what is the p value definition
Answer:
statistics, the p-value is the probability of obtaining results as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is correct. ... A smaller p-value means that there is stronger evidence in favor of the alternative hypothesis.
When 1580 is divided into 13 equal parts, the remainder is 7. What is a correct way to write the quotient? 121.7 121 + 7 1217 over 1580 1217 over 13
Answer:
121.54
Step-by-step explanation:
1580÷13=121 r 7
7 over 13 is 0.538462
rounded off to 2 decimal places:0.54
so 121+0.54
121.54

I need the work will it to how to do it step by step Ik it sounds dumb but I need help.
Answer:
5/18
Step-by-step explanation:
first you want to flip 2/5 to 5/2 and change the division sign to multiplication so it would look like 1/9 x 5/2
then multiply 1 and 5 then 9 and 2 so the top and bottom to get 5/18
side note: but if it were 1/9 x 3/7 you would change the 3 to a 1 and the 9 to a 3 because they multiply so ask yourself how many times does three go into 9 so it would be 1/3 x 1/7= 1/21
hope this helped :) also what math are you taking bc if it is under algebra 1 or something i can help with any questions you have just message me and ill be happy to help :)
how would i simplify (4v^3 w) (-2w^3)
Answer:
You would distribute the imaginary 1 to 4w cubed and then do the same to the other side as well so 1 times-2w cubed would still be -2w and then 4w cubed would still be 4v and the answer is: -8v^3w^4

Maggie's brother is 3 years younger than four times her age. The sum of their ages is 62. How old is Maggie? Maggie is years old.
Answer:
Maggie is 13 years old.
Step-by-step explanation:
1M + 1B = 62
rearrange to get:
1B = 62 - 1M
4M - 3 = 1B
substitute B with 62 - 1M so there is only one variable. this gives:
4M - 3 = 62 - 1M
Get all the variables on one side:
4M + 1M - 3 = 62
Get all non variables on the other side:
4M + 1M = 62 + 3
simplify:
5M = 65
Divide both sides by 5 to get the M by itself:
M = 13.
BONUS:
M + B = 62
B = 49
So her brother is 49 years old.
Maggie is 13 years old.
the coordinates of point T are (0,4). The midpoint of ST is (6,-7). Find the coordinate of point S
Answer:
Step-by-step explanation:
(x + 0)/2 = 6
x + 0 = 12
x = 12
(y + 4)/2 = -7
y + 4 = -14
y = -18
(12, -18)
The coordinate of the point S will be (12,-18).
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line.
Given that the coordinates of point T are (0,4). The midpoint of ST is (6,-7). The coordinates of the point S will be calculated as below:-
The x-coordinate is calculated as below:-
(x + 0)/2 = 6
x + 0 = 12
x = 12
The y-coordinate is calculated as below:-
(y + 4)/2 = -7
y + 4 = -14
y = -18
Therefore, the coordinate of the point S will be (12,-18).

Newman is building a patio. He estimates that he can install 8 square feet of paver bricks every quarter-hour. How many square feet does Newman install per hour?
Answer:
32 square feet
Step-by-step explanation:
From the above question, we know that: for Newman:
8 ft² = 1/4hour
x ft² = 1 hour
We Cross Multiply
8ft² × 1 hour= x ft² × 1/4hour
xft² = 8ft² × 1 hour/1/4 hours
x ft² = 32 ft²
Therefore, Newman installs 32 square feet per hour

2.23 reapting (2 and 3) decimal as a fraction
Answer:
221/99
Step-by-step explanation:
2.23 repeating equals x
223.23 repeating equal 100x
subtract x from 100x and you get 99x=221
divide by 99 on both sides of the equal sign and you get x=221/99

One cell phone company offers a plan that costs $28.99 and includes unlimited night and weekend minutes. Another company offers a plan that costs $16.99 and charges $0.35 per minute during nights and weekends. For what numbers of night and weekend minutes does the second company's plan cost more than the first company's plan?
plan1 = 29.99
plan2 =19.99 + .35m
plan2 > plan1
19.99 + .35m > 29.99
.35m > 29.99-19.99
.35m > 10
m > 10/.35
m > 28.6 minutes
it will cost more if you exceed 28 minutes
Answer: the correct answer would be 35 minutes

