Answer:
Z scores for:
a) 76 = 1.33333
b) 38 = -1.83333
c) 50 = -0.83333
Step-by-step explanation:
Z score formula is:
z = (x-μ)/σ where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Mean = 60
Standard deviation = 12.
a) 76
z = (x-μ)/σ
z = 76 - 60/12
z score = 1.33333
b) 38
z = (x-μ)/σ
z = 38 - 60/12
z score = -1.83333
c) 50
z = (x-μ)/σ
z = 50 - 60/12
z score = -0.83333
simplify 3x[18+{3+4÷(4-2)}]

A square field has 3,844 sq. meters of land. What is the width of the field?
Answer:
The side length is 62 meters
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
3844 m^2 = s^2
Take the square root of each side
sqrt( 3844 m^2) = sqrt(s^2)
62 m= s
The side length is 62 meters

What does “each point of a line maps to itself” mean? I don’t understand it what it means for it to map to itself.
Answer:
Step-by-step explanation:
For example if you have a function f(x) = x - 1, then x = 1 is a zero of this function because using it as x gives 1 - 1 = 0. The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.

Write the equation of the line in slope-intercept form.
Answer:
y = -½x + 3
Step-by-step explanation:
The equation of a line in slope-intercept form is
y = mx + c
where m is the gradient (slope) and c is the y-intercept
We can find the gradient and intercept from the two points on the diagram
The points are:
(0, 3) and (4, 1)
The y-intercept is when x = 0
we are already given this point so
c = 3
now we can use our other point to find m. So:
1 = 4m + 3
-2 = 4m
-½ = m
Now we can put both variables into our slope-intercept form
y = -½x + 3

A bag contains 3 red marbles, 8 blue marbles and 7 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be green?
Answer:
A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.
Total = 18 marbles.
Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.
Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.

The formula P= 2/+ 2w means that the perimeter of a rectangle is equal to
twice the sum of its length and its width.
Solve P = 21+ 2 w for /
Answer:
D. [tex] l = \frac{P - 2w}{2} [/tex]
Step-by-step explanation:
Given:
[tex] P = 2l + 2w [/tex]
Required:
Solve for l
Solution:
To solve for l, we would make l the subject of the given formula.
[tex] P = 2l + 2w [/tex]
[tex] P = 2(l + w) [/tex]
Divide both sides by 2
[tex] \frac{P}{2} = \frac{2(l + w)}{2} [/tex]
[tex] \frac{P}{2} = l + w [/tex]
Subtract w from both sides
[tex] \frac{P}{2} - w = l + w - w [/tex]
[tex] \frac{P}{2} - w = l [/tex]
[tex] \frac{P}{2} - \frac{w}{1} = l [/tex]
[tex] \frac{P - 2w}{2} = l [/tex]
Rewrite
[tex] l = \frac{P - 2w}{2} [/tex]

Solve this equation
100x + 300 = 200
Answer:
-1
Step-by-step explanation:
100x=200-300
100x=-100
100x/100=-100/100
x=-1
After solving this equation we get, 100x + 300 = 200 x = -1.
To solve this equation
100x + 300 = 200,
Subtract 300 on both side,
100x + 300 - 300 = 200 - 300
100x = -100
Divide 100 on both side,
x = -1
Therefore, After solving this equation 100x + 300 = 200 we get x = -1.
