A ranked frequency distribution of data can be created by sorting the data in ascending or descending order and then counting the frequency of each value.

The given data set is 245, 261, 289, 222, 291, 289, 240, 233, 249, and 200. To create a ranked frequency distribution of this data set, we first need to sort it in ascending or descending order. Let's sort it in ascending order:200, 222, 233, 240, 245, 249, 261, 289, 289, 291 Next, we need to count the frequency of each value. We can do this by going through the data set and counting how many times each value occurs. Here is the frequency distribution table:Value Frequency 200 1222 1233 1240 1245 1249 1261 1289 2291 1 From this table, we can see that the most frequent value is 289, which occurs twice. We can also see that the least frequent values are 200, 222, 233, and 240, which each occur only once.

In conclusion, a ranked frequency distribution of data can be created by sorting the data in ascending or descending order and then counting the frequency of each value. This allows us to see which values are most and least frequent in the data set.

The variance for the sample mean is 0.0001 cm².

To find the variance for the sample mean of 4 computer chips with a mean of 0.95 centimeters and a standard deviation of 0.02 centimeters, you can follow these steps:

1. Note the population mean (µ) = 0.95 cm and population standard deviation (σ) = 0.02 cm.
2. Identify the sample size (n) = 4.
3. Calculate the variance for the sample mean using the formula: variance of sample mean = (σ²) / n.

In this case, the variance of the sample mean is:

Variance of sample mean = (0.02 cm)² / 4 = 0.0004 cm² / 4 = 0.0001 cm².

So, the variance for the sample mean of the 4 computer chips is 0.0001 cm².

Answer:

Easy it 6.4 you get it by dividing.

Step-by-step explanation:

Therefore, the answer is option C: theta = pi/2 and theta = 3pi/2.

To determine when tan(theta) is undefined on the unit circle, we need to remember the definition of the tangent function.
Tangent is defined as the ratio of the sine and cosine of an angle. Specifically, tan(theta) = sin(theta)/cos(theta).

Now, we know that cosine can never be equal to zero on the unit circle, since it represents the x-coordinate of a point on the circle and the circle never crosses the x-axis. Therefore, the only way for tan(theta) to be undefined is if the cosine of theta is equal to zero.
There are two values of theta on the unit circle where cosine is equal to zero: pi/2 and 3pi/2.

At theta = pi/2, we have cos(pi/2) = 0, which means that tan(pi/2) = sin(pi/2)/cos(pi/2) is undefined.
Similarly, at theta = 3pi/2, we have cos(3pi/2) = 0, which means that tan(3pi/2) = sin(3pi/2)/cos(3pi/2) is also undefined.
Therefore, the answer is option C: theta = pi/2 and theta = 3pi/2.

Yes, if you have minimums and maximums that are several standard deviations away from the rest of the data observations, medians would be the best measure of central tendency.

Having minimums and maximums that are far away (several standard deviations away from the mean) from the rest of the data observations, medians would be the best measure of central tendency. This is because, when there are outliers or extreme values in a dataset, the mean can be influenced and it may not be an accurate representation of the central tendency.

However, the median is not affected by extreme values or outliers since it only depends on the middle value of the dataset. Therefore, if the dataset has outliers, it is better to use the median as a measure of central tendency to provide a more accurate representation of the data.

The radian measure of the angle at the center of the circle is approximately 1.6623 radians.

We are given that the radius of the circle is 77.0 cm and the length of the intercepted arc is 128 cm. We need to find the radian measure of the angle at the center of the circle.

To solve this problem, we use the formula relating the angle at the center of a circle, the radius of the circle, and the arc length intercepted by the angle.

The formula is given byθ = s/rwhereθ = angle at the center of the circle in radians s = arc length intercepted by the angle r = radius of the circle Substituting the given values, we getθ = 128/77.0 = 1.6623 radians (rounded to four decimal places)

Therefore, the radian measure of the angle at the center of the circle is approximately 1.6623 radians.

Jake's claim that he made twice as many 2-pointers as 3-pointers based on the sums of the factors is invalid as it does not consider the number of shot attempts.

Jake's claim that he made twice as many 2-pointers as 3-pointers because 4+6 is greater than 1+2 is not correct. This is because the number of shots he made cannot solely be determined by the sum of the factors in each shot type.

