Answer:

about 117 times

Step-by-step explanation:

No. of possible outcomes of a cube: 6

2 out the 6 possible outcomes are less than 3,

and therefore, No. of favorable outcome: 2

P(less than 3)= No. of favorable outcome / No. of possible outcomes

=2/6 => 1/3

if you roll a standard number cube 350 times then,

Prediction= number of rolls x (P(less than 3))

=350 x 1/3

≈117 times.

Which expression is equivalent to 6 Superscript 4 times 6 cubed? (6 times 6 times 6 times 6) (6 times 6 times 6) (6 6 6 6) times

malfutka [58]

The expression which is equivalent to 6 Superscript 4 times 6 cubed and posses same value as this expression is,

$6\times6\times6\times6)\times6$

<h3>What is the equivalent expression?</h3>

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The given statement for the expression is 6 Superscript 4 times 6 cubed. This expression cab be written as,

$6^4\times6$

Suppose the equivalent expression of this equation is n. Thus,

$n=6^4\times6$

The 4 power of number 6 means that the number 6 should be multiplied 4 times.

$n=(6\times6\times6\times6)\times6$

Hence, the expression which is equivalent to 6 Superscript 4 times 6 cubed and posses same value as this expression is,

$6\times6\times6\times6)\times6$

Kim, Laura and Molly share £385

trapecia [35]

Set x equal to the amount of money Kim gets, and y for Molly's money.

x = 2/5y, since the ratio is 2:5.
y = 105 + x, since Molly has 105 more pounds than Kim.

Substitute x into this equation, so that y = 105 + 2/5y. Subtract 2/5y from both sides to get 3/5y = 105. Divide each side by 0.6 (equivalent to 3/5) and you get y = 175, which is how much Molly has. Kim gets 2/5 of Molly's share (or 105 fewer pounds), so she has 70.

70 + 175 (Kim and Molly's shares) is equal to 245. Therefore, Laura receives the remaining 140 pounds.

140/385 = a/100
Cross multiply so that 385a is 14000. Divide by 385 to get 36.4 (rounded).

Thus, Laura receives about 36.4% of the total money. Hope this helps (:
