costume and small packages of gummies to kids
without a costume. The candy bars cost $0.80,
and the gummies cost $0.25. At the end of the
night, 100 children visited Mrs. Jones's home,
and she gave out $69.00 in candy. How many
children who visited Mrs. Jones's home were
wearing a costume?
A. 20
B. 50
C. 69
D. 80
E. 92
ANSWER. BBB
Step-by-step explanation:
Mrs. Jones gave candy bars to 80 children who were wearing costumes. The correct answer is option D.
The question is a classic example of a system of equations problem
Let's call the number of children with costumes x and the number without costumes y. We have two pieces of information that will help us solve for x:
The total number of children is 100, so x + y = 100.
The total amount of money spent on candy is $69, and since candy bars cost $0.80 and gummies cost $0.25, we can express this as 0.80x + 0.25y = 69.
We can solve this system of equations using substitution or elimination method.
Let's use substitution and express y in terms of x from the first equation: y = 100 - x.
Now we substitute this into the second equation:
0.80x + 0.25(100 - x) = 69
0.80x + 25 - 0.25x = 69
0.55x = 44
Solving for x gives us x = [tex]\frac{44}{0.55}[/tex]
Therefore, 80 children wearing costumes were given candy bars by Mrs. Jones. The correct answer is D.

A sports physician conducts an observational study to learn the average amount of time that 3,000 swimmers in the town can hold their breath underwater. He uses 150 sampling of 60 people. The average of the means of all the samplings is 72.7, and the standard deviation is 0.92. This is a histogram of the sampling distribution of the sample mean. Based on this data, with a 95% confidence interval the researchers can determine that the actual average amount of time the entire population can hold their breath under water is? Between and
Answer:
95% confidence interval for the actual average amount of time the entire population can hold their breath under water is between 72.55 and 72.85.
Step-by-step explanation:
Confidence Interval for the population mean is basically an interval of range of values where the true population mean can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample mean) ± (Margin of error)
Sample Mean = 72.7
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error of the mean)
Critical value will be obtained using the t-distribution. This is because there is no information provided for the population mean and standard deviation.
To find the critical value from the t-tables, we first find the degree of freedom and the significance level.
Degree of freedom = df = n - 1 = 150 - 1 = 149
Significance level for 95% confidence interval
(100% - 95%)/2 = 2.5% = 0.025
t (0.025, 1499) = 1.975 (from the t-tables)
Standard error of the mean = σₓ = (σ/√n)
σ = standard deviation of the sample = 0.92
n = sampling size = 150
σₓ = (0.92/√150) = 0.0751176854 = 0.07512
95% Confidence Interval = (Sample mean) ± [(Critical value) × (standard Error of the mean)]
CI = 72.7 ± (1.975 × 0.07512)
CI = 72.7 ± 0.1483574288
95% CI = (72.55, 72.85)
95% Confidence interval = (72.55, 72.85)

In an all boys school, the heights of the student body are normally distributed with a mean of 71 inches and a standard deviation of 2.5 inches. Using the empirical rule, determine the interval of heights that represents the middle 95% of male heights from this school.
The Empirical Rule is being used to calculate the height distribution for the male students at a school. Based on the mean height of 71 inches and standard deviation of 2.5 inches, the height interval that represents the middle 95% of the male heights at this school is approximately from 66 to 76 inches.
Explanation:In the context of this question, we're using statistics, specifically the Empirical Rule, to find a range that represents the middle 95% of heights for the male students. The Empirical Rule states that, in a normal distribution:
About 68% of values fall within 1 standard deviation of the mean About 95% of values fall within 2 standard deviations of the mean About 99.7% of values fall within 3 standard deviations of the mean
Here, the mean height is 71 inches and the standard deviation is 2.5 inches, so applying the Empirical Rule- two standard deviations from the mean would capture about 95% of the heights:
Lower limit = Mean - 2(Standard Deviation)
= 71 - 2(2.5) = 66 inches
Upper limit = Mean + 2(Standard Deviation)
= 71 + 2(2.5) = 76 inches
So the height interval that represents the middle 95% of heights for the males at this school is 66 to 76 inches.

