Juaquin has $57 to purchase cell phone accessories. he buys c number of cases and a charger. write an inequality that can be used to find the number of cases that juaquin can purchase.

Answer:

3

Step-by-step explanation:

We can use the formula of slope to find this answer.

The formula to find the slope is y2-y1/x2-x1.

The slope of line ST is 1/5: 2-0/5-(-5);   2/10=1/5

We know that for two lines to be perpendicular, they have to have reciprocal opposite slopes. For example, if the slope of a line is 2/1 then the slope of a line perpendicular is -1/2.

Therefore, the perpendicular line should have a slope of: 1/5------>-5

To find which answer it is, follow the steps below:

y2-y1/x2-x1

plugin known values

-2-y1/0-(-1)

-2-y1/1

In order to make this -5, y1 needs to be 3

-2-3/1=-5

3 is the correct value

The value of y is 3.

The slope of a line is a measure of its steepness.

Given:

Ware( -1, y)

Now,

slope of line ST =2-0/5-(-5)

slope=1/5

As two lines to be perpendicular, they have to have reciprocal opposite slopes.

Thus, the perpendicular line slope =-5

Now, y2-y1/x2-x1

= -2-y1/0-(-1)

= -2-y1/1

= -2-3/1

=-5

hence, the value of y is 3.

The probability that at least two of them will score the Mathematics question right is 28/75.To calculate the probability that at least two of them will score the Mathematics question right, we need to consider all possible combinations in which two or more individuals can score it right.

Probabilities individually:

- Victor has a probability of 1/5 (or 0.2) to score it right.

- Noah has a probability of 2/3 (or approximately 0.67) to score it right.

- Timothy has a probability of 2/5 (or 0.4) to score it right.

The probability that at least two of them will score it right, we need to consider three cases:

1. All three of them score it right: This occurs with a probability of (1/5) * (2/3) * (2/5) = 4/75.

2. Two of them score it right: There are three possible combinations where two individuals can score it right: Victor and Noah, Victor and Timothy, and Noah and Timothy. The probability for each combination is:

  - Victor and Noah: (1/5) * (2/3) * (3/5) = 6/75.

  - Victor and Timothy: (1/5) * (1/3) * (2/5) = 2/75.

  - Noah and Timothy: (4/5) * (2/3) * (2/5) = 16/75.

  The total probability for this case is (6/75) + (2/75) + (16/75) = 24/75.

3. Only one or none of them score it right: This occurs with a probability of 1 - [(4/75) + (24/75)] = 47/75.

Therefore, the probability that at least two of them will score the Mathematics question right is (4/75) + (24/75) = 28/75.

In summary, the probability that at least two of them (Victor, Noah, and Timothy) will score the Mathematics question right is 28/75. This is obtained by calculating the probabilities of all possible combinations where two or more individuals score it right, and then summing up those probabilities.

Answer:

The hypotenuse is 55 miles

Step-by-step explanation:

Given the sides of a right angle triangle as 33 and 44 miles, we want to get the hypotenuse

Mathematically, by Pythagoras’ theorem, the hypotenuse square is the sum of the squares of the other two sides

So we have;

h^2 = 33^2 + 44^2

h^2 = 3025

h = √3025

h =55 miles

The correct answer is not provided in the given options. The sun would not be visible at noon on December 21 in a city at 60°N latitude.

The angle of the sun above the horizon at noon on December 21 depends on the latitude of your city. Since you mentioned that you live at 60°N, we can determine the angle using some knowledge about the tilt of the Earth and the seasons.

On December 21, the winter solstice, the Northern Hemisphere is tilted away from the sun. This means that the angle of the sun above the horizon at noon is lower than on other days of the year.

To calculate the angle, we need to subtract the latitude of your city (60°N) from the tilt of the Earth (23.5°).

So, the angle of the sun above the horizon at noon on December 21 in your city would be:
23.5° - 60° = -36.5°

The negative sign indicates that the sun is below the horizon at noon on December 21. Therefore, the correct answer is not provided in the given options. The sun would not be visible at noon on December 21 in a city at 60°N latitude.

The number of sets is 128 by using the multiplication principle.

The multiplication principle states that if there are k events, and if the first event can happen in n_1 ways, the second event can happen in n_2 ways, and so on, then the k events can happen in n_1 × n_2 × ... × n_k ways.

To find the number of sets of four marbles include one of each color other than lavender, A bag contains two red marbles, four green ones, one lavender one, four yellows, and four orange marbles.

There are two red marbles.

There are four green ones.

There are four yellows.

There are four orange marbles.

So, total of 2 + 4 + 1 + 4 + 4 = 15 marbles in the bag.

To find the total number of sets of four marbles including one of each color other than lavender, use the multiplication principle.

In this question, there are 5 events (choosing one of each color).

The first event can happen in 2 ways.

The second event can happen in 4 ways.

The third event can happen in 4 ways.

The fourth event can happen in 4 ways.

The events where the occurrence of one event does not affect the probability that the other event will occur are independent events.

In probability theory, two events are said to be independent if the occurrence of one event does not affect the probability of the occurrence of the other event. In other words, the probability of one event occurring does not depend on whether or not the other event has occurred.

For example, if we toss a fair coin twice, the outcome of the first toss does not affect the probability of the second toss. The probability of getting heads on the second toss is still 1/2, regardless of whether the first toss was heads or tails. Therefore, the two coin tosses are independent events.

Similarly, if we roll a fair six-sided die twice, the outcome of the first roll does not affect the probability of the second roll. The probability of getting a particular number on the second roll is still 1/6, regardless of whether the first roll was that number or not.

Independent events are important in probability theory because they allow us to use multiplication rules and conditional probability to calculate the probability of complex events.

From the given information, we know that V, W, and X are points on a circle with center V, and that VW = WX = 3. We also know that ∠WVX = 90°.

Since WX is a diameter of the circle, it has length equal to twice the radius of the circle. Let r be the radius of the circle, then we have:

VW + WX = 2r

3 + 3 = 2r

r = 3

When cattle with the red coat allele (r) and white coat allele (r') are crossed, the resulting offspring will have a roan coat color, representing an example of incomplete dominance.

In cattle, the allele for red coat color (r) exhibits incomplete dominance over the allele for white coat color (r'). In incomplete dominance, the heterozygous condition (rr') results in an intermediate phenotype that is different from both homozygous conditions.

When a red-coated individual (rr) is crossed with a white-coated individual (r'r'), the resulting offspring will have the genotype rr'. In terms of coat color, the offspring will exhibit a roan coat color, which is a mixture of red and white hairs. This is because neither the red allele (r) nor the white allele (r') is completely dominant over the other. Instead, they interact and blend to produce the roan phenotype.

In roan cattle, the red and white hairs are evenly interspersed, creating a mottled or speckled appearance. The extent of the roan phenotype may vary among individuals, with some displaying a more balanced mixture of red and white, while others may have a more dominant color.

It's important to note that incomplete dominance is different from complete dominance, where one allele completely masks the expression of the other. In the case of incomplete dominance, the heterozygous genotype results in an intermediate phenotype, showcasing a blending of traits.

In conclusion, the progeny of calves having the red coat gene (r) and white coat allele (r') will have a roan coat colour, illustrating an instance of incomplete dominance.

The value of b that makes b + c minimum is -2.  The product of the roots of a quadratic equation of the form ax^2 + bx + c = 0 is given by c/a.

Therefore, for the equation x^2 - bx + c = 0, the product of the roots p and q is simply c.

To maximize the product pq, we need to maximize c. Since c is the product of the roots p and q, it will be maximum when p and q are equal. Let p = q = r.

Thus, the equation becomes x^2 - 2rx + r^2 = 0.

Using the quadratic formula, we get:

x = r ± sqrt(r^2 - r^2) = r ± 0

Therefore, the roots of the equation are p = q = r.

Using Vieta's formulas, we have:

p + q = 2r = b

pq = r^2 = c

We need to find the value of b that makes b + c minimum. Substituting b = 2r into the expression, we get:

b + c = 2r + r^2

To minimize this expression, we can take the derivative with respect to r and set it equal to zero:

d/d r (2r + r^2) = 2 + 2r = 0

Solving for r, we get:

r = -1

Substituting r = -1 back into the equations for b and c, we get:

b = 2r = -2

c = r^2 = 1
