Answer:

2000 points

Step-by-step explanation:

Given:

Number of questions in a study guide (Q) = 100

Number of points for 1 question (n) = 20

Now, total number of points is calculated using unitary method by multiplying number of questions and number of points in one question.

Therefore, the total number of points is given as:

Total points = [tex]n\times Q[/tex]

Total points = [tex]20\times 100[/tex]

Total points = [tex]2000[/tex]

Hence, the study guide is worth 2000 points.

Answer:

[tex]f^{-1}[/tex](x) = x - 5

Step-by-step explanation:

Let y = f(x) and make x the subject

y = x + 5 ( subtract 5 from both sides )

y - 5 = x

Change y back into terms of x, thus

[tex]f^{-1}[/tex](x) = x - 5

Point is equidistant from points A and B because a point on a perpendicular bisector is equidistant from the endpoints of the segment it makes up.

The angle bisector theorem states that a triangle's opposite side is divided into two halves by an angle bisector that is proportional to the triangle's other two sides.

A point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects, therefore if mACD = 90°, point D is equidistant from points A and B.

Any point on the perpendicular bisector is simply equal distance from both endpoints of the line segment on which it is drawn, according to the perpendicular bisector theorem.

The answer is that point  is equidistant from points A and B because a point on a perpendicular bisector is equidistant from the endpoints of the segment it makes up.

To prove that point D is equidistant from the jungle gym and monkey bars (points A and B), we would utilise the geometrical concept of congruent triangles. This involves drawing line segments from D to A and D to B, and if those segments are congruent, then point D is equidistant from points A and B. The process would encompass drawing a perpendicular bisector from point D to segment AB.

To demonstrate that point D is equidistant from the jungle gym and the monkey bars, Beth would need to use specific concepts from geometry. First, she would need to identify points A and B as the jungle gym and monkey bars respectively. Point D is the location of the swings.  

Next, she would draw line segments from D to A and D to B. If line segment DA is congruent to line segment DB, this means they have the same length, hence point D is an equal distance from both points A and B (the jungle gym and the monkey bars).

This can be proved through congruent triangles if a perpendicular bisector is drawn from point D to line segment AB. Such concept echoes that a point on a perpendicular bisector of a line segment is equidistant from the endpoints of the segment. The resulting triangles would be congruent, meaning every part, including the sides DA and DB, would be the same.

The volume of the square pyramid is: 3072 ft³

What is the volume of the square pyramid?

The volume (V) of a square pyramid can be calculated using the formula:

V = ⅓ × base area × height

The base area of a square pyramid is given by the formula:

base area = base edge²

Given that the base edges (a) is 24 ft and the slant height (s) is 20 ft, we can calculate the height (h) of the pyramid using the Pythagorean theorem.

h = √(20² - (24/2)²)

h = √256

h = 16 ft

Thus:

Volume = ⅓ * 256 * 16

Volume = 3072 ft³

Answer:

0 ≤ t ≤ 5.

Step-by-step explanation:

In the function [tex]f(t)[/tex], [tex]t[/tex] is the independent variable. The domain of [tex]f[/tex] is the set of all values of [tex]t[/tex] that this function can accept.

In this case, [tex]f(t)[/tex] is defined in a real-life context. Hence, consider the real-life constraints on the two variables. Both time and volume should be non-negative. In other words,

The first condition is an inequality about [tex]t[/tex], which is indeed the independent variable.

However, the second condition is about [tex]f[/tex], the dependent variable of this function. It has to be rewritten as a condition about [tex]t[/tex].

[tex]\begin{aligned} f(t) &\ge 0 &&\text{Assumption} \cr 80000 - 16000\, t& \ge 0 && \text{Definition of} ~ f \cr 80000 & \ge 16000\, t && \begin{aligned}&\text{Add $16000\, t$} \\[-0.5em] & \text{to both sides of the inequality}\end{aligned} \cr 5 &\ge t &&\begin{aligned}&\text{Divide both sides of} \\[-0.5em] & \text{the inequality by $16000$}\end{aligned} \cr t &\le 5 && \text{Flip the inequality}\end{aligned}[/tex].

Hence, t ≤ 5.

Combine the two inequalities to obtain the domain:

0 ≤ t ≤ 5.

Step-by-step explanation:

There are three numbers on the first spinner.  Two are not even (1 and 3).

So there are 2 possible outcomes that work: 1 and 6 or 3 and 6.

Final answer:

There are two outcomes that meet the criteria of the question: not showing an even number on the first spinner and showing a 6 on the second spinner.

Explanation:

The question asks how many outcomes result in an odd number on the first spinner and show a 6 on the second spinner. The first spinner has three equal sectors labeled 1, 2, and 3, of which two are odd (1 and 3). The second spinner has four equal sectors labeled 3, 4, 5, and 6, but we are only interested in the outcome when the spinner shows a 6.

