It is well known that steroid usage is banned in athletes. As a result, athletes are randomly tested. The steroid test procedures are believed to be equally effective on both steroid users as well as non-steroid users. The effective rate is 98%. Assume 90% of the athletes are clean (not steroid users). Suppose an athlete is tested as a steroid user (and thus could be disqualified from the Summer Olympics games), what is the probability that the athlete is actually clean (i.e., not a steroid user)
Answers
Answer:
18% that the athlete is disqualified but is actually clean
Step-by-step explanation:
In order to find the probability of two events happening together, in this case the athlete being disqualified and being clean, we need to multiply the probabilities. So,
It is a 90% chance that the athlete is clean and a 2% chance that the test fails so multiply the two
.9 * .2 = .18
This means that it is an 18% chance that the athlete is clean but is still disqualified.

. A box is on a table.
The area of the box in contact with the table is 1500 cm².
The pressure on the table is 28 newtons/m².
Work out the force exerted by the box on the table.
Give your answer correct to the nearest whole number.
Answers
Answer: We know that force = pressure * area
Step-by-step explanation:
Given that,
Pressure on the table = 28 Newton/m^2
Area of the box in contact with the table = 1500 cm^2
= 1500/100*100 m^2
= 0.15 m^2
Therefore, as per the formula of force;
Force exerted by the box = 28 Newton/m^2 * 0.15 m^2
= 4.2 Newton
So, force exerted by the box is approximately equal to 4 Newton.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that:
Number of used cars on Monday = 22Number of cars on Tuesday = 18Now,
Let's call the total number of cars sold during the week "x".
We know that the number of cars sold on Monday and Tuesday is 25% of the total number of cars sold during the week. So we can write:
\(\sf 22 + 18 = 0.25x\)
Simplifying, we get:
\(\sf 40 = 0.25x\)
Dividing both sides by 0.25, we get:
\(\bold{x = 160}\)
Hence, by the unitary method the answer will be 160.

A population numbers 12,000 organisms initially and grows by 17.5% each year. The growth function of the population is P = 12,000 x 1.175^t
An exponential growth function can be written as:
P = A (1 + r)ⁿ
Where:
P = quantity after n periods
n = number of periods
r = growth rate per period
A = initial quantity
In the given problem, the period is the number of years t
A = 12,000
r = 17.5% = 0.175

In ΔHIJ, h = 33 cm, i = 61 cm and j=39 cm. Find the area of ΔHIJ to the nearest square centimeter.
Answers
Thus, the area of ΔHIJ using the Heron's formula is found as 580.47 square centimeter.
Explain about the Heron's formula:Heron of Alexandria (c. 62 ce) is credited with developing the Heron's formula, which determines the area of a triangle in regards of the lengths of its sides. If the side lengths are represented by the symbols a, b, and c: √s(s - a)(s - b)(s - c)
where s = half the perimeter,
s = (a + b + c)/2.
given data:
In ΔHIJ,
h = 33 cm, i = 61 cm and j =39 cm.semi -perimeter s = (i + j + h) / 2
s = (33 + 61 + 39) / 2
s = 66.5
Now,
s - h = 66.5 - 33 = 33.5
s - i = 66.5 - 61 = 5.5
s - j = 66.5 - 39 = 27.5
area of ΔHIJ = √s(s - h)(s - i)(s - j)
area of ΔHIJ = √66.5*33.5*5.5*27.5
area of ΔHIJ = √336947.1875
area of ΔHIJ = 580.47
Thus, the area of ΔHIJ using the Heron's formula is found as 580.47 square centimeter.

C) x = -7 or 1
D) non of above
Answers
Answer:
The roots of the quadratic equation x² + 4x + 7 = 0 can be found using the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a
In this case, a = 1, b = 4, and c = 7. Substituting these values into the formula, we get:
x = (-4 ± √(4² - 4(1)(7))) / 2(1)
x = (-4 ± √(16 - 28)) / 2
x = (-4 ± √(-12)) / 2
x = (-4 ± 2i√3) / 2
x = -2 ± i√3
Therefore, the roots of the equation x² + 4x + 7 = 0 are: A) 2 + i√3 or 2 - i√3.

