Jada recently graduated from college with $34,000 in federal student loans at a fixed 3. 73% annual interest rate, compounded monthly. She makes a monthly payment of $340 with the goal of paying her loans off in ten years. What is the monthly interest rate on Jada's student loans? Round to the nearest thousandth of a percent
The monthly interest rate on Jada's student loans is 0.308%.
To find the monthly interest rate, we convert the annual interest rate of 3.73% to a monthly rate using the formula (1 + Annual Interest Rate)^(1/12) - 1.
Plugging in the values, we get (1 + 0.0373)^(1/12) - 1, which simplifies to approximately 0.003083, or 0.3083% when rounded to the nearest thousandth of a percent.
To calculate the monthly interest rate on Jada's student loans, we first need to convert the annual interest rate to a monthly rate.
The formula to convert an annual interest rate to a monthly rate is:
Monthly Interest Rate = (1 + Annual Interest Rate)^(1/12) - 1
In this case, the annual interest rate is 3.73%. Let's calculate the monthly interest rate:
Monthly Interest Rate = (1 + 0.0373)^(1/12) - 1
Using a calculator, we can find that the monthly interest rate is approximately 0.003083, or 0.3083%.
Rounding to the nearest thousandth of a percent, the monthly interest rate on Jada's student loans is 0.308%.

ABCD is a trapizoid of bases [AB] and [DC], M and N are the midpoint of [AD] and [BC] if DC=11cm and MN=9cm then AB=
Answer:
\(AB = 7\)
Step-by-step explanation:
Given
\(DC = 11\)
\(MN = 9\)
Required
Find AB
Since MN is the midpoint, then:
\(MN = \frac{1}{2}(AB + DC)\)
\(9 = \frac{1}{2}(AB + 11)\)
Multiply by 2
\(2 * 9 = \frac{1}{2}(AB + 11)*2\)
\(18 = AB + 11\)
\(AB = 18 - 11\)
\(AB = 7\)
You and two friends go to eat pizza there are two deals 10% off of 1 pizza or 30% off of 3 pizzas. Do you want to each pay separately and get 10% off of your bill or do you want to spl it the bill 3 wa
Answer:
Step-by-step explanation:
Assuming the price of 1 pizza is $x. Total number of pizzas is 3.
Considering the first deal,
10% off your pizza is 10/100 × x = 0.1x. The amount that you will pay is x - 0.1x = 0.9x
The cost of the remaining two pizzas is 2 × x = 2x
The total amount to be paid is
2x + 0.9x = $2.9x
Considering the second deal, 30% off the bill would be
30/100 × 3x = 0.9x
The amount to be paid is
3x - 0.9x = $2.1x
Therefore, I prefer the second deal

Based on the lengths of the segments in the ellipse below, how long is the major axis of the ellipse? Show your work.
Check the picture below.
the distances d1 and d2 are for this ellipse 7 and 3 respectively, keeping in mind that their sum is always the same, namely d1 + d2 is always the same 10 no matter where on the ellipse you move the point, notice in the picture, if we move d1 to the extent that lies flat right on top of d2, we have the length of d1 in purple, plus the length of d2, which we later colored in darkyellow, if we move d2 to the right-hand-side or the tail of d1, we'd end up with the ellipse's major axis, which is oddly enough, d1 + d2.

what is the conditional probability that a randomly-generated 4-bit string contains two consecutive 1s, given that the first bit of the string is a 1?
The conditional probability that a randomly-generated 4-bit string contains two consecutive 1s is 3 / 8 .
total length of four-bit strings = 16
Let S represent the collection of all four-bit bit strings.
Let A represent the occurrence of a randomly generated string beginning with 1.
Let B represent the scenario where a string created at random contains two consecutive 0s.
S has 8 strings that begin with the letter "1."
P( A ) = 8 / 16 = 1 / 2
Strings in S starting with 1 and having two consecutive zeros are 1000 , 1001 , 1100
P(A ∩ B) = 3 / 16

