Using an exponential function, it is found that the total amount of waste these households are expected to produce in 2020 is of 117,649 tones.

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem, we have that:

Thus, the equation is:

[tex]A(t) = 125000(1 - 0.02)^t[/tex]

[tex]A(t) = 125000(0.98)^t[/tex]

2020 is 3 years after 2017, hence the amount is:

[tex]A(3) = 125000(0.98)^3 = 117649[/tex]

The total amount of waste these households are expected to produce in 2020 is of 117,649 tones.

Step-by-step explanation:

A

25 - x  > 8 ( substitute x = 18 )

25 - 18 > 8

7 > 8 ← False statement

B

0.5x < 7 ( substitute x = 18 )

Step-by-step explanation:

The colored triangle that stands in the center of the pyramid is a right triangle. The side of the pyramid is 64, so the bottom edge of the colored triangle is 32. That 32 inch side is a leg of the right triangle. The other length given is the hypotenuse, 68 inches. We can use Pythagorean theorem.

x^2 + 32^2 = 68^2

x^2 + 1024 = 4624

x^2 = 4624 - 1024

x^2 = 3600

square root both sides.

x = 60

Answer:

grab two of our datas in a row

goal: get to y=mx+h

m = (-6-(-12))/(0-(-2))=6/2=3

now we have: y=3x+h

z=0 → y = -6 → h = -6

answer: y = 3x-6

The equation best describes the relationship between the corresponding values of x and y shown in the table is:

Option C. y = 3x - 6

To determine the equation that best describes the relationship between x and y in the table, we can apply the slope-intercept formula, which has the form: y = mx + b, where "m" is the slope and "b" is the y-intercept.

From the table, let's calculate the slope using two points (x, y):

Using (-2, -12) and (0, -6):

Slope (m) = (y2 - y1) / (x2 - x1) = (-6 - (-12)) / (0 - (-2)) = 6 / 2 = 3

Now, let's use the slope (m) and any point (x, y) from the table to find the y-intercept (b).

Using (0, -6):

y = mx + b

-6 = 3 * 0 + b

b = -6

So, the equation that best describes the relationship is:

y = 3x - 6

Thus, the correct option is C. y = 3x - 6.

Step-by-step explanation:

Two types of tickets are adult(a) and student(s).  Let a and s stand for the numbers of tickets bought for each.

We know that a + s = 32  {The school buys a total of 32 tickets.}

The total cost is $288, made up of:

 a*($12.50) and s*($8.50)

Thus, we can write:

a*($12.50) + s*($8.50) = $288

The two equations:

a + s = 32

a*($12.50) + s*($8.50) = $288

are all we need to calculate the numbers of a and s tickets.

===

a = 32-s

a*(12.50) + s*(8.50) = 288

(32-s)*(12.50) + s*(8.50) = 288

400 - 4s = 288

-4s = -112

s = 28 tickets

---

a + s = 32

a + 28 = 32

a = 4 tickets

Answer: The triangles are not congruent.

Step-by-step explanation:

We are given that the two triangles both contain a congruent angle and a congruent side. Additionally, the two triangles also share a side with each other, which is the center horizontal side (the one bisecting the two congruent angles). This "shared" side tells us that this side is congruent in both triangles, meaning that both triangles have two congruent sides with a non-included congruent angle among them.

However, because the two triangles only have two congruent sides, and the angle shared by each triangle is not included between the two sides, the triangle would be "congruent" by SSA, which is not a triangle congruency theorem or postulate.

Therefore, the two triangles are not congruent.

Step-by-step explanation:

Using the normal distribution, it is found that:

a) 68.2% of standardized test scores are between 406 and 644.

b) 31.8% of standardized test scores are less than 406 or greater than 644.

c) 2.3% of standardized test scores are greater than 763.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

Item a:

The proportion is the p-value of Z when X = 644 subtracted by the p-value of Z when X = 406, hence:

X = 644:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{644 - 525}{119}[/tex]

[tex]Z = 1[/tex]

[tex]Z = 1[/tex] has a p-value of 0.841.

X = 406:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{406 - 525}{119}[/tex]

[tex]Z = -1[/tex]

[tex]Z = -1[/tex] has a p-value of 0.159.

0.841 - 0.159 = 0.682.

0.682 = 68.2% of standardized test scores are between 406 and 644.

Item b:

Complementary event to the one found in item A, hence:

1 - 0.682 = 0.318.

0.318 = 31.8% of standardized test scores are less than 406 or greater than 644.

Item c:

The proportion is 1 subtracted by the p-value of Z when X = 763, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{763 - 525}{119}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a p-value of 0.977.

1 - 0.977 = 0.023

0.023 = 2.3% of standardized test scores are greater than 763.

..................

Answer:

11

Step-by-step explanation:

According to the empirical rule, 95% of data in a normal distribution will be between 2 standard deviations below the mean and 2 standard deviations above the mean.

Therefore, 2 standard deviations above the mean would be 21+2(5)=21+10=31 and 2 standard deviations below the mean would be 21-2(5)=21-10=11.

Thus, the lower value is 11

Answer:

x = 2, 3.

Step-by-step explanation:

Since the equation equals 0, we can determine that:

3x-6=0

-x+3=0

Let's solve 3x-6=0.

Add 6 to both sides of the equation:

3x=6

Divide both sides by 3:

x=2

Let's solve -x+3=0.

Subtract 3 from both sides of the equation:

-x=-3

Divide by -1:

x=3
