Quartile- Divides a data set into four equal parts

Range- Difference between the highest and lowest data points

Interquartile- The difference between the upper quartile and the lower quartile

Given:

Price of new AirPods = $199.99

Tax rate = 9%

To find:

How much will he spend?

Solution:

We have,

Price of new AirPods = $199.99

Tax rate = 9%

Tax value = 9% of $199.99

                = \(\dfrac{9}{100}\times 199.99\)

                = \(17.9991\)

Now,

Total money spend = Price of AirPods + Tax

                                = \(199.99+17.9991\)

                                = \(217.9891\)

                                \(\approx 217.99\)

Therefore, the total money spend by James is $217.99.

Answer:

m<X = 27 degrees

Step-by-step explanation:

From △VWX, since WX = XV, this mean that the triangle is isosceles

The base angle of an isosceles triangle are equal hence <W = <X

Since <W = 27 degrees, hence m<X = 27 degrees

If the null hypothesis is true in a chi-squared test, then we expect the test statistic to be approximately equal to its expected value.

In a chi-squared test, the null hypothesis is the statement that there is no significant association between two variables. If the null hypothesis is true, then we expect the test statistic to be approximately equal to its expected value. The expected value is calculated using the degrees of freedom and the expected frequency of each category in the contingency table.

The chi-squared test statistic is calculated by subtracting the observed frequency from the expected frequency for each category and then squaring the result. These squared differences are then summed across all categories to calculate the chi-squared test statistic.

If the null hypothesis is true, we expect the test statistic to be close to its expected value. This is because when the null hypothesis is true, the observed frequencies should be close to the expected frequencies. Therefore, the squared differences should be small, resulting in a small test statistic.

Func 1 is unknown

This matches the placement of 10, 15, and 20 and hence the standard deviation will be the same in the two cases.

What is the standard deviation?

The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values are close to the set's mean, whereas a high standard deviation indicates that the values are spread out over a wider range.

Standard deviation determines how far numbers deviate from the mean. The Standard deviation of the two sets will be the same if the numbers from the respective means are placed in the same order.

This is what 10, 15, and 20 will be on a number line

10_ _ _ _15 _ _ _ _20

(15 is the mean and 10 and 20 are 5 steps away from the mean)

i) Z - X = 10

This is what Z and X will be on the number line

X _ _ _ _ _ Z

ii) Z - Y = 5

This is what Z and Y will on the number line.

Y_ _ _ _ _ Z

Together, their relative placement on the number line:

X _ _ _ _ _  Y  _ _ _ _ _  Z

This matches the placement of 10, 15, and 20 and hence the standard deviation will be the same in the two cases.

Answer:

C

Step-by-step explanation:

on C 1 ice cream cost $1.2 if you multiply 1.2x12=14.4

THE CORRECT ANSWER IS...

C ($9.59 for 8 scoops)

Step-by-step explanation:

well, if you divided 14.89 by 12 it equals $1.24. so that means it's $1.24 for one single scoop for that one. then for B if you divided $7.99 by 5, you'd get $1.60, so that's $1.60 per scoop for B. lastly $9.59 divided by 8 is $1.20, which is the lowest price per scoop, so that makes it the best and most affordable one. i hope i explained that easily, but basically all in all, the answer is C.

The proportion of STEM students who participate in at least one AP course is 0.19.

It can be deduced that the proportion of STEM students who participate in at least one AP course will be:

= 38/200

= 0.19

The proportion of regular students in the sample who participate in at least one AP course will be:

= 70/200

= 0.35

Also, participating in two or more AP courses is independent of student status. This is because the p value is more than the 0.05.

A method that could have been used to select a simple random sample of 200 students from the high school is by writing all the registration numbers of the students in a container an randomly picking.

There is bias in the sampling because the convenience sampling is used. This doesn't give everyone an equal chance.

In conclusion, status is not related to level of participation in AP courses.

Answer:

D

Step-by-step explanation:

Let's call the original diameter x. Then, the circumference would be xπ. If the diameter is 2x, the circumference is 2xπ. 2xπ / xπ = 2 so the answer is D.

