Given: What should be done to both sides of the equation in order to solve y - 4.5 = 12.2?

To Find: What should be done on both side of equation.

Solution:

Step1 : Add 4.5 both sides so that +4.5 gets eliminated from LHS ,

=> y-4.5+4.5=12.2+4.5

=> y = 16.7

Hence the value of y is 16.7.

To need to solve the equation we need to add 4.5 on both sides and the value of y will be 16.7.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

In other words, the equation must be constrained with some constraints.

As per the given equation,

y - 4.5 = 12.2

Add 4.5 on both sides of the equation,

y - 4.5 + 4.5 = 12.2 + 4.5

y = 16.7

Hence "To need to solve the equation we need to add 4.5 on both sides and the value of y will be 16.7".

The experimental study design described is a 2x2 factorial design, where two independent variables (intervention and pretest) are crossed to create four groups for examining the main and interaction effects on the dependent variable.

Factorial designs allow researchers to examine the effects of multiple independent variables on a dependent variable. In this case, the two independent variables are the intervention (receiving vs. not receiving) and the pretest (receiving vs. not receiving). The two levels of each independent variable are crossed to create four different groups, two of which receive the intervention and two of which do not, two of which receive a pretest, and two of which do not.

This design allows the researcher to examine both the main effects of each independent variable and the interaction effects between the two independent variables on the dependent variable.

The statement that is true for the equation 5x - y/3 = 13 and the ordered pairs (2, -9) and (3, -6) is that neither of these ordered pairs satisfies the equation.

In the given equation, we have 5x - y/3 = 13.

To check if the ordered pairs satisfy the equation, we substitute the x and y values from each pair into the equation and see if the equation holds true.

For the ordered pair (2, -9), substituting x = 2 and y = -9 into the equation gives us 5(2) - (-9)/3 = 13, which simplifies to 10 + 9/3 = 13, and further simplifies to 10 + 3 = 13.

However, 13 does not equal 13, so the equation is not satisfied.

Similarly, for the ordered pair (3, -6), substituting x = 3 and y = -6 into the equation gives us 5(3) - (-6)/3 = 13, which simplifies to 15 + 6/3 = 13, and further simplifies to 15 + 2 = 13.

Again, 17 does not equal 13, so the equation is not satisfied.

In summary, for the equation 5x - y/3 = 13, neither the ordered pair (2, -9) nor the ordered pair (3, -6) satisfies the equation when their x and y values are substituted into it.

A manufacturing plant has two assembly lines for producing glass bottles. The manager

was concerned about whether the proportion of defective bottles differs between the two

assembly lines. She gathered two independent samples and found the following data:

n 1 =100, ^p 1 =.1,n 2 =100, ^p 2 =.13.

(a) Set up the appropriate null and alternative hypotheses.

(b) Compute the value of the test statistic.

(c) Draw a conclusion as to whether there is a difference between the two assembly lines

It is important to avoid Type I errors and ensure that the null hypothesis is correctly accepted or rejected based on the results of the hypothesis test. This ensures that the transformer components manufactured by the plant in Alamo, TN are safe and reliable for use.

In this scenario, the plant in Alamo, TN manufactures complex transformer components that need to meet specific safety guidelines. One critical component must deliver 1,000 volts of electricity and cannot absorb more than 3% humidity. To ensure quality control, a hypothesis test is conducted with the null hypothesis (H0) stating that the humidity level absorbed is 3%, and the alternative hypothesis (Ha) stating that the humidity level absorbed is more than 3%. A Type I error in this context would result in rejecting a true null hypothesis. This means that the company would believe that the humidity level absorbed is more than 3%, when in fact it is not more than 3%. This could lead to the company rejecting components that are actually safe to use, leading to a loss in production and revenue.