Suppose point D is in the interior of ∠ABC
, m∠ABC=12x−110
, m∠ABD=3x+40
, and m∠DBC=2x−10
. W
Answer:
[tex]ABC = 130[/tex]
Step-by-step explanation:
Given
[tex]ABC=12x - 110[/tex]
[tex]ABD=3x+40[/tex]
[tex]DBC=2x - 10[/tex]
Required
Determine the measure of ABC --- Missing part of the question
First, we need to determine the value of x
Since, D is an interior of ABC, then
[tex]ABC = ABD + DBC[/tex]
[tex]12x - 110 = 3x + 40 + 2x - 10[/tex]
Collect Like Terms
[tex]12x - 3x - 2x = 110 + 40 - 10[/tex]
[tex]7x = 140[/tex]
Solve for x
[tex]x = 140/7[/tex]
[tex]x = 20[/tex]
Substitute 20 for x in [tex]ABC=12x - 110[/tex]
[tex]ABC = 12 * 20 - 110[/tex]
[tex]ABC = 240 - 110[/tex]
[tex]ABC = 130[/tex]
Leslie cobar's piggy bank 36 coins. Some are quarters and rest are half - dollars. If the total vaule of the coins is $14.75, how many of each of denomination does Leslie have?
Answer:
Leslie has 13 quarters and 23 half-dollars.
Step-by-step explanation:
You can write the following equations from the information given and considering that a quarter is $0.25 and half-dollar is $0.50:
x+y=36 (1)
0.25x+0.50y=14.75 (2), where:
x=amount of quarters
y=amount of half-dollars
First, you can isolate x in (1):
x=36-y (3)
Then, you can replace (3) in (2):
0.25(36-y)+0.50y=14.75
9-0.25y+0.50y=14.75
0.25y=5.75
y=5.75/0.25
y=23
Finally, you can replace the value of y in (3) to find the value of x:
x=36-23
x=13
According to this, the answer is that Leslie has 13 quarters and 23 half-dollars.

If cyanide in a stream next to a gold mine increases from 240 ppm to 360 ppm, what percent increase is this?
Given :
Initial concentration , 240 ppm .
Final concentration , 360 ppm .
To Find :
Percent increase.
Solution :
Percentage increase is given by :
[tex]=\dfrac{Final-Initial}{Initial}\times 100\\\\=\dfrac{360-240}{240}\times 100\\\\=50\%[/tex]
Therefore , percent increase is 50 % .
Hence , this is the required solution .
is 6.2 rational or irrational
Answer:
irrational
Step-by-step explanation:
Answer:
Rational.
Step-by-step explanation:
If a number is rational it can be expressed in a fraction [tex]\frac{x}{y}[/tex] where x and y are integers.
[tex]6.2=\frac{62}{10} = \frac{31}{5}[/tex]
Since 6.2 can be expressed in a fraction, it is rational.
consider the equation 3a+0.1n=123 if we solve this equation for n which equation would result.
Answer:
[tex]n = 1230 - 30a[/tex]
Step-by-step explanation:
Given
[tex]3a + 0.1n = 123[/tex]
Required
Solve for n
[tex]3a + 0.1n = 123[/tex]
Subtract 3a from both sides
[tex]3a - 3a + 0.1n = 123 - 3a[/tex]
[tex]0.1n = 123 - 3a[/tex]
Divide through by 0.1
[tex]n = \frac{123 - 3a}{0.1}[/tex]
Split the fraction
[tex]n = \frac{123}{0.1} - \frac{3a}{0.1}[/tex]
[tex]n = 1230 - 30a[/tex]
5. Why do valid straightedge and compass moves guarantee everyone will produce the same construction?
Answer:
The reason a valid straightedge and compass moves guarantees everyone will produce the same construction is that constructions involving the use of straightedge and compass comprises of a total of five fundamental constructions that are formed with the already constructed points, circles or lines such as the following;
1) Construction of a line that passes through given points
2) Construction of a through a given point and center
3) Creating the point of intersection of two given nonparallel lines
4) Constructing the points of intersection between a line and a circle
5) Constructing the points of intersection of two circles
Due to the limited number of types of construction, following clearly defined steps of construction, ensures that the same construction is produced by everyone
Step-by-step explanation:
