Answer:

The solution of the mathematical expressions will be 0.175.

Step-by-step explanation:

Given that;

The mathematical expressions are,

⇒ [ 2 - | - 1/4 - 2 (-3/5) | ] ÷ -6

Now,

Solve the mathematical expression as;

⇒  [ 2 - | - 1/4 - 2 (-3/5) | ] ÷ -6

Using the BODMAS rule to solve the expressions as;

⇒ [ 2 - | - 1/4 - 2 (-3/5) | ] ÷ -6

⇒ [ 2 - | - 1/4 + 6/5 | ÷ -6

⇒ [ 2 - 19/20 ] ÷ -6

⇒  [ 21/20] ÷ -6

⇒ 21/20 x 1/-6

⇒ - 7 / 40

Therefore,

The solution of the mathematical expressions will be 0.175.

[tex]-\dfrac{7}{40}[/tex]

Step-by-step explanation:

Given expression:

[tex]\left[2-\left|-\dfrac{1}{4}-2\left(-\dfrac{3}{5}\right)\right|\right] \div (-6)[/tex]

Carry out the operations inside the absolute value bars (following the order of operations):

[tex]\implies \left[2-\left|-\dfrac{1}{4}+\dfrac{6}{5}\right|\right] \div (-6)[/tex]

[tex]\implies \left[2-\left|\dfrac{19}{20}\right|\right] \div (-6)[/tex]

As the fraction inside the absolute value bars is already positive, we can simply remove the bars:

[tex]\implies \left[2-\dfrac{19}{20}\right] \div (-6)[/tex]

Rewrite 2 as 40/20 and carry out the subtraction inside the square brackets:

[tex]\implies \left[\dfrac{40}{20}-\dfrac{19}{20}\right] \div (-6)[/tex]

[tex]\implies \left[\dfrac{40-19}{20}\right] \div (-6)[/tex]

[tex]\implies \left[\dfrac{21}{20}\right] \div (-6)[/tex]

Rewrite -6 as a fraction:

[tex]\implies \dfrac{21}{20} \div -\dfrac{6}{1}[/tex]

When dividing fractions, multiply the first fraction by the reciprocal of the  second fraction:

[tex]\implies \dfrac{21}{20} \times-\dfrac{1}{6}[/tex]

[tex]\implies \dfrac{21 \times (-1)}{20 \times 6}[/tex]

[tex]\implies -\dfrac{21}{120}[/tex]

Reduce the fraction to its simplest form by dividing the numerator and denominator by the highest common factor, 3:

[tex]\implies -\dfrac{21 \div 3}{120 \div 3}[/tex]

[tex]\implies -\dfrac{7}{40}[/tex]

Answer:

yes to all 3

Step-by-step explanation:

A

3z = 21 ( isolate z by dividing both sides by 3 )

z = 7

B

n + 14 = 36 ( subtract 14 from both sides )

n = 22

C

[tex]\frac{3}{4}[/tex] v = 12 ( multiply both sides by 4 to clear the fraction )

3v = 48 ( divide both sides by 3 )

v = 16

Step-by-step explanation:

The equation of the line in point-slope form is obtained as y = (5/4)x - 20.

What is the point-slope form?

Point-slope is the general form of a linear equation which is y-y1=m(x-x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).

The line passes through point (x1,y1) = (-8,-7)

The slope of the line is m = 5/4.

The formula for point-slope form of equation is -

y-y1=m(x-x1)

Substituting the values in the equation -

y - (-7) = 5/4[x - (-8)]

y + 7 = 5/4 (x + 8)

4(y + 7) = 5(x + 8)

4y + 28 = 5x + 8

4y - 5x = 8 - 28

4y - 5x = -20

4y = 5x -20

y = (5/4)x - 20

Therefore, the equation is obtained as y = (5/4)x - 20.

What is the right triangle?

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle, i.e. two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle.

Given that the angles of a triangle are 30-60-90.

The smallest angle is always opposite the shortest side, and vice versa. The longest side is also opposite the largest angle, and vice versa.

The opposite side of angle 30 is the shortest side of the triangle.

The opposite side of angle 90 is the longest side of the triangle.

Sine law:

a/sin A = b/ sin B =c/sin C

a is the opposite side of angle A, b is the opposite side of angle B, c is the opposite side of angle C.

Assume that the length of the longest side is a.

Applying sine law in the given triangle:

6√10/sin 30 = a/sin 90

In geometry, each triangle has a few highly significant points that go along with it. One such point is the triangle's orthocenter, which is identified as the location where the triangle's altitudes cross.

An altitude of a triangle is a line segment that extends perpendicularly from one of its vertices to the side opposite that vertex. A triangle with an angle larger than 90° is said to have an obtuse angle. The heights of the vertices of the acute angles of an obtuse triangle reside outside of the triangle due to the way the triangle is constructed.

