Slow response times by paramedics, firefighters, and policemen can have serious consequences for accident victims. In the case o
kramer

Answer:

a)

H_0: \pi\geq0.78\\\\H_a: \pi

b) The Type I error occurs when we reject a null hypothesis that is actually true. In this case, it means we conclude that the arrival time have improved, when it didn't.

The Type II error occurs when we accept a null hypothesis that is actually false. In this case, although the arrival times have really improved, the evidence from the sample was not enough to show that improvement.

c) In this case, the Type I error is more serious, because it gives the wrong impression of improvement and no further actions will be taken to reduce the times.

Step-by-step explanation:

a) If you want to determine if the responders are arriving within 8 minutes of the call more often, you have to evaluate the proportion of accidents in which the arrival time is less than 8 minutes and compare it with the known proportion of π=0.78.

The sample parameter "p: proportion of accidents with arrival time of 8 minutes or less" will be used to test the hypothesis.

The null and alternative hypothesis will be:

H_0: \pi\geq0.78\\\\H_a: \pi

Howard is standing 109 yards from the bottom of a water reservoir. He estimates that the angle of elevation to the top of the wa
pav-90 [236]

Answer:

70.1 yards

Step-by-step explanation:

See the attached diagram.

Let AC is the reservoir with A as the bottom and C is the top.

Now, B is the position of Howard which is 109 yards from A i.e. AB = 109 yards.

Again, the angle elevation from B to C is 50 degrees.

So, ∠ ABC = 50°  

Now, \cos 50 = \frac{AB}{BC} = \frac{109}{x}

⇒ x = 109 cos 50 = 70.1 yards.

Therefore, the distance between the top of the reservoir and Howard i.e. BC is equal to 70.1 yards. (Answer)

Z2-y2=x2 solve for z2 (literal equation)
expeople1 [14]

Answer:

z² = x² + y²

Step-by-step explanation:

Given

z² - y² = x² ( isolate z² by adding y² to both sides )

z² = x² + y²

John who is 5 ft tall is standing 20 feet away from a tree, and you measure the angle of elevation to be 38∘. How tall is the tr
fenix001 [56]

Answer:

The tree is 20.6 ft tall.

Step-by-step explanation:

Please check the attached graph.

From the diagram, it is clear that John is 5 ft tall is standing 20 feet away from a tree, making an angle of elevation to be 38⁰.

The diagram makes a right-angled triangle.

  • Given the angle = Ф = 38⁰
  • Adjacent = a = 5 ft
  • Opposite = b = 20 ft
  • Hypotenuse = Tree length = c  ?

Pythagorean Theorem:

For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:

\:c=\sqrt{a^2+b^2}

substituting a=5, b=20

c=\sqrt{5^2+20^2}

c=5\sqrt{17}

c=20.6 ft

Thus, the tree is 20.6 ft tall.
