Step-by-step explanation:

The amplitude is the value that the cosine is being multiplied by.

The general equation of a sinusoid is

\( a \cos(b(x + c) ) + d\)

where a is the amplitude

\( \frac{2\pi}{ |b| } \)

is the period

-c is the phase shift

d is the midline(vertical shift)

Here the amplitude is -1/2 so b is the correct answer.

Answer:

1. The first figure posses the SSS property.

2. The second figure posses the ASA property.

3. The third figure posses the hypotenuse length property.

4. The fourth figure posses the SAS property.

Given:

1. The first figure shows the SSS property.

Side-Side-Side criterion is referred to as the SSS criterion. According to this standard, two triangles are congruent if their respective triangles' three sides are equal to one another.

hence the two triangles are congruent.

2. The second figure posses the ASA property.

Angle-Side-Angle criterion is also known as ASA criterion. According to the ASA criterion, two triangles are congruent if any two of their included sides and related angles are equivalent in size to those of the other triangle.

hence the two triangles are congruent.

3. The third figure posses the hypotenuse length properety.

RHS criterion stands for right angle-hypotenuse-side congruence criterion. Under this criterion, two triangles are congruent, if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle.

hence the two triangles are congruent.

4. The fourth figure posses the SAS property.

Side-Angle-Side criterion is referred to as the SAS criterion. According to this standard, two triangles are said to be congruent if their matching sides and included angles are the same on each side of each other.

hence the two triangles are congruent.

Hence we get the required answer.

Edna should leave at 2:07 PM in order to arrive at Jake's party by 2:30 PM

To determine the time Edna should leave, we need to subtract the travel time from the desired arrival time.

If Edna needs to be at Jake's party at 2:30 PM and it takes her 23 minutes to drive there, she should leave 23 minutes before 2:30 PM.

To calculate the departure time, we subtract 23 minutes from 2:30 PM:

2:30 PM - 23 minutes = 2:07 PM

Therefore, Edna should leave at 2:07 PM in order to arrive at Jake's party by 2:30 PM

Answer: 1. 6.1

2. 13

3. 5.4

4. 5.7

5. 10.4

6. 31

Step-by-step explanation:

I got the values of the missing sides by doing the Pythagorean theoreom. Therefore, I had to find the length of the hypotenuse. a^2+b^2=c^2

a and b are the values of the sides given, and we have to find the value of c. So, for instance on number one 6 and 3 are a b. (6)^2+(3)^2= 45. Now we have to find the square root of 45. The square root of 45 is 6.7082039325.

So the value of the missing side in number one is 6.7.

The best predicted systolic blood pressure in the left arm, when the systolic blood pressure in the right arm is 80 mm Hg, is approximately 153.7 mm Hg.

In order to find the regression equation and predict the systolic blood pressure in the left arm based on the systolic blood pressure in the right arm, we will perform linear regression analysis. This statistical technique helps us understand the relationship between two variables and make predictions based on that relationship. In this case, the predictor variable (x) is the systolic blood pressure in the right arm, and the response variable (y) is the systolic blood pressure in the left arm.

To find the regression equation, we need to determine the slope (β₁) and intercept (β₀) of the line that best fits the data points. The equation for simple linear regression is given by:

y = β₀ + β₁x

where y represents the response variable (systolic blood pressure in the left arm), x represents the predictor variable (systolic blood pressure in the right arm), β₀ is the intercept, and β₁ is the slope.

To calculate the regression equation, we can use statistical software or perform the calculations manually using the least squares method. Let's calculate the slope and intercept:

Step 1: Calculate the means of x and y, denoted as x' and y', respectively.

x' = (103 + 102 + 94 + 75 + 74) / 5

   = 88

y' = (177 + 170 + 146 + 143 + 144) / 5

   = 156

Step 2: Calculate the differences between each x value and x' (denoted as Δx) and each y value and y' (denoted as Δy).

Δx = [103 - 88, 102 - 88, 94 - 88, 75 - 88, 74 - 88]

    = [15, 14, 6, -13, -14]

Δy = [177 - 156, 170 - 156, 146 - 156, 143 - 156, 144 - 156]

    = [21, 14, -10, -13, -12]

Step 3: Calculate the sum of the products of Δx and Δy, denoted as Σ(Δx * Δy), and the sum of the squared differences of x, denoted as Σ(Δx^2).

