The mean and standard deviation of a normal distribution are 150 and 12 respectively. What percentage of values lie between:
a) 138 and 162
b) 126 and 174
c) 126 and 162
d) 162 and 174
Answers
Answer:
Step-by-step explanation:
Use a calculator with built-in statistical functions. The function applying here is normcdf(, the "cumulative density function."
(a) The percentage of values lying between 138 and 162 is
norm(138,162, 150, 12), which comes out to 0.683, or 68.3%.
(b) Find norm(126, 174, 150,12): 0.945, or 94.5%
(c) Find norm(126,162, 150,12); 0.819, or 81.9%
(d) Find norm(162, 174,150,12): 0.136, or 13.6%

what are the roots of the equation in the simplest a+bi form?
Answers
Answer:
The answer is
[tex]x = - 5 + 8 \: i \: \: \: \: or \: \: \: \: x = - 5 - 8 \: i \\ [/tex]Step-by-step explanation:
x² + 10x + 89 = 0
Using the quadratic formula
[tex]x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]From the question
a = 1 , b = 10 , c = 89
Substitute the values into the above formula and solve
We have
[tex]x = \frac{ - 10\pm \sqrt{ {10}^{2} - 4(1)(89)} }{2(1)} \\ = \frac{ - 10\pm \sqrt{100 - 356} }{2} \\ = \frac{ - 10\pm \sqrt{ - 256} }{2} \\ = \frac{10\pm 16 \: i}{2} [/tex]Separate the real and imaginary part
That's
[tex]x = - \frac{10}{2} \pm \frac{16}{2} \: i \\ x = - 5\pm8 \: i[/tex]We have the final answer as
[tex]x = - 5 + 8 \: i \: \: \: \: or \: \: \: \: x = - 5 - 8 \: i \\ [/tex]Hope this helps you

Points [tex]\frac{3}{2} , \frac{-3}{2} , 1.5 , -1.5 , 1 \frac{1}{2} , -1 \frac{1}{2}[/tex] have same absolute value as 3/2
What is an absolute value?The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign.
For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5.
According to the question
numbers with an absolute value of 3/2 are
[tex]absolute value of |\frac{-3}{2}| = \frac{3}{2} \\absolute value of |1.5| = 1.5 or \frac{3}{2} \\\\absolute value of |-1.5| = 1.5 or \frac{3}{2} \\\\absolute value of |1\frac{1}{2} | = \frac{3}{2} \\\\\\[/tex]
[tex]absolute value of |-1\frac{1}{2} | = \frac{3}{2}[/tex]
Number line is attached below
Hence, Points [tex]\frac{3}{2} , \frac{-3}{2} , 1.5 , -1.5 , 1 \frac{1}{2} , -1 \frac{1}{2}[/tex] have same absolute value as 3/2 .

The weights of 3 puppies at one week old were 6.5 ounces, 7.3 ounces, and 6.4 ounces. If each
puppy gained 2.1 ounces, how much would the puppies weigh?
The first puppy would weigh ounces, the second puppy would weigh ounces, and the third
puppy would weigh ounces.
(Type integers or decimals.)
Answers
The answers are 8.6 ounces, 9.4 ounces, and 8.5 ounces
Explanation:
To find how much each puppy weights simply add the weight they gained (2.1 ounces) to the weight of each puppy at one week old. The process to add the weights is shown below:
First Puppy
6.5 ounces (weight at one week old) + 2.1 ounces (weight gained)
Align both numbers using the period as the reference and add
6.5
+ 2.1
8.6
The weigh of the first puppy is 8.6 ounces which can be rounded as 9 ounces (integer)
Second Puppy
Now, repeat the process
7.3 ounces + 2.1 ounces
7.3
+ 2.1
9.4
The weigh of this puppy is 9.4 ounces or 9 ounces (integer) if rounded
Third Puppy
6.4 ounces + 2.1 ounces
6.4
+ 2.1
8.5
The weight of the third puppy is 8.5 ounces which can be rounded as 8 ounces or 9 ounces (integers) depending on the rounding method.

