Answer:
Step-by-step explanation:
1,4 ,13 , __________, 121
First term = 1
Second term = 1 + 3 = 4
Third term = 4 + 3*3 = 4 + 9 = 13
Fourth term = 13 + 3*3*3 = 13 + 27 = 40
2) 5, 12 , 33 ,_____
First term = 5
Second term = 5 + 7 = 12
Third term = 12 + 7*3 = 12 + 21 = 33
Fourth term = 33 + 7*3*3 = 33 + 63 = 99

Step-by-step explanation:
Ronna answered 18 of the 20 questions on her second math test correctly. On the first test, she had answered only 15 of 20 questions correctly. What was the percent increase in her score from her first test to the second test? A. 15% B. 35% C. 75% D. 90
Answer:
A: 15%
Step-by-step explanation:
First test:
15 ÷ 20 = 0.75
0.75 * 100 = 75%
Second Test:
18 ÷ 20 = 0.9
0.9 * 100 = 90%
90% - 75% = 15%

Answer:
1) Yes, table shows a probability distribution
2) Mean = 1.5
3) Standard Deviation = 1.1
Step-by-step explanation:
PART 1:
For the table to show a probability distribution, the sum of all probabilities should be equal to 1
Sum of probabilities = 0.358 + 0.443 + 0.174 + 0.025
Sum of probabilities = 1
Hence, the table shows the probability distribution.
PART 2:
The formula for mean is given by:
Mean = Sum of terms/ Total no. of terms
Mean = (0+1+2+3) / 4
Mean = 1.5
PART 3:
The formula for standard deviation is given by:
[tex]\sigma=\sqrt{\frac{\sum(x_i-\mu)^2}{N}}[/tex]

Put the steps in the correct order to show how a budget is made.
First Step
T1 Total up spending
11 Reduce expenses in flexible categories to save or increase savings
Ti Calculate income
Ti Determine if spending is below income
11 Categorize expenses
Final Step
Answer:
The correct answer is: Calculate income, Total up spending, Categorize expenses, Determine if spending is below income, and Reduce expenses in flexible categories to save or increase savings. When making a budget, it's first necessary to figure out how much money comes in and goes out, and then to compare expenses to income to make cuts if necessary.

At 50, Brian sets up an IRA, where he plans to deposit $12,000 at the end of each year until age 75. Find the amount of the annuity if he invests in a stock fund that yields 4% compounded annually.
Answer: the amount of the annuity is $501000
Step-by-step explanation:
We would apply the future value which is expressed as
FV = C × [{(1 + r)^n - 1}/r]
Where
C represents the yearly payments.
FV represents the amount of money
in your account at the end of 25 years.
r represents the annual rate.
n represents number of years or period.
From the information given,
r = 4% = 4/100 = 0.04
C = $12000
n = 75 - 50 = 25
Therefore,
FV = 12000 × [{(1 + 0.04)^25 - 1}/0.04]
FV = 12000 × [{2.67 - 1}/0.04]
FV = 12000 × 41.75
FV = $501000
AB is included between
A. BC and AC
B.
C. < A and
D. AB and BC
Answer:
Option C.
Step-by-step explanation:
By the property of unique triangles (ASA), one side is included between the two angles.
By this property, if included side of the triangle ABC is AB then this side will be included between the two angles A and B.
Therefore, [tex]\bar{AB}[/tex] is included between ∠A and ∠B.
Option C. will be the answer.

Renee can see a 25 square foot quilt in 16 hours. Genera can sew the same size quilt in 12 hours. How long would it take them to see the quilt together?
28 hours because they are too long from each other
Answer:
Approximately 6.86 hours.
Step-by-step explanation:
Renee sews at a rate of 1.5625 sq ft an hour. Found using square feet divided by hours.
Genera sews at a rate of 2.084 sq ft an hour. Found using square feet divided by hours.
To find how fast they can sew the quilt together, we must add their sewing speeds together: 1.5626 + 2.084 = 3.64583333.
Using this equation we can divide a 25 sq ft quilt by their speed of 3.64583333 to get approximately 6.86 hours.
The answer is approximate because we used rounded decimals.
Find the value of n.
Answer:
n = -1.5
Step-by-step explanation:
[tex]\frac{1}{(\sqrt2)^{3} } } = 0.353553[/tex]
log ( [tex]2^{n}[/tex] ) = log (.353553)
n = [tex]\frac{log (0.353553) }{log (2)} = -1.5[/tex]

what is th rate equivalent to an annual rate of 20% with monthly capitalization
Answer:
about 21.9%
Step-by-step explanation:
The effective annual multiplier is ...
(1 +r/n)^n = (1 +0.20/12)^12 ≈ 1.21939
The rate equivalent is 1 less than this:
1.21939 -1 = 0.21939 = 21.939%

Nelson decides to invest $1,000,000 in a period annuity that earns 4.8% APR
compounded monthly for a period of 15 years. How many years will it take
Nelson to earn back his initial investment?
Answer:
21yearsStep-by-step explanation:
Amount invested by Nelson = $1,000,000
Interest rate per month = 4.8%
Simple Interest = Principal * Rate * Time/100
simple Interest = $1,000,000 * 4.8 *(1/12)/100
simple Interest = $1,000,000 * 4.8/1200
simple interest = $4,000/ month
Simple interest for one year = $4,000*12 = $48,000
In order to determine the number of years it will take Nelson to earn back his initial investment, we will divide its initial investment by the interest earned on the investment yearly as shown;
amount of years = $1,000,000/ $48,000
Amount of years = 20.8years ≈ 21years
10.7 years
Step-by-step explanation:

Which equation correctly represents the distance between - 15.1 and -3.9 on a number line?
- 3.9 - (-15.1)] = 11.2
-3.9 - 15.1 = -11.2
|- 15.2 + (-3.9) |= 19
-15.1 - 3.9 = -19
Answer:
Step-by-step explanation:
Keep in mind that distance is positive, not negative. Eliminate the negative results.
- 3.9 - (-15.1)] = 11.2 is correct. -(-15.1) - 3.9 is approximately 15 - 4, or 11, which agrees with the 11.2 correct result.
