Answer: -2/5

Step-by-step explanation: It's -4/5 multiplied by 1/2 because you you have to find the reciprocal, so you flip 2, so it would become 1/2, then you multiply -4/5 and 1/2, which would get you -4/10, which can be reduced to -2/5. Hope this helps!

Answer:

A) An 80% confidence interval for the population mean score of the current group of applicants is (172.8124,202.9876)

B)The confidence level of this interval is 96%

Step-by-step explanation:

Mean =[tex]\mu = 187.9[/tex]

Standard deviation = s= 32.4

n = 9

A) Find an 80% confidence interval for the population mean score of the current group of applicants.

Degree of freedom = n-1=9-1=8

Significance level = [tex]\alpha = 0.2[/tex]

So, [tex]t_(\frac{\alpha}{2},df)=t_(\frac{0.2}{2},8)=t_(0.1,8)=1.397[/tex]

Formula of confidence interval :

CI : [tex]\bar{x}-Z_{(\frac{\alpha}{2})} \times \frac{s}{\sqrt{n}} , \bar{x}+Z_{(\frac{\alpha}{2})}\times \frac{s}{\sqrt{n}}[/tex]

So, CI:  [tex]187.9-1.397 \times \frac{32.4}{\sqrt{9}} , 187.9+1.397 \times \frac{32.4}{\sqrt{9}}[/tex]

CI:(172.8124,202.9876)

So, an 80% confidence interval for the population mean score of the current group of applicants is (172.8124,202.9876)

B)Based on these sample results, a statistician found for the population mean a confidence interval extending from 165.8 to 210.0 points. Find the confidence level of this interval.

Standard error of sample mean = se =[tex]\frac{s}{\sqrt{n}}= \frac{32.4}{\sqrt{9}} = 10.8[/tex]

Margin of error = 210 - 165.8 = 44.2

Critical test statistic =[tex]\frac{\text{margin of error}}{2 \times \text{standard error}} = \frac{44.2}{2 \times 10.8} = 2.0463[/tex]

Using excel

Confidence interval = [tex]2 \times [1 - NORMSDIST(2.0463)] = 2 \times (1 - 0.98) = 2 \times 0.02 = 0.04[/tex]

Confidence level= 1 - 0.04 = 0.96

Confidence interval is 96%.

Hence  the confidence level of this interval is 96%

Using the z-distribution, it is found that

a) The 80% confidence interval for the population mean score of the current group of applicants is (174.1, 201.7).

b) The confidence level is of approximately 96%.

Item a:

We are given the standard deviation for the population, which is why the z-distribution is used to solve this question.

The information given is:

The confidence interval is:

[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]

The critical value, using a z-distribution calculator, for a two-tailed 80% confidence interval is z = 1.28.

[tex]\overline{x} - z\frac{\sigma}{\sqrt{n}} = 187.9 - 1.28\frac{32.4}{\sqrt{9}} = 174.1[/tex]

[tex]\overline{x} + z\frac{\sigma}{\sqrt{n}} = 187.9 + 1.28\frac{32.4}{\sqrt{9}} = 201.7[/tex]

The 80% confidence interval for the population mean score of the current group of applicants is (174.1, 201.7).

Item b:

The margin of error is given by:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

Hence:

[tex]\frac{210 - 165.8}{2} = z\frac{32.4}{\sqrt{9}}[/tex]

[tex]10.8z = 22.1[/tex]

[tex]z = \frac{22.1}{10.8}[/tex]

[tex]z = 2.05[/tex]

Using a calculator, it is found that the confidence level is of approximately 96%.

Answer:

2.1 mpm

Explanation:

1ft = 0.3048 m

[tex]0.3048*7=2.1336[/tex]

The given speed in meters per second is 0.00356 m/sec.

Given that, an object is moving at a speed of 7 feet per minute.

We need to express this speed in meters per second.

Feet per minutes. In SI units [tex]5.08 \times 10^{-3}[/tex] meters per second.

Meters per second is the base unit for measuring velocity or speed in the International System of Units (SI). Speed is a measure of distance travelled over time, velocity is speed in a given direction. 1 meter travelled over a period of 1 second = 1 m/s.

For an approximate result, divide the speed value by 1969.

Now, 7/1969=0.003555

≈0.00356

Therefore, the given speed in meters per second is 0.00356 m/sec.

Answer:

15/18 pages per minute

Step-by-step explanation:

[tex]7 \frac{1}{2} = \frac{7 \times 2 + 1}{2} = \frac{14 + 1}{2} = \frac{15}{2} \\ \\ average \: reading \: rate \\ = \frac{ \frac{15}{2} }{9} \\ \\ = \frac{15}{2 \times 9} \\ \\ = \frac{15}{18} \: pages \: per \: minute[/tex]

You divide the opposite over the hypotenuse

sin(angle) = opposite/hypotenuse

With respect to reference angle P, the opposite side is QR = 5 since it is the leg furthest from the angle P.

The hypotenuse is always the longest side and always opposite the 90 degree angle (the largest angle of any right triangle).

Step-by-step explanation:

Sorry if wrong.

5) x = 8

6) z = 49°

Hi there !

5)

we have opposite angles =>

5x = 2x + 24

5x - 2x = 24

3x = 24

x = 24 : 3

x = 8

6)

The sum of the three interior angles in a triangle is always 180° !

x = 180° - (28° + 39°)

= 180° - 67°

= 113°

x ; y = supplementary angles =>

x + y = 180° =>

y = 180° - x

= 180° - 113°

= 67°

z = 180° - (64° + 67°)

= 180° - 131°

= 49°
