The group that has a higher percentage is the low income voters.

A percentage simply has to do with the a value or ratio which can be stated as a fraction of 100. It should be noted that when we want to we calculate a percentage of a number, we simply divide it and then multiply the value that is gotten by 100.

In this case, 60 out of a sample of 70 high income voters. The percentage will be:

= 60/70 × 100.

= 85.7%

Also, 90 out of a sample of 100 low income voters supported the introduction of a new national security tax. The percentage will be:

= 90/100 × 100

= 90%

Answer:

Name? Binomial

Degree? 2nd

Step-by-step explanation:

We are given two terms which are 3x² and -x. This makes the polynomial a binomial (because bi- means two). Additionally, the leading degree of the polynomial is 2 because that is the greatest exponent in the expression, so it's a second-degree binomial.

The solution of the function 3f(1) - 4g(-2)  is -19.

The functions can be solved as follows;

f(x) = 7x - 4

g(x) = 11 - x²

Therefore, let's solve the composite function as follows:

A composite function is generally a function that is written inside another function.

Hence,

3f(1) - 4g(-2) = ?

f(1) = 7(1) - 4 = 7 - 4 = 3

g(-2) = 11 - (-2)² = 11 - 4 = 7

Therefore,

3f(1) - 4g(-2) = 3(3) - 4(7) = 9 - 28 = -19

When 7/8 of the candy bar is split into 3/10 of the bar, the candy bar can make around 2 servings.

In mathematics, a fraction is represented by a number that identifies a portion of a whole. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Given that there is 7/8 of the candy bar. The bar is needed to be further divided into 3/10 of the bar, this can be calculated as follows:

[tex]\frac{\frac{7}{8} }{\frac{3}{10} } = \frac{7}{8} * \frac{10}{3} = 2.91[/tex]

A function's inverse will result in the input and output being in opposite directions. Set the function equal to y in order to use algebra to discover the inverse of the function. After that, switch x and y and find y in terms of x.

Inverse operations are those that are the exact opposite of one another. For instance, division is related to the operation of multiplication, and subtraction is the related to operation of addition.

Therefore, in mathematics, an inverse operation is an operation that reverses the effects of a preceding operation The term "inverse operations" refers to a collection of two opposing operations. As an illustration: The result of adding 5 and 2 pens is 7 pens. Now

The percentage of failures, if the minimum for a pass is 35 marks, is given as follows:

80%.

A percentage is obtained applying a proportion, as the percentage is given by the division of the number of desired outcomes by the number of total outcomes, and then multiplied by 100%.

The total number of students is given as follows:

42 + 38 + 120 + 84 + 48 + 36 + 32 = 400.

The minimum grade for a pass is of 35 marks, hence, considering all the measures in the 31-40 range as passing, the number of students that passed is given as follows:

120 + 84 + 48 + 36 + 32 = 320.

Hence the percentage of students that passed is given as follows:

P = 320/400 x 100% = 0.8 x 100% = 80%.

The function with which the projectile is moving is P(t) = 5t - t², where P(t) represent the height and t represent the time.

For t > 5 the value of P(t) will be negative , but distance travelled can not be negative.

an expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable (the dependent variable). Functions can be found everywhere in mathematics, and they are essential for building physical connections in the sciences. The modern definition of function was first proposed in 1837 by the German mathematician Peter Dirichlet:

A variable y is said to be a function of the independent variable x if there is a correlation between them such that a rule determines a particular value of y whenever a numerical value is assigned to x.

The function is P(t) = 5t - t²

here for t > 5 the value of P(t) will be negetive , but distance travelled can not be negetive.

The inverse of the function f(x) = 4x is:

h(x) = 4/x

Two functions f(x) and g(x) are inverses if:

f( g(x)) = x

g( f(x)) = x

Here we want to find the inverse of the function:

f(x) = 4x

So let's assume that h(x) is the inverse, then the composition must be equal to x:

f(h(x)) = 4*h(x) = x

Now we can solve that for h(x), then we will get:

h(x) = x/4

That is the inverse of function f(x).

It is estimated that there is a 0.039 percent chance that a battery may be deemed defective by the quality control team.

Generally, Probability is the area of mathematics that deals with providing numerical descriptions of the likelihood that an event will take place or the likelihood that a statement will be correct.

