There are 100 students in a drawing contest, and 58 of them are girls. What percent of the students in the contest are girls?

Answers

Answer 1

You take 58/100 and you’ll get your answer and you should get 58%

Answer 2

There are 100 students in a drawing contest and 58 of students are girls. What percent of students in the drawing contest are girls?

The fraction [tex]\frac{58}{100}[/tex] represents the number of girls in the drawing contest out of all the students.

To find out what percent of the students are in the drawing contest, we can change [tex]\frac{58}{100}[/tex] into a percent.

We can first reduce the fraction by dividing both the numerator and denominator by the Greatest Common Factor of 58 and 100 using 2.

58 ÷ 2 = 29

100 ÷ 2 = 50

Our reduced fraction is [tex]\frac{29}{50}[/tex].

29 ÷ 50 = 0.58

0.58 × 100 = 58%

Therefore, 58% of the students in the drawing contest are girls.

There are 5 cars to be displayed in 5 parking spaces, with all the cars facing the same direction. of the 5 cars, 3 are red, 1 is blue, and 1 is yellow. if the cars are identical except for color, how many different display arrangements of the 5 cars are possible?

Answers

For questions like these, I believe you use permutations. Basically you mutiply all the numbers in the set together. so in this case there are five, so you multiply numbers 1-5 together in order to get the total arrangements possible.

For example :
[tex]1 \times 2 \times 3 \times 4 \times 5 = 120[/tex]
There you go :)

Final answer:

The question relates to combinatorial mathematics and asks for possible arrangements of 5 cars of three different colors. Treating identical colors as one entity, we find that there are 6 ways to arrange the color groups and another 6 ways to arrange the red cars among themselves, resulting in 36 possible arrangements.

Explanation:

The subject of this question is combinatorial mathematics. We're asked how many different arrangements there are if we have 5 cars to be displayed in 5 parking spaces, with the condition that the cars are identical besides their color; 3 of them are red, 1 is blue, and 1 is yellow.

Since three cars are identical (red ones), we treat them as one. So initially, we have three 'entities' to arrange: the red group (of 3 cars), the blue car, and the yellow car. These can be arranged in 3! (which means 3 factorial, or 3 * 2 * 1) = 6 ways.

However, within the red group, those 3 red cars can be arranged amongst themselves in 3! = 6 ways.

Therefore, to get the total number of arrangements, we multiply these results together, giving us: 6 * 6 = 36 different arrangements.

An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 20mL. The height of the water rose to 30.2mL. If the mass of the stone was 25g what was its density?

Answers

Answer:
density = 2.4509 g/ml

Explanation:
1- getting the volume of the stone:
since the stone has an irregular shape, the volume of the stone would be equal to the increase in the volume of the stone after placing the stone in it.
Initial volume of water = 20 ml
Final volume of water = 30.2 ml
volume of stone = final volume of water - initial volume of water
volume of stone = 30.2 - 20 = 10.2 ml

2- getting the density of the stone:
we have:
volume of stone = 10.2 ml
mass of stone = 25 g
Therefore, we can get the density as follows:
density = mass / volume
density = 25 / 10.2
density = 2.4509 g/ml

Hope this helps :)

Final answer:

To find the density of the stone, subtract the initial volume of water from the final volume, then divide the mass of the stone by the volume. The density of the stone is 2.45 g/cm³.

Explanation:

In order to find the density of the stone, we first need to calculate its volume. The volume can be determined by subtracting the initial volume of water in the graduated cylinder from the final volume with the stone submerged. In this case, the volume of the stone is 30.2 mL - 20 mL = 10.2 mL.

Next, we can use the formula for density: density = mass/volume. Plugging in the given values, we have density = 25 g/10.2 mL.

Since density is mass divided by volume, we need to convert mL to g/cm³. 1 mL is equal to 1 g/cm³. Therefore, the density of the stone is 25 g/10.2 mL = 2.45 g/cm³.

A tunnel is in the shape of a parabola. The maximum height is 16 m and it is 16 m wide at the base, as shown below.

