wildflower mix contains several different types of seeds.

cornflower 40
primrose 3
black-eyed Susan 2
poppy 6
baby's breath 12

What is the probability that a randomly selected seed will be a poppy seed?

Answer:

Given:

⇒ P(black ball) = 3/10 = 0.3

⇒ P(white ball) = 7/10 = 0.7

If one ball is chosen at random and replaced, the probabilities do not change between the first and second ball.

Let event D = first ball is black

Let event S = second ball is black

P(D) = 0.3

P(S) = 0.3  (since the first ball is replaced)

⇒ P(D ∩ S) = P(D) × P(S)

                   = 0.3 × 0.3

                   = 0.09

For Independent Events we know that:  P(A ∩ B) = P(A) × P(B)

Therefore, as P(D ∩ S) = P(D) × P(S) the events are independent.

The number of rectangular prism container that would be set on the shelf is: 4.

Volume of rectangular prism = length × width ×height

Given the following:

Find the length of one rectangular prism using the volume formula since volume for one prism = 45 in.³

45 = length × 9

length = 5 in.

Each rectangular prism container is 5 in. long, therefore, the number of the containers that can be set on the shelf that is 24 in. long, if the 4.5 in by 2 in. face touches each other = 24/5 = 4.8.

The fifth container won't fit in. Therefore, the number of rectangular prism container that would be set on the shelf is: 4.

Answer:

Lets break this down

The question asks for “How many balloons does she end up with”?

A important fact is that Jan doesn’t care what color she has.
So using this we can disregard the colors.

She is only allowed to have 60 percent of all the balloons she choosed.

So lets add them.

10 + 12 +8 + 9 = 39

She chose 39 balloons in total.
Since she doesn’t care about the color we can jsut find 60 percent of 39.

In order to find this we just multiply 60% of 39.

Percentage means out of a hundred so 60 percent is 60 out of a hundred or in this age 60/100.

Now 60/100 is basically 0.6

So we multiply 39 by 0.6

23.4 is the answer.

Now you can’t have .4 of a balloon so we jsut round down for any decimal in this case.

23.4 is 23 now.

So 23 balloons is the amount of balloons Jan ends up with

The conversion of area units results in:

For converting units of area, it is necessary to know the conversion factors and relate the units. For the units of area,  each unit is 100 times larger than the previous. See below the relationship between the meter and the other units

1km²=1 000 000 m²=[tex]10^6[/tex] m²

1 hm²= 10 000 m²= [tex]10^4[/tex] m²

1 dam²=100 m²= 10² m²

1 m² =1 m²= 1 m²

1 dm²=0.01 m²= [tex]10^{-2}[/tex] m²

1 mm²=0.000001 m²= [tex]10^{-6}[/tex] m²

Now, you have the necessary information for converting the units.

        [tex]1 cm^2 =10^{-4}m^2\\ 230000= x\\ \\ x= 230000 * 10^{-4}\\ \\ x=23 \;m^2[/tex]

       [tex]1 cm^2 =10^{-4}m^2\\ 400000= x\\ \\ x= 400000* 10^{-4}\\ \\ x=40\;m^2[/tex]

      [tex]1 cm^2 =10^{-4}m^2\\ 60000= x\\ \\ x= 60000* 10^{-4}\\ \\ x=6\;m^2[/tex]

         [tex]1 cm^2 =10^{-4}m^2\\ x= 15 \\ \\ 10^{-4}x= 15\\ \\ x=15*10^4\\ \\x= 150\;000\;cm^2[/tex]

         [tex]1 cm^2 =10^{-4}m^2\\ x= 120\\ \\ 10^{-4}x= 120\\ \\ x=120*10^4\\ \\x= 1\;200\;000\;cm^2[/tex]

         [tex]1 cm^2 =10^{-4}m^2\\ x= 16\\ \\ 10^{-4}x= 16\\ \\ x=16*10^4\\ \\x= 160\;000\;cm^2[/tex]

Answer:

14.01 and 107

Step-by-step explanation:

First let’s review what all the crodile mouths mean:

< = # is less than the # on the right

> = # is more than the # on the right

≤ = # less than or equal to # on the right

≥ = # is greater than or equal to # on right

Equation:

y ≥ 14

To make this true on the values that are greater than or equal to 14 can go.

This means that these values would be correct out of the options:

14.01

107

Furthermore, 13 and 10 don’t make the equation true because neither are greater than or equal to the value 14.
