(a) 48 %

(b) 74 %

Add the numbers associated with the name and then do 150 divided by that number, and then make the top number equal to 100. Whatever you did to make that top number 100 do the same thing to the bottom number.

Chips suppose a computer chip manufacturer rejects 2% of the chips produced because they fail presale testing.

Artyom0805 [142]

(a) P( fifth one is bad) = P( first 4 are OK) * P(5th is bad)

= (0.98)^4 * 0.02 = 0.0184 or 1.84%

(b) this will be (0.98)^10 = 81.70%

7 red, 8 yellow, 9 white......total = 24 roses

probability first pick is white : 9/24
probability second pick is yellow : 8/23

probability of both : 9/24 * 8/23 = 72/552 reduces 3/23 <====

Express , twelve times a number minus six is less than or equal to

xenn [34]

Answer:

12x - 6 ≤ - 18

Step-by-step explanation:

We will call "a number" x so

Twelve times a number would be:

12x

Then minus 6

12x - 6

Now we add the less than or equal to sign.

12x - 6 ≤

This is equal to negative eighteen, so:

12x - 6 ≤ - 18

As a bonus we can also solve for x.

12x - 6 = - 18 Add 6 to each side.

12x - 6 + 6 = -18 + 6

12x = -18 + 6

12x = -12 Divide each side by 12

12x/12 = -12/12

x = -12/12

x = -1

So we can say when x ≤ -1 Then 12x - 6 ≤ -18

Indicate the equation of the line, in standard form, that passes through (2, -4) and has a slope of 3/5. Enter your answer into

yulyashka [42]

The equation of the line is $y = (3/5)x + 26/5$

<u>Step-by-step explanation:</u>

The line passes through the point (2,-4).
The line has the slope of 3/5.

To find the equation of the line passing through a point and given its slope, the slope-intercept form is used to find its equation.

<u>The equation of the line when a point and slope is given :</u>

⇒ $(y-y1) = m(x-x1)$

where,

m is the slope of the line.
(x1,y1) is the point (2.-4) in which the line passes through.

Therefore, the equation of the line can be framed by,

⇒ $(y-(-4)) = 3/5 (x-2)$

⇒ $(y+4) = 3/5(x-2)$

Take the denominator 5 to the left side of the equation.

⇒ $5(y+4) = 3(x-2)$

Now, multiply the number outside the bracket to each term inside the bracket.

⇒ $5y+20 = 3x -6$

⇒ $5y = 3x-26$

Divide by 5 on both sides of the equation,

⇒ $y = (3/5)x + 26/5$

Therefore, the equation of the line is $y = (3/5)x + 26/5$
