Assume for a given study that the null hypothesis asserts the expected value of a phenomenon is 10. A research study results in

a 95% confidence interval reported as [7.142, 9.865]. What decision would you make based on this confidence interval

Answer:

I would reject the null hypothesis because it falls outside of the 95% confidence interval.

nasty-shy [4]

Answer:

$150.00

Step-by-step explanation:

Tenía $ 5.00

Mi mamá me dio $ 10.00 mientras que mi papá me dio $ 30.00.

Esto significa que luego tengo:

5 + 10 + 30 = $ 45.00

Mi tía y mi tío me dieron 100.00.

Entonces tuve:

45 + 100 = $ 145.00

Tenía otros $ 5.00.

Esto significa que en conjunto tuve:

145 + 5 = $ 150.00

Anarel [89]

*Correct Question:

Based on the similar triangles shown below, Theodore claims that ∆TUV is transformed to ∆WXY with a scale factor of 3/2. Is Theodore correct?

A. Yes, the triangles are similar with a scale factor of 3/2.

B. No, the triangles are similar with a scale factor of 2/1.

C. No, the triangles are similar with a scale factor of 2/3.

D. No, the triangles are similar with a scale factor of 4/3.

Answer:

C. No, the triangles are similar with a scale factor of 2/3.

Step-by-step explanation:

∆TUV is the original triangle. After transformation, the size reduced to give us ∆WXY. This means ∆TUV was reduced by a scale factor to give ∆WXY. The scale factor should be a fraction, suggesting, the original size of the ∆ was reduced upon transformation.

Thus, the ratio of their corresponding sides = the scale factor.

This is: $\frac{8}{12} = \frac{16}{24} = \frac{12}{18} = \frac{2}{3}$

If you multiply the side length of ∆TUV by ⅔, you'd get side length of ∆WXY.

So, Theodore is wrong.

There are 2,100 bacteria in a circular petri dish. The dish has a radius of 40 millimeters. What is the approximate population d

OleMash [197]

Answer: 0.42 bacteria/mm^2

Step-by-step explanation: Population density is population / area. First we solve for the area of the circle. A = pi•r^2. r = 40 mm. pi • 1600 = 5024mm^2. Divide the 2100 bacteria by 5024 and you get population density. 2,100/5024 = 0.42 (rounded to two decimal places)

What's the length of a segment that begins at the point (2, 3) and ends at the point (18, 15)?

DerKrebs [107]

So first of all we need to find the slope and it will give us the answer what is the length of a segment.

To find it we are using the formula:
y2-y1/x2-x1.

15-3/18-2=12/16=3/4.
So I think that the length of the segment is 3/4 cm or what you didn’t tell it for me. Hope this helps.

Which of the following is an equivalent expression for tan to the power of minus 1 end exponent x plus tan to the power of minus

tino4ka555 [31]

Answer:

c)

Step-by-step explanation:

To solve this, remember some properties of trigonometric functions.

Let $y=\tan^{-1} (x)$ . Then, by definition of inverse function, $\tan(y)=x$ . Multiply by -1 to both sides of this equation to get $-\tan(y)=-x$ .

Note that $-\tan(y)=\frac{-\sin(y)}{\cos(y)}=\frac{\sin(-y)}{\cos(y)}=\frac{\sin(-y)}{\cos(-y)}=\tan(-y)$ because sine is an odd function and cosine is an even function. Then $\tan(-y)=-x$ . Take the inverse tangent in both sides to get $-y=\tan^{-1} (-x)$ .

Using the previous equations, we obtain:

$\tan^{-1} (x)+\tan^{-1} (-x)=y+(-y)=0$
