Answer:

A. True

Step-by-step explanation:

The empirical rule in statistics states that:

  • 68% of the data will be within 1 standard deviation
  • 95% of the data will be within 2 standard deviations
  • 99.7% of the data will be within 3 standard deviations

So yes, we can state that 5% or less of the data will be more than 2 standard deviations away from the mean. Of course, statistics is not 100% certain, so this rule is not 100% right all the time. Some exceptions might result, but generally speaking, the results should follow the empirical rule.

A line is perpendicular to y = {2/3x + 2/3}
Anna35 [415]

Answer: y = (-3x/2) + 1

Step-by-step explanation:

From the standard equation y = mx + c, the slope of the equation is 2/3. Therefor slope of a line perpendicular to it will be -3/2.

Hence the equation will be

y = (-3x/2) + c

As this line passes through (-2,4), putting these values in this equation gives  c = 1.

Hence the answer is y = (-3x/2) + 1

A triangle has side lengths of (8d – 3) centimeters, (6d + 2) centimeters, and
alisha [4.7K]

The perimeter of a triangle is the sum of its side lengths.

The perimeter of the triangle is: 14d + 7f +7

<u>The sides of the triangle are:</u>

Side 1 = (8d - 3) cm

Side 2 = (6d + 2) cm

Side 3 = (7f + 8) cm

The perimeter (P) is calculated as:

P = Side 1 + Side 2 + Side 3

So, we have:

P = (8d - 3) + (6d + 2) + (7f + 8)

Remove brackets

P = 8d - 3 + 6d + 2 + 7f + 8

Collect like terms

P = 8d  + 6d + 7f - 3 + 2 + 8

P = 14d + 7f +7

Hence, the perimeter of the triangle is: 14d + 7f +7
