serg [7]

Answer:

13.22

Step-by-step explanation:

were solving for t and we know:

a(t)=p(1+(r/n))^nt

5000=a-the total

2940=p-the starting amount

.041=r-the rate

1=n-compound (annual)

plug this into a graph :

5000=2940(1+(.041/1))^x

and you get : 13.22

A study was conducted to measure the effectiveness of hypnotism in reducing pain. The measurements are centimeters on a pain sca

blondinia [14]

The confidence interval for mean of the "before-after" differences is $\fbox{(-0.4037,1.8037)}$

Further explanation:

Find the difference between the before pain and the after pain.

Difference = before-after

Kindly refer to the Table for the difference of between the before and after pain.

Sum of difference = $5.6$

Total number of observation = $8$

Mean of difference = $0.7$

Sample standard deviation $s$ = $1.3201$

Level of significance = $5\%$

Formula for confidence interval = $\left( \bar{X} \pm t_{n-1, \frac{\alpha}{2}\%} \frac{s}{\sqrt{n}} \right)$

confidence interval = $\left( 0.7 \pm t_{8-1, \frac{5}{2}\%} \frac{1.3201}{\sqrt{8}} \right)$

confidence interval = $\left( 0.7 \pm t_{7, \frac{5}{2}\%} \frac{1.3201}{\sqrt{8}} \right)$

From the t-table.

The value of $t_{7, \frac{5}{2}\%$ = $2.365$

Confidence interval = $( 0.7 \pm 2.365}\times \frac{1.3201}{\sqrt{8}}) \right)$

Confidence interval = $\left( 0.7 - 2.365}\times \0.4667,0.7 + 2.365}\times \0.4667) \right$

Confidence interval = $(0.7-1.1037,0.7+1.1037)$

Confidence interval = $\fbox{(-0.4037,1.8037)}$

The $95\%$ confidence interval tells us about that $95\%$ chances of the true mean or population mean lies in the interval.

Yes, the hypnotism appear to be effective in reducing pain as confidence interval include includes the positive deviation from the mean.

The hexadecimal number is 0xFEE. what will be the octal number of this?

Vikentia [17]

Answer:

0xFEE₁₆ = 7756₈

Step-by-step explanation:

Convert the hexadecimal number to decimal first

0xFEE

E = 14

F = 15

Then convert them to binary

$\frac{14}{2}=7$

Remainder = 0

$\frac{7}{2}=3$

Remainder = 1

$\frac{3}{2}=1$

Quotient = 1

Remainder = 1

$\frac{15}{2}=7$

Remainder = 1

$\frac{7}{2}=3$

Remainder = 1

$\frac{3}{2}=1$

Quotient = 1

Remainder = 1

0 F E E

0000 1111 1110 1110

Take groups of three

and multiply with $2^n$ where n is the place of the digit

111 111 101 110

4,2,1 4,2,1 4,2,1 4,2,1

4+2+1 4+2+1 4+0+1 4+2+0

7756

So, 0xFEE₁₆ = 7756₈
