The result to the equation is x = 7.

To find the results of the equation √( 2x- 5) 4 = 1, we can break it step by step

Abate 4 from both sides of the equation

√( 2x- 5) = 1- 4

√( 2x- 5) = -3

Square both sides of the equation to exclude the square root

√( 2x- 5))² = (- 3)²

2x- 5 = 9

Add 5 to both sides of the equation

2x = 9 + 5

2x = 14

Divide both sides of the equation by 2

x = 14/2

x = 7

Thus, the result to the equation is x = 7.

Checking the extraneous result

Substituting x = 7 back into the original equation

√(2(7)-5)+4=1

√(14-5)+4=1

Answer:

-7

(If you like this answer i would appreciate if u give brainliest but otherwise, i hope this helped ^^)

Step-by-step explanation:

To find the value of t, we can use the formula for the slope of a line:

m = (y2 - y1) / (x2 - x1)

Given that the slope of the line is 0, we have:

0 = (-7 - t) / (5 - 3)

To solve for t, we can cross-multiply:

0 * (5 - 3) = -7 - t

0 = -7 - t

To isolate t, we can add 7 to both sides:

7 = -t

Dividing both sides by -1, we get:

t = -7

Therefore, the value of t is -7.

The estimated proportion of adults in the country who have donated blood in the past two years is approximately 0.1803 or 18.03%. the 95% confidence interval for the proportion of adults in the country who have donated blood in the past two years is approximately 0.1589 to 0.2017.

(a) Estimate the proportion of adults in the country who have donated blood in the past two years.

To estimate the proportion of adults who have donated blood, we divide the number of adults who have donated blood by the total number of adults surveyed.

Number of adults who have donated blood = 414

Total number of adults surveyed = 2290

Proportion of adults who have donated blood = Number of adults who have donated blood / Total number of adults surveyed

Proportion of adults who have donated blood = 414 / 2290

Proportion of adults who have donated blood ≈ 0.1803 (rounded to four decimal places)

Therefore, the estimated proportion of adults in the country who have donated blood in the past two years is approximately 0.1803 or 18.03% (rounded to two decimal places).

(b) Construct a 95% confidence interval for the proportion of adults in the country who have donated blood in the past two years.

To construct a confidence interval, we can use the formula for a proportion with a confidence level of 95%:

Confidence interval = Sample proportion ± Margin of error

Sample proportion = Proportion of adults who have donated blood = 0.1803 (from part a)

Margin of error = Z * √[(Sample proportion * (1 - Sample proportion)) / Sample size]

Z represents the critical value for a 95% confidence level. Since the sample size is large (n > 30), we can use the standard normal distribution and take Z = 1.96.

Sample size = Total number of adults surveyed = 2290

Margin of error = 1.96 * √[(0.1803 * (1 - 0.1803)) / 2290]

Calculating the margin of error:

Margin of error ≈ 1.96 * √[(0.1803 * 0.8197) / 2290]

Margin of error ≈ 0.0214 (rounded to four decimal places)

Confidence interval = 0.1803 ± 0.0214

Lower bound = 0.1803 - 0.0214 ≈ 0.1589 (rounded to four decimal places)

Upper bound = 0.1803 + 0.0214 ≈ 0.2017 (rounded to four decimal places)

Therefore, the 95% confidence interval for the proportion of adults in the country who have donated blood in the past two years is approximately 0.1589 to 0.2017 (or 15.89% to 20.17%, rounded to two decimal places).

(c) Interpret the confidence interval in the context of the problem.

The confidence interval provides a range of values within which we can be 95% confident that the true proportion of adults in the country who have donated blood lies. Based on the survey data, the estimated proportion is 18.03% (from part a). The 95% confidence interval for this proportion is approximately 15.89% to 20.17%.

This means that we are 95% confident that the true proportion of adults in the country who have donated blood in the past two years falls within this range. In other words, if we were to repeat the survey multiple times and construct confidence intervals, approximately 95% of those intervals would contain the true proportion.

Therefore, based on this survey, we can conclude that the proportion of adults who have donated blood in the past two years in the country is likely to be between 15.89% and 20.17%, with a confidence level of 95%.

The expression simplifies to |2x| = -2x, when x<0 by definition of absolute value

If x<0, then the expression |2x| simplifies to -2x.

The absolute value of a number is the distance of the number from zero on the number line.

Since x is negative in this case, 2x will be negative as well.

Taking the absolute value of -2x will give us the opposite of -2x, which is 2x.

However, since we know that x<0, this means that -2x will always be a positive number.

The measure of the angle ∠S is 95°

Let's call angle Q as x. Then we can express the other angles in terms of x as follows:

Angle R = x + 25 (since angle R is 25° more than angle Q)

Angle S = x + 65 (since angle S is 65° more than angle Q)

We know that the sum of the angles in a triangle is always 180°, so we can write:

x + (x + 25) + (x + 65) = 180

Simplifying this equation, we get:

3x + 90 = 180

Subtracting 90 from both sides, we get:

3x = 90

Dividing both sides by 3, we get:

x = 30

Therefore, angle S is:

x + 65 = 30 + 65 = 95 degrees

So the measure of angle S is 95 degrees.

[tex]150 $ choose 10 = 150! / (10! \times (150 - 10)!) = 2,535,316,699,000[/tex]

To calculate the probability of exactly 4 students from your school being selected as contestants, we need to count the number of ways this can happen and divide it by the total number of possible outcomes.

