g If there is a very weak correlation between two variables, then the coefficient of determination must be
Answer:
very close to or equal to zero
Explanation:
Correlation coefficients refer to the degree of relationship between two exclusive variables.
A weak correlation means that a change in one variable does not significantly affect or cause any reaction with the second variable.
For example, if the prices of coffee and the price of ballons are observed in the same period and found to have a correlation of +0.00006. This means that there is little or no correlation, or relationship, between the two variables. Weak relationships are usually between -0.1 and +0.1
Correlation coefficients can also be positive or negative.
It is positive if both factors seem to move in the same direction. As an example, if the price of stocks for Apple and Microsoft change in the same direction in the same period, they are said to have a positive correlation coefficient.
On the flip side, the correlation coefficient will be negative if the price of one stock moves upwards whilst the other moves downwards. A perfect negative relationship would read -1.

Find each difference 1 1/2 + (-1/2)
Answer:
1 1/2 + (-1/2) is also 1 1/2 - 1/2.
the result is 1 whole, and 1 whole is also the difference between 1 1/2 and 1/2.
Say you have half of a cheese piece, but your friend has 1 whole cheese piece plus half of a cheese piece.
He/She has 1 more cheese piece than you, right? That's the difference between you and your friend's cheese. 1 whole.

1. If a student's course grade was a B, what is the probability that a randomly selected student did at least 30 minutes of homework at night?
2. Are the events "did at least 30 minutes of homework l" and "course grade is a B" independent? Explain your answer.
9514 1404 393
Answer:
0.70yesStep-by-step explanation:
1. P(≥30 | B) = P(≥30 & B)/P(B)
P(≥30 | B) = 0.21/0.30 = 0.70
The probability that a B student did at least 30 minutes of homework is 0.70.
__
2. The probability that any student did at least 30 minutes of homework is shown in the column a the right end of the table: 0.70. This is the same as the probability that a B student did at least 30 minutes of homework. That is ...
P(≥30 | B) = P(≥30)
Hence, the events "at least 30 minutes of homework" and "B student" are independent.

Marshall can buy 5 T-shirts for $55.
If each shirt costs the same amount, what is the cost of 3 T-shirts?
The cost of 3 T-shirts is $
.
Answer:
$33
Step-by-step explanation:
55 divided by 5 is 11, so each shirt costs $11. So that means 3 shirts would be $33.
Answer:
$33
Step-by-step explanation:
$33 because 55 dollars divided by 5 shirts is 11 dollars so multiply 11 by 3 and the answer is $33
Over which interval of the domain is function h decreasing?
The interval of the domain of the considered function for which the function is decreasing is none. The function is strictly increasing: Option D: The function is increasing only.
When do we say that a function is decreasing?Suppose that the function is y = f(x)
If for an interval I, when x increases meanwhile staying in the interval I, the function's output decreases (or can stay same), then we say that the function is decreasing in the interval I.
This interval I was of values that x can take for this function, which is the domain of the considered function, so we say:
y = f(x) is decreasing function in an interval I if:
[tex]f(x+\delta) \leq f(x) \: \forall x \in I : x+\delta \in I[/tex]
If we have:
[tex]f(x+\delta) < f(x) \: \forall x \in I : x+\delta \in I[/tex], then the function is called strictly decreasing in the interval I.
Similarly, there increasing( [tex]f(x+\delta) \geq f(x) \: \forall x \in I : x+\delta \in I[/tex] ) and strictly increasing([tex]f(x+\delta) > f(x) \: \forall x \in I : x+\delta \in I[/tex] ) functions.
For this case, the function is:
[tex]h(x) = \left \{ {{2^x, x < 1} \atop \: \atop {\sqrt{x+3}, x \geq 1}} \right.[/tex]
The function is differentiable in either side of 1.
Sign of rate of function at a point tells whether its increasing or decreasing.
For x < 1:[tex]h'(x)= 2^x ln(2)[/tex]
We know that:
[tex]2^x > 0 \: \rm \forlall x \in \mathbb R[/tex]
And [tex]ln(2) \approx 0.69 > 0[/tex]
Thus, [tex]h'(x)= 2^x ln(2) > 0 \: \forall x \in \mathbb R[/tex]
So, rate is positive, the function is strictly increasing for this case.
For x > 1:[tex]h'(x) = \dfrac{1}{2\sqrt{(x+3)}}[/tex]
For all x > 1, [tex]\sqrt{x+3} > 0[/tex], and so as h'(x)
So rate is positive and therefore strictly increasing for this case too.
For x = 1:[tex]h(1+\delta) - h(1)= \sqrt{1+\delta + 3} - \sqrt{1+3} = \sqrt{4+\delta} - \sqrt{4} > 0 \forall \delta > 0[/tex]
So rate of the considered function is positive,so function is strictly increasing all over the domain.
Thus, the interval of the domain of the considered function for which the function is decreasing is none. The function is strictly increasing: Option D: The function is increasing only.

