Domain: All Real Numbers

Range: All Real Numbers

Further explanation:

Let us define domain and range first

Domain is the set of all possible inputs for a function on which the function is defined.

While range is the output of the function obtained by inputting domain

Here,

Given function is:

$f(x) =x-3$

The function will not be undefined on any input, so the domain of the function is all real numbers.

Similarly, the range will also be all real numbers as there is no input which makes it undefined.

When the dice is rolled 14 times then from the given data the probability of 1,2,3,4,5,6 is 3/14,1/14,4/14,1/14,3/14,2,14.

Given Roll of dice and outcomes from 1 to 14 is 1,3,5,4,5,3,3,1,3,5,6,1,6,2.

From the given collected data we can find out number of times each number came when the dice is rolled.

Number of times 1 came=3

Number of times 2 came=1

Number of times 3 came=4

Number of times 4 came=1

Number of times 5 came=3

Number of times 6 came=2

The probabilities are in fraction form:

P(1)=3/14

P(2)=1/14

P(3)=4/14

P(4)=1/14

P(5)=3/14

P(6)=2/14

The probabilities in decimal form:

P(1)=0.21

P(2)=0.07

P(3)=0.28

P(4)=0.07

P(5)=0.21

P(6)=0.14

The probabilities in percentage:

P(1)=21%

P(2)=7%

P(3)=28%

P(4)=7%

P(5)=21%

P(6)=14%

Hence the probabilities are 3/14,1/14,4/14,1/14,3/14,2,14.

I don't really need the answer I just want to understand how to get the answer.

You use the rules of BEDMAS so start with the brackets -[2(-17)] start with 2*-17 which is -34 then multiply -4*-5=20 so now you have 20-(-17)=37 butttt the question is asking to SIMPLIFY so you combine like terms which adds up to 37

Mona has invested $2840 in a savings account for 6 years. She earned $894.60 in a simple interest. What was the annual interest

forsale [732]

Answer:

The annual interest rate was 5.25%.

Step-by-step explanation:

Simple interest can be calculated using the following formula: I = PRT, where I=simple interest, P=principal amount, R=percentage rate and T=time. In this problem, Mona started with a principal amount of $2840, or P=2840 and invested for 6 years, or T=6, to gain simple interest in the amount of $894.60, or I=894.60. When we put in the values for our variables in the equation, we get: 894.60 = (2840)(6)R. Multiplying 2840 x 6 = 17040 and gives us: 894.60 = 17040R. Using inverse operations to isolate the variable, we divide both sides by 17040 to get R=0.0525. Since the rate is a percentage, we need to multiply our answer by 100 to get 5.25%.
