Step-by-step explanation:

We can break this up into pieces, first we do, 7/8 - 1/4, find the least common denominator which is 8, so the equation will be 7/8 - 2/8, which we can now subtract and will give us, 5/8, now that we have done that, we can do 5/8 - 1/2. Since we know that half of 8 (our denominator) is 4. Then the equation would be 5/8 - 4/8, which brings us to 1/8 as our final answer.

Cheers!

Answer: You have to get rid of the variables (the x's) so subtract 2x from 2x and 11x then go from there.

Answer:

See below

Step-by-step explanation:

Given there are 56 M&M's:

Expected Value of Blue = 56(0.24) = 13.44
Expected Value of Brown = 56(0.14) = 7.84
Expected Value of Green = 56(0.16) = 8.96
Expected Value of Orange = 56(0.20) = 11.20
Expected Value of Red = 56(0.13) = 7.28
Expected Value of Yellow = 56(0.14) = 7.84

Remember to use $np$ to calculate expected value! This will especially be helpful if you are conducting a chi-squared test of independence.

You saved $1,240 and your sister agrees to put it in a savings account at her credit union so you can earn interest. You earned

leva [86]

The amount after 2 years is $2,295.

Given that,

The invested amount is $1,240.
The rate of interest is 8%.
The number of years is 2 × 4 = 8

Based on the above information, the amount after 2 years is

Future value = Present value ×(1 + rate of interest)^number of years

= $1,240 × (1 + 0.08)^8

= $1,240 × 1.08^8

= $2,295

Therefore we can conclude that the amount after 2 years is $2,295.

Solve the system of equations using the substitution method.

ANTONII [103]

The solution of system of equations is: x = 1.6 and y = 1.2

Step-by-step explanation:

Given equations are:

$y = 2-\frac{1}{2}x\ \ \ \ Eqn\ 1\\x-3y = -2\ \ \ eqn\ 2$

Putting $y = 2-\frac{1}{2}x$ in equation 2

$x - 3(2-\frac{1}{2}x) = -2\\x - 6 + \frac{3}{2}x = -2\\x +\frac{3}{2}x = -2+6\\\frac{2x+3x}{2} = 4\\\frac{5x}{2} = 4\\5x = 4 * 2\\5x = 8\\x = \frac{8}{5}\\x = 1.6$

Putting x = 1.6 in equation 2

$1.6-3y = -2\\-3y = -2-1.6\\-3y =- 3.6$

Dividing both sides by -3

$\frac{-3y}{-3} = \frac{-3.6}{-3}\\y = 1.2$

Hence,

The solution of system of equations is: x = 1.6 and y = 1.2
