Answer: 300
Step-by-step explanation:
Let the total number of people surveyed be represented by x.
Since we are informed that the probability of a customer ordering chicken is 1/4 and 75 people said they prefer to order chicken. This will then be:
1/4 of x = 75
1/4 × x = 75
x = 75 × 4
= 300
Therefore, 300 people were surveyed

Step-by-step explanation:
Answer:
3/4
Step-by-step explanation:
Start from the y-intercept (-1). Find another point that is on the line. I am using the point (0, -1) and also (4, 2).
Next, use the slope form, rise over run. In this case, you can also use the formula (y² - y¹) / (x² - x¹).
Plug in the values, and you get 3/4. So, the slope is 3/4.
Also, you can count from one point of the line up and to the right in this problem to find the slope.
![\log(9)=\log_{10}(9)=\dfrac{\log_{5}(9)}{\log_{5}(10)}](https://tex.z-dn.net/?f=%5Clog%289%29%3D%5Clog_%7B10%7D%289%29%3D%5Cdfrac%7B%5Clog_%7B5%7D%289%29%7D%7B%5Clog_%7B5%7D%2810%29%7D)
In my opinion, that is the simplest form. However, your teacher may want you to remove powers and factors of 5. In that case, the result is ...
We know that
<span>a) the slope-intercept form of the line---------------> y=mx+b
b) </span><span>if two lines are parallel both have the same slope
</span>then
<span>passes through the point (1,0) and is parallel to x-y=7
Step 1
Find the slope
</span>x-y=7------------> y=x-7------------> m=1
Step 2
Find the slope-intercept form of the line---> y=mx+b
point (1,0) m=1
0=(1)*(1)+b------> b=-1
y=(1)*x-1--------> y=x-1
the answer is
y=x-1
