Mathematics

UNO [17]4 years ago

Answer:

Step-by-step explanation:

Normally Z scores in a std normal distribution curve lie between -3 and 3 comprising more than 99% of total area.

Any entry outside (-3,3) can be considered as an extreme observation.

Here we have hence a) -4.3 is the most extreme observation.

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

Given that 84 separates the lowest 75% of the scores from the highest 25% of the scores,

This means 84 is the 75th percentile and similarly 65 is the 25th percentile.

Thus we have 84 has the percentile rank of 75

Answer:

\frac{8}{9}

Step-by-step explanation:

we require 2 equations with the repeating digits placed after the decimal point.

let x = 0.888.. (1) ← multiply both sides by 10

10x = 8.888.. (2)

subtract (1) from (2) thus eliminating the repeating digits

9x = 8 ( divide both sides by 9 )

x = \frac{8}{9}

If L ll M, classify the marked angle pair and give their relationship, then solve for x
Talja [164]

Answer:

Supplementary angle; x = 14.

Step-by-step explanation:

Angle (9x - 2) and angle (10y + 6) form a straight line, so they form a supplementary angle.

Because angle (9x - 2) and (5x + 54) are corresponding angles, we can set them equal to each other.

9x - 2 = 5x + 54

9x - 5x = 54 + 2

4x = 56

x = 14.

Hope this helps!
