How are the sun rays like mathematical rays

Ludmilka [50]

A ray in mathematics starts at a point and extends infinitely in one direction away from that point
it differes from a line because a line extend indefinitely in both directions

the sun ray starts from the sun and does not pass through the sun so it starts from a point (the sun's surface) and extends indefinitely into space unless it hits something (planets, black holes, endpoint)

The Lylian is one of several methods claimed to increase the likelihood of a baby girl. In a clinical trial, results could be an

nalin [4]

Answer:

$p_v =P(z>z_{calc})$

In order to establishing the success of the method we need to obtain a p value very low in order to reject the null hypothesis because we need enough evidence in favor of the alternative hypothesis, so then the best option would be:

f. 0.001

Step-by-step explanation:

We need to conduct a hypothesis in order to test the claim that one of several methods claimed to increase the likelihood of a baby girl so then the system of hypothesis are:

Null hypothesis: $p\leq 0.5$

Alternative hypothesis: $p > 0.5$

When we conduct a proportion test we need to use the z statisitc, and the is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

The p value for this case is given by:

$p_v =P(z>z_{calc})$

In order to establishing the success of the method we need to obtain a p value very low in order to reject the null hypothesis because we need enough evidence in favor of the alternative hypothesis, so then the best option would be:

f. 0.001

(- 1, 2) and (9, - 3)

taurus [48]

Answer:

-1/2 is your answer.

Step-by-step explanation:

The slope formula is (y_2 - y_1)/(x_2 - x_1)

The y's are -3 and 2, while the x's are 9 and -1.

(-3-2)/(9-(-1))=-5/10=

-1/2 is your answer.