What is the vertical clearance 7 m from the edge of the tunnel?

Answers

Answer: 15.75 m

Explanation:

1) Since the vertex is at the origin, i.e point (0,0), and the simmetry axis is paralell to the vertical axis, you know that the canonical equation of the parabola is:

y = -4px², where p is the focal distance.

You can also use y = ax², where a = -4p.

2) Using y = ax², you can find a from the fact that at x = 8 (one edge of the tunnel), y = - 16 ( negative value of the height).

Substitute those values (8,16) in the equation y = ax², and you get:

- 16 = a (8²) ⇒ a = - 16 / 64 = - 1/4

Therefore, the equation of the parabola is: y = (-1/4)x².

3) To find the vertical clearance at 7 m from the edge of the tunnel, you must realize that the x-coordinate is x = 8 - 7 = 1.

Then, find y for x = 1:

y = (-1/4)(1²) = - 1/4 = - 0.25

That is the y-coordinate; the clearance is the 16m - 0.25m = 15.75m

Below is the graph of y=b^x. Find b.

Answers

y = b^x

Therefore, the value of b is the same as the value of y when x =1
From the graph,
When x = 1, y = 0.5
Therefore, b = 0.5

To confirm this

From the graph,

When x = -1, y = 2
Since y = b^x
2 = b^-1
2 = 1/b
2b = 1
b = 0.5

When x = -2, y = 4
Since y = b^x
4 = b^-2
4 = 1/(b^2)
b^2 = 1/4
b = √(1/4)
b = 1/2
b = 0.5

Therefore, it is conformed that b = 0.5

Functions can be represented as equations, and equations can be represented as functions.

The value of b is 1/2

The graph is given as:

[tex]\mathbf{y = b^x}[/tex]

From the graph, we have the following point:

The answer to this question is 1. If we differentiate each piece, we get

                                  { -2x,       x>0

A number cube is rolled 120 times. The number 4 comes up 47 times. What is the experimental probability of rolling a 4? What is the theoretical probability of rolling a 4?

B. 47/120; 1/6 ******
C. 4/47; 1/6
D. 1/6; 47/120

Am I Correct?

Answers

Yes you are.
(Your answer is B, right?)

A number cube is rolled 120 times. The number 4 comes up 47 times.

We have to determine the experimental probability of rolling a 4.

The formula to evaluate probability of an event is given by:

Probability = [tex] \frac{Favourable outcomes}{Total outcomes} [/tex]

So, Probability of rolling a 4 = [tex] \frac{ Total number of times when 4 appears}{Total number of times number cube rolled} [/tex]

= [tex] \frac{47}{120} [/tex]

Now, we have to find the theoretical probability of rolling a 4.

Total number of outcomes of number cube = {1,2,3,4,5,6}

Probability of rolling a 4 = [tex] \frac{1}{6} [/tex]

So, Option B is the correct answer.

If 6 is 30% of a value,
a.what is 70% of that value? b8 is omlwhat is 10%of the value?

Answers

70% is 14. And 10% is 2

so if 6 is 30% of a value we know that the value let's say x multiplied by .3 is 6. so we can write an equation to solve for the value x
[tex].3x = 6 \\ x = \frac{6}{.3} \\ x = 6 \times \frac{10}{3} = 20[/tex]

so our value is 20 and as 10% of 20 is 2 we see 30% of 20 is 2×3=6

now we want to find 70% of 20 and 10% of 20. we already know 10% of 20 is 20 because to find 10% we take the value 20.0 and move the decimal 1 place to the left which gives us 2.0. To find 70% we can multiply 20 by .7 or since we know 10% just multiply that by 7 because 10% ×7 =70% so 2×7=14 so 14 is 70% of 20. solving the other way we get
[tex]20 \times .7 = 20 \times \frac{7}{10} = \frac{20}{10} \times 7 = 2 \times 7 \\ = 14[/tex]
so we can see we are correct!

Amy owns a graphic design store. She purchases a new printer to use in her store.
The printer depreciates by a fixed rate of 14% per year. The function
V = 2,400(1 – 0.14)t can be used to model the value of the printer in dollars after
t years.

