Answers
The answer is 5.1 completes the inequality.
What are inequalities?.You may use the inequalities to solve almost any inequality or set of inequalities using just one variable. You can usually find precise answers.To provide you with approximate solutions to practically any level of accuracy you require, even when this is not possible.Additionally, you can display the regions that satisfy one or more inequalities between two variables to clearly observe where those regions cross.The Plot command, from the Graphs section, will plot any inequality involving two variables. In order to plot the region satisfied by a single inequality involving x and y, go to the basic inequality plotting page, where you can enter the inequality and specify the upper and lower limits on x and y that you want the graph to be plotted for.The advanced inequality plotting page allows you to plot the union or intersection of up to 8 regions on the one graph. You have control over such things as whether or not to show the axes, where the axes should be located and what the aspect ratio of the plot should be. In addition, you have the option of showing each individual region.
Hence, The answer is 5.1 completes the inequality.

Oreduction; 2
O enlargement;
1/2
Answers
Answer:
enlargement ; 2
Step-by-step explanation:
dilation is change in the size of the figure.
in the given scenario, figure's size is increasing so dilation is called enlargement and scale factor must be greater than 1.
scale factor = dimension of new shape / dimension of original shape
let's calculate the difference in terms of boxes of both figures to calculate the scale factor,
scale factor = 6/3

Answers
y = 3x -5 is the equation of the line parallel to the line and going through the point (4,7). The format is slope intercept.
Slope intercept is what?A method of formulating a line's equation that makes it simple to identify the slope and y-intercept is known as the slope-intercept form. The point where the line crosses the y-axis is known as the y-intercept, and the slope refers to how steep the line is.
Using the information provided,
y= 3x – 5
First, we must keep in mind that parallel lines have an equal slope.
In essence,
m1 = m2 if line 1 and 2 are parallel.
Y = mx + c is the slope-intercept form of the equation; y = 3x + 6, which already has this form.
incline of the m1 = 3.
Consequently, m1 = 3 = m2.
The slope of the parallel line, m2 = 3 and the line passes through the point (4,7).
Therefore;
3 = (y - 7)/(x-4)
By cross product;
3x - 12 = y - 7
y = 3x - 5

in a large population, 71% of the people have been vaccinated. if 5 people are randomly selected, what is the probability that at least one of them has been vaccinated?
Answers
The probability that AT LEAST ONE of them has been vaccinated is 0.9979.
Vaccination rate among the population: p = 0.71
Sample size = 5
Assume that X people have received vaccinations.
P(atleast one) = 1 - P (none)
By the binomial distribution, now,
P(none)= (⁵₀) 0.71° (1-0.71)⁵⁻⁰
= 1 × 1 (0.29)⁵
= 0.0021
So,
P(at least one) therefore equals 1 - P (none)
= 1 - 0.0021
= 0.9979
Therefore, the probability that AT LEAST ONE of them has been vaccinated is 0.9979

A rancher has 3000 feet of fencing with which to construct adjacent, equally sized rectangular pens as shown in the figure above. What dimensions should these pens have to maximize the enclosed area?
Answers
The required dimensions of a rectangular rancher with perimeter for fencing, 3000 feet are equal the 500 feet and 375 feet at maximum area of 3,75,000 ft².
We have a rancher which to construct adjacent, equally sized rectangular pens with the fencing of 3000 feet. Suppose that the rancher need to be fenced in the way shown in the attached figure. Then, the perimeter is 4x + 3y = 3000
=> x \( =\frac{3000 - 3y}{4} \).
The area of rectangle is represented by A=L × W --(1) , where L and W are dimensions of rectangles. The total area will be A = 2× x × y --(2)
=> A = 2× (\(\frac{3000 - 3y}{4}\))× y
= ( \( 1500 - \frac{3y}{2} \))y
= \( 1500y - \frac{3y²}{2} \)
Now, differentiate above area function, with respect to y, and equate to 0, for determining the critical points on the graph, \(\frac{dA}{dy} \) = A'(y) =\( 1500 - \frac{6y}{2} \) = 0
=> y = \(\frac{1500}{3} = 500 \)
Also, x \( =\frac{3000 - 3× 500}{4} \).
\( =\frac{1500}{4} = 375 \).
Maximum area = 375 × 500 × 2 = 375000 ft². Hence, the dimensions that will give the maximum area are 500 feet and 375 feet.

