x ≤ a → x ∈ (-∞, a]

x < a → x ∈ (-∞, a)

x ≥ a → x ∈ [a, ∞)

x < a → x ∈ (a, ∞)

--------------------------------------

Therefore:

x ≥ 7.8 → [7.8, ∞)

x < 7.8 → (-∞, 7.8)

x ≤ 7.8 → (-∞, 7.8]

x > 7.8 → (7.8, ∞)

Using the line of the best fit, the predicted student's score in English test is 48

<h3>How to determine the student's score in English?</h3>

From the question, we have:

Mathematics score = 60

The scores in English tests are plotted on the y-axis.

On the given graph, we have:

(x,y) = (60,48)

This means that when x = 60, the value of y is 48

This in other words means that the student's score in English test is 48

Suppose that during one period extreme cold,the average daily temperature decreased 1 1/2 F each day. How many days did it take
Alenkasestr [34]

We have been given that during one period extreme cold, the average daily temperature decreased 1\frac{1}{2} degree F each day. We are asked to find number of days it will take for the temperature to decrease by 9 degree F.

First of all we will convert our mixed fraction into improper fraction.

1\frac{1}{2}=\frac{3}{2}

Now we will divide total temperature change (9) by average daily temperature change (\frac{3}{2}) to find number of days.

9\div\frac{3}{2}

Dividing a number by a fraction is same as multiplying the number by reciprocal of the fraction.

9\cdot\frac{2}{3}

3\cdot2=6

Therefore, it will take 6 days for the temperature to decrease by 9 degree F.
