Answer:

p = 6

Step-by-step explanation:

The value of the investment modeled by the function V(t) = 50(0.9)^t Decreases at a decreasing rate, starting with an initial value of 50.

We are given the investment value function V(t) = 50(0.9)^t. This function describes the value of an investment over time, t. Let's analyze the behavior of V(t) and find a statement that is supported by this function.

1. The initial value of the investment is V(0) = 50(0.9)^0 = 50(1) = 50. So, the investment starts with a value of 50.

2. The function V(t) contains a term (0.9)^t, which indicates that as time passes, the investment value decreases. This is because 0.9 is between 0 and 1, so raising it to a power of t (as t increases) results in a smaller value.

3. The rate of decrease is not constant, as the function is exponential, not linear. This means the value of the investment decreases at a decreasing rate over time.

Based on the behavior of V(t), the following statement is supported:

As time passes, the value of the investment modeled by the function V(t) = 50(0.9)^t decreases at a decreasing rate, starting with an initial value of 50.

That statement that best describes the relationship between x and y in the given equations is: d. In y = 25x, the value of y is 25 times the value of x, and in y = x + 25, the value of y is 25 more than the value of x.

In the equation y = 25x, the value of y is directly proportional to x and is 25 times greater than x. This means that as x increases, y increases by a multiple of 25. For example, if x = 2, then y = 50 (25 x 2), and if x = 4, then y = 100 (25 x 4).

In the equation y = x + 25, the value of y is equal to the value of x plus 25. This means that y is always 25 greater than x, regardless of the value of x. For example, if x = 2, then y = 27 (2 + 25), and if x = 4, then y = 29 (4 + 25).

The answer is option d.

The probability of getting someone who tested positive, given that he or she had the disease, is 0.9.

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

The probability of getting someone who tested positive, given that he or she had the disease, is equal to the probability that the individual has the disease and tests positive ( P(positive | disease) ).

This can be calculated using the formula P(A|B) = P(A∩B) / P(B)

P(positive | disease) = P(positive ∩ disease) / P(disease)

                    = 141 / (141+16)

                    = 0.898

Answer:

CF =  12
DE  = 23
CD =  23
DF = 23.9

Step-by-step explanation:

We can see that there are 2 right-angled triangles: DEF and CDF with common side FD.

They are right angled triangles because the EF and CF are radii of the circle and these segments intersect the tangents at 90°

The common side DF is the hypotenuse for both triangles

The sides EF and CF are radii of the circle so EF = CF

We have two triangles which have two sides equal and one of the angles equal to the corresponding angle of the other

By the SSA theorem, the two triangles are similar

SSA Theorem

if two sides and an angle not included between them are respectively equal to two sides and an angle of the other then the two triangles are equal

Therefore by the law of similar triangles,

CD  = EF

Plugging in the expressions we get
13x - 16 = 4x + 11

Subtract 4x from both sides:
13x - 4x - 16 = 11
9x - 16 = 11

Add 16 to both sides:
9x - 16 + 16 = 11 + 16

9x = 27

x = 27/9 = 3

Therefore
ED = 4x + 11 = 4(3) + 11 = 12 + 11 = 23

and this is equal to CD

Using the Pythagorean theorem for right triangles,

For ΔDEF,

DF² = EF² + DE²

DF² = 12² + 23²

= 144 + 529

= 673

DF = √673

= 25.9422

= 25.9 rounded to the nearest tenth

So the measures of the segments are
CF = 12
DE = 23
CD = 23
DF = 23.9

The total contribution to Sharon's account over the 25-year period is $64,800.

To find the total contribution to Sharon's account, we need to consider both her contribution and her employer's contribution.

Social Security taxes are generally split evenly between the employee and the employer, with each paying half of the tax.

Sharon paid $32,400 in Social Security taxes over the 25-year period, which represents her share (half) of the total Social Security taxes paid.

To find the total contribution to her account, we simply need to double her share to include the employer's contribution:

Total contribution = Sharon's contribution + Employer's contribution

Total contribution = $32,400 + $32,400

Total contribution = $64,800

The total contribution to Sharon's account over the 25-year period is $64,800.

Answer: A. Nikko by 2 inches

The area of the region bounded by the curves y = x² + 6x + 9 and y = 4 is 16  ² / ₃ square units.

First, we need to find the points of intersection between the two curves. Set y = x² + 6x + 9 equal to y = 4:

x² + 6x + 9 = 4

Now, solve for x:

x² + 6x + 5 = 0

Factor the quadratic equation:

(x + 5)(x + 1) = 0

This gives us the solutions x = -5 and x = -1. These are the x-coordinates of the points of intersection.

Now, to find the area of the region bounded by the curves, we'll integrate the difference between the two functions with respect to x, from x = -5 to x = -1:

Area = ∫[4 - (x² + 6x + 9)]dx from -5 to -1

Area = ∫[5 - x² - 6x]dx from -5 to -1

Now, integrate:

Area = [5x - (x³/3) - 3x²] from -5 to -1

Plug in the limits:

Area = (5(-1) - (-1)³/3 - 3(-1)²) - (5(-5) - (-5)³/3 - 3(-5)²)

Area = (-5 - 1/3 - 3) - (-25 + 125/3 - 75)

P = principal amount

r = annual interest rate

n = the number of times interest is to be compounded per year

t = time in years

In this case, we have:

-1.96 and 1.96 are the essential z values for a two-tailed test with a significance level of 0.05.

A null hypothesis is a statistical hypothesis that presupposes that there is no link between two variables in a population or that there is no meaningful difference between two populations. It serves as the beginning point of a statistical hypothesis test and is typically marked as H0. A null hypothesis serves as a reference point against which the alternative hypothesis may be compared. The alternative hypothesis is accepted if there is sufficient evidence from the data to reject the null hypothesis. The null hypothesis is not rejected if there is insufficient evidence in the data to support it.

Using a significance threshold of 0.05, we may use a conventional normal distribution table or calculator to get the essential z value. The value that corresponds to the 0.025 percentile is the crucial z value (or the 0.975 percentile, depending on the direction of the alternative hypothesis).

The z value for the 0.025 percentile, as determined by a typical normal distribution table, is -1.96.

Simplify

7x = y + 16

Multiply by 2

14x = 2y + 32

Subtract from 5x = 2y + 5
