Equivalence means to be same, whether it be value, temperature, size, etc.

Let's take a look at shape 1.

Shape 1 has a base of 3, and a height of 4, but there is a gap with a width of 1 and a height of 2. So, we can use this equation to figure out the area:

So, shape 1 has an area of 10 units.

Let's look at shape 2.

Shape 2 has a base of 2, and a height of 4, but there is also a gap, with a width of 1 and a height of 3. So, we can use this equation to figure out the area:

So, shape 2 has an area of 5 units.

Let's look at shape 3.

Shape 3 consists of 4 right triangles, put together to form an arrowhead. The shape has a base of 4, and a height of 2. So, we can use this equation to figure out the area:

So, shape 3 has an area of 4 units.

Let's look at shape 4.

Shape 4 consists of 4 right triangles, put together to form a diamond. The shape has a base of 4, and a height of 2. So, we can use this equation to figure out the area:

So, shape 4 has an area of 4 units.

Looking to the final shape (5), we can see it consists of a long rectangle and 2 right triangles. Instead of calculating the base and height of the entire shape, we can break it into pieces, making a rectangle that has a base of 3, and a height of 1. Then we are left a shape that has a base of 2, and a height of 3. So, we can use this equation to figure out the area:

So, shape 5 has an area of 6 units.

Let's compare the area of all of the shapes.

Therefore, the two figures that have equal areas are shapes 3 and 4.

The sequence is an arithmetic sequence

The equation of tn is Tn = -k^2 - k + 1 + (n - 1) * (k^2 + 2k + 3)

From the question, we have the following parameters that can be used in our computation:

-k^2 - k + 1, k + 2, k^2 + 3k + 3, 2k^2 + 5k + 4

The above sequence is an arithmetic sequence

And the common difference (d) is

d = k + 2 + k^2 + k + 1

d = k^2 + 2k + 3

The nth term is then calculated as

Tn = a + (n - 1)d

So, we have

Tn = -k^2 - k + 1 + (n - 1) * (k^2 + 2k + 3)

Yes, Jerome's prediction is true that customers will draw a 10% discount coupon one-sixth of the time.

The possibility of the result of any random event is known as probability. This phrase refers to determining the likelihood that any given occurrence will occur.

Yes, Jeremore is correct.

It is given that a box has

Number of 10% discount coupons = 5

Number of 15% discount coupons = 8

Number of 20% discount coupons = 7

Number of 25% discount coupons = 6

Number of 40% discount coupons = 4.

The total coupons in the box = 5+8+7+6+4 = 30.

So, the probability that the customer will get a 10% coupon is

Number of 10% coupons/ Total coupons = 5/30= 1/6.

So, Jerome's prediction is true that customers will draw a 10% discount coupon one-sixth of the time.

When given expression (4x⁴-7x³+7x²-12x+15)/(x-1) is solved, result in the form q(x)+r(x)/b(x) will be -7x² + 4 + 19/(x-1).

Expressions in mathematics are mathematical statements that are made up of at least two sentences that contain numbers, variables, or both, and are connected by an operator. Addition, subtraction, multiplication, and division are examples of mathematical operations. For example, x + y is an equation that separates the terms x and y by an addition operator. There are two sorts of expressions in mathematics: numerical expressions, which include simply numbers, and algebraic expressions, which contain both numbers and variables.

e.g. A number is 6 times larger than another number, x. This statement may be expressed mathematically as x/2 + 6. Complex issues are solved using mathematical expressions.

Now,

Given expression to solve is (4x⁴-7x³+7x²-12x+15)/(x-1)

then dividing this

=4x⁴/x-1-7x³/x-1+7x²/x-1-12x/x-1+15/x-1

=4x³-3x²+4x-8+7/x-1  in form of  q(x)+r(x)/b(x)

= 4x⁴/x-1-7x³/x-1+7x²/x-1-12x/x-1+15/x-1

= -7x² + 4 + 19/(x-1)

hence,

          When given expression (4x⁴-7x³+7x²-12x+15)/(x-1) is solved, result in the form q(x)+r(x)/b(x) will be -7x² + 4 + 19/(x-1).

