No Possible Triangle

Step-by-step explanation:

Sine cannot be greater than 1

No Possible Triangles

The equation of a line is y = mx +b

m = slope - which is equal to 1

x = x coordinate

b = y intercept (where the line hits the y axis)

y = y coordinate.

The point (2, 0) shows that when x = 2, y = 0. So we can plug that into the equation:

0 = 1(2) + b

0 = 2 + b

0 - 2 = 2 -2 +b

-2 = b

So the equation of the line is y = x - 2

a) The conditional relative frequency of a student who does not plan to attend college, given that they plan to live at home is of: 0.5714 = 57.14%.

b) There is a negative association between not attending college and living on their own.

The relative frequency of an event in an experiment is obtained as the number of desired outcomes of the experiment divided by the number of total outcomes of the experiment.

For the conditional relative frequency of a student who does not plan to attend college, given that they plan to live at home, in item a, the outcomes are given as follows:

Hence the relative frequency is of:

p = 0.2/0.35 = 0.5714 = 57.14%.

Among people who plan to live on their own, the relative frequency of people who plan to attend college is of:

0.55/0.65 = 0.846 = 84.6%.

Hence there is a negative association between not attending college and living on their own, as people who live on their own are significantly more likely to attend college then people who do not live on their own.

El saco tiene un precio original de 400 soles.

En este problema tenemos el caso de un precio de compra (P'), en soles, que es resultado de aplicar dos descuentos consecutivos al precio original del saco (P), en soles. El precio es el resultado de multiplicar el precio original por los dos factores de porcentaje, descrito por la siguiente fórmula:

P' = P · (1 - r₁ / 100) · (1 - r₂ / 100), 0 ≤ r₁, r₂ ≤ 100.

Donde:

Si sabemos que P' = 224, r₁ = 30 y r₂ = 20, entonces el precio original del saco es:

224 = (1 - 30 / 100) · (1 - 20 / 100) · P

224 = 0.7 · 0.8 · P

P = 224 /(0.7 · 0.8)

P = 400

El precio original del saco es de 400 soles.

Probability of guessing the correct order = [tex]\frac{1}{720}[/tex]

What is Probability?

Probability gives us the information about how likely an event is going to occur

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Probality of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

There are 10 numbers from 1 to 10

Number of favourable outcomes = 10 [tex]\times[/tex] 9 [tex]\times[/tex] 8

                                                       = 720

There is only one correct order

By using the concept of Percentage, it is obtained that

New Salary of Vineeth = Rs. 15000

What is Percentage?

Suppose there is a number and the number has to be expressed as a fraction of 100. The fraction is called percentage.

For example 2% means 2 is expressed as a fraction of 100.

Here, the concept of percentage has been used.

Original salary of Vineeth = Rs. 25000

Percentage decrease in salary = 40%

Decrease in salary = [tex]\frac{40}{100}\times 25000\\[/tex]

                               = Rs. 10000

Answer:

No

Step-by-step explanation:

1) Write out the inequality to get a better understanding

m ≤ -12

From this we can see that m can be any number less than -12!

2) Find out possible solutions

As -12 is a negative number, any number less than it would have a larger absolute value.

Some examples of numbers less than -12 would be -15, -13, -36 ect.

HINTS:

It may be easy to confuse which number is greater or smaller than a negative number.

To make sure that we don't make a mistake, we can always put the numbers on a number line!

Any number to the left of it, is smaller, and any number to the right, is larger!

The probability that exactly 14 seeds will germinate is 0.109

According to the company, 80% of lima bean seeds germinate.

Callie purchases 20 lima beans.

To determine: the likelihood that exactly 14 seeds will germinate.

We use the binomial distribution to obtain the required probability when we need to track the success and failure of multiple objects (multiple Bernoulli trials)

Let X be the random variable that tracks the number of seeds that germinate out of a total of 20 seeds. The success rate is 80%, or 0.8.

Thus X ~ B(20,0.8)

The probability of X = x is given by:

P(X=x) = 20[tex]C_{x}[/tex][tex](0.8)^{x}[/tex][tex](1-0.8)^{20-x}[/tex]

Thus

P(X=14) = 20[tex]C_{14}[/tex][tex](0.8)^{14}[/tex][tex](1-0.8)^{20-14}[/tex]

P(X=14) = 38760 × 0.04398 × 0.000064 = 0.109

Answer:

Step-by-step explanation:

In the book, they gave you the values of 'a', 'b', and 'c', and you're supposed to find the value of 'd'.

If you have two points on the line, then the slope of the line is

                      (the change in 'y') divided by (the change in 'x') .

If the two points are (a, b) and (c, d), then the slope of the line is

                      (d - b) divided by (c - a),

and you have to find the value of 'd' that makes that whole expression

equal to 1/2.

                                     (d - b) / (c - a) = 1/2

Multiply each side by  (c - a):     (d - b) = 1/2(c - a)

Add 'b' to each side:                    d        =  1/2(c - a)  +  b

If you know the values of 'a', 'b', and 'c', you can find the value of 'd'.

The total distance that Sylvie will have driven is, 459 miles.

What is distance?

The measurement of distance between two objects or points can be quantitative or occasionally qualitative. Distance in physics or common language can refer to a physical length or an assumption based on other factors.

Let,  Sylvie is going on vacation. She has already driven 60 miles in one hour. She then travels for 7 hours at an average speed of 57 miles per hour.

In 7 hours Sylvie travel 7 x 57 = 399 miles.

So, the total distance is,

399 + 60 = 459 miles

Hence, the total distance that Sylvie will have driven is, 459 miles.

distribution of the total number of tumors produced in the whole population over a one-year period by this kind of radiation is 0, 1, 2, ..................104000.

let, x denote the total number of hits,

y denotes the number of hits by a particle in a year or an individual,

one per week ⇒ 52 per year

therefore, rate = 52 per year

since it is very rare to hit all individuals, we can use Poisson distribution.

therefore by using the formula p (x = x) = (e^(-rate) × rateˣ) ÷ x! ; x = 0, 1, 2, ............( 2000 × 52)

p (x = 2) = (e⁻⁵² × 52ˣ) ÷ x! ; x = 0, 1, 2, ............104000

now each hit has a harm of probability 10⁻⁵.

so p(total no. of tumors produced over a one year period)

= {e⁻⁵² × 52ˣ} ÷ x! × 10⁻⁵ ; x = 0, 1, 2, ............104000

therefore total no. of tumors = 2000 × (e⁻⁵² × [tex]52^{x.10^{-5} }[/tex] ) ÷ x!  × xⁿ ; x = 0, 1, 2, ............104000

In the triangle ABC, the side lengths, in order from the greatest to the least, are : AC > AB > BC.

We are given a triangle. The vertices of the triangle are A, B, and C. The measures of the angles ∠A, ∠B, and ∠C are 36°, 84°, and 60°, respectively. We need to arrange the side lengths in order from the greatest to the least.

The side lengths are proportional to their opposing angles in a triangle. It means that the side opposite the largest angle is the largest side, and vice versa. The angles arranged in descending order are : 84° > 60° > 36°. The angles arranged in descending order according to the vertices are : B > C > A. The order of the lengths of the opposite sides must be the same.
