Which graph represents an odd function? Answer by using: A, B, C, or D for each graph.

vladimir1956 [14]

Answer: The correct option is C.

Explanation:

A function is called an odd function if,

$f(-x)=-f(x)$

It means if the points are in the form of (x,y) then (-x,-y) is also in the graph.

Reason for correct option:

In option C, a point (1,2),

It means,

$f(1)=2$

And we have another point (-1,-2).

$f(-1)=-f(1)=-2$

The other points are (2,3),(-2,-3),(3,-1),(-3,1),(4,0),(-4,0). Therefore the function is an odd function.

Reason for incorrect option:

In option A, a point is (1,3), therefore the value of function at x = -1 should be -3.

But the value of function is 1 at x=-1, therefore it is not an odd function.

In option B, a point is (1,0), therefore the value of function at x = -1 should be 0.

But the value of function is -3 at x=-1, therefore it is not an odd function.

In option D, a point is (1,-1), therefore the value of function at x = -1 should be 1.

But the value of function is -1 at x=-1, therefore it is not an odd function.

Assume a researcher recruits 150 African American and Caucasian individuals taking warfarin to determine if there is a differenc

Anettt [7]

Answer:

Z=11.0

Step-by-step explanation:

Let Caucasian individuals be the population 1 and African American be the population 2. So, we are given that

n=150

n1=75

mean1=xbar1=6.1.

standard deviation1=S.D1=σ1=1.1.

Variance1=V(x1)=σ1²=1.1²=1.21.

n2=75.

mean2=xbar2=4.3.

standard deviation2=S.D2=σ2=0.9.

Variance2=V(x2)=σ2²=0.9²=0.81.

The z-statistic is

$Z=\frac{xbar1-xbar2}{\sqrt{\frac{V(x1)}{n1}+ \frac{V(x2)}{n2} } }$

$Z=\frac{6.1-4.3}{\sqrt{\frac{1.21}{75}+ \frac{0.81}{75} } }$

$Z=\frac{1.8}{\sqrt{0.0161+ 0.0108 } }$

$Z=\frac{1.8}{\sqrt{0.0269 } }$

$Z=\frac{1.8}{0.164 } }$

Z=10.97

Z=11.0

So, the z value obtained while calculating the test statistic is approximately 11.0.

Examine the intersection of these lines:

Leto [7]

Answer:

∠B and ∠F

∠F and ∠E . . . already listed in the problem statement, so may not be considered an "other pair"

Step-by-step explanation:

∠C and ∠F are vertical angles, so are congruent. Then any angle complementary to one of those will also be complementary to the other.

Likewise, ∠B and ∠E are vertical angles and congruent. Any angle complementary to one of them will also be complementary to the other. Here, ∠E and ∠F are listed as complementary, so we know ∠B and ∠F will be also.