The orthocenter, or the location where the three elevations intersect, must therefore be outside of the circumcircle in which the triangle is inscribed.

The domain of this relationship would be all possible combinations of values for x and y that satisfy the equation 5x + 9y = 90.

To find the equation:

The domain of the relationship in this scenario is the number of youth and adult tickets that were purchased by the group.

It is given that the cost of a youth ticket is $5 and the cost of an adult ticket is $9. Therefore, the number of youth and adult tickets can be represented by the variables x and y respectively.

We also know that the group spent a total of $90 on tickets, so the equation representing the relationship between the number of youth and adult tickets purchased would be:

5x + 9y = 90

So the domain of this relationship would be all possible combinations of values for x and y that satisfy the equation 5x + 9y = 90.

It's important to note that the domain would be all non-negative integers of x and y as the number of youth and adult tickets cannot be negative numbers.

The area of the rectangle ABEF = 2sa = 2ss/(2*tan(180/8)) = s^2/(tan(180/8)).

What is an octagon?

An octagon is a polygon with eight straight sides and eight angles. It is a closed two-dimensional shape with eight sides of equal length. A regular octagon is an octagon in which all sides and angles are equal.

When it comes to the area of a regular octagon, the area of a regular polygon can be calculated using the formula

A = (ns^2)/(4tan(180/n)) where A is the area, n is the number of sides and s is the length of each side.

In case of a regular octagon, the area of an octagon is (8s^2)/(4tan(180/8))

A rectangle ABEF is made up of two congruent sides with the length of the side of the octagon, and two congruent sides with the length of the apothem of the octagon.

An apothem of a regular polygon is the distance from the center of the polygon to the midpoint of any side. The apothem of a regular octagon can be calculated by using the formula

a = s/(2*tan(180/8)) where a is the apothem and s is the side of the octagon.

Hence, the area of the rectangle ABEF = 2sa = 2ss/(2*tan(180/8)) = s^2/(tan(180/8)).

A line graph is marked by a correlation in the form of a line. The dependent variable is placed on the y-axis and the independent variable is on the x-axis.

You can see their relationship in terms of the slope. By explanation, the slope is the ratio of the change of the y-coordinates to the change of the x-coordinates (Δy/Δx). Visually, you determine the relationship of the variables by the orientation of the line as shown in the graph. If the slope is increasing, means that the two variables are increasing together.

If the slope is decreasing, it means that when x increases, y decreases. In other words, they are inversely proportional.

Compared to a 95% confidence interval, a 99% confidence interval will be wider.

A confidence interval is a range of values that is likely to contain the true population mean, with a certain level of confidence.

The level of confidence is usually represented as a percentage, such as 95% or 99%. The higher the level of confidence, the wider the confidence interval will be. This is because a higher level of confidence means that the researcher wants to be more certain that the true population mean falls within the interval, so they will make the interval wider to increase the chances of this happening.

Answer: Vera's starting salary at the company was $53600.

Step-by-step explanation:

We can start by using the following proportion:

(Current salary) / (Starting salary) = (Percent increase) / 100

So we can write:

67,000 / Starting salary = 125 / 100

To find the starting salary we can cross-multiply and divide:

67,000 = (125 * Starting salary) / 100

67,000 * 100 = 125 * Starting salary

67,000 * 100 = 125 * Starting salary

67,000,000 = 125 * Starting salary

Starting salary = 67,000,000 / 125

Step-by-step explanation:

for washing 10 houses we get (14*10) dollars which is 140

now for washing cars ur frirnd gets (28*5) which is also 140

so u both earn the same amount

hence the answer is neither.

The probability of getting exactly 8 girls out of 11 births is 21.9%.

The binomial probability formula is used to calculate the probability of getting a certain number of successes (in this case, girls) out of a fixed number of trials (in this case, 11 births).

The first part of the formula (11 choose 8) is the number of ways to choose 8 girls out of 11 births, which is 330.

i.e;    (11 choose 8) * (0.5)^8 * (0.5)^3 = 330

The second part of the formula (0.5)^8 represents the probability of getting 8 girls out of 11 births assuming each birth has a probability of 0.5 of being a girl.

The third part of the formula (0.5)^3 represents the probability of getting 3 boys out of 11 births assuming each birth has a probability of 0.5 of being a boy.

i.e; (11 choose 8) * (0.5)^8 * (0.5)^3 = 330 * 0.00390625 * 0.125 = 0.21875

When we multiply all of these values together we get the final probability of getting exactly 8 girls out of 11 births, which is approximately 0.21875 or about 21.9%.

Therefore, the probability of getting exactly 8 girls out of 11 births is given by the binomial probability formula: (11 choose 8) * (0.5)^8 * (0.5)^3 = 330 * 0.00390625 * 0.125 = 0.21875 or about 21.9%.
