Suppose 50% of the people in a particular population have high blood pressure. Of the people with high blood pressure, suppose 75% smoke; whereas, only 50% of the people without high blood pressure actually smoke. What percent of people who smoke have high blood pressure

Answers

Answer:

37.50%

Step-by-step explanation:

The computation of the percentage of people who smoke have high blood pressure is shown below:

Given that

There is 50% of the people who has the high blood pressure

And, out of which 75% would smoke

So, the percent of the people who smoke have high high blood pressure is

= 50% × 0.75

= 37.50%

If f(1) = 2 and f(n+1) = f(n)^2 – 3 then find the value of f(3).

Answers

Answer:

The value of f(3) is -2.

Step-by-step explanation:

This is a recursive function. So

[tex]f(1) = 2[/tex]

Now, we find f(2) in function of f(1). So

[tex]f(1+1) = f(1)^2 - 3[/tex]

[tex]f(2) = f(1)^2 - 3 = 2^2 - 3 = 1[/tex]

Now, with f(2), we can find the value of f(3).

[tex]f(2+1) = f(2)^2 - 3[/tex]

[tex]f(3) = f(2)^2 - 3 = 1^2 - 3 = -2[/tex]

The value of f(3) is -2.

What is the equation of a line, in general form, that passes through point (1,-2) and has a siope of 1/3?

Answers

9514 1404 393

Answer:

x -3y -7 = 0

Step-by-step explanation:

The general form of the equation for a line is ...

ax +by +c = 0

where a, b, c are mutually prime and the leading coefficient is greater than zero.

The general form equation for a line with slope m = rise/run through point (h, k) can be found by simplifying ...

rise(x -h) -run(y -k) = 0 . . . . where run has the sign of the slope

For the given point and slope, we have ...

1(x -1) -3(y -(-2)) = 0

x -3y -7 = 0

A natural number is a number that you would use to count kids in a class for example. Like, 1,2,3,4 and so on. 2.5 is not a natural number since there cant be 2.5 of a student. 5-151 is a negative number and there cant be negative students. -13+51=38. 38 is a natural number.

Answer:

38.2°

Step-by-step explanation:

The law of sines tells you ...

sin(x)/15 = sin(27°)/11

sin(x) = (15/11)sin(27°) . . . . . multiply by 15

x = arcsin((15/11)sin(27°)) ≈ arcsin(0.619078) ≈ 38.2488°

x ≈ 38.2°

_____

Additional comment

In "law of sines" problems, you need to identify a side and opposite angle that you know both values of. Then, you need to identify whether you're looking for an angle or a side, and whether its opposite side or angle is known. If two angles are known, you can always figure the third from the sum of angles in a triangle.

Here, we have angle 27° opposite side 11. We are looking for an angle, and we know its opposite side. This lets us use the ratio formula directly. Since the angle is the unknown, it is useful to write the equation with sines on top and sides on the bottom.

The given angle is opposite the shorter of the given sides, so this triangle has two solutions. We assume that we want the solution that is an acute angle (141.8° is the other solution). That assumption is based on the drawing. Usually, you're cautioned not to take the drawings at face value.

If the value of a quarter of a kilogram is ₹ 40, how much money will be the value of 100 grams?

Answers

Answer:

₹16

Step-by-step explanation:

1/4 kg = ₹ 40

1kg = 40×4 = ₹160

1000g = 1kg

100g = 100/1000 kg

= 0.1kg

0.1kg= 0.1×160 = ₹16

First convert 40 grams to kg. A kilogram is 1000 grams, so you divide 40 by 1000 which is .04 kg.

40 grams * 1 kg / 1000 grams = .04 kg

(Note here that 1 kg = 1000 grams meaning that 1 kg / 1000 grams = 1; anything divided by itself is one; therefore, when I multiply by 1 kg / 1000 grams I’m not changing the value, only the units.)

Then you simply multiply the price per kg by the number of kg giving 6.6.

.04 kg * 165 / 1 kg = 6.6

(Oranges are different. You can’t compare apples to oranges.)

Review: Jen sells flowers. She charges $2 per flower plug a $3 flat delivery fee. How many flowers did she deliver if she made $21?

Answers

Answer:

she delivers 9 flower plugs.

Step-by-step explanation:

in a standard equation the equation would be 21 = 2x + 3 and if you isolate the x you would have to first subtract the 3 from both sides and that would leave you with 18 = 2x and then you have to divide both sides by 2 and get 9=x

Answers

Step-by-step explanation:

√3sinA-cosA=√2

dividing both side by (√3²-1²=2 we get)

√3/2 sinA-1/2.cos A=√2/2

cos 30sinA-sin30cosA=√2/(√2×√2)

sinAcos30-cosAsin30=1/√2

sin(A-30)=sin45,sin(180-45)

therefore

A-30=45,135

A=45+30=75 or A=135+30=165

The table shows the fees to park in a parking lot.

second hour = $1.50
each additional hour or part of an hour = $2.
How much does it cost to park for 4 1/2 hours?

Answers

Answer:

$7.50

Step-by-step explanation:

4 1/2 hours total

1st hour = $1.00 ; 3 1/2 hrs remaining

2nd hour = $1.50 ; 2 1/2 hrs remaining

after 2 hours you pay $2 per hour so 2.5 x 2 = $5.00

What is the y-intercept of the line given by the equation y = 8x + 75?
A. (0,75)
B. (0,-8)
C. (0, -75)
D. (0,8)

Answers

Answer:

The answer is A.

Step-by-step explanation:

In a linear equation, y = mx + b where b represent y-intercept.

y-intercept is the point where it touches y-axis, so the value of x is 0.

The y-intercept of the given equation is (0, 75). Therefore, option A is the correct answer.

What is a y-intercept?

In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

The given equation of a line is y=8x+75.

To find the y-intercept, set x = 0 and solve for y.

Here, substitute x=0 in y=8x+75, we get

y=8(0)+75

y=75

So, the y-intercept is (0, 75)

Therefore, option A is the correct answer.

A subscription allows consumer in over 190 countries to stream television programmes and films through the internetIn 2016 Netflix decided to increase the price of its standard UK subscription from 5.99 to 7.49 per month. This move reflected Netflix's shift toward producing more of its own original streaming content, such as the hit drama 'Stranger Things', rather than repeating shows that are available on terrestrial channels such as BBC1 or itv1.In recent years, the online streaming market has become increasingly competitive with rivals such as Amazon Prime, investing $180 million on 36 episodes of 'The Grand Tour'. To keep up, Netflix has commited itself to spending $6bn on new, original programming in 2017.Netflix faces the difficult of raising prices to fund new shows, whilst at the sime time not putting off new and existing subscribers.
