What is the product of 4xy and y2 + 2x?4xy 3 + 4xy
4xy 2 + 8x 2y
4xy 3 + 8x 2
4xy 3 + 8x 2y

Answers

Answer 1

Answer: The product of 4xy and y² + 2x can also be written as
4xy(y² + 2x)

When we have brackets like this, we multiply whatever is left of the brackets by everything inside.

1) 4xy multiplied by y²
    4xy x y² = 4xy³

2) 4xy multiplied by 2x
    4xy x 2x = 8x²y

3) Add together 4xy³ and 8x²y
    4xy³ + 8x²y

A line that passes through the point (–1, 3) has a slope of 2. Find another point on the line.a. (–3, 2)
b. (1, 4)
c. (1, 5)
d. (0, 5)

Answers

Using the slope-intercept form of a line, the equation can be generated
y = mx + b

m = 2
and we can solve for b by substituting the given coordinates where the line passes through
3 = 2(-1) + b
b = 5

So, the equation of the line is
y = 2x + 5

Trying the options using the equation, the answer is
d. (0,5)

A and B are two events. P(A)=0.5 , P(B)=0.4 and P(A and B)=0.3 . What is the value of P(A or B) ?

Answers

Answer: The required value of $P(A\cup B).$ is 0.6.

Step-by-step explanation: Given that A and B are two events such that

$P(A)=0.5,~~P(B)=0.4,~~P(A\cap B)=0.3.$

We are to find the value of $P(A\cup B).$

From the laws of probability, we have

$P(A\cup B)=P(A)+P(B)-P(A\cap B)=0.5+0.4-0.3=0.9-0.3=0.6.$

Thus, the required value of $P(A\cup B).$ is 0.6.

Answer: 0.6

Work Shown:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.5 + 0.4 - 0.3

P(A or B) = 0.9 - 0.3

P(A or B) = 0.6
