Answer:

2 1/2

Step-by-step explanation:

20/8=2r4

2r4= 2 4/8

2 4/8 = 2 1/2

Answer:

2 1/2

Step-by-step explanation:

Step 1:

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

20/8= 2.5 = 2

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (2) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:

20 - (8 x 2) = 4

Step 3: Our mixed fraction

We've now simplified 20/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

2 4/8

Step four: Convert it by simplifying

2 4/8 = 2 1/2

The chance that both numbers drawn are even numbers is 8/21.

The probability refers to the measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain.

There are 4 even numbers and 3 odd numbers in the first box, and 2 even numbers and 1 odd number in the second box.

The probability of drawing an even number from the first box is 4/7, and the probability of drawing an even number from the second box is 2/3.

By the multiplication rule of probability, the probability of drawing an even number from both boxes is

(4/7) × (2/3) = 8/21

Answer:

57%

Step-by-step explanation:

Answer:

.57 or 57%

Step-by-step explanation:

If a basketball player has a free-throw shooting percentage of 43%, it means that she makes 43% of her free throws on average. Therefore, the probability that she will miss her next free throw is equal to the complement of her shooting percentage, which is 1 minus 0.43. This simplifies to 0.57 or 57%. So, the probability that she will miss her next free throw is 57%.

Answer:

D

Step-by-step explanation:

First, let's calculate the initial monthly payment without purchasing any points.

The amount of the mortgage after the 20% down payment is:

$125,000 x 0.8 = $100,000

To calculate the monthly payment, we can use the formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]

Where:

M = Monthly payment

P = Principal (loan amount)

i = Interest rate (per month) = 4.75% / 12 = 0.0039583

n = Number of payments = 30 years x 12 months per year = 360

So, plugging in the values:

M = $100,000 [ 0.0039583(1 + 0.0039583)^360 ] / [ (1 + 0.0039583)^360 – 1]

M = $522.12 (rounded to the nearest cent)

Now, let's calculate the new monthly payment if Ashlee purchases 2 points. Each point costs 1% of the loan amount, so for a $100,000 loan, each point is $1,000.

By purchasing 2 points, Ashlee would pay an additional $2,000 upfront (2 x $1,000). This will lower the interest rate on the loan by 0.5%, from 4.75% to 4.25%.

Using the same formula as before, but with the new interest rate of 4.25% / 12 = 0.0035417, we get:

M = $100,000 [ 0.0035417(1 + 0.0035417)^360 ] / [ (1 + 0.0035417)^360 – 1]

M = $505.16 (rounded to the nearest cent)

The difference in monthly payments is:

$522.12 - $505.16 = $16.96

Rounding to the nearest cent, the answer is option D, $14.96.

Answer:

71.9 degrees

Step-by-step explanation:

The find the value of x on the given diagram, we must first find the included angle between the two line segments labelled 94 mi and 119 mi in the triangle. To do this, we can use the Law of Cosines.

[tex]\boxed{\begin{minipage}{6 cm}\underline{Law of Cosines} \\\\$c^2=a^2+b^2-2ab \cos C$\\\\where:\\ \phantom{ww}$\bullet$ $a, b$ and $c$ are the sides.\\ \phantom{ww}$\bullet$ $C$ is the angle opposite side $c$. \\\end{minipage}}[/tex]

The values to substitute into the formula are:

Solving for the angle C:

[tex]\begin{aligned}173^2&=119^2+94^2-2(119)(94)\cos C\\\\29929&=14161+8836-22372\cos C\\\\29929&=22997-22372\cos C\\\\6932&=-22372\cos C\\\\-\dfrac{6932}{22372}&=\cos C\\\\C&=\cos^{-1}\left(-\dfrac{6932}{22372}\right)\\\\C&=108.0502874...^{\circ}\end{aligned}[/tex]

As angles on a straight line sum to 180°, the value of x can be calculated by subtracting the found value of C from 180°:

[tex]x=180^{\circ}-108.0502874...^{\circ}[/tex]

[tex]x=71.9497125...^{\circ}[/tex]

[tex]x=71.9^{\circ}\; \sf (nearest\;tenth)[/tex]

Answer: 90 feet

Step-by-step explanation:

Since the baseball diamond is shaped like a square, all sides are equal in length.

Let's denote the length of each side by x.

The perimeter of a square is the sum of the lengths of all four sides, so we can write:

4x = 360

Dividing both sides by 4, we get:

x = 90

Therefore, each side of the baseball diamond is 90 feet long.

By answering the presented question, we may conclude that so by SAS congruency property we have said that all these triangles are similar.

A triangle is a closed, a double geometric shape made up of three line segments known as sides that connect at three parameters known as vertices.

Triangles are differentiated by their angles and their sides. Triangles can be collinear (all sides equal), angles, or scalene dependent on their sides.

Triangles are classed as acute (all angles just under 90 degrees), right (one angle of approximately to 90 degrees), or ambiguous (all angles greater than 90 degrees).

The area of a triangle may be determined with the formula A = (1/2)bh, where A is the surface, b is really the right triangle base, and h is the triangle's height

here, from the figure, we have

Two sides of the triangle are equal.

Answer:

102 and 87

Step-by-step explanation:

Let the two numbers be x and y.

x+y = 189

x-y =15

Add the two equations together.

x+y = 189

x-y =15

-------------------

2x =204

2x/2 = 204/2

x = 102

Now we can find y.

x+y = 189

102+y =189

y = 189-102

y =87

Answer: We know that the center of the ellipse is the midpoint of the line segment joining the foci. So, the center is ((15+3)/2, (-2-2)/2) = (9, -2).

