The required expression equivalent to the given expression is 3²² .
An expression in mathematics is said to be algebraic if it was constructed using integer variables, constants, and algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)
However, transcendental numbers like such and e are not algebraic because they are not created from integer constants and algebraic operations.While the definition of e necessitates an infinite number of algebraic operations, the generation of is frequently expressed as a geometric expression.If an expression can be reduced to a reasonable fraction using the features of arithmetic operations, it is said to be rational (commutative properties and associative properties of addition and multiplication, distributive property and rules for the operations on the fractions).Given : the expression of the form ( 3 ⁴ ) ⁶ ÷ 3²
Simplifying we get:
= ( 3 ⁴ ) ⁶ ÷ 3²
= 3⁽²⁴⁻²⁾
= 3²²
Therefore the required expression equivalent to the given expression is

9 + 2 x 3 = 11 x 3 = 33
How would you write this problem with the multiplication first?
The error in the solution is adding 9 and 2 before the multiplication and the new expression is (2 x 3) + 9
The description of the error?The equation and the steps are given as
9 + 2 x 3 = 11 x 3 = 33
The above solution is incorrect
This is so because the product has a higher order of precedence
So, it must be evaluated first
So, the correct solution is
9 + 2 x 3 = 9 + 6 = 15
To rewrite the expression such that the product is done first, we introduce the use of brackets
So, we have

Heights of 10-year old's, regardless of gender, closely follow a normal distribution with mean 55 inches and standard deviation 6 inches.
(a). The height requirement for Batman the Ride is 54 inches. What percent of 10 year old's cannot go on this ride?
(b). Suppose there are four ten year olds. What is the chance that at least two of them will be able to ride Batman the Ride?
(c). Suppose you work at the park to help them better understand their customers demoghraphics, and you are counting people as they enter the park. What is the chance that the first 10 year old you see who can ride Batman the Ride is the 3rd 10 year old who enters the park?
(d). What is the chance that the 5th 10 year old you see who can ride Batman the Ride is the 12th 10 year old who enters the park?
Using the normal distribution and the binomial distribution, it is found that:
a) 43.25% of 10 year old's cannot go on this ride.
b) There is a 0.7814 = 78.14% probability that at least two of them will be able to ride Batman the Ride.
c) There is a 0.1062 = 10.62% probability that the first 10 year old you see who can ride Batman the Ride is the 3rd 10 year old who enters the park.
d) There is a 0.0834 = 8.34% probability that the 5th 10 year old you see who can ride Batman the Ride is the 12th 10 year old who enters the park.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable that has mean given by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is above(in case the score is positive) or below(in case the score is negative) the mean. From the z-score table, the p-value associated with the z-score is found, which represents the percentile of the measure X.In the context of this problem, the mean and the standard deviation are given as follows:
[tex]\mu = 55, \sigma = 6[/tex]
For item a, the proportion is the p-value of Z when X = 54, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (54 - 55)/6
Z = -0.17.
Z = -0.17 has a p-value of 0.4325.
Hence the percentage is of 43.25%.
What is the binomial distribution formula?The formula for the probability of x successes is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are given by:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.For item b, the parameters of the binomial distribution are given as follows:
p = 0.5675, n = 4.
Hence:
P(X = 2) = 6 x (0.5675)² x (0.4325)² = 0.3615.P(X = 3) = 4 x (0.5675)³ x (0.4325)¹ = 0.3162.P(X = 4) = (0.5675)^4 = 0.1037.Hence:
P(X >= 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.3615 + 0.3162 + 0.1037 = 0.7814.
Which is the probability.
For item c, the probability is given as follows:
p x P(X = 0 with n = 2).
Hence:
p = 0.5675 x (0.4325)² = 0.1062.
For item d, the probability is given as follows:
p x P(X = 4 with n = 11). (inverse binomial).
Hence:
0.5675 x (11!)/(5! x 6!) x (0.5675)^4 x (0.4375)^7 = 0.0834.

The most appropriate choice for speed will be given by
Speed of the car of Lewis family = 38 miles/hours
What is speed?
Distance travelled by an object per unit of time is called speed.
If d is the distance travelled and t is the time taken, then speed is calculated by-
Speed = [tex]\frac{d}{t}[/tex]
Here, speed is a scalar as the direction is not taken into account.
Distance drove by Lewis family to the river = 45.6 miles

what does this mean 3|-3| the whole |-3| thing I'm confused please help
|-3| means "the absolute value of 3", which is a way of saying how far away from zero the number -3 is on the number line.
The definition of absolute value goes like this:
[tex]|x| = \begin{cases} x & \text{if } x \ge 0 \\ -x & \text{if } x < 0 \end{cases}[/tex]
In other words, if the number [tex]x[/tex] inside the absolute value bars is already positive or zero, we leave it alone. If instead [tex]x[/tex] is negative, we multiply it by -1 to recover the positive version of that number.
Since -3 is negative, it follows that |-3| = -(-3) = 3. So the expression 3 |-3| is equivalent to 3 • 3 = 3² = 9.

Find the x-intercept of the line that passes through (-3,4) and is perpendicular to the graph of x-2y=7
Answer:
x - intercept = - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x - 2y = 7 ( subtract x from both sides )
- 2y = - x + 7 ( divide through by - 2 )
y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{7}{2}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2 , then
y = - 2x + c ← is the partial equation of the perpendicular line\to find c substitute (- 3, 4 ) into the partial equation
4 = 6 + c ⇒ c = 4 - 6 = - 2
y = - 2x - 2 ← equation of perpendicular line
to find the x- intercept let y = 0 into the equation and solve for x
- 2x - 2 = 0 ( add 2 to both sides )
- 2x = 2 ( divide both sides by - 2 )
x = - 1
the x- intercept of the perpendicular line is - 1 or (- 1, 0 )

The correct equation to solve for x is 2(2x-15)=2x-8 , and the value of x is 11 .
in the question ,
from the given figure , we can see that RL=LQ and PK=KQ which means
that L and K are the mid points of sides RQ and PQ respectively .
The Mid Point Theorem states that
If the line segment adjoining the mid points of any of the sides of the triangle then the line segment is said to be parallel to the third side and is half of the length of third side .
which means LK parallel to RP and RP/2=LK ( ... by mid point theorem)
Substituting the values of LK = 2x-15 and RP = 2x-8 .
(2x-8)/2=2x-15
Multiplying both sides by 2
2x-8 = 2(2x-15)
So, the equation to solve for x is 2(2x-15)=2x-8
Simplifying further
2x-8 = 4x-30
4x-2x= 30-8
2x = 22
x = 11
Therefore , the correct equation to solve for x is 2(2x-15)=2x-8 , and the value of x is 11 .