Since we want the first spinner to show an odd number, we ignore the 2, leaving us with 1 and 3 as the possible outcomes for the first spinner. For the second spinner, we are only interested in the outcome of 6. This means we multiply the two outcomes from the first spinner (1 and 3) by the one outcome from the second spinner (6), resulting in two possible outcomes: (1,6) and (3,6).

Therefore, the correct answer is there are two outcomes that do not show an even number on the first spinner and show a 6 on the second spinner.

The value of B = [tex]\dfrac{1}{16}[/tex]

The value of C =  [tex]\dfrac{25}{16}[/tex]

The value of D =  [tex]\dfrac{5}{4}[/tex]

Step-by-step explanation:

Given as :

The following relations are as

[tex]\dfrac{d}{5}[/tex] =4 A           ...........1

d = 20 B                                       ...........2

d = [tex]\dfrac{4}{5}[/tex] C           ...........3

And d = [tex]\dfrac{5}{4}[/tex]

Now, From the above relations

Put the value of d in eq 1

∵ 4 A = [tex]\dfrac{d}{5}[/tex]

So, d = 5 × 4 A

Or, [tex]\dfrac{5}{4}[/tex] = 20 A

∴ A = [tex]\frac{\frac{5}{4}}{20}[/tex] = [tex]\dfrac{1}{16}[/tex]

I.e The value of A =  [tex]\dfrac{1}{16}[/tex]

Again

From eq 2

∵ d = 20 B

Put the value of d

So, [tex]\dfrac{5}{4}[/tex]  = 20 B

Or, B = [tex]\frac{\frac{5}{4}}{20}[/tex]

∴ B = [tex]\dfrac{1}{16}[/tex]

I.e The value of B = [tex]\dfrac{1}{16}[/tex]

Similarly

From eq 3

d = [tex]\dfrac{4}{5}[/tex] C  

Put the value of d

So, [tex]\dfrac{5}{4}[/tex] =  [tex]\dfrac{4}{5}[/tex] C    

Or, C = [tex]\frac{5\times 5}{4\times 4}[/tex]

∴ C = [tex]\dfrac{25}{16}[/tex]

Answer:

The probability that exactly 2 trucks are going over the speed limit is 56.3% (rounding to the next tenth)

Step-by-step explanation:

1. Let's check all the information provided to us to answer the question correctly:

Probability that a truck will be going over the speed limit on I-80 between Cheyenne and Rock Springs = 75%.

Number of trucks in the random sample = 5

2. What is the probability that exactly 2 trucks are going over the speed limit?

Let's recall that two events are independent if the result of the second event is not affected by the result of the 1st event. If a first truck goes over the speed limit and a second truck does the same are independent events, the probability of both events occurring is the product of the probabilities of the individual events.

P (T₁ and T₂) = P (T₁) * P (T₂)

P (T₁ and T₂ ) = 0.75 * 0.75 = 0.5625

The probability that exactly 2 trucks are going over the speed limit is 56.3% (rounding to the next tenth)

Answer:

So it will take roughly 18.4471905815477 years.

(round appropriately if needed)

Step-by-step explanation:

A=P(1+r/n)^(nt)

6000=2000(1+0.06/4)^(4*t)

6000/2000 = (1+0.06/4)^(4*t)

3 = (1+0.06/4)^(4*t)

3 = (1.015)^(4*t)

log(3) = log((1.015)^(4*t))

log(3) = 4*t*log(1.015)

log(3)/(4*log(1.015)) = t

t = log(3)/(4*log(1.015))

t = 18.4471905815477

Using the ratio of 7 girls to 3 boys and knowing that there are 9 boys, we find that there are 21 girls at the movie by setting up a proportion and solving for the number of girls.

Explanation:

To find out the number of girls at the movie, we need to use the ratio given, which is 7 girls to 3 boys or 7:3. Since there are 9 boys, we can set up a proportion to solve for the number of girls (G):

7 girls : 3 boys = G girls : 9 boys

Now we cross multiply and solve for G:

7 * 9 = 3 * G

63 = 3 * G

Divide both sides by 3 to find the number of girls:

G = 63 / 3

G = 21

Therefore, there are 21 girls at the movie.

AB ║ CD. (Proved)

Step-by-step explanation:

See the attached diagram of the triangle.

It is given that Δ ACD is an isosceles triangle.

Therefore, AC = AD and ∠ ACD = ∠ ADC, ⇒ ∠ 3 = ∠ 4 .......... (1)

Again, given that ∠ 1 = ∠ 3 ........... (2)

Now, from equations (1) and (2) we can write, ∠ 1 = ∠ 4

Now, AB and CD are two straight lines and AD is the transverse line and hence, ∠ 1 and ∠ 4 are alternate angles that are equal.

Therefore, AB and CD are parallel straight lines and AB ║ CD. (Proved)
