Is the mean height for all adult American males between the ages of 18 and 21 now over 6 feet? Let Î¼ represent the population m

SIZIF [17.4K]

Answer:

A. H0: Î¼ = 6 vs. Ha: Î¼ > 6

H0 : µ = 6 vs. Ha : µ > 6

Step-by-step explanation:

Null hypotheses state that there is no difference between a parameter and a specific value.

Alternative hypotheses states a specific difference between a parameter and a specific value.

Null hypotheses is represented as H0

Alternative hypotheses is represented as Ha.

From the question,

The claim is this "Is the mean height for all adult American males between the ages of 18 and 21 now over 6 feet?" The claimed statement represent the Alternative hypotheses.

So, the alternative hypotheses is:

Ha: Î¼ > 6

While the null hypotheses is:

H0: Î¼ = 6

The length of the hypotenuse of the right triangle is 25 cm, the length of one of the legs is 10 cm. What is the length of the s

Anna007 [38]

Answer:

21 cm

Step-by-step explanation:

Call the triangle ABC, with the right angle at B, the hypotenuse AC=25, and the given leg AB=10. The altitude to the hypotenuse can be BD. Since the "other leg" is BC, we believe the question is asking for the length of DC.

The right triangles formed by the altitude are all similar to the original. That means ...

AD/AB = AB/AC . . . . . . ratio of short side to hypotenuse is a constant

Multiplying by AB and substituting the given numbers, we get ...

AD = AB²/AC = 10²/25

AD = 4

Then the segment DC is ...

DC = AC -AD = 25 -4

DC = 21 . . . . . centimeters

Answer:

LP = 18

Step-by-step explanation:

Given that,

In ΔLPN,

LQ = 6, LM = 11 and MN = 22

We need to find the length of LP.

As QM ║PN, let QP = x

$\dfrac{LQ}{LP}=\dfrac{LM}{LN}\\\\\dfrac{6}{6+x}=\dfrac{11}{11+22}\\\\\dfrac{6}{6+x}=\dfrac{11}{33}\\\\198=66+11x\\\\198-66=11x\\\\132=11x\\\\x=12$

LP = 6+x

= 6+ 12

= 18

Hence, the length of LP is 18.
