Answer: $4.20
Step-by-step explanation:
To answer this question, we will find 5% of $84.
First, a percent divided by 100 becomes a decimal.
5% / 100 = 0.05
Next, we are finding 5% of $84. In mathematics, "of" means multiplication.
0.05 * $84 = $4.20
in a randomized controlled trial, sometimes patients agree to receive an intervention but later decide to stop taking the medication. moreover, some patients who were assigned to placebo decide to stop taking the placebo pill and buy the drug on their own (even when they do not know that they are taking a placebo pill). when this happens, researchers typically do the analysis according to the original assignment of the treatment regardless of the actual treatment received. what is the name of this procedure to analyze the data?
The procedure used to analyze the given data is intention-to-treat analysis.
The procedure to analyze data according to the original assignment of the treatment regardless of the actual treatment received is called the intention-to-treat (ITT) analysis. It is considered the gold standard in clinical trial analysis because it preserves the randomization and avoids bias that may arise from differential dropouts or non-compliance. By analyzing all patients according to their randomized group, the ITT analysis provides an unbiased estimate of the treatment effect and better reflects the real-world effectiveness of the intervention.
The intention-to-treat (ITT) analysis is different from other types of analyses because it includes all patients according to their original randomized group, regardless of whether they received the assigned treatment or not. This is in contrast to per-protocol analysis, where only patients who completed the study without any major protocol deviations are included, or as-treated analysis, where patients are analyzed according to the actual treatment received.

a box next to the register at tacos and stuff, where cooper works, is filled with different-flavored sauce packets. when a customer asks for some spicy sauce packets, cooper reaches into the box and pulls out a large handful of packets, looking for the spicy ones. here are the flavors he pulls out: mild, mild, spicy, medium, spicy, mild, spicy, super-hot, mild, spicy, super-hot, mild, mild based on the data, what is the probability that the next packet cooper pulls out of the box will be spicy?
Based on the given data, there are a total of 13 packets and 5 of them are spicy. Therefore, the probability that the next packet Cooper pulls out of the box will be spicy is 5/13 or approximately 0.385 (rounded to three decimal places).
To calculate the probability of the next packet being spicy, we need to know how many packets of each flavor are in the box. Assuming that Cooper doesn't put back the packets he has pulled out, we can count the number of spicy packets and divide it by the total number of packets he pulled out.
In this case, out of the 13 packets he pulled out, 5 were spicy. Therefore, the probability of the next packet being spicy is 5/13, or approximately 0.38, or 38%. However, if the box is refilled with packets of different flavors, this probability may not hold.

Use the number line to think about the location of the number 2 and the number n, where n is greater than 3. write an inequality comparing the opposite of 2 and the opposite of n. explain how the number line shows that your inequality is correct
We can use the number line to see that 2 and any number greater than 3 are to the right of -4 1/2. By finding the Opposites of 2 and n and comparing them, we can write an inequality that is correct based on the number line.
The opposite of -4 1/2 is 4 1/2. This is because the opposite of a number is the number that is the same distance from 0 on the number line, but in the opposite direction. On a number line, -4 1/2 is to the left of 0, so its opposite, 4 1/2, is to the right of 0.
Looking at the number line, we can see that the number 2 is to the right of -4 1/2, but to the left of 4 1/2. Any number greater than 3, represented by n, is also to the right of -4 1/2.
The opposite of 2 is -2 and the opposite of n is -n. So, the inequality we can write is:
-n < -2
This is because -2 is to the left of -n on the number line. We can see that this inequality is correct on the number line because -2 is closer to 0 than -n, which means that -n is less than -2.
In summary, the opposite of -4 1/2 is 4 1/2, and it is related to -4 1/2 because they are the same distance from 0 on the number line, but in opposite directions. We can use the number line to see that 2 and any number greater than 3 are to the right of -4 1/2.

The vertices of a rhombus are located at the coordinates (1, 3), (4, 7), (9, 7),
and (6, 3)
Find the length of the horizontal sides of the rhombus and its perimeter.
Answer: To find the length of the horizontal sides of the rhombus, we need to find the distance between points (1, 3) and (9, 7), which is the same as the distance between points (4, 7) and (6, 3).
Using the distance formula:
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(9 - 1)² + (7 - 3)²]
d = √[64 + 16]
d = √80
d ≈ 8.94
So the length of the horizontal sides of the rhombus is approximately 8.94 units.
To find the perimeter of the rhombus, we need to find the distance between all four vertices and add them up.
Using the distance formula:
d₁ = √[(4 - 1)² + (7 - 3)²] = √25 = 5
d₂ = √[(9 - 4)² + (7 - 7)²] = √25 = 5
d₃ = √[(6 - 9)² + (3 - 7)²] = √16 + 16 = √32 ≈ 5.66
d₄ = √[(1 - 6)² + (3 - 7)²] = √25 + 16 = √41 ≈ 6.40
Perimeter = d₁ + d₂ + d₃ + d₄ = 5 + 5 + 5.66 + 6.40 ≈ 22.06
So the perimeter of the rhombus is approximately 22.06 units.

