Use the two frequency tables to compare the life expectancy of men and women from 20 randomly selected countries. Include an ove

rlayed frequency polygon (A.K.A.-line graph) and discuss the shapes of the distributions, the center, the spread, and any outliers. What can we conclude about the life expectancy of women compared to men?

Answer:

<em>conclusion : Life expectancy of women > Life expectancy of men </em>

Step-by-step explanation:

A) Mean life expectancy of women

from the attached table

mean life expectancy of women = ∑fx / ∑f

∑fx = 1523

∑f = 20

mean = 1523 / 20 = 76.15

The line graph shows a negatively skewed distribution

B) Mean life expectancy of Men

from the attached table

mean life expectancy of Men = ∑fx / ∑f

∑fx = 1432

∑f = 20

mean = 1432 / 20 = 71.6

<em>conclusion : Life expectancy of women > Life expectancy of men </em>

When a number is divided by 5 the answer is 3 remainder 4, what is that number?
skelet666 [1.2K]

We know that 5 fits entirely into our number three times, and then there's a remainder of 4.

If 5 fits three times exactly, it means that our number is at least 15 (5x3).

From here, we have a remainder of 4, which leads to 15+4=19

A bouncing ball reaches a height of 54 inches at its first peak, 36 inches at its second peak, and 24 inches at its third peak.
steposvetlana [31]
54, 36, 24 are the 1st 3 element of a geometric progression with 2/3 as a common ratio: PROOF:
the 1st term is 54, (a₁= 54) the 2nd term a₂ = 24, then
(a₂ = a₁.r) or 36 = 54.r → r= 36/54 = 2/3. Same logique for the 3rd term. 
So 2/3 is common ratio. We know that :U(n) = a.(r)ⁿ⁻¹. Then if a =54 and r = x (given by the problem), then f(x) = 54.xⁿ⁻¹
n, being the rank of any element of this geometric progression

JONAS HAS A FILE CABINET IN THE SHAPE OF A right rectangular prism. the area of the base of the file cabinet is 450 square inche
Nostrana [21]
The volume of a rectangular prism can be found by the formula:
V = A × h

Where:
A = area of the base of the prism
h = height of the prism

Therefore:
V = 450 × 53 
   = 23850 in³

The volume of the file cabinet is <span>23850 in³.</span>

Type the correct answer in the box. Round your answer to the thousandth place.
kupik [55]

Answer:

<u>The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is 19.338% (Rounding to the next thousandth place)</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Probability that carbon emissions from the company’s factory exceed the permissible level = 35% = 0.35

Accuracy of the test of emissions level = 85% = 0.85

2. The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is?

These two events, carbon emissions from the company’s factory and the accuracy of the test are independent events, therefore:

Probability that carbon emissions from the factory are within the permissible level = 1 - 0.35 = 0.65

Probability that the test predicts the opposite to be true = 0..35 * 0.85 = 0.2975 (The opposite is that the carbon emissions from the company exceed the permissible level)

Probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is:

0.65 * 0.2975 = 0.193375

<u>The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is 19.338% (Rounding to the next thousandth place)</u>
