Raj wakes up in the morning and notices that his digital clock reads 07 2(A)5(B).After noon, he looks at the clock again.what is

Gre4nikov [31]

Answer:

i. $P(A) = \frac{1}{10}$

ii. $P(B) = \frac{1}{10}$

iii. $P(A) = \frac{3}{5}$

iv. $P(B) = \frac{2}{5}$

Step-by-step explanation:

Given

Time: 07 2(A) 5(B)

Calculating (a)

First, we need to list out the possible sample space, S of A

$S = \{0,1,2,3,....,9\}$

$n(S) = 10$

Probability of A being a 4 is the number of occurrence of 4 divided by the number of sample space

$A = \{4\}$

$n(A) = 1$

Hence;

$P(A) = \frac{n(A)}{n(S)}$

$P(A) = \frac{1}{10}$

Calculating (b)

First, we need to list out the possible sample space, S of B

$S = \{0,1,2,3,....,9\}$

$n(S) = 10$

Probability of B being a 8 is the number of occurrence of 8 divided by the number of sample space

$B = \{8\}$

$n(B) = 1$

Hence;

$P(B) = \frac{n(B)}{n(S)}$

$P(B) = \frac{1}{10}$

Calculating (c)

Using the sample space in (a)

$n(S) = 10$

Probability of A being less than 6 is the number of occurrence of less than 6 divided by the number of sample space

$A = \{0,1,2,3,4,5\}$

$n(A) = 6$

Hence;

$P(A) = \frac{n(A)}{n(S)}$

$P(A) = \frac{6}{10}$

$P(A) = \frac{3}{5}$

Calculating (d)

Using the sample space in (b)

$n(S) = 10$

Probability of B being greater than 5 is the number of occurrence of greater than 5 divided by the number of sample space

$B = \{6,7,8,9\}$

$n(B) = 4$

Hence;

$P(B) = \frac{n(B)}{n(S)}$

$P(B) = \frac{4}{10}$

$P(B) = \frac{2}{5}$

Tanya is going to Six Flags andplans to spend no more than $250.If the ticket cost $50 and foodaverages $4 per items, how manyfo

Vinvika [58]

ANSWER

50 food items

EXPLANATION

Tanya does not want to spend more than $250

The ticket costs $50 and each food item costs $4.

Let the number of items that can be bought be x.

So, the inequality that represents this situation is:

$50\text{ + 4x }\leq250$

Now, let us solve it:

$\begin{gathered} 4x\text{ }\leq\text{ 250 - 50} \\ 4x\text{ }\leq\text{ 200} \\ x\text{ }\leq\text{ }\frac{200}{4} \\ x\text{ }\leq\text{ 50} \end{gathered}$

Tanya can buy not more than 50 items.
