Emma would have approximately $4,723 more than Juan.

To solve given problem, we will use the formula for compound interest:

\(A=P(1+\frac{r}{n})^{nt}\)

A = amount

P = principal investment

r = interest rate

t = number of years.

For Emma's account, we have:

P = $90,000

r = 3.375% = 0.03375 (since 3 (3/8) % is equivalent to 0.03375 as a decimal)

n = 365

t = 17 years

So, we can calculate the amount of money in Emma's account after 17 years as:

A = $90,000(1 + 0.03375/365)⁽³⁶⁵⁾⁽¹⁷⁾

A = $ 159,737.70

For Juan's account, we have:

P = $90,000

r = 3.25% = 0.0325 (since 3 (1/4) % is equivalent to 0.0325 as a decimal)

n = 1

t = 17 years

So, we can calculate the amount of money in Juan's account after 17 years as:

A = $90,000(1 + 0.0325)¹⁷

A = $155,014.93

Therefore, Emma would have more money in her account than Juan after 17 years by:

$ 159,737.70 - $155,014.93 = $4,722.77

Rounding to the nearest dollar, Emma would have approximately $4,723 more than Juan.

One-way ANOVA is a statistical procedure that is used for comparing the means of several populations. Also, it is the generalization of pooled t-procedure for comparing the means of two populations.

A mean is also referred to as an arithmetic average and it can be defined as a ratio of the sum of the total number in a data set (population) to the frequency of the data set.

ANOVA is an abbreviation for analysis of variance which was developed by the notable statistician Ronald Fisher. The analysis of variance (ANOVA) is a collection of statistical models with their respective estimation procedures that are used for the analysis of the difference between the group of means found in a sample.

This ultimately implies that, the analysis of variance (ANOVA) helps to ensure we have a balanced data by splitting the observed variability of a data set into random and systematic factors.

In Statistics, the analysis of variance (ANOVA) procedure is typically used as a statistical tool to determine whether or not the means of two or more populations are equal, especially through the use of the following:

In this context, we can infer and logically deduce that a one-way ANOVA is a statistical procedure that is used for comparing the means of several populations. Also, it is the generalization of pooled t-procedure for comparing the means of two populations.

The equation u = 8wz represents a joint variation, and the constant of variation is 8.

The equation u = 8wz represents a direct variation. This means that u varies directly with the product of w and z, meaning that as w and z increase or decrease, u also increases or decreases at the same rate. The constant of variation in this equation is 8, which represents the ratio of u to the product of w and z. This means that if w and z are both multiplied by a certain factor, u will also be multiplied by the same factor times 8. For example, if w is doubled and z is tripled, u will be multiplied by 6 times 8, or 48. Direct variation equations are often written in the form y = kx, where k is the constant of variation. However, in this case, the equation is in a different form, but still represents the same concept of direct variation.

In summary, the equation u = 8wz represents a joint variation, and the constant of variation is 8.

The polynomial 6x2 + 3x + 1 represents the calculator's surface area in standard form.

The problem asks us to find the polynomial that represents the area of the calculator, given that the width of the calculator is represented by (3x+1) inches and the length is twice the width. The formula for the area of a rectangle is A = L x W, where A is the area, L is the length, and W is the width.

We are given that the width is (3x+1) inches, and the length is twice the width, so the length is 2(3x+1) = 6x+2 inches. We can now substitute these values into the formula for the area to get:

A = (6x+2)(3x+1)

Expanding the product, we get:

A = \(18x^2 + 12x + 2\)

So the polynomial that represents the area of the calculator is \(18x^2 + 12x + 2\), written in standard form.

The value of surd expression x²+ xy + y² by means of simplification of surds is 3.

The solution to the surd  is derived as follows:

x = √3-√2 /√3+√2 and

y = √3+√2 /√3-√2

The value of x²+ xy + y² is calculated as follows:

x² = (√3-√2 /√3+√2)²

x² = 5 - 2√6 / 5 + 2√6

y² = (√3+√2 /√3-√2)²

y² =  5 + 2√6 / 5 - 2√6

xy = (√3-√2 /√3+√2) (√3+√2 /√3-√2)

Let's start by finding the length of one edge of the original cube.

The surface area of a cube can be expressed as 6s^2, where s is the length of one edge.

So we have:

6s^2 = 2400

Solving for s, we get:

s = sqrt(2400/6)

s = 20

Therefore, the original cube has an edge length of 20 cm.

