The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 13.1 years; the standard devia

Ilia_Sergeevich [38]

Answer:

The probability between 16.1 and 17.6 years = 0.0214 years

The Estimate probability between 16.1 and 17.6 years = 2.14 years

Step-by-step explanation:

Step(i):-

Given the average of Population 13.1 years

The standard deviation of the Population = 1.5 years

Let 'x' be the random variable in Normal distribution

Given x = 16.1

$Z _{1} = \frac{x- mean}{S.D}$

$=\frac{16.1-13.1}{1.5}$

= 2

Z₁ = 2

Step(ii):-

Given x = 17.6

$Z_{2} = \frac{17.6- 13.1}{1.5}$

Z ₂= 3

Z₁ = 2 and Z ₂= 3 are both positive

The Estimate probability between 16.1 and 17.6 years

P( 16.1<x<17.6) = P( 2 < Z < 3)

= A(3) - A(2)

= 0.49865 - 0.4772 (from normal table)

= 0.0214

The probability between 16.1 and 17.6 years = 0.0214 years

= 0.0214 ×100

= 2.14 years

Final answer:-

The Estimate probability between 16.1 and 17.6 years = 2.14 years

PLEASE HELP !!!

<h3>Answer: D. 80% of the home’s value</h3>

============================================================

Explanation:

As you probably expect, the first number 80 refers to the percentage the first loan covers. If the house is say $100,000, then the first loan is $80,000 while the second loan is the remaining $20,000.

An 80/20 mortgage, or similar, will have two monthly payments because you are getting two mortgages bundled together. Usually you should pay a down payment, though it may likely depend on your credit history. Those with good credit will pay less or no down payment, compared to those with worse credit will have to pay more down payment. A good rule of thumb is that 20% of the home's value is made as down payment, though this isn't what the "20" in "80/20" is referring to.

An 80% down payment is extremely high and unreasonable. Not many people have that kind of money laying around. A similar story applies to a 20% interest rate which is incredibly large for a mortgage rate (typically they are in the single digits such as 3%).

Can someone please help me

zloy xaker [14]

Answer:

see explanation

Step-by-step explanation:

(a)

9n = $\frac{15}{7}$ - 2 ( multiply through by 7 to clear the fraction )

63n = 15 - 14 = 1 ( divide both sides by 63 )

n = $\frac{1}{63}$

(b)

$\frac{1}{3}$ = k - 4 ( multiply through by 3 to clear the fraction )

1 = 3k - 12 ( add 12 to both sides )

13 = 3k ( divide both sides by 3 )

$\frac{13}{3}$ = k

(c)

g - $\frac{2}{5}$ g = 3 ( multiply through by 5 to clear the fraction )

5g - 2g = 15

3g = 15 ( divide both sides by 3 )

g = 5

(d)

$\frac{3}{7}$ w + 2w = 3 ( multiply through by 7 to clear the fraction )

3w + 14w = 21

17w = 21 ( divide both sides by 17 )

w = $\frac{21}{17}$

What is the approximate volume of a cone with a height of 9 ft and radius of 3 ft?

tensa zangetsu [6.8K]

Volume of a cone=1/3 times height times area of base
area of base=area of circle=pi times r^2
r=3
aprox pi to 3.14
height=9

so we have
volume=1/3 times 9 times 3.14 times 3^2
3^2=9
1/3 times 9 times 3.14 times 9
3 times 3.14 time s9
9.42 times 9
84.78
nearest tenth
0.78=0.8

answer is 84.8 ft^3
