Answer: look below love :))

Step-by-step explanation: To find out how much Amir will have in the account after 23 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A is the final amount

P is the initial principal (the amount Amir deposited)

r is the annual interest rate (2.25%)

n is the number of times the interest is compounded per year (let's assume it is compounded annually)

t is the number of years

So, we can plug in the given values:

A = 1390(1 + 0.0225)^(1*23)

A = 1390(1.0225)^(23)

A = 1390 * 2.6388955

A = 3655.922

So Amir will have £3655.922 in the account after 23 years with 2.25% compound interest.

Answer: 40 and 50-2x.

Step-by-step explanation: you multiply 5*2=10, and subtract that from 50. You would do the same with x, to get 2*x=2x. but you can't subtract 2x from 50 without knowing x, so you leave it as 50-2x.

Answer:

To find the constant of proportionality between the cost of the game tickets and the number of tickets purchased, we can write an equation that represents the relationship between the two values. Let's call the constant of proportionality "k".

Step 1: Write an equation for Rocko's purchase:

12.50 = k * 25

Step 2: Solve for k:

k = 12.50 / 25 = 0.50

Step 3: Write an equation for Louisa's purchase:

17.50 = k * 36

Step 4: Substitute the value of k from step 2 into the equation:

17.50 = 0.50 * 36

Step 5: Check if the value of k is the same for both equations:

17.50 / 36 = 0.50

The constant of proportionality is 0.50, which means that for each additional game ticket purchased, the cost increases by $0.50.

Notes:

Answer: The table that represents blueberries that are more expensive than those represented by the equation p = 3.25b is the one where the prices listed are higher than what would be calculated using the equation p = 3.25b.

Step-by-step explanation:

To determine this, we can substitute different values of b into the equation p = 3.25b and compare the results to the prices listed in each table. For example, if b = 2 (2 pounds of blueberries), the price p would be 3.25 x 2 = 6.5 dollars, according to the equation. If any of the prices in the table is higher than 6.5 dollars for 2 pounds of blueberries, then that table represents blueberries that are more expensive than those represented by the equation p = 3.25b.

It's important to note that the equation given represents a linear equation with a slope of 3.25 and a y-intercept of 0. It's a linear equation that relates the price and weight of blueberries and can be used for any value of weight.

The solution of all the measures of the angles are,

1) m ∠A = 63°

2) m ∠B = 138°

3) m ∠C = 117°

4) m ∠D = 137.22°

Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.

In figure 1;

Measure of angle A and angle B are vertically opposite angle and hence both are equal to each other.

⇒ ∠A = ∠B

⇒ 2x + 35 = 8x - 49

⇒  35 + 49 = 8x - 2x

⇒ 84 = 6x

⇒ x = 14

Thus, The value of m ∠A = 2x + 35

                                       = 2×14 + 35

                                       = 28 + 35

                                       = 63°

2) By the figure, the sum of both indicated angle is 180°.

Hence, We get;

⇒ 10x - 18 + 15x + 48 = 180

⇒ 25x + 30 = 180

⇒ 25x = 180 - 30

⇒ 25x = 150

⇒ x = 6

Thus, The value of m ∠B = 15x + 48

                                       = 15×6 + 48

                                       = 90 + 48

                                       = 138°

3) By the figure, Both angles are alternate angle of parallel lines and hence both are equal.

So, We get;

⇒ 7x + 5= 12x - 75

⇒ 5 + 75 = 12x - 7x

⇒ 80 = 5x

⇒ x = 16

Thus, The value of m ∠C = 7x + 5

                                       = 7×16 + 5

                                       = 112 + 5

                                       = 117°

4) By the figure, the sum of both indicated angle is 180°.

Hence, We get;

⇒ 27x - 21 + 10x - 16 = 180

⇒ 37x - 37 = 180

⇒ 37x = 180 + 37

⇒ 37x = 217

⇒ x = 217/37

⇒ x = 5.86

Thus, The value of m ∠D = 27x - 21

                                       = 27×5.86 - 21

                                       = 158.22 - 21

                                       = 137.22°

Using the Pythagorean Theorem we know that the ladder can reach up to the building 85ft.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental Euclidean geometry relationship between the three sides of a right triangle.

This statement states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

So, we have:

Hypotuenese is 70ft long and Height is 25ft long.

Then, the base would be:

c² = a² + b²

70² = 25² + b²

b² = 4,900 - 625

b² = 7,275

b = √7275

b = 85ft

The probability that at least 5000 dropouts will receive the flyer is 0.7852

The probability of high school dropouts is p₀ = 20.2% or 0.202

We, know that probability is the number of favourable outcomes divided by the number of possible outcomes.

Total number of flyers sent to persons between the ages of 18 and 24 = 25000 = Total number of possible outcomes

Number of dropouts who receive the flyer = 5000 = number of favourable outcomes

Probability(p) = No. of favourable outcomes/ No. of possible outcomes

                   p = 5000/25000

                   p = 0.2

Now,

                                 z = (p - p₀)/( (p₀ (1 - p₀) ) / n)^0.5

                                 z = (0.2 - 0.202)/( (0.202 (1 - 0.202) ) / 25000)^0.5

Answer: The data shows an association between the type of instructor and a certification in CPR. The association is that swimming instructors are less likely than tennis instructors to be certified in CPR. This can be seen from the frequency table, where all the swimming instructors are not certified in CPR, while only 4 out of 12 tennis instructors are not certified in CPR, so yes, the data does show an association between the type of instructor and a certification in CPR.

Step-by-step explanation:

The two-way frequency table shows the number of instructors who are certified or not certified in CPR, broken down by type of instructor (swimming or tennis). The data in the table allows us to see the relationship between the two variables (type of instructor and certification in CPR) and whether there is an association between them.

An association means that the values of one variable are related to the values of another variable in some way. In this case, the type of instructor (swimming or tennis) is related to whether or not the instructor is certified in CPR. The data shows that the proportion of swimming instructors who are not certified in CPR (100%) is higher than the proportion of tennis instructors who are not certified in CPR (33%). This indicates that there is an association between type of instructor and certification in CPR, with swimming instructors being less likely to be certified in CPR than tennis instructors.

It is important to note that this association does not necessarily imply causation, meaning that being a swimming instructor does not cause one to not be certified in CPR, but it could be the other way around, or it could be due to some other factors that the data does not show.
