Answer:
It will take 10 months to pay off the unpaid balance.
Step-by-step explanation:
Given that the annual interest rate on a credit card is 15.30%, if a payment of $ 300.00 is made each month, to determine how many months will it take to pay off an unpaid balance of $ 2,590.67, the following calculation must be performed:
(2,590.67 x 1.1530) / 300 = X
2,987.04 / 300 = X
9.95 = X
Therefore, it will take 10 months to pay off the unpaid balance.

A density curve for all the possible weights between 0 pounds and 10 pounds is in the shape of a rectangle. What is the height of the rectangle in this density curve? O A. 0.01 OB. 0.001 O c. 0.1 O D. 0.0001 SUBMIT
Answer:
0.1
Step-by-step explanation:
For a density curve, total area = 1
Probability lies in between 0 and 1
The Area of rectangle :
Area = Length * width
Length = 0 - 10 = 10
Area = 1
Hence,
Area = Length * width
1 = 10 * w
1 = 10w
w = 1 /10
w = 0.1

The average age of 6 men is 35 years and
the average age of four of them is 32 years.
Find the ages of the remaining two men if
one is 3 years older than the other.
Answer:
39.50
42.50
Step-by-step explanation:
Age of the 2 men = sum of the ages of the 6 men - sum of the ages of the 4 men
Average = sum of ages / total number of men
35 = sum of ages / 6
sum of ages = 35 x6 = 210
32 = sum of ages / 4
32 x 4 = sum of ages
128
210 - 128 = 82
age of the younger man = x
age of the older man = 3 + x
x + 3 + x = 82
2x + 3 = 82
2x = 82 - 3
2x = 79
x = 79/2 = 39.5
older man = 39.5 + 3 = 42.50
Find the equation of the quadratic function determined from the graph above.
Nonsense = Report
Find the equation of the quadratic function determined from the graph above.
Solution:-The vertex of the graph of the quadratic function is (2, -3). The graph passes through the point (5, 0). By replacing x and y with 5 and 0, respectively, and h and k with 2 and -3, respectively we have,
[tex]\sf\rightarrow{y=a(x-h)²+k}[/tex]
[tex]\sf\rightarrow{O=a(5-2)²-3}[/tex]
[tex]\sf\rightarrow{0=a(3)²-3}[/tex]
[tex]\sf\rightarrow{3=9a}[/tex]
[tex]\sf\rightarrow{a=\frac{1}{3}}[/tex]
Answer:-Thus, the quadratic equation is...[tex]\sf\rightarrow{y=\frac{1}{3}(x-2)²-3}[/tex]
or,
[tex]\sf{y=\frac{1}{3} \: x²-\frac{4}{3} \: x-\frac{5}{3}}[/tex]
=====================#Hope it helps!

Answer:
y = (x-2)²/3 - 3
Step-by-step explanation:
the vertex is at (2,-3), so the vertex form of the function is
y = A(x-2)²-3
where A is a constant to be found.
We see that when x=5, y=0, so substitute values to find A.
0 = A(5-2)² - 3
solve for A to get
A(3²) = 3
A = 1/3
So the equation is
y = (x-2)²/3 - 3
Check for x = -1
y = (-1-2)²/3 - 3 = 0 checks

2. Simplify (2/3)^3 .
Answer:
8/27.
Step-by-step explanation:
Given expression: [tex](2/3)^3[/tex]
To correctly simplify this expression, you must first understand the role of exponents and base numbers.
The base number is the number being multiplied.
The exponent tells the base number how many times it should be multiplied by itself.
In this case, 2/3 is the base number and 3 is the exponent.
Exponential notations will always be written like this: [tex]x^n[/tex]
[tex]x-base[/tex]
[tex]n-exponent[/tex]
Now that we know the roles of the exponent and base number, we can correctly simplify this expression.
[tex](2/3)^3[/tex]
[tex]=2/3*2/3*2/3[/tex]
[tex]=8/27[/tex]
[tex]\to \ (2/3)^3=8/27[/tex]
Therefore, the value of [tex](2/3)^3[/tex] is 8/27.

Chisquare test
t - test
Correlation
ANOVA, F ratio.
Step-by-step explanation:
The Chisquare test is suitable for testing categorical variables with factors levels more than 3.
The t test of independence is suitable for testing continous variable, however re we use the two independent sample t test.
Correlation test is used to examine the relationship between two continous variable, cannot be used for categorical variables.
Analysis of Variance is use to test categorical variables with at lead three factor levels. The F ratio allows measurement and establishing of statistical significance exists between variables.

PLEASE HELP !!!!! ASAP PLEASE !!!! IM BEGGING LOL !!!!
Step-by-step explanation:
Hey there!
From the given figure;
Angle ABE = 90°.
And angle ABC= [(3x+7)° + (5x+11)°].
Now, Angle ABE + Angle ABC= 180° [Being linear pair].
or, 90° + (3x+7)° + (5x+11)°= 180°
or, (3x+7)° + (5x+11)°= 90°
or, 8x + 18° =90°
or, 8x = 90°-18°
or, X = 9°
Therefore, X= 9°.
Now,
Angle DBC = (5*9+11)°
= 56°
Therefore, the measure of angle DBC is 56°.

Find the weighted mean
Answer:
10.1
Step-by-step explanation:
weighted mean = sum of the multiplication of frequency and value /sum of frequency
sum of frequency = 5 + 5 + 5 + 21 = 36
sum of the multiplication of frequency and value = (16 x 5) + (20 x 5) + (16 x 5) + ( 5 x 21) = 365
365/36 = 10.1

The sound level of a jet plane is approximately 140 dB. The intensity of the sound of a jet plane is approximately
.
Answer:
280 DB
Step-by-step explanation:
If the sound level of a jet plane is approximately 140 dB, the intensity of the sound of a jet plane is approximately 100dB
What is sound level?Sound level is the intensity to measure the sound. Decibels are used to quantify sound levels.
The sound level of a jet plane is expressed according to the expression given:
β = 10log(I/I0)
Given the following parameters
β = 140dB
I0 = 10^-12 W/m²
For required Intensity "I" Substitute:-
140 =10log(I/10^-12)
14 = log(I/10^-12)
10^14 = I/10^-12
I = 10^14 * 10^-12
I = 10^2
I = 100dB
Hence if the sound level of a jet plane is approximately 140 dB, the intensity of the sound of a jet plane is approximately 100dB
