A student is solving the problem X to the power of 2+10x+ __=16+ __ my method of completing the square. What number should the student add to both sides?
A) 4
B)5
C) 25
D) 16
Answer: C) 25
Step-by-step explanation:
x²+10x+ __=16+ __

48 and 15 both go into 3,
15÷3= 5
48÷3=16
So then answer would be 5/16 sq ft

Answer:
h = 79 m
Step-by-step explanation:
The length of the string, H = 125 m
The kite forms 39° angle.
We need to find the height of the kite. Let it is h. We can find it using trigonometry i.e.
[tex]\sin\theta=\dfrac{P}{H}[/tex]
Where
P is perpendicular and H is Hypotenuse
So,
[tex]\sin\theta=\dfrac{h}{H}\\\\h=H\times \sin\theta\\\\h=125\times \sin(39)\\\\h=78.66\ m[/tex]
or
h = 79 m
So, the kite is flying at a height of 79 m.

The value of the expression 3 + 5³ × 5 + 1 will be 629.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
According to the PEMDAS rule, the operation should be performed in the order of the computation or the parentheses, whichever comes first.
The sum of three and five to the third power times five plus one will be written mathematically and will be
⇒ 3 + 5³ × 5 + 1
Simplify the expression, then the value of the expression will be
⇒ 3 + 125 × 5 + 1
⇒ 3 + 625 + 1
⇒ 629
The value of the expression 3 + 5³ × 5 + 1 will be 629.

A roulette wheel consists of 18 red slots, 18 black slots, and 2 green slots. A player can wager $1 that a marble will land in a red slot, in which case the player would gain a $1. If the marble lands in a slot that isn't red, then the player loses their $1 wager. Let X represent the player's gain from a random $1 wager on red. Here's the probability distribution of X along with summary statistics:
Lose Win
X = gain (S) -1 1
Р(X) 20/38 18/38
Мean: Ax-$0.05
Standard deviation: ax$1.00
Suppose a player decides to wager $5 instead of winning $5.
Let Z represent the player's gain from a random $5 wager on red. possible outcomes become either losing or , so
What are the mean and standard deviation of Z? dollars?
Answer:
-$0.26 ; $5
Step-by-step explanation:
Given that :
____________ Lose ______ Win
X =$1 _______ - $1 ________ $1
P(X) _______20/ 38 _____ 18/38
Mean, Ux = - $0.05
Standard deviation, σx = $1.00
If the wager is $5 instead of $1
Mean = Σx*p(x)
Mean = (-5 * 20/38) + (5 * 18/38)
Mean = - 2.6315789 + 2.3684210
Mean (μ) = −0.26
Standard deviation :
Sqrt(Σx²p(x) - μ²)
[(-5^2)*(20/38) + (5^2)*(18/38)] - (-0.26^2)
(13.157894 + 11.842105) - 0.0676
= 24.999999 - 0.0676
= sqrt(24.932399)
= 4.9932353
= 5

According to the DuPont 2012 Global Automotive Color Popularity Report, 23% of all cars manufactured in 2012 were white. In a random sample of 100 cars parked in long-term parking at Philadelphia International Airport, 19% of the cars were white. Identify the underlined values as parameters or statistics and give the appropriate variable. Spell out phat, x-bar, mu, sigma for the variable names. Which of the following statements istrue?
a. 19% and 23% are parameters, 100 is a statistic.
b. 23% is a parameter, 19% is a statistic.
c. 23% is a statistic, 19% is a parameter.
d. 19% and 23% are statistics, 100 is neither a parameter nor a statistic.
e. 19%, 23%, and 100 are all statistics.
Answer:
b. 23% is a parameter, 19% is a statistic.
Step-by-step explanation:
If the value is from a population, it is a parameter.
Otherwise, if the value is from a sample, it is a statistic.
23% of all cars manufactured in 2012 were white.
This is from the population(all cars), so 23% is a parameter.
In a random sample of 100 cars parked in long-term parking at Philadelphia International Airport, 19% of the cars were white.
100 is the size of the sample, which is neither a parameter, nor a statistic.
19% is from the sample of 100, so it is a statistic.
The correct answer is given by option b.

300
it is given that 12% were rotten
12% = 36
then let total no of apple be X
then , x*12/100 = 36
x= 36*100/12
x = 300

answer to the nearest tenth if necessary. Figures are not drawn to scale
Answer:
Step-by-step explanation:
Remark
Try to make sure that when you set up your proportion, that the side you are trying to find is the numerator. Then all you have to do is multiply both sides by the numerator underneath the unknown side.
Equation
x / 11 = 27 / 7
Solution
Multiply both sides by 11
11 * x / 11 = 27 * 11 / 7
x = 297 / 7
