A golfer played in a tournament. His scores are shown in the table.
Use the data set to select all true statements.
A. The sum of scores of all 4 days is +1.
B. The difference between scores from day 2 and day 4 is +4.
C. The difference between scores for day 1 and day 2 has an absolute value of 4.
D. The scores on day 1 and day 4 are additive inverses.
Answer:
A, C, and D
Step-by-step explanation:
A. Adding up all the numbers gives you a sum of +1 so this is correct.
B. Day 2 has a score of +3 and Day 4 has a score of +1. The difference between those two is +2, not +4 so this is incorrect.
C. Day 1 has a score of -1 and Day 2 has a score of +3. The difference between those two is +4. The absolute value of +4 is +4 so this is correct.
D. Day 1 has a score of -1 and Day 4 has a score of +1. An additive inverse is a value with an opposite sign. One is positive and the other is negative so this is correct.

255 is 45% of what number?
Answer:
if I'm not mistaking it's 15%
Answer:
x = 566.67
Step-by-step explanation:
We have, 45% × x = 255
or,
45/100
× x = 255
Multiplying both sides by 100 and dividing both sides by 45,
we have x = 255 ×
100/45
x = 566.67
If you are using a calculator, simply enter 255×100÷45, which will give you the answer.

What is the inequality represented by this graph? (pls help its worth 30 points and ill give brainliest if ur correct :D)
Step-by-step explanation:
We find the equation of the solid blue line:
The line decreases by 1 unit for every 3 units across.
=> Slope of line = -1/3.
Also the y-intercept is 1.
=> Line equation: y = -1/3 x + 1.
We see that the graph below this line is shaded.
Therefore all y-values below or on the line are represented by the graph.
=> y <= -1/3 x + 1.
The answer is y <= -1/3 x + 1.

N > 0 in number line
Answer:
The number 0 is not included; thus the number line indicates an open circle on 0, meaning 0 is not include in the solution.
Please check the attached graph.
Step-by-step explanation:
Given the inequality expression
N > 0
It is clear that the value of N is greater than 0, it means the solution contains all the positive real numbers greater than zero.
In other words:
[tex]N>0\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:N>0\:\\ \:\mathrm{Interval\:Notation:}&\:\left(0,\:\infty \:\right)\end{bmatrix}[/tex]
The number line containing the solution N > 0 is shown and attached below.
From the number line, it is clear that the number line would include all the numbers on the right-hand side of the 0 number.
The number 0 is not included; thus the number line indicates an open circle on 0, meaning 0 is not include in the solution.Please check the attached graph.
The perimeter of a rectangle is 24 inches. The length is 2 inches. Use the numbers below to complete an equation to solve for the width, w. Numbers may be used once, more than once, or not at all.
We want to find the width of a rectangle, we will find that the width is 10 inches.
Finding the width:So we know that the perimeter of a rectangle is just given by:
P = 2*(L + W)
Where L is the length and W is the width.
Here we know that:
P = 24 inches
L = 2 inches
Replacing that we get:
24 in = 2*(2 in + W)
(24in)/2 = (2 in + W)
12 in = 2 in + W
12 in - 2 in = 10 in = W
So the width is 10 inches.

Answer:
B=34.2
C=105.8
c=12.0
Step-by-step explanation:
find B using the sine rule
(sin40÷8)=(sinB÷7)
rearrange
sin B= (sin40x7)÷8
sin B=0.562
make sure to use your calculator
then press shift sin to find B
B= 34.2°
to the nearest tenth means to 1 decimal place
sum of angles in a triangle is 180
so 180-(40+34.2)=105.8°=C
use sine rule again to find c
(sin105.8÷c)=(sin40÷8)
rearrange
c= (sin 105.8x8)÷sin40
c=12.0
How are the hypotenuse and legs of a right triangle related?
Answer:
The sum of the legs is equal to the hypotenuse.
Step-by-step explanation:
I hope that this helps u..
Answer:
The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse (side c in the figure). The sides and the adjacent to the right angle are called legs (or catheti, singular: cathetus).

Monna and co-workers used radioactive isotopes to date sediments from lakes and estuaries. To verify this method they analyzed a 208Po standard known to have an activity of 77.5 decays/min, obtaining the following results
77.09, 75.37, 72.42, 76.84, 77.84, 76.69, 78.03, 74.96, 77.54, 76.09, 81.12, 75.75
Determine whether there is a significant difference between the mean and the expected value at αâ=â0.05.
Answer:
No significant difference between mean and Expected value
Step-by-step explanation:
Hypothesis
H0 : u = 77.5
H1: u is not equal to 77.5
Alpha = 0.05
Mean = Σxi/n
= 77.09+75.37+72.42+76.84+77.84, +76.69+78.03+74.96+77.54+76.09+81.12+75.75/12
= 919.74/12
= 76.645
We get the variance s² = xi² -n(barx)²/n-1
= 77.09²+75.37²...75.75²-12(76.645)²/11
When we solve this out
We get 4.3486818182
T test = barx - u/(s/√n)
= (76.645-77.5)/√4.3486818182/12
= -1.420293
T critical = Tn-1, alpha/2
= 2.200985
The test statistic is less than 2.201 so we accept the null hypothesis at 0.05 level of significance. And then conclude that there is No significant difference between mean and Expected value.
