Answer:

B(-9) = 432

Step-by-step explanation:

B(x) = 4x² - 12x

B(-9) = 4(-9)² - 12(-9)

B(-9) = 4(81) + 108

B(-9) = 324 + 108

B(-9) = 432

Answer:

432

Step-by-step explanation:

B(x) = - 9

Replacing the value of x in the equation,

4x² - 12x

= 4 * (-9)² - 12 * (-9)

= 4 * 81 + 108

= 324 + 108

= 432

Answer:

y = 0.5x -3 or y = 1/2x -3

Step-by-step explanation:

y = mx+b

m = slope = change in y/change in x = 1 / 2

b = y intercept = (0,-3)

y= 1/2x-3

The equation of the vertical asymptote is x = -3

The function is given as:

\(y =\frac{5x +1}{x + 3}\)

Assume the equation of the function is:

\(y =\frac{m(x)}{n(x)}\)

So, by comparison;

We have:

\(n(x)=x + 3\)

Set n(x) to 0

\(x + 3 = 0\)

Subtract 3 from both sides

\(x = -3\)

Hence, the equation of the vertical asymptote is x = -3

In a series system, the availability is the product of the availability of each individual unit. In a parallel system, the availability is the complement of the probability that all units have failed.

c) To calculate the availability of systems in terms of the availability of individual units:

i) Series: In a series system, the failure of one unit results in the failure of the entire system. Therefore, the availability of the series system is the product of the availability of each individual unit. That is, if we have n units in series with availability A1, A2, ..., An, the availability of the series system is given by:

As = A1 × A2 × ... × An

ii) Parallel: In a parallel system, the system operates as long as at least one unit is functioning. Therefore, the availability of the parallel system is the complement of the probability that all units have failed. That is, if we have n units in parallel with availability A1, A2, ..., An, the availability of the parallel system is given by:

As = 1 - (1 - A1) × (1 - A2) × ... × (1 - An)

Note that the availability of each unit should be expressed as a decimal or a fraction, and not as a percentage.

Hey there! :)

Answer:

x = 12.

Step-by-step explanation:

Given:

\(\frac{3}{5} = \frac{x}{20}\)

Cross multiply to solve for x:

3 · 20 = 5 · x

60 = 5x

Divide by 5:

12 = x.

Answer:

so x=12

Step-by-step explanation:

\(\frac{3}{5}=\frac{x}{20}\\ by cross multiplication\)

3×20=5×x

60=5x

dividing 5 on both sides

60/5=5x/5

x=12

Lindsey would need to use 4/3 cups of sugar to make a full batch of cookies.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can use proportions to solve this problem.

If 2/3 cups of sugar are used to make 1/2 batch of cookies, then we can set up the following ratio:

2/3 cups of sugar : 1/2 batch of cookies

We want to find how much sugar is needed for a full batch of cookies. Let's call this amount x cups of sugar.

We can set up another ratio:

x cups of sugar : 1 full batch of cookies

To solve for x.

(2/3 cups of sugar) x (1 full batch of cookies) = (1/2 batch of cookies) x (x cups of sugar)

2/3 = 1/2 (x)

x = (2/3) / (1/2)

x = 4/3

Therefore,

Lindsey would need to use 4/3 cups of sugar to make a full batch of cookies.

False. The expected cell frequency in statistical analysis, specifically in the context of contingency tables and chi-square tests, is not based on the researcher's opinion. Instead, it is determined through mathematical calculations and statistical assumptions.

In contingency tables, the expected cell frequency refers to the expected number of observations that would fall into a particular cell if the null hypothesis of independence is true (i.e., if there is no relationship between the variables being studied). The expected cell frequency is calculated based on the marginal totals (row totals and column totals) and the overall sample size.

The expected cell frequency is computed using statistical formulas and is not influenced by the researcher's opinion or subjective judgment. It is a crucial component in determining whether the observed frequencies in the cells significantly deviate from what would be expected under the null hypothesis.

By comparing the observed cell frequencies with the expected cell frequencies, statistical tests like the chi-square test can assess the association or independence between categorical variables in a data set.

Thus, the statement "the expected cell frequency is based on the researcher's opinion" is false. The expected cell frequency is derived through statistical calculations and is not subject to the researcher's subjective input.

The intermediate value theorem (IVT) says that if \(f(x)\) is continuous on \([a,b]\), and if \(d\) is a number between

\(\min\{f(a),f(b)\} \le d \le \max\{f(a),f(b)\}\)

then there is some \(c\in(a,b)\) such that \(f(c) = d\).

In this case we have for all \(x\in[5,6]\),

\(-5 \le f(x) \le 5\)

0 falls in this range, so by continuity of \(f\) and the IVT, there must be some number \(x\in(5,6)\) such that \(f(x) = 0\).
