In linear equation, the missing value is a 16.
According to the statement
We have to find that the value of the linear equation.
So, For this purpose, we know that the
The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
From the given information:
It is given that:
The equation shown includes a missing value.
-2(2x - ?) + 1 = 17 - 4x
Applying the distributive property:
-4x + ? + 1 = 17 - 4x
? + 1 = 17
There aren't any values that the equation has only 1 solution or unique solutions.
For no solution the missing value are often anything except 16
? + 1 = 17
? = 17 - 1
? = 16
Thus, there aren't any values that the equation has just one solution for no solution the missing value are often anything except 16.
So,In linear equation, the missing value is a 16.

The price of Stock A at 9 A.M. was $15.03. Since then, the price has been increasing at the rate of $0.05 each hour. At noon the price of Stock B was $15.53. It begins to decrease at the rate of $
0.14 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
After 1.842 hours the price of Stock A and Stock B will be the same using a set of linear equations.
A grouping of one or more linear equations containing the same variables is known as a system of linear equations.
For Stock A :
The initial price = $15.03
The rate of increase = $0.05
For Stock B :
The rate of decrease = $15.53
The rate of decrease per hour = $0.13
Then the price of stock A at noon will be:
$ 15.03 + $ (0.05 × 3) = $ 15.03 + $ 0.15 = $15.18
The period of time during which the stock price will remain constant:
15.18 + 0.05t = 15.53 - 0.14t
Simplifying the terms we get,
0.05t + 0.14t = 15.53 - 15.18
0.19t = 0.35
t = (0.35 ÷ 0.19) hours
t = 1.842 hours
Therefore, the stocks will be of equal price after 1.842 hours.

Nathan is planning to ride his bike for 24 minutes if he rides at a rate of 5 miles per hour how far will he travel
The distance that Nathan can ride his bike is 2 miles.
What is the distance Nathan can ride?The rate is the total distance per time. Rate is determined by dividing the total distance travelled by the total time travelled.
Rate = total distance / total time.
Distance = rate x time
The rate is in miles per hour while the time given is in minutes. Thus, minutes has to be changed to hour. To do this, divide 24 minutes by 60.
60 minutes = 1 hour
24/ 60 = 2/5
Distance = 2/5 x 5= 2 miles

Use PEMDAS to determine order of operations in a mathematical expression
The order of operations is
P = parentheses
E = exponent
M = multiplication
D == division
A = addition
S = subtraction
Note that multiplication and division have the same priority and we go from left to right that case. Because it does not affect the answer.
So 12 ÷ 4 x 6 = 12 x 6 ÷ 4
Same for addition and subtraction - same priority
Using PEMDAS
(9 - 1) is executed first giving 8
The expression becomes 8 + 8 ÷ 4
Next division is performed so 8 ÷ 4 is executed giving 2 as the answer
Finally 8 + 2 is executed giving 10

Write an equation for the parabola in vertex form whose vertex is at (2, 3) and passes through (0, 2).
The equation of the parabola in discuss such that the parabola has a vertex at (2, 3) and passes through (0, 2) is; y = (-1/4) (x - 2)² + 3.
What is the equation of.the parabola in discuss whose vertex is at (2, 3) and passes through (0, 2)?It follows from the task content that the equation of the parabola whose vertex is at (2, 3) and passes through (0, 2) is to be determined.
Since, the vertex form equation of a parabola is;
y = a (x-h)² + k
where the vertex is; (h, k) which is (2, 3) in this scenario.
Therefore, we have;
y = a (x - 2)² + 3
Ultimately, to find the value of a; substitute; x = 0 and y = 2 from the point (0,2) into the equation;
2 = a (0-2)² +3
-1 = 4a
a = -1/4.
Ultimately, the equation of the parabola as required in the task content is;

At a constant temperature, the atmospheric pressure p in pascals is given by the formula p=101.3 e⁻⁰.⁰⁰¹h , where h is the altitude in meters. What is p at an altitude of 500 m ?
At an altitude of 500 meters, the atmospheric pressure (p) will be 61.46 pascals.
The exponential constant, denoted by the symbol e, is an essential mathematical constant. Its value is approximately equal to 2.718. This value occurs very frequently in mathematics when it is used to model physical and economic phenomena.
Here, we are given an exponential function- p = 101.3[tex]e^{-0.001h}[/tex]
where p = atmospheric pressure in pascals
h = altitude in meters.
If the altitude is 500m
h = 500
Then,
p = 101.3 [tex]e^{-0.001 * 500}[/tex]p
= 101.3 [tex]e^{-0.5}[/tex]p
= 101.3/ [tex]e^{-0.5}[/tex]p
= 101.3/ 1.648p

Christmas tree lights are used not only for christmas trees, but sometimes to decorate college dorm rooms. Suppose that a string has 20 light bulbs. These lights are all wired in series, so that if one light bulb fails, the whole string fails. The probability that any one light fails is 0. 2. Each of the individual lights are independent of each other. What is the probability that the string will not fail?.
If a string has 20 light bulbs and these lights are all wired in series, so that if one light bulb fails, the whole string fails and the probability that any one light fails is 0.2 and each of the individual lights are independent of each other, then the probability that the string will not fail is 0.0115.
Probability in mathematics deals with the likelihood of an event to take place.
The probability that the string will not fail refers to when all 20 bulbs will not fail. As given in the conditions, each of the individual lights are independent of the other. Therefore;
the probability that any one of the lights will not fail is:
1 - probability that any one light fails = 1 - 0.2 = 0.8
And we need all 20 to be complete. The unity of events is a product of probabilities. Therefore the probability that the string will not fail is:
P = 0.8^20
P = 0.0115
Hence 0.0115 is the probability that the string will not fail.
