Question:

You randomly draw a marble from a bag of marbles that contains 3 blue marbles, 4 green marbles, and 5 red marbles. What is P?

a) selecting a blue marble

b) selecting a green marble

c) selecting a red marble

Answer:

a) P(blue marble) = 1/4

b) P(green marble) = 1/3

c) P(red marble) = 5/12

Step-by-step explanation:

a) The probability of selecting a blue marble is given by,

P(blue marble) = no. of blue marbles/total no. of marbles

Where number of blue marbles = 3

Total number of marbles = 3 + 4 + 5 = 12

P(blue marble) = 3/12

P(blue marble) = 1/4

b) The probability of selecting a green marble is given by,

P(green marble) = no. of green marbles/total no. of marbles

Number of green marbles = 4

Total number of marbles = 12

P(green marble) = 4/12

P(green marble) = 1/3

c) The probability of selecting a red marble is given by,

P(red marble) = no. of red marbles/total no. of marbles

Where number of red marbles = 5

Total number of marbles = 12

P(red marble) = 5/12

So, the probabilities are

P(blue marble) = 1/4

P(green marble) = 1/3

P(red marble) = 5/12

Bas_tet [7]

Given:

Cory made 21 of the 60 baskets she attempted.

Krista made 16 out of 40 baskets she attempted.

Paul made 17 of the 50 baskets she attempted.

Sally 11 of the 55 she attempted.

To find:

Who had the greatest percentages of baskets made?

Solution:

We know that,

$\text{Percentage of baskets made}=\dfrac{\text{Baskets made}}{\text{Total attempts}}\times 100$

Using this formula, we get

$\text{Cory's percentage of baskets made}=\dfrac{21}{60}\times 100=35\%$

$\text{Krista's percentage of baskets made}=\dfrac{16}{40}\times 100=40\%$

$\text{Paul's percentage of baskets made}=\dfrac{17}{50}\times 100=34\%$

$\text{Sally's percentage of baskets made}=\dfrac{11}{55}\times 100=20\%$

From the above percentages 40% is maximum.

Therefore, Krista has greatest percentage of baskets made.

In the Founder's Day Parade in Happy, USA, many organizations participate by building floats. The Float Committee has issued a d

kolezko [41]

Answer:

$n = \frac{(427200 - 22250)}{178}$

Step-by-step explanation:

The Float Committee has issued a decree that each float can only have 427,200 flowers on it this year.

Now, the Happy Campers have already attached 22,250 flowers to their float.

Hence, there can be more (427200 - 22250) flowers added to the float.

If the flowers come in containers which hold 178 flowers, then the number of such containers to be used more will be $n = \frac{(427200 - 22250)}{178}$

So, this equation represents how many more containers they can use on their float. (Answer)
