Step-by-step explanation:

The value of x is obtained as follows:

128º.

The measure of angle A is given as follows:

m < A = 132º.

For a parallelogram, the opposite angles are congruent, meaning that they have the same measure, hence the value of x is obtained as follows:

5x - 508 = x + 4.

4x = 512

x = 512/4

x = 128.

Then the measure of angle A is given as follows:

m < A = 5(128) - 508

m < A = 132º.

The length of the diagonal is 12.6 feet.

"Information available from the question"

The perimeter of a rectangle is 32 feet.

The length is three times as long as the width.

We have to find the length of the diagonal.

Let w = width

then

3w = length.

Because we know the perimeter:

Perimeter of the rectangle is : 2(l + w)

32 = 2(w + 3w)

32 = 2(4w)

16 = 4w

4 feet = w (width)

Length:

3w = 3(4) = 12 feet

Diagonal, we use the Pythagorean theorem:

Let d = diagonal

then,

[tex]d^2 = 4^2 + 12^2[/tex]

[tex]d^2[/tex] = 16 + 144

[tex]d^2[/tex] = 160

d = 12.6 feet

The water's height at 8:30 PM is approximately 0.69 feet.

As per the data given in the question,

We have the equation,

depth = 4 * sin (0.5 * t)

where t is the number of hours after midnight.

As we need to find the depth of the water at 8:30 PM,

For finding the value of the depth at 8:30 PM we need to first convert 8:30 PM to the number of hours after midnight.

8:30 PM = 20.5 hours after midnight

So, substituting t = 20.5 into the equation,

we will get it as:

depth = 4 * sin (0.5 * 20.5)

depth = 4 * sin (10.25)

depth = 4 * 0.1736481776669303

depth = 0.6945971520676809

The solution to the given inequality  [tex]-5f + 6 > 10f - 10[/tex] is [tex]f < 16/15[/tex].

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The inequality is given in the question, as follows:

[tex]-5f + 6 > 10f - 10[/tex]

To solve the inequality [tex]-5f + 6 > 10f - 10[/tex], we need to isolate the variable [tex]f[/tex] on one side of the inequality.

We will first subtract 6 from both sides to isolate the [tex]-5f[/tex] term:

[tex]-5f + 6 - 6 > 10f - 10 - 6[/tex]

Simplifying the left side:

[tex]-5f > 10f - 16[/tex]

Next, we will subtract [tex]4f[/tex] from both sides to isolate the [tex]-5f[/tex] term on the left side:

[tex]-5f - 10f > 10f - 10f - 16\\-15f > -16[/tex]

Finally, we will divide both sides by -9,

[tex]-( 15 f )/9 > -16/15[/tex]

Dividing both sides by -15:

[tex]f < 16/15[/tex]

Answer:

(-2,2)

Step-by-step explanation:

First, let's look at the 2 inequalities:

y ≤ -x + 1

y > x

Just by looking at the second inequality, we can remove any ordered pairs where x is greater than or equal to y. This eliminated the ordered pairs (-1,-3) and (0,-1). Now, the answer has to be (-3,5) or (-2,2). Knowing this, we can plug x and y into the equation and see if either of the answers are true.

(-3,5):

x = -3

y = 5

y ≤ -x + 1

5 ≤ -(-3) + 1

5 ≤ 3 + 1

5 ≤ 4

NOT TRUE

(-2,2)

x = -2

y = 2

2 ≤ -(-2) + 1

2 ≤ 2 + 1

2 ≤ 3

TRUE

So, since plugging in the ordered pair (-2,2) into the inequality gives us a true answer while (-3,5) doesn't, the order pair (-2,2) must be out answer.

Graph 3

How to choose the correct graph?

Before choosing the correct graph, we must classify the function as discrete or continuous, as follows:

Discrete function: the input values of the function are only certain values on an interval.

Continuous function: the input values of the function are all the real values in the interval.

Then the graph of each type of function is given as follows:

Discrete function: dots.

Continuous function: solid line.

The input and output variables in this problem are given as follows:

Input variable: number of chapters.

Output variable: number of pages.

The number of chapters assumes only integer values, hence the function has a discrete domain, meaning that the graph is composed by dots.

However, the first graph is correct, as the third graph has a range of input and output values that is not present on the table, while the range in the first graph is according to the table.

The same attribute is expressed using a unit conversion, but in a different unit of measurement.

For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

Ms. Winn bought = 3/5 lb of grapes

Ms Winn bought = 5/8 lb of cherries.

As, there are 16 ounces in a pound then

= 3 pounds/4 x 16 ounces/pound

= 3 x 4

The correlation between the two variables in the data set for 13 colonies of sparrowhawks is 0.5602.

This means that there is a moderate positive correlation between the two variables, indicating that when one variable increases, the other variable is likely to increase as well.

To calculate the correlation coefficient, we can use Pearson’s correlation coefficient equation:

r = (n * Σxiyi - Σxi * Σyi) / √[(n * Σxi2 - (Σxi)2) * (n * Σyi2 - (Σyi)2)]

Where: n = the number of observations Σxi = the sum of all x-values Σyi = the sum of all y-values Σxiyi = the sum of the products of each x-value and y-value Σxi2 = the sum of the squares of each x-value Σyi2 = the sum of the squares of each y-value

Plugging in the values for our data set, we get:

r = (13 * 0.5602 - (13 * 0.5602)) / √[(13 * 0.2532 - (13)2) * (13 * 0.2532 - (13)2)]

r = 0.5602

The variable b in terms of the variables a and c is b = ac/(a - c)

From the given formula expressed as

1/a + 1/b = 1/c

We want to express variable b in terms of the variables a and c. We would make variable b the subject of the formula.

Subtracting 1/a from the left hand side of the equation and the right hand side of the equation, it becomes

1/a - 1/a + 1/b = 1/c - 1/a

1/b = 1/c - 1/a

1/b = (a - c)/ac

Answer:

assuming that it can be solved, then yes

Step-by-step explanation:

So, approximately 2.28% of the observations are less than 140.

To find the percentage of observations that are less than 140, we need to find the standard score (z-score) that corresponds to 140, and then use a standard normal table to find the proportion of data that is less than that z-score.

The standard score is calculated as follows:

z = (140 - 130) / 5 = 2

Using a standard normal table, we can find the proportion of data that is less than 2 standard deviations from the mean. This proportion is approximately 0.0228 or 2.28%.

Mean is nothing but the average of data.

What are exterior angles ?
An exterior angle is an angle which is formed by one of the sides of any closed shape structure such as polygon and the extension of its adjacent side.

Given:

Interior angles : (a+10)° and 44°

Thus , we know that

Exterior angle  = sum of interior opposite angles

Therefore , Exterior angle  = (a+10)° + 44°

or

2a° = (a+10)° + 44°
