Find the three digit numbers which have the the following properties: all three digits are different, the first digit is the square of the second digit and the third digit is one more than twice the second digit.
Answer:
Step-by-step explanation:
1^2 = 1 This one is impossible. The digits have to be different.
2^2 = 4
3^2 = 9
so the first two digits can either be
4 and 2
9 and 3
The third clue is the one that decides. The third digit is odd and and 1 more than twice the second
The third digit can be 2 * 2 + 1 = 5 or 2*3 + 1 = 7. There is no way to choose between them.
So the answer is either 425 or 937. We cannot decide which. If there is another clue that will break the log jam, post it and I'll come back.
These are the only two answers possible. If the second digit is more than 3 then the first digit is no longer a single digit. It is more than 9.

A television network is about to telecast a new television show. Before a show is launched, the network airs a pilot episode and receives a report assessing favorable or unfavorable viewer response. In the past, 60% of the network's shows have received a favorable response from viewers, and 40% have received an unfavorable response. If 50% of the network’s shows have received a favorable response and have been successful, and 30% of the network’s shows have received an unfavorable response and have been successful, what is the probability that this new show will be successful if it receives a favorable response? A. 0.41 B. 0.53 C. 0.67 D. 0.70 E. 0.83
Answer:
.83
Step-by-step explanation:
If you take 100 shows 60 shows got favorable response and in that 50 shows were successful.
So probability for a show to be successful if it got a favorable response is = 50/60 = 0.83

Jill has 120 feet of fencing to use for her horse paddock. To increase the area she can enclose, she plans on using the side of the barn as one side of her paddock as shown below. Determine which equation can be used to find the dimensions of the horse paddock when the area is 1,800 square feet. Let x represent the width of the paddock.
Answer:
D) -2x²+120=1800
Step-by-step explanation:
area=l*w
the area is 1800 (given)
the length is x (given)
the width would be 120-2x (120 feet of fencing minus the two lengths)
SO
1800=(x)(120-2x)
1800=120x-2x²
1800=-2x²+120
-2x²+120=1800
So the answer is D
The equation representing the area of the horse paddock is -2x² + 120x = 1800. The correct option is (D).
What is a rectangle?A rectangle is a type of parallelogram having equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The area of a rectangle can be found by taking the product of its length and breadth.
Given that,
The total length of the fence is 120 feet.
And, the area enclosed is 1800 square feet.
As per the given question, the expression for the length of fence is as below,
2x + l = 120
=> l = 120 - 2x
Since the horse paddock is in the shape of a rectangle, its area can be written as,
x(120 - 2x) = 1800
=> 120x - 2x² = 1800
=> -2x² + 120x = 1800
Hence, the equation that can be used to find the dimensions of the horse paddock is given as -2x² + 120x = 1800.

EXAMPLE 10 Show that the points (a, a),(-a, - a) and (-3a, 3a) are the vertices of an equilateral triangle. Also find its area.
Answer:
The triangle is not equilateral.
Step-by-step explanation:
Distance formula:
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Distance from (a, a) to (-a, -a):
[tex] d_1 = \sqrt{(-a - a)^2 + (-a - a)^2} [/tex]
[tex] d_1 = \sqrt{(-2a)^2 + (-2a)^2} [/tex]
[tex] d_1 = \sqrt{8a^2} [/tex]
Distance from (-a, -a) to (-3a, 3a):
[tex] d_2 = \sqrt{(-3a - (-a))^2 + (3a - (-a))^2} [/tex]
[tex] d_2 = \sqrt{(-2a)^2 + (4a)^2} [/tex]
[tex] d_2 = \sqrt{20a^2} [/tex]
Distance from (-3a, 3a) to (a, a):
[tex]d_3 = \sqrt{(-3a - a)^2 + (3a - a)^2}[/tex]
[tex]d_3 = \sqrt{(-4a)^2 + (2a)^2}[/tex]
[tex]d_3 = \sqrt{20a^2}[/tex]
The three sides do not have the same length, so the triangle is not equilateral.
ANSWER ASAP THANK youuu
Answer:
A
Step-by-step explanation:
● -7x > 21
Divide both sides by 7
● -7x/7 > 21/7
● -x > 3
Multiply both sides by -1 and switch the sign since you have multiplied by a negative number.
● x < -3
The representation is A since -3 is represented by an empty dot ○ wich means it's out the solutions
The solution to the given inequality -7x/7 > 21/7 is x < -3 which is the correct answer that would be option (A).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
The inequality is given in the question
⇒ -7x > 21
Divide both sides by 7 both sides of the above inequality
⇒ -7x/7 > 21/7
⇒ -x > 3
Multiply both sides by -1 and because we multiplied by a negative quantity, flip the sign.
⇒ x < -3
The representation is A because -3 is represented by an empty dot which shows the solution of the graph.
The required graph has been attached which represents the solution to the given inequality -7x/7 > 21/7 is x < -3
Hence, the correct answer would be an option (A).

