Student is asked
to evaluate the expression 2 to the power of 4/ 2 to the power of 7 =8
What error did the student make? Explain. Then
evaluate the expression.
The value of the expression 2⁴/2⁷ = 1/8.
A student is asked to evaluate the expression 2⁴/2⁷.
And the student wrote the answer for this expression as 8.
The student made the mistake of subtracting 7 from 4.
4 - 7 = -3, but the student might have done 7 - 4 = 3 and arrived at the answer as 2³ = 8.
Let us evaluate the given expression.
2⁴/2⁷
Apply exponent rule aⁿ/aˣ = aⁿ⁻ˣ
2⁴/2⁷ = 2⁴ ⁻ ⁷
⇒ 2⁴/2⁷ = 2⁻³ (subtract the numbers: 4 - 7 = -3)
⇒ 2⁴/2⁷ = 1/2³ (apply the exponent rule: a⁻ⁿ = 1/aⁿ)
⇒ 2⁴/2⁷ = 1/8 (2³ = 2 × 2 × 2 = 8)
⇒ 2⁴/2⁷ = 1/8

Answer:
x = 35
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
x + 52 + x + 2x - 12 = 180
4x + 40 = 180 ( subtract 40 from both sides )
4x = 140 ( divide both sides by 4 )
x = 35
Evaluate -2x(to the second power) for x= -3
The value of the expression when x = -3 is - 18

From the information given, we have;
-2x(to the second power)
This is expressed as;
-2x²
Now, let's substitute the value of x as -3, we get;

on an average, the number of students that choose to study arts subjects at greyin tide university is 17 each year. (hint: use poisson distribution formula. what is the probability that exactly 13 students will take up arts in the coming year?
The likelihood that exactly 13 students will pursue arts in the coming year is 76.47%.
What do we mean by probability?Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how probable they are. Statistics is the study of events governed by probability.So, to find the probability:
Given:
Each year, there are 17 students who study art.We now want to calculate the likelihood that 13 students will pursue arts in the following year.
That is,
P(13 will take art the next year) = 13/17 × 100%P(13 will take art the next year) = 76.47%Therefore, the likelihood that exactly 13 students will pursue arts in the coming year is 76.47%.

You want an average of at least 30 active minutes each day during the week. How many active minutes do you need on Sunday to achieve your goal? Make an argument for your answer using a bar graph.
Using the mean concept, it is found that you need at least 40 active minutes on Sunday to achieve your goal.
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
In a week, there will be 7 observations, and a bar graph can represent each observation(time in minutes). They are given as follows:
15, 45, 20, 0, 60, 30 and x.
We want the mean to be of 30, hence:
30 = (15 + 45 + 20 + 0 + 60 + 30 + x)/7
170 + x = 210
x = 210 - 170
x = 40.

The standard deviation of the method is 0.7193.
Standard Deviation:
Standard deviation of a data set is the square root of the calculated variance of a set of data.
The formula for standard deviation is,
[tex]\sigma^2 = \dfrac{\Sigma (x_{i} - \mu)^2}{n}[/tex]
Where
xi is an individual value
μ is the mean/expected value
N is the total number of values
Given,
Data set:
20.0, 20.0, 20.0, 20.1, 20.2, 20.5, 20.5, 20.6, 20.7, 20.7, 21.0, 21.2, 21.5, 21.6, 22.1, 22.3
Here we need to find the standard deviation.
To find the standard deviation we have to identify the following from the given set,
They are,
Count, N: 16
Sum, Σx: 333
Mean, μ: 20.8125
Now we have to apply the values on the formula,
In order to solve it,
[tex]\sigma^2=\frac{[(20-20.8125)^2+....+(22.3-20.8125)^2]}{16}[/tex]
When we simplify it then we get,
[tex]\sigma^2=\frac{8.2775}{16}[/tex]
So,
σ = √0.51734375
σ = 0.7193
