In a game the player wins if he rolls a 6 on a number cube. If the number cube is rolled 18 times, then what is a reasonable pre

SVETLANKA909090 [29]

If the number cube is rolled 18 times, then the number of unsuccessful rolls = 90 unsuccessful rolls.

Step-by-step explanation:

step 1: A cube has six faces and each face is numbered from 1 to 6.

step 2: The win in the game requires the number 6, when a cube is rolled.

step 3: On rolling a cube, the outcomes are (1,2,3,4,5, and 6).

step 4: Out of these outcomes, 5 are unsuccessful rolls (1,2,3,4,5) and 1 is a successful roll (6).

step 5: If the cube is rolled 18 times,

then the number of unsuccessful rolls = 18 * 5 unsuccessful rolls

= 90 unsuccessful rolls.

Please Help!!

Answer:

0.0069

Step-by-step explanation:

This is a power series problem.

The taylor power series expansion for sin(x) = x - x³/3! + (x^(5))/5! - (x^(7))/7! + (x^(9))/9! .......

Our question says we should use the first 5 terms to find the value of sin(π). Thus;

sin(π) = π - π³/3! + (π^(5))/5! - (π^(7))/7! + (π^(9))/9!

This gives;

π - (π^(3)/6) + (π^(5))/120 - (π^(7))/5040 + (π^(9))/362880 ≈ 0.0069

Tanner made his aunt a garden. The width is 9 4/5 ft and the length is 5 3/4 ft. What is the area of

ratelena [41]

Answer:

56.35 ft^2, or 56 7/20 ft^2

Step-by-step explanation:

One way of doing this problem quickly is to convert both measurements into improper fractions before multiplying them:

9 4/5 = 49/5 and 5 3/4 = 23/4.

Then the area of the garden is 49/5 times 23/4, or 1127/20 ft^2, or

56.35 ft^2, or 56 7/20 ft^2.

How do i do this ???

Westkost [7]

a peculiar thing about the centroid of a triangle, is that it cuts all the medians in a 2:1 ratio, so JP : PM are on a 2:1 ratio, thus

$\bf JP:PM\qquad 2:1\qquad \cfrac{JP}{PM}=\cfrac{2}{1}\implies \cfrac{27}{PM}=\cfrac{2}{1}\implies \cfrac{27}{2}=PM\\\\-------------------------------\\\\JM=JP+PM\implies JM=27+\cfrac{27}{2}\implies JM=\cfrac{54+27}{2}\\\\\\JM=\cfrac{81}{2}\implies JM=40\frac{1}{2}$
