make then have a common denominator first, so they would now be

32 3/4 12 2/4

now you can easily subtract the numerator and whole numbers (not demonitaor) to get the final answer of

20 1/4

Calculate the mean number of people per household.<br> 1,6,2,4,4,3,5,5,2,8

aliya0001 [1]

A mean is just another word for average. We get the average by adding up all the data number and dividing this sum by the number of data numbers there are.

So that list all added up is 40, and since there are 10 numbers, we divide 40 by 10, which gives us a mean of 4 people per household.

If two balanced dice are rolled, what is the probability that the sum of the two numbers that appear will be odd?

stiks02 [169]

The sample space for the experiment has a total of 36 possibilities.

Sample space for an odd sum is { 1,2 1,4 1,6 2,1 2,3 2,5 3,2 3,4 3,6 4,1 4,3 4,5 5,2 ,5,4 5,6 6,1 6,3 6,5 }

Probability = 18/36 = 1/2

Soy sauce is good to spice up a low salt diet. true false

Viefleur [7K]

<span>I think the correct answer would be false. Using soy sauce in order to spive up a low salt diet is not a good way. According to studies, one tablespoon of soy sauce usually has approximately 1000 mg of salt in it. Thus, it is a high sodium food.</span>

Find the equation of the line with the given properties. Passes through (4, -5) with a slope of -1\2

Setler [38]

$y=-\frac{1}{2}x-3$

Explanation

when you know the slope and a passing point of the line, you can find the equation of the line by replacing in the slope-point equation ,it is given by:

$\begin{gathered} y-y_1=m(x-x_1) \\ \text{where } \\ m\text{ is the slope} \\ \text{and} \\ (x_1,y_1)\text{ is a point from the line } \end{gathered}$

then

Step 1

a)Let

$\begin{gathered} \text{slope}=-\frac{1}{2} \\ \text{ Point=(4,-5)} \end{gathered}$

now,replace and solve for y

$\begin{gathered} y-y_1=m(x-x_1) \\ y-(-5)=-\frac{1}{2}(x-4) \\ y+5=-\frac{1}{2}x+\frac{4}{2} \\ y+5=-\frac{1}{2}x+2 \\ \text{subtract 5 in both sides} \\ y+5-5=-\frac{1}{2}x+2-5 \\ y=-\frac{1}{2}x-3 \end{gathered}$

therefore, the answer is

$y=-\frac{1}{2}x-3$

I hope this helps you

John runs the same amount each day (r). If he runs for 4 days this week write an expression to represent the amount he ran this

AnnyKZ [126]

Answer:

$r \cdot 4 = z$

Step-by-step explanation:

An expression means that we don't know enough to create an equation. So, this means we will mostly be using variables.

John runs r amount every day. We need to create an expression for if he runs r amount for 4 days.

$r \cdot 4 = z$

r = how much he runs per day

4 = how many days he runs

z = how much he runs this week

This is your expression!
