The probability of flipping a heads on the coin and rolling a 5 on the die is 1/12 if a coin is flipped and die is rolled once.

The sample space for the coin toss is  {H,T}, so there are two possible outcomes. The favorable one is  H.

The probability of flipping a heads on the coin is equal to 1/2.

Die has six faces, meaning six possible outcomes, but we’re only interested in one of those outcomes: that roll of a 5. That means that only 1 in 6 outcomes is desirable and we can write it as  1/6

The probability of rolling a 5 on the die is equal to 1/6.

Since a coin is flipped and die is rolled independently, the joint probability is a product of above probabilities.

Therefore, the probability of flipping a heads on the coin and rolling a 5 on the die equals

[tex]\frac{1}{2} \times \frac{1}{6}\\= \frac{1}{12}[/tex]

The correct option for a parabola with given details is D i.e. A curve declines through (negative 1, 6), (0, 4), (1, 2), (2, 1), (4, 0) and (6, 1) on the x y coordinate plane.

What exactly is a parabola?

A parabola is a U-shaped plane curve in which any point is an equal distance from both a fixed point (known as the focus) and a fixed straight line (known as the directrix).

In general, if the directrix is parallel to the y-axis, the typical parabola equation is: y² = 4ax.

If the parabola is sideways, i.e., the directrix is parallel to the x-axis, the conventional parabola equation is x² = 4ay.

Aside from these two, if the parabola is in the negative quadrants, the equation can also be y²= -4ax and x² = -4ay.

Now,

The Graph is drawn for option D in the image and it matches the

details provided in the question.

Hence,

           The correct option for a parabola with given details is A curve declines through (negative 1, 6), (0, 4), (1, 2), (2, 1), (4, 0) and (6, 1) on the x y coordinate plane.

Step-by-step explanation:

Think the people as points in space and the friendship between two people as a line connecting two points.

Then the question is equivalent to asking whether it is possible for all 11 points being connected by lines such that every point is connected to exactly three other points.

Clearly this is possible, since we always have, for each point, ten other points to connect it to, so we can select any three of the ten.

The linear function modeled by the table is given as follows:

y = 2x - 5.

The slope and the intercept are given, respectively, by:

m = 2, b = -5.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

From the table, when x increases by 5, y increases by 10, hence the slope m is given as follows:

m = 10/5

m = 2.

Hence:

y = 2x + b.

When x = 3, y = 1, hence the intercept b is given as follows:

1 = 6 + b

b = -5.

The value of x by using vertical angles is 4, and the measure of angle R is 34°

Vertical angles are angles that are formed and are opposite of each other when two lines intersect. Vertical angles are congruent angles, it implies that they exhibit the same angle measure. Vertical here refers to the fact that they have the same Vertex (corner point).

From the information given:

6x + 10 = 8x + 2

6x - 8x = 2 - 10

-2x = -8

x = -8/-2

x = 4

The measure of angle R = 6x + 10

= 6(4) + 10

= 24 + 10

since we get that  PA = OP = c

therefore when we compare RS and PQ ,we get,

For a diamond having volume 161 mm³, the value for side length is 7 mm.

What is volume?

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

The formula for volume of diamond is given as -

V = 0.47 s³

Here, s represents the side length of each edge.

The value for volume of diamond is given as -

Volume = 161 mm³

Plug in the values in the equation -

Volume = 0.47 s³

161 = 0.47 s³

s³ = 161 / 0.47

s³ = 342.553

s = ∛342.553

s = ∛342.553

s = 6.996 mm

The probability of obtaining a random sample of 75 units from a production process where the true fraction of nonconforming product is 0.01 is extremely high. This is because 0.01 is an extremely low fraction, meaning that out of the 75 units in the sample, only 0.75 would be expected to be nonconforming.

The probability that the fraction of nonconforming product is exactly 0.01 (with 0.75 nonconforming units out of 75) can be calculated using the binomial distribution. This distribution assumes that each unit has an independent probability of being nonconforming, and that this probability is the same for each unit. The probability that the sample will have exactly 0.75 nonconforming units out of 75 is 0.907.

Thus, the probability that the true fraction of nonconforming product is exactly 0.01 is very high, and it is likely that a random sample of 75 units drawn from the production process will have a fraction nonconforming that is close to 0.01.

The original number of roommates was 6, determined by comparing the original and new shares of rent per roommate and solving for the minimum number of roommates that satisfies the inequality.

Let's assume that there were 'x' original roommates in the apartment.

When the rent was shared equally among 'x' roommates, each roommate's share was:

[tex]6000/x[/tex]

After four roommates moved out, the remaining roommates continued to share the same rent of $6000 but each person's share increased by $250. So the new share per roommate is:

[tex](6000/x) + 250[/tex]

Since the number of roommates decreased by 4, the new number of roommates is:

[tex]x - 4[/tex]

We know that the new share per roommate is greater than the original share per roommate, so we can set up the following inequality:

[tex](6000/x) + 250 > 6000/x[/tex]

Simplifying the inequality, we get:

[tex]250 > 6000/x - 6000/x[/tex]

[tex]250 > 6000/x^2[/tex]

[tex]x^2 > 24[/tex]

[tex]x > 4.9[/tex]

Since the number of roommates must be a whole number, the minimum value for x is 6.

Therefore, there were originally 6 roommates in the apartment.

The solution involves setting up an inequality to compare the original share of the rent per roommate with the new share of the rent per roommate, and then solving for the minimum number of original roommates that satisfies the inequality.

The size of angle BCA is 45 degrees

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

AB = BC and AD = DC = AC

Also, we have

ABC = 90 degrees

Considering the triangle ABC, we have

A + B + C = 180

This is so because the sum of angles in a triangle is 180 degrees

Using the above as a guide, we have the following:

A + 90 + C = 180

So, we have

A + C = 90

Given that

AB = BC
