Find the critical value z Subscript alpha divided by 2zα/2 that corresponds to the given confidence level. 94%

1 answer:

4 0

The critical value is z=1.88.

We find this by first converting the percent confidence we want to a decimal: 94% = 94/100 = 0.94

We subtract that from 1 to find the alpha level:
1-0.94 = 0.06

Divide this by 2 (to find the area in each tail):
0.06/2 = 0.03

Subtract this from 1 again (because we want the area in the middle, not in each tail):
1 - 0.03 = 0.97

Using a z-table (http://www.z-table.com) we see that the closest to this in the table is at z = 1.88.

g A plane flying horizontally at an altitude of 2 miles and a speed of 550 mi/h passes directly over a radar station. Find the r

guapka [62]

Answer:

The rate at which the distance from the plane to the station is increasing is when it is 5 miles away from the station is 504 mi/h

Step-by-step explanation:

An illustrative diagram for the scenario is shown in the attachment below.

In the diagram, y represent the altitude, z is the horizontal distance from the plane to the station and x is the distance from the plane to the station.

From the Pythagorean theorem, we can write that

x² = y² + z²

Differentiate this with respect to time t

That is,

$\frac{d}{dt}(x^{2}) = \frac{d}{dt}(y^{2}) + \frac{d}{dt}(z^{2})$

= $2x(\frac{dx}{dt}) = 2y(\frac{dy}{dt}) + 2z(\frac{dz}{dt})$

$x(\frac{dx}{dt}) = y(\frac{dy}{dt}) + z(\frac{dz}{dt})$

The rate at which the distance from the plane to the station is increasing is $\frac{dx}{dt}$

$\frac{dy}{dt}$ is the rate at which the altitude is increasing, since the altitude is 2, that is constant, $\frac{dy}{dt} = 0$ .

$\frac{dz}{dt}$ is the rate at which the horizontal distance is increasing which is the speed, that is, $\frac{dz}{dt} = 550 mi/h$

$y = 2$ and $x = 5$

Now, we will determine z when x = 5.

From x² = y² + z²

5² = 2² + z²

25 = 4 + z²

z² = 25-4

z² = 21

z =√21

Putting all the values into the equation

$x(\frac{dx}{dt}) = y(\frac{dy}{dt}) + z(\frac{dz}{dt})$

$5(\frac{dx}{dt}) = 2(0) + \sqrt{21} (550)$

$5(\frac{dx}{dt}) = \sqrt{21} (550)$

$\frac{dx}{dt} = \frac{\sqrt{21} (550)}{5}$

$\frac{dx}{dt} = 504 mi/h$

Hence, the rate at which the distance from the plane to the station is increasing is when it is 5 miles away from the station is 504 mi/h.

Find the missing segment in the image.

vladimir1956 [14]

Answer:

? = 54.

Step-by-step explanation:

According to the AA Theorem, the two triangles are similar.

$\frac{35}{65} =\frac{63}{? + 63}$

$\frac{7}{13} =\frac{63}{? + 63}$

7(? + 63) = 63 * 13

? + 63 = 9 * 13

? + 63 = 117

? = 54

Hope this helps!

Answer: About 14
Work: 200 divided by 15 (200/15) is 13.3 repeating. That’s not a solid number so you have to round up. He will have extra money but if you don’t round up he won’t have enough
