Determine whether the statement is true or false. If false, give a counterexample.
The constant of proportionality in an equation can never be 0.

Answer:

1.50x < 12 (the inequality would just be "less than")

Step-by-step explanation:

Except Option - A all satisfy the more appropriate measures of center and spread for the data that is median and IQR.

Given that,

We have to find what are the more appropriate measures of center and spread for data.

We know that,

Mean, median, and mode are the three central tendencies, and median is the more accurate indicator.

This is because

i) Extreme values affect the mean.

ii) If there are more outliers, the mean is in error.

iii) Means that are biassed to the right or left may not accurately reflect the nature of the data.

However, median is preferable to mean because it represents the center entry and is unaffected by extreme items or outliers.

Since extreme items will show higher standard deviation and some outliers may be misleading, IQR is a superior spread measurement tool. However, IQR provides an excellent idea.

Answer:

x² - 6x = -5

x = {1, 5}

Step-by-step explanation:

The square of a number minus six times a number equals negative five.

x² - 6x = -5

Answer:

A B and D

Step-by-step explanation:

Given the parabola is opening downward, the function has to be negative. Therefore, A B and D are correct.

The following equations could define the given quadratic function.

1. -1(x-1)²+9

4. -x²+2x+8

6. (x+2)(x-4)

A parabola is a U-shaped curve this is drawn for a quadratic function,

f(x) = ax² + b x + c.

1. The function -1(x-1)²+9 represents a downward-facing parabola.

The vertex of the parabola is at point (1, 9), and it opens downward because the coefficient of the squared term (-1) is negative.

4. The function -x²+2x+8 represents a downward-facing parabola as well.

6. The parabola intersects the x-axis at x = -2 and x = 4.

Hence, the correct answer is options 1, 4, 6.

The constant of proportionality is 10 for the proportional relationship shown in the graph.

The constant of proportionality is the constant value of the ratio of two proportional values. A proportionality relation exists between two changing quantities when either their ratio or product gives a constant.

The proportional relationship is shown in the given graph.

As per the given graph, we take two points (1, 10) and (2, 20)

So, the constant of proportionality will be as:

⇒ (20 - 10)/(2-1)

⇒ 10/1

⇒ 10

If you buy a sweater, the second one is at 40% discount.

Divide the discount between the two to get:

You get a discount of 20% for each sweater.

Answer:

Discount percentage = 20%

Step-by-step explanation:

Discount of the sweaters,

→ first sweater = 0%

→ other sweater = 40%

The average discount percent is,

→ (first sweater + other sweater)/2

→ (0% + 40%) ÷ 2

→ (0 + 40)/2

→ 40/2

→ 20% off

Hence, the answer is 20% off.

For, n = 0, 1 we proved that 7⁽ⁿ⁺⁴⁾ - 7ⁿ hence by induction it is divisible by 30 for all n ∈ N.

An inductive proof requires two cases. The first, or base case, establishes the proposition that n = 0 without requiring any prior knowledge of other situations. The second example, the induction step, demonstrates that if the assertion is true for any particular case where n = k, then it must also be true for the subsequent case when n = k + 1. These two actions prove that the statement is true for all n = 1 natural numbers. The base case establishes the truth of the statement for all natural numbers n N, but it does not always start with n = 0. Instead, it frequently starts with n = 1, and it may also start with any fixed natural number n = N.

Given, We have to prove 7⁽ⁿ⁺⁴⁾ - 7ⁿ is divisible by 30 for all n ∈ N.

Let, n = 0.

Therefore,

7⁴ - 7⁰.

= 2401 - 1.

= 2400.

= 30×80, Divisible by 30.

Similarly for n = 1 we have,

7⁵ - 7¹.

= 16807 - 7.

= 16800.

= 30×560.

Hence by induction, the cycle will continue.

Answer: 10 sides

Step-by-step explanation:

You can always use the given formula to calculate but I (personally) find it much easier to calculate the number of sides using the exterior angle.

To calculate the exterior angle, it is 180 - the interior angle.

In this example, the exterior angle would be 180-144 = 36°

Because it is a regular polygon, we know that all the angles in the shape are the same.

In all polygons, the exterior angles always add up to 360 degrees.

So divide 360 by 36 (the size of each exterior angle), and you get 10.

360/36 = 10

Therefore v = log(62) / log(17) is the solution for v, the unknown variable in the equation.

The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be increased in order to obtain a number x is the logarithm of x to the base b.  For example, since 1000 = 10³, the logarithm base 10 of 1000 is 3, or log₁₀ = 3.

A function in mathematics is an expression, rule, or law that establishes the connection between an independent variable and a dependent variable (the dependent variable). Each element of X receives precisely one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

To solve this exponential equation, we can use the logarithms property that is log(a^b) = b*log(a).

Given the equation 17v = 62, we can take the logarithm base 17 of both sides:

log(17^v) = log(62)

v*log(17) = log(62)

Dividing both sides by log(17) gives us:

v = log(62) / log(17)

This is the solution for v, the unknown variable in the equation.
