a fair number cube labeld 1,2,3,4,5,6 is rolled a hundred times. about how many times could you expect to roll a three?

Vsevolod [243]

So probability is (desired outcomes)/(total possitlble outcomes)
desired is 1 since 3 appaears once on the cube
6 total possible

so probaity of rolling a3 is 1/6

100 times
100 times 1/6=100/6=16 and 2/3 times
round up
17 times

Slope-10 pass through (2,-5)

ahrayia [7]

Slope = -10
pass through (2,-5)
y = mx + b
so
b = y - mx
b = -6 - (-10) (2)
b = -6 + 20
b = 14

equation
y = -10x + 14

I have k quarters, five less quarters than nickels and one more than twice as many dimes as quarters. Find the value of the coin

Alenkinab [10]

Answer:

(35k + 20) cents

Step-by-step explanation:

First of all, let us have the value of each unit:

1 quarter = 25 cents

1 nickel = 5 cents

1 dime = 10 cents

Given that number of quarter = k

Quarters are 5 lesser than Nickels, so number of nickels = k+5

One more than twice as many dimes as quarters:

k = 2 $\times$ Number of Dimes + 1

So, number of dimes = $\frac{1}{2}(k-1)$

Value of quarters = $25 \times k$ cents

Value of nickels = $5 \times (k+5) = (5k+25)\ cents$

Value of dimes = $\frac{1}{2}(k-1) \times 10 = (5k-5)\ cents$

So, total value of coins =

$25k + 5k +25 +5k-5\\\Rightarrow (35k+20)\ cents$
