Answer:

D

Step-by-step explanation:

Answer:

Since the frequency of the numbers vary, the students are not effective at generating random numbers.

Step-by-step explanation:

If they were effective, all the numbers should have around the same probability of being generated.

Between 1 and 20 there are 20 numbers, so the frequency of each number should be around 100%/20 = 5%.

Since the frequency of the numbers vary, the students are not effective at generating random numbers.

Answer:

The answer is option C, that is, (2,6)

Answer:

Let the required number be 'x'.

Then,

x + 2.2 = 34.5 - 12.3

or, x = 34.5 - 12.3 - 2.2

or, x = 20

So, the required number is 20.

Answer:

$50 with 35% off is $32.50

Step-by-step explanation:

This is the model to find a discounted price:

n with x% off

100 - x = y

n * 0.y = p

With this example, we would find the discounted price like shown below:

$50 with 35% off

100 - 35 = 65

$50 * 0.65 = $32.50

Answer:

Could an airplane take off and clear this tall building?  YES

Step-by-step explanation:

Trigonometry

The building and the ground form a right (90°) angle. The path of the airplane (assumed a straight line) completes the right triangle.

The takeoff angle of the plane θ=15° has the height of the building (450 feet) as the opposite side and the horizontal distance from the end of the runway (2500 feet) as the adjacent side.

The tangent of θ is defined as the following ratio:

[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

[tex]\displaystyle \tan \theta=\frac{450}{2500}[/tex]

[tex]\displaystyle \tan \theta=0.18[/tex]

Calculating the inverse tangent function:

[tex]\theta=\arctan 0.18[/tex]

[tex]\theta\approx 10^\circ[/tex]

This means the angle needed to clear the tall building is about 10° and it's within the maximum airplane's takeoff angle.

Could an airplane take off and clear this tall building?  YES

Answer:

8.71

Step-by-step explanation:

the area that is shaded is a big shape then two smaller shapes taken out of it

that means you can find the area of the big shape ignoring that there are holes then subtract the area of the holes

big shape side length is 5*2

=10

small shape 1:

0.3*0.3

=0.09

small shape 2:

0.6*2

=1.2

10-(0.09+ 1.2)

10-(1.29)

=8.71

Answer:

19 batches of homemade muffins

Step-by-step explanation:

1 cup per 1 batch

You will get an amount of batches equal to the amount of cups of sugar, so if there are 19 cups there would be 1 batch of homemade muffins for each of the cups.

Answer:

19 batches of muffins

Step-by-step explanation:

She uses 1 cup for 1 batch which means

1 cup = 1 batches

So if you multiply 19 by 1 you should get 19 which means

19 cups = 19 batches

Step-by-step explanation:

Answer:

32 Miles

Step-by-step explanation:

Okay so this will take a moment:

Let's set up the following variables:

d = total distance of the trip

v = some rate of velocity/travel

Note: t is not a variable here as it would denote time, but we know the time, so rate of travel as a variable is next best.

With those variables, we can set up 3 equations as follows:

d - 35v = 65

d - 63v = 44

d - 79v = x

The equations being read as:

[total distance] - [time and rate of travel] = [distance remaining]

Now if we restructure each of those equations, you will have:

d = 35v + 65

d = 63v + 44

d = 79v + x

Now you can treat this like a system of equations. First we will solve for the variable: v

Since the total distance remains the same, we can set up the following equation:

subtract 35v from both sides

subtract 44 from both sides

Now if we turn it around:

The common factor of both of these numbers is 7, so divide both by 7:

Therefore:

That was a lot. NOW that you know the value of v, you can find the total distance that Eric needs to travel, so plug it into one of the equations:

d = 35( [tex]\frac{3}{4}[/tex] ) + 65

Solve, and you get:

d = 91.25 miles = [tex]\frac{365}{4}[/tex] miles

Now that you know what the variables: v and d , you can solve for x in the other equation: d = 79v + x

[tex]\frac{365}{4}[/tex] = 79 ( [tex]\frac{3}{4}[/tex] ) + x

Multiply.

[tex]\frac{365}{4}[/tex] = [tex]\frac{237}{4}[/tex] + x

Subtract.

[tex]\frac{365}{4}[/tex] - [tex]\frac{237}{4}[/tex] = x

Simplify.

x = [tex]\frac{128}{4}[/tex] = 32

Voila! 32 Miles to go! Good Luck!
