What is the differences between Mathematics and Science

miss Akunina [59]

I’m not sure if you’re looking for a specific answer, but on a broad spectrum science is typically just applied mathematics. Math can be incorporated into all sciences, especially physics. On occasion, science can also be included in math, like when using derivatives to find the acceleration of a moving object. All in all though, the two subject are very connected.

MaRussiya [10]

Answer:

The null hypothesis is $H_0: p = 0.22$

Step-by-step explanation:

According to the Centers for Disease Control and Prevention, the proportion of U.S. adults age 25 or older who smoke is .22

This means that at the null hypothesis, it is tested if the proportion is in fact 0.22, that is:

$H_0: p = 0.22$

A researcher suspects that the rate is lower among U.S. adults 25 or older who have a bachelor's degree or higher education level.

At the alternative hypothesis, it is tested if the proportion is lower than 0.22, that is:

$H_1: p < 0.22$

FACTOR COMPLETELY<br><br> x^2-7x+7y-y^2

shtirl [24]

Given: ${x}^{2} - 7x + 7y - {y}^{2}$

Now factoring them,

$= > (x - y)(x + y) - 7(x - y)$

$= > (x - y)(x + y - 7)$

Therefore, the answer to the question is $(x - y)(x + y - 7)$
