Answer 2

The probability of getting a marble marked with a number greater than 4 is [tex]\frac{1}{9}[/tex].

What is probability?

Probability is the measure of happening or non-happening of outcomes of random experiment.

Probability formula

P(E) = Number of favorable outcomes/Total number of outcomes

where,

P(E) is the probability of an event.

According to the given question.

Total number of marbles in jar = 18

⇒ Total number of outcomes = 18  

( 6 red marbles, 6 black marbles, and 6 green marbles)

But it is given that, black or red marble is randomly selected.

Therefore, the total number of outcomes reduced to 12.

Numbers which are greater than 4 among 1 to 6 are 5 and 6.

Total number of numbers which are greater than 4 in jar = 2 × 3 =6

But we have to select only black or red marble.

Therefore,

Total number of favorable outcomes = 4

The probability of selecting a marble greater than 4 which are red

= [tex]\frac{4}{12} =\frac{1}{3}[/tex]

The probability of selecting a marble greater than 4 which are black

= [tex]\frac{4}{12} = \frac{1}{3}[/tex]

Therefore, the probability of getting a marble marked with a number greater than 4 [tex]=(\frac{1}{3}) (\frac{1}{3} )=\frac{1}{9}[/tex]

Hence, the probability of getting a marble marked with a number greater than 4 is [tex]\frac{1}{9}[/tex].

write in standard form 5.2-0.5x=1.9y​

Answers

Answer:

5.2 = 0.5x + 1.9y

Step-by-step explanation:

In this case "standard form" signifies an equation resembling Ax + By = C.

Adding 0.5x to both sides results in  5.2-0.5x + 0.5x = 1.9y​ + 0.5x, or

5.2 = 0.5x + 1.9y, which is in "standard form."

There are 4 cones with a height of 18 meters. The Radius of the Cones: Cone 1: 1 Cone 2: 2 Cone 3: 3 Cone 4: 4 What's the volume of each cone? Express your answer in terms of pi.

Answers

Answer:

24π

54π

96π

Step-by-step explanation:

Cone 1:

Height, h= 18 meters

Radius, r = 1

Volume of cone 1 = πr²h/3

= (π * 1² * 18)/3

= (π * 1 * 18)/3

= 18π/3

= 6π

Cone 2:

Height, h= 18 meters

Radius, r = 2

Volume of cone 2 = πr²h/3

= (π * 2² * 18)/3

= (π * 4 * 18)/3

= 72π/3

= 24π

Cone 3:

Height, h= 18 meters

Radius, r = 3

Volume of cone 3 = πr²h/3

= (π * 3² * 18)/3

= (π * 9 * 18)/3

= 162π/3

= 54π

Cone 4:

Height, h= 18 meters

Radius, r = 4

Volume of cone 4 = πr²h/3

= (π * 4² * 18)/3

= (π * 16 * 18)/3

= 288π/3

= 96π

A certain island contains 540 cats and 675 dogs. What is the ratio of cats to dogs on this island?

Answers

Answer:

4 : 5

Step-by-step explanation:

every 4 cats there are 5 dogs

The ratio of cats to dogs is 4  : 5

The ratio of cats to dogs is:

Number of cats : Number of dogs

540  :  675

Now you take them down to their lowest terms by dividing both numbers by their highest common factor.

The highest common factor of 540 and 675 is 135 so divide both sides by 135:

540 / 135   :  675 / 135

4  :  5

The ratio of cats to dogs is therefore 4 : 5.

14² + 48² = 50²

196 + 2304 = 2500

2500 = 2500

So the first answer, 50, 48, 14, could be the measurements of a right triangle.

Consider the function graphed below.

Which function does the graph represent?

Answers

Answer:

its c on edge 2021

Step-by-step explanation:

The function of graph is

f(x) = { x²                   , x < 1

         1/3x+ 2/3        , x > 1

What is function?

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

For first part of graph we have the equation of parabola as

y = a (x- h)² + k

At origin, h= 6 and k= 0

y = ax²

and, Passing through the point (1, 1)

1 = 1 (a)

a= 1

So, the equation first is y= x².

Now, for second part using slope intercept form

y= mx+ b

As, Passing through (1, 1) and (4, 2)

(y- 1) = (2-1)/ (4-1) (x- 1)

y-1 = 1/3 (x-1)

y - 1 = 1/3 x - 1/3

y - 1/3 x = -1/3 + 1

y - 1/3x = 2/3

y= 1/3x + 2/3

So, the function of graph is

f(x) = { x²                   , x < 1

         1/3x+ 2/3        , x > 1
