To find the number of days it will take for Juliana's investment to grow, we can use the formula for simple interest

I = P * r * t.

I = interest earned
P = principal amount (initial investment)
r = interest rate per year (in decimal form)
t = time in years In this case,

Juliana's principal amount (P) is $3,300, the interest rate (r) is 6.25% or 0.0625, and she wants to reach $3,450. We need to solve for t. $3,450 = $3,300 * 0.0625 * t Divide both sides of the equation by ($3,300 * 0.0625) to isolate t:
t = $3,450 / ($3,300 * 0.0625)
t = 17 So it will take Juliana approximately 17 days for her investment to grow to $3,450.

The probability of rolling a sum greater than 12 or a sum that is an odd number after rolling two balanced and fair dice is 47/96.What is the probability of rolling a sum greater than 12 or a sum that is an odd number?The given information says that there are two balanced and fair dice. One is a six-sided die, and the other is an eight-sided die. We need to find the probability of rolling a sum greater than 12 or a sum that is an odd number after rolling the two dice.It's necessary to know the possible outcomes of the dice game when two dice are rolled. The 6-sided die has possible outcomes {1,2,3,4,5,6}, and the 8-sided die has possible outcomes {1,2,3,4,5,6,7,8}.The possible outcomes for each sum from 2 to 14 are shown below in the following table:The sum of the faces is odd if only one of the dice has an even number. In contrast, the sum of the faces is even if both dice have an even number. The red color represents the sum of the faces, which is an odd number, while the blue color represents the sum of the faces, which is an even number. Now we can easily calculate the total number of sums that are either greater than 12 or an odd number. It is important to note that the sum of 2 and 4 is even, and the sum of 13 and 14 is greater than 12. So the total number of sums that are either greater than 12 or an odd number is: 1 + 4 + 1 + 6 + 8 + 8 + 6 + 1 + 4 + 1 = 40It's also necessary to calculate the total number of possible outcomes when rolling two dice. The number of possible outcomes when rolling two dice is 6 x 8 = 48.We now have everything we need to find the probability of rolling a sum greater than 12 or a sum that is an odd number:Probability = Number of favorable outcomes / Total number of possible outcomes= 40/48 = 5/6Therefore, the probability of rolling a sum greater than 12 or a sum that is an odd number is 5/6.

Answer:

y  >  2  −  x

Step-by-step explanation:

The expected claim size is 950 and the variance is 125000/9.

The probability that a claim is no greater than 500 is 0.8, which means the probability of a claim being greater than 500 is 0.2. The claim sizes are uniformly distributed on (0; 500] and on (500; 1500].

Therefore, the probability of a claim being in the range of (0; 500] is 0.8/2 = 0.4 and the probability of a claim being in the range of (500; 1500] is 0.2/2 = 0.1.

The expected claim size is calculated as the weighted average of the claim sizes in each range, where the weight is the probability of a claim being in that range. Thus, the expected claim size is (0.4 x 250 + 0.1 x 1000) = 950.

The variance of the claim size is calculated as the weighted average of the squared deviations from the expected claim size, where the weight is the probability of a claim being in that range. Thus, the variance is (0.4 x (250 - 950)^2 + 0.1 x (1000 - 950)^2) = 125000/9.

Therefore, the expected claim size is 950 and the variance is 125000/9.

i. Vectors u and w are orthogonal.

ii. The two vectors orthogonal to v = √(2, -3) are u = (3, 2) and w = (-2, 3).

iii. The two unit vectors orthogonal to 7 are u = (1, -1) / √2 and w = (1, 1) / √2.

i. To show that vectors u = (a, b) and w = (-b, a) are orthogonal, we need to demonstrate that their dot product is zero.

The dot product of u and w is given by:

u · w = (a, b) · (-b, a) = a*(-b) + b*a = -ab + ab = 0

ii. To find two vectors orthogonal to vector v = √(2, -3), we can use the result from part i.

Let's denote the two orthogonal vectors as u and w.

We know that u = (a, b) is orthogonal to v, which means:

u · v = (a, b) · (2, -3) = 2a + (-3b) = 0

Simplifying the equation:

2a - 3b = 0

We can choose any values for a and solve for b. For example, let's set a = 3:

2(3) - 3b = 0

6 - 3b = 0

-3b = -6

b = 2

Therefore, one vector orthogonal to v is u = (3, 2).

To find the second orthogonal vector, we can use the result from part i:

w = (-b, a) = (-2, 3)

iii. To find two unit vectors orthogonal to 7, we need to consider the dot product between the vectors and 7, and set it equal to zero.

Let's denote the two orthogonal unit vectors as u and w.

We know that u · 7 = (a, b) · 7 = 7a + 7b = 0

Dividing by 7:

a + b = 0

We can choose any values for a and solve for b. Let's set a = 1:

1 + b = 0

b = -1

Therefore, one unit vector orthogonal to 7 is u = (1, -1) / √2.

To find the second unit vector, we can use the result from part i:

w = (-b, a) = (1, 1) / √2

Blake can purchase approximately 60.75 pounds of Cheese Filled Lizards and 10 dozen of Fried Frog Skins with the $432 he saved by recycling old aluminum cans.

First we need to set up some equations.

