Answer:

C. x - 4

Step-by-step explanation:

f(x) = 3x - 6

g(x) = 2x - 2

To find f(x) - g(x), we'll substitute these 2 functions with their definitions above.

f(x) - g(x)

Putting in f(x):

(3x-6) - g(x)

Putting in g(x):

(3x-6) - (2x-2)

Expanding the parenthesis, we see that - (2x-2) becomes -2x + 2

The positive, 2x, becomes negative. The negative, -2, becomes positive.

3x - 6 - 2x + 2

Now just moving the x-terms together:

3x - 2x - 6 + 2

Since 3x-2x = x

x - 6 + 2

Since -6 + 2 = -4

x - 4

Answer: x - 4

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 13.113.113, point, 1 years; th
skad [1K]

Answer:

The Probability = 0.16

Step-by-step explanation:

Empirical rule formula states that:

68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

Average = 13.1 years

Standard deviation = 1.5 years

x = 14.6 years

= 14.6 -13.1/1.5

= 1

This falls within 1 standard deviations of the mean

68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

Hence:

100 - 68%/2 = 32/2 = 16%

Converting to probability = 0.16

The probability of a meerkat living longer than 14.6 years is 0.16

Rashid [163]
She added the numerators
instead of multiplying them

you should also simplify the final answer

the correct answer would be -3 1/8 or -25/8 as an improper fraction.
