Andrews [41]

Step-by-step explanation:

To determine simple interest, we use the formula

$I=Prt$

where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years

When the times is 3 years , then we plug in 3 for 't' directly

$I=Pr(3)\\$

we know that 1 year = 12 months

Suppose, the time is given in months then we divide time 't' by 12

When the times is 4 months , then we plug in 4 for 't' and divide by 12

$I=\frac{Pr(4)}{12}$

we know that 1 year = 365 days

Suppose, the time is given in days then we divide time 't' by 365

When the times is 45 days , then we plug in 45 for 't' and divide by 365

$I=\frac{Pr(45)}{365}$

Judy buys dorito bags $0.40 each and sold them for $1.00 each. what was the percent increase

myrzilka [38]

Getting the percentage increase, we can form the formula or equation.
Percentage increase = ($1.00 - $0.40) / $0.40 * 100
Percentage increase = ($0.60) / $0.40 * 100
Percentage increase = 1.5 * 100
Percentage increase = 150%

So there is a 150% increase from the original price.

Renauld has to pay 2 percent in closing costs and 14 percent for the down payment on a purchase of $170,500. Over the life of hi

melamori03 [73]

Renaud has to pay 2 percent + 14 percent = 16 percent initial costs

We can establish a proportion:

If 100% is => $170,500

Then 16% => $C costs

$C = 16 x $170,500/100 = $27,280 initial costs

Total cost = $163,021.87 + $27,280 = $190,301.87

Answer : C.) $190,301.87

Find the IQR (interquartile range). 19, 21, 18, 17, 18, 22,46

yanalaym [24]

Answer:

4.

Step-by-step explanation:

Step 1: Formula.

$IQR=Q3-Q1$

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 2: Explain/define.

The interquartile range is the difference between quartile 3 and quartile 1.
Quartile 1 is the median of the upper half of a data set.
Quartile 3 is the median of the lower half of a data set.
The median is the 'middle value.'

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 3: Order/arrange.

In order to find the median, you must first put the numbers in numerical order.

19, 21, 18, 17, 18, 22, 46

↓

17, 18, 18, 19, 21, 22, 46

The lower half of the data set, not including the median of the whole data set, is 17, 18, and 18.

The upper half of the data set is 21, 22, and 46.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 4: Solve.

17, 18, 18

21, 22, 36

Next, we find the medians of both sets.

The median of the lower half is 18 (Q1).

The median of the upper half is 22 (Q3).

Lastly, we subtract Q3 from Q1.

$22-18=4.$

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 5: Conclude.

I, therefore, believe the interquartile range of this data set is 4.
