List all the ways to select two members from S with repetition. The order in which the members are selected is not important. Fo

nexus9112 [7]

Answer:

15 ways

Step-by-step explanation:

We are given that a set S={E,F,G,H,J}

We have to find the number of ways to select two members from S with repetition.

Combination formula

$\binom{n}{r}=\frac{n!}{r!(n-r)!}$

We have n=5 , r= 2

Number of ways in which two members from S can be selected when repetition is not allowed= $5C_2=\frac{5!}{2!(5-2)!}$

Number of ways in which two members from S can be selected when repetition is not allowed= $\frac{5\times4\times3!}{2\times1 3!]$

Number of ways in which two members from S can be selected when repetition is not allowed= $5\times 2=10$

When a member repeat then combination

{E,E},{F,F},{G,G},{H,H},{J,J}

There are 5 combination when a member is repeat and select two members from S.

Total number of ways in which to select two members from S with repetition =10+5=15 ways

Enter the equation of the circle described below. <br> Center (-1,4), radius = sqrt3

slava [35]

The equation of a circle always follows this:

(x - x1) + (y - y1) = r^2

x1 and y1 represent the coordinates as POSITIVE numbers and the r represent the radius

Your answer is (x + 1) + (y - 4) = 3

A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).

Ilia_Sergeevich [38]

Answer:

The error in the students work is

y -(-8) + 8 = -6x + 12 + 8

subtracting a negative is adding

y+8

They should subtract 8 from each side instead of adding 8 to each side

Step-by-step explanation:

We can use point slope form since we are given a point and the slope

y-y1 = m( x-x1)

y--8 = -6(x-2)

y+8 = -6(x-2)

Distribute the -6

y+8 = -6x+12

Subtract 8 from each side

y+8-8 = -6x+12-8

y = -6x+4

The error in the students work is

y -(-8) + 8 = -6x + 12 + 8

subtracting a negative is adding

y+8

They should subtract 8 from each side instead of adding 8 to each side
