A doctor suspects you might have a certain strain of flu and wants to test your blood for the presence of markers for this strain of virus. Why would it be good for the doctor to take a sample of your blood rather than use the population? A.Testing all of the people in my city would be expensive and take too much time B.Testing all of the people in the hospital wouldn't tell them about my specific condition C.Testing all the blood in my body isn't really possible while keeping me alive

Answers

Answer 1
A, B, and C. all of them are reasonable choices and wouldn’t give any conclusion, because not everyone has the flu
Answer 2

Answer:

B. Testing all of the people in the hospital wouldn't tell them about my specific condition

Step-by-step explanation: As explained in the answer, the doctor suspects that you have a specific strain of flu, so it is not useful to test others because the suspected patient is already near. Also, you may be the first carrier of this strain of flu so the doctor would maybe want to focus on any changes found daily.

Angelo cuts a piece of wood for a project. The first cut is shown and can be represented by the equation y - 5x-1. The second cut needs to be parallel to the first. It will pass through the point (0,6). Identify the equation that
represents Angelo's second cut.

Answers

Answer:

The correct option is A

A) y = (1/5)x + 6

Step-by-step explanation:

The equation of the first cut shown in the graph is:

y = (1/5)x - 1

We know that a general form of linear equation is given as:

y = mx + c

Comparing both equations, we get that the slope m = 1/5

As the second cut is parallel to the first cut, it will have the same slope, that is m = 1/5

Substitute it in the general linear equation

y = mx + c

y = (1/5)x + c

We know that this equation passes through the point (0,6), substitute it in  the above equation>

6 = (1/5)(0) + c

c = 6

The equation for second cut be found by using m = 1/5 and c = 6

y = mx + c

y = (1/5)x + 6

Which relationships would most likely be causal? Select two options.

Answers

Answer:

A negative correlation between the temperature and the amount of snow still on the ground.

A negative correlation between the number of digital photos uploaded to a website and the amount of storage space that is left.

Step-by-step explanation:

These are the two relationships that are most likely to be causal. Causal relationships are those in which one aspect is the cause of the second one being described. Moreover, a negative correlation is one in which one aspect of the relationship increases while the other one decreases. In the first example, as the temperature goes up, this causes the amount of snow on the ground to go down. In the second example, as you upload more pictures to a website, there is less storage space.

A negative correlation between the temperature.

During the recent recession, Bob's home value dropped to only $175,000. Since then the economy has turned around and the market is improving at a rate of 4.5% annually. At this rate, how much will Bob's home be worth 12 years after the market started improving? And what equation did you use?

Answers

Answer:

Bob's home will worth $296,779.25 after 12 years.

Equation used is [tex]FV = $175,000( 1 + 4.5/100)^(12)\\[/tex]

Step-by-step explanation:

Current value of Bob's house =[tex]FV = $175,000( 1 + 4.5/100)^12\\FV = $175,000( (100+ 4.5)/100)^12\\FV = $175,000( (104.5)/100)^12\\FV = $296,779.25[/tex]

market is improving at 4.5% annually.

This, means that the value of house gets appreciated by 4.5% each year from its previous year value.

This is a problem of compound interest formula

[tex]FV = PV(1+r/100)^n[/tex]

where PV is the present value of any thing

FV is the future value

r is the annual rate of interest

t is the time in number of year for which rate is applicable.

_____________________________________

Given

PV = $175,000.

r = 4.5%

t = 12 years

Value after 12 year will be given by

[tex]FV = $175,000( 1 + 4.5/100)^(12)\\FV = $175,000( (100+ 4.5)/100)^(12)\\FV = $175,000( (104.5)/100)^(12)\\FV = $296,779.25[/tex]

Thus, Bob's home will worth $296,779.25 after 12 years.

Equation used is [tex]FV = $175,000( 1 + 4.5/100)^(12)\\[/tex]

four equal circles are made with four corners of a square of side 7cm as their centers.The radius of each circle is 3.5cm
Calculate the area of the circular portions outside the square.​

Answers

Answer: 147π/4

Step-by-step explanation:

Area of one circle = π*r^2

r = 3.5 cm =7/2 cm

area = π*7/2*7/2 = 49π/4

therefore area of 4 circles =49π

As 1/4th circle is removed from each circle the shaded area = 3/4 area of the area of the circle.

therefore, the are of the shaded portion = 49π*3/4 = 147π/4

Step-by-step explanation:

Move all terms not containing  y  to the right side of the equation.

Add  226  to both sides of the equation.

y/23=−207+226

Add  −207  and  226.

y/23=19

Simplify both sides of the equation.

Cancel the common factor of  23.

