Answer:

The probability that exactly two of the selected bulbs are rated 23-watt is:

= 19%

Step-by-step explanation:

Number of fluorescent light bulbs in the box = 21

7/21 = 13-watt rated light bulbs

8/21 = 18-watt rated light bulbs

6/21 = 23-watt rated light bulbs

The probability of selected a 23-watt rated light bulb = 6/21 = 28.57%

Size of random selection of bulbs = 3

The probability that 2 out of these 3 bulbs are 23-watt rated light bulbs is:

= 6/21 * 2/3 = 19%

b) The probability of selecting 2 of the 3 bulbs from exactly the 23-watt rated bulbs is the probability of the 23-watt rated bulbs being selected given the chance of selecting 2/3.

Answer:

x = 14

Step-by-step explanation:

3 (x - 3) + 8x = 5 (2x + 1)​

FOIL: 3x - 9 + 8x = 10x +5

Move all the x terms to one side and all the constants to the other:

3x + 8x - 10x = 5 + 9

Combine like terms: x = 14

Answer:

x:0 y: 3

x: 1 y: -1

x: 2 y: 1

Step-by-step explanation:

The coordinates of line is (0, -3), (1, -1) and (2, 1)

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y = 2x - 3

Now, putting x=0

y= -3

and, x= 1

y= 2(1)-3

y = -1

and, x= 2

y=2 (2)- 3

y = 1

Hence, the coordinates of line is (0, -3), (1, -1) and (2, 1)

other sides =94.4 mm

largest perimeter=94.4+94.4+82.4=271.2 mm=27.12 cm

Answer:

Yes

Step-by-step explanation:

The inequality is y<-3x+4

If you plug in (-2, -4), you get:

-4<-3(-2)+4

-4<10

So the point satisfies the equation.

Answer:

If the vertical line intersects the graph in at most one point, then the given graph represents a function. If the vertical line intersects the graph in more than one point, then the given graph does not represent a function.

I HOPE IT HELPS

TAKE CARE

Step-by-step explanation:

Answer:

Step-by-step explanation:

For a graph to be a function, there must not be more than one element in the range for each element of the domain.

If x represents the doman, and y represents the range (as usual, in graphing) then each value on the the x-axis should not have more than one point in the graph on it, directly above it, or directly below it. Like if you had a point (5, 7) and also had point (5, -7), that is not a function. The x, 5, has more than one y-value  paired with it.

Visually, any vertical line through the graph should not intersect the graph at more than one point. If it does, then the graph is not a function.

This is called the vertical line test.