Answer:

y = x + 4

Step-by-step explanation:

slope = 1

b = 4

Trả lời:

86 và 91

Giải thích từng bước:

Cho hai số là x và y. Nếu tổng của chúng là 177, thì;

x + y = 177 ... 1

Nếu 17 bị trừ đi số đầu tiên, nó được biểu thị là x - 17

Nếu 25 được thêm vào số thứ hai l, nó được biểu thị bằng y + 25

Nếu số thứ nhất bây giờ bằng 2/3 số thứ hai, thì:

x-17 = 2/3 (y + 25) .... 2

Từ 1, x = 177-y ... 3

Thay thế 3 thành 2

177-y-17 = 2/3 (y + 25)

160-y = 2/3 (y + 25)

3 (160-y) = 2 (y + 25)

480-3y = 2y + 50

-3y-2y = 50-480

-5y = -430

y = 430/5

y = 86

Vì x = 177-y

x = 177-86

x = 91

Do đó hai số là 86 và 91

The number of student committees for each scenario is as follows: a. 906,192, b. 250,800, c. 319,290, d. 39,960, e. 39,900, f. 905,268. To determine the number of student committees that can be formed:

From a class of 32 students, with 12 girls and 20 boys, we can follow these steps for each scenario:

a. Choosing the six students at random:

In this case, we need to calculate the number of ways to choose six students out of 32 without any specific requirements.

We can use the combination formula: C(n, r) = n! / (r!(n-r)!), where n is the total number of students and r is the number of students to be chosen.

So, C(32, 6) = 32! / (6!(32-6)!) = 906,192.

b. Committee consisting of 3 girls and 3 boys:

We need to calculate the number of ways to choose 3 girls out of 12 and 3 boys out of 20.

Using the combination formula, C(12, 3) * C(20, 3) = (12! / (3!(12-3)!) * 20! / (3!(20-3)!) = 220 * 1140 = 250,800.

c. Committee with exactly 4 boys:

We need to calculate the number of ways to choose 4 boys out of 20 and 2 remaining students out of the 12 girls.

C(20, 4) * C(12, 2) = (20! / (4!(20-4)!) * 12! / (2!(12-2)!) = 4,845 * 66 = 319,290.

d. Committee with 1 or 2 girls:

We need to calculate the number of ways to choose 1 girl and 5 boys, as well as 2 girls and 4 boys, and then sum the two possibilities.

C(12, 1) * C(20, 5) + C(12, 2) * C(20, 4) = (12! / (1!(12-1)!) * 20! / (5!(20-5)!) + (12! / (2!(12-2)!) * 20! / (4!(20-4)!) = 12,240 + 27,720 = 39,960.

e. Sam and Jordan must be on the committee:

Since Sam and Jordan are both girls and must be on the committee, we need to choose 4 more students out of the remaining 10 girls and 20 boys.

C(10, 4) * C(20, 2) = (10! / (4!(10-4)!) * 20! / (2!(20-2)!) = 210 * 190 = 39,900.

f. Committee with at least one boy:

To calculate this, we need to find the total number of committees and subtract the number of all-girl committees.

Total committees: C(32, 6) = 906,192.

All-girl committees: C(12, 6) = 924.

Committees with at least one boy: 906,192 - 924 = 905,268.

Therefore, the number of student committees for each scenario is as follows:

a. 906,192

b. 250,800

c. 319,290

d. 39,960

e. 39,900

f. 905,268.

A vertical asymptote is a line on the x-axis where the graph of a function approaches infinitely close but does not actually reach. In this case, the vertical asymptote is x = 4.
In exploration 4.3.3, the vertical asymptote for question 2 is at x = -2. Let's see what is meant by a vertical asymptote.What is a vertical asymptote?A vertical asymptote is a line that a function approaches but never touches.

