Plzz show workings while giving the answer

Answer:

$\huge\boxed{\sf 4\ minutes\ 1.5\ seconds}$

Step-by-step explanation:

3 minutes 59.1 seconds = (3*60) + 59.1 seconds = 180 + 59.1 seconds

=> 239.1 seconds

$\rule[225]{225}{2}$

4 minutes 3.8 seconds = (4*60) + 3.8 seconds = 240 + 3.8 seconds

=> 243.8 seconds

$\rule[225]{225}{2}$

4 minutes 1.6 seconds = (4*60) + 1.6 seconds = 240 + 1.6 seconds

=> 241.6 seconds

$\rule[225]{225}{2}$

Mean = Sum of data / No. of Data

Mean = 239.1 + 243.8 + 241.6 / 3

Mean = 724.5 / 3

Mean = 241.5 seconds

<u>In Minutes and Seconds:</u>

= 241.5 / 60 = 4.025 minutes

= 4 minutes + 0.025 minutes

= 4 minutes + (0.025 * 60) seconds

= 4 minutes 1.5 seconds

$\rule[225]{225}{2}$

Hope this helped!

1. In an arithmetic sequence, if a4 = 18 and a10 = 30, determine a1, d, and an.

GalinKa [24]

<span>In an arithmetic sequence, if a4 = 18 and a10 = 30, determine a1, d, and an.

Then write the first four terms of the sequence.

Use the formula L = A + (N-1)D, where L represents the nth term.

Then, based upon the given info,

18 = A + (4-1)D and 30 = A + (10-1)D.
The first equation boils down to 18 = A + 3D, so that A = 18 - 3D. Subst. 18-3D for A in the second equation: 30 = 18-3D + 9D. Then 12=6D and D = 2.
</span><span>
Use </span>A = 18 - 3D to determine the value of A. Recall that D=2.

Then A = 18 - 3(2), or A = 18-6, or A = 12.

Then L = A + (N-1)D becomes L = 12 + (N-1)(2).

First term is 12. Next is 14; next is 16; last is 18.

According to a study of political prisoners, the mean duration of imprisonment for prisoners with chronic post-traumatic stres

Ray Of Light [21]

This question is incomplete, the complete question is;

According to a study of political prisoners, the mean duration of imprisonment for 33 prisoners with chronic post-traumatic stress disorder (PTSD) was 34.2 months. Assuming that σ = 40 months.

determine a 95% confidence interval for the mean duration of imprisonment, μ , of all political prisoners with chronic PTSD. Interpret your answer in words.

Answer:

⇒ ( 20.6, 47.8 )

Therefore, 95% confidence interval for the mean duration of imprisonment μ of all political prisoners with PTSD is between 20.6 months and 47.8 months.

Step-by-step explanation:

Given the data in the question;

sample size; n = 33

standard deviation σ = 40 months

x' = 34.2 months

Now, at 95% confidence interval;

we know that z-value of 95% confidence interval is 1.96

so we substitute into the formula below;

⇒ x' ± Z( σ/√n )

⇒ 34.2 ± 1.96( 40/√33 )

⇒ 34.2 ± 13.647

we have

( 34.2 - 13.647 ), ( 34.2 + 13.647 )

⇒ ( 20.6, 47.8 )

Therefore, 95% confidence interval for the mean duration of imprisonment μ of all political prisoners with PTSD is between 20.6 months and 47.8 months.
