which is the best deal? why?​

If Jim's credit card statement shows a previous balance of $937.20, and he made a payment of $730 and add a new transaction of $502, if his credit card Annual Percentage Rate (APR) is 15%, then his new balance is $1699.20.

To calculate the new balance, the following steps were taken:

Add the previous balance ($937.20) to the new transaction amount ($502.00) to find the current balance before finance charges

$937.20 + $502.00 = $1439.20

Calculate the finance charges by dividing the annual percentage rate (APR) which is 15% by the number of billing periods in a year (usually 12) and then multiplying the result by the average daily balance.

finance charges = (15% / 12 months) × $1439.20

finance charges = $17.49

Add the finance charges to the current balance before finance charges to find the new balance:

$1439.20 + $17.49 = $1656.69

Finally, subtract the payment amount ($730) from the new balance ($1656.69) to find the updated balance:

$1656.69 - $730 = $1699.20.

Therefore, Jim's new balance is $1699.20.

The probability of the value of p(a ∩ bc ) is 1/54

Probability is a mathematical measure of how likely an event is to occur.

Given that p(a ∪ b) = 2/3, which means the probability of either event a or event b happening is 2/3, we can find the probability of a and b happening simultaneously using the formula for conditional probability.

=> p(a ∩ b) = p(a | b) * p(b) = 1/12,

where p(a | b) is the probability of event a happening given that event b has already happened. We can use this information to find p(b) as follows:

=> p(b) = p(a ∩ b) / p(a | b) = 1/12 / p(a | b)

We also know that p(b ∩ ac) = 1/3, which means the probability of both events b and ac happening is 1/3. We can use this information to find p(b) and p(a | b).

=> p(b) = p(b ∩ ac) / p(ac | b) = 1/3 / p(ac | b)

Finally, using the formula for conditional probability, we can find p(a ∩ bc) as follows:

p(a ∩ bc) = p(a | bc) * p(bc) = p(a | b) * p(b | bc) * p(bc) = p(a | b) * p(b) * p(bc | b) * p(bc)

p(a ∩ bc) = 2/3 * 1/12 *1/3 = 1/54

Let's call the amount of sugar needed to make 200 grams of 15% sugar syrup "s".

From the information given, we know that 15% of the syrup is sugar, so 200 grams * 15% = 200 grams * 0.15 = 30 grams of the syrup is sugar.

Therefore, the amount of sugar needed is equal to 30 grams, or s = 30 grams.

A shape must cross a line in order to be reflected.

Because a reflection across BA will map ABC to ABD, the true statement is (c).

A translation only moves a shape up, down, or from side to side; it has no effect on how it appears. An illustration of a transformation is translation. A transformation is a technique for moving or repositioning a shape.

here, we have,

Sides AC and AD of both triangles are congruent

Sides BD and BC of both triangles are congruent

The triangles share a common side AB

This means that a reflection over line AB will map both triangles.

Hence, the true statement is (c)

The complete question is given below.

Is there a rigid transformation that maps triangle ABC to triangle ABD? If so, which transformation?

yes, because a translation to the right will map ΔABC to ΔABD

yes, because a rotation about point B will map ΔABC to ΔABD

yes, because a reflection across BA will map ΔABC to ΔABD

no, because no rigid transformation will map ΔABC to ΔABD

The least number of square pieces that Monica can cut from a rectangular cake without wasting any cake is 15 pieces, each 7 inches on a side.

Monica wants to cut a cake into identical square pieces without wasting any cake. To find the least number of square pieces that can be cut from a rectangular cake, we need to find the greatest common divisor (GCD) of the lengths of the sides.

In this case, the GCD of 21 and 35 is 7. This means that we can cut the cake into 7-inch square pieces, and there will be no waste. The number of pieces can be found by dividing each side of the rectangular cake by the side length of the square pieces.

For the 21-inch side, the number of pieces is

21 / 7 = 3

For the 35-inch side, the number of pieces is

35 / 7 = 5

Therefore, the total number of pieces that can be cut from the rectangular cake is

3 * 5 = 15.

In conclusion, the least number of square pieces that Monica can cut from a rectangular cake without wasting any cake is 15 pieces, each 7 inches on a side.

