Answers
The decrease on the value of stock is found to be 80 dollars and the second option is correct option
What is decrease on value of stock?The decrease on value of stock refers to reduction from the original value of the stock.
From the question we have that:
value of a stock decreases by an average of 10 dollars each week
This means that each week 10 dollars is subtracted from the value of the stock
How to find the total average decrease in the stock after 8 weeksif the stock reduces 10 dollars every week this is written mathematically as
1 week = 10 dollars
8 weeks = ?
cross multiplying gives
1 week * ? = 8 weeks * 10 dollars
? = 80 dollars
The unknown variable represented as ? is calculated to be 80 dollars
Hence multiplying the number of weeks by the amount reduced per week gives the decrease in stock and option b has modulus of 10 and the correct option

Answers
We are given a graph of the height of a falcon with respect to time. The x-intercept of the graph represents the height of the falcon when x = 0, that is, the initial height. since the graph shows that the x-intercept is 8, this means that the falcon starts 8 feet in the air.
A store owner buysy scooter for $40.99 and sells it for $94. What is the percent of increase for the price of the scooter? Round to the nearest tenth if necessary.
Answers
Percentage increase in the price of scooter = 129.3%
What is percentage?The word "percentage" refers to a figure that is stated as a percentage of 100, a relative value that denotes hundredths of any amount. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
For example 2% means [tex]\frac{2}{100}[/tex]. Here 2 is expressed as a fraction of 100.
Cost price of scooter = $40.99
Selling price of scooter = $94
Increase in price of the scooter = $(94 - 40.99)
= $53.01
Percentage increase in the price of scooter = [tex]\frac{53.01}{40.99}\times 100[/tex]
= 129.3%

The ratios of the lengths of the correspondingsides are equal because the triangles havethree pairs of congruent angles.havedo not have
Answers
If one triangle is the dilation of the other triangle, then they are similar
The addition of the angles in a triangle is equal to 180°
Triangle XYZ has angles measuring 53° and 23º, then the third angle measure:
53° + 23° + x = 180°
x = 180° - 53° - 23°
x = 104
AA similarity postulate states that If two angles in one triangle are congruent to two angles in another triangle, the two triangles are similar
In this case, the two triangles have only one angle in common, then the AA postulate is not satisfied, and the triangles are not similar nor dilated.
Triangle X'Y'Z' is not a dilation of Triangle XYZ. The ratios of the lengths of the corresponding sides are not equal because the triangles do not have three pairs of congruent angles.

In addition, there is a 10.2% probability that arandomly selected person aged 20 years or older is male, given that he or she jogs. What is the probability that a randomly selected person aged 20years or older is male and jogs? Would it be unusual to randomly select a person aged 20 years or older who is male and jogs?The probability that a randomly selected person aged 20 years or older is male and jogs is(Round to three decimal places as needed.)
Answers
Answer:
P(J∩M) = 0.027
Explanation:
Let's call J the event that a selected person aged 20 years or older is a jogger and M the event that a selected person aged 20 years or older is male.
Then, the probability P(J∩M) that a randomly selected person aged 20
years or older is male and jogs can be calculated as:
P(J∩M) = P(J) * P(M|J)
Where P(J) is the probability that a selected person aged 20 years or older is a jogger and P(M|J) is the probability that hat a selected person aged 20 years or older is male given that he or she jogs.
So, replacing P(J) by 26.2% and P(M|J) by 10.2%, we get:
P(J∩M) = 0.262 * 0.102
P(J∩M) = 0.027
P(J∩M) = 2.7%
Therefore, the probability that a randomly selected person aged 20 years or older is male and jogs is 0.027

Owners of a recreation area are filling a small pond with water. They are adding water at a rate of 26 liters per minute. There are 600 liters in the pond to start.
Let W represent the total amount of water in the pond (in liters), and let I represent the total number of minutes that water has been added. Write an equation
relating I to T. Then use this equation to find the total amount of water after 19 minutes
Answers
The equation for the conditions given in the question can be written as: W = 600 + (26)I and the total amount of water after 19 minute is 1094.
What is an equation?
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.
As given in the question,
The amount of the water at the beginning is 600 liters.
And the rate of water being added is 26 liters per minute.
Let I be the number of minutes. So, the amount of water added in I minute is 26I.
Adding the initial amount and the amount of water after I minute. We get the equation as:
W = 600 + (26)I
Here, W represents the total amount of water in the pond.
Putting the value of I as 19 in the above equation.
W = 600 + (26)(19)
W = 600 + 494
W = 1094
Hence, the total amount of water after 19 minute is 1094 liters.

A linear equation that models the price-sales relationship for this toy is y = -500x + 5000
In this question, we need to find a linear equation that models the price-sales relationship for this toy.
We have been given that the line passes through (6, 2000) and (8, 1000)
Using the formula for the two-point form of equation of line,
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - 2000)/(1000 - 2000) = (x - 6)/(8 - 6)
(y - 2000)/(-1000) = (x - 6)/2
2(y - 2000) = -1000(x - 6)
y - 2000 = -500(x - 6)
y = -500x + 3000 + 2000
y = -500x + 5000
Therefore, a linear equation that models the price-sales relationship for this toy is y = -500x + 5000

Answers
Percent of the scores are less than 19 is 45.4%.

A data set with a normal distribution has the majority of its values clustered in the middle of the range, while the remainder taper off symmetrically toward either extreme.
(a) μ = 19.6, σ = 5.2
First, find the z-score.
z = (x − μ) / σ
z = (19 − 19.6) / 5.2
z = -0.115
To calculate the probability, use a chart or calculator.
P(Z < -0.115) = 0.454
45.4 % of the scores are under 19.
(b) First, find the z-score.
z = (x − μ) / σ
z = (21 − 19.6) / 5.2
z = 0.269
To calculate the probability, use a chart or calculator.
P(Z > 0.269) = 1 − P(Z < 0.269)
P(Z > 0.269) = 1 − 0.606
P(Z > 0.269) = 0.394