Let's denote the amount of Cheese Filled Lizards in pounds as "c" and the number of dozen Fried Frog Skins as "f". We can then set up the following system of equations:

8c + 6f = 432 (the total cost of the party is $432)

12f = k (the number of Fried Frog Skins in individual pieces, k is an unknown constant)

To solve for "c" and "f", we need to eliminate one of the variables. We can do this by solving the second equation for "f" and substituting it into the first equation:

f = k/12

8c + 6(k/12) = 432

8c + (1/2)k = 432

16c + k = 864

Now we have a single equation in two variables. We can choose one of the variables and solve for it in terms of the other. For example, solving for "k" in terms of "c", we get:

k = 864 - 16c

Substituting this expression for "k" into the equation 12f = k, we get:

12f = 864 - 16c

f = (72/4) - (4/3)c

f = 18 - (4/3)c

So we have expressed the number of Fried Frog Skins in terms of the amount of Cheese Filled Lizards. We can now substitute this expression into the cost equation:

8c + 6(18 - (4/3)c) = 432

Solving for "c", we get:

8c + 108 - 8c/3 = 432

16c/3 = 324

c = 60.75

So, Blake can purchase approximately 60.75 pounds of Cheese Filled Lizards and 10 dozen of Fried Frog Skins with the $432 he saved by recycling old aluminum cans.

Answer:

polygon has 12 sides

Step-by-step explanation:

the sum of the exterior angles of a polygon is 360°

the sum of the interior angles of a polygon is

sum = 180° (n - 2 ) ← n is the number of sides

given the sum of the interior angles is 5 times sum of exterior angles, then

sum = 5 × 360° = 1800° then

180° (n - 2) = 1800 ( divide both sides by 180 )

n - 2 = 10 ( add 2 to both sides )

n = 12

Thus the polygon has 12 sides

The region given by the integral \($\int_1^{\sqrt{y}} \int_0^y dx \ dy$\) is a triangle bounded by the x-axis, the line $x = 1$ and the line \($x = \sqrt{y}$. T\)

The integral\($\int_1^{\sqrt{y}} \int_0^y dx \ dy$\) represents a double integral over the region bounded by the x-axis, the line $x = 1$, and the line $x = \sqrt{y}$ in the y-x plane.

To better understand the region described by this integral, let's break it down into two parts: the outer integral \($\int_1^{\sqrt{y}}$\) and the inner integral \($\int_0^y$.\)

The outer integral\($\int_1^{\sqrt{y}}$\) represents the limits of integration for y, which range from 1 to\($\sqrt{y}$\). This means that y varies from 1 to\($\sqrt{y}$\), which describes a region that starts from the point (1,1) on the y-x plane and extends up to the curve\($x = \sqrt{y}$\).

The inner integral\($\int_0^y$\) represents the limits of integration for x, which range from 0 to y. This means that x varies from 0 to y along the y-axis, which describes a region that is bounded by the x-axis, the line $x = 1$, and the line\($x = \sqrt{y}$.\)

Putting these two integrals together, we can visualize the region as a triangle in the y-x plane. The base of the triangle is the line segment from (1,1) to \(($\sqrt{y}$, $\sqrt{y}$)\), and the height of the triangle is the line segment from \(($\sqrt{y}$, 0)\) to \(($\sqrt{y}$, $\sqrt{y}$)\).

Answer:

43200 minutes

Step-by-step explanation:

We start with 30 days.

The following two equations are true

To convert units away from days, we'll want to multiply by an expression that is equal to 1 (so that we don't change the actual amount of time we're measuring) where the units in the denominator (bottom of the fraction) are days, so that they'll cancel with the units of "days" from 30 days.

In the first equation, if we divide both sides by 1 day, we'll get a fraction, equal to 1, with days in the denominator:

\(1 ~day = 24~ hours\)

\(\dfrac{1 ~day}{1 ~day} = \dfrac{24 ~hours}{1 ~day}\)

\(1= \dfrac{24~ hours}{1 ~day}\)

This will cancel units of days, and give an equivalent length of time in hours.

Multiplying by 1 doesn't change anything

\(30~days=30~days*1\)

As shown above, 24 hours divided by 1 day is equal to "1".  Substitute...

\(=30~days*\dfrac{24 ~hours}{1 ~day}\)

Dividing by 1 doesn't change anything...

\(=\dfrac{30~days}{1}*\dfrac{24 ~hours}{1 ~day}\)

Multiply fractions together by multiplying numerators, and multiplying denominators...

\(=\dfrac{30~days~*~24 ~hours}{1*1 ~day}\)

Commutative Property of Multiplication -- switch order of denominator...

\(=\dfrac{30~days~*~24 ~hours}{1 ~day~*~1}\)

Multiplying fractions together is multiplying numerators, and multiplying denominators, so this just pulls those fractions apart...

\(=\dfrac{30~days~}{1 ~day}*\dfrac{24 ~hours}{1}\)

Days divided by Days is like 5 divided by 5.  Any non-zero thing divided by itself is 1, and cancels out...

\(=\dfrac{30}{1}*\dfrac{24 ~hours}{1}\)

Dividing by 1 doesn't change anything...

\(=30~*~24 ~hours\)

Multiply the numbers together...

\(=720~hours\)

From here, we can do a similar process to convert from hours to minutes:

\(720~hours=720~hours*1\)

\(=720~hours*\dfrac{60~minutes}{1~hour}\)

\(=\dfrac{720~hours}{1}*\dfrac{60~minutes}{1~hour}\)

\(=\dfrac{720~hours~*~60~minutes}{1~*~1~hour}\)

\(=\dfrac{720~hours~*~60~minutes}{1~hour~*~1}\)

\(=\dfrac{720~hours}{1~hour}*\dfrac{60~minutes}{1}\)

\(=\dfrac{720}{1}*\dfrac{60~minutes}{1}\)

\(=720*60~minutes\)

\(=43200~minutes\)
