Answer:

y = 2x + 10

Step-by-step explanation:

(-2,6) and (2,14)

Slope = (14-6)/2- - 2)

= 8/4 = 2

b = 6 - (2)(-2)

= 6 + 4 = 10

Let:

x = number we want to find

the sum of a number and 6 is multiplied by 5:

(x + 6)*5

the result is the same as 7 times the number increased by 16. So:

(x + 6)*5 = 7x + 16

Let's solve for x:

Use distributive property on the left hand side:

5x + 30 = 7x + 16

Subtract 5x from both sides:

5x + 30 - 5x = 7x + 16 - 5x

30 = 2x + 16

Subtract 16 from both sides:

30 - 16 = 2x + 16 - 16

14 = 2x

Divide both sides by 2:

14/2 = 2x/2

7 = x

Any non-empty subset of Rⁿ, where any linear combination of vectors in S is again a vector in S, is a subspace of Rⁿ.

Given that S is a non-empty subset of Rⁿ such that any linear combination of vectors in S is again a vector in S. Therefore, to prove that S is a subspace of Rⁿ, we have to show that S satisfies three conditions. These conditions are as follows;

The condition for being a subspace of Rⁿ

Firstly, a subspace must be closed under addition. In other words, if x and y are any two vectors in S, then their sum x + y must be in S.

Secondly, a subspace must be closed under scalar multiplication. In other words, if x is any vector in S and c is any scalar, then cx must be in S.

Finally, a subspace must contain the zero vector, denoted by 0.S is a subspace of Rⁿ

From the conditions mentioned above, we can show that S is indeed a subspace of Rⁿ, since S satisfies all the required conditions.

Therefore, we can say that any non-empty subset of Rⁿ, where any linear combination of vectors in S is again a vector in S, is a subspace of Rⁿ.

The length of the base of the triangle is 16 m and the height of the triangle is 10 m

A polygon having three edges and three vertices is called a triangle. It is one of the fundamental geometric forms. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.Use the equation area = 1/2 * base * height to determine a triangle's surface area.

The basic Properties of a triangle :

The length of the base = b m

The height of the triangle = b - 6 m

The area of the triangle = 80 m²

Therefore,

(1/2)*b*(b-6) = 80

⇒ b² - 6b = 160

⇒ b² - 6b - 160 = 0

⇒b² - 16b + 10b - 160 = 0

⇒b(b-16) + 10(b- 16) = 0

⇒(b-16)(b =10) =0

The value of b = 16 and b = -10

The value of b is 16 as -10 is negetive and cannot be the length of the triangle.

The height of the triangle = b-6 = 10 m

The minimal expression is: vwxy + vwxz + vxyz.

what is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas. It involves the study of variables, expressions, equations, and functions.

The Quine-McCluskey method is a way to find the minimal expression for a Boolean function. We can use this method to simplify the expression vwxyz + vwxyz + vwxyz + vwxyz + vwxyz + vwxyz.

Step 1: Write out the minterms

We can write out the minterms for the given expression:

vwxyz

vwxyz

vwxyz

vwxyz

vwxyz

vwxyz

Step 2: Group the minterms

We can group the minterms based on the number of 1's in their binary representation. We start with groups of minterms with 0 or 1 1's, and keep combining until we cannot combine any more.

Group 0: (none)

Group 1: 00001, 00010, 00100, 01000, 10000

Group 2: (none)

Group 3: (none)

Group 4: (none)

Step 3: Generate the prime implicants

We can generate the prime implicants by finding all the groups of minterms that differ by only one variable. We can circle the pairs of minterms that differ by only one variable to make it easier to see.

Group 0: (none)

Group 1: 00001, 00010, 00100, 01000, 10000

Group 2: (none)

Group 3: (none)

Group 4: (none)

Prime implicants:

0000_

00_01

0_010

_1000

1_000_

Step 4: Generate the essential prime implicants

The essential prime implicants are the ones that cover at least one minterm that no other prime implicant covers. In this case, all the minterms are covered by multiple prime implicants, so we cannot choose any essential prime implicants.

Step 5: Generate the minimal expression

We can generate the minimal expression by choosing a subset of the prime implicants that covers all the minterms. We can use a table to help us choose the minimal set of prime implicants.

Prime implicant Covered minterms

0000_                     3, 4, 5, 6

00_01                         1, 2, 5, 6

0_010                         1, 2, 4, 6

_1000                         1, 3, 4, 6

1_000_                         0, 2, 3, 5

We can see that all the minterms are covered by the combination of prime implicants 0000_, 00_01, and _1000.

Therefore, the minimal expression is: vwxy + vwxz + vxyz.

The value of x in the triangle is 3.

In the given triangle we have to find the value of x.

Let us form a proportional equation to find value of x.

12.5+x+2/12.5 = 15+2x/15

14.5+x/12.5 = 15+2x/15

15(14.5+x)=12.5(15+2x)

15×14.5 + 15x=12.5×15 +12.5×2x

217.5+15x=187.5+25x

217.5-187.5=25x-15x

The cumulative frequency and relative cumulative frequency for students who earned a score of 20 or lower on the quiz is 29; 58%. (option d)

Cumulative frequency refers to the running total of frequencies, or the sum of frequencies up to a certain point. In this case, the cumulative frequency is the number of students who scored 20 or lower on the quiz.

Relative cumulative frequency, on the other hand, expresses the cumulative frequency as a percentage of the total number of students in the sample. To find the relative cumulative frequency, we divide the cumulative frequency by the total number of students and multiply by 100.

