A number is randomly selected from {1, 2, 3, 4, 5, 6, 7, 8, 9, 10).

Katyanochek1 [597]

In this case, the complement would be selecting a number less than or equal to 7; the probability of this occurring is $\boxed{\frac{7}{10}}.$

What are the domain and range of the function {(5, 3), (7, 1), (11, –2), (4, 9), (–2, 4)}?

natita [175]

Answer is C. Set of first part of the binary set is domain and second part of it is range. So the domain will be {5, 7, 11, 4, –2} and the range will be {3, 1, –2, 9, 4}

nlexa [21]

Answer:

448 cubes

Step-by-step explanation:

Volume of cubes fitted in the box will be equal to the cumulative volume of the cubes.

Since, volume of a cube = (Side)³

Side of the cube = $\frac{1}{2}$ inch

Therefore, volume of the cube = $(\frac{1}{2})^3=\frac{1}{8}$ inches

Volume of the storage box = 56 cubic inches

Since, number of cubes fitted in the storage box = $\frac{\text{Volume of the storage box}}{\text{Volume of one cube}}$

= $\frac{56}{\frac{1}{8}}$

= 56 × 8

= 448 cubes

Therefore, number of cubes fitted in the storage box = 448

SSSSS [86.1K]

Answer: 0.375

Step-by-step explanation:

Let G be the event that the chosen marble is green. Let $B_i$ be the event that we choose Box i.

The probabilities of choosing a box are :

$P(B_1)=\dfrac{1}{40}=0.25\\\\P(B_2)=\dfrac{1}{2}=0.5\\\\P(B_3)=\dfrac{1}{4}=0.25$

Now, $P(G|B_1)=\dfrac{5}{10}=0.5$

$P(G|B_2)=\dfrac{3}{10}=0.3$

$P(G|B_1)=\dfrac{4}{10}=0.4$

By using the law of total probability, we have

$P(G)=P(G|B_1)P(B_1)+P(G|B_2)P(B_2)+P(G|B_3)P(B_3)\\\\\Rightarrow\ P(G)=0.25\cdot0.5+0.5\cdot0.3+0.25\cdot0.4=0.375$
