pls help worth b and c “find the slope of each line”

Answer:

.25

Step-by-step explanation:

there are 4 quarts in a gallon so 1 quart is 1/4 of that so its .25

Answer:

To calculate the percent change of two numbers, such as 25 to 30, you use the Percent Change Formula, where a is the start value and b is the end value.

(b - a)/a × 100

When we insert a = 25 and b = 30 in the formula above, then we get the following that we can simplify and solve to get the percent change from 25 to 30.

(30 - 25)/25 × 100

5/25 × 100

Change = 20%

Step-by-step explanation:

The correlation coefficient of 0.90 indicates the strongest linear relationship between two variables. It means that there is a strong positive or negative linear relationship between the two variables.

The correlation coefficient is calculated by finding the covariance of two variables, divided by the product of their standard deviations. The formula is as follows:

Coefficient = Covariance(X,Y) / (Standard Deviation of X * Standard Deviation of Y)

For example, if X and Y have a covariance of 6 and standard deviations of 2 and 3 respectively, then the correlation coefficient is:

Coefficient

= 6 / (2 * 3)

= 0.90

The correlation coefficients indicates the strongest relationship between two variables is 0.90

The term correlation coefficient in math is defined as the strength of association between two variables.

Here we need to identify the correlation coefficients indicates the strongest relationship between two variables.

As  we all know that the value of a correlation coefficient ranges between -1 and 1 and here we also know that the strongest linear relationship is indicated by a correlation coefficient of -1 or 1.

Here the weakest linear relationship is indicated by a correlation coefficient equal to 0.

If there is a positive correlation means that if one variable gets bigger, then the other variable tends to get bigger where as in a negative correlation means that if one variable gets bigger, then the other variable tends to get smaller.

Based on these definition, we have identified that option (b) is correct.

Answer:

89°

Step-by-step explanation:

The sum of the interior angles of any quadrilateral is 360°

So,

360° - 154° - 88° - 29°

= 89°

Answer:

x = 89

Step-by-step explanation:

The interior angles of a quadrilateral sum to 360°.

Therefore:

⇒ 88° + 154° + 29° + x° = 360°

⇒ 271° + x° = 360°

⇒ 271° + x° - 271° = 360° - 271°

⇒ x° = 89°

⇒ x = 89

It's worth noting that some people might consider a month to be complete after a certain number of days have passed, such as 30 days or 31 days.

What is the time and date calculations?

Time and date calculations involve mathematical operations to determine the difference between two dates, calculate the number of days, weeks, months, or years between two dates, and perform other similar operations with dates and times.

To calculate the 9th month from the date that you got back together with someone on January 30th, we need to consider the fact that not all months have 30 days and that February has 28 days in a non-leap year.

One method to keep track of the months would be to use the calendar to add the number of months to the starting date and adjust for any changes in the year or the month.

Starting from January 30th, we add 8 months to get September 30th. Adding one more month will take us to October 30th, which is the 9th month from the starting date.

Pythagoras Theorem says that, for a triangle which is right, the sum of the squares of base and altitude is equal to the square of hypotenuse.

Here if a person travels north and other person travels east, there forms a right triangle by connecting the end points of the position of two persons.

We have to find hypotenuse.

Base = 9 meters and Altitude = 12 meters

Hypotenuse² = Base² + Altitude²

                      = 9² + 12²

                      = 81 + 144

The association becomes weaker as it approaches zero. The stronger it is, the closer it is to +/-1.

An analysis of two variables' relationships using statistics is called a correlation. 2 Keep in mind the simple rule that the connection is weaker the closer it is to 0. The stronger it is, the closer it is to +/-1.

When the correlation coefficient is zero or almost zero, there is no discernible relationship between the variables. In a perfect correlation, where a change in one variable accurately predicts changes in the other, the coefficient is either 1.0 or -1.0.

Always a value between -1 and 1, r. r > 0 denotes a favourable connection. A negative connection is indicated by r 0. A extremely weak linear relationship is shown by r values close to 0.

Step-by-step explanation:

you understand how exponents work, right ?

an exponent defines how often its base has to be multiplied by itself.

so,

(-1 + 3i)⁵

means that

(-1 + 3i)

is multiplied 5 times by itself.

and that means we can split this into sub-multiplication groups like

(-1 + 3i)²×(-1 + 3i)²×(-1 + 3i) = (-1 + 3i)⁴×(-1 + 3i)

the advantage is that squares are easily calculated.

(a + b)² = a² + 2ab + b²

so,

(-1 + 3i)² = (-1)² + 2×-1×3i + (3i)² = 1 - 6i - 9 = -8 - 6i

(-1 + 3i)²×(-1 + 3i)² = ((-1 + 3i)²)² = (-8 - 6i)² =

= (-8)² + 2×-8×-6i + (-6i)² = 64 + 96i - 36 = 28 + 96i

(-1 + 3i)⁵ = (28 + 96i)(-1 + 3i) = -28 + 84i - 96i - 288 =

Answer: Yes there proportional:)

Step-by-step explanation:

The diameter of a circle is twice the length of the radius, so if the diameter of a circle is proportional to the radius, then the diameter will be equal to twice the radius.

The ratio of the radius of the circle with a diameter of 100 mm to the radius of the circle with a diameter of 10 mm is 50 mm / 5 mm = 10.

The ratio of the diameters of the two circles is 100 mm / 10 mm = 10.

Since the ratio of the radius to the diameter is the same for both circles, the radius and diameter of both circles are proportional.

How will you identify a "single variable equation"?

A variable serves as a predetermined placeholder for an unknown integer. Math problems frequently employ the variables X and Y, although variables can also be represented by any other symbol or letter.

Two mathematical expressions are equalized using an equation. Depending on the expression, the terms on either side might be as straightforward as a single integer or as complicated as an expression with several variables, exponents, or other components. This equivalence may be expressed by using the equals symbol (=).

This kind of equation only has one variable and is referred to as a single variable equation. The possibility of using the variable more than once or on both sides of the equation must be kept in mind.
