The mean height of plants is 18 inches. The height of seven plants are 12 inches, 13 inches, 15 inches, 15 inches, 17 inches, 23 inches, and 24 inches. Find the height of the eighth plant.

That question is not a statistical question since there will be only one answer. If it were to be statistical it would have multiple answers an example of that type of question would be, Why did you decide to try out for the volleyball team? This is statistical because some could say they joined for fun, credits, to do something active, etc.. there would be multiple answers. Your question, How many students tried out for the volleyball team isn't statistical since it will have one answer such as, 26 students, 15 student, 2 students, etc...

Hope this helped!

The question about how many students tried out for a volleyball team relates to statistics. It involves collecting, analyzing, and interpreting numerical data. For example, the number of students trying out for the team can be used as statistical data.

The question 'How many students tried out for the volleyball team?' is one that relates to statistics. This is because it seeks to gather numerical data (in this case, the number of students) related to a specific event (trying out for the volleyball team). Therefore, the process of answering this question would involve collecting, analyzing, interpreting, presenting, or organizing this data.

For instance, let's say that 30 students tried out for the volleyball team. This count is a piece of statistical data which may be further used to compare with previous years, calculate percentages, or make projections for following years.

Answer:

A

Step-by-step explanation:

y=4x+5

x=4y+5

4y+5=x

4y+5-5=x-5

4y=x-5

4y/4= x/4 - 5/4

y= x-5/4

To find the inverse of the function f(x) = 4x + 5, switch x and y in the equation, then solve for y to get the inverse function, which is f-1(x) = (x - 5) / 4.

To find the inverse of the function f(x) = 4x + 5, you would follow these steps:

This inverse function will satisfy the condition that f(f-1(x)) = x and f-1(f(x)) = x, which is the defining property of an inverse function.

Answer:

Step-by-step explanation:

Factor numerator: x^2 + x - 12 = (x + 4)(x - 3)

Factor denominator: x^2 + 7x + 12 = (x + 3)(x + 4)

Notice that the numerator and denominator have a common factor (x + 4).

They can cancel.

What is left is (x - 3)/(x + 3)

Final answer:

To solve the inequality 14 - 3x < -1.14, subtract 14 from both sides, then divide by -3 and remember to reverse the inequality, resulting in the solution set x > -5.05.

Explanation:

To find the solution set of the inequality 14 - 3x < -1.14, follow these steps:

Therefore, the solution set for the inequality is all real numbers greater than -5.05.

The difference between the ratio 5:3 is 2 ( 5-3 = 2)

Nick gets 2 extra shares which is equal to £26

1 share = 26 / 2 = 13

June gets 3 shares: 3 x 13 = £39

June gets 3 shares: 3 x 13 is equal to the $39.

Nick and June win some money and share it in the ratio of 5:3.

Nick gets $26 more than June.

The word difference is the result of subtracting one number from another.

The difference between the ratio of 5:3 is 2 ( 5-3 = 2)

Answer:

The amount of money David spent is $115.

Step-by-step explanation:

Consider the provided information.

David had $350. After shopping, he was left with $235.

Let the money spent by David is c.

As some money are spent from the total amount, So use a "-" sign and put the equation equals to 235, as this is the amount he left with.

The equation can be represented as:

350 - c = 235

Now simplify the above equation in order to find the money spent by David.

Isolate the variable by adding c and subtracting 235 from both sides.

350 - c + c -235 = 235 + c -235

115 =  c

Hence, the amount of money David spent is $115.

Option A: [tex]\lim_{t \to \infty} \frac{64}{1 + 11e^{-.08(\infty)} }  = \frac{64}{1 + 0}  = 64[/tex]

Option B is also true.

Option C:

Step-by-step explanation:

The disciminant [tex]\Delta[/tex] tells you how many real solutions a quadratic equation has, depending on its sign:

[tex]\Delta>0\implies\text{2 solutions}\\\Delta=0\implies\text{1 solution}\\\Delta<0\implies\text{no solutions}[/tex]

ANSWER

0

EXPLANATION

The discriminant of a quadratic equation in the form

[tex]a {x}^{2} + bx + c = 0[/tex]

is given by

[tex]D = {b}^{2} - 4ac[/tex]

The discriminant of a quadratic equation tells us the nature of the roots of that quadratic equation.

If the discriminant is negative, the equation has no real roots.

If the discriminant us positive, the equation has two real roots.

If the discriminant is zero, the equation has a repeated root.

Since the discriminant is -6, the equation has no real roots.

In other words, the number of real roots is 0.

