Answer:

5216.844

Step-by-step explanation:

Let x be the fourth number.

We know that the sum of the four numbers is 20500:

2341.578 + 10690 + x + 2341.578 = 20500

Simplifying and solving for x:

x = 20500 - 2341.578 - 10690 - 2341.578

x = 5216.844

Answer:

Step-by-step explanation:

When x = -4, y = 2(-4)+2 = -6.

When x = -3, y = 2(-3)+2 = -4.

Fill in the other values of y the same way.

Answer:

Explanation:

y = 2(-4) + 2

y = -6

y = 2(-3) + 2

y = -4

y = 2(-2) + 2

y = -2

y = 2(-1) + 2

y = 0

y = 2(0) + 2

y = 2

y = 2(1) + 2

y = 4

y = 2(2) + 2

y = 6

Answer:

82.45

Step-by-step explanation:

The price of the purse is 75.99 and tax is 8.5%

Tax = price  time tax rate

Answer:

do 27/3...............

the temperature at 9 P.M. is 38 degrees Fahrenheit, and the equation that represents this temperature is T(9) = 53 - 3(9-4).

How to determine the temperature ?

To determine the temperature at 9 P.M., we need to calculate how much the temperature drops from 4 P.M. to 9 P.M. We know that the temperature drops 3 degrees per hour, and since there are 5 hours between 4 P.M. and 9 P.M., the temperature will have dropped 3 x 5 = 15 degrees.

Therefore, to calculate the temperature at 9 P.M., we need to subtract 15 degrees from the temperature at 4 P.M.:

Temperature at 9 P.M. = Temperature at 4 P.M. - 15

Substituting the given temperature of 53 degrees Fahrenheit at 4 P.M.:

Temperature at 9 P.M. = 53 - 15 = 38 degrees Fahrenheit

Thus, the equation that accurately represents the temperature at 9 P.M. is:

T(9) = 53 - 3(9-4)

Simplifying the equation:

T(9) = 53 - 15

T(9) = 38

In conclusion, the temperature at 9 P.M. is 38 degrees Fahrenheit, and the equation that represents this temperature is T(9) = 53 - 3(9-4).

The correct options regarding the statistical measures in this problem are given as follows:

3. The IQR remains a 2.

7. Mean 84º.

To find the quartiles, we need to consider the median, which is the middle value of a data-set, hence:

For question 3, adding the shoe size of 8, the ordered data-set is given by:

5, 5.5, 6, 6.5, 6.5, 7, 7.5, 8, 8, 8, 8.5.

Hence:

Hence the IQR is given by:

IQR = 8 - 6 = 2.

Thus the correct option is:

The IQR remains a 2.

For question 7, the second lowest value would remain the second highest value. The only measure that considers all the values to be calculated is the mean, hence the correct option is:

Answer:

D(30,60)

Step-by-step explanation:

It was way outside the other points that are around the line.

The point (30,60) is a high leverage point on the regression plot.

High leverage points are those that are extreme but follow the regression equation's trend.

High leverage points are distinct from outliers, which deviate from the graph's or plot's pattern or trend.

Looking closely at the regression plot, the coordinate (30,60) follows the trend of the plot, however, it is farther from the majority of the points on the graph.

Hence, the point (30,60) is a high leverage point on the regression plot.

Step-by-step explanation:

The SS Error refers to the sum of the squares of the deviations of the observations, from their mean. It is simply the total variance from the observations on the study.

In performing a one-way ANOVA, the SS Error measures the variability of the observed values around their respective means and this is done through the summation of the squared differences between each observed value of the response and its corresponding treatment mean.

Expanding and simplifying the expression gives:

(3x - 2)² = 9x² - 12x + 4

Here we want to expand and simplify the expression below:

(3x - 2)²

First let's expand that, we can rewrite this as:

(3x - 2)² = (3x - 2)*(3x - 2)

We can distribute that product to get:

(3x - 2)*(3x - 2) = (3x)*(3x) + (3x)*(-2) + (-2)*(3x) + (-2)*(-2)

Now we can keep simplifying this to get:

(3x)*(3x) + (3x)*(-2) + (-2)*(3x) + (-2)*(-2) = 9x² - 6x - 6x + 4

9x² - 6x - 6x + 4 = 9x² - 12x + 4

The simplified expression is:

The product of the expression 7 x 63 is 441.

We have,

To find the product of 7 x 63 using the distributive property, we can break down 63 as the sum of its factors, such as 60 and 3:

7 x 63 = 7 x (60 + 3)

Answer:

11.46 meters

Step-by-step explanation:

12min 30sec = 12.5min

55km/h * 12.5min * 1h/60min = 11.4583333333meters

The value of the expression \(2(cos^4 60 + sin^4 30) -(tan^2 60 + cot^2 45) + 3\times sec^2 30 is 33/4.\)

Let's simplify the expression step by step:

Recall the values of trigonometric functions for common angles:

cos(60°) = 1/2

sin(30°) = 1/2

tan(60°) = √(3)

cot(45°) = 1

sec(30°) = 2

Substitute the values into the expression:

\(2(cos^4 60 + sin^4 30) - (tan^2 60 + cot^2 45) + 3sec^2 30\)

= \(2((1/2)^4 + (1/2)^4) - (\sqrt{(3)^2 + 1^2} ) + 3(2^2)\)

= 2(1/16 + 1/16) - (3 + 1) + 3*4

= 2(1/8) - 4 + 12

= 1/4 - 4 + 12

= -15/4 + 12

= -15/4 + 48/4

= 33/4

Therefore, the value of the expression \(2(cos^4 60 + sin^4 30) -(tan^2 60 + cot^2 45) + 3\times sec^2 30 is 33/4.\)

Answer:

Step-by-step explanation:

5 years than 3 times can be represented as 5*3.

5*3=15.

If Eva is 2, and Bill is 15 years older, 2+15=17.

Therefore, Bill is 17 years of age.

Answer:

\(\displaystyle 4.\overline{15} = \frac{137}{33}\).

Step-by-step explanation:

Start by separating this decimal number into its integer part and its fraction part:

\(4.151515\cdots = 4 + 0.151515\cdots\)

The most challenging task here is to express \(0.151515\cdots\) as a proper fraction. Once that fraction is found, expressing the original number \(4.151515\cdots\) will be as simple as rewriting a mixed number as an improper fraction.

Let \(x = 0.151515\cdots\). \((x + 4)\) would then represent the original number.

Note that the repeating digits appear in groups of two. Therefore, if the digits in \(x\) are shifted to the left by two places, the repeating part will continue to match:

\(\begin{aligned}x = 0.&151515\cdots && \\ 100\, x = 15.& 151515\cdots \end{aligned}\).

Note, that this "shifting" is as simple as multiplying the initial number by \(100\) (same as \(10\) raised to the power of the number of digits that needs to be shifted.)

Subtract the original number from the shifted number to eliminate the fraction part completely:

\(\begin{aligned}&(100\, x) - x \\ &= 15.151515\cdots\\ & \phantom{=}- 0.151515\cdots\\&=15 \end{aligned}\).

In other words:

\(99\, x = 15\).

\(\displaystyle x = \frac{15}{99} = \frac{5}{33}\).

Therefore, the original number would be:

\(\displaystyle x + 4 = \frac{5}{33} = \frac{132 + 5}{33} = \frac{137}{33}\).
