Answer: Choice A) Odd

The function sin(x) is odd because sin(-x) = -sin(x) for all values of x

As the example shows, sin(150) = 0.5 and sin(-150) = -0.5, so this shows sin(-150) = -sin(150).

Answer:

$df_{den}=df_{between}=N-K=17-3=14$ .

Step-by-step explanation:

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".

The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"

If we assume that we have $3$ groups (A,B,C) and on each group we have sample of size (6,5,6) respectively , on each group we can define the following formulas of variation:

$SS_{total}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x)^2$

$SS_{between}=SS_{model}=\sum_{j=1}^p n_j (\bar x_{j}-\bar x)^2$

$SS_{within}=SS_{error}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x_j)^2$

And we have this property

$SST=SS_{between}+SS_{within}$

The degrees of freedom for the numerator on this case is given by $df_{num}=df_{within}=k-1=3-1=2$ where k =3 represent the number of groups.

The degrees of freedom for the denominator on this case is given by $df_{den}=df_{between}=N-K=17-3=14$ .

And the total degrees of freedom would be $df=N-1=17 -1 =16$

On this case the correct answer would be 2 for the numerator and 14 for the denominator.

Answer:

MAKE MY ANSWER BRILLINEST PLEASE:)

Step-by-step explanation:

LET:

j = the points that Jessica scored

t = the points that Tina scored

Jessica scored 147 more points than Tina:

j = t + 1497

Together, Bradley and Harner scored 1601 points:

j + t = 1601

by solving the system of equations:

j = t + 147

j + t = 1601

we find

j = 856 points

t = 707 points

Jessica Bradley scored 856 point.

Tina Harner scored 707 points.
