In a two-tailed hypothesis test the test statistic is determined to be Z = -2.5. The p-value for this test is:_______
a. 0.0062
b. -1.25
c. 0.4938
d. 0.025
e. 0.0124
Answers
Answer:
e. 0.0124
Step-by-step explanation:
Given that:
In a two-tailed hypothesis test, the test statistic is determined to be Z = -2.5
The p-value for this test can be determined from the Z tables at Z = -2.5
Using the EXCEL FUNCTION ( = NORMDIST (-2.5) )
Since the hypothesis is two-tailed, then;
The p-value = 2 × (= NORMDIST (-2.5))
The p-value = 2 × 0.00620
The p-value = 0.0124
The EXCEL FUNCTION computation can be seen in the attached file below.
Complete this expression using the distributive property: 5(4 + 8) =
Answers
Explanation: The distributive property tells us when there's a number outside a set of parenthses, you can multiply it times each of the terms that are inside the set of parenthses and then add those products together.
So in this problem, we can multiply 5(4) + 5(8)
which simplifies to 20 + 40 which equals 60.
Answer:
5(4) + 5(8)

I cut a long piece of wood into 50cm pieces. I manage to cut
w pieces of wood, and there is 20cm left over.
How long was the wood to start with?
Answers
Answer:
[tex]WoodLength = 50w + 20[/tex]
Step-by-step explanation:
Given
Length of Pieces = 50cm
Number of Pieces = w
Left over = 20cm
Required
Determine the length of the wood
Start by multiplying the number of pieces by the length of each pieces
[tex]Result = Length * Number[/tex]
[tex]Result = 50 * w[/tex]
[tex]Result = 50 w[/tex]
Lastly, add the leftover to get the actual length of the wood
[tex]Wood Length = Result + Leftover[/tex]
Substitute 50w for Result and 20 for Leftover
[tex]WoodLength = 50w + 20[/tex]
Hence, the length of the wood is 50w + 20
Two cruise ships left the same port. After two hours, Ship A is 30 miles west and 18 miles north of the port and Ship B is 10 miles west and 27 miles south of the port. If there is a tug boat located one-fifth of the way from Ship A to Ship B, find the location of the tug boat relative to the port.
Answers
Answer:
30.83 miles
Step-by-step explanation:
Distance of ship A from port is x
X²= 18²+30²
X²= 324+900
X²=1224
X=34.9857 miles
Bearing from port
Tan tita= 18/30
Tita = tan^-1 3/5
Tita= 31°
N 31° E
Distance of ship B from port is y
Y²= 27²+10²
Y²= 729+100
Y²= 829
Y=28.7924 miles
Bearing from port
Tan tita= 2.2
Tita= 69.7°
90-69.7= 20.3
N 20.3°W
Distance between the two ships is z
Z²=34.9857²+28.7924²-2(24.9857)(28.7924)cos(31+69.7°)
Z²= 2053+267.1
Z²= 2320.1
Z=48.18 miles
One fifth of 48.18
=9.63 miles
Distance of the boat is D
D/sin 60 = 34.9857/sin 100.7
D=30.83 miles

2. Eleanor Raymond works full time while her husband, Peter, attends college and works part
time. Their income for the last two weeks consisted of an August 17 paycheck of Eleanor's for
$380.48, $16.50 for a birthday present Peter returned on August 19, Peter's paycheck on
August 21 for $120.00, Peter's sale of some of his college textbooks on August 23 for $13.65,
and a check from Peter's father for $100.00 that arrived August 25. Record and total Eleanor
and Peter's income for this two-week period.
Answers
Answer:
Eleanor and Peter's total income
= $597.63
Step-by-step explanation:
Eleanor's Income:
Paycheck = $380.48
Eleanor's Expenses:
Birthday gift= $16.50
Peter's income
Paycheck = $120
Sales of his college textbook = $13.65
Check from Peter's father= $100
Peter's total income =Paycheck + Sales of his college textbook + Check from Peter's father
= $120 + $13.65 + $100
= $233.65
Eleanor and Peter's total income
= Eleanor's Income + Peter's total income - Eleanor's Expenses
= $233.65 + $380.48 - $16.50
= $597.63
Eleanor and Peter's total income
= $597.63

Given an odd function, which of the following transformations would result in an odd function? Check all that apply.
horizontal translation
reflection across the x-axis
vertical stretch
vertical translation
Answers
Answer:
Vertical stretch and reflection across the x axis
Step-by-step explanation:
Vertical stretch and reflection across the x-axis are the odd functions.
What is a vertical stretch?Vertical stretch occurs when a base graph is multiplied by a certain factor that is greater than 1. This results in the graph being pulled outward but retaining the input values (or x). When a function is vertically stretched, we expect its graph's y values to be farther from the x-axis.
What is a vertical reflection over the x-axis?Another transformation that can be applied to a function is a reflection over the x– or y-axis. A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis.

Greetings from Brasil...
We have here a composite function.... Where there is X in function F(X), we will replace by G(X)
F(X) = 2X + 4
G(X) = X - 7
H(X) = 9 - X
F(X) = 2X + 4
F(G(X)) = 2·(GX) + 4
F(G(X)) = 2·(X - 7) + 4
F(G(X)) = 2X - 14 + 4

Answers
This question is incomplete
Complete Question
The body of 154-pound person contains approximately 2 x 10^-1 milligrams of gold and 6 x 10^1 milligrams of aluminum.
Based on this information, the number of milligrams of aluminum in the body is how many times the number of milligrams of gold in the body?
Answer:
300 times
Step-by-step explanation:
From the above question, we are told:
The body of 154-pound person contains approximately 2 x 10^-1 milligrams of gold and 6 x 10^1 milligrams of aluminum.
We create a proportion
2 × 10^-1 mg of gold : 6 × 10^1 mg of aluminum
= 0.2 mg of gold : 60 mg of aluminum
Therefore, the number of milligrams of aluminum in the body is how many times the number of milligrams of gold in the body is calculated as:
60mg ÷ 0.2 mg
= 300
Therefore, the number of milligrams of aluminum in the body is 300 times the number of milligrams of gold in the body

A football field is 120 yards by 53.333 yards. What is the area of the football field in acres if 1 acre=43560 ft?? Use correct
significant figures when answering this question.
Answers
Answer:
The area of the pitch in an acre is 1.32 acreStep-by-step explanation:
This problem requires to test our understanding of unit conversion, and we are expected to present our answer in an acre
first, let us convert from the yard to feet
given that the dimension of the pitch is
120 yards by
53.333 yard
1 yard is 3 foot
120 yards will give x
cross multiply we have
x1= 120*3
x1= 360 feet
also the second dimension is
x2= 53.333*3
x2= 159.999
x2= 159.999 feet
the area of the pitch is
area= 159.999*360
area= 57599.64 ft^2
Note: an acre is a unit for land area (1 acre=43560 ft^2)
if 1 acre = 43560 ft^2
x acre = 57599.64 ft^2
cross multiply we have
x acre = 57599.64/43560
x acre = 1.32 acre
