A medical researcher wishes to investigate the relationship between hours exercised and weight lost. The researcher randomly samples 50 people on an exercise program and asks them to report how many hours they have exercised on average over the last 6 weeks and how many pounds they have lost. The researcher runs a correlation and finds a test statistic of .34. Knowing that the critical value is .279, what should the researcher conclude
Answer:
The researcher will conclude that there is a correlation between the number of hours worked out and the amount of pounds lost by people on the exercise program
Step-by-step explanation:
Here, we want to state what the conclusion of the researcher should be:
From the last part of the question, we can see that the test statistic is greater than the critical value
So what do we do in a case like this?
We can see that the researcher is trying to see if there is a correlation between hours worked out and the number of pounds lost over a specific period of time.
Now, let us form the null hypothesis;
The null hypothesis here H0 is that we do not have a correlation between number of hours spent working out and the amount of pounds lost
The alternative hypothesis here H1 is that there is a correlation between the number of hours spent working out and the amount of pounds lost
Since we have the value of the test statistic greater than the critical value, we reject the null hypothesis and accept the alternative hypothesis
So therefore, the researcher will conclude that there is a correlation between the number of hours worked out and the amount of pounds lost by people on the exercise program

Answer:
y=3x-1
Step-by-step explanation:
First, we must find the slope of the equation. To do that we take two ordered pairs from the graph.
(2,5) (10,29)
The equation for slope is m=y2-y1/x2-x1
m=29-5/10-2
m=24/8
m=3
Now, we will find the variable B.
5=3(2)+b
5=6+b
-1=b
That's how we get the equation!
y=3x-1
Answer:y= 3x-1
Step-by-step explanation:
m= y2-y1/ x2-x1=
29-5/10-2=3
Now,use: y-y1= m(x-x1)
y-5=3( x-2)
y= 3x-1
A sample of 11 students using a Ti-89 calculator averaged 31.5 items identified, with a standard deviation of 8.35. A sample of 12 students using a Ti-84 calculator averaged 46.2 items identified, with a standard deviation of 9.99. Can we conclude that the mean number of times identified with the Ti-84 calculator exceeds that of the Ti-89 calculator by more than 1.80
Answer:
We reject H₀, with CI = 90 % we can conclude that the mean numbers of times identified with Ti-84 does not exceed that of the Ti-89 by more than 1,80
Step-by-step explanation:
Ti-89 Calculator
Sample mean x = 31,5
Sample standard deviation s₂ = 8,35
Sample size n₂ = 11
Ti-84 Calculator
Sample mean y = 46,2
Sample standard deviation s₁ = 9,99
Sample size n₁ = 12
t(s) = ( y - x - d ) / √s₁²/n₁ + s₂²/n₂
t(s) = 12,9 / √(99,8/12) + (69,72/11)
t(s) = 12,9 / √8,32 + 6,34
t(s) = 12,9 / 3,83
t(s) = 3,37
Test Hypothesis
Null Hypothesis H₀ y - x > 1,80
Altenative Hypothesis Hₐ y - x ≤ 1,80
We have a t(s) = 3,37
We need to compare with t(c) critical value for
t(c) α; n₁ +n₂-2 df = 12 +11 -2 df = 21
If we choose CI = 95 % then α = 5 % α = 0,05
From t-student table
t(c) = 1,72
t(s) = 3,37
t(s) >t(c)
t(s) is in the rejection region therefore we accept Hₐ with CI = 95 %

