Basic Computation: Finding Probabilities, let z be a random variable with a standard normal distribution. Find the indicated probability, and shade the corresponding area under the standard normal curve.
P(-1.20 = z = 2.64)
Answers
Answer:
0.8808
Step-by-step explanation:
The objective is to calculate the probability of:
P(-1.20 ≤ z ≤ 2.64)
i.e. the probability that is the area between two z-values.
Thus;
P(-1.20 ≤ z ≤ 2.64) = P(z ≤ 2.64) - P( z ≤ 1.20)
From z table;
P(-1.20 ≤ z ≤ 2.64) = 0.9959 - 0.1151
P(-1.20 ≤ z ≤ 2.64) = 0.8808
We can see the shaded area under the standard normal curve from the image attached below.

For a certain experiment, the available experimental units are 12 people—six females (f) and six males (m). Use (1f, 2f, 3f, 4f, 5f, 6f) to denote the females and (1m, 2m, 3m, 4m, 5m, 6m) to denote the males. There are to be six treatment groups: A, B, C, D, E, and G.

Answers
Answer:
I believe the correct answer would be the last one.
Step-by-step explanation:
The units are supposed to be blocked by gender. However, the first two units in the final option are blocked with two females in one group, and two males in the next. This is inconsistent with the blocking method used for the rest of the units.
The randomized block design is adopted to minimize the risk of systematic error in an experiment. The incorrect assignment of treatment is ;
(1f, 2f), B: (1m, 2m), C: (3f, 3m), D: (4f, 4m), E: (5f, 5m), G: (6f, 6m)Since the units are blocked by gender, then each of the treatment groups should include atleast one of each gender.
For all the assignments given, only the last assignment include groups which contain only one of the gender ; (1f, 2f), B: (1m, 2m),

Find three consecutive integers whose sum is 57????
Answers
Answer:18 19 20
Step-by-step explanation:"Consecutive" means that the integers will follow each other in value, for example: 1, 2, 3 or 4, 5, 6. Also, no decimals are needed here because "integers" are whole, counting numbers. Here is the set up: Let x= the first integer Then X+1= 2nd consecutive integer and x+2= 3rd .
Suppose that x=1 x+1= 1+1=2 and x+2=1+2=3 However, you need specific consecutive numbers whose sum is 57. Remember that sum means to add:
x+ (x+1) + (x+2) = 57 Addition of all 3 consecutive numbers Now solve for x
and substitute into each part to come up with the three integers:
3x + 3= 57 3x=54 x=54/3 = 18 x=18, x+1= 18+1=19 x+2=18+2=20

Julie's parents' 25th anniversary is in 2 years. She'd like to give her parents a vacation package for their anniversary. She anticipates the vacation package will cost her $2000. An account at her bank pays 5% per year compounded monthly. How much does she need to deposit today in this account, so that she can buy the package deal for her parents' anniversary?
a) Simple Interest
b) Future Value with compound interest
c) Future Value with simple interest
d) Effective Rate
e) Present Value with compound interest
Answers
Answer:
e) Present Value with compound interest
Step-by-step explanation:
in order to determine how much money does Julie need to deposit we have to use the present value formula with compound interest:
present value = future value / (1 + i/12)ⁿ
future value = $2,000i/12 = 5%/12 = 0.4167%n = 24$2,000 = present value x (1 + 0.4167%)²⁴
present value = $2,000 / (1 + 0.4167%)ⁿ = $1,810.05
you can also calculate it using the future value formula, but you will end with the present value formula:
future value = present value x (1 + i/12)ⁿ
present value = future value / (1 + i/12)ⁿ ⇒ you are adding 1 more step
you could also calculate it using the present value formula and the effective annual rate:
effective rate = (1 + 0.05/12)¹² - 1 = 5.1162%
present value = $2,000 / (1 + 5.1162)² = $1,810.05 ⇒ but again you are just adding more steps into the process

The weights, in pounds, of the cats in an animal adoption center are normally distributed. If a random sample of cats is taken and the confidence interval is (7.9,12.7), what is the margin of error?
Give a numerical response for your answer. For example, if you found that the margin of error was 2, you would enter 2.
Answers
Answer:
2.4
Step-by-step explanation:
Given that :
The confidence interval = ( 7.9 , 12.7 )
The Margin of error M.O.E = Interval width/2
where;
The interval width = UCL - LCL
The interval width = 12.7 - 7.9
The interval width = 4.8
∴
The Margin of error M.O.E = 4.8/2
The Margin of error M.O.E = 2.4

The length of the longer leg of a right triangle is 16 cm more than four times the length of the shorter leg. The length of the hypotenuse is
17 cm more than four times the length of the shorter leg. Find the side lengths of the triangle.
Answers
The side lengths of the triangle are 12 cm, 64 cm, and 65 cm.
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let's denote the length of the shorter leg as "x". Then, according to the problem statement, the length of the longer leg is "16 cm more than four times the length of the shorter leg", which can be expressed as 4x + 16.
Also, the length of the hypotenuse is "17 cm more than four times the length of the shorter leg", which can be expressed as 4x + 17.
Using the Pythagorean theorem, we know that in a right triangle, the sum of the squares of the two shorter sides equals the square of the hypotenuse.
So, we can write an equation as follows:
x² + (4x + 16)² = (4x + 17)²
Simplifying this equation, we get:
x² + 16x² + 128x + 256 = 16x² + 136x + 289
Bringing all the terms to one side, we get:
x² - 8x - 33 = 0
We can solve this quadratic equation using the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / 2a
Where a = 1, b = -8, and c = -33.
Plugging in these values, we get:
x = (8 ± √(8^2 - 4(1)(-33))) / 2(1)
x = (8 ± √(256)) / 2
x = 4 ± 8
Therefore, we have two possible values for x: x = -4 or x = 12. Since the length of a side of a triangle cannot be negative, we reject x = -4 and conclude that x = 12.
Substituting this value of x into the expressions we derived earlier, we get:
Length of shorter leg: x = 12 cm
Length of longer leg: 4x + 16 = 4(12) + 16 = 64 cm
Length of hypotenuse: 4x + 17 = 4(12) + 17 = 65 cm
Hence , the triangle is solved