Answer:
B. 255 m
Step-by-step explanation:
use similar triangle
L / 60 = 85 / 20
L = (85 * 60) / 20
L = 255 m
The distance across the lake will be 255 meters. Then the correct option is B.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
If the two triangles are similar, the ratio of the corresponding sides will be constant.
In an isosceles triangle, two angles and their opposite sides are equal.
The dimensions of the first triangle are L, 85, and y. And the dimensions of the second triangle are 60, 20, and x.
It is given that the triangles are similar.
Then the ratio of their corresponding sides will be
L / 60 = 85 / 20 = x / y
From first two terms, then the equation will be
L / 60 = 85 / 20
L / 60 = 4.25
L = 4.25 x 60
L = 255 m
The distance across the lake will be 255 meters.
Then the correct option is B.

In comparing two distributions, which attribute would you not compare?
A. Shape
B. Center
C. Marginal frequency
D. Spread
Answer:
The correct option is;
C. Marginal frequency
Step-by-step explanation:
The objective of comparison of two distributions is to check the significant difference from each other
The general measures used to compare the difference between distributions are the measures of centers such as the mean, the measures of spread such as the standard deviation and the shape of the compared distribution curves
Marginal frequencies are the values found in the total row and total column portion of a two way frequency distribution table
The marginal frequency is used to calculate the marginal relative frequency
The values of the marginal frequency, which is a sum, does not characterize the details of a distribution to a large extent.

What is the solution of −83 = b4? A. b = –332 B. b = –87 C. b = –79 D. b = –20.75
Answer:
D; b = -20.75
Step-by-step explanation:
Here in this question, we want to find solution to the given linear equation.
The linear equation is;
-83 = b4
Now, to find the value of b, we will need to divide both sides by its coefficient.
Looking at the question, the coefficient of b is 4
Mathematically, that would be :
-83/4 = b4/4
b = -83/4
b = -20.75
Answer:
b = -20.75
Step-by-step explanation:
Given:
-83 = b4
It can also be written as
-83 = 4b
divide both sides by the coefficient of b which is 4
-83 / 4 = 4b / 4
-20.75 = b
Therefore,
b = -20.75
Check:
-83 = b4
-83 = -20.75(4)
-83 = -83

We know that a^ b^ c = a^ ( b*c)

y-3x=13 solve for y ♀️
Answer:
y = 3x+13
Step-by-step explanation:
y-3x=13
Add 3x to each side
y-3x+3x=3x+13
y = 3x+13
The value of y for the given equation y - 3x = 13 is calculated to be y = 3x + 13.
Given that:
y - 3x = 13
It is required to find the value of y.
In order to find the value of y, the equation has to be solved in such a way that y has to be kept on one side.
Consider:
y - 3x = 13
Add 3x on both sides.
y - 3x + 3x = 13 + 3x
y = 13 + 3x
Hence, the value of y is 13 + 3x.
