Answer:

y = 32

Step-by-step explanation:

32 x 2 = 64

Hello.

To find the solution of the equation, you must isolate the variable.

Divide both numbers by 2.

y * 2(/2) = 64 (/2)

2 / 2 = 1

64 / 2 = 32

y = 32

Answer:

w ≤ -7

Step-by-step explanation:

The expression |-2w - 1| - 7 ≥ 6 can be simplified as follows:

First, we'll get rid of the absolute value sign by splitting the inequality into two separate cases:

Case 1: -2w - 1 - 7 ≥ 6

-2w - 8 ≥ 6

-2w ≥ 14

w ≤ -7

Case 2: -2w - 1 + 7 ≥ 6

-2w + 6 ≥ 6

-2w ≥ 0

w ≤ 0

So the solution to the inequality is w ≤ -7 or w ≤ 0.

Simplifying further to the solution is w ≤ -7

Answer: w≤−7 or w≥6

Step-by-step explanation:

Step 1: Add 7 to both sides.

|−2w−1|−7+7≥6+7

|−2w−1|≥13

Step 2: Solve Absolute Value.

|−2w−1|≥13

We know either−2w−1≥13or−2w−1≤−13

−2w−1≥13 (Possibility 1)

−2w−1+1≥13+1 (Add 1 to both sides)

−2w≥14

−2w/−2 ≥ 14/−2

(Divide both sides by -2)

w≤−7

−2w−1≤−13 (Possibility 2)

−2w−1+1≤−13+1 (Add 1 to both sides)

−2w≤−12

−2w/−2 ≤ −12/−2

(Divide both sides by -2)

w≥6

The statement that could be used to prove that lines r and s are parallel is given as follows:

It doesn't, because \(\sf{xy\neq x+y}\). In this expression a number x was multiplied by a number y. So this one doesn't check.

One down, three to go.

Step-by-step explanation:

If it is a single digit then round up the number

7 represents the number of spaces the decimal travels to make the given number a single digit.

To find the probability in this scenario, we can use conditional probability and apply Bayes' theorem.

Let's define the following events:

A: Individual has the disease

A': Individual does not have the disease

B1: Test result is positive on the first test

B2: Test result is positive on the second test

We are given:

P(A) = 0.05 (probability of an individual having the disease)

P(A') = 1 - P(A) = 1 - 0.05 = 0.95 (probability of an individual not having the disease)

P(B1 | A) = 0.98 (probability of a positive test result given the individual has the disease)

P(B1 | A') = 1 - P(B1 | A') = 1 - 0.99 = 0.01 (probability of a positive test result given the individual does not have the disease)

We want to find:

P(A | B1, B2) (probability of the individual having the disease given both tests are positive)

Applying Bayes' theorem:

P(A | B1, B2) = [P(B1, B2 | A) * P(A)] / P(B1, B2)

Using the law of total probability:

P(B1, B2) = P(B1, B2 | A) * P(A) + P(B1, B2 | A') * P(A')

Now, since the two test results are independent:

P(B1, B2 | A) = P(B1 | A) * P(B2 | A) = 0.98 * 0.98 = 0.9604

P(B1, B2 | A') = P(B1 | A') * P(B2 | A') = 0.01 * 0.01 = 0.0001

Plugging in the values:

P(B1, B2) = (0.9604 * 0.05) + (0.0001 * 0.95) = 0.04802 + 0.000095 = 0.048115

Finally:

P(A | B1, B2) = [P(B1, B2 | A) * P(A)] / P(B1, B2) = (0.9604 * 0.05) / 0.048115 ≈ 0.9987

Therefore, the probability that the individual has the disease given both tests are positive is approximately 0.9987, or 99.87%.

a. The problem is determining the number of each kind of fish that Paula can buy.

b. The two equations for the system are b + c = 6 and 2.50b + 5.50c = 24.00

c. By using substitution, the value of c is 3 clown loaches.

d. By using substitution, the value of b is 3 blue gouramis.

In this scenario, we can logically deduce that Paula wishes to add some tropical fish to her aquarium and has to determine the number of each kind of fish she should buy.

Part b.

Assuming the variable b represent the number of blue gouramis and the variable c represent number of clown loaches, a system of equations to describe this situation can be written as follows;

b + c = 6  (equation dealing with the number of fish)

2.50b + 5.50c = 24.00 (equation dealing with cost).

Part c.

By using the substitution method, the value of c is given by:

2.50(6 - c) + 5.50c = 24.00

15 - 2.50c + 5.50c = 24.00

-2.50c + 5.50c = 24.00 - 15

3c = 9

c = 9/3

c = 3 clown loaches.

Part d.

By using the substitution method, the value of b from the second equation is given by:

2.50b + 5.50c = 24.00

2.50b + 5.50(3) = 24.00

2.50b = 24.00 - 16.50

b = 7.50/2.50

In this case, because there is a right angle, we can use pythagoras

Option C : The slope is constant for all three pairs of points, we can conclude that the rate of change of the linear relationship is 3/2.

To find the rate of change of a linear relationship, you need to calculate the slope of the line that represents the relationship. The slope of a line can be calculated as the change in y divided by the change in x between any two points on the line.

The rate of change of a linear relationship is equal to its slope.

