Answer: The correct option is

(C) $\dfrac{1}{16}.$

Step-by-step explanation: Given that when a number x is multiplied by 6, the result is $\dfrac{3}{8}.$

We are to find the value of x.

According to the given information, the equation can be written and solved as follows :

$x\times6=\dfrac{3}{8}\\\\\\\Rightarrow x=\dfrac{1}{6}\times\dfrac{3}{8}\\\\\\\Rightarrow x=\dfrac{1}{16}.$

Thus, the required value of x is $\dfrac{1}{16}.$

Option (C) is CORRECT.

Find the volume of a sphere with a circumference of 48 pi ft. Write your answer in terms of pi .

meriva

Answer:

18,432 pi cubic ft

Step-by-step explanation:

This problem can be solved using formula to find circumference and volume of sphere

for any sphere with radius r

circumference of sphere is 2* pi * r

volume of sphere is found by using formula 4/3*(pi*r^2)

Given circumference of sphere is 48 pi ft

therefore

2* pi * r = 48 pi ft

r = 48 pi ft/ 2* pi = 24 ft

substituting the value of r is formula of volume of sphere we have

volume of sphere is = 4/3*(pi*24^3) = 18,432 pi cubic ft

Let x and y be independent each uniformly distributed on {1,2,...,n} find p(x < y )

bulgar [2K]

If we draw the contingency table of x (vertical) against y (horiz.), we have a square.
For n=4, we have (legend: < : x<y = : x=y > : x>y

y 1 2 3 4
x
1 = < < <
2 > = < <
3 > > = <
4 > > > =

We see that there are n(n-1)/2 cases of x<y out of n^2.
Therefore,
p(x<y)=n(n-1)/(2n^2)=(n-1)/(2n)

However, if the sample space is continuous, it will be simply p(x<y)=1/2.

SOLVE THIS EXTREMELY IMPORTANT EQUATION

finlep [7]

Answer:

Option B; EF = ( About ) 4.47 units, Perimeter of Δ EFG = ( About ) 12.94 units

Step-by-step explanation:

If we were to consider the height of this triangle EFG, it would be 4 units of length, supposedly splitting base GF into two ≅ parts, each 2 units of length. First let us name the point drawn to base GF ⇒ point H, so that the height of Δ EFG ⇒ EH. Now as EH splits GF into two ≅ parts, by Converse to Coincidence Theorem, Δ EFG ⇒ Isosceles Δ;

EH and FH are legs of a right triangle EFH, so that Pythagorean Theorem can be applied to solve for the length of EF and EG, knowing that as Δ EFG ⇒ Isosceles Δ, EF ≅ EG;

( EH )^2 + ( FH )^2 = ( EF )^2,

( 4 )^2 + ( 2 )^2 = ( EF )^2 ⇒ take square of 4 & 2,

16 + 4 = ( EF )^2 ⇒ combine like terms,

( EF )^2 = 20 ⇒ take square root on either side to solve for EF,

EF = √ 20 = ( About ) 4.47 units = EG,

Perimeter of Δ EFG = EF + GF + EG = 4.47 + 4 + 4.47 = ( About ) 12.94 units,

Solution; Option B