Using the empirical rule and a normal distribution with a mean of 71 inches and a standard deviation of 2.5 inches, the middle 95% interval of male heights is between 66 inches and 76 inches.
Explanation:The student from the all-boys school is asking about an application of the empirical rule in statistics, which is useful for understanding data that follows a normal distribution. To find the interval that represents the middle 95% of heights, we apply the empirical rule, which states that 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. Since we are interested in the middle 95%, we calculate the interval by subtracting and adding two standard deviations from the mean.
Calculation steps:
Therefore, the middle 95% of the males heights from this school fall between 66 inches and 76 inches.

Find the perimeter of each polygon. Assume that lines which appear to be tangent are tangent.
Answer:
The perimeter would be 60 units; Option B
Step-by-step explanation:
~ Let us consider this problem. We know that tangent segments are congruent to one another provided they are from one endpoint. According to that, we would note that several segments are congruent to one another... ~
1. All the tangent segments that "sprout" from one vertex in this plane onto the circle circumscribed in this triangle are congruent, as noted before. According to that the side of the length 18 units has one part equivalent to 8.7 units.
2. With that being said the other part of the side with length 18 units, would be 18 - 8.7 = 9.3 units. Respectfully the side with length of 21.3 units has a part that is congruent to 9.3, by tangent ≅. This other part of the side with 21.3 units now = 21.3 - 9.3 = 12 units. Similarly the side with 8.7 as a part of it, has the other part ≅ to 12 units, it's measure thus also being 12 units.
3. Let us see the measures we have at this point. The perimeter would be ⇒ 8.7 + 8.7 + 9.3 + 9.3 + 12 + 12 = 60 units
If the probability of a chance event is 0, it is _________ to happen when compared to a chance event with a probability of 1.
If the probability of an event is 0, it is impossible to happen, in contrast to an event with a probability of 1, which is certain to happen. Probability is measured between 0 (impossible event) and 1 (certain event), with a familiar example being a coin flip where each outcome (heads or tails) has an equal probability of 0.5.
If the probability of a chance event is 0, it is impossible for it to happen when compared to a chance event with a probability of 1, which is certain to happen. The concept of probability is expressed as a number between zero and one, inclusive. An event with a probability of 0 is not expected to happen at all, while an event with a probability of 1 is considered an absolute certainty. In contrast, if two events are mutually exclusive, the probability that they both happen at the same time is zero (P(A AND B) = 0). A familiar example involving probability is flipping a fair coin, where there's a 1/2 chance of getting heads, meaning that the outcome of getting either heads or tails are equally likely; each has a probability of 0.5.

Which transformation will be equivalent to rotating a figure 90° counterclockwise
Answer:
Reflecting over the x-axis and then reflecting over the line y = x.
Step-by-step explanation:
A rotation 90° counterclockwise will map every point (x, y) to (-y, x).
Since the x- and y-coordinates are switched, this is not a reflection across the x-axis followed by a reflection across the y-axis.
Since the y-coordinate is negated and the x- and y-coordinates are switched, this is not a translation.
Reflecting across the x-axis will negate the y-coordinate, giving us (x, -y). Following this with a reflection across y=x will switch the coordinates giving us (-y, x). This is the correct transformation.

Answer:
A good combination will be equal to or greater than 80 ft³. Example
r = 3 ft
h = 5 ft
volume = πr²h
volume = 3.14 × 9 × 5 = 3.14 × 45 = 141.3 ft³ is a good combination of radius and height .
Step-by-step explanation:
The volume of a cylinder = πr²h
Jeff is planning on building a cylindrical water tank that has a capacity of no less than 80 ft³. This means he want the volume of the cylindrical tank to be equal to or greater than 80 ft³(volume ≥ 80 ft³). The combinations of radius and height should be equal to or greater than 80 ft³ when they are inserted in the volume formula of a cylindrical water tank.
For example
volume = πr²h
r = 2 ft
h = 5 ft
volume = πr²h
volume = 3.14 × 2² × 5 = 62.8 ft³ is not a good combination of base radius and height because the volume is less than 80 ft³.
A good combination will be equal to or greater than 80 ft³. Example
r = 3 ft
h = 5 ft
volume = πr²h
volume = 3.14 × 9 × 5 = 3.14 × 45 = 141.3 ft³ is a good combination of radius and height .

What is the length and width?
Answer:
L. W = 60. 30.
Step-by-step explanation:
Perimeter = 2L + 2W where W = width and L = the length, and L = 2W.
We have the following system:
2L + 2W = 180
L = 2W
Substituting L = 2W in the first equation we have:
2(2W) + 2W = 180
4W + 2W = 180
6W = 180
W = 180/6 = 30.
So L = 2*30 = 60.
