20%

A change from 65 to 78 represents a positive change (increase) of 20%

Use the formula found below to find the percent change by replacing the given values:

Percent change = [(New - Old ) / |Old|] x 100%

Based on the amount that Nader can pay per month, and the interest rate as well as the period, the amount he could spend if the rate was annual is $8,385.33.

<h3 /><h3>How much could Nader spend on the car?</h3>

If Nader can pay $280 per month, the amount he can pay per year i:

= 280 x 12

= $3,360

The amount that he can spend on the car is the present value of these yearly payments:

= 3,360 x (1 - (1 + 9.8%)⁻³) / 9.8%

= 3,360 x 2.49563439768461

= $8,385.33

A man buys a racehorse for $20,000 and enters it in two races. He plans to sell the horse afterward, hoping to make a profit. If
victus00 [196]

Answer:

The expected profit is $10,600.

Step-by-step explanation:

The expected profit can be calculated as the sum of the possible outcomes weighted by their probability of occurrence.

In this case, there are four possible outcomes:

1) The horse win both races. The value of the horse will be $100k-$20k=$80k.

The probability of this outcome is:

P(ww)=P(w1)*P(w2)=0.2*0.3=0.06

2) The horse win the first race, but lose the second one. The value will be $50k-$20k=$30k.

The probability is:

P(wl)=P(w1)*(1-P(w2))=0.2*(1-0.3)=0.2*0.7=0.14

3) The horse lose the first race, but win the second one. The value will be $50k-$20k=$30k.

The probability is:

P(lw)=(1-P(w1))*P(w2)=(1-0.2)*0.3=0.8*0.3=0.24

4) The horse lose both races. The value will be $10k-$20k=-$10k.

The probability is:

P(lw)=(1-P(w1))*(1-P(w2))=(1-0.2)*(1-0.3)=0.8*0.7=0.56

Then, the expected profit can be calculated as:

E(x)=\sum\limits^4_{i=1} {p_ix_i}\\\\E(x)=0.06*80,000+0.14*30,000+0.24*30,000+0.56*(-10,000)\\\\E(x)=4,800+4.200+7,200-5,600=10,600

What is the five-number summary for this data set?
Free_Kalibri [48]

Answer:

C

Step-by-step explanation:

min and max are correctly the same for all 4 answers.

we have 10 data points, so, the median is the mean value between the 2 middle numbers, 19 and 22 : 20.5.

ah, it can be only C or D.

Q1 is the median of the lower half of data points (13 out of 11, 12, 13, 17, 19). and Q3 is the median of the upper half of data points (29 out of 22, 24, 29, 33, 38).

so, C is correct.

The price of milk increased from $3.25 to $3.75. What is the percent of change for the price of milk to the nearest tenth? Show
nikitadnepr [17]
Percent = part/whole

It wants you to find the % of change so it's 3.25 / 3.75
And that comes out to be 0.86 (with the 6 repeating)
So you move the decimal over 2 places to find the percent.
And then it's 1 - Ans

The answer is 13.33%
