Mathematics

3 0
First find the slope by calculating rise (change in x) over run (change in y).

(4/5)-0/0-(-5)

(4/5)/5=0.16

The y intercept is 4/5. We know this because y interceot is the value of y when x is 0.

Then plug this into y=mx+b where m is slope andb is y intercept.

Final answer: y=0.16x+0.8 or y= 4/25x+ 4/5

ABDC is a trapezoid. Line AB = 2.5, and Line EF = 4.5. What is the length of Line CD ?
Darina [25.2K]
The line CD is the median of thre trapezoid, therefore its measures is shown below:
 You must sum the largest base and the shortest base and divide both of them by 2, as following:
 CD=(4.5+2.5)/2
 CD=7/2
 CD=3.5
 Therefore, as you can see, the measure of the line CD is 3.5
 The answer is: 3.5

How do I find the n in A=P(1+(r/n)^(nt)?
dmitriy555 [2]
This is the formula for compounded interest.
P is the principal investment,
r is the rate (6%=0.06)
n is the number of times compounded per year (n=12 is monthly, n=2 is twice per year)
T is the number of years past
And A is the amount of money after t years with a rate r compounded n times per year staring at P amount
Final answer:
n is the number of times per year the interest is compounded.
Hope I helped, and sorry it took this long for you to get an answer.

There is one error in one of five blocks of a program. To find the error, we test three randomly selected blocks. Let X be the n
marusya05 [52]
Probability(error in one block)= 1/5
<span>Probability(error in 3 blocks)= 3*(1/5)= 0.6</span>

Let, 
     0 = No error
<span>     1 = error
</span>Hence.
E(x) = 0.4 x 0 x+0.6 + 1 
        = 1.6

Tristen is packing lunch boxes for the school trip. Each lunch box consists of 1 sandwich, 1 fruit, and 1 drink. Tristen can cho
Lerok [7]

Step-by-step explanation:

3*4*2=24

Even if he doesn't use them all, he has 24 choices.

These kind of problems are permutation type problem. Order is not critical. Imagine yourself preparing such a meal. You have choices to be made in Sandwiches, fruits and drinks. It does not matter which order you set up the lunch box. It only matters that you chose.

You can't leave one out, nor does the problem allow you to trade (say) 2 drinks for one fruit.
