Consider the right triangle. What is the length of the hypotenuse? Please help!

Luba_88 [7]

Answer:

The answer to your question is: hypotenuse = 53 m

Step-by-step explanation:

Data

Opposite leg = 28

Adjacent leg = 45

hypotenuse = ?

Pythagorean theorem

$c^{2} = a^{2} + b^{2} \\$

$c^{2} = 28^{2} + 45^{2}$

$c^{2} = 784 + 2025$

c² = 2809

c = 53 m

Answer:

The length of QS = 8

Step-by-step explanation:

From the above question:

Δ Q R S ≅ Δ T U V

Q S = 3 v + 2 , and T V = 7 v − 6 , enter the lengths of QS

Hence:

Step 1

We solve for v

QS = TV

3v + 2 = 7v - 6

Collect like ters

2 + 6 = 7v - 3v

8 = 4v

v = 8/4

v = 2

Step 2

Solving for Q S

Q S = 3 v + 2

v = 2

QS = 3(2) + 2

QS = 6 + 2

QS = 8

The length of QS = 8

Consider the following hypothesis test: H 0: 20 H a: < 20 A sample of 50 provided a sample mean of 19.4. The population stand

goblinko [34]

Answer: p-value is 0.016.

Step-by-step explanation:

Since we have given that

$H_0:\mu=20\\\\H_a:\mu$

Sample mean = 19.4

Sample size n = 50

Standard deviation = 2

We need to find the test statistic value which is given by

$z=\dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\\\z=\dfrac{19.4-20}{\dfrac{2}{\sqrt{50}}}\\\\\\z=\dfrac{-0.6}{0.28}\\\\z=-2.14$

p-value is given by

$P(Z>Z_{critical})\\\\=P(Z>-2.14)\\\\=0.016$

Hence, p-value is 0.016.