There are 30 students from your school and 120 students from other schools in the audience.

We need to choose 4 students from your school and 6 students from other schools for the contestant spots.

The number of ways to do this is:

[tex]30 $ choose 4 \times 120 $ choose 6 = (30! / (4! \times 26!)) \times (120! / (6! \times 114!)) = 23,400,140,040,000[/tex]

Answer:

(-1, 3 1/4) and (3, 12 3/4)

Step-by-step explanation:

These are the only two pairs that will work for the graph.

Step 1: Find a common denominator.

The denominators are 3y, 4, and 8. The least common multiple (LCM) of these is 24y.

Step 2: Adjust each term to have a denominator of 24y.

To do this, we multiply the numerator and denominator of each term by the appropriate factor:

For the term 8/3y, multiply numerator and denominator by 8: (8/3y) * (8/8) = 64/24y.

For the term 5y/4, multiply numerator and denominator by 6y: (5y/4) * (6y/6y) = 30y^2/24y.

For the term 5/8, multiply numerator and denominator by 3: (5/8) * (3/3) = 15/24y.

Step 3: Combine the terms.

Now that all terms have a common denominator of 24y, we can add them together:

(64/24y) + (30y^2/24y) - (15/24y)

Step 4: Combine the numerators.

Add the numerators of the fractions:

(64 + 30y^2 - 15) / 24y

Step 5: Simplify the numerator.

Combine like terms in the numerator:

(49 + 30y^2) / 24y

Thus, the simplified expression is (49 + 30y^2) / 24y, considering all permissible values of y.

"The correct answer is: g(x), f(x), h(x)."To determine the correct order of the functions from least to greatest according to the average rate of change on the interval from x = 0 to x = 4, we need to calculate the average rate of change for each function.

The average rate of change is calculated by finding the difference in the function's values at the endpoints of the interval (x = 4 and x = 0) and dividing it by the difference in the corresponding x-values.

For function f(x), we have:

Average rate of change = (f(4) - f(0))/(4 - 0) = (64 - 0)/(4 - 0) = 64/4 = 16

For function g(x), since it is a linear graph, the average rate of change is constant throughout. Therefore, the average rate of change for g(x) is the same as the slope of the line, which is determined by the ratio of the change in y to the change in x. In this case, it would be the slope between the given x-intercept (-2) and y-intercept (-1), which is -1/2.

For function h(x), we need to find the average rate of change between x = 0 and x = 4. Substituting the values, we get:

Average rate of change = (h(4) - h(0))/(4 - 0) = (36 - 6)/(4 - 0) = 30/4 = 7.5

Now, let's compare the average rates of change for each function:

f(x): 16

g(x): -1/2

h(x): 7.5

From least to greatest, the correct order according to the average rate of change is:

c) [0, ∝) is a reasonable domain for this function.

d) The patient must receive the next intravenous dose of the drug between 0.75 and 1.35 hours after the initial dose.

e) The concentrations of the two drugs cannot be compared

A. To find when the concentration will be 0.5 mg/L, we can set the function equal to 0.5 and solve for t:

20t c(t)-20 2 +4 = 0.5

20t c(t)-20 2 = 3.5

20t c(t) = 2

3.5c(t) = 1.175

So the concentration will be 0.5 mg/L at approximately 1.18 hours.

B. Using the given formula, we can complete the table as follows:

| t    | c(t)         |

0    | 4            |

2    | 2.86        |

4    | 2.14         |

16   | 0.44         |

18   | 0.34         |

20   | 0.27        

C. Because time cannot be negative and the function has no imaginary values, the domain of the function is all non-negative real numbers.

As a result, [0,] is a reasonable domain for this function.

D. To maintain a concentration above 1 mg/L and below 8 mg/L, we need to solve the inequality:

1 < 20t

c(t)-20 2 +4 < 8

Simplifying this inequality, we get:

0.75 < t < 1.35

To maintain the desired concentration, the patient must receive the next intravenous dose of the drug between 0.75 and 1.35 hours after the initial dose.

Answer:

The value of y is -5, so the ordered pair is (9, -5).

Step-by-step explanation:

To determine the value of y for the ordered pair (9, y) on the line AC, we first need to find the equation of the line AC.

To find the slope of the line AC, substitute the points A and C into the slope formula:

[tex]\textsf{Slope}\;(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{y_C-y_A}{x_C-x_A}=\dfrac{-3-1}{4-(-6)}=\dfrac{-4}{10}=-\dfrac{2}{5}[/tex]

To determine the equation of line AC, substitute the found slope and one of the points into the point-slope formula:

[tex]\begin{aligned}y-y_1&=m(x-x_1)\\\\y-1&=-\dfrac{2}{5}(x-(-6)\\\\y-1&=-\dfrac{2}{5}x-\dfrac{12}{5}\\\\y&=-\dfrac{2}{5}x-\dfrac{7}{5} \end{aligned}[/tex]

Now we have found the equation of the line AC, to determine the value of y for the ordered pair (9, y), substitute x = 9 into the equation:

[tex]\begin{aligned}y&=-\dfrac{2}{5}(9)-\dfrac{7}{5}\\\\&=-\dfrac{18}{5}-\dfrac{7}{5}\\\\&=\dfrac{-18-7}{5}\\\\&=\dfrac{-25}{5}\\\\&=-5\end{aligned}[/tex]

Therefore, the value of y for the ordered pair is y = -5.

So the ordered pair is (9, -5).