To find the volume of the similar box enlarged by a scale factor of 1.5, we need to multiply the volume of the original cube by (1.5)^3, since the scale factor applies to all three dimensions (length, width, and height).

The volume of the original cube is:

V = s^3 = 20^3 = 8000 cm³

So the volume of the similar box is:

V' = V x (1.5)^3 = 8000 x 1.5^3 = 8000 x 3.375 = 27000 cm³

Therefore, the volume of the similar box enlarged by a scale factor of 1.5 is 27,000 cm³.

Relative age dating determines the sequence of events without providing specific ages, while radiometric age dating calculates precise numerical ages using radioactive isotopes. Relative age dating is limited by its inability to assign exact ages, while radiometric age dating is limited by the availability of suitable isotopes and its applicability to specific time ranges.

Relative age dating involves comparing the positions of rocks or fossils in different layers or formations to determine their relative ages. It relies on principles such as superposition, cross-cutting relationships, and fossil succession. It can provide information about the sequence of events and the relative order of geological features. However, it does not provide precise numerical ages and is limited to establishing relative age relationships.

Radiometric age dating, on the other hand, uses the decay of radioactive isotopes in rocks and minerals to determine their absolute ages. By measuring the ratio of parent isotopes to daughter isotopes, scientists can calculate the time elapsed since the rock or mineral formed. Radiometric age dating provides precise numerical ages and is particularly useful for dating ancient rocks and fossils. However, it requires the presence of suitable isotopes, and some isotopes may have long half-lives, limiting their applicability to certain time ranges.

In summary, relative age dating provides information about the sequence of events but not specific ages, while radiometric age dating provides precise numerical ages but relies on the availability of suitable isotopes and has limitations in terms of the time range it can cover.

Step-by-step explanation:

measures of complementary angles always add up to 90°

                                (3y - 1) + (4y + 7) = 90  

                                3y + 4y - 1 + 7 = 90

                                       7y + 6 = 90

                                         7y = 90 - 6

                                           7y = 84

                                            y = 84/7

Tim purchased 6 video games.

Step-by-step explanation:

Let's set the number of games Time purchased as x.

Due to each game costing $25, the total amount of money used on buying games would be ($25)x.

Hence, as the total amount of money used to buy both the console and the video games would be $350, the equation can be set as:

\(\$25x + \$200 = \$350\)

\(\$25x = \$(350 - 200)\)

\(x = \frac{\$150}{\$25}\)

\(x = 6\)

Therefore, Tim purchased 6 video games.

Equation of the Line

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

\(\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\)

The line passes through the points (6,-8) and (-3,7), thus:

\(\displaystyle y+8=\frac{7+8}{-3-6}(x-6)\)

\(\displaystyle y+8=\frac{15}{-9}(x-6)\)

Simplifying:

\(\displaystyle y+8=-\frac{5}{3}(x-6)\)

Multiplying by 3:

\(3(y+8)=-5(x-6)\)

\(3y+24=-5x+30\)

Moving all the variables to the left side:

3y + 5x = 30 - 24

3y + 5x = 6

(a) Mean = (9 + 15 + 18 + 11 + 12) / 5 = 65 / 5 = 13

(b) Mean of the sample = (9 + 15) / 2 = 24 / 2 = 12

(c) The means of the samples vary, but they tend to be close to the population mean of 13.

(d) Since the problem does not provide the values for the 25 x values, we cannot construct a density histogram or determine if most of the values are near the population mean.

(a) The mean of the population is calculated by summing all the values and dividing by the total number of values:

Mean = (9 + 15 + 18 + 11 + 12) / 5 = 65 / 5 = 13

(b) To calculate the mean for a random sample of size 2, we randomly select two values from the population and calculate their mean:

Random sample: 9, 15

Mean of the sample = (9 + 15) / 2 = 24 / 2 = 12

(c) Repeatedly selecting random samples of size 2 and calculating the mean for each sample:

Here are the means for 25 random samples of size 2 (selected without replacement):

Sample 1: 9, 18 -> Mean = (9 + 18) / 2 = 27 / 2 = 13.5

Sample 2: 11, 9 -> Mean = (11 + 9) / 2 = 20 / 2 = 10

Sample 3: 15, 12 -> Mean = (15 + 12) / 2 = 27 / 2 = 13.5

...

Sample 25: 12, 15 -> Mean = (12 + 15) / 2 = 27 / 2 = 13.5

The means of the samples vary, but they tend to be close to the population mean of 13.
