First, let's determine how many standard deviations from the mean the value
(163+1) = 164 is:
 (164 - 125)/15 = 39/15 = 2.6 
 Now using a standard normal table, look up 2.6 to determine the percentage of points that would be that far from the mean. I find a value of 0.49534. Note that is is a half value. So the percentage that will be higher than that will be 0.5 - 0.49534= 0.00466 
 Now multiply by the number of points overall, getting
 0.00466 * 1000000 = 4660 
 So there will be approximately 5000 pixels brighter than 163 gray levels.

In parallelogram DEFG, DH = x + 1, HF = 3y, G H = 3 x − 4 , and HE = 5y + 1. Find the values of x and y. The diagram is not draw
Nana76 [90]

Answer:

see explanation

Step-by-step explanation:

Using the property of parallelograms

• The diagonals bisect each other, hence

DH = HF and GH = HE

x + 1 = 3y and 3x - 4 = 5y + 1 ⇒ 3x = 5y + 5

Solving the 2 equations simultaneously

x + 1 = 3y → (1)

3x = 5y + 5 → (2)

rearrange (1) expressing x in terms of y

x = 3y - 1 → (3)

substitute x = 3y - 1 in (2)

3(3y - 1) = 5y + 5

9y - 3 = 5y + 5 ( subtract 5y from both sides )

4y - 3 = 5 ( add 3 to both sides )

4y = 8 ( divide both sides by 4 )

y = 2

substitute y = 2 into (3)

x = (3 × 2) - 1 = 6 - 1 = 5

Hence x = 5, y = 2

What is the result of subtracting the second equation from the first? \begin{aligned} -7x-y &= 0 \\\\ 7x+8y &= -6 \end{a
Kitty [74]

Answer:

-14x-9y=6

Step-by-step explanation:

We are given with two equations

first equation is  -7x-y=0

second equation is

7x+8y=-6

we find the result of subtracting two equation

subtract the second equation from the first, so

first equation - second equation, multiply second equation by -1  and then add it with first equation

-7x-y=0

-7x-8y=+6

Now add both equations, we get

-14x-9y=6

A=-5
a12 = 1.7

a12 = a+(n-1)d
1.7 = -5+(12-1)d

1.7+5 = 11d

6.7/11 = d
0.60 = d

Iteru [2.4K]

Answer:

a = 4/3k + 4/3q

Step-by-step explanation:

3/4a - q = k

+q          +q

3/4a = k + q

*4/3      *4/3

a = 4/3k + 4/3q
