Answer:

Step-by-step explanation:

The question pertains to multiplying a percentage by a large population to predict the number of incidences. In this case, 0.1% of 5,200,000 is 5,200, meaning we would expect about 5,200 people to exhibit side effects.

The question asks about the expected number of people likely to exhibit side effects from a chemical compound, given a known rate of incidence. From the data provided, 0.1% of participants in trials showed side effects. If you want to extrapolate this rate to a larger population of 5,200,000 people, you would multiply the population by the side effect rate in decimal form (0.1% = 0.001).

Here's the step-by-step calculation:

Therefore, if the same rate of side effects continues, you would expect about 5,200 people in a population of 5,200,000 to exhibit similar side effects.

Therefore, the Knicks travel two times further when they play the Lakers compared to the Miami Heat.

Time is a fundamental concept used to describe the sequence of events and the duration between them. It is a continuous and irreversible flow of moments and intervals in which events occur in a chronological order. Time can be measured by various units, such as seconds, minutes, hours, days, weeks, months, and years, and is commonly divided into past, present, and future. Time is often perceived subjectively, with its perception varying depending on factors such as an individual's location, culture, and personal experience. The study of time is an essential part of various fields, including physics, philosophy, psychology, and sociology.

To find out how many times further the Knicks travel when they play the Lakers compared to the Miami Heat, we need to divide the larger distance (the distance between Madison Square Garden and the Staples Center) by the smaller distance (the distance between Madison Square Garden and the American Airlines Arena).

Answer:

Let's use the equation:

Total earnings = Base pay + Commission

Xavier's base pay is $150 per day, and his commission is x percent of his daily sales, which is $1250 in this case. Therefore, we can write the equation as:

$200 = $150 + (x/100) * $1250

Simplifying the equation:

$200 - $150 = (x/100) * $1250

$50 = (x/100) * $1250

Dividing both sides by 1250:

0.04 = x/100

Multiplying both sides by 100:

x = 4

Therefore, the commission percentage for Xavier on that day was 4%.

A. An equivalent expression to represent the sale price of the item of p - 0.1p = 0.9p.

B. The different ways to be used to find the sale price of an item in Midland Electronics are:

(i) We can take the original price of the item and multiply it by 0.9, which is the percentage of the original price that is being paid after the 10% discount.

(ii) Or we can subtract the discount amount from the original price, where the discount amount is equal to 0.1 times the original price.

Both of these methods lead to the same sale price of the item.

We can write the expression by:

Simplify the expression p - 0.1p by factoring out the common factor of p:

p - 0.1p = p(1 - 0.1)

Simplifying further, we can see that 1 - 0.1 equals 0.9

Substitute the value back into the expression:

p - 0.1p = p(1 - 0.1)

= p(0.9) = 0.9p

Thus, an equivalent expression of p - 0.1p = 0.9p

The measure of arc JML in the given circle is 233°.

By definition, the measure of an arc is equal to the measure of the central angle that intercepts it. A central angle forms when two rays have their origins at the center of the circle and it also serves as the vertex of the central angle. We can note from the diagram that

arc JL is formed by the endpoints of the central angle ∠JKL=127°.

Thus, the measure of arc JL is equal to the measure of the angle or

arc JL=127°.

To find arc JML, we can note from the diagram that is equal to the rest of the circle. We know that the measure of a complete circle is 360°, so we can subtract arc JL from it and we get:

arc JML=360°-arc JL

=360°-127°

Step-by-step explanation:

If the total ticket sales was $ 2630, the theater sold 178 children's tickets, 99 student tickets, and 89 adult tickets.

Let's represent the number of children as "C", the number of students as "S", and the number of adults as "A".

We know that:

A = 0.5C (there are half as many adults as students)

C + S + A = 363 (the total number of people attending)

5C + 7S + 12A = 2630 (the total ticket sales)

We can use the first equation to substitute for A in the second and third equations:

C + S + 0.5C = 363

1.5C + S = 363

5C + 7S + 12(0.5C) = 2630

5C + 7S + 6C = 2630

11C + 7S = 2630

Now we have two equations with two variables (1.5C + S = 363 and 11C + 7S = 2630). We can solve for one variable in terms of the other in the first equation for tickets:

S = 363 - 1.5C

Substitute this expression for S in the second equation:

11C + 7(363 - 1.5C) = 2630

Simplify and solve for C:

11C + 2541 - 10.5C = 2630

0.5C = 89

C = 178

Now we can substitute this value for C in the expression we found for S:

S = 363 - 1.5(178)

S = 99

And we can use the first equation we found to solve for A:

A = 0.5C

A = 0.5(178)

A = 89

Thus, the theater sold 178 children's tickets, 99 student tickets, and 89 adult tickets.

The transformation of the graph f(x) = x² to the graph g(x) = -3(x+5)² + 12 involves a horizontal shift, a vertical stretch, and a vertical translation.

The graphs of f(x) = x² and g(x) = -3(x+5)² + 12 are the parabola.

The transformation of the graph is following as:

Firstly, the parabola has been shifted horizontally by 5 units to the left, which is reflected in the expression (x+5)².

Secondly, the parabola has been stretched vertically by a factor of -3, which is reflected in the coefficient in front of (x+5)².

Finally, the parabola has been raised up to 12 units. This means that the vertex of the parabola has been shifted upwards from the origin to the point (−5,12).

8/105 is the probability of selecting a red jelly bean the first draw and a blue jelly bean on the second draw, Therefore option C is correct.

The probability of selecting a red jelly bean on the primary draw is 8/(8+2+4+7) = 8/21, for the reason that there are 8 red jelly beans out of a complete of 8+2+4+7 = 21 jelly beans.

Since the jelly bean is not returned to the jar after the first draw, the number of jelly beans in the jar decreases through 1. consequently, on the second draw, there are 20 jelly beans left within the jar.

Out of those 20 jelly beans, 4 are blue. for that reason, the possibility of selecting a blue jelly bean on the second one draw, given that a red jelly bean was selected on the first draw, is 4/20 = 1/5.

To discover the probability of both events going on collectively & we multiply the probabilities of the 2 events:

P(red on 1st and Blue on 2d) = P(red on 1st) * P(Blue on 2nd | red on 1st)

P(red on 1st and Blue on 2nd) = (8/21) * (1/5)

P(red on 1st and Blue on 2nd) = 8/105

Therefore, the image coordinates of the vertices of triangle N'M'O' are: N'(-11, -2), M'(-8, -1), O'(-11, -5) that is option D.

In mathematics, a coordinate is a numerical value that specifies the position of a point in a geometric space, relative to a reference frame or origin. Coordinates are commonly used to describe the position of points in two-dimensional (2D) or three-dimensional (3D) space. In 2D space, a point can be described by its x-coordinate and y-coordinate. The x-coordinate represents the horizontal distance of the point from the origin, while the y-coordinate represents the vertical distance of the point from the origin. Together, the x-coordinate and y-coordinate specify the position of the point in the 2D space. In 3D space, a point can be described by its x-coordinate, y-coordinate, and z-coordinate. The x-coordinate represents the horizontal distance of the point from the origin, the y-coordinate represents the vertical distance of the point from the origin, and the z-coordinate represents the distance of the point along the depth or height axis. Together, the x-coordinate, y-coordinate, and z-coordinate specify the position of the point in the 3D space.

Here,

To determine the image coordinates of N'M'O' after translating the preimage 7 units to the left, we need to subtract 7 from the x-coordinates of each point.

The coordinates of N', M', and O' are obtained by subtracting 7 from the x-coordinates of N, M, and O respectively:

N' = (-4 - 7, -2) = (-11, -2)

M' = (-1 - 7, -1) = (-8, -1)

O' = (-4 - 7, -5) = (-11, -5)

Therefore, the image coordinates of N'M'O' are ON'(-11, -2), M'(-8, -1), O' (-11,-5). Answer option (D) is correct.

The set of data that represents the interquartile range and the maximum, in that order, is (80 - 70, 95), which simplifies to (10, 95).

Looking at the box plot, we can see that the box spans from approximately 65 to 85, with the median at around 75. To find the values for the interquartile range and maximum, we need to determine the exact values for Q1, Q3, and any outliers.

From the box plot, we can estimate that Q1 is around 70 and Q3 is around 80.

The median of the lower half of the data is the middle value between the smallest value and the median, which is approximately 68.

The median of the upper half of the data is the middle value between the median and the largest value, which is approximately 83.

To find the maximum value, we look for the highest data point that is not an outlier. From the box plot, we can see that there are no outliers, so the maximum value is the highest value in the data set, which is approximately 95.

Therefore, the set of data that represents the interquartile range and the maximum, in that order, is (80 - 70, 95), which simplifies to (10, 95).

Probability is  measure of  likelihood of  event occurring. It is number between 0 and 1, where 0 means that  event is impossible, and 1 means that  event is certain to occur. The probability of  event can be expressed as  fraction, a decimal, or a percentage. For example, if the probability of an event is 1/4, it means that there is a 25% chance of the event occurring.

The total number of hair clips in the box is:

Total number of hair clips = 15 (small) + 12 (medium) + 6 (large) = 33

The probability of selecting a small or medium hair clip is the sum of the probabilities of selecting a small hair clip and a medium hair clip:

P(small or medium) = P(small) + P(medium)

The probability of selecting a small hair clip is:

P(small) = number of small hair clips / total number of hair clips

= 15 / 33

The probability of selecting a medium hair clip is:

P(medium) = number of medium hair clips / total number of hair clips

= 12 / 33

Therefore, the probability of selecting a small or medium hair clip is:

P(small or medium) = P(small) + P(medium)

= 15/33 + 12/33

= 27/33

= 9/11
