vladimir2022 [97]

Answer:

Step-by-step explanation:

a). Mean of the given data set = $\frac{32+28+18+40+22}{5}$

= 28

b). x $x-\overline{x}$ $(x-\overline{x})^2$

32 32-28 = 4 16

28 28 - 28 = 0 0

18 18 - 28 = -10 100

40 40 - 28 = 12 144

22 22 - 28 = -6 36

$\sum({x-\overline x})^2$ = 296

c). Standard deviation = $\sqrt{\frac{\sum (x-\overline{x})^2}{n}}$

= $\sqrt{\frac{296}{5} }$

= 7.69

d). Mean of the new set of weights = $\frac{32+33+34+35+36}{5}$

= 34

Since mean of the data set is more close to each data, standard deviation will be less than the deviation given in part (c).

Encik Zulhazim deposited RM8000 in a fixed deposit account at Bank T for 2 years with interest rate of 5% per annum. What is the

creativ13 [48]

Answer: $34.08

Step-by-step explanation:

$\text{Compound Interest}:A=P\bigg(1+\dfrac{r}{n}\bigg)^{nt}\\\\\bullet A=\text{accrued amount (final balance)}\\\bullet P=\text{principal (amount invested)}\\\bullet r=\text{interest rate (convert percentage to a decimal)}\\\bullet n=\text{number of times compounded (in one year)}\\\bullet t=\text{time (number of years)}\\\\\\\underline{\text{Given:}}\\\bullet P=8000\\\bullet r=5\% (0.05)\\\bullet n=3\ \text{(every 4 months is 3 times per year)}\\\bullet t=2$

$A=8000\bigg(1+\dfrac{0.05}{3}\bigg)^{3(2)}\\\\\\A = \large\boxed{8834.08}$

$\text{Simple Interest}:A=P(1+rt)\\\\A=8000+8000[1+0.05(2)]\\\\A=\large\boxed{8800.00}$

Difference = Compound Interest - Simple Interest

= 8834.08 - 8800.00

= 34.08

two buses leave Houston at the same time and travel in opposite directions. one bus averages 55 mi/h and the other bus averages

Alenkasestr [34]

4 hours after they leave Houston. Easiest way to solve this problem is to first calculate the relative velocities of the two buses. Since they're traveling in opposite directions, you simply need to add their respective velocities to see what the relative velocity is between them. 55 mi/h + 45 mi/h = 100 mi/h That means that the buses will increase their distance apart from each other by 100 miles for every hour that they travel. So divide 400 miles by 100 miles/hour 400 miles / 100 miles/hour = 4 hours. So 4 hours after the buses start moving, they will be 400 miles apart from each other.

Can someone help me?

Daniel [21]

SOLUTION:

BF = MIDPOINT

MIDPOINT means the half-way point.

Therefore:

CE = 90

BF = CE / 2

BF = 90 / 2

BF = 45

Hope this helps! :)
Have a lovely day! <3
