In a bag of counters, there are 3 times as many red counters as
blue.
There are twice as many blue counters as yellow counters.
What is the ratio of red : blue : yellow?

Answers

Answer 1

Answer:

The ratio is 6:2:1.

Step-by-step explanation:

Let's denote:

Blue counter b

Red counter r

Yellow counter y.

There is given

r=3b (three times more red as blue) [1]

and

b=2y (twice more blue as yellow.) [2]

Now, replacing [2] to [1] gives

3*2y=r

6y=r.

Hence, the ratio is 6:2:1, because r=6y and b=2y.

n a certain wilderness area 1.4 mountain lions are seen each year, on average. what is the probability that in a given year exactly two mountain lions will be seen in this wilderness area? (assume that sightings are independent from each other and that the probability of seeing a mountain lion stays constant.)

Answers

Therefore  ,the probability that in a given year exactly two mountain lions will be seen in this wilderness area is P =0.2417.

How does probability work?

Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%. When an event has a probability of 0, it has no possibility of happening, whereas when it has a probability of 1, it is almost certain to happen. When an event has a probability of 0.45 (45%), there are 45 out of 100 chances that it will occur.

Here,

λ=1.2

=> P(X =x) = [tex]\frac{e^{-\lambda} * \lambda^{x} }{x!}[/tex]

=> P(X=2) = [tex]\frac{e^{-1.4} * 1.4^{2} }{2!}[/tex]

=> P(X=2) = 0.2466 * 1.96 /2

=>P(X=2) = 0.2417

Therefore  ,the probability that in a given year exactly two mountain lions will be seen in this wilderness area is P =0.2417.

The value of x is 7.2.

The Perimeter of quadrilateral TWNB is 70.

what is perimeter?

A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length, a two-dimensional shape, or both. The circumference of a circle or an ellipse is its perimeter. There are numerous practical uses for calculating the perimeter.

Given:  TWNB ≅ RDHY

NW = 3x,

RD = 5x - 19.6

RY = 2x + 5.6

HD = 5x - 14.4

TW = 3x - 5.2

BN = x + 4.8

We have to find the value of x

As, TWNB ≅ RDHY

⇒ TW ≅ RD,  WN ≅ DH,  NB ≅ HY,  TB ≅ RY

Consider, TW ≅ RD

  3x - 5.2 = 5x - 19.6

19.6 - 5.2 = 5x - 3x

       14.4 = 2x

           x = 7.2

Hence, the value of x is 7.2.

Now to find the perimeter of quadrilateral TWNB.

Perimeter of TWNB = TW + WN + NB + TB

Here,

TW = 3x - 5.2 = 16.4

WN = 3x = 21.6

NB = x + 4.8 = 12

TB = RY = 2x + 5.6 = 20

Hence,

Perimeter of TWNB = 16.4 + 21.6 + 12 + 20 = 70.

How to represent equation in slope intercept form?

Equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

m = slope of the lineb = y-intercept

As you drive, the number of minutes since you filled the tank and the number of gallons remaining in the tank are related by a linear function.

After 40 minutes, you have 28.4 gallons left. An hour after filling up, you have 26.25 gallons left.

Let's find the slope.

(40, 28.4)(60, 26.25)

m = 26.25 - 28.8 / 60 - 40

m = -2.15 / 20

m = - 0.1075

Hence, let's find the y-intercept using (40, 28.4)

y = - 0.1075x + b

where

x = number of minutesy = amount of fuel remaining

Therefore,

28.4 = -0.1075(40) + b

28.4 + 4.3 = b

b = 32.7

Therefore, the equation of the line is y = -0.1075x + 32.7

At what point on the graph is the rate of reaction the greatest?

Answers

The instantaneous rate at the beginning of a reaction, or when t = 0, is known as the starting rate of the reaction.

What is rate of Reaction ?

The rate at the beginning of the reaction may be determined using the graph of change in product over time or change in reactant over time. The highest rate on the curve is the beginning rate. Since the reactants are concentrated at their highest at the beginning, the most collisions are occurring.

Rates of response can be depicted in graphs. To depict the pace of reaction, we may create a graph of product (or reactant) against time. The pace of reaction will be the gradient of the graph. The pace of response increases with increasing gradient steepness.

The instantaneous rate at the beginning of a reaction, or when t = 0, is known as the starting rate of the reaction. The beginning rate is equal to the slope of the reactant concentration versus time curve at time zero, which is negative.

What are the 3 types of dynamic semantics?

Answers

In linguistics, dynamic semantics is a theory of meaning that is based on the idea that the meaning of a sentence is determined by the way it is used in context, rather than by its compositionality. Within dynamic semantics, there are a few different approaches that have been developed. Three types of dynamic semantics are Discourse representation theory, situation semantics and event semantics.

Discourse representation theory: This theory proposes that the meaning of a sentence is determined by its role in the context of a discourse (i.e., a conversation or written text). The meaning of a sentence is represented as a set of constraints on the possible interpretations of the discourse, and the interpretation of the discourse is determined by the way these constraints are resolved.

Situation semantics: This theory proposes that the meaning of a sentence is determined by the way it refers to a particular situation or state of affairs. The meaning of a sentence is represented as a set of conditions that must be satisfied for the sentence to be true in a particular situation.

Event semantics: This theory proposes that the meaning of a sentence is determined by the events or actions it describes. The meaning of a sentence is represented as a set of conditions that must be satisfied for the events or actions described in the sentence to occur.

What is the nature of roots of the quadratic equation 2x² √ 5x 1 0?

Answers

The roots of the quadratic equation 2x² √5x + 1 = 0 are two complex numbers.

To solve for the roots of the quadratic equation 2x² √5x + 1 = 0, we must first use the Quadratic Formula to solve for x. The Quadratic Formula is x = (-b ± √b²-4ac)/2a. In this equation, a = 2, b = √5, and c = 1. We then simplify the equation to be x = (-√5 ± √(5²-4(2)(1))/2(2). This simplifies to x = (-√5 ± √9i)/4. The two solutions to this equation are x = (-√5 + 3i)/4 and x = (-√5 - 3i)/4. Since both solutions involve complex numbers, the roots of 2x² √5x + 1 = 0 are two complex numbers.

x = (-√5 ± √(5²-4(2)(1))/2(2)

How many unique sets of 3 prime numbers exist for which the sum of the numbers is 44?

Answers

The unique set of 3 prime numbers for which the sum of the numbers is 44 are {2, 5, 37}, {2, 11, 31}, {2, 13, 29} and {2, 19, 23}.

What is Prime Number?

Prime numbers are the numbers in the set of natural numbers for which 1 and the number itself are the only factors of it.

The numbers which are not prime are called composite numbers.

We have to find the set of 3 prime numbers which on adding yields 44.

Now 44 is a composite number and also an even number.

We also know that adding two odd numbers as well as adding two even numbers always gives the even number.

2 is the only even prime number.

So if we take this set which is not including 2, then by adding odd + odd + odd gives the odd number.

But the answer we needed is 44, which is even.

So this set always contain 2 as one of the prime number.

So by adding the other two prime numbers, we must get 42.

Thus we got,

{2, 5, 37}  = 2 + 5 + 37 = 44

{2, 11, 31} = 2 + 11 + 31 = 44

{2, 13, 29} = 2 + 13 + 29 = 44

{2, 19, 23} = 2 + 19 + 23 = 44

Hence the unique 3 set of prime numbers are  {2, 5, 37}, {2, 11, 31}, {2, 13, 29} and {2, 19, 23} for which the sum is 44.

What is a system of equations?

Generally, To solve this system of equations by graphing, you can start by graphing each equation separately on the same set of axes.

For the first equation, Y = x - 1, you can start by plotting a few points to get a feel for the graph.

, if x = 0, then Y = -1.

If x = 1, then Y = 0.

If x = 2, then Y = 1.

You can continue plotting points like this to get a better idea of what the graph looks like.

For the second equation, y = 1/2x + 1, you can do the same thing. For example,

if x = 0,

then y = 1.

If x = 1,

then y = 1.5.

If x = 2,

then y = 2.

Again, you can plot a few more points to get a better sense of the graph.

Once you have graphed both equations, you can look for the point where the two graphs intersect.

This point will be the solution to the system of equations. In this case, the solution is (4,3), so the correct answer is C.

Step-by-step explanation:

20% of $8.00 is actually 0.20 x 8

0.20 x 8 = 1.60

Answer:

$1.60

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20

Second, you need to find out what 20% of your $8.00 meal cost is.This is always done by multiplying 0.20 by $8.00, or

0.20 x $8.00=$1.60.

So, the amount of tip you are going to leave is $1.60.

A sociologist is studying the effect of having children within the first 2 years of marriage on the divorce rate. Using hospital birth records, she selects a simple random sample of 200 couples who had children within the first 2 years of marriage. Following up on these couples, she finds that 80 couples are divorced within 5 years. Let p= the population proportion of couples who had children within the first 2 years of marriage and are divorced within 5 years. What is a 90% plus four confidence interval for the proportion of couples who had children within the first 2 years of marriage and are divorced within 5 years?Question options:0.402 ± 0.0880.402 ± 0.0670.402 ± 0.0570.402 ± 0.035

Answers

The proportion of couples who had children within the first 2 years of marriage and are divorced within 5 years is [tex]0.4\pm 0.057[/tex].

What is a confidence interval?

The confidence interval (CI) is a range of values that, with a particular level of confidence, is likely to include a population value.

A population mean that sits between an upper and lower interval is frequently stated as a percentage.

Given, Out of 200 couples who have children with 2 years, 80 couples had been divorced within 5 years.

Therefore the proportion of couples who have had children and divorce

= (80/200).

= 0.4.

We know the confidence interval for a population proportion is,

[tex]p = p' \pm z_{\frac{\alpha}{2}} \sqrt{\frac{p'(1 - p')}{n}[/tex].

Now, [tex]z_{\frac{\alpha}{2}[/tex] at 90% confidence interval is 1.645 and n = 200.

Therefore, [tex]p = 0.4\pm 1.645} \sqrt{\frac{0.4'(1 - 0.4)}{200}[/tex].

[tex]p = 0.4\pm 1.645} \sqrt{\frac{0.4\times0.6}{200}[/tex].

[tex]p = 0.4\pm 1.645\times0.0346[/tex].

[tex]p = 0.4\pm 0.057[/tex].