The curve gets arbitrarily close to the vertical line but never touches it. When the function approaches a vertical asymptote, the function approaches infinity or negative infinity.For instance, consider the function f(x) = 1/x. It has a vertical asymptote at x = 0. This is because the function's value becomes increasingly larger as x approaches 0 from the positive side, and the value of the function becomes increasingly smaller as x approaches 0 from the negative side.Therefore, if a curve goes on increasing or decreasing on both sides of a vertical line (called a vertical asymptote), the curve approaches that line but never touches it. This is the basic idea of a vertical asymptote.What is the vertical asymptote for question 2?The rational function f(x) = (x + 2) / [(x + 2)^2 - 4] is being studied in question 2 of exploration 4.3.3. It can be seen that (x + 2)^2 - 4 = (x + 2 - 2)(x + 2 + 2) = (x)(x + 4).Therefore, the denominator (x + 2)^2 - 4 can be written as (x)(x + 4).The vertical asymptotes of a rational function occur where the denominator equals zero. Since the denominator is (x)(x + 4), the vertical asymptotes occur where x = 0 or x = -4.However, x = 0 is not a vertical asymptote because there is a hole in the graph. So, the only vertical asymptote is at x = -2. This means that the curve approaches x = -2 but never touches it. Therefore, the vertical asymptote for question 2 in exploration 4.3.3 is x = -2.

Step-by-step explanation:

First, you need to distribute. Next, you subtract on both sides. Then, you subtract again. Finally, you divide.

(a) The mean of Z in case (a) is -60 and the variance is 400.

(b) The mean of Z in case (b) is 280 and the variance is 3600.

(c) The mean of Z in case (c) is 60 and the variance is 65.

(d) The mean of Z in case (d) is -20 and the variance is 65.

(e) The mean of Z in case (e) is 80 and the variance is 505.

To find the mean and variance of the random variable Z for each case, we can use the properties of means and variances.

(a) Z = 40 - 5X

Mean of Z:

E(Z) = E(40 - 5X) = 40 - 5E(X) = 40 - 5 * 20 = 40 - 100 = -60

Variance of Z:

Var(Z) = Var(40 - 5X) = Var(-5X) = (-5)² * Var(X) = 25 * Var(X) = 25 * (4)² = 25 * 16 = 400

Therefore, the mean of Z in case (a) is -60 and the variance is 400.

(b) Z = 15X - 20

Mean of Z:

E(Z) = E(15X - 20) = 15E(X) - 20 = 15 * 20 - 20 = 300 - 20 = 280

Variance of Z:

Var(Z) = Var(15X - 20) = Var(15X) = (15)² * Var(X) = 225 * Var(X) = 225 * (4)² = 225 * 16 = 3600

Therefore, the mean of Z in case (b) is 280 and the variance is 3600.

(c) Z = X + Y

Mean of Z:

E(Z) = E(X + Y) = E(X) + E(Y) = 20 + 40 = 60

Variance of Z:

Var(Z) = Var(X + Y) = Var(X) + Var(Y) = (4)² + (7)² = 16 + 49 = 65

Therefore, the mean of Z in case (c) is 60 and the variance is 65.

(d) Z = X - Y

Mean of Z:

E(Z) = E(X - Y) = E(X) - E(Y) = 20 - 40 = -20

Variance of Z:

Var(Z) = Var(X - Y) = Var(X) + Var(Y) = (4)² + (7)² = 16 + 49 = 65

Therefore, the mean of Z in case (d) is -20 and the variance is 65.

(e) Z = -2X + 3Y

Mean of Z:

E(Z) = E(-2X + 3Y) = -2E(X) + 3E(Y) = -2 * 20 + 3 * 40 = -40 + 120 = 80

Variance of Z:

Var(Z) = Var(-2X + 3Y) = (-2)² * Var(X) + (3)² * Var(Y) = 4 * 16 + 9 * 49 = 64 + 441 = 505

Therefore, the mean of Z in case (e) is 80 and the variance is 505.

The standard deviation of wait time is 13.8564.

The length of time patients must wait to see a doctor in a local clinic is uniformly distributed between 25 minutes and 73 minutes. We have to find the standard deviation of the wait time.

The square root of the variance of a random variable, sample, statistical population, data collection, or probability distribution is its standard deviation. The standard deviation in statistics is a measure of the degree of variation or dispersion in a set of values. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.

S² = (73 - 25)²/12

S² = (48)²/12
