Answer:

x coordinate is negative

y coordinate is positive

Step-by-step explanation:

We know that

\pi=180

Hence

\frac{3\pi}{4}=\frac{3*180}{4}

\frac{3\pi}{4}=3*45=135

Hence our angle lies in the second quadrant. Second quadrant is enclosed by the negative x axis and positive y axis.

In second quadrant, we have negative value if x coordinate and positive value of y coordinate.

3pi/4 is 135 in degrees.  A 135-degree angle lies in quadrant 2.  In quadrant 2, the x values are negative and the y values are positive.

1. Which function represents exponential decay?
MatroZZZ [7]

Answer:

y= 7^-t

Step-by-step explanation:

Equation for exponential decay:

An equation represents exponential decay if a term between 0 and 1 is elevated to the independent variable.

In this question:

First option 4 is elevated, so not exponential decay.

Second option:

7^{-t} = \frac{1}{7^t} = (\frac{1}{7})^{t}

0 < \frac{1}{7} < 1, thus, the second option represents exponential decay.

Seth has one less than twice the number of compact discs (CDs) that Jason has. Raoul has 53 more CDs than Jason. If Seth gives J
ELEN [110]
S = 2J - 1
R = J + 53
S - 25 = J + 25...S = J + 50

2J - 1 = J + 50
2J - J = 50 + 1
J = 51 <===Jason has 51 CD's

R = J + 53
R = 51 + 53
R = 104 <===Raoul has 104 CD's

S = 2J - 51
S = 2(51) - 1
S = 102 - 1
S = 101 <===Seth has 101 CD's

Which of the following statements is true in a one-way ANOVA? a. The critical value of the test will be a value obtained from th
Musya8 [376]

Answer:

d) All of the above

Step-by-step explanation:

A one way analysis of variance (ANOVA) test, is used to test whether there's a significant difference in the mean of 2 or more population or datasets (minimum of 3 in most cases).

In a one way ANOVA the critical value of the test will be a value obtained from the F-distribution.

In a one way ANOVA, if the null hypothesis is rejected, it may still be possible that two or more of the population means are equal.

This one way test is an omnibus test, it only let us know 2 or more group means are statistically different without being specific. Since we mah have 3 or more groups, using post hoc analysis to check, it may still be possible it may still be possible that two or more of the population means are equal.

The degrees of freedom associated with the sum of squares for treatments is equal to one less than the number of populations.

Let's say we are comparing the means of k population. The degree of freedom would be = k - 1

The correct option here is (d).

All of the above
