24 and 32 are the given lengths of a right triangle with the unknown length (x) being 40, how do I tell if its a leg or the hypo

tenuse?

By the Pythagorean theorem

a^2=b^2+c^2⇒

40^2=24^2+32^2\\1600=1600

So a triangle with these sides exists

In a right triangle, the largest side is a hypotenuse, so the side with length 40 is a hypotenuse.

P.S. Hello from Russia and sorry for my bad english :^)

Step-by-step explanation:

If the sum of the squares of 24 and 32 are equal to square of 40, then it is a hypotenuse.

Let us check.

{24}^{2}  +  {32}^{2}  = 576 + 1024 = 1600...(1) \\  {40}^{2}  = 1600...(2) \\ from \: equations \: (1) \: and \: (2) \\  {24}^{2}  +  {32}^{2}  = {40}^{2}  \\  \therefore \: 24 \: and \: 32 \: are \: lengths \: of \: legs \\ and \: 40 \: is \: the \: length \: of \: hypotenuse.

Brand name producers of aspirin claim that one advantage of their aspirin over generic aspirin is that brand name aspirin is muc
11Alexandr11 [23.1K]

Answer:

Step-by-step explanation:

The claim here is that the brand name aspirin is more consistent in the amount of active ingredient used than the generic aspirin.

This is a test of 2 independent groups. The population standard deviations are not known. Let μ1 be the mean amount of active ingredients in brand name aspirin and μ2 be the mean amount of active ingredients in generic name aspirin

The random variable is μ1 - μ2 = difference in the mean amount of active ingredients between the brand name and generic aspirin

We would set up the hypothesis.

The null hypothesis is

H0 : μ1 ≥ μ2 H0 : μ1 - μ2 ≥ 0

The alternative hypothesis is

H1 : μ1 < μ2 H1 : μ1 - μ2 < 0

This is a left tailed test

Since sample standard deviation is known, we would determine the test statistic by using the t test. The formula is

(x1 - x2)/√(s1²/n1 + s2²/n2)

From the information given,

x1 = 325.01

x2 = 323.47

s1 = 10.12

s2 = 11.43

n1 = 200

n2 = 180

t = (325.01 - 323.47)/√(10.12²/200 + 11.43²/180)

t = 1.24

1.237877

The formula for determining the degree of freedom is

df = [s1²/n1 + s2²/n2]²/(1/n1 - 1)(s1²/n1)² + (1/n2 - 1)(s2²/n2)²

df = [10.12²/200 + 11.43²/180]²/[(1/200 - 1)(10.12²/200)² + (1/180 - 1)(11.43²/180)²] = 1.53233946713/0.00537245359

df = 285

We would determine the probability value from the t test calculator. It becomes

p value = 0.108

Since alpha, 0.025 < than the p value, 0.108, then we would fail to reject the null hypothesis. Therefore, at 2.5% level of significance, these data support the brand name producers claim