Classify the following statement as true or false.
Every quadratic function either has a maximum or minimum value.
A. False, became a quadratic equation does not have a maximum value.
B. True, because the graph of quadratic function is a curve that is either increasing or decreasing.
C. True, because the graph of a quadratic function is a parabola that either opens downwards or upwards.
D. False, because a quadratic function does not have a minimum value.
Answer:
C
Step-by-step explanation:
If the parabola opens upward, it has a minimum.
If it opens downwards, it has a maximum.
Every quadratic function either has a maximum or minimum value is true, because the graph of a quadratic function is a parabola that either opens downwards or upwards.
What is Quadratic Function?A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two. Since the highest degree term in a quadratic function is of the second degree, therefore it is also called the polynomial of degree 2.
What are properties of quadratic functions?Three properties that are universal to all quadratic functions:
1) The graph of a quadratic function is always a parabola that either opens upward or downward (end behavior).
2) The domain of a quadratic function is all real numbers.
3) The vertex is the lowest point when the parabola opens upwards; while the vertex is the highest point when the parabola opens downwards.
According to the question
Every quadratic function either has a maximum or minimum value.
As per the properties of Quadratic Function
This statement is true as
i> the graph of a quadratic function is a parabola
ii> The vertex is the lowest point when the parabola opens upwards or the vertex is the highest point when the parabola opens downwards.
Hence, Every quadratic function either has a maximum or minimum value is true, because the graph of a quadratic function is a parabola that either opens downwards or upwards.

The product of a number and -7 amounts to seven times the sum of that number and 20. Find the number.
Answer: -10
Step-by-step explanation:
If you put it in an equation it would be -7x=7(x+20). You would then -7x to both sides to get -14x=140. Just divide -14 on both sides to isolate x. This equates to -10. If you put -10 back into the equation then it says that 70 is 7 times larger than 10. Which it is.

Rectangle LMNP was dilated using the rule DP,3. Which statements are true? Check all that apply. The length of line segment M'N' is 18 units. The length of segment M'N' is 14 units. The dilation is a reduction. The dilation is an enlargement. The scale factor is One-third. The scale factor is 3.
The given rule of the dilation indicates that the scale factor is 3 which is
larger than one, therefore, given an enlarged image.
The correct options are;
The length of line segment M'N' is 18 unitsThe dilation is an enlargementThe scale factor is 3Methods by which the scale factor is obtainedPlease find attached the possible diagram of rectangle LMNP obtained from a similar question posted online;
L'M' = 12
LM = 4
MN = 6
The rule of the dilation of rectangle LMNP = [tex]D_{p, \, 3}[/tex]
L'M' = 3 × LM
Therefore;
The image following the dilation of the preimage LMNP, which is rectangle L'M'N'P' is larger than LMNP
Therefore;
The dilation is an enlargementThe scale factor is the number with which the preimage dimension is multiplied to get the image, which is 3
The scale factor is 3M'N' = 3 × MN

As an estimation we are told €4 is $5. What is the conversion rate from € to $? Give your answer rounded to 2 DP.
Answer:
$1.25/€
Step-by-step explanation:
€4 = $5
Divide both sides by €4.
€4/€4 = $5/€4
1 = $5/€4 = $1.25/€
Since $1.25/€ is equal to one, multiplying a number of euros by it will not change the value of the number. It will convert it from euros to dollars.
Answer: $1.25/€

Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = x2 + x + 1
Axis of symmetry: x = -0.5; Vertex: (-0.5, -0.75); f(x) = x2 - x + 1
Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = -x2 + x
Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = x2 + 2x + 1
Graph of the question is missing so I have attached it
Answer:
Option A: Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = x2 + x + 1
Step-by-step explanation:
1) The axis of symmetry of quadratic graph is the vertical line that divides the graph curve into two congruent halves. In this case, it is: x = -0.5
2) Vertex is the point at which the graph curve changes direction or simply coordinates of the crest or trough of the curve.
The graph given has a trough with the coordinates: x = -0.5, y = 0.75. This is (-0.5, 0.75)
3) The roots of a quadratic equation are the points where the curve crosses the x-axis. In this case, it doesn't cross and so we have imaginary roots.
Now, formula for line of symmetry is; x = -b/2a
Thus; -b/2a = -0.5 or -b/2a = -1/2
Thus, b = 1 and a = 1
Our first and second terms will now be;
x² + x
Looking at the options, the only one with x² + x as it's first 2 terms is option A.
Thus, the complete equation will be x² + x + 1
