you owe $2154.35 on your PBnJ credit card that has an interest rate of 9.85% APR, rather than placing $435 into a savings account earning 2.5% APR, you pay down the principal at the beginning of the month on the credit card. How much interest did you save? (HINT: Calculate the difference between the interest you would earn from the savings account and the interest you would pay on your credit card for the $435)
Answer:
if that $100 was on a loan or credit card, your debt could grow and grow until the interest you owe was more than the original principal! Credit Score or Rate. Your credit score is how well you pay off your credit .

Answer:
36 in^3
Step-by-step explanation:
1) find the area of the triangle
A = (leg 1 x leg2)/2 = (3 x 4)/2 = 6 in^2
2) find the volume
V = base area x height = 6 x 6 = 36 in^3

An object is spinning around a circle at a rate of 420 revolutions per minute. If the circle has a diameter of 8 feet, what is its angular speed in degrees per minute. Do not add the units into your answer.
Answer:
Step-by-step explanation:
This seems more like a physics questions, but i'll help you :P
the circle is 8 feet across or a radius of 4 feet
circumference of the circle is 2[tex]\pi[/tex]r = 25.132741 feet
it's going around 420 times a minute
420 * 25.132741 = 10555.75132 feet per minute

A store owner decided to collect data on his customers. On one day he observed:
48 people bought 1 item
32 people bought 2 or more items
16 people did not buy anything
Based on the data from that day, what is the probability that the next person to visit
the store will buy 2 or more items?
5
25
16
No links
Answer:
Step-by-step explanation:
Since a total of 96 people have entered the store and 32 of them have bought 2 or more items, it is clear that the next person entering the store has a probability of 32/96 or 1/3 that he/she will buy 2 or more items.

Step-by-step explanation:
During a flu epidemic, 35% of the school's students have the flu. Of those with the flu, 90% have high
temperatures. However, high temperatures are possible for people who do not have the flu. It is estimated that
12% of those without the flu have high temperatures.
If a student has a high temperature, what is the probability that the student has the flu?
Answer: 0.8015
Step-by-step explanation:
Let F= event that a person has flu
H= event that person has a high temperature.
As per given,
P(F) =0.35
Then P(F')= 1- 0.35= 0.65 [Total probability= 1]
P(H | F) = 0.90
P(H|F') = 0.12
By Bayes theorem, we have
[tex]P(F|H)=\dfrac{P(F)\timesP(H|F)}{P(F)\timesP(H|F)+P(F')\timesP(H|F')}\\\\=\dfrac{0.35\times0.90}{0.35\times0.90+0.65\times0.12}\\\\=\dfrac{0.315}{0.315+0.078}\approx0.8015[/tex]
Required probability = 0.8015

Naomi has a bag that contains pineapple chews, cherry chews, and peach chews. She performs an experiment. Naomi randomly removes a chew from the bag, records the result, and returns the chew to the bag. Naomi performs the experiment 72 times. The results are shown below: A pineapple chew was selected 31 times. A cherry chew was selected 3 times. A peach chew was selected 38 times. Based on these results, express the probability that the next chew Naomi removes from the bag will be pineapple chew as a decimal to the nearest hundredth.
Answer:
0.43
Step-by-step explanation:
Answer:
0.43

Givens
r = 1.5 inches
h = 4 inches
Formula
V = 1/3 pi r^2 h
V = 1/3 3.14 * 1.5^2 * 4
V = 1/3* 3.14 * 2.25 * 4
V = 9.42
Semi sphere
Givens
r = 1.5
Formula
V = 2/3 * pi * r^3
Solution
V = 2/3 * 3.14 * 1.^3
V = 7.065
Total
V = 9.42 + 7.065
V = 16.485
Rounded to the nearest 1/100
V = 16.49

Line m passes through the point (1, 2) and has a slope of 2/5 What is the equation of line m in standard form?
Answer:
5y - 2x = 8
Step-by-step explanation:
First off we have to find the y-intercept with : b = y-mx
[tex]b=2-(\frac{2}{5})(1)[/tex]
[tex]b=\frac{10}{5}-\frac{2}{5}[/tex]
[tex]b=\frac{8}{5}[/tex]
now we have the point slope form
[tex]y=\frac{2}{5}x+\frac{8}{5}[/tex]
Multiply both sides by 5
[tex]5y=2x+8[/tex]
Subtract 2x from both sides
[tex]5y-2x=8[/tex]

A state university annual report showed that its retention rate was at 24% and university administrators would like to increase this rate. After implementing several new programs during the last two years, the university reevaluated its retention rate. What is the correct alternative hypotheses for a test to determine whether the retention rate has increased during the last two years
Answer:
the alternative hypothesis is - p > 0.24
Step-by-step explanation:
Given that the retention rate is 24% = 0.24
So,
The alternative hypothesis is -
p > 0.24
Because the retention rate has increased during the last two years.
Factorise the following expression:
[tex] {a}^{2} + 10a + 24[/tex]
Step-by-step explanation:
[tex]a^{2} + 10a + 24[/tex]
= [tex]a^{2}[/tex] + 6a + 4a + 24
= a(a + 6) + 4(a + 6)
= (a + 6)(a + 4)
Answer:
solution:
[tex] {a}^{2} + 10a + 24[/tex]
a²+6a+4a+24
a(a+6)+4(a+6)
(a+6)(a+4) is your answer
