Answer:

(a) 11.

(b) 5.

Step-by-step explanation:

(a)√124:

Find the value of x<br> DUE SUNDAY I NEED ASAP
Leto [7]

Answer:

x=43°

Step-by-step explanation:

The angles are adjacent and create a straight line so their sum is 180°.

(x+6)°+(3x+2)°=180°

x°+6°+3x°+2°=180°

4x°+8°=180°

4x°=172°

x=43°

A survey was taken of students in math classes to find out how many hours per day students spend
Hoochie [10]

Answer:

1. Mean, because there are no outliers that affect the center

Step-by-step explanation:

Second period: 3,2,3,1,3, 4, 2, 4, 3, 1, 0, 2, 3, 1, 2

Sorted values : 0, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4

The mean = ΣX / n

n = sample size, n = 15

Mean = 34 / 15 = 2.666

The median = 1/2(n+1)th term.

1/2(16)th term = 8th term.

The 8th term = 2

The best measure of centre is the mean because the values for the second period has no outliers that might have affected the centre of the distribution.

Both interquartile range and standard deviation are measures of spread and not measures of centre.

Answer:

  RS = √(b² +(c -a)²)

Step-by-step explanation:

Put the given point coordinates in the given formula:

  • R = (x₁, y₁) = (0, a)
  • S = (x₂, y₂) = (b, c)

  RS = √((b -0)² +(c -a)²)

  RS = √(b² +(c -a)²)
