What does she pay in total premiums?
O$1239.00
O$1379.80
O $1551.60
O $1610.70
Answer: $1239.00
Step-by-step explanation:
I had to recheck on this.
For females that are ages 25-29, they have base auto insurance rate, meaning that the rate is set at 1. So multiply the base premium and base rate, 1239x1, and obviously it's the same 1239.
Hope this helped.

Consider the following graph, which details one bookstore’s sales over the course of one day, divided by genre.
A graph titled Book Sales by Genre has genre on the x-axis and Number sold on the y-axis. Romance, 52; horror, 55; Fantasy, 60; Biograph, 57; Humor, 58; Cookbook, 54.
By percent, how much greater do sales of horror books appear to be than sales of cookbooks? How much greater are they in reality?
The percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Given that:
Genre number sold
Romance 52Horror 55Fantasy 60Biography 57Humor 58Cookbook 54Let we have:
Number of horror books sold = P% greater than number of cookbooks sold
55 = P% greater than 54
55 = 54 + P% of 54
1 = P% of 54
[tex]1 = \dfrac{P}{100} \times 54\\\\P = \dfrac{100}{54} \approx 1.85[/tex]
Thus, the percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.

Every twentieth customer at a coffee shop gets a $5 gift card. Design a simulation for estimating the probability that a customer would need to visit the coffee shop at least 5 times to win a gift card.
The simulation of the customer visit is an illustration of probability
The probability that a customer would visit the coffee shop at least 5 times to win a gift card is [tex](\frac {11}{12})^{n} - (\frac n{12}) * (\frac {11}{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (\frac {11}{12})^{n - 4}[/tex]
How to design the simulation?From the question, we understand that every 12th customer gets a $5 gift card.
This means that the probability that a customer gets a gift card is:
p = 1/12
The probability that a customer would visit the coffee shop at least 5 times to win a gift card is calculated using the following complement rule:
P(x ≥ 5) = 1 - P(x <5)
The equation becomes
P(x ≥ 5) = 1 - P(0) - P(1) - P(2) - P(3) - P(4)
Using the binomial formula
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]
The equation becomes
[tex]P(x \ge 5) = ^nC_0 * (\frac 1{12})^0 * (1 - \frac 1{12})^{n - 0} - ^nC_1 * (\frac 1{12})^1 * (1 - \frac 1{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (1 - \frac 1{12})^{n - 4}[/tex]
Simplify
[tex]P(x \ge 5) = (\frac {11}{12})^{n} - (\frac n{12}) * (\frac {11}{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (\frac {11}{12})^{n - 4}[/tex]
Hence, the estimate that a customer would visit at least 5 times is [tex]P(x \ge 5) = (\frac {11}{12})^{n} - (\frac n{12}) * (\frac {11}{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (\frac {11}{12})^{n - 4}[/tex]

The figure below illustrates the market for steel. If the steel market is competitive, firms can produce steel at a constant marginal cost of $100 per ton. Therefore, the price of steel is $100 per ton, and 100 tons are produced. Assume that if all the steel companies consolidate into a monopoly, the monopoly’s marginal cost will fall to $70 per ton. Use the straight line tool to draw the monopoly’s marginal revenue and marginal cost lines (extend the marginal cost line to 300 tons). Then use the plot point tool to plot the monopoly’s profit-maximizing price and output on the demand curve.
If the market is controlled by a monopoly, total surplus is $____
The monopoly price will be given as 110 dollars per unit. Then the total surplus will be 4800 dollars.
How do determine the monopoly price and the total surplus?The figure below illustrates the market for steel.

The monopolist will maximize profit at MR = MC
150 - Q = 70

James spun the arrow 30 times which means 30 is the total. In other words, it's your denominator ([tex]\frac{x}{30}[/tex]). It landed on the blue section 12 times which means 12 is the part of the whole. In other words, it's your numerator ([tex]\frac{12}{y}[/tex]). Plug in the entire fraction and you get [tex]\frac{12}{30}[/tex]. Divide 12 by 30 and you get 0.4 or if you divide both the numerator & denominator by 6, you get [tex]\frac{2}{5}[/tex].

Manufacturers of tires report that tires should be able to last an average of 50,000 miles. A new tire company produces a different type of tread and tests 100 randomly selected tires. This sample of 100 tires lasted an average of 52,000 miles. Assuming the new type of tread does not improve the mileage of the tire, 200 sample means were simulated and displayed on the dotplot.
Using the dotplot and the sample mean mileage, is there convincing evidence that the new type of tread improves the mileage?
Yes, because a mean mileage of 52,000 or more occurred only 7 out of 200 times, the mean mileage is statistically significant. There is convincing evidence the new type of tire tread improves mileage of the tire.
Yes, because a mean mileage of 52,000 or less occurred 193 out of 200 times, the mean mileage is statistically significant. There is convincing evidence the new type of tire tread improves mileage of the tire.
No, because a mean mileage of 52,000 or less occurred 193 out of 200 times, the mean mileage is not statistically significant. There is not convincing evidence the new type of tire tread improves mileage of the tire.
No, because a mean mileage of 52,000 or more occurred 7 out of 200 times, the mean mileage is not statistically significant. There is not convincing evidence the new type of tire tread improves mileage of the tire.
The convincing evidence is Yes, because a mean mileage of 52,000 or more occurred only 7 out of 200 times, the mean mileage is statistically significant.

Find the area of the triangle.
Answer:
20 m²
Step-by-step explanation:
Formula (Area of triangle):
[tex]\text{A (Triangle)} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]
From the triangle, we can see that the base of the triangle is "7 + 3" m and the height of the triangle is "4" m.
[tex]\implies \text{A (Triangle)} = \dfrac{1}{2} \times (7 + 3) \times (4)[/tex]
Simplify the right-hand-side as needed to evaluate the area.
[tex]\implies \text{A (Triangle)} = \dfrac{1}{2} \times (10) \times (4)[/tex]
[tex]\implies \text{A (Triangle)} = \dfrac{40}{2} = 20 \ \text{m}^{2}[/tex]

8x+21+16x=25x+19 solve
Answer:
[tex]\Large\boxed{\sf{x=2}}[/tex]Step-by-step explanation:
GIVEN:
In order to solve this, you need to isolate the term x on one side of the equation.
8x+21+16x=25x+19First, combine like terms.
[tex]\Longrightarrow: \sf{8x+16x+21=25x+19}[/tex]
Solve.
8x+16x=24x
[tex]\Longrightarrow: \sf{24x+21=25x+19}[/tex]
You have to subtract by 21 from both sides.
[tex]\Longrightarrow: \sf{24x+21-21=25x+19-21}[/tex]
Solve.
[tex]\Longrightarrow: \sf{24x=25x-2}[/tex]
Subtract by 25x from both sides.
[tex]\Longrightarrow: \sf{24x-25x=25x-2-25x}[/tex]
Solve.
-x=-2
Then, you divide by -1 from both sides.

⇒ [tex]8x + 21 + 16x = 25x + 19[/tex]⇒ [tex]x(8 + 16) + 21 = 25x + 19[/tex]⇒ [tex]x(24) + 21 = 25x + 19[/tex]⇒ [tex]24x + 21 = 25x + 19[/tex]Now, rewrite 25x in such a way such that 24x can be repeated on both sides. Clearly, we can rewrite 25x as 24x + x. Then,
⇒ [tex]24x + 21 = \underline{25x} + 19[/tex]⇒ [tex]24x + 21 = \underline{24x + x} + 19[/tex]Since 24x is being repeated on both sides, we can cancel it.
⇒ [tex]\bold{24x} + 21 = \bold{24x} + x + 19[/tex]⇒ [tex]21 = x + 19[/tex]Finally, subtract 19 on both sides to isolate x.
