therefore, the estimated answer is 269,900.

220,173.3 + 78.4 = 220,251.7

To estimate, we can round 220,173.3 to 220,000 and round 78.4 to 80. Adding 80 to 220,000 gives us 220,080. Therefore, the estimated answer is 220,080.

240,817.2 - 597.1 = 240,220.1

To estimate, we can round 240,817.2 to 240,000 and round 597.1 to 600. Subtracting 600 from 240,000 gives us 239,400. Therefore, the estimated answer is 239,400.

250,108.8 + 159.3 = 250,268.1

To estimate, we can round 250,108.8 to 250,000 and round 159.3 to 160. Adding 160 to 250,000 gives us 250,160. Therefore, the estimated answer is 250,160.

Letting x = 2 and y = 5, we can compute the value of the expression. The value of the expression x - y / (y * x^3) with x = 2 and y = 5 is 1.875.

In MATLAB, we can assign values to variables and perform arithmetic operations to compute the desired expression. To evaluate the expression x - y / (y * x^3) with x = 2 and y = 5, we can use the following MATLAB commands:

```

x = 2;

y = 5;

result = \(x - y / (y * x^3)\)

```

After executing these commands, the variable `result` will contain the computed value of the expression.

In this case, with x = 2 and y = 5, the expression evaluates to:

```

result = 2 - 5 / (5 * 2^3)

      = 2 - 5 / (5 * 8)

      = 2 - 5 / 40

The area of a circle with radius 4 is 50.24.

Writing the equation form for area and radius of two circles -

(Area/radius²) for circle 1 = (Area/radius²) for circle 2

Keep the values in the relation to find the area of small circle.

314/10² = Area/4²

Area = (314 × 16)/100

Performing multiplication on Right Hand Side of the equation to find the area of circle

Area = 5024/100

Performing division on Right Hand Side of the equation to find the area of circle

Area = 50.24

Hence, we see the decrease in area based on decrease in radius. Thus, the area of circle is 50.24.

Note that based on probabilities,

The expected number of Democrats on the committee is 5.

The expected number of states represented on the committee is 26.

The expected number of states such that both of the state's senators are on the committee is 9.09.

a)  The probability that a randomly chosen senator is a Democrat is 50/100 = 1/2.

So, the expected number of Democrats on a committee of size 10 is

1/2 * 10 = 5.

b) The minimum number of   states that can be represented on a committee of size 10 is 2, and the maximum numberis 50.

The expected number of states representedon the committee is the average of these two values, which is (2 + 50)/  2 = 26.

c)  There are 50 states, and each state has 2 senators. So, there are a total of 100 pairs of senators.

The probability that a randomly chosen pair of senators both belong to the same state is 50/100 * 49/99

The combined probability is: p × (1 - p)²⁸,  (1 - p) represents the probability that a user is not transmitting, and (1 - p)²⁸ represents the probability that the remaining 28 users are not transmitting.

To calculate the probability that one user is transmitting while the remaining users are not transmitting, we need to make some assumptions and define the conditions of the system.

Assumptions:

1. Each user's transmission is independent of the others.

2. The probability of each user transmitting is the same.

Let's denote the probability of a user transmitting as "p". Since there are 29 users, the probability of one user transmitting and the remaining 28 users not transmitting can be calculated as follows:

Probability of one user transmitting: p

Probability of the remaining 28 users not transmitting: (1 - p)²⁸

To find the combined probability, we multiply these two probabilities together:

Probability = p × (1 - p)²⁸

Please note that without specific information about the value of "p," it is not possible to provide an exact numerical value for the probability. The value of "p" depends on factors such as the traffic patterns, the behavior of users, and the system design.

Step-by-step explanation:

The absolute minimum of the function on the domain [-3, 0] is (-√3, -√3)

From the question, we have the following parameters that can be used in our computation:

\(f(x) = \frac{6x}{x^2 + 3}\)

Differentiate the function

So, we have

\(f'(x) = -\frac{6(x^2 - 3)}{(x^2 + 3)^2}\)

Set the differentiated function to 0

So, we have

\(-\frac{6(x^2 - 3)}{(x^2 + 3)^2} = 0\)

This gives

-6(x² - 3) = 0

Divide by -6

x² - 3 = 0

When solved for x, we have

x = ±√3

The domain is [-3, 0]

So, we have

x = -√3

Recall that

\(f(x) = \frac{6x}{x^2 + 3}\)

This gives

\(f(-\sqrt3) = -\frac{6\sqrt3}{3 + 3}\)

\(f(-\sqrt3) = -\frac{6\sqrt3}{6}\)

Evaluate

f(-√3) = -√3

Hence, the absolute minimum is (-√3, -√3)
