Answer: 4/35

Step-by-step explanation:

Number of red marbles = 4

Number of blue marbles = 5

Number of green marbles = 6

Total number of marbles = 4+5+6 = 15

When a red marble is picked, the probability is 4/15, then to pick a green marble after that, we have 14 marbles left and probability of picking green is 6/14.

Now, probability of choosing a red marble from the bag, not putting it back, and then choosing a green marble will be:

= 4/15 × 6/14

= 24/210

= 4/35

Answer:

2x^2+3x^4+1

Step-by-step explanation:

a trinomial  is composed by three monomials.

So only A and B can be correct

the degree of a polynomial is the same of the monomial that compose it with the biggest degree

so the answer is B because the monomial with the biggest degree is 3x^4 (its degree is 4)

Answer:

Step-by-step explanation:

This is because,

According to Triangle Inequality Property:

Measurement of any two sides of a triangle is always greater than the third side.

Here,

10 + 16 = 26 > 21

10 + 16 = 26 > 22

10 + 16 = 26 > 22

But,

10 + 16 = 26 < 27

Hence,

Option D: 27 can't be the measurement of the triangle.

Answer:

81 : 25

Step-by-step explanation:

Area of square ABCD = side * side = 5 * 5 = 25 cm²

Area of square PQRS = 9 * 9 = 81 cm²

Ratio of square PQRS to square ABCD = 81 : 25

This cannot be reduced, as there are no common factors

Answer:

length = 6

width = 3 1/2

Step-by-step explanation:

l = length

w = width

l = 2w-1

w(2w-1) = 21

2w² - 1 - 21 = 0

(2w - 7)(w + 3) = 0

w = 7/2 = 3 1/2

find 'l':  l = 2(7/2) - 1 = 7-1 = 6

Step-by-step explanation:

E(x) = 3.15.

By displaying the proportion of data points (referred to as "bars") that fall inside a certain range of values, a histogram gives a visual explanation of numerical data. A vertical bar graph and a histogram are comparable.

E(X) = ∑( x ∗ P(x))

Given a probability histogram for a discrete random variable X.

We will drive the P(x) for every value of x.

P(X=1)=0.1

P(X=2)=0.2

P(X=3)=0.3

P(X=4)=0.25

P(X=5)=0.15

Putting these values in a summation equation to find E(x)

E(x) = 1*0.1 +2*0.2 + 3*0.3 + 4*0.25 + 5* 0.15

E(x) = 3.15

Therefore E(x) for the given histogram far random variable x will be 3.15.

Answer: first graph is F(x) = 0.5(x-6) (x+2)

Second graph f(x) = (x - 3) ( x + 1 )

Third graph f(x) = -2(x - 1) (x + 3 )

Step-by-step explanation:

Type functions into Desmos graphing calculator and it will plot the points for you.

PLATO

The required quadratic function shown in the graph is

f(x)=0.5(x+2)(x-6).

Let us suppose the quadratic function

[tex]f(x)=a(x-\alpha )(x-\beta )[/tex]......(1)

where α and β are roots of the quadratic equation f(x)=0

Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where a≠0

From the shown graph we can see the roots of f(x)=0 as:

[tex]\alpha =-2[/tex]

[tex]\beta =6[/tex]

So, (1) becomes [tex]f(x)=a(x+2 )(x-6 )[/tex].....(2)

Since the graph is intersecting the y-axis at (0, -6)

So,  (0, -6) will satisfy the (2)

So put x=0 and f(x)= -6 in (2)

[tex]-6=a(0-2)(0-6)[/tex]

[tex]a=\frac{-1}{2}=0.5[/tex]

So, [tex]f(x)=0.5(x+2 )(x-6 )[/tex]

Thus, the required quadratic function shown in the graph is

f(x)=0.5(x+2)(x-6).

Answer:

the area of the circle is 4π

Step-by-step explanation:

The computation of the area of the circle is shown below:

As we know that

The area of the circle = πr^2

where

diameter = 4

So radius = diameter ÷ 2

= 4 ÷ 2

= 2

Now the area of the circle is

= π × 2^2

= 4π

hence, the area of the circle is 4π

Answer:

b = 2, c = - 8

Step-by-step explanation:

Given x = a is a root then (x - a) is a factor

Here the roots are x = - 4 and x = 2 , then the corresponding factors are

(x + 4) and (x - 2)

The equation is then the product of the factors , that is

(x + 4)(x - 2) = 0 ← expand factors using FOIL

x² + 2x - 8 = 0

with b = 2 and c = - 8

Answer:

5x² - 5x + 17

Step-by-step explanation:

(3x² + 7) + (2x² - 5x + 10)

Combine the like terms.

3x² + 2x² = 5x²

-5x does not have a like term, so there is no change.

7 + 10 = 17

Combine them, and the final equation is

5x² - 5x + 17.

Answer: 5x² - 5x + 17

Step-by-step explanation:

(3x^2+7)+(2x^2-5x+10)

3x^2 + 2x^2

-5x

7 + 10

5x^2 - 5x + 17
