Y=50+.05x
Just plug in the number of texts for x
y=50+.05(25)
y=51.25
^That was for 25 texts
Now just plug in all the other texts and replace that with x
Hope this helps!
Answer:
And replacing we got:
And we can calculate this probabilit using the normal standard distribution or excel and we got:
Step-by-step explanation:
If we define the random variable of interest "the amount spent by a family of four of food per month" and we know the following parameter:
And we want to find the following probability:
And we can use the z score formula given by:
And replacing we got:
And we can calculate this probabilit using the normal standard distribution or excel and we got:
Answer:
The answer is 4/8=2/4 because 4/8 simplifying is 2/4 or 1/2
<span>y = -3x + 4
x + 1/3y = 4/3
Substitute the first expression into the second equation for y:
</span>x + 1/3(-3x + 4) = 4/3
x - x + 4/3 = 4/3
4/3 = 4/3
Answer;
All real numbers are solutions.