Therefore, for students who scored 20 or lower on the quiz, the cumulative frequency is 29 and the relative cumulative frequency is 58% (29/50 * 100).

Recall that for cumulative frequency we add up all the values that fall above or below a given bin of data. So, if we want all scores less than 20 it should be the first four bins with a total of:

8 plus 8 plus 13 plus 9 equals 38

To get the relative frequency we take the total in the bins for scores of 20 and lower divided by the total of all bins:

38 over 50 equals 0.76 equals 76 percent sign

By the theorem of intersecting secants outside of a circle.

\(3 \times (y + 3) = 2 \times (2 + 6 + 3) \\ 3(y + 3) = 2 \times 11 \\ 3y + 9 = 22 \\ 3y = 22 - 9 \\ 3y = 13 \\ y = \frac{13}{3} \\ y = 4.3 \: cm\)

To find the surface area generated by rotating the curve \($x=e^t-t$\) about the y-axis, we can use the formula for the surface area of revolution:

\($S = 2\pi \int_{a}^{b} f(x) \sqrt{1 + \left(\frac{dy}{dx}\right)^2} dx$\)

In this case, we need to express the curve in terms of y. Let's solve for t in terms of x:

\($x = e^t - t$\)

To isolate t, we take the natural logarithm of both sides:

\($\ln(x+t) = t$\)

Now, differentiate both sides with respect to x using the chain rule:

\($\frac{1}{x+t} \frac{d}{dx}(x+t) = \frac{d}{dx} t$\)

\($\frac{1}{x+t} = \frac{dt}{dx}$\)

Now, we can substitute this expression for  \($\frac{dt}{dx}$\) in the surface area formula:

\($S = 2\pi \int_{a}^{b} f(x) \sqrt{1 + \left(\frac{dy}{dx}\right)^2} dx$\)

\($S = 2\pi \int_{a}^{b} (e^t - t) \sqrt{1 + \left(\frac{1}{x+t}\right)^2} dx$\)

\($S = 2\pi \int_{a}^{b} (e^t - t) \sqrt{1 + \frac{1}{(x+t)^2}} dx$\)

Since we want to rotate about the y-axis, we need to express the integral in terms of y. We know that \($x = e^t - t$\), so we can rewrite the integral as:

\($S = 2\pi \int_{c}^{d} (x(y) - \ln(x(y))) \sqrt{1 + \frac{1}{(x(y)+\ln(x(y)))^2}} \left(\frac{dx}{dy}\right) dy$\)

We can now evaluate the integral to find the surface area. The limits of integration, \($c$\) and \($d$\), depend on the range of y-values that correspond to the curve \($x=e^t-t$.\)

Among the given options, the "Success/Failure Condition" is not a requirement for testing means. The other three options—Randomization, Nearly Normal Condition, and 10% Condition—are necessary conditions to be considered when conducting hypothesis tests on means.

Randomization: Randomization is essential to ensure that the samples being compared are representative of the population and to minimize bias. Random assignment of individuals to treatment groups helps control for confounding variables and increases the validity of the statistical analysis.

Nearly Normal Condition: The Nearly Normal Condition assumes that the data follows a roughly normal distribution within each group being compared. This condition is important because many statistical tests, such as t-tests, rely on the assumption of normality to provide accurate results.

10% Condition: The 10% Condition is relevant when sampling from a finite population. It states that the sample size should be no more than 10% of the population size to ensure that the sampling process does not significantly affect the population distribution.

Success/Failure Condition: The Success/Failure Condition is not directly related to testing means. It is typically associated with tests involving proportions, where the condition specifies that both the number of successes and the number of failures should be at least 10 in each sample or category being compared.

Thus, standard error for this sample of tissue cells infected in a laboratory treatment is 5.33.

The standard error (SE) is a measure of how much the sample mean deviates from the population mean. It is calculated as the standard deviation of the sample divided by the square root of the sample size.

In this case, the sample size is 225, the standard deviation is 80, and the mean is 350. Therefore, the standard error can be calculated as follows:

SE = 80 / √(225)
SE = 80 / 15
SE = 5.33

The standard error for this sample of tissue cells infected in a laboratory treatment is 5.33. This means that the sample mean of 350 is likely to be within 5.33 units of the population mean.

The smaller the standard error, the more precise the estimate of the population mean. In this case, the standard error is relatively small compared to the standard deviation, which suggests that the sample mean is a relatively accurate estimate of the population mean.

However, it is important to note that the standard error only provides information about the precision of the estimate, not its accuracy. Other factors, such as sampling bias or measurement error, could still affect the accuracy of the estimate.

The probability that when the die is rolled twice, the sum is 7 is 0.233.

The probability of rolling each number on the die can be expressed as follows:

P(1) = 1/6, P(2) = 2/6, P(3) = 3/6, P(4) = 4/6, P(5) = 5/6, P(6) = 6/6

To find the probability of rolling a sum of 7 when the die is rolled twice, we can use the concept of the convolution of probability distributions.

We can calculate the probability of obtaining each possible sum by multiplying the probabilities of the individual outcomes that add up to that sum, and then summing these products over all possible combinations of the outcomes. The possible sums that can be obtained when rolling the die twice are 2, 3, 4, ..., 11, 12.

For example, the probability of obtaining a sum of 7 is:

P(1 and 6) + P(2 and 5) + P(3 and 4) + P(4 and 3) + P(5 and 2) + P(6 and 1)

= (1/6)×(6/6) + (2/6)×(5/6) + (3/6)×(4/6) + (4/6)×(3/6) + (5/6)×(2/6) + (6/6)×(1/6)