Using the points (1, 2) and (3, 5) to calculate the slope:

slope = (change in y) / (change in x) = (5 - 2) / (3 - 1) = 3/2

Using the points (3, 5) and (5, 8) to calculate the slope:

slope = (change in y) / (change in x) = (8 - 5) / (5 - 3) = 3/2

Using the points (5, 8) and (7, 11) to calculate the slope:

slope = (change in y) / (change in x) = (11 - 8) / (7 - 5) = 3/2

This means that for every increase of 1 in x, the y value increases by 3/2. So the rate of change of the linear relationship is 3/2 or "three over two". Therefore, the rate of change of the linear relationship is 3/2.

The probability of a randomly chosen test-taker scoring between 139 and 164 is 0.9021.

Probability is the measure of how likely an event is to occur. It is the ratio of the number of favorable outcomes to the total number of possible outcomes. Probability is expressed as a number between 0 and 1, where 0 indicates impossible and 1 indicates certain. Probability is used to analyze the chances of a given event occurring in a given situation. It is an important concept in many areas of study, such as mathematics, statistics, finance, and science.

This can be calculated by using the z-score formula, which is (x - μ) / σ. In this case, x is the score, μ is the mean score, and σ is the standard deviation. The z-score for the score of 139 is (139 - 154) / 5 = -1.8 and the z-score for the score of 164 is (164 - 154) / 5 = 1.8. The probability of scoring between these two z-scores is 0.9021, which can be calculated using the cumulative z-score table.

The given statement: n(n+1)(2n+1) is divisible by 6 for all positive integers n.

Step-by-step explanation: We need to prove that n(n+1)(2n+1) is divisible by 6 for all positive integers n using mathematical induction.

Step 1: First, lets prove the statement for the smallest possible value of n. The smallest value of n is 1. So, let's check whether the given statement is true for n = 1 or not.

\(LHS = 1(1+1)(2*1+1) = 6\)

It is divisible by 6. Hence, the statement is true for n=1.

Step 2: Let's assume that the statement is true for n=k. So, we can say that n(n+1)(2n+1) is divisible by 6 for n=k. i.e., n(n+1)(2n+1) = 6a (for some integer a).

Step 3: We need to prove the statement is true for n=k+1.

So, we need to prove that (k+1){(k+1)+1}[2(k+1)+1] is divisible by 6

Using the assumption we made in step 2.

\(LHS = (k+1){(k+2)}[2k+3] = (k+1)(k+2)(2k+3)LHS = (2k+3)k(k+1)(k+2)LHS = 2[k(k+1)(k+2)] + 3[k(k+1)]\)

Now, k(k+1)(k+2) is divisible by 6 using the assumption made in step 2.

So, LHS = 2[k(k+1)(k+2)] + 3[k(k+1)] is also divisible by 6.

Hence, the statement is true for n=k+1.

Step 4: Using steps 1 to 3, we can say that the given statement is true for n=1 and if it is true for n=k, then it is also true for n=k+1.

Hence, by mathematical induction, we can say that the statement is true for all positive integers n.

Hence, it is proved that n(n+1)(2n+1) is divisible by 6 for all positive integers n.

Additional comments

It is useful to start with the polynomial in standard form (decreasing powers of x), as it is here. That way, if there are any factors of x at the right end of the expression, they will be able to be factored from all terms. Here, the right term is a multiple of x², so x² can be factored from all terms.

Your knowledge of multiplication tables tells you 30 is a multiple of 6. Your knowledge of divisibility rules tells you 84 is even and a multiple of 3 (8+4=12 is a multiple of 3). That means 2·3 = 6 is also a factor of 84. (Most folks learn multiplication tables to 10×10, or maybe 12×12. If the latter, you know 84=7×12, so will be a multiple of 6.) The point here is that you can recognize all of the coefficients as being multiples of 6. Now you know that 6x² is a factor of every term, so is a factor of the expression.

Combine solutions: x=-3 or x=9

Step-by-step explanation:

Answer:

x = - 3, x = 9

Step-by-step explanation:

Given

2| x - 3 | - 5 = 7 ( add 5 to both sides )

2|x - 3 | = 12 ( divide both sides by 2 )

| x - 3 | = 6

The absolute value function always gives a positive value, however, the expression inside the bars can be positive or negative, that is

x - 3 = 6 or - (x - 3) = 6

Solving both equations

x - 3 = 6 ( add 3 to both sides )

x = 9

or

- (x - 3) = 6

- x + 3 = 6 ( subtract 3 from both sides )

- x = 3 ( multiply both sides by - 1 )

x = - 3

As a check

2|9 - 3| - 5 = 2|6| - 5 = 12 - 5 = 7 ← Correct

or

2|- 3 - 3| - 5 = 2|- 6| - 5 = 2 |6| - 5 = 12 - 5 = 7 ← Correct

Thus the solutions are x = - 3, x = 9

For the given standard deviation the minimum value we would assign is 22.the maximum value we would assign is 88.

To calculate the minimum and maximum values based on the given information, we need to consider the standard deviation and the respective interest rates for the 3-year and 10-year periods.

Given:

S = 26.32 (Initial value)

E = 55 (Expected value)

t = 3 (Years)

Standard deviation = 60% (of the expected value)

3-year interest rate = 2.4%

10-year interest rate = 3.1%

To find the minimum value, we will calculate the value at the end of the 3-year period using the lowest possible growth rate.

Minimum value calculation:

Minimum value = E - (Standard deviation * E) = 55 - (0.6 * 55) = 55 - 33 = 22

Therefore, the minimum value we would assign is 22.

To find the maximum value, we will calculate the value at the end of the 10-year period using the highest possible growth rate.

Maximum value calculation:

Maximum value = E + (Standard deviation * E) = 55 + (0.6 * 55) = 55 + 33 = 88

Therefore, the maximum value we would assign is 88.
