How Would Youdescribe Thefollowing Events, Ofrandomly Rolling 2dice And Having Asum That Is EVEN ORGREATER

Answers

Answer 1

The probability of the given event randomly rolling two dice and having a sum that is even or greater than 9 is 2/3.

As given,

Let us assume X is the event of the sum of two dice is even

Therefore

P(X) = The probability of having an even sum of two dice

Since all events are given in the question image, then

n(S) = Sample space = 36

X = {(1,1) , (1,3), (1,5), (2,2), (2,4), (2,6), (3,1), (3,3), (3,5), (4,2), (4,4), (4,6), (5,1), (5,3), (5,5), (6,2), (6,4), (6,6)}

n(X) = 18

Since

P(X) = n(A)/n(S)

P(X) = 18/36

P(X) = 1/2

Let us assume Y is the event of the sum of two dice is greater than 9, then

Y = {(4,6), (5,5), (5,6), (6,4), (6,5), (6,6)}

n(Y) 6

P(Y) = n(Y)/n(S)

P(Y) = 6/36

P(Y) = 1/6

P(X∪Y) = P(A) + P(B)

= 1/2 + 1/6

= 4/6

= 2/3

Therefore,  probability of the given event randomly rolling two dice and having a sum that is even or greater than 9 is 2/3.

The table shows the cost of shampoo at a discount store Cost $ 2.95 $4.50 $6.05 Number of bottles 1 2 3is the cost of the shampoo bottles proportional to the amount of bottles ?

Answers

Answer:

Not proportional

Explanation:

First, we determine the unit rate for each of the pairs of points.

[tex]\begin{gathered} UnitRate=\frac{\text{Cost}}{\text{Number of bottles}} \\ \frac{2.95}{1}=\$2.95\text{ per bottle} \\ \frac{4.50}{2}=\$2.25\text{ per bottle} \\ \frac{6.05}{3}=\$2.02\text{ per bottle} \end{gathered}[/tex]

We see that the unit rates are not the same.

Therefore, the cost of the shampoo bottles IS NOT proportional to the number of bottles

107/56 is the solution of fractions .

What do math fractions mean?

An element of a whole is a fraction. In mathematics, the number is represented as a quotient, where the numerator and denominator are divided. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction.

The given fractions are 5/8 and 1 2/7.

We need to find the sum of given fractions.

Now, we can write 1 2/7 as 9/7.

So, 5/8 + 9/7

Here, LCM of 8 and 7 is 56

Then, 35/56 + 72/56

=(35+72)/56

=107/56

Therefore, the sum of the two given fractions is 107/56.

Step 1:

Write the formula connecting y and x.

After 4 months of a new nutrition program rashid has lost 16% of his original weight he lost 36lb what was rashids original weight?

Answers

Rashids original weight based on the information illustrated is 225lb.

What was the original weight?

From the information given, after the nutrition program rashid has lost 16% of his original weight he lost 36lb.

Let the original weight be given as x.

Therefore, 16% × x = 36

0.16x = 36

Divide through by 0.16

0.16x / 0.16 = 36 / 16

x = 36/0.16

x = 225lb

The weight is 225lb.

What is the Function :

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

So,

We can write,

One input value has more than output values.

In this function we have,

-1 is mapped to both -2 and -1

In this case,

-1 input value is mapped to both output values of -2 and -1.

Therefore,

No, because there is an input values with more than one output value is the following relation a function.

Her classmate, Marie, has passed 3 tests of them. From now on, Rebecca plans to take and pass 2 tests per week. Meanwhile, Marie plans to do 5 per week. At some point, Rebecca will catch up to Marie. How long will it take? How many tests will each child have passed? In weeks, the children will each have passed tests.

Answers

Solution

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Represent the unknown terms

Let x represents the number of weeks

Let y represents the total number of test passed

STEP 2: Interpret the statements

For Rebecca

[tex]y=2x+12[/tex]

For Marie

[tex]y=5x+3[/tex]

STEP 2: Find the number of weeks they will pass the same amount of test.

This means that y will be equal to y

[tex]\begin{gathered} y=y \\ 2x+12=5x+3 \\ 2x-5x=3-12 \\ -3x=-9 \\ x=\frac{-9}{-3}=3\text{ weeks} \end{gathered}[/tex]

Given that the pharmacist can fill 250 prescriptions in 40 hours.

Consider the following,

So it can be understood that the pharmacist can fill 250 prescriptions in 2400 minutes.

Then the time taken to fill 1 prescription is calculated as,
