3 0

Step-by-step explanation:

a)\sf \: Factor 6x2−3x \\  \sf {6x}^{2} −3x \\ \sf \: =3x(2x−1) \\  \sf \: Answer:3x(2x−1) \\

b)Let's factor x²+3x−28

⇒x²+3x−28

⇒x² - 4x + 7x - 28

⇒(x² - 4x) + (7x - 28)

⇒x( x - 4) + 7(x - 4)

⇒(x -4) (x + 7)

Answer:

(x−4)(x+7)

You can now 800 square feet of lawn in 15 minutes at this rate how many minutes will it take you to mow a lawn that measures 600
frutty [35]
Ok so assuming you don't get tired and the rate stays the same
rate=amountwork/timeitdonein

rate=800/15

euals
6000/time

800/15=6000/time
simlify for ease
160/3=6000/time
multiply both sides by 3time
160time=18000
divide both sides by 160
time=112.5

means 112.5 minutes or 1hour, 52 minutes, 30 seconds

A. 800/15=6000/t or
15/800=t/6000

B. solved, 112.5 minutes

Find the probability that a Type A bulb lasts at least 300 hours and a Type B bulb lasts at least 400 hours.
barxatty [35]

Answer:

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

Step-by-step explanation:

We require more information by I will explain in principle:

If Type A has at least 300 hours and Type B at least 400 hours.

(X>3)(Y>4)=P(X>3)P(X>4)

You need to determine the Probability density function of X and Y and then subtract 1 from both

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

This will give you the probability of the expression.