Answers
To solve the given problems, we'll use the properties of the normal distribution with mean μ = 100 and standard deviation σ = 10.
a. Probability that X > 85:
To find this probability, we need to calculate the area under the normal curve to the right of 85. We can use the standard normal distribution table or a calculator to find the corresponding z-score and then use the z-table to find the probability.
First, let's calculate the z-score:
z = (X - μ) / σ
z = (85 - 100) / 10
z = -15 / 10
z = -1.5
Using the z-table or a calculator, we find that the probability of Z > -1.5 is approximately 0.9332.
Therefore, the probability that X > 85 is 0.9332 (rounded to four decimal places).
b. Probability that X < 80:
Similarly, we'll calculate the z-score for X = 80:
z = (X - μ) / σ
z = (80 - 100) / 10
z = -20 / 10
z = -2
Using the z-table or a calculator, we find that the probability of Z < -2 is approximately 0.0228.
Therefore, the probability that X < 80 is 0.0228 (rounded to four decimal places).
c. Probability that X < 90 or X > 130:
To calculate this probability, we'll find the individual probabilities of X < 90 and X > 130, and then subtract the probability of their intersection.
For X < 90:
z = (90 - 100) / 10
z = -10 / 10
z = -1
Using the z-table or a calculator, we find that the probability of Z < -1 is approximately 0.1587.
For X > 130:
z = (130 - 100) / 10
z = 30 / 10
z = 3
Using the z-table or a calculator, we find that the probability of Z > 3 is approximately 0.0013.
Since these events are mutually exclusive, we can add their probabilities:
P(X < 90 or X > 130) = P(X < 90) + P(X > 130)
P(X < 90 or X > 130) = 0.1587 + 0.0013
P(X < 90 or X > 130) = 0.1600
Therefore, the probability that X < 90 or X > 130 is 0.1600 (rounded to four decimal places).
d. 99% of the values are between what two X-values (symmetrically distributed around the mean)?
To find the two X-values, we need to find the corresponding z-scores for the cumulative probabilities of 0.005 and 0.995. These probabilities correspond to the tails beyond the 99% range.
For the left tail:
z = invNorm(0.005)
z ≈ -2.576
For the right tail:
z = invNorm(0.995)
z ≈ 2.576
Now we can find the corresponding X-values:
X1 = μ + z1 * σ
X1 = 100 + (-2.576) * 10
X1 = 100 - 25.76
X1 ≈ 74.24
X2 = μ + z2 * σ
X2 = 100 + 2.576 * 10
X2 = 100 + 25.76
X2 ≈ 125.76
Therefore, 99% of the values are greater than 74.24 and less than 125.76 (rounded to two decimal places).

\(\begin{gathered} r^2+16r-48+48=-162+48_{}^{}_{} \\ r^2+16r=-114 \end{gathered}\)Now, to complete the square, divide 16 by 2 and find the square. Then, add that to both sides of the equation:
\(\begin{gathered} r^2+16r+(\frac{16}{2})^2=-114+(\frac{16}{2})^2 \\ r^2+16r+64=-114+64 \\ \Rightarrow(r+8)^2=-50 \end{gathered}\)That is the equation after completing the square.
To find the solutions of r, find the square root of both sides of the equation and simplify:
\(\begin{gathered} r+8=\sqrt[]{-50} \\ r+8=\pm5\sqrt[]{2}i \\ \Rightarrow r=-8+5\sqrt[]{2}i;r=-8-5\sqrt[]{2}i \end{gathered}\)Those are the solutions.
b) We want to solve the quadratic equation given by completing the square:

\(\begin{gathered} m^2+4m-20+20=44+20 \\ \Rightarrow m^2+4m=64 \end{gathered}\)Now, to complete the square, divide 4 by 2 and find the square. Then, add that to both sides of the equation:
\(\begin{gathered} m^2+4m+(\frac{4}{2})^2=64+(\frac{4}{2})^2 \\ m^2+4m+4=64+4 \\ (m+2)^2=68 \end{gathered}\)That is the equation after completing the square.
To find the solutions of m, find the square root of both sides of the equation and simplify:
\(\begin{gathered} m+2=\sqrt[]{68} \\ m+2=\pm2\sqrt[]{17} \\ \Rightarrow m=-2+2\sqrt[]{17};m=-2-2\sqrt[]{17} \end{gathered}\)Those are the solutions.
evaluate the expression under the given conditions. tan(2); cos() = 7 25 , in quadrant i
Answers
The required answer is the value of tan(2) is approximately -2352/3669.
To evaluate the expression under the given conditions, we will first determine the value of sin() using the Pythagorean identity and then use the double-angle formula for tan(2).
A Quadrant is circular sector of equal one quarter of a circle ,or a half semicircle. A sector of two-dimensional cartesian coordinate system. The Pythagorean identity, are useful expression involving the function need to simplified.
Given: cos() = 7/25, and is in Quadrant I.
Step 1: Find sin()
Since we are in Quadrant I, sin() is positive. Using the Pythagorean identity, sin^2() + cos^2() = 1, we can find sin().
sin^2() + (7/25)^2 = 1
sin^2() = 1 - (49/625)
sin^2() = (576/625)
sin() = √(576/625) = 24/25
we are called the Pythagorean identity is Pythagorean trigonometric identity, is expression A to B .
The same value for all variables within certain range. Angle is double or multiply by 2 so we called double- angle.
Step 2: Find tan(2) using the double-angle formula
The double-angle formula for tangent is: tan(2) = (2 * tan()) / (1 - tan^2())
First, we find tan():
tan() = sin() / cos() = (24/25) / (7/25) = 24/7
Now, use the formula for tan(2):
tan(2) = (2 * (24/7)) / (1 - (24/7)^2)
tan(2) = (48/7) / (1 - 576/49)
tan(2) = (48/7) / ((49 - 576) / 49)
tan(2) = (48/7) * (49 / (-527))
tan(2) = (-2352 / 3669)
So, under the given conditions, the value of tan(2) is approximately -2352/3669.