The probability that a randomly selected adult has an IQ less than 140 is 97.72%.

What is the standard deviation?

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the set mean.

Given that the mean of adults' IQ is μ=100 and the standard deviation is σ=20.

The formula of z-score is z = (X - μ)/σ

Putting the value of μ = 100, σ=20, and X = 140:

z = (140 - 100)/20

z = 40/20

z = 2

From z table, we get the value of z is 0.9772 = 97.72%

P(X<140) = P(z = 2.0) = 97.72%

Answer: $135

Step-by-step explanation:

We have the ratio 1 : 3.

Kim gets $90 more than Jake.

So 1 : 3 can also be written as x : x+90

If x * 3 equals x+90, we can create the equation 3x=x+90. Solving this results in x being equal to 45

Kim gets $135 (x+90=45+90=135)

The mean, median, range, and standard deviation are all measures that can be used to calculate information about a set of numbers, such as the ages of ten randomly selected students.

The mean is the result of totaling the ages of ten randomly selected students and then dividing by ten. This calculation is also known as the average. To calculate the mean, first add up all of the ages, which gives us the sum. Then divide the sum by the number of students, which in this case is 10. The result is the mean, or the average age of the group.

The median is the middle value of a group of numbers. To calculate the median, first put the ages in order from least to greatest. Then find the middle value. If there is an even number of values, then the median is the average of the two middle values.

The range is the difference between the highest and lowest values. To calculate the range, just subtract the smallest number from the largest.

The standard deviation is a measure of variation in a set of numbers. To calculate standard deviation, first subtract the mean from each value, then square each of those differences. Add up these squared differences and divide by the number of values. Then take the square root of that number. The result is the standard deviation.

The probability that a student choosen at random likes english but not maths is 299/676.

Let A be the event that a student likes math, and B be the event that a student likes English.

From the given information, we know that:

P(A) = 15/26

P(B) = 13/26

P(neither A nor B) = 9/26

To find the probability that a student chosen at random likes English but not math, we can use the formula:

P(B and not A) = P(B) - P(A and B)

The probability of A and B can be found by multiplying the probabilities of A and B together, since they are not independent:

P(A and B) = P(A) × P(B) = (15/26) × (13/26) = 195/676

Substituting the given probabilities into the formula, we get:

P(B and not A) = (13/26) - (195/676)

Simplifying, we get:

P(B and not A) = 299/676

Therefore, the probability that a student chosen at random likes English but not math is 299/676.

After finding the sides of the triangle using sine law, we found that the height of the flagpole is found to be 110.89 ft.

What is meant by sine law?

The law of sines specifies how many sides there are in a triangle and how their individual sine angles are equal. The sine law, sine rule, and sine formula are additional names for the sine law.

The side or unknown angle of an oblique triangle is found using the law of sine. Any triangle that is not a right triangle is referred to as an oblique triangle. At least two angles and their corresponding side measurements should be used at once for the sine law to function.

Given,

 The distance between two observers = 600 ft

The angle of elevation of the first observer = 19°

The angle of elevation of the second observer = 21°

We are asked to find the height of the flagpole.

The figure is given below.

There are 2 right triangles, ΔABD and ΔCBD.

We will start with ΔABC.

∠B = 180 - (∠A+∠C) = 180 - (21+19) = 140

Now using sine law, we can find lengths a and b.

According to sine law,

b/sin21 = a/sin 19 = 600/sin 140

From this,

b/sin 21 = 600/sin 140

b/0.36 = 933.43

b = 336.03ft

Also,

a/sin 19 = 600/sin 140

a/0.33 = 933.43

a = 308.03ft

Now using ΔABD,

sin 21  =h/a

0.36 = h/308.03

h = 110.89 ft

Therefore after finding the sides of the triangle using sine law, we found that the height of the flagpole is found to be 110.89 ft.