Find the first and second derivatives. 5 y = - 4x® - 9 11
We are given a function y = -4x^3 - 9x^11, and we need to find its first and second derivatives.
To find the first derivative, we apply the power rule and the constant multiple rule. The power rule states that the derivative of x^n is nx^(n-1), and the constant multiple rule states that the derivative of kf(x) is k*f'(x), where k is a constant. Applying these rules, we can find the first derivative of y = -4x^3 - 9x^11.
Taking the derivative term by term, the first derivative of -4x^3 is -43x^(3-1) = -12x^2, and the first derivative of -9x^11 is -911x^(11-1) = -99x^10. So, the first derivative of y is dy/dx = -12x^2 - 99x^10.
To find the second derivative, we apply the same rules to the first derivative. Taking the derivative of -12x^2, we get -122x^(2-1) = -24x, and the derivative of -99x^10 is -9910x^(10-1) = -990x^9. Therefore, the second derivative of y is d^2y/dx^2 = -24x - 990x^9.

What does it mean if the graph is skewed to the right?
If the histogram is skewed to the right, the graph's peak will be to the left of the center.
What happens when the distribution is skewed to the right?The peak of the graph is located to the left of the center if the histogram is skewed to the right. The frequency of observations is less frequent on the right side of the graph than it is on the left.
The mean is typically higher than the median when the distribution is right-skewn. We anticipate that the mean and median will be roughly identical in value in symmetric distributions. There is a significant link between the distribution's form and how the mean and median are related.
A positively skewed distribution, sometimes referred to as a right-skewed distribution, is a type of distribution where the majority of values are concentrated around the left tail and the right tail is longer. The distribution that leans positively is the exact opposite of one that leans negatively.

[-b + √(b² -4ac)]/2a
a = 2, b = 8, c = 5
Substituting the values into the expression
[-b + √(b² -4ac)]/2a
= [-8 + √((8)² - 4(2)(5))]/2(2)
= [-8 + √(64 - 40)]/4
= [-8 + √(24)]/4
= [-8 + 2√6]/4
= -2 + 1/2(√6)
= -0.775
≈ -0.8

S = 2πrh + 2πr²
r = 2.3, h = 7.1 (Take π = 3.14)
Thus,
S = 2(3.14)(2.3)(7.2) + 2(3.14)(2.3)²
S = 103.9968 + 33.2212
S = 137.218

Step-by-step explanation:
negative four raised to the sixth power divided by negative four raised to the fourth power
because negative four raised to the fourth power divided by negative four raised to the second power = negative four raised to the second power
negative four raised to the sixth power divided by negative four raised to the fourth power also = negative four raised to the second power
The answer is A: negative four raised to the second power divided by negative four raised to the fourth power. This is obtained by applying the rules of exponents, specifically, when dividing with the same base, subtract the exponents.
Explanation:This question pertains to exponents division rules. According to the rule of Power of a Power in exponents, when you divide expressions with the same base, you subtract the exponents. So if you have negative four raised to the fourth power (-4⁴) and you want to divide it by negative four raised to the second power (-4²), you subtract 2 from 4 to get an exponent of 2. This results in a negative four raised to the second power (-4²). So, the correct option from the given choices in your question is A: negative four raised to the second power divided by negative four raised to the fourth power.

Determine the smallest integer value of x in the solution of the
Following inequality.
2x - 82 -11
The smallest integer is 1 and solution is (₋1)
Given, the inequality is 2x ₋ 8 ≥ ₋11
The mathematical expressions with inequalities are those with unequal sides on both sides. Unlike equations, we compare two values when we work with inequality. A statement that two things are not equal is what is meant by the word "inequality." It's possible for one of the items to be more than, smaller than, equal to, or equal to the other things.
now add 8 on both sides.
2x ₋ 8 ₊ 8 ≥ ₋11 ₊ 8
2x ≥ ₋3
dividing both sides by 2.
2x/2 ≥ ₋3/2
⇒ x ≥ ₋3/2
₋3/2 is not an integer.
hence the smallest integer value of x is 1, and solution is (₋1)
Hence we get the integer value as 1.

Chemical B is plotted on the vertical axis using the scale of 1 cm to represent 2 units. Chemical A is plotted on the horizontal axis using the scale of 1 cm to represent 1 unit.
Therefore, on the graph, the line passing through the origin of the graph shows that when 1.4 g of Chemical A is used 1.6 g of Chemical B is needed.
