An acre measures 4840 square yards. In a city a lot on which a single family house can be built measures 40 feet across and 100

maw [93]

We are required to find the percent of an acres is this lot

The percent of acres of the lot is 27.55%

Area of an acre = 4840 square yards

Area of the lot = Length × width

= 40 feet × 100 feet

= 4000 square feet

<em>convert feet to yards</em>

1 foot = 0.333333

4000 square feet = 1333.333 square yards

Therefore,

Area of the lot = 1333.333 square yards

percent of an acres is this lot = 1333.333 / 4840 × 100

= 0.2754820247933 × 100

= 27.548202479338

Approximately,

27.55%

Therefore,

The percent of acres of the lot is 27.55%

Question Help A manufacturer ships toasters in cartons of 1010. In each carton, they estimate a 1010% chance that any one of t

natta225 [31]

Answer:

The probability that there will be repair exactly 3 toaster is 0.0574.

Step-by-step explanation:

Binomial Distribution:

A discrete random variable X having the set {0,1,2,3......,n} as the spectrum, is said have a binomial distribution with parameter n= number of trials and p=probability of number of success on an individual trial, if the p.m.f (probability mass function) of X given by,

$P(X=x)=C(n,x)p^x(1-p)^{n-x}$ x=0,1,2,......,n

=0 elsewhere

where 0<p<1 and n is a positive integer.

Total number of toaster in cartons(n) = 10.

Probability of number of success on an individual trial p= 10% = 0.10

$\therefore P(X=3)= C(10,3)(0.10)^3(1-0.10)^{10-3}$

$=\frac{10!}{3!(10-3)!}(0.10)^3)(0.90)^7$

=0.0574

The probability that there will be repair exactly 3 toaster is 0.0574.

I have a stamp collection. 70% of my stamps are Canadian and 30% are international. I have 500 more Canadian stamps than interna

shutvik [7]

Answer: N= 375, C= 875

Step-by-step explanation: Let Canadian stamps=C

Let International stamps=N

C=875 and N=375

C - 500=N, .70(N + C) =C

Solve the following system:

{C-500 = N | (equation 1)

0.7 (C+N) = C | (equation 2)

Express the system in standard form:

{-N+C = 500 | (equation 1)

0.7 N-0.3 C = 0 | (equation 2)

Add 0.7 × (equation 1) to equation 2:

{-N+C = 500 | (equation 1)

0 N+0.4 C = 350 | (equation 2)

Divide equation 2 by 0.4:

{-N+C = 500 | (equation 1)

0. N+C = 875. | (equation 2)

Subtract equation 2 from equation 1:

{-N+0 C = -375. | (equation 1)

0 N+C = 875. | (equation 2)

Multiply equation 1 by -1:

{N+0 C = 375. | (equation 1)

0 N+C = 875. | (equation 2)

Collect results:

Answer: | N = 375 and C=875

0.3(n-5)=0.4-0.2 solve for n!

mariarad [96]

Answer:

$n = 5.67$

Step-by-step explanation:

0.3(n-5)=0.4-0.2

0.3(n-5) = 0.2

Dividing 0.3 both side

$\frac{0.3(n-5) }{0.3} = \frac{0.2}{0.3}$

$n-5 = 0.67$

$n = 0.67+5$

$n = 5.67$
