Find the amount of interest to be paid.
Principal: $780
Annual Rate of Interest: 12 1/2%
Time: 6 months
Use the formula: i = prt (principal, rate, time)
Answer:
P = 780
R = 12 1/2%
T = 6
780 x 12 1/2% x 6 = $2808.005

PLEASE HELP ME WITH THIS ALGEBRA QUESTION!! THANK YOU!!
Answer:
The first four terms of the sequence are: {-10,-23,-62,-179}
Step-by-step explanation:
Given recursive formula is:
[tex]a_n = 3a_{n-1}+7[/tex]
First term = a1 = -10
The first term is already known. In order to find the next terms, we will put n=2,3,4 in the recursive formula.
Putting n=2
[tex]a_2 = 3a_{2-1}+7\\a_2 = 3a_1+7\\a_2 = 3(-10)+7\\a_2 = -30+7\\a_2 = -23[/tex]
Putting n=3
[tex]a_3 = 3a_{3-1}+7\\a_3 = 3a_2+7\\a_3 = 3(-23)+7\\a_3 = -69+7\\a_3 = -62[/tex]
Putting n=4
[tex]a_4 = 3a_{4-1}+7\\a_4 = 3a_3+7\\a_4 = 3(-62)+7\\a_4 = -186+7\\a_4 = -179[/tex]
Hence,
The first four terms of the sequence are: {-10,-23,-62,-179}
A store had 50 bottles of olive oil. Each week, 40% of the olive oil bottles were sold and 20 new bottles arrived in shipments. Which recursive function best represents the number of bottles in the store, given that f(0) = 50?
Answer:
f(n) = f(n-1)*.6 + 20
Step-by-step explanation:
f(0) = 50
f(n) = f(n-1)*.6 + 20
In fact, since f(0) = 50, f(n) = 50.
A researcher claims that the variation in the salaries of elementary school teachers is greater than the variation in the salaries of secondary school teachers (the claim). A random sample of 30 elementary school teachers has a variance of $ 8324, and a random sample of 30 secondary school teachers has a variance of $2862. At α= 0.05, can the researcher conclude that the variation in the elementary school teachers' Salaries is greater than the variation in the secondary teachers' salaries? Use the P-value method.
Assume that all variables are normally distributed.
a. State the hypotheses and identify the claim.
b. Find the critical value.
c. Compute the test value.
d. Make the decision.
e. Summarize the results.
Answer:
a
The null hypothesis is [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]
The alternative hypothesis is [tex]H_a : \sigma_1 ^2 > \sigma^2_2[/tex]
b
[tex]F_{critical} = 1.8608[/tex]
c
[tex]F = 2.9085[/tex]
d
The decision rule is
Reject the null hypothesis
e
There is sufficient evidence to support the researchers claim
Step-by-step explanation:
From the question we are told that
The first sample size is [tex]n_1 = 30[/tex]
The sample variance for elementary school is [tex]s^2_1 = 8324[/tex]
The second sample size is [tex]n_2 = 30[/tex]
The sample variance for the secondary school is [tex]s^2_2 = 2862[/tex]
The significance level is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]
The alternative hypothesis is [tex]H_a : \sigma_1 ^2 > \sigma^2_2[/tex]
Generally from the F statistics table the critical value of [tex]\alpha = 0.05[/tex] at first and second degree of freedom [tex]df_1 = n_1 - 1 = 30 - 1 = 29[/tex] and [tex]df_2 = n_2 - 1 = 30 - 1 = 29[/tex] is
[tex]F_{critical} = 1.8608[/tex]
Generally the test statistics is mathematically represented as
[tex]F = \frac{s_1^2 }{s_2^2}[/tex]
=> [tex]F = \frac{8324 }{2862}[/tex]
=> [tex]F = 2.9085[/tex]
Generally from the value obtained we see that [tex]F > F_{critical }[/tex] Hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to support the researchers claim

20
Step-by-step explanation:There are two ways to solve this (both will end up with the same answer):
1st way:
You can find 4/9 of 36 to find how many displays the class explored so far. You can write it as 4/9 x 36, which is equal to 16. So, the class explored 16 displays so far. All you need to do is subtract 16 from 36 to find how many displays the class needs to explore, which can be written as 36-16, and is equal to 20.
Final answer: 20
2nd way:
You can do 1 minus 4/9 to find the left over fraction of the displays that the class needs to explore, which is equal to 5/9. Then, you need to find 5/9 of 36 to find how many displays are left for the class to explore. You can write it as 5/9 x 36, which is equal to 20.
Final answer: 20
Hope you understand and that this helps with your question :)

a vase costs $2 bridget has some money if she gets $4.45 more she can buy 5 vases how much money does she have
Answer:
Bridget has $5.55.
Step-by-step explanation:
First let's find how much money Bridget needs to buy 5 vases. To do this, multiply the cost per vase by the amount of vases she wants to buy:
2 * 5 = 10
It would cost $10 to buy 5 vases.
Bridget needs $4.45 in order to buy 5 vases. So, to find how much money she already has, subtract the amount of money she needs from the total cost of the 5 vases:
10 - 4.45 = 5.55
Bridget has $5.55.
Answer:
$ 5.55
Step-by-step explanation:
Find the price of 5 vases
Cost of 5 vases = 5 * 2 = $ 10
She needs $4.45 to buy 5 vases. If we subtract this 4.45 from $10, the result will be the money she has already with her
Money Bridget has = 10 - 4.45
= $ 5.55
Part A and Part B for Max's car together cost $1,693 dollars, Part A cost $58 dollars
more than twice what Part B cost. How much did each part cost?
Answer:
Part A: 1148
Part B: 545
Step-by-step explanation:
Part A: 2x + 58
Part B: x
2x + 58 + x = 1693
3x + 58 = 1693
3x = 1635
x = 545
Part A: 2x + 58 = 2(545) + 58 = 1148
Part B: x = 545

What is the probability that a randomly selected camper likes swimming or having a cookout, but not both?
A.
B.
C.
D
The probability that a randomly selected camper likes to have a cookout or swimming, but not both, is 0.10.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
The Venn diagram displays the campers’ preferences.
One circle is labeled S, 0.06,
the other circle is labeled C, 0.04,
the shared area is labeled 0.89,
and the outside area is labeled 0.01.
The probability that a randomly selected camper likes to have a cookout or swimming, but not both,
= 0.06 + 0.04
= 0.10
Therefore, 0.10 is the required probability.