Answer:

The distance between any two corresponding points on ΔXYZ and ΔX'Y'Z′ is equal to [tex]5\ units[/tex]

Step-by-step explanation:

we know that

To find the distance, apply the Pythagoras Theorem

Let

x ----> the distance between any two corresponding points on ΔXYZ and ΔX'Y'Z′

[tex]x=\sqrt{4^{2}+3^{2}} \\ \\x=\sqrt{25}\ units\\ \\x=5\ units[/tex]

first, make an equation:

[tex] - 54 = - 3x - 12[/tex]

then, add twelve to both sides to remove it from the right:

[tex] - 42 = - 3x[/tex]

then just divide by (-3) to get the value of x:

[tex]x = 14[/tex]

The student's question involves setting up and solving a simple algebraic equation. By following the order of operations and isolating the variable, we find that the unknown number is 30.

To solve the problem stated, 'If you subtract 12 from my number and multiply the difference by -3 the result is -54', let's establish a variable to represent the unknown number. Let's call this number 'x'. According to the problem, we need to perform two operations on this number:

1. Subtract 12 from the number x. 2. Multiply the result by -3, which should result in -54.

This establishes the equation:

(x - 12) × -3 = -54

To find x, we'll follow these steps:

Divide both sides of the equation by -3 to isolate the term (x - 12): (x - 12) = -54 / -3 (x - 12) = 18

Add 12 to both sides of the equation to solve for x: x - 12 + 12 = 18 + 12 x = 30

Therefore, the number we're looking for is 30.

The correct answer is C. 604,800.

To calculate this, we can use the formula for permutations:

P(n, k) = n! / (n-k)!

In this case, we have 9 digits (0-9), and we want to create a 7-digit phone number. Since the first digit cannot be 0, we have 9 choices for the first digit, and 9 remaining choices for each subsequent digit (since numbers cannot be repeated).

So, the total number of possible phone numbers is:

P(9, 7) = 9! / (9-7)! = 9 × 8 × 7 × 6 × 5 × 4 × 3 = 604,800

Therefore, the correct answer is C. 604,800.

Answer:

[tex]\sin 75\degree=\frac{\sqrt{2+\sqrt{3}}}{2}[/tex]

Step-by-step explanation:

The haf-angle formula is given by:

[tex]\sin \frac{1}{2}\theta =\sqrt{\frac{1-\cos \theta}{2} }[/tex]

[tex]\sin 75\degree=\sin \frac{1}{2}(150\degree)[/tex].

This implies that:

[tex]\sin \frac{1}{2}(150\degree) =\sqrt{\frac{1-\cos 150\degree}{2} }[/tex]

[tex]\sin \frac{1}{2}(150\degree) =\sqrt{\frac{1--\frac{\sqrt{3}}{2}}{2}}[/tex]

[tex]\sin \frac{1}{2}(150\degree) =\sqrt{\frac{2+\sqrt{3}}{4}}[/tex]

We simplify the square root to obtain:

Answer:

[tex]JP=5\sqrt{3}\ cm[/tex]

Step-by-step explanation:

Connecting points O and E and points O and J, we get triangle EOJ. This triangle is equilateral triangle, because OJ=OE=JE=r=10 cm.

Since EP⊥IJ, then segment JP is the height of the triangle EOJ.

The height of the equilateral triangle can be found using formula

[tex]h=\dfrac{a\sqrt{3}}{2},[/tex]

where a is the side length.

So,

[tex]h=\dfrac{10\sqrt{3}}{2}=5\sqrt{3}\ cm.[/tex]

Answer:

Solution x = - 1

Step-by-step explanation:

3 / (2x+1) = 9 / 3x

Cross multiply

3(3x) = 9(2x + 1)

Distributive property

9x = 18x + 9

Subtract 18x from both sides

-9x = 9

Divide both sides by -9

x = -1

There are two lines from the center of the circle labeled 5.

The lines at 90 degrees from the 5 are chords.  Because both lines are the same distance from the center they are the same length.

The one on the top is labeled as 9, so the line on the bottom is also 9 units long.

X is half the length, so would b 9 /2 = 4.5 units long.

Answer:

(6,4)

Step-by-step explanation:

y = x-2

Now we need to find y

y =4

(6,4)

Answer:

Step-by-step explanation:

For question 4, the top equation has an x and a y value in it. The second equation is just a y value. So put the 4 into the top equation.

4 = x - 2                   Add 2 to both sides

4 + 2 = x -2 + 2

6 = x

You can actually graph this to show that the solution set is (6,4) The solution set is marked (6,4).
