The correct option D. f(x) = 5(5)ˣ and E. f(x) = 5(1/5)⁻ˣ, for the reflected function over the y-axis.
Explain the term reflected over the y-axis?The y-coordinate stays the same when a point is reflected across the y-axis, but the x-coordinate is assumed to be an additive inverse.We are aware of:
f(x) = 5(1/5)ˣ
Positive x-values and negative x-values are switched by a reflection over the y-axis, which also swaps the values of x and x.
Therefore:
f(ax) = f(x)
The following will be the value of the supplied function's y-axis reflection:
(Remember to swap out positive and negative x-values.)
f(x) = 5(1/5)⁻ˣ
A comparable form will be:
f(x) = 5(1/5)⁻ˣ
f(x) = 5(1/5)⁽⁻¹⁾⁽ˣ⁾
f(x) = 5[(1/5)⁻¹]ˣ
f(x) = 5(5)ˣ
Therefore

a poll was conducted two weeks before an election and showed that the incumbent would win with 54% of the vote, with a 3% margin of error. what is the confidence interval for this poll?
The confidence interval for the given poll is; 51% to 57%
How to find the confidence Interval?We are given that;
Sample proportion; p = 54% = 0.54
Margin of error; E = 3% = 0.03
Now, formula for confidence interval of proportions is;
p ± E
where;
p is sample proportion
E is margin of error
Thus;
CI = 0.54 ± 0.03
CI = (0.54 - 0.03), (0.54 + 0.03)
CI = (0.51, 0.57)
We conclude that the confidence interval is CI = (0.51, 0.57)

the impact on the error probability of part is on Decreasing trends of the test procedure
A Type II error is when we fail to reject a false null hypothesis. Higher values of α make it easier to reject the null hypothesis, so choosing higher values for α can reduce the probability of a Type II error.
The consequence here is that if the null hypothesis is true, increasing α makes it more likely that we commit a Type I error (rejecting a true null hypothesis).
So using lower values of α can increase the probability of a Type II error.

Michael’s class grew plants as part of the experiment. Michael’s plant grew 1/12 inch in the first week, 3/12 of an inch in the second week, and 5/12 of an inch in the third week. How much did Michael’s plant grow in those three weeks?
Answer:
{ No SIMPLIFIED: [tex]\frac{9}{12} inches[/tex] }
{ SIMPLIFIED: [tex]\frac{3}{4} inches[/tex] }
Step-by-step explanation:
If we want to know about the plant grows, we need to add the fractions in 3 weeks with this solution:
[ The inch of the plant 1st week ] + [ The inch of the plant 2nd week ] + [ The inch of the plant 3rd week ] = [ The inch of the plant in 3 weeks ]
Look at the denominator of 3 weeks, it is 12 and the numerators are 1,3,5
To plus the fraction we remain the denominator and plus the numerators together which we can result in this equation:
[tex]\frac{1}{12}[/tex] + [tex]\frac{3}{12}[/tex] + [tex]\frac{5}{12}[/tex] = [tex]\frac{1 + 3 + 5}{12}[/tex] = [tex]\frac{9}{12}[/tex] { SIMPLIFIED: [tex]\frac{9 : 3 }{12 : 3} = \frac{3}{4}[/tex] }
So then we see that if you choose no simplified then: Michael's plant grow [tex]\frac{9}{12}[/tex] inches in 3 weeks or you could choose the simpliflied one then: Michael's plant grow [tex]\frac{3}{4}[/tex] inches in 3 weeks.

y = -1/2x + 10
y = -2x + 10
The function that models the data in the given table is: D. y = -2x + 10.
How to Write the Function that Models the Data in a Table?The function that models the data of a table can be expressed in the slope-intercept form as y = mx + b, where:
the slope = m = change in y / change in x.y-intercept = b.Find the slope of the function using two pairs of values from the table, (6, -2) and (10, -10):

What is meant by direct proportion ?The relationship between two values where their ratio equals a constant number is known as a direct proportion or direct variation. It is symbolised by the proportional sign ().
According to the direct proportion formula, if y is directly proportional to x, we can state that y = kx, where k is a constant. Y = kx also serves as the direct proportion equation's general form.
When one quantity increases or declines, the other quantity also rises or falls in direct proportion. On the other hand, in indirect or inverse proportion, if one quantity rises, the other one falls, and vice versa.
m= 8p

The force of moving blood exerted on the walls of blood arteries is known as blood pressure. The heart's action of pumping blood through the circulatory system is mostly responsible for this pressure. The pressure in the major arteries is meant when the word "blood pressure" is used without qualifier.
As the data is normally distributed we can use standard normal z table to estimate the answers.
Z = (x-mean)/s.d
Given mean = 121.
S.d = 15.
P(X<142).
Z = (142-121)/15 = 1.4
From z table,
P(z<1.8) = 0.9641 ~ 96.41%
P(X>130).
Z = (130-121)/15 = 0.6
From z table,
P(z>0.6) = 0.8849
P(112<X<130) = P(X<130)-P(X<112).

rate: $--------, regular hours: N/A, overtime: ---------, total: $----------
gross: $----------
Fred's pay for the specified week, with a rate of $11.25 for regular hours and time and a half for overtime, and number of hours worked of 48.5 hours is presented by completing the attached table as follows;
Rate: $11.25, regular hours: 40, overtime: N/A, total: $450
Rate: $16.875, regular hours: N/A, overtime: 8.5, total: $143.4375
Gross: $593.4375
What is a payment rate?A payment rate is the amount of payment or money that is received in a unit of time.
The amount Fred earns per hour = $11.25
The number of regular hours Fred works per week = 40
The rate at which he is paid for overtime = Time and a half
The number of hours Fred works in the specified week = 48.5 hours
Therefore, the amount Fred earns for working overtime = 1.5 × $11.25 = $16.875
The amount Fred earns for regular hours during the specified week = 40 × $11.25 = $450
The number of overtime hours Fred works for during the week = 48.5 - 40 = 8.5
The amount Fred earns for the overtime work = 8.5 × $16.875 = $143.4375
Fred's gross payment for the week is therefore; $450 + $143.4375 = $593.4375
The table can therefore be completed by plugging in the above values as follows;
Rate: $11.25, regular hours: 40, overtime: N/A, total: $450
Rate: $16.875, regular hours: N/A, overtime: 8.5, total: $143.4375

In the given question, we have to find the gradient vector field of f and sketch it.
f(x,y)= √(x^2+y^2)
To find the gradient, it's just the partial derivatives for x and y
∇(f) = ∂f/∂x i + ∂f/∂y j
In this case, we have
∂f/∂x = x/√(x^2+y^2) and ∂f/∂y = y/√(x^2+y^2). So
∇(f) = x/√(x^2+y^2) i + x/√(x^2+y^2) j
We can write it as
∇(f) = (xi+yj)/√(x^2+y^2).
This is a unitary vector field everywhere, with the exception of the origin, where it is undefined, where we can see it as the vector xi+yj divided by the magnitude √(x^2+y^2). From the starting point, the direction is outward.