At time t, the first pool will have 1272 + 31.5t liters of water, and the second pool will have 1600 + 21.25t liters of water.

For the two pools to have the same amount of water, we need:

1272 + 31.5t = 1600 + 21.25t

10.25t = 328

t = 32 minutes

The helix r(t) = (cos(πt/2), sin(πt/2), t) intersects the sphere x² + y² + z² = 2 in two points and the angle of intersection at every point is 0°.

Let's assume that the central axis of the helix is z

Given r(t) = (cos(πt/2), sin(πt/2), t)

Put this point in the sphere equation

cos²(πt/2) + sin²(πt/2) + t² = 2

Δf = (2x, 2y, 2z)

At (cos(πt/2), sin(πt/2), t), Δf = (2cos(πt/2), 2sin(πt/2), 2t)

Angle of intersection at t = 1

Δf = (0, 2, 2) and r = (0, 1, 1)

Using dot product:

                                 θ = 0°

Angle of intersection at t = -1

Δf = (0, -2, -2) and r = (0,-1, -1)

Using dot product:

                           cosθ = (0, -2, 2-).(0, -1, -1)/ √((-2)² + (-2)²) √((-1)² + (-1)²)

                           cosθ = 1

For the function f(x) = tan(x) , the option that cannot be an Asymptote is (a) x = 5π .

An Asymptote is a straight line or curve that a graph approaches but never touches as the input values become larger or smaller.

In mathematical terms, as x approaches positive or negative infinity, the value of the function approaches a fixed constant value or the value of an asymptote.

The function is f(x) = tan(x) ,

the tangent function do not have any horizontal asymptote , and

the vertical asymptotes of tangent function is multiple of π/2 .

the asymptotes of a tangent function are x = π/2 + πn .

Answer:

Below

Step-by-step explanation:

First find the value of the common vertical side

12/v = v/16

v^2 = 192

v = 8 sqrt 3

Now use pyhtag theorem to find x and y

y^2 = 12 ^2 + (8 sqrt3)^2

y = sqrt (336)   = 4 sqrt (21)

now find x the same way

x^2 = 16^2 + (8 sqrt(3))^2 = 448

x = sqrt (448 ) = 8 sqrt 7

The number of color sequences possible when removing five balls one at a time depends on the number of different colors the balls have.

If there are C different colors, the number of color sequences possible is C^5 (C raised to the power of 5), since for each ball you remove, you have C options for its color.

The number of combinations of colors possible when removing five balls one at a time is given by the binomial coefficient "C choose 5", which represents the number of ways to choose 5 balls out of C different balls, ignoring the order in which they are chosen.

The binomial coefficient can be calculated as:

C choose 5 = C! / (5! * (C-5)!).

One possible solution is to define f(x) as the average of g(x) and h(x), which would be: f(x) = (g(x) + h(x)) / 2

The intuition behind this choice is that if f(x) is the average of g(x) and h(x), it should be located between these two functions for all x >= 0. To confirm this, we can graph g(x), h(x), and f(x) on the same coordinate plane and see if they satisfy the inequality.

Variance is a useful tool for gaining a deeper understanding of a dataset beyond just the mean.

Variance is a measure of how far the individual values in a set of data are from the average value.

The variance is calculated by first finding the difference between each value in the dataset and the mean, squaring these differences, and then averaging the squared differences.

The result is a non-negative number that indicates how far, on average, each value deviates from the mean. If the variance is small, it means that most of the values are close to the mean, while a large variance indicates that the values are widely spread out.

One important use of variance is in statistical inference, where it is used to make predictions about a population based on a sample of data. Variance also plays a role in hypothesis testing, where it is used to determine whether the differences between two sets of data are statistically significant.

Answer:

The answer could be x * 33 + 30.

Step-by-step explanation:

In this expression, the parentheses indicate that 14 and 19 are to be added together first, which equals 33. The expression x * 33 means that 33 is being multiplied by x. Finally, 30 is being added to this product. So both expressions represent the same mathematical operation.

Here's how to check our answer:

First, we simplify the expression inside the parentheses:

x(33) + 30

Next, we multiply x and 33:

x * 33 + 30

Finally, we add 30 to the product of x and 33:

x * 33 + 30

So, the expression x * 33 + 30 is equivalent to the expression x(14 + 19) + 30.
