In all, 1000 students took a statistics exam worth 150 points. The first quartile (or Q1) for all 1000 scores is 90 points. Abou
Brums [2.3K]

Answer:

The number of students who scored more than 90 points is 750.

Step-by-step explanation:

Quartiles are statistical measures that the divide the data into four groups.

The first quartile (Q₁) indicates that 25% of the observation are less than or equal to Q₁.

The second quartile (Q₂) indicates that 50% of the observation are less than or equal to Q₂.

The third quartile (Q₃) indicates that 75% of the observation are less than or equal to Q₃.

It is provided that the first quartile is at 90 points.

That is, P (X ≤ 90) = 0.25.

The probability that a student scores more than 90 points is:

P (X > 90) = 1 - P (X ≤ 90)

                = 1 - 0.25

                = 0.75

The number of students who scored more than 90 points is: 1000 × 0.75 = 750.

Y=-3+1/2x
yarga [219]

Answer:

(2, - 2 )

Step-by-step explanation:

y = - 3 + \frac{1}{2} x → (1)

3x + 2y = 2 → (2)

Substitute y = - 3 + \frac{1}{2} x into (2)

3x + 2(- 3 + \frac{1}{2} x) = 2 ← distribute parenthesis and simplify left side

3x - 6 + x = 2

4x - 6 = 2 ( add 6 to both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Substitute x = 2 into (1)

y = - 3 + \frac{1}{2} (2) = - 3 + 1 = - 2

solution is (2, - 2 )