It is possible for Jake to have made more 3-pointers despite the smaller sum of factors, as long as he attempted more shots from that range.

Therefore, without additional information about the number of attempts he made for each shot type, it is not valid to conclude that he made twice as many 2-pointers as 3-pointers solely based on the sums of the factors.

Answer:

a. 9

b. 9.

Step-by-step explanation:

a) √1098 = 33.136

33^3 = 1089

So the answer is 1098 - 1089

= 9.

b) √4498 = 67.067

67^2 =  4489

Answer = 9.

Answer:

a). 9

b). 9

Step-by-step explanation:

a) If you try to subtract 1 to 8 from 1098, it won't make a perfect square. But if you subtract 9 from 1098 (that will make it 1089), it will make a perfect square.

√1089 = 33

33² = 33 × 33 = 1089

So the answer is 9.

b). If you try to subtract 1 to 8 from 4498, it won't make a perfect square. But if you subtract 9 from 4498 (that will make it 4489), it will make a perfect square.

√4489 = 67

67² = 67 × 67 = 4489

So the answer is 9.

Let y = number of orangutans, and let x = number of years.

For each study, the population, y, after x years is:

First study:

y = 784 - 25x

Second study:

y = 817 - 36x

We set the populations equal and solve for x, the number of years.

784 - 25x = 817 - 36x

Add 36x to both sides. Subtract 784 from both sides.

11x = 33

Divide both sides by 11.

Step-by-step explanation:

Hey there!

Here;

The one end is A(-1,4) and midpoint M(3,0).

Let another endpoint be B(x,y).

Using midpoint formula.

\((x,y) = (\frac{x1 + x2}{2} , \frac{y1 + y2}{2} )\)

Put all values.

\((3,0) = ( \frac{ - 1 + x}{2} ,\frac{4 + y}{2} )\)

Since, they are equal, equating with their corresponding elements we get.

\(3 = \frac{ - 1 + x}{2} \)

6 = -1 +x

x= 7.

Again,

\(0 = \frac{4 + y}{2} \)

0 = 4+y

y = -4

Therefore the another endpoint is (7,-4).

Step-by-step explanation:

Based on the provided output, the conclusion that can be drawn is that the data provide sufficient evidence to reject the null hypothesis and conclude that the mean number of minutes exercised per week is lower for men than for women.

In hypothesis testing, the null hypothesis assumes that there is no difference between the mean number of minutes exercised per week for men and women. The alternative hypothesis, in this case, is that the mean number of minutes per week is lower for men.

The t-value of -1.9909 and the associated p-value of 0.02421 indicate that the test statistic falls in the critical region at the 5% significance level. Since the p-value is less than the significance level, we reject the null hypothesis. This means that there is sufficient evidence to support the alternative hypothesis that the mean number of minutes exercised per week is lower for men than for women.

Furthermore, the 95 percent confidence interval upper bound for the difference in means (-0.6750134) being negative supports the conclusion that the mean number of minutes exercised per week is lower for men.

Therefore, the correct conclusion is option a: The data provide sufficient evidence to reject the null hypothesis and to conclude that the mean number of minutes exercised per week is lower for men than for women.

Let the side of the original square be a. We are given that the area of the new garden was (a - x)(a + x) = a² - x² = 64.

We want to find the area of the original square, so the value of a².

(1) The area of the new garden was 80 percent of the area of the original square garden --> 64 = 0.8a² --> a² = 80. Sufficient.

(2) x = 4 --> a² - 4² = 64 --> a² = 80. Sufficient.

the area is the quantity that expresses the quantity of a location on the aircraft or on a curved surface. The place of an aircraft region or plane vicinity refers back to the location of a form or planar lamina, at the same time as floor area refers to the place of an open surface or the boundary of a 3-dimensional object. location may be understood as the quantity of fabric with a given thickness that might be vital to style a model of the form, or the amount of paint necessary to cowl the surface with an unmarried coat. it's by far the two-dimensional analog of the duration of a curve (a one-dimensional idea) or the volume of a strong (a three-dimensional concept).

place plays a vital position in current mathematics. further to its apparent importance in geometry and calculus, the place is associated with the definition of determinants in linear algebra and is a simple asset of surfaces in differential geometry.