The maximum capacity in the
gymnasium is 1200 people. There are
180 students performing for the
assembly. If each class has 30 students,
how many classes can fit in the gym to
watch the performance? (2.4)

Answers

Answer:

34 classes

Step-by-step explanation:

First, subract 180 from 1200. You should get 1020. then do 1020/30. So 34 classes can watch the performance of 180 students.

Answer:

34

Step-by-step explanation:

If there are 180 students performing you need to subtract that from 1200, which leaves you with 1020

Then you divide it by 30, since there are 30 people in each class

You should then end up with 34 classes

Step-by-step explanation:

For a quadratic equation, the vertex form is given by : [tex]y=a(x-h)^2+k[/tex], where (h, k) is the vertex.

The given quadratic equation: [tex]x^2 + 20x + 28 = 9[/tex]

b= 20

[tex]x^2+20+100+19=-100[/tex]   [(b/2)²=20/2=10]

In △EKL, m∠K = 90º, m∠E = 25º, EK = 3 cm, KH - altitude. Find EH.

Answers

Answer:

EH = 3.31

Step-by-step explanation:

We have been given a right angle triangle EKL. As KH has been given as the altitude (perpendicular) of the right angled triangle, and K is the right angle, we can say that EK is tthe base of the triangle and EH is the only side lleft, which is the hypotenuse of the triangle.

Where,

EK = Base = 3

KH = perpendicular altitude

EH = Hypotenuse

m<K = 90

m<E = 25

We know that

cosθ = Base/ Hypotenuse

cos 25 = 3/ EH

EH = 3/cos25

EH = 3.31

Perpendicular alitutude can also be calculated by using the formula for tanθ.

Given that it has already taken 20 minutes, what is the probability that the wait time will be more than an additional 23 minutes? Round your answer to three decimal places.

Answers

Answer:

0.298

Step-by-step explanation:

in this case we have an exponential distribution:

1 - e ^ (- x / y)

where x and y corresponds to the times we find in the exercise.

Now follows memoryless property.

P (More than 23 additional minutes | 20 minutes passed)

P = P (More than 23 minutes)

P = 1 - P (Less than or equal to 23 minutes)

P = 1 - (1 - e ^ (- 23/19))

P = 0.298

Therefore the probability is 29.8%

Find the indicated values, where g(t) = t^2 - t and f(x) = 1 + x g(f(3)-2f(1))

Answers

Answer:

B. 0

Step-by-step explanation:

Given

g(t) = t² - t

f(x) = 1 + x

Required

Find g(f(3) - 2f(1))

First, we'll solve for f(3)

Given that f(x) = 1 + x

f(3) = 1 + 3

f(3) = 4

Then, we'll solve for 2f(1)

2f(1) = 2 * f(1)

2f(1) = 2 * (1 + 1)

2f(1) = 2 * 2

2f(1) = 4

Substitute the values of f(3) and 2f(1) in g(f(3) - 2f(1))

g(f(3) - 2f(1)) = g(4 - 4)

g(f(3) - 2f(1)) = g(0)

Now, we'll solve for g(0)

Given that g(t) = t² - t

g(0) = 0² - 0

g(0) = 0 - 0

g(0) = 0

Hence, g(f(3) - 2f(1)) = 0

From the list of given options, the correct answer is B. 0

Answers

Answer:

A) ∠9 = ∠10 = ∠11 = ∠12  = 90°

∠2 = ∠3 = ∠5 = ∠8 = 135°

∠1 = ∠4 = ∠6 = ∠7 = 45°

B) 1. ∠4 and ∠1 -> vertical angles

2. ∠7 and ∠5 -> supplementary

3. ∠9 and ∠10 -> supplementary

Step-by-step explanation:

Data

∠4 = 45°∠5 = 135°∠10 = ∠11

The following are vertical angles, so they are congruent:

∠1 ≅ ∠4

∠3 ≅ ∠2

∠11 ≅ ∠9

∠10 ≅ ∠12

∠7 ≅ ∠6

∠5 ≅ ∠8

From here and data, it is deduced that

∠11 ≅ ∠9 ≅ ∠10 ≅ ∠12

From the picture, the addition of them is equal to 360°, then:

∠11 + ∠9 + ∠10 + ∠12 = 360°

4*∠11 = 360°

∠11 = 360°/4

∠11 = 90° = ∠10 = ∠9 = ∠12

∠2 and ∠4 are supplementary, then:

∠2 + ∠4 = 180°

∠2 = 180° - 45°

∠2 = 135°

∠7 and ∠5 are supplementary, then:

∠7 + ∠5 = 180°

∠7 = 180° - 135°

∠7 = 45°
