Answer: There are 36 teachers total.
Step-by-step explanation:
Beacsue we know there are at least 30 teachers we need to change the fraction 3/18 becasue it is too simplified. So if we multiply the numerator and denominator by 2 we get 6/36. The new denominator is 36 which is the total amount of teachers.
Answer:
Step-by-step explanation:
The question is C=5(F-32)/9; For F
The best predicted value of y for x = 9.9 is y = 83.42.
<h3>What is linear equation if two variables?</h3>
Linear equations with two variables are equations with one, zero, or infinitely numerous solutions where every of a two variables has the highest exponential order of 1.
Some key features regarding linear equation if two variables are-
- The two-variable linear equation has the conventional form ax + by + c = 0, where x and y are the variables.
- These solutions might also be expressed in pairs, such as (x, y).
- A graphical representation of a linear equation system in two variables involves two straight lines that can be intersecting, parallel, or coincident.
Now, according to the question;
The given equation is;
y = 55.8 + 2.79x
Calculate the value of y by substituting the value of x = 9.9.
y = 55.8 + 2.79×9.9
y = 83.42
Therefore, the best predicted value of y for x = 9.9 is 83.42.

The correct question is-
Eight pairs of data yield r = 0.708 and the regression equation y = 55.8 + 2.79x. Also, the mean y-value is 71.125. What is the best predicted value of y for x = 9.9?
Answer:
y=mx+b
Step-by-step explanation: I believe this would be an equation that you can use for your points.
x≥ -2
Option C is correct.
Step-by-step explanation:
We need to identify which inequality is graphed below.
The graph starts with filled circle on -2 and move towards the right side of the line.
The value must be greater than or equal to -2 because the circle is filled.
So, x≥ -2
Option C is correct.
