Answer:
C. 1/(x^2 +1) > 0
Step-by-step explanation:
The cube of a negative number is negative, eliminating choices B and D for certain negative values of x.
1/x^2 is undefined for x=0, so cannot be compared to zero.
The value 1/(x^2+1) is positive everywhere, so that is the expression you're looking for.
1/(x^2 +1) > 0

Answers
Answer:
1/4 or or 0.25
1Step-by-step explanation:
just do 2.75 divided by 11 and you get your answer
At rate 0.25 inch per hour the candle burn.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
A 2 3/4 inch candle burns down in 11 hours.
Now,
Since, A 2 3/4 inch candle burns down in 11 hours.
Hence, The rate in which the candle burn, in inches per hour is;
= [tex]2 \frac{3}{4}[/tex] ÷ [tex]11[/tex]
= 11/4 ÷ 11
= 11/4 x 1/11
= 1/4 inches per hour.
Thus, At rate 0.25 inch per hour the candle burn.

Frieda and three of her friends decide to go canoeing. They each rent a life preserver for $12.75. They split the cost of the canoe. If each person pays $23.75, how much did the canoe cost?
Answers
Answer:
The canoe cost $44
Step-by-step explanation:
There are 4 friends that went canoeing. Each one of them spent a total of $23.75 including $12.75 for the rent of a life preserver, and for one-fourth of the canoes cost, assuming they split the total cost of the canoe.
From the $23.75, we must subtract the $12.75 that the life preserver cost:
$23.75-$12.75 = $11
Those $11 were the individual contribution to the cost of the canoe. Since there were 4 friends, the canoe cost 4*$11 = $44
The canoe cost $44

In the game of roulette, a player can place a $ bet on the number and have a probability of winning. If the metal ball lands on , the player gets to keep the $ paid to play the game and the player is awarded an additional $. Otherwise, the player is awarded nothing and the casino takes the player's $. What is the expected value of the game to the player? If you played the game 1000 times, how much would you expect to lose?
Answers
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
The expected amount to be lost is 0.5263 cents per game
b
The expected amount to be lost is
[tex]P = \$ 526 .3 [/tex]
Step-by-step explanation:
From the question we are told that
The probability of winning is [tex]p = \frac{1}{38} = 0.0263[/tex]
Generally the probability of losing is mathematically evaluated as
[tex]q = 1-p [/tex]
=> [tex]q = 1-0.0263 [/tex]
=> [tex]q = 0.9737[/tex]
Generally the expected value is mathematically represented as
[tex]E(X) = \sum x_i * P(x_i)[/tex]
Here [tex]x_i[/tex] is a discrete variable (i.e it is a countable ) are outcomes of the player winning and the player losing
So
[tex]E(X) = x_1 * P(x_1) + x_2 * P(x_2) [/tex]
Now the outcome of winning is making $350 so
[tex]x_1 = \$ 350[/tex]
the outcome of losing is losing $10 so
[tex]x_2 = - \$10[/tex]
So
[tex]E(X) = 350* 0.0263 -10 * 0.9737 [/tex]
[tex]E(X) = -0.5263 [/tex]
hence the expected amount to be lost is 0.5263 cents per game
If you played the game 1000 times, the amount that is expected to be lost is
[tex]P = 1000 * -0.5263[/tex]
=> [tex]P = -\$ 526 .3 [/tex]
Hence the expected amount to be lost is
[tex]P = \$ 526 .3 [/tex]
Which sequence of transformations creates a similar but not congruent triangle? (5 points)
A
Rotation and reflection
B
Reflection and translation
C
Translation and rotation
D
Dilation and reflection
Answers
Answer:
D. Dilation and reflection
Step-by-step explanation:
There are 4 main types of transformations, rotation, reflection, translation, and dilation. 3 of these transformations are defined as rigid, rigid means that the transformation preserves angles and distance between points. If these aspects are preserved than the image is congruent. The only non-rigid transformation listed is dilation, therefore D must be correct.

The sum of three consecutive rven integers is 72. Let x represent the first integer, x+2 represent the srcond integer, and x+ 4 represent the third which equation can be used to find the first integer
Answers
Given parameters:
First term of the sequence = x
Second term = x + 2
Third term = x + 4
Sum of the first three terms = 72
Unknown:
First term of the sequence = ?
Solution:
The sum of the first three terms is unknown;
(x) + (x + 2) + (x + 4) = 72
Solve for x;
x + x + 2 + x + 4 = 72
3x + 6 = 72
3x = 72 - 6
3x = 66
x = [tex]\frac{66}{3}[/tex] = 22
The first term of the sequence is 22