Answer:

D. 2 times the circumference of the original circle

Step-by-step explanation:

The circumference of a circle is represented by the formula C = 2(r)pi (where is r is the radius), which can also be written as C = (d)pi, where d is the diameter, (since 2r is equivalent to d). If the diameter is doubled, the original equation can be rewritten as C = 2(d)pi. Therefore, the circumference of the new circle is double the original circle.

You can plug in a sample number to further prove this point. Pretend r = 3 so d = 6. C = 6pi. Now when the diameter is doubled, d = 12 and C = 12pi which is double 6pi.

So the answer is D. 2 times the circumference of the original circle

Answer:

(2, 1 )

Step-by-step explanation:

Using the Section formula

For endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n

Then coordinates of point are

[ \(\frac{mx_{2}+nx_{1} }{m+n}\) , \(\frac{my_{2}+ny_{1} }{m+n}\) ]

Here m = 5, n = 2, (x₁, y₁ ) = (- 3, - 9), (x₂, y₂ ) = (4, 5), thus partitioned point

= [ \(\frac{5(4)+2(-3)}{5+2}\) , \(\frac{5(5)+2(-9)}{5+2}\) ]

= [ \(\frac{20-6}{7}\) , \(\frac{25-18}{7}\) ]

= ( \(\frac{14}{7}\) , \(\frac{7}{7}\) )

The 99% confidence interval for the difference in the proportions of people from City A and City B who prefer New Spring soap is given by the lower limit and upper limit.

To calculate the confidence interval for the difference in proportions, we can use the formula for the confidence interval for the difference between two proportions:

p1 - p2 ± Z * sqrt((p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)),

where p1 and p2 are the proportions of people from City A and City B who prefer New Spring soap, n1 and n2 are the sample sizes of City A and City B, and Z is the z-score corresponding to the desired level of confidence (in this case, 99%).

From the given information, we have p1 = 121/294 ≈ 0.412 and p2 = 149/409 ≈ 0.364. The sample sizes are n1 = 294 and n2 = 409.

We can substitute these values into the formula along with the z-score for a 99% confidence level (which corresponds to approximately 2.576) to calculate the confidence interval for the difference in proportions.

After performing the calculations, we find the lower limit and upper limit of the confidence interval, rounded to three decimal places.

The correct inequalities that alana wrote is

B) 0> -34

D) -80< 12

(a) The conditional probability density for X, given Y = 2, is 2 \(e^{-2x}\). (b) X and Y are not independent because their joint probability density function cannot be expressed as the product of their individual probability density functions.

(a) To compute the conditional probability density for X, given Y = 2, we use the conditional probability density function formula:

f(x|Y=2) = f(x, 2) / fY(2),

where f(x, 2) is the joint probability density function and fY(2) is the marginal probability density function of Y evaluated at y = 2.

The joint probability density function f(x, y) is given as 2/3 \(y^{2} e^{-xy}\), and since we are considering Y = 2, we substitute y = 2 into the joint probability density function:

f(x, 2) = 2/3 \((2^2) e^{-2x}\) = 8/3 \(e^{-2x}\)

The marginal probability density function of Y, denoted as fY(y), can be obtained by integrating the joint probability density function over the range of x:

fY(y) = ∫[0,∞] f(x, y) dx.

To find fY(2), we integrate f(x, y) = 2/3 \(y^{2} e^{-xy}\) with respect to x from 0 to infinity:

fY(2) = ∫[0,∞] (2/3) \((2^2) e^{-2x}\) dx = (8/3) ∫[0,∞] \(e^{-2x}\) dx.

Evaluating the integral gives fY(2) = 4/3.

Therefore, the conditional probability density for X, given Y = 2, is:

f(x|Y=2) = f(x, 2) / fY(2) = (8/3 \(e^{-2x}\)) / (4/3) = 2 \(e^{-2x}\).

(b) X and Y are not independent because their joint probability density function f(x, y) = 2/3 \(y^{2} e^{-xy}\) cannot be factored into the product of their individual probability density functions, i.e., f(x, y) ≠ fX(x) fY(y).

Independence between random variables requires the joint probability density function to be separable into the product of their marginal probability density functions, which is not the case here.

Therefore, X and Y are dependent random variables.
