evaluate p-q if p=14 and q=13

Answers

Answer:

Value of [tex]p-q=1[/tex]

Step-by-step explanation:

We need to find [tex]p-q[/tex]

[tex]p-q=14-13\\\\=1[/tex]

[tex]\huge\boxed{\sf{Hello\:there!}}[/tex]

We are asked to evaluate p-q.

Now, if we aren't given the value of every variable, evaluating this expression is impossible. However, we do have the value of p (14) and the value of q (13)

We plug these numbers instead of the variables:

p-q

p=14

q=13

14-13

1

Hence, the value of the expression is 1.

When a stone is dropped from a height, the time taken to fall, t, is proportional to the square root of the distance fallen, d.

Write down a formula, using k, connecting the time taken to fall and the distance traveled.

Answers

Step-by-step explanation:

We know that in kinematics we can write the formula for uniformly accelerated bodies:

s = 1/2 a t^2 + v0 t + s0

In our case s0 (initial deployment)  = 0m and v0 (initial velocity) = 0

So:

s = 1/2 a t^2

Now we isolate t:

t = [tex]\sqrt[2]{\frac{2s}{a} }[/tex]

All proportionalities are obvious.

Note: I forgot to say that a, the acceleration, is the gravitational acceleration. It can be g or -g depending on how you'll choose the reference system.

Census data from a city of 150,000 residents produced the income distribution shown here: A distribution curve of income in thousands of dollars. The curve is right skewed with a mean between 50 and 100. Suppose that we were to take random samples of 100 residents from this population and calculate ˉ x as the sample mean income of the residents in each sample.

Answers

Using the Central Limit Theorem, it is found that the shape of [tex]\bar{x}[/tex] is approximately normal.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, the distribution is not normal, however the sample size is of 100 > 30, hence the Central Limit Theorem is applicable and the shape of [tex]\bar{x}[/tex] is approximately normal.

Lily has $2. 75 in her pocket, consisting of dimes and quarters. If there are 17 coins in all, how many of each does she have?.

Answers

Answer:

Lily has 7 Quarters and 10 Dimes

Step-by-step explanation:

Let's use pennies instead of $.

Let D and Q stand for the numbers of Dimes and Quarters, respectively.

We are told that there are 17 coins total:

  D + Q = 17

We also learn that they amount to 275 (pennies).  We can write that as:

10D + 25Q = 275  [Each D is worth 10 pennies, etc.]

We have two equations and two unknowns.  We can rearrange one equation to find the value of either of the unknowns, and then use that it the second equation.

I'll rearrange the first:  

 D + Q = 17

  D = 17 - Q

Now use this value of D in the second equation:

10D + 25Q = 275

10(17-Q) + 25Q = 275

170 - 10Q + 25 Q = 275

15Q = 105

Q = 7  :  7 Quarters.

Since D + Q = 17:

D + 7 = 17

D = 10 Dimes

==========================================

Let's check these results:

Q = 7 Quarters

D = 10 Dimes

1.  Is this 17 coins in total?  (7+10 = 17)  YES

2.  Does this add to $2.75?  (10*10) + (7*25) = 275 cents?

 (100 + 176) = 275 (cents)   YES

Mr. Lamb is missing a solution for his next patient. He has a cylindrical test tube which is 4 cm across the inside. The depth of the tube is 9 cm. What is the volume of the cylinder in mL?

Answers

Answer:

V=113.04mL

Step-by-step explanation:

The question is asking us to find the volume of a cylinder in mL. For this, we can use the equation V=[tex]\pi r^{2} h[/tex].

We know the diameter, 4cm, and the height, 9cm.

In order to solve, we must first find the radius.

r=1/2d

r=1/2(4)

r=2cm

We can now plug this into our equation.

V=[tex]\pi r^{2} h[/tex]

V=[tex]\pi (2)^{2} (9)[/tex]

V=[tex](3.14)(2)^{2} (9)[/tex]

V=113.04mL

You went 160 miles in 20 hours. What is the constant of proportionality that relates the y, the distance in miles to x, the time in hours?

Answers

Answer:

X = Y times 8

Step-by-step explanation:

You need to figure out how many miles you can go in an hour.

160/x and 20/1

20x=160

x=8

You can go 8 miles in 1 hour.

Therefore, if X is 1 and Y is 1

1 = 8

1 hour equals 8 miles

===========================================================

Explanation:

Refer to the remote interior angle theorem (some books call it the exterior angle theorem). That says we can add the two interior angles and the sum is the exterior angle that is not adjacent to either interior angle.

(interiorAngle1) + (interiorAngle2) = exterior angle

(5x) + (2x+6) = 8x-11

7x+6 = 8x-11

6+11 = 8x-7x

17 = x

x = 17

----------------

Or the slightly longer method has you follow these steps:

y = missing interior angle in the upper right corner

The angle (8x-11) and angle y are supplementary

(8x-11) + (y) = 180

y = 180-(8x-11)

y = 180-8x+11

y = -8x+191

For any triangle, the three interior angles always add to 180

(angle1)+(angle2)+(angle3) = 180

(5x)+(2x+6)+(-8x+191) = 180

-x+197 = 180

-x = 180-197

-x = -17

x = 17
