Answer:

  120 cubes will fill the box

Step-by-step explanation:

You want to know the number of 1-inch cubes it takes to fill a box that is 5 cubes long, 4 cubes wide, and 6 inches tall.

To cover the bottom of the box, Chan needs to make an array of cubes that has 4 rows with 5 cubes in each row. That layer will have ...

  4 × 5 = 20 . . . . cubes per layer

Each layer occupies 1 inch of height, and the box is 6 inches high. The volume of the box will be filled with six of these layers. That will take this many cubes:

  (6 layers) × (20 cubes/layer) = 6 × 20 cubes = 120 cubes

Chan will need 120 cubes to fill the box.

Tiger shows you, step by step, how to Isolate x (Or y or z) in a formula

The points scored by Rodney is 20 points.

The points scored by Justin is 19 points.

x + y = 39 equation 1

x - y = 1 equation 2

Where:

x = points scored by Rodney

y = points scored by Justin

In order to determine the points scored by Justin, take the following steps:

Subtract equation 2 from equation 1 :

2y = 38

Divide both sides of the equation by 2

y = 38/2

y = 19 points

To determine the value of x, substitute for y in equation 2

x - 19 = 1

Combine similar terms: x = 19 + 1

Add similar terms together: x = 20

The actual weight of the animal is between 450.2 and 426.2 pounds

An equation is an expression that shows the relationship between two or more numbers and variables.

Inequality can be used to show that two variables or numbers are not equal to each other.

The weight of the larger animals can be off by 12 pounds. Let x represent the actual weight of the animal. If the scale reads 438.2 lbs, hence:

|x - 438.2| = 12

x - 438.2 = 12; or -(x - 438.2) = 12

x = 450.2; or x = 426.2

The actual weight of the animal is between 450.2 and 426.2 pounds

Using it's concept, the average rates of change are given as follows:

a. 1264.03 soda per person per year.

b. 5851.89 soda per person per year.

c. 128010.89 soda per person per year.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For this problem, the function is given as follows:

f(x) = 5.852x^4 - 0.002x³ + 0.006x² + 0.029x + 47.855.

From 1990 to 1996, we have t = 0 to t = 6, hence:

Hence the rate is:

(7632.01- 47.855)/6 = 1264.03.

1264.03 soda per person per year.

From 1990 to 2000, we have t = 0 to t = 10, hence:

Hence the rate is:

(58566.75 - 47.855)/10 = 5851.89.

5851.89 soda per person per year.

From 2005 to 2010, we have t = 15 to t = 20, hence:

Hence the rate is:

(936354.84 - 296300.39)/5 = 128010.89.

128010.89 soda per person per year.

Using probability we get (a) P(1|A) = 1/2 and (b)P(1|B) =3/4 , hence P(1|A) ≠ P(1|B).

Probability is the study of chance . The part of mathematics known as probability deals with fractional representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, 0 denotes the event's impossibility and 1 denotes certainty.

Probability is calculated by the fraction possible outcomes ÷ total outcomes

a) The first spinner has the total 4 sections. so there are 4 total outcomes.

Favorable outcome = 1

Total number of favorable outcome=2

Probability P(1|A) = favorable outcome ÷ total outcome

∴ P(1|A) =2/4 or P(1|A) =1/2

b) The first spinner has the total 4 sections. so there are 4 total outcomes.

Favorable outcome = 1

Total number of favorable outcome=3

Probability P(1|B) = favorable outcome ÷ total outcome

∴ P(1|B) =3/4 or P(1|B) =3/4

c)Therefore P(1|A)≠P(1|B)  so the events A and B are dependent.

Miguel uses 300 mL Solution B and 600 mL Solution A.

Let x represent the amount of Solution B used.

2x = the quantity of Solution A used.

Solution A is alcohol = 12%.

Solution B is alcohol = 16%.

Given that 12% = 0.12 and 16% = 0.16, we can calculate the following equation:

2x(0.12) + x(0.16) = 120 (Recall that pure alcohol has a concentration of 100% = 1.00.)

0.24x + 0.16x = 120

0.40x = 120

x = 300 mL

Thus, Miguel  makes use of 300 mL of Solution B and 2(300) = 600 mL of Solution A.

Answer:

f(0) = 5, f(7) = 1328, f(-5) = -460

Step-by-step explanation:

Answer:

≈67.81

Step-by-step explanation:

The average rate of change of f(x) = x - 2√x on the interval [1, 9] is 1/2.

It is a measure of how much the function changed per unit, on average, over that interval.

We have,

f(x) = x - 2√x

On the interval [1,9].

[1, 9] = [a, b]

The average rate of change:

= f(b) - f(a) / b - a

= f(9) - f(1) / 9 - 1

= [(9 - 2√9) - (1 - 2√1)] / 8

= [ (9 - 6) - (1 - 2) ] / 8

= (3 + 1) / 8

= 4 / 8

= 1/2

Thus the average rate of change of f(x) = x - 2√x on the interval [1, 9] is 1/2.

Answer:

Step-by-step explanation:

The experimental probability of next person to have Blue eyes is 3/7.

Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.

It is based on the possible chances of something to happen.

Probability (P) = Number of a Favourable outcome {n (E)} / Total number of outcomes {n (S)}  

Simply,  P = n (E) / n (S)

Given, Eye colors of the people

Green = 2

Blue    = 30

Brown = 38

To find the probability of next person to have blue eyes, first we will add the given eye colors

Total number of Eye Colors = 2 + 30 + 38 = 70

Number of Blue Eyes = 30

Then, Probability to have blue eyes P(blue) = Number of Blue Eyes / Total number of Eye Colors

                                                      = 30/70

                                                      = 3/7

So, there is 3/7 chances to next person to have blue eyes.

Answer:

Step-by-step explanation:

Answer:

4a.) 0.0005 = 5 x 10 to the exponent -4

4b.) 0.0025 = 2.5 x 10 to the exponent -3

5a.) 2 x 10 to the exponent -2 = 0.02

5b.) 16 x 10 to the exponent -4 = 0.0016

Tip:

The number being multiplied has to be less than or equal to 10. Count the places the decimal point moves from the end of the number to the number in the original equation.

Example: 0.05 = 5 x 10 to the exponent -2

0.05 has 2 spaces for the decimal point to move up to 5 going right. We use a negative decimal because 0.05 is less than 5. Here is an example where the exponent is positive:

5000 = 5 x 10 to the exponent 3

5000 has 3 spaces for the decimal point to move down to 5 going left.
