Can someone help me and do this for me were doing convert customary units if lenght
Mamont248 [21]

Well there are 5280 feet in 1 mile and if you multiply that by 2 then that's too many. if you multiply 5280 by 1.5, then you get 7920 so it is equal to 1.5 miles.

There are 36 inches in 1 yard so you multiply 6 by 36 to get 216.

Again there are 5,280 feet in 1 mile. Divide 26,400 by 5,280 and you get 50 miles.

12 inches in 1 foot. Multiply 12 by 9 and get 144.

22 feet equals 7 yards and 1 foot.

51 inches equals 4 feet and 3 inches. (4 feet equals 48 inches)

Btw, 7 yards is greater then 20 feet (7 yards equals 21 feet)

2 miles is more then 3,500 yards. (2 miles equals 2,520 yards)

11.5 feet is less then 4 yards (4 yards equals 12 feet)

72 inches is EQUAL to 2 yards

5.5 yards is more then 192 inches.  (5.5 yards equals 198 inches)

Suppose N has a geometric distribution with parameter p. Derive a closed-form expression for E(N | N &lt;= k), k = 1,2,... Check
vfiekz [6]

Answer:

P(X= k) = (1-p)^k-1.p

Step-by-step explanation:

Given that the number of trials is

N < = k, the geometric distribution gives the probability that there are k-1 trials that result in failure(F) before the success(S) at the kth trials.

Given p = success,

1 - p = failure

Hence the distribution is described as: Pr ( FFFF.....FS)

Pr(X= k) = (1-p)(1-p)(1-p)....(1-p)p

Pr((X=k) = (1 - p)^ (k-1) .p

Since N<=k

Pr (X =k) = p(1-p)^k-1, k= 1,2,...k

0, elsewhere

If the probability is defined for Y, the number of failure before a success

Pr (Y= k) = p(1-p)^y......k= 0,1,2,3

0, elsewhere.

Given p= 0.2, k= 3,

P(X= 3) =( 0.2) × (1 - 0.2)²

P(X=3) = 0.128

A nature center offers 2 guided walks. The morning walk is two-third mile. The evening walk is three-sixths mile. Which walk is
MArishka [77]

Answer:

Evening walk is shorter.  

Step-by-step explanation:

We have been given that a nature center offers 2 guided walks. The morning walk is two-third mile. The evening walk is three-sixths mile. We are asked to find the shorter walk.

Let us compare both fractions by making the same denominator.

\text{Two-thirds}=\frac{2}{3}

\text{Two-thirds}=\frac{2\times2}{3\times2}

\text{Two-thirds}=\frac{4}{6}

\text{Three-sixth}=\frac{3}{6}

Upon making common denominator, we can see that two-thirds are equal to four sixths.

Since three-sixths is less than four-sixths, therefore, evening walk is shorter.

We will draw two rectangles, one with 6 sub-parts and other with three sub-parts.

We will shade 2 parts out of 3 sub-parts to represent 2/3 and shade 3 parts out of 6 sub-parts to represent 3/6.

Then we will further divide three sub-parts into 6 sub-parts as shown in the diagram that will represent 4/6.
