Using the empirical rule, what percentage of the games that Tariq bowls does he score between 80 and 140
Using the Empirical Rule, it is found that Tariq scores between 80 and 140 in 99.7% of the games that he bowls.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, considering the mean of 110 and the standard deviation of 10, scores between 80 and 140 are within 3 standard deviations of the mean, hence Tariq scores between 80 and 140 in 99.7% of the games that he bowls.

What is the 8th term of this geometric sequence?
1, 3, 9, 27,...
Answer:
1*3*3*3*3*3*3=729. For each term you multiply the previous term by three.
Answer:
2187
Step-by-step explanation:
To find the 8th term, we can find and use the explicit formula.
The standard form of the explicit formula for a geometric sequence is:
\(x_n=a(r)^{n-1}\)
Where a is the initial term, r is the common ratio, and n is the nth term.
From the sequence, we can see that the first term is 1, and each term is 3 times the previous term. Thus, the common ratio is 3.
Substituting these into our equation, we will have:
\(x_n=1(3)^{n-1}\\x_n=(3)^{n-1}\)
So, to find the 8th term, substitute 8 for n:
\(x_8=(3)^{8-1}\)
Subtract:
\(x_8=(3)^7\)
Evaluate:
\(x_8=2187\)
So, the 8th term is 2187.
And we're done!
Which equation matches the table?
An equation that matches the table include the following: y = x + 5.
How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):
y - y₁ = m(x - x₁)
Where:
m represent the slope.x and y represent the points.First of all, we would determine the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (6 - 5)/(1 - 0)
Slope (m) = 1/1
Slope (m) = 1.
At data point (0, 5) and a slope of 1/, a linear equation in slope-intercept form for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 5 = 1(x - 0)
y - 5 = x

How old is a bone fragment if the proportion of carbon-14 remaining is 25%? A. 2865 a B. 5760 a C. 11 460 a D. 17 190 a
Answer:
In order of the questions asked, the answers are, C, D, A, C
Step-by-step explanation:
After three half-lives have elapsed, 12.5% of the original nuclide remains, so the answer is C.
if 17 % is daughter nuclide, then 83% is parent nuclide, so , the answer is D
the isotope for dating organic remains is A. carbon-14
for 25% of original, 2 half-lives must have passed, so we get (2)(5730) = 11460

Angle t has a measure between 0° and 360° and is coterminal with a â€""710° angle. what is the measure of angle t? 5° 10° 15° 20°
Angle t has a measure between 0° and 360° and is coterminal with a â€""710° angle. Therefore, the measure of
angle t is 10 degrees.
The measure of angle t that is coterminal with a −710° angle is 10°.
Coterminal angles are those angles that have a terminal side that coincides with each other when both are placed in
standard position, which means their initial sides are placed on the positive x-axis.
They are separated by a multiple of 360 degrees. Because 710 degrees are 360 degrees more than a full circle (i.e.,
710 - 360 = 350), the angle t that is coterminal with -710 degrees is 350 degrees.
Since the angle's degree measure should be between 0 degrees and 360 degrees, we need to subtract 360 degrees
from 350 degrees.
350 degrees - 360 degrees = -10 degrees
To express the angle in positive degree measures, we need to add 360 degrees to the angle.
360 degrees - 10 degrees = 350 degrees
Therefore, the measure of angle t is 10 degrees.

Which ordered pair is a solution of the equation y+1=3(x-4)
Step-by-step explanation:
When x = 4 and y = -1,
(-1) + 1 = 3(4 - 4) = 0.
Hence (4, -1) is an ordered pair.
When x = 5 and y = 2,
(2) + 1 = 3(5 - 4) = 3.
Hence (5, 2) is an ordered pair.

A pharmacist mixed 800 mg of a liquid drug (sg = 0.8) in enough liquid to prepare 2 liters of a final product. what is the ratio strength of the final product?
The ratio strength of the final product is 1:0.4.
What is ratio strength?One technique to indicate concentration is through ratio strength, which uses a ratio to characterize drug concentration. In this context, concentration is defined as the quantity of a solute that makes up one unit in the whole volume of a solution or combination. You should be an expert in ratio strength calculations as a pharmacy student. Ratio strength uses a ratio to describe the medication concentration. So, what it implies is, you have one unit of solute contained in the complete amount of preparation and so generally your ratio strength is expressed as one is to something. In the case of a weight-in-weight, volume-in-volume, or weight-in-volume situation, you would interpret a ratio of 1:2,000 differently.