On January 1, 20x1, Entity A acquires 25% interest in Entity B for
₱800,000. Entity B reports profit of ₱1,000,000 and declares dividends of ₱100,000 in 20x1. How much is the carrying amount of the investment in associate on December 31, 20x1?
Answers
In this case, Entity A acquired a 25% interest in Entity B for ₱800,000 on January 1, 20x1. This means that the initial carrying amount of the investment was ₱800,000.
Entity B reported a profit of ₱1,000,000 in 20x1. Since Entity A has a 25% interest in Entity B, its share of the profit is ₱250,000 (25% x ₱1,000,000).
Entity B also declared dividends of ₱100,000 in 20x1. Since Entity A has a 25% interest in Entity B, its share of the dividends is ₱25,000 (25% x ₱100,000).
To calculate the carrying amount of the investment in associate on December 31, 20x1, we need to subtract Entity A's share of the dividends from its share of the investee's profits and add this amount to the initial carrying amount of the investment:
Carrying amount of investment = Initial carrying amount + Share of profit - Share of dividends
Carrying amount of investment = ₱800,000 + ₱250,000 - ₱25,000
Carrying amount of investment = ₱1,025,000
Therefore, the carrying amount of the investment in associate on December 31, 20x1, is ₱1,025,000.

En una ciudad de 5000 habitantes, la tasa diaria
de infección con un virus de la gripe varia directamente con el producto de
personas infectadas y el número de personas no infectadas. Cuando se han
infectado 1000 personas, la gripe se esparce a razón de 40 nuevos casos por día.
¿Para qué número de personas infectadas, la tasa diaria de infección es la
máxima?
Answers
According to the information, the maximum infection rate is: k * 2500 * (5000 - 2500) = 6250k = 40
How to calculate for what number of infected people, the daily infection rate is the maximum?To address this problem, we can use the law of the infection rate, which states that the infection rate is directly proportional to the product of the number of people infected and the number of people not infected. Therefore, we can write:
infection rate = k * (infected people) * (uninfected people)where "k" is a constant of proportionality. Since we want to find the number of people infected that produces the maximum infection rate, we can consider the infection rate as a function of the variable "x" representing the number of people infected. Therefore, we can write:
infection rate = k * x * (5000 - x)To find the value of "x" that maximizes the infection rate, we can derive this function and set the derivative equal to zero:
d(infection rate)/dx = k * (5000 - 2x) = 0This implies that 5000 - 2x = 0, and therefore:
x = 2500Therefore, the number of infected people that produces the maximum daily rate of infection is 2,500.
However, we must verify that this result is consistent with the information given in the problem. We know that when there are 1,000 people infected, the flu spreads at the rate of 40 new cases per day. Therefore, if we add 1,500 more infected people (for a total of 2,500), the infection rate would be:
infection rate = k * 2500 * (5000 - 2500) = 6250kIf the infection rate is 40 new cases per day, we have:
40 = 6250kwhich implies that:
k = 0.0064Therefore, the maximum infection rate is:
maximum infection rate = k * 2500 * (5000 - 2500) = 6250k = 40Learn more about infection in: https://brainly.com/question/29850356

The coordinates of the vertices for the image is A′(−3, 6), B′(0, 10), C′(−3, 3).
The vertices of the preimage triangle ABC are given as A(-3,3), B(0,7), and C(-3,0). To translate the preimage 3 units up, we need to add 3 to the y-coordinate of each vertex. Therefore, the vertices of the image triangle A'B'C' will be A'(-3,6), B'(0,10), and C'(-3,3). Thus, option B, A′(−3, 6), B′(0, 10), C′(−3, 3), is the correct answer.

Hatif has $150 in his account. He saves $80 each month. How long will it take before he has $630 in his account?
Answers
Answer:
6 months
Step-by-step explanation:
We can set up an equation based on his monthly savings to find out how long it will take for Hatif to reach $630 in his account.
Let's assume it takes Hatif "n" months to reach $630 in his account. Each month, he saves $80.
The equation representing the situation is:
$150 + $80n = $630
Now, let's solve for "n":
$80n = $630 - $150
$80n = $480
n = $480 / $80
n = 6
Therefore, it will take Hatif 6 months to reach $630 in his account.