Σ(Δx * Δy) = (15 * 21) + (14 * 14) + (6 * -10) + (-13 * -13) + (-14 * -12)

                = 315 + 196 - 60 + 169 + 168

                = 788

Σ(Δx²) = 15² + 14² + 6² + (-13)² + (-14)²

          = 225 + 196 + 36 + 169 + 196

          = 822

Step 4: Calculate the slope (β₁) using the formula:

β₁ = Σ(Δx * Δy) / Σ(Δx²)

    = 788 / 822

    ≈ 0.958

Step 5: Calculate the intercept (β₀) using the formula:

β₀ = y' - β₁x'

    = 156 - (0.958 * 88)

     ≈ 74.984

Therefore, the regression equation is y = 74.984 + 0.958x, rounded to one decimal place.

To predict the systolic blood pressure in the left arm given that the systolic blood pressure in the right arm is 80 mm Hg, we can substitute x = 80 into the regression equation and solve for y:

y = 74.984 + 0.958(80)

  ≈ 153.704

Hence, the best predicted systolic blood pressure in the left arm, when the systolic blood pressure in the right arm is 80 mm Hg, is approximately 153.7 mm Hg, rounded to one decimal place.

The proportion of a normal distribution that is located in the tail when z = 1.50 is 0.0668. So, the correct option is a.

Here's how to solve the problem:

We are given that z = 1.50.

To find the proportion of a normal distribution that is located in the tail when z = 1.50, we need to use a standard normal distribution table (also known as a z-score table). The table provides the area under the standard normal distribution curve to the left of a given z-score.

Since z = 1.50 is positive, we are interested in the area in the right tail of the standard normal distribution curve. The standard normal distribution table provides the area to the left of a given z-score. Therefore, to find the area in the right tail, we subtract the area in the left tail from 1 (the total area under the curve).

Using the standard normal distribution table, we find that the area to the left of z = 1.50 is 0.9332. Therefore, the area to the right of z = 1.50 (in the right tail) is: 1 - 0.9332 = 0.0668

Thus, the proportion of a normal distribution that is located in the tail when z = 1.50 is 0.0668, which is option (a).

if the tax bill is 35% and the trend from year 1 to year 2 continues into year 3, the tax bill in year 3 would be approximately X * 1.8225 million dollars.

To calculate the tax bill in year 3, we first need to understand the trend from year 1 to year 2.

Since you haven't provided specific data, I'll assume that the trend implies a constant percentage increase in the tax bill each year.

Let's assume that in year 1, the tax bill was X million dollars. If the tax bill increases by the same percentage from year 1 to year 2, we can calculate the tax bill in year 2 by multiplying X by 1 plus the tax increase percentage.

In this case, the tax increase percentage is 35%, so the tax bill in year 2 would be X * (1 + 0.35) = X * 1.35 million dollars.

If the trend continues into year 3, we apply the same logic. The tax bill in year 3 would be the tax bill in year 2 multiplied by 1 plus the tax increase percentage: (X * 1.35) * (1 + 0.35) = X * 1.35 * 1.35 million dollars.

Answer:

Her average speed is 45 mph

Step-by-step explanation:

Let the average speed be x mph

Time taken complete the journey = distance/ average speed

Time = 300/x

Now , at 9 mph less, she could have only traveled 240 miles in same time

At 9 mph less, the average speed is x-9

so the time would be 240/x-9

since the time is same as before;

300/x = 240/x-9

Divide both sides by 60

5/x = 4/x-9

Cross multiply

5(x-9) = 4(x)

5x - 45 = 4x

5x -4x = 45

x = 45 mph

Now move the 2.8 and 2.5x so..

1.8x - 2.5x=2.1 - 2.8 also switch the operation from addition to subtraciton.

Now subtract 1.8x to 2.5x which is -0.7x

Your new equation should look like this---> -0.7x=2.1 - 2.8

Now subtract 2.1 to 2.8

which is -0.7

So now your equcation should look like this--> -0.7 = -0.7

Now multiply both the -0.7 to 10 so

-0.7 · 10= -7

Now your equation is -7x = -7 now divide both sides by -7

which is 1

so x=1 which is only one solution so

A plane cannot be named by any three points in the plane because there are infinitely many planes that can pass through those points. By specifying only three points, we do not have enough information to uniquely identify a single plane.

To uniquely define a plane, we need to use three noncollinear points. Noncollinear points are points that do not lie on the same line. By choosing three noncollinear points, we can determine a unique plane that passes through those points. The combination of these three points creates a plane that is different from any other plane passing through any other set of three noncollinear points.

In summary, naming a plane requires three noncollinear points because this combination uniquely identifies a plane, whereas three points alone are not sufficient for this purpose.
