Answer:

ΑΠSШЕЯ®

Step-by-step explanation:

The probability that all three students prefer to take some of their courses fully online can be found by multiplying the probabilities of each event together. Since each student has a 68% chance of preferring fully online courses, the probability that the first student prefers fully online courses is 0.68, the probability that the second student prefers fully online courses given that the first student does is also 0.68, and the probability that the third student prefers fully online courses given that the first two students do is also 0.68. Therefore, the probability that all three students prefer to take some of their courses fully online is 0.68 x 0.68 x 0.68 = 0.314. The probability is approximately 0.314 or 31.4%.

Answer:

B. Triangle A and B

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The line in option D, y = 3x, does not intersect with any of the other lines.

To see this, we can first note that options A and B have slopes of -3 and 3, respectively, which means they are parallel lines. Therefore, they will never intersect.

Option C has a slope of 3 as well, but its y-intercept is -7, which is different from the y-intercept of line B, which is 7. This means that these two lines are not parallel and will intersect at some point.

On the other hand, line D has a slope of 3 and a y-intercept of 0 (since there is no constant term), which means it passes through the origin. Therefore, it will not intersect with any of the other lines unless one of the other lines also passes through the origin, which is not the case here.

Therefore, the line that does not intersect with any of the other lines is option D, y = 3x.

Answer:  B. y = 3x + 7 and y = -3x + 7 are parallel lines, so they do not intersect.

Step-by-step explanation:

Two lines in a plane may intersect at a point, be parallel, or be coincident (overlapping). To determine which of the given lines do not intersect, we need to find the slope of each line and check for parallelism.

The slope-intercept form of a line is given by y = mx + b, where m is the slope and b is the y-intercept. Therefore, we can write the equations of the given lines in slope-intercept form as follows:

A. y = -3x - 7 (slope m = -3)

B. y = 3x + 7 (slope m = 3)

C. y = 3x - 7 (slope m = 3)

D. y = 3x (slope m = 3)

From the slopes, we can see that lines B and C have the same slope of 3, so they are parallel. Therefore, they do not intersect at any point in the plane. Lines A and D have different slopes, so they are not parallel and will intersect at some point in the plane.

The probability of both getting a heart card and a red heart card is 1/4.

Given that there is a deck of 52-cards, we need to find the probability of getting a heart cards,

Probability shows how likely an event will happen.

P(E) = n(E) /n(S).

n(E) = Number of favorable outcomes of E.

n(S) = total number of possible outcomes of E.

No. of heart cards = 13

n(E) = 13

P (getting a card of heart) = no. of favorable outcomes/total no. of possible outcomes of E

= 13/52

= 1/4

Since heart card is red that means there are 13 heart cards which is red in color.

So, the probability of getting a red heart card = 13/52 = 1/4

Hence the probability of both getting a heart card and a red heart card is 1/4.

The fixed cost is $275, and the variable cost for each product is $0.25.

The cost function can be written as: C(x) = 275 + 0.25x

(a) The linear cost function representing the cost C(x) (in $) to the vendor to produce x products can be determined by considering both the fixed cost (booth setup) and the variable cost (cost per product).

The fixed cost is $275, and the variable cost for each product is $0.25.

Therefore, the cost function can be written as:

C(x) = 275 + 0.25x

b. (b) R(x) = 3x, where x is the number of products sold and R(x) is the revenue in dollars.

(c) To break even, the cost must equal the revenue: 0.25x + 275 = 3x. Solving for x, we get x = 137.5. The vendor must produce and sell 138 products to break even.

(d) If 40 products are sold, the cost is C(40) = 0.25(40) + 275 = $285, and revenue is R(40) = 3(40) = $120. The vendor will lose money, as the cost is greater than the revenue.

The volume inside the cube but outside of an inscribed sphere is 231.6 cubic inches

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

This means that the side length of the cube is

l³ = 486

So, we have

l = 7.86

This represents the diameter of the sphere

So, the sphere volume is

V = 4/3πr³

So, we have

V = 4/3 * 22/7 * (7.86/2)³

Evaluate

V = 254.36

So, the required volume is

Volume = 486 - 254.36

The sample space for choosing 2 marbles from the bag with replacement

Purple Red Blue

Purple Purple, Purple Purple, Red Red, Blue

(option c)

To find the sample space, we need to list all possible outcomes. Since we are choosing two marbles, we can have three possible outcomes for the first marble: purple, red, or blue. Similarly, we can also have three possible outcomes for the second marble.

To construct the sample space, we need to list all possible pairs of the first and second marbles. Since we are choosing two marbles, the total number of pairs will be the product of the number of outcomes for each marble. In this case, we have three outcomes for each marble, so the total number of pairs will be:

3 x 3 = 9

Therefore, there are nine possible pairs of marbles that we can select from the bag with replacement. To represent the sample space in a table, we can list all possible pairs of marbles as follows:

The factored form of the expression 816² - 25c² is 816 + 5c )( 816 - 5c).

Given the expression in the question:

816² - 25c²

To factor 816² - 25c², we the:

Answer: y=2+6

Step-by-step explanation:

Answer:

The conic section basis of the equation x^2 + xy + y^2 + 2x = -3 can be determined by examining the coefficients of the x^2, xy, and y^2 terms.

To do this, we can start by completing the square for the quadratic terms in the equation:

x^2 + xy + y^2 + 2x = -3

(x^2 + 2x) + xy + y^2 = -3

(x + 1)^2 - 1 + xy + y^2 = -3

(x + 1)^2 + xy + y^2 = -2

Now, we can see that the coefficient of the xy term is positive, which indicates that the conic section is an ellipse. Specifically, this is a rotated ellipse because the x and y terms are not squared separately and have a non-zero coefficient.

Therefore, the conic section basis of the equation x^2 + xy + y^2 + 2x = -3 is a rotated ellipse.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The given equation is:

x^2 + xy + y^2 + 2x = -3

To identify the conic basic of the equation, we need to check its discriminant, which is given by:

Δ = B^2 - 4AC

where A, B, and C are the coefficients of x^2, xy, and y^2 terms respectively.

In this case, A = 1, B = 1, and C = 1.

So,

Δ = B^2 - 4AC

= 1^2 - 4(1)(1)

= -3

Since the discriminant is negative, the given equation represents an ellipse.

The slope which shows  the cost per guest is $35 per guest

The given cost for 50 guests is $2150.

The cost for 75 guests is $3025.

It can also be represented as:

(Guest, Cost) =(50, $2150) & (75, $3025)

The slope can now be calculated as

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (50, $2150) & (75, $3025)

Substituting the given values in the equation as follows:

Slope = (3025 - 2150)/(75 - 50)

Answer: x = -2.

Step-by-step explanation:

-8x + 44 ≥ 60

Subtracting 44 from both sides, we get:

-8x ≥ 16

Dividing both sides by -8 (and reversing the inequality since we are dividing by a negative number), we get:

x ≤ -2

Next:

-4x + 50 < 58

Subtracting 50 from both sides, we get:

-4x < 8

Dividing both sides by -4 (and reversing the inequality), we get:

x > -2

Putting the two inequalities together, we get:

-2 < x ≤ -2

This means that the solution for x is x = -2.