The distance between the foci is 2c, where c is the distance between the center and each focus. So, 2c = 15 - 3 = 12, which means c = 6.

The distance between the center and each co-vertex is b. So, b = 10 - (-2) = 12.

The semi-major axis is a, which is the distance from the center to a vertex. Since we have the co-vertices, we can use the Pythagorean theorem to find a:

a^2 = b^2 - c^2

a^2 = 12^2 - 6^2

a^2 = 108

a = sqrt(108) = 6*sqrt(3)

Therefore, the equation of the ellipse is:

(x - 9)^2 / (6*sqrt(3))^2 + (y + 2)^2 / 12^2 = 1

Simplifying, we get:

(x - 9)^2 / 72 + (y + 2)^2 / 144 = 1

So, the equation of the ellipse is (x - 9)^2 / 72 + (y + 2)^2 / 144 = 1.

Geometric argument,

a and b are nonzero vectors that are not parallel.

A plane in three-dimensional space.

Any vector in this plane can be written as a linear combination of a and b.

Let c be any vector in this plane.

Construct a parallelogram with sides a and b, and the diagonal of the parallelogram passing through the point c.

This diagonal is the vector c written as a linear combination of a and b, say c = sa + tb for some scalars s and t.

Diagonal of a parallelogram bisects and is bisected by its opposite sides.

c lies on the line passing through the midpoints of a and b.

c can be expressed as a linear combination of a and b.

Argument using components,

a and b are nonzero vectors that are not parallel, they are linearly independent.

Any vector in the plane determined by a and b can be expressed as a linear combination of a and b.

Let c = (c1, c2, c3) be any vector in this plane.

Now, c as c = sa + tb, where s and t are scalars to be determined.

Writing a and b in terms of their components, we have,

a = (a1, a2, a3) and b = (b1, b2, b3)

Then, we can write c as,

c = (s a1 + t b1, s a2 + t b2, s a3 + t b3)

Values of s and t such that c has the components (c1, c2, c3).

Equating the components of c with those of (c1, c2, c3), to get the system of equations,

Step-by-step explanation:

We can use the formula distance = rate x time to solve the problem.

The rate is 15 miles per hour and the time is 3 1/3 hours.

To work with the time, we need to convert it to an improper fraction:

3 1/3 = (3 x 3 + 1)/3 = 10/3

Probability is a branch of mathematics that deals with the study of randomness and uncertainty in events. It is the measure of the likelihood or chance that an event will occur. Probability is expressed as a number between 0 and 1, where 0 indicates that the event will not occur and 1 indicates that the event will occur with certainty.

The problem states that each of the three competitors picked 1 pound of strawberries. Since all of them picked the same amount, there is no way to determine who came in second. All three competitors can be considered tied for first place. If the problem had given different weights of strawberries picked by each competitor, then we could have compared the weights and determined who picked the second greatest amount of strawberries. But since all three competitors picked the same amount, there is no way to determine a second place winner.

Therefore,  there is no second place winner. all three competitors picked the same amount of strawberries, so there is a tie for first place.

If the zeros and their multiplicities are given, we can write the polynomial as the product of linear factors corresponding to each zero.

For this problem, the polynomial has zeros of -9 (multiplicity 1) and -1 (multiplicity 2), so the linear factors are:

(x + 9) and (x + 1)^2

To find the third factor, we use the fact that the degree of the polynomial is 3. We can multiply the linear factors together and then simplify:

(x + 9)(x + 1)^2 = (x^2 + 10x + 9)(x + 1)

= x^3 + 11x^2 + 19x + 9

Therefore, the polynomial with zeros of -9 (multiplicity 1), -1 (multiplicity 2), and degree 3 is:

f(x) = x^3 + 11x^2 + 19x + 9

Probability is a branch of mathematics concerned with measuring the likelihood or chance of an event occurring. It is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes. Probability is expressed as a number between 0 and 1, where 0 means that the event will not occur and 1 means that the event will definitely occur. For example, if the probability of an event is 0.5, it means that the event has an equal chance of occurring or not occurring. Probability is used in various fields, such as science, engineering, finance, and statistics, to make predictions and make decisions based on uncertain events.

Part A:

Answer:

We can use the formula |a × b| = |a| |b| sin θ to solve for the magnitude of the cross product |a × b|, where θ is the angle between vectors a and b. In this case, we have |a × b| = 1 and θ = π/4, so we can write:

1 = |a| |b| sin(π/4)

Simplifying, we have:

|a| |b| = √2

Now, we need to find the dot product a · b. We know that:

a · b = |a| |b| cos θ

where θ is the angle between vectors a and b. Since we're given the angle between a and b, we can substitute θ = π/4 and use the value we found for |a| |b|:

a · b = (√2) cos(π/4) = (√2)/2

Answer: We are given that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C.

To find the probability of obtaining a reading between 0°C and 1.08°C, we need to calculate the z-scores for these values using the formula:

z = (x - mu) / sigma

where x is the value we are interested in, mu is the mean, and sigma is the standard deviation.

For x = 0°C, we have:

z1 = (0 - 0) / 1.00 = 0

For x = 1.08°C, we have:

z2 = (1.08 - 0) / 1.00 = 1.08

Using a standard normal table or a calculator, we can find the probability of obtaining a z-score between 0 and 1.08.

Using a standard normal table or a calculator, we find that the probability of obtaining a z-score between 0 and 1.08 is 0.3583.

Therefore, the probability of obtaining a reading between 0°C and 1.08°C is 0.3583, rounded to 4 decimal places.
