Answer:

Step-by-step explanation:

The question is incomplete. The complete question is:

An insurance company reported that, on average claims for a certain medical procedure are $942. an independent organization constructed a 95% confidence interval of ($930, $950) for the average amount claimed for the particular medical procedure. what conclusion best evaluates the truthfulness of the number reported by the insurance company?

a) with 95% certainty, the average claim for this medical procedure is $942.

b) with 95% certainty, the average claim for this medical procedure is not $942.

c) the confidence interval is consistent with an average claim of $942 for this medical procedure

Solution:

Confidence interval is used to express how confident we are that the population parameter that we are looking for is contained in a range of given values. Looking at the given confident interval, the lower limit is $930 and the upper limit is $950. We can see that the population mean, $942 lies within these values. The correct option would be

c) the confidence interval is consistent with an average claim of $942 for this medical procedure

Answer:

The coordinates of B is (3, - 5)

Step-by-step explanation:

A(6, 1)

C(2, -7)

Coordinates of point B such that AB = 1/3 × BC

Hence we have;

AC = AB + BC = BC + \dfrac{1}{3} \times BC =  \dfrac{4}{3} \times BC

Therefore BC = 3/4 × AC

Hence, AB = 1/3 × BC = 1/3 × 3/4 × AC = 1/4 × AC

AC = √((6 - 2)² + (1 - (-7))²) = √(16 + 64) = √80 = 4·√5

AB = 1/4 × 4·√5 = √5

Therefore;

AB² = (x - 6)² + (y - 1)² = 5

Slope = (1 - (-7))/(6 - 2) = 2

Hence the y coordinate of B = -7 + sin(tan⁻¹(2)) ×√5 = -5

The x coordinate of B = 2 + cos(tan⁻¹(2)) ×√5 = 3

The coordinates of B = (3, - 5)

Murljashka [212]
The total amount that Chang will received from his wages is the product of his hourly wage times the number of hours he has worked (n). His total savings should not be less than $125. The equation that best describes the situation is, 
                                    45 + 7n ≥ 125
Solving for n in the inequality gives an answer of n≥11.42 hours. Thus, he needs to work for at least 12 hours.

Kristin is swimming in the ocean and notices a coral reef below her. The angle of depression is 35∘ and the depth of the ocean,
LenaWriter [7]

Answer:

Distance: 435.9 ft


Step-by-step explanation:

This is a right triangle shown in the picture.

To solve for x, we can use trigonometry.

The 35° angle's opposite side is 250 ft and the hypotenuse of the triangle is x (what we are seeking to find).

The ratio that relates opposite and hypotenuse is sine.


<em>We know that,</em>

sin(angle)=\frac{opposite}{hypotenuse}

<em>Thus we can write:</em>

sin(35)=\frac{250}{x}

<em>Cross multiplying and solving for x gives us:</em>

sin(35)=\frac{250}{x}\\x=\frac{250}{sin(35)}\\x=435.9


Second answer choice is right: 435.9 ft
