-2/5(5-10e) = e + 1/3(6e-12)
Step-by-step explanation: To solve for e in this equation, you can start by isolating e on one side of the equation.
First, distribute the -2/5 on the left side of the equation:
-2/55 - 2/510e = e + 1/36e - 1/312
Now, you can combine like terms on both sides of the equation:
-2 - 4e = e + 2e - 4
Next, you can add e to both sides of the equation:
-2 - 3e = 2e - 4
Now you can add 3e to both sides of the equation:
-2 = 5e - 4
Now you can add 4 to both sides of the equation:
-6 = 5e
Finally, you can divide both sides of the equation by 5:
e = -6/5
So the value of e that satisfies the equation is -6/5.
suppose that shoe sizes of american women have a bell-shaped distribution with a mean of 8.04 and a standard deviation of 1.53 . using the empirical rule, what percentage of american women have shoe sizes that are less than 11.1 ?
The percentage of American women that have shoe sizes that are at least 11.1 is; 0.0015
Empirical Rule
We are given;
Mean; x' = 8.04
Standard deviation; σ = 1.53
Using the empirical rule, we can have the data either 1, 2, or 3 standard deviations from the mean.
Thus;
At 1 standard deviation from the mean, we have;
8.04 ± 1(1.53)
⇒ (6.52, 8.56)
At 2 standard deviations from the mean, we have;
8.04 ± 2(1.53)
⇒ (5, 11.08)
At 3 standard deviations from the mean, we have;
8.04 ± 3(1.52)
⇒ (3.48, 12.6)
We can see that the one with at least 12,6 is 3 standard deviations from the mean which from the empirical rule is 99.7%
Thus;
percentage of American women have shoe sizes that are at least 12.6 = 100% - 99.7% - 0.15%
P(x ≥ 12.6) = 0.15% = 0.0015

What is a Rhombus and Trapizium ?A quadrilateral called a rhombus has four equal-length sides. The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.
A parallelogram's general characteristics are as follows:
Angles on the opposite sides are congruent or equal.The opposing sides are parallel and equal in size.Diagonals cut each other in half.Any two parallel or following angles add up to 180 degrees.In American and Canadian English, a quadrilateral having at least one set of parallel sides is referred to as a trapezoid. It is referred to as a trapezium in British and other varieties of English. In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides.
The area of a rhombus = ½ x (product of the lengths of the diagonals)

The ratio of Mary's share to Katherine's share to Alex's share is 5:4:1, which means Mary pays 5/10 of the bill, Katherine pays 4/10 of the bill, and Alex pays 1/10 of the bill.
To find the ratio, we can write their contribution as a fraction of the total parts and then solve the fractions then they'll have the same denominator.
So, Mary's share is 5/10, Katherine's share is 4/10, and Alex's share is 1/10.
To convert this as a ratio, we write 5:4:1, where each number represents the number of parts each person pays, and the colon separates each person's contribution.

The age of Lisa and Myra now is 35 years old and 5 years old, respectively.
To determine how old each person now, use algebraic expression and equation.
Let x = current age of Lisa
y = current age of Myra
If the sum of Lisa's age and Myra's age is 40, then we can express it as:
x + y = 40
x = 40 - y
If in 10 years, Lisa will be 3 times as old as Myra, then we can express it as:
x + 10 = 3(y + 10)
x + 10 = 3y + 30
x - 3y = 20
Substitute the equation for x into the 2nd equation and solve for y.
x - 3y = 20
(40 - y) - 3y = 20
40 - 4y = 20
4y = 20
y = 5
Substitute the value of y into the equation for x and solve.
x = 40 - y

At a pizza shop, 6 slices of pizza and 2 drinks cost the same as 5 slices of pizza and 5 drinks. Each slice of pizza costs $4.50. Find the cost in dollars of each drink.
Answer:

Step-by-step explanation:
Let d = the cost of a drink
6(4.50) + 2d = 5(4.5) + 5d Distribute the 6 and 5
27 + 2d = 22.50 + 5d Subtract 2d from both sides
27 + 2d - 2d = 22.50 + 5d - 2d
27 = 22.50 + 3d Subtract 22.50 from both sides
4.5 = 3d Divide both sides by 3

The variance of 'x' for the continuous distribution over the interval 40 to 44 is approximately b) 1.333
The variance of a continuous uniform distribution over the interval [a, b] is:
Calculate the variance using the formula:
Var(x) = (b-a)^2/12
where [a, b] is the interval over which the continuous uniform distribution is defined
But putting a= 40 and b = 44, calculate the variance by putting them in the above formula
So, Var(x) = (44-40)^2/12
Var(x) = 4^2/12
Var(x) = 16/12
Var(x) = 4/3
Var(x) = 1.333

3a³b² - 5a³b² = -2a³b² --> both exponents are already equal
5xy - 2x²y + 2xy = 7xy - 2x²y
= xy (7 - 2x)
-6w : -2w = 3
a⁴ . a³ = a⁽⁴⁺³⁾
= a⁷
(-x⁵)² = - x ⁽⁵ˣ²⁾
= - x¹⁰
k⁹ / k⁵ = k⁽⁹⁻⁵⁾
= k⁴
-5x³ . (-3x⁴) = 15x⁷
(-2x²y)² . (-3xy³) = (4x⁴y²) . (-3xy³)
= -12x⁵y⁵
2a⁻⁵b⁶ . 5a²b² = 10 a⁻³b⁸
= 10b⁸ / a³
(-4y⁴)² = 16y⁸
(a²bc³)⁴ . (b²c)³ = (a⁸b⁴c¹²) . (b⁶c³)
= a⁸b¹⁰c¹⁵
(6cd⁻¹)⁻³ = 1 / (6cd⁻¹)³
= (d/6c)³
= d³ / 216c³
(4a)⁻³ . a⁻⁴ = 1/(4a)³ . (1/a⁴)
= 1/64a³ . 1/a⁴
= 1/64a⁷
(3xy)² . (-4x³y²)³ = (9x²y²) . (-64x⁹y⁶)
= -576x¹¹y⁸
(4a⁻¹b⁵c⁻³)³ = (4b⁵ / ac³)³
= 64b¹⁵ / a³c⁹
9d⁸/3d¹⁰ = 3/d²
6a⁵b² / 4ab³ = 3a⁴/ 2b
32x³y²z⁵ / -8xyz² = -4x²yz³
(2y⁵)⁴ / 10y¹⁵ = 16y²⁰ / 10y¹⁵
= 8y⁵ / 5
(3x⁵y³ / x³y⁶)⁴ = (3x²/y³)⁴
= 81x⁸ / y¹²
(-6a⁵b)² - 8a³b = 36a¹⁰b² - 8a³b
12a⁷b 12a⁷b
= 3a⁵b - 8a⁵b
= -5a⁵b
