pshichka [43]
We know that

red marbies=3------> r=3
green marbies=4----> g=4
blue marbies=3-----> b=3
total marbles in the bag=r+g+b-----> 3+4+3-----> 10

a) <span>probability of randomly selecting a green (g) marble
P(green)=g/total marbles------> 4/10-----> 2/5

b) </span>probability of randomly selecting a red (r) marble
the marble is replaced so we have the same total marbles
P(red)=r/total marbles------> 3/10

c) <span>Total probability of selecting this path is:
P(green)*P(red)-----> (2/5)*(3/10)-----> 6/50----> 3/25----> 0.12  (12%)

the answer is
0.12  (12%)</span>

Taisha is making birthday gift bags. she wants to put 1/2 pound of chocolate in each bag. she has 4 3/4 pounds of chocolate. how
Varvara68 [4.7K]

Taisha is making gift bags for birthday. She intends to fill each bag with ½ pound of chocolate. Her chocolate bag weighs 4 ¾ pounds. Taisha can make 9.5 gift bags for the birthday.

This is calculated as,

There are 4 ¾  pounds of chocolate. 

Each bag will have ½  pound of chocolate. 

½ pound × Gift bags = 4 ¾ pounds.

4 ¾ pounds ÷ ½ pound = Gift bags.

4 ¾ pounds is 4.75 pounds and ½ pound is 0.5 pounds.

4.75 pounds ÷ 0.5 pound = 9.5 bags. 

Hence , Taisha could make 9.5 gift bags for the birthday.

AveGali [126]

Answer:

C

Step-by-step explanation:

The distance around the circle is asking for the circumference of the circle.

Since we know that the diameter is 21 and the equation for the circumference of a circle is 2*pi*r and since 2*r is just the diameter, we can say that the circumference is 21*pi, which would be C.