The function h (x) = StartFraction 1 Over x squared + 1 EndFraction is the result of the composition f(g(x)). If g(x) = x2 + 1, what is f(x)? f (x) = StartFraction 1 Over StartRoot x EndRoot f (x) = StartFraction 1 Over x + 1 EndFraction f (x) = StartFraction 1 Over x squared + 1 EndFraction
Answers
Answer:
f(x) = 1/x
Step-by-step explanation:
Given h(x) = 1/(x²+ 1) and g(x) = x²+ 1. If h(x) = f(g(x)) then;
1/(x²+ 1) = f(x²+ 1)
f(x²+ 1) = 1/(x²+ 1)
This means that function of (x²+ 1) will give 1/(x²+ 1). To get f(x), we will simply replace x²+ 1 in the function f(x²+ 1) with x to give;
f(x) = 1/x
Hence the function of x i.e f(x) is 1/x

HELP! IT'S OVERDUE! An engineer is building a bridge that should be able to hold a maximum weight of 1 ton. He builds a model of the bridge that is exactly 4 times smaller than the actual bridge. 16 ounces = 1 pound. 2,000 pounds = 1 ton.

I need the domain range and function. With an explanation

Problem 1

Domain = All real numbers, interval notation [tex](-\infty, \infty)[/tex]Range = [tex]y \le 4[/tex], interval notation [tex](-\infty, 4][/tex]Is it a function? Yes==================================================
Explanations:
The left most point is when x = -3, and we are not including this value due to the open hole. The other endpoint is included because it is a filled in circle. The domain is therefore [tex]-3 < x \le 3[/tex] which in interval notation is (-3, 3]. We have the curved parenthesis meaning "exclude endpoint" and the square bracket says "include endpoint". The range is a similar story but we're looking at the smallest and largest y values. Though be careful about which endpoint is open/closed. We have a function because it passes the vertical line test.The smallest x value is x = -2. There is no largest x value because the arrows say to go on forever to the right. We can say the domain is [tex]x \ge -2[/tex] which in interval notation is [tex][-2, \infty)[/tex]. The range is [tex](-\infty, \infty)[/tex] to indicate "all real numbers". This graph fails the vertical line test, so it is not a function. The vertical line test is where we check to see if we can pass a vertical line through more than one point on the curve. In this case, such a thing is possible which is why it fails the test.This is the same idea as problem 1, though note the endpoints are flipped in terms of which has an open circle and which doesn't. It is not possible to draw a single vertical line to have it pass through more than one point on the curve, so it passes the vertical line test and we have a function.This is a function because it passes the vertical line test. The domain is the set of all real numbers due to the arrows in both directions. Any x value is a possible input. The range is [tex]y \le 4[/tex] which is the same as saying [tex](-\infty, 4][/tex] in interval notation. This is because y = 4 is the largest y value possible. There is no smallest y value due to the arrows.3,6 reflected across the line y=3

(3,6) reflected across the line y=3
y = 3 is parallel to x- axis, the x-coordinate doesn't change and y-coordinate reflects as y - 2*3
(x, y) → (x',y') = (x, y -2*3)(3, 6) → (3, 6 -6) = (3, 0)Answer is (3,0)

Cynthia wants to buy a rug for a room that is 18ft wide and 26ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 240 square feet of carpeting. What dimensions should the rug have?
Answers
The room is 18 ft by 26 ft which is 468 ft^2
She can afford a 240 ft^2 rug
12 * 20 = 240
She can afford a rug that is 12 ft wide by 20 ft long
The dimensions that the rug she wants to buy should have is: 12 ft by 240 ft
How to find the area of the rectangle?The formula for the area of a rectangle is expressed as:
Area = length * Width
Now, we are told that:
Dimensions of room = 18 ft by 26 ft
If she leaves a strip of 3ft across the room, then, we can say that area that needs carpeting = 12 ft by 20 ft

I don't know what $89.25 represents in the question but I can just assume that he saved that much more. "x" represents how much more he needs.
