Simplify the product using FOIL (2x-7)(5x+5)

Mathematics
1 answer:
babunello [35]4 years ago
7 0

Answer:

10x^2-25x-35

Step-by-step explanation:

FOIL means first, outer, inner, and last.

The first term of each pair is 2x and 5x.

The outer term of each pair is 2x and 5.

The inner term of each pairs are -7 and 5x.

The last term of each is -7 and 5.

Now we just have to multiply the terms I pairs above:

First:   (2x)(5x)=10x^2

Outer: (2x)(5)=10x

Inner: (-7)(5x)=-35x

Last:   (-7)(5)=-35

------------------------------Add the terms:

10x^2-25x-35

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.410.410, point, 4 years; th
Neko [114]

Answer:

99.7%

Step-by-step explanation:

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.4 years; the standard deviation is 1.9 years.

Use the empirical rule (68−95−99.7%) to estimate the probability of a meerkat living between 4.7 years and 16.1 years

The empirical rule states that almost all data fall within three standard deviations of the mean for a normal distribution. These are:

  1. 68% of data falls within the first standard deviation from the mean ( μ ± σ)
  2. 95% fall within two standard deviations ( μ ± 2σ)
  3. 99.7% fall within three standard deviations( μ ± 3σ)

Given that:

mean (μ) = 10.4 years and standard deviation σ = 1.9 years

The first standard deviation ( μ ± σ) = (10.4 ± 1.9) = (8.5, 12,4). Therefore, 68% of data falls between 8.5 years and 12.4 years

The second standard deviation ( μ ± 2σ) = (10.4 ± 2×1.9) = (6.6, 14.2). Therefore, 95% of data falls between 6.6 years and 14.2 years

The third standard deviation ( μ ± 3σ) = (10.4 ± 3×1.9) = (4.7, 16.1). Therefore, 99.7% of data falls between 4.7 years and 16.1 years