Eliza volunteers at a nearby aquarium where she tracks the migratory patterns of humpback whales from their feeding grounds to their breeding grounds. She recorded the distance traveled by the whales each day for a 7-day period at the start of their migration. Based on Eliza's data, about how long will it take the humpback whales to travel the 3,100 miles to their breeding grounds?
Answer:
Step-by-step explanation:
This is a very confusing, or otherwise incomplete question. The data Eliza recorded from her study at the aquarium is not given, and thus we wouldn't be able to peg a number as the time it took to travel 3100 miles by the whales.
There are lots of date missing, the total number of whales the distance each whale traveled and even, how long each traveled. These missing has essentially rendered the question unsolvable

A. No, because 4 miles is yards, and 40 times around the route is yards, which is less than 4 miles.
B. Yes, because 4 miles is yards, and 40 times around the route is yards, which is the greater than 4 miles.

Answer:
[tex]y=9.75x[/tex]
Step-by-step explanation:
Your y is always the dependent variable, or the value that changes when another value changesSo which one depends on the other, between the 'money for school charity' and 'number of lawns mowed'? the money for charity depends on how lawns are mowed, so this is yNow we have y, and we already know it depends on the number of loans mowed, so number of lawns mowed is xSo an equation in the form [tex]y=mx+b[/tex] is a slope-intercept form where m is the slope and b is just a constant number, in this case b is 0.so we have [tex]y=mx[/tex]Now the slope m is interesting because it is the "amount of change"Let's ask ourselves, when Donny mows one lawn he gets, 9.75 dollars, and when he mows 2 lawns he gets 19.5 dollarsThe amount change here is 9.75, so that's our slope m is 9.75so the equation is [tex]y=9.75x[/tex]Find the slope of the line contains P1 and P2
Interpret this slope
P1=(-1,3 and p2 =(5,-1)
Answer:
[tex]m = -\frac{2}{3}[/tex]
Step-by-step explanation:
Given
[tex]P_1 = (-1,3)[/tex]
[tex]P_2 = (5,-1)[/tex]
Required
Determine and interpret slope
Slope is calculated using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (-1,3)[/tex]
[tex](x_2,y_2) = (5,-1)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{-1 - 3}{5 - (-1)}[/tex]
[tex]m = \frac{-1 - 3}{5 +1}[/tex]
[tex]m = \frac{-4}{6}[/tex]
[tex]m = -\frac{2}{3}[/tex]
The above slope is negative and it implies that x increases when y decreases and vice versa.
Which of the following is the slope of the line passing through each pair of points?
Point 1: (7,-4)
Point 2: (4,8)
Answer:
- 4
Step-by-step explanation:
Formula of slope:
m = ( [tex]y_{2}[/tex] - [tex]y_{1}[/tex] ) / ( [tex]x_{2}[/tex] - [tex]x_{1}[/tex] )
m = [8 - ( - 4)] / (4 - 7) = (8 + 4) / ( - 3) = - 4

A T-shirt shop charges a $25 set-up fee for a new T-shirt design and $6 for every shirt ordered. Which equation best represents the linear relationship between x, the number of shirts ordered, and y, the total cost of a T-shirt order?
Group of answer choices
A:He started on page 30 and read 6 pages each day.
B:He started on page 30 and read 8 pages each day.
C:He started on page 20 and read 12 pages each day.
D:He started on page 20 and read 10 pages each day.
Answer:
[tex]y = 25 + 6x[/tex]
Step-by-step explanation:
The given options are not in anyway related to the question. So, I will do away with them.
Given
[tex]Set-up\ Fee = \$25[/tex]
[tex]Per\ Shirt = \$6[/tex]
Required
Determine the linear relationship
Let
y represents the total cost
x represents the number of shirts
The relationship between x and y is:
[tex]y = Setup\ Fee + Amount\ Per\ Shirt * x[/tex]
This gives:
[tex]y = 25 + 6* x[/tex]
[tex]y = 25 + 6x[/tex]

Part A: The Sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the Sun produce in 3.25 ⋅ 103 seconds? Express your answer in scientific notation and show your work. (5 points)
Part B: Which is the more reasonable measurement of the distance between the tracks on a railroad:
1.435 ⋅ 10−3 mm or 1.435 ⋅ 103 mm? Justify your answer. (5 points)
5914 1404 393
Answer:
A) 1.3×10^37 ergs
B) 1.435×10^3 mm
Step-by-step explanation:
A) The amount of energy will be the product of the energy rate and time:
(3.9×10^33 ergs/s)×(3.25×10^3 s) =12.675×10^(33+3) ergs
= 1.2675×10^(1+36) ergs
= 1.2675×10^37 ergs ≈ 1.3×10^37 ergs
The mantissa of the result is the product 3.9×3.25, adjusted to have one digit left of the decimal point. The exponent of the result is the sum of the exponents of the factors, adjusted by 1 to match the adjustment in the mantissa.
The final value should be rounded to 2 significant figures, reflecting the precision of the sun's energy production.

B) A millimeter is a small fraction of an inch. 10^-3 mm is a small fraction of the width of a human hair, so 1.435×10^-3 mm is not a reasonable estimate of the distance between railroad tracks.
On the other hand, 1.435×10^3 mm is 1.435 m, almost 56.5 inches. This is a much more reasonable measurement of the distance between railroad rails.
1.435×10^3 mm is more reasonable
