Two fair dice, one blue and one red, are tossed, and the up face on each die is recorded. Define the following events:
ZanzabumX [31]

Answer:

Step-by-step explanation:

Given that two fair dice, one blue and one red, are tossed, and the up face on each die is recorded.

a) P(E) = P(the difference of the numbers is 3 or more}

Favourable events are (1,4) (1,5)(1,6) (2,5) (2,6) (3,6) (4,1) (5,1) (5,2) (6,1) (6,2)(6,3)

P(E) = \frac{12}{36} =\frac{1}{3}

b)P(F)

Favourable events for F = (1,1) (2,2)...(6,6)

P(F) = \frac{6}{36} =\frac{1}{6}

c) P(EF)

There is no common element between E and F

P(EF) =0

a ball is tossed into the air from a height of 8 feet with an initial velocity of 8 feet per second. Find the time t(in seconds)
Nat2105 [25]
So first you need to factor and get 8( t-1 ) (2t+1)=0. Then you need to divide both sides by 8 to isolate the equation. 0/8=0 so ( t-1 ) (2t+1)=0. Next set each of the factors = to 0 and get t-1=0 and 2t+1=0. Solve, and get t=1 and t=-1/2. The negative does not apply so you know it takes 1 second for the ball to hit the ground.

Stella [2.4K]

The grocery mart offers the best deal on potato’s and price per pound is $0.03 less than Baldwin Hills market.

<em><u>Explanation</u></em>

At grocery mart, a  5 pounds bag of potatoes cost $2.85

So, <u>the unit price of potatoes per pound at grocery mart</u> =\frac{\$ 2.85}{5}=\$ 0.57

Now at Baldwin Hills market, 7 pounds bag of potatoes cost $4.20

So, <u>the unit price of potatoes per pound at Baldwin Hills market</u> =\frac{\$ 4.20}{7}=\$ 0.60

As \$0.57 , that means <u>the unit price of the potatoes per pound at grocery mart is less than the Baldwin Hills market</u>.

So, the grocery mart offers the best deal on potato’s.

The price of the potatoes per pound at grocery mart is (\$0.60-\$0.57)=\$0.03 less than the price at Baldwin Hills market.

Write 18 out of 100 as a fraction, as a percent, and as a decimal
raketka [301]

Answer:

Step-by-step explanation:

18/100

0.18

18%

Solve the following problem. Write 18% as a fraction in simplest form.

First, write the percent as a fraction out of 100.

18/100

Next, you simplify this fraction. The greatest common factor of 18 and 100 is 2, so you divide both the numerator and the denominator by 2.

18÷2/100÷2=950

Then, check to ensure that the fraction cannot not be reduced further. In this instance it cannot.

The answer is 18% can be written as the fraction 9/50 in simplest form.
