Answer:

Answer is 43.309.

Explanation:

First we have to find the mean to evaluate standard deviation. Hence,

$97, $102, $56, $26, $3/5

=56.8

Now find standard deviation using the attached formula,

Squareroot,Summation(97-56.8)^2+(102-56.8)^2+(56-56.8)^2+(26-56.8)^2+(3-56.8)^2/4

Squareroot1616.04+2043.04+0.64+948.64+2894.44/4

Squareroot1875.7

=43.309.

Answer:

Standard deviation= $43.309

Explanation:

Standard deviation can be defined as a measure of dispersion of a set of values from their mean. When standard deviation is low it means the variables are close to their mean. While if standard deviation is high the variables are far away from the mean.

The mean= (sum of the values)/number of values

Mean= (97+102+56+26+3)/5

Mean= $56.80

Standard deviation= √(Σ(x- mean)^2/number-1

Standard deviation= √{(97-56.8)^2+ (102-56.8)^2+ (56-56.8)^2+ (26-56.8)^2+ (3-56.8)^2}/5

Standard deviation= √(1616.04+2043.04+0.64+948.64+2894.44)/5-1

Standard deviation= √7502.8/4

Standard deviation= $43.309

Based on the weight of the consumer price index (CPI), the price of rental housing increases by 15% and that of owned housing by
Levart [38]

Answer:

D) all other factors being constant, it is likely the CPI would rise during the year in question.

Explanation:

The CPI measures the price of a basket of goods and that basket includes both housing expenses and gasoline, but housing expenses are "heavier" than gasoline (their relative weight on the CPI is much higher) because they represent a much larger portion of a household's income. It is common for a family to pay $1,000 (or much more) per month on rent or a mortgage, while how many people actually spend over $1,000 per month on gas?

melomori [17]

Answer:

Tumusiime Stationers

a) Journal Entries on 14/10/2020:

Debit Office Suppliers Sh 60,000

Credit Cash Account Sh 59,400

Credit Purchase Discount Sh 600

To record the payment in full on account.

Office Suppliers

b) Journal Entries on 14/10/2020:

Debit Cash Account Sh 59,400

Debit Sales Discount Sh 600

Credit Tumusiime Stationers Sh 60,000

Explanation:

Other Journal entries made by Tumusiime and Office Suppliers are:

Tumusiime:

October 4, 2020:

Debit Inventory Sh 62,000

Credit Office Suppliers Sh 62,000

To record the purchase of goods on account,  terms of 1/10, n/30.

Debit Office Suppliers Sh 2,000

Credit Inventory  Sh 2,000

To record the return of goods on account.

Office Suppliers:

October 4, 2020:

Debit Tumusiime Stationers $62,000

Credit Sales Revenue $62,000

To record the sale of goods on account,  terms of 1/10, n/30.

Debit Sales Returns $2,000

Credit Tumusiime Stationers $2,000

To record the return of goods on account.

b) Calculations:

To determine the amount of returns, we first calculate the balance before the discount.  Since the discount equals 1%, it implies that Sh 59,400 = 99% (100 - 1%).  Therefore, 100% of Sh 59,400 = Sh 60,000 (59,400/99%).  This shows that Sh 2,000 (Sh 62,000 - 60,000) was the amount of returns made.
