Help !!!! Thank you!!!!
Answer:
Option (G)
Step-by-step explanation:
Volume of the real cane = 96 in³
Volume of the model of a can = 12 in³
Volume scale factor = \(\frac{\text{Volume of the model}}{\text{Volume of the real can}}\)
= \(\frac{12}{96}\)
\(=\frac{1}{8}\)
Scale factor of the model = \(\sqrt[3]{\text{Volume scale factor}}\)
\(=\sqrt[3]{\frac{1}{8}}\)
\(=\frac{1}{2}\)
Therefore, scale factor of the model of a can = \(\frac{1}{2}\) ≈ 1 : 2
Option (G) will be the correct option.
Find the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0)
The value of x that makes the line containing (1,2) and (5,3) perpendicular to the line containing (x,4) and (3,0) is x = 2.
To determine the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0), we need to find the slope of both lines and apply the concept of perpendicular lines.
The slope of a line can be found using the formula:
slope = (change in y) / (change in x)
For the line containing (1,2) and (5,3), the slope is:
slope1 = (3 - 2) / (5 - 1) = 1 / 4
To find the slope of the line containing (x,4) and (3,0), we use the same formula:
slope2 = (0 - 4) / (3 - x) = -4 / (3 - x)
Perpendicular lines have slopes that are negative reciprocals of each other. In other words, if the slope of one line is m, then the slope of a line perpendicular to it is -1/m.
So, we can set up the equation:
-1 / (1/4) = -4 / (3 - x)
Simplifying this equation:
-4 = -4 / (3 - x)
To remove the fraction, we can multiply both sides by (3 - x):
-4(3 - x) = -4
Expanding and simplifying:
-12 + 4x = -4
Adding 12 to both sides:
4x = 8
Dividing both sides by 4:
x = 2

The probability that at least one of the dice lands on an even number is 15/16 or approximately 0.938.
What is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen. The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
We can solve this problem by finding the probability that all four dice land on odd numbers and then subtracting this probability from 1 to get the probability that at least one of the dice lands on an even number.
The probability that one dice lands on an odd number is 3/6 = 1/2, and the probability that all four dice land on odd numbers is:
(1/2) × (1/2) × (1/2) × (1/2) = 1/16
Therefore, the probability that at least one of the dice lands on an even number is:
1 - 1/16 = 15/16
So the probability that at least one of the dice lands on an even number is 15/16 or approximately 0.938.

Determine whether the ordered pair is a solution to the given system of
equations.
1) (1,5);
-5m +6n = 25
-7m +8n = 33
2) (-2, 0);
8x-3y=-16
50 = -9x - 2y
1. The ordered pair (1, 5) is a solution to the system of equations.
2. The ordered pair (-2, 0) is NOT a solution to the system of equations.
How did we arrive at the assertions?To determine if the ordered pair (1, 5) is a solution to the system of equations, we substitute the values into the equations and see if they hold true.
-5(1) + 6(5) = 25
25 = 25 (holds true)
-7(1) + 8(5) = 33
33 = 33 (holds true)
Since both equations hold true for the values of m=1 and n=5, we can conclude that the ordered pair (1, 5) is a solution to the system of equations.
To determine if the ordered pair (-2, 0) is a solution to the system of equations, we substitute the values into the equations and see if they hold true.
8(-2) - 3(0) = -16
-16 = -16 (holds true)
-9(-2) - 2(0) = 50
4 ≠ 50 (does not hold true)
Since one of the equations does not hold true for the values of x=-2 and y=0, we can conclude that the ordered pair (-2, 0) is NOT a solution to the system of equations.

We will assume that the smiling times of an eight-week-old baby, in seconds, follow a uniform distribution between zero and 23 seconds, inclusive. What is the probability that a randomly chosen eight-week-old baby smiles between two and 18 seconds
Answer:
P ( 2<x<18) = 16/23
Step-by-step explanation:
Since it is a uniform distribution the f(x) is given by
f(x) = 1/b-a a ≤x ≤b [0,23]
f(x) = 1/23-0 = 1/23
Now we have to find the probability that a randomly chosen eight-week-old baby smiles between two and 18 seconds
P ( 2<x<18) = base * height
= ( b-a) * 1/ b-a
= 18-2 *1/23
=16/23
The uniform distribution is called rectangular distribution because its total probability is confined to a rectangular region with base equal to (b-a) and height (1/b-a).

A wire that is centimeters long is shown below.
The wire is cut into two pieces, and each piece is bent and formed into the shape of a square.
Using properties of square,
a. Equation for total area = 2x² - 16x + 64
b. Area will be minimum for the value of x = 0
c. Minimum area will be 64cm².
Define a square?With four equal sides, a square is a quadrilateral. There are numerous square-shaped objects in our immediate environment. The equal sides and 90° internal angles of each square form serve as indicators of its identity.
Total length of wire = 32cm.
Now side of one square is given as x.
Perimeter of big square will be = 4x.
Now perimeter of small square = 32- 4x.
Side of small square = (32-4x)/4

Area of big square = x × x
= x².
Area of small square = (8-x) ².
Now Total area, A(x) = x² + (8-x) ²
= x² + 64 + x² - 16x

Answer:
d. 5. 1 ≤ d ≤ 2
e. 4. t ≥ 5
f. 1. -z < 4
Step-by-step explanation:
d. d is between 2 and 1
The statement "d is between 2 and 1" means that d is greater than 1 and less than 2. We can represent this using the inequality 1 < d < 2. However, the answer choices do not match this exact form of inequality. To rephrase the inequality in a way that matches the answer choices, we can use the logical "and" operator to combine two inequalities: d is greater than or equal to 1, and d is less than or equal to 2. This gives us the inequality 1 ≤ d ≤ 2, which is answer choice 5.
e. t is not less than 5
The statement "t is not less than 5" means that t is greater than or equal to 5. This can be represented using the inequality t ≥ 5, which is answer choice 4.
f. The negative of z is not greater than 4
The statement "the negative of z is not greater than 4" means that -z is less than or equal to 4. We can represent this using the inequality -z ≤ 4, which is answer choice 2. However, the question does not include an answer choice for -z < 4, which is also true based on the statement.