Travis has the following books on his shelf: 6 myster, 5 science, 4 history, and 3 adventure. Travis will randomly choose 1 book to read. What is the probability (in fraction form) that he will choose a mystery book?
Answer: The probability that Travis will choose a mystery book is 1/3.
Step-by-step explanation: To find the probability that Travis will choose a mystery book, we need to determine the ratio of the number of mystery books to the total number of books on Travis's shelf.
Travis has 6 mystery books, and the total number of books on his shelf is 6 + 5 + 4 + 3 = 18.
Therefore, the probability (in fraction form) that Travis will choose a mystery book is 6/18.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 6.
6 ÷ 6 = 1
18 ÷ 6 = 3
So, the simplified fraction is 1/3.
the empirical rule assumes that the distribution of data follows a normal curve. group startstrue or false
The statement "The empirical rule assumes that the distribution of data follows a normal curve." is True.
The empirical rule, also known as the 68-95-99.7 rule, is a statistical rule that states that for a normal distribution, approximately 68% of the data will fall within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. This implies that the distribution of data follows a normal curve.
A normal distribution is a type of probability distribution that follows a symmetrical bell-shaped curve. It is also known as the Gaussian distribution and is a continuous probability distribution. The normal distribution is defined by its mean, which is the average of the values, and its standard deviation, which is a measure of the spread of the values from the mean.

Nicole is 1.55 meters tall. At 2 p.m., she measures the length of a tree's shadow to be 30.05 meters. She stands 25.6 meters away from the tree, so that the tip of her shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.
Answer:
approximately 1.81 meters.
Step-by-step explanation:
Let's call the height of the tree "h". We can set up a proportion based on the similar triangles formed by Nicole, her shadow, the tree, and the tree's shadow:
(height of Nicole) / (length of Nicole's shadow) = (height of tree) / (length of tree's shadow)
Substituting the given values, we get:
1.55 / 25.6 = h / 30.05
Simplifying and solving for h, we get:
h = (1.55 / 25.6) * 30.05
= 1.81181640625
Rounding to the nearest hundredth, we get:
h ≈ 1.81 meters
the height of the tree is approximately 1.81 meters.

(note: some answers are rounded to two decimal places.)
We can start by creating a table to organize the information:
Likes Chocolate (c) Does Not Like Chocolate (~c) Total
Likes Sprinkles (s) 0.25 0.40
Does Not Like Sprinkles (~s) 0.60
Total 0.70 0.30 1.00
We are given that 40% of friends like sprinkles, so we can fill in that cell of the table. We are also given that 25% of friends who like chocolate also like sprinkles, so we can fill in the cell for likes chocolate and likes sprinkles as 0.25.
To find the proportion of friends who like sprinkles and chocolate, we need to divide the number of friends who like both by the total number of friends who like sprinkles:
proportion = likes chocolate and sprinkles / likes sprinkles
proportion = 0.25 / 0.40
proportion = 0.625
So, approximately 62.5% of friends who like sprinkles also like chocolate.

What is quadratic function?A polynomial function of degree 2 is a quadratic function, while one of degree 1 is a linear function. The formula for a quadratic function is f(x) = ax² + bx + c, where a, b, and c are constants and an is not equal to 0. A parabola, a U-shaped curve, is the graph of a quadratic function. Depending on the sign of the leading coefficient, the function's minimum or maximum value is located at the parabola's vertex.
a) The highest value of the population function, which is a quadratic function with a negative leading coefficient, occurs near the parabola's vertex.
Thus, t = -b/2a.
Substituting the values a = -1698, b = 85,000, and c = 10,000 we have:
t = -85000 / 2(-1698) = 25
Therefore, the time at which the population is at a maximum is 25 hours.
b) To determine the maximum population we substitute the value of t = 25.
p(25) = -1698(25)² + 85,000(25) + 10,000 = 1,182,500
Therefore, the maximum population is 1,182,500.

Determine whether the graph of the equation is symmetric with respect to the
The graph of the equation y = x² + 5 is symmetric with respect to the y-axis, the correct option is (b).
To determine the symmetry of the graph, we can substitute (-x) for x in the equation and simplify:
y = (-x)² + 5
y = x² + 5
Since the equation is unchanged when x is replaced by (-x), the graph is symmetric with respect to the y-axis.
We can also see that the graph is not symmetric with respect to the x-axis or the origin. To check for symmetry with respect to the x-axis, we can substitute (-y) for y in the equation:
(-y) = x² + 5
y = -(x² + 5)
The equation is not the same as the original equation, so the graph is not symmetric with respect to the x-axis. Similarly, to check for symmetry with respect to the origin, we can substitute (-x) and (-y) for x and y in the equation:
(-y) = (-x)² + 5
y = x² + 5
The equation is not the same as the original equation, so the graph is not symmetric with respect to the origin.