A number between 0 and 1 may be thought of as representing the chance of an event happening, with 0 indicating that the occurrence is impossible and 1 indicating that it will definitely happen.

Let's call the probability that a battery is faulty "F" and the probability that it is declared faulty by the quality control team "D." We can then use the following formula to find the probability that a battery is declared faulty:

P(D|F) * P(F) + P(D|not F) * P(not F)

Substituting in the given values, we get:

(0.97 * 0.02) + (0.02 * 0.98) = 0.039

So, the probability that a battery is declared faulty by the quality control team is approximately 0.039

B. If two cones have their heights in the ratio 1:3 and radii 3:1, then the ratio of their volumes is 3:1.

This can be determined by using the formula for the volume of a cone, V = (1/3)πr^2h, where r is the radius and h is the height. Since the ratio of the height is 1:3 and the ratio of the radii is 3:1, the ratio of the volumes is 3:1.

To calculate this, we can set up two equations:

V1 = (1/3)πr1^2h1 and

V2 = (1/3)πr2^2h2.

Since the ratio of the height is 1:3, we can set h1=3h2. Substituting this into the equation for V2 and solving for V2/V1, we get

V2/V1 = (r2/r1)^2*(h2/h1).

Since the ratio of the radii is 3:1, we can set r2/r1=3. Substituting this into the equation and simplifying, we get V2/V1 = 3^2*(h2/h1), which is equal to 3^2*1/3=3, which is the same as the ratio of the radii, 3:1. Therefore, the ratio of the volumes is 3:1.

Step-by-step explanation:

using the properties of logarithms

• logx - logy = log ([tex]\frac{x}{y}[/tex] )

• loga = log b ⇒ a = b

given

ln x - ln 2 = ln 3 - ln(x + 1)

ln ([tex]\frac{x}{2}[/tex] ) = ln( [tex]\frac{3}{x+1}[/tex] )

[tex]\frac{x}{2}[/tex] = [tex]\frac{3}{x+1}[/tex] ( cross- multiply )

x(x + 1) = 6

x² + x = 6 ( subtract 6 from both sides )

x² + x - 6 = 0 ← in standard form

(x + 3)(x - 2) = 0 ← in factored form

equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = 0 3

x - 2 = 0 ⇒ x = 2

Step-by-step explanation:

Jan has 12 ounces milkshakes. Four ounces in the milkshake are vanilla and the rest is chocolate. What are 2 equivalent fractions that represent the fraction of the milkshake that is vanilla?

Total in 1 milkshake: 12 oz

Vanilla: 4 oz

Chocolate: 8 oz (12 oz - 4 oz = 8 oz)

The vanilla fraction is

4/12

Reduce 4/12 by dividing the numerator and denominator by 4:

1/3

Multiply the numerator and denominator by 10:

10/30

Here are 3 equivalent fractions of the fraction of vanilla:

4/12, 1/3, 10/30

By taking a quotient, we will see that each one of the 140 people got  GH¢0.67

We know that some people wants to divide equally the amount of GH¢40.00 between a total of 140 people, then we only need to take the quotient:

GH¢40.00/140

Assuming you can't use a calculator, the division is as follows:

40/140   (i removed the units so it is easier to read)

We can simplify the fraction as:

40/140 = 4/14

4/14 = 2/7

Now we could say that each person got GH¢ 2/7

Or write that fraction as 2/7 = 0.67

8³/30 is the expression in simplified form of 2/135*6 - 3√15*6.

The simplest form of a fraction is one with a relatively prime numerator and denominator. It indicates that, other than 1, there is no common factor between the fraction's numerator (upper part or top) and denominator (lower part or bottom).

The reduced form of a fraction is another name for its simplest form. For instance, the simplest form of a fraction with a common factor of 1 is 3/4 However, because 2/4 can be further condensed and written as 1/2, it is not the simplest form. In this case, we can also state that 1/2 and 2/4 are equivalent fractions.

Given to find the expression in simplified form

2/135 *6 - 3√15 *6

6(2/135-3√15)

6(2/3√15-3√15)

6(2/3√15×3√15 - 3√15/ 3√15)

6(2×3√15/135- 3√15/1)

6(2×3√15/3√15- 3√15/1)
