Andy made a spirometer for a physics experiment. The spirometer is designed to measure the volume of air in a person's lungs. Andy found that when he breathes normally, he inhales and exhales 0.5 of a liter of air per breath. He also found that when breathing normally, after exhaling, he still has 2 liters of air in his lungs.

Andy recorded 15 breaths in one minute, starting at the beginning of an exhale.

If Andy inhaled and exhaled the exact same amount of air in each breath, which of the following functions best models the amount of air in Andy's lungs t seconds after he started recording?

Answer:

Step-by-step explanation:

Let x be the random variable representing the length of an oarfish. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

The given probability value is 16% = 0.16. From the normal distribution table, the z score corresponding to the probability value is - 0.99

This indicates that the sample mean is lower than the population mean

Therefore,

- 0.99 = (x - 6.5)/1.5

- 0.99 × 1.5 = x - 6.5

- 1.5 = x - 6.5

x = - 1.5 + 6.5

x = 5m

The correct answer is

oarfish that are shorter than 5 m

Answer:

oarfish that are shorter than 5

oarfish that are longer than 8 m

Step-by-step explanation:

A crate containing 16 bags of powdered milk weighs of 63.2 lbs.

The weight of the empty crate is 2.4 lbs

The weight of the milk by itself is the difference of full and empty crate 63.2 - 2.4 = 60.8

To find  the weight of one bag of powdered milk divide 60.8 by 16 = 3.8 lb

Answer:

0.03

Step-by-step explanation:

Given data

Probability that it will rain on Sunday= 0.7

Probability that it will rain on Monday = 0.2

Firstly we need to solve for the probability that it will rain on Tuesday

Sample space S = number of week days = 7

Probability that I will rain on Tuesday = 1/7= 0.14

Hence the probability that it rains on BOTH Monday and Tuesday= 0.2*0.14= 0.028

Rounding up the nearest hundredths = 0.03

Answer:

The value of x is 2

Step-by-step explanation:

Diameter = 2r -------------------------------------------------------------------(1)

where r is the radius

The value of the diameter = 32 m   and  radius is given to be 4(x+2)

substitute the above into equation (1)   and then solve for x

32  =  2 [ 4(x + 2)]

first open the inner bracket

32 = 2[4x + 8}

then open the outer bracket

32 = 8x + 16

subtract 16 from both-side of the equation

32 - 16 = 8x +16 - 16

16 = 8x

Divide both-side of the equation by 8

16/8  = 8x/8

2 = x

x = 2

Therefore, the value of x is 2

Answer:

Since its a right triangle you automatically know the C is 90 degrees. And since all triangle have to add up to 180 degrees, you know B has to equal 40 degrees.

A= 50

B= 40

C= 90

B + C

40 + 90

BC = 130 degrees

Awesome construction

Step-by-step explanation:

Marsha is building the construction pictured with a straightedge and compass. Marsha is building a line through P that is perpendicular to the line​. Thus, option (d) is correct.

What is construction?

The term construction refers to constructed the lines. It was the creation of an abstract entity. It was the mainly used in the math, art, and science. It was the accurate form of the lines in geometry, angles, and the drawings of shapes. It used the ruler and the compasses.

According to the Marsha is using straightedge and compass to do the construction as the line on the line through P perpendicular to line. It was the converted to the equation ax + by + c = 0. Perpendicular lines are those lines rays or segments on the intersect to form right angles.

As a result, the significance of the construction Marsha is doing a line through P perpendicular to line are the aforementioned. Therefore, option (d) is correct.

Answer:

[tex]p=38.84[/tex]

Step-by-step explanation:

Since there are two half circles, we just need to work to find the perimeter of a whole circle. The formula for the perimeter (circumference) of a circle:

[tex]C=2\pi r[/tex]

We need to know the radius to find the circumference. By studying the figure, we know that the length of the entire shape is 12 ft. We also know that on either side of the half circles, the length is 3 ft. If we divide 12 by 3, we see that the total length of 12 ft can be broken into 4 parts, each measuring 3 ft. The radius is half the diameter, so the radius is 3. Insert the values:

[tex]C=2*3.14*3[/tex]

Simplify:

[tex]C=18.84[/tex]

Now add the values of the exposed parts of the rectangle:

[tex]18.84+3+3+3+3+3+3=36.84[/tex]

The perimeter is 36.84.

:Done

Answer:

V = 8.6 in^3

Step-by-step explanation:

The circumference is given by

C = 2 * pi *r

8 = 2 * pi *r

Divide each side by 2pi

8 /2pi = r

Using 3.14 for pi

1.27388535 = r

The volume of a sphere is given by

V = 4/3 pi r^3

V = 4/3 (3.14) (1.27388535)^3

V =8.654847391

To the nearest tenth

V = 8.6 in^3

Answer:

To find x, y, z, p and q, you need to know about the property of Rhombus.

13y + 10 = 7y + 16 (pair of equal opposite sides)

=> 6y = 6

=> y = 1

x = 7x + 16 (2 equal adjacent sides)

  = 7*1 + 16

  =23

z = 90 deg (angle between 2 diagonals)

q = 22 deg (isosceles triangle)

p = 90 - 22 = 68 deg (right triangle)

Step-by-step explanation:

Given

f(x) = (x - 6)(x + 5)

To find the zeros, let f(x) = 0, that is

(x - 6)(x + 5) = 0

Equate each factor to zero and solve for x