Question:

Part A: Explain what the parameter 2,400 represents in the equation of the function.
Part B: What is the factor by which the printer depreciates each year?
Part C: Amy also considered purchasing a printer that costs $4,000 and depreciates by 25% each year. Which printer will have more value in 5 years? Justify your answer by showing/explaining your work.

Answers

Given that the printer depreciates at the rate of 14% p.a. This has been modeled by the function V=2400(1-0.14)^t, this follows an exponential form given by
y=a(b)^x
where:
V=y
a=2400
b=1-0.14
x=t
thus:
Part A: Explain what the parameter 2,400 represents in the equation of the function.
The parameter 2400 represents the initial value of the printer at time t=0. This is the original value.

Part B: What is the factor by which the printer depreciates each year?
The factor of depreciation is 14% percent. This is the rate at which the printer depreciates and it accounts for the value of the printer at the end of every year.

Part C: Amy also considered purchasing a printer that costs $4,000 and depreciates by 25% each year. Which printer will have more value in 5 years?
Value after 5 years of the $2400 printer that depreciates at 14% per year will be:
V(t)=2400(1-0.14)^5=$1,129.025

Value after 5 years of the $4000 printer that depreciates at 25% per year will be:
F(t)=4000(1-0.25)^t
F(5)=4000(1-0.25)^5=$949.22

The printer that costs $2400 will be more valuable compared to the printer that cost $4000

A newly hatched channel catfish typically weighs 0.3 grams. During the first 6 weeks of life, its growth is approximately exponential, increasing by about 10% each day. Find the weight at the end of four weeks. (Hint: Be sure to change the number of weeks to days before plugging into the formula!) Formula: A=C(1+r)t

0.53g
4.33g

Answers

Answer: second option 4.33 g

Explanation:

1) The formula is given: A = C(1+r)ˣ ↔ (I used x instead of t just do to limitations of the math editor. Keep in mind that here x is time in days.

2) r is the rate of increasing given: 10% = 10/100 = 0.1

3) C is the initial weight and A is the final weight after x (or t) days.

4) The equation leads to:

A = 0.3 (1 + 0.1)ˣ = 0.3(1.1)ˣ

x = number of days = 7 × number of weeks = 7 × 4 = 28 days

4) Compute:

A = (0.3g)(1.1)²⁸

A = 4.33g ← answer

Final answer:

The weight of a newly hatched channel catfish after four weeks of exponential growth is approximately 1.14 grams.

Explanation:

To find the weight at the end of four weeks, we need to convert the number of weeks to days since the growth rate is given in terms of daily percentage increase. The formula to calculate exponential growth is A = C(1 + r)^t, where A is the final weight, C is the initial weight, r is the growth rate, and t is the number of periods. In this case, C = 0.3 grams, r = 0.10 (10% daily increase), and t = 4 weeks x 7 days/week = 28 days. Plugging in these values, we get A = 0.3(1 + 0.10)^28. Evaluating the expression, the weight at the end of four weeks is approximately 1.14 grams.

A student wonders if protists are more common at certain depths than others. After considering factors such as photosynthesis, the student hypothesizes that the surface waters of his neighborhood pond contain the greatest number of different protist species. To test his hypothesis, the student collects several water samples from different depths in the same region of his neighborhood pond. Which data must be collected from the samples in order to address the hypothesis? As the weight of purchased items increases, the shipping charges increase, as shown in the table below. Weight, in oz Total Shipping Cost not more than 5 $9.50 more than 5, not more than 10 $13.25 more than 10, not more than 15 $17.00 more than 15, not more than 20 $20.75 Assuming only positive domain values, which statement is true of the graph that represents the data in the table? Beginning at 5 ounces, the graph is discontinuous at every fifth integer of the domain. The range values graphed for the set of data are $10, $14, $17, and $21. For every 1 ounce increase in weight, the total shipping cost increases by $3.75. The left side of each horizontal interval is a closed circle, and the right side is an open circle.