An open-top container is to be made from a 13-inch by 48-inch piece of plastic by removing a square from each corner of the plastic and folding up the flaps on each side. What size square should be cut out of each corner to get a container with the maximum volume?
To maximize the volume of an open-top container made from a 13-inch by 48-inch piece of plastic, you need to determine the optimal size of the squares to be cut out from each corner. Let 'x' be the side length of the square removed from each corner. After cutting, the dimensions of the container will be:
- Length: 48 - 2x
- Width: 13 - 2x
- Height: x
The volume of the container can be calculated using the formula: V = L * W * H. the dimensions, we get:
V(x) = (48 - 2x)(13 - 2x)(x)
To find the maximum volume, we need to identify the value of 'x' that maximizes V(x). This can be achieved using calculus, by finding the critical points where the derivative of the function V(x) is zero or undefined.
Differentiating V(x) with respect to x and setting the derivative equal to zero, we can solve for the optimal value of 'x'. After performing these calculations, we find that the optimal size of the square to be cut out from each corner is approximately 1.52 inches. By removing 1.52-inch squares from each corner and folding up the flaps, the open-top container will have the maximum volume.

Find the dual for the following linear programming problem: (i) Maximize Z= 3x + 4y + 5z Subject to: X + 2y + z ≤ 10 7x + 3y + 9z ≤ 12 X, Y, 2 ≥ 0. [2 MARKS] (ii) Minimize Z = y1 + 2y2 Subject to: 3yi + 4y2 > 5 2y1 + 6y2 ≥ 6 Yi + y2 ≥ 2
The dual for the given linear programming problems are as follows:
(i) Minimize Z' = 10a + 12b Subject to: a + 7b ≥ 3 2a + 3b ≥ 4 a + 9b ≥ 5 a, b ≥ 0.
(ii) Maximize Z' = 5a + 6b + 2c Subject to: 3a + 2b + c ≤ 1 4a + 6b + c ≤ 2 a + b ≤ 0 a, b, c ≥ 0.
What are the dual formulations for the given linear programming problems?In the first problem, we have a maximization problem with three variables (x, y, z) and two constraints. The dual formulation involves minimizing a new objective function with two variables (a, b) and four constraints. The coefficients of the variables and the constraints are transformed according to the rules of duality.
The primal problem is:
Maximize Z = 3x + 4y + 5z
Subject to:
x + 2y + z ≤ 10
7x + 3y + 9z ≤ 12
x, y, z ≥ 0
To find the dual, we introduce the dual variables a and b for the constraints:
Minimize Z' = 10a + 12b
Subject to:
a + 7b ≥ 3
2a + 3b ≥ 4
a + 9b ≥ 5
a, b ≥ 0
In the second problem, we have a minimization problem with two variables (y1, y2) and three constraints. The dual formulation requires maximizing a new objective function with three variables (a, b, c) and four constraints. Again, the coefficients and constraints are transformed accordingly.
The primal problem is:
Minimize Z = y1 + 2y2
Subject to:
3y1 + 4y2 > 5
2y1 + 6y2 ≥ 6
y1 + y2 ≥ 2
To find the dual, we introduce the dual variables a, b, and c for the constraints:
Maximize Z' = 5a + 6b + 2c
Subject to:
3a + 2b + c ≤ 1
4a + 6b + c ≤ 2
a + b ≤ 0
a, b, c ≥ 0
The duality principle in linear programming allows us to find a lower bound (for maximization) or an upper bound (for minimization) on the optimal objective value by solving the dual problem. It provides useful insights into the relationships between the primal and dual variables, as well as the economic interpretation of the problem.

The variable a is an array of integers, and the variable p is a pointer to the first element of the array.
The expression *(p + 3) is the value of the element of the array that is 3 elements after the element that p points to.
Since p points to the first element of the array, the expression *(p + 3) is the value of the fourth element of the array, which is 4.
Therefore, the value of the expression is 4.
Here is a breakdown of the code:
