Given the function f(x) = 4ˣ

evaluate f (-2)

The formula of  g(u) in terms of u is g(u) = (-12u + 2) / 8 by equation  -12u + 3 = 8v + 1.

To find a formula for g(u) in terms of u, we need to solve the given equation for v and express it in terms of u.

Starting with the equation: -12u + 3 = 8v + 1

Rearranging the terms, we have:

8v = -12u + 3 - 1

8v = -12u + 2

Dividing both sides of the equation by 8:

v = (-12u + 2) / 8

Therefore, the formula for g(u) in terms of u is:

g(u) = (-12u + 2) / 8

Answer: $150

Step-by-step explanation:

Hi, the question says:

Calculate the simple interest produced by $4500 at 5% simple annual interest in 8 months.

To answer this question we have to apply the simple interest formula:  

I = p x r x t  

Where:  

I = interest  

P = Principal Amount  

r = Interest Rate (decimal form)  

t = years  

Since 1 year = 12 months;  

For 8 months:

8/12 = 2/3 years  

Replacing with the values given  

I = 4500 x (5/100) x 2/3

I = $150

What is standard deviation?

The standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.

What is margin of error?

The margin of Error is a statistical expression that is used to determine the percentage point by which the result arrived will differ from the value of the entire population, and it is calculated by dividing the standard deviation of the population by the sample size and lastly multiplying the resultant with the critical factor.

Given,

margin of error = 0.5

Standard deviation = 5.4

To find the total water specimens.

Margin of Error = Z * ơ / √n

For two-sided confidence interva

p' = 1-α/2

α = 1- 0.90

= 0.1

p' = 1-0.1/2

p' = 0.95

The critical z value for cumulative probability of 0.95 is 1.64.

Margin of error = 1.64(5.4/\(\sqrt{n}\))

0.5 = 1.64(5.4/\(\sqrt{n}\))

n = 304

Step-by-step explanation:

∠JDG and ∠EDF are opposite angles. The measures of arcs for opposite angles always add up to 180°. Since the arc for ∠JDG is 50°, the arc for ∠EDF has to be 130°, because 50 + 130 = 180.

Answer:

9 miles

Step-by-step explanation:

Given data

A ride costs $1.50

$0.25 for each additional mile

Let the number of miles be x

and the cost of x miles be y

Hence the expression for the total cost is

y= 1.5+ 0.25x

now when y= 3.75

3.75= 1.5+0.25x

3.75-1.5= 0.25x

2.25= 0.25x

x= 2.25/0.25

x= 9 miles

Hence he must not go beyond 9 miles

To solve that question let's draw a Venn's Diagram:

The left circle represents all students that owned a car, and the right circle represents all students that owned an iPod. The intersection of the two circles represents students that owned both. We know that the intersection has 20 students, then

We also know that there are a total of 40 students that owned cars, 20 of them are in the intersection, which means that they owned both, then, there are 20 students that only owned a car

Now we can repeat the same logic to the iPod, there are a total of 40 students that owned iPods, 20 of them are in the intersection, then only 20 students only owned an iPod,

Then, there are 20 students that only owned an iPod, and 20 students that only owned a car. Then there are 40 students that owned either a car or an iPod.

Therefore, the three left cosets of h in z are: 0 + h = {x ∈ z | x ≡ 0 (mod 3)}, 1 + h = {x ∈ z | x ≡ 1 (mod 3)} and 2 + h = {x ∈ z | x ≡ 2 (mod 3)}.

Here, z denotes the set of all integers, and h = {0, 63, 66, 69, ...} is a subset of z.

To find the left cosets of h in z, we need to choose an integer a from z and then form the set of all integers of the form a + h, where a + h = {a + x | x ∈ h}.

For example, if we choose a = 5, then the left coset of h containing 5 is:

5 + h = {5 + x | x ∈ h} = {5, 68, 71, 74, ...}

To find all the left cosets of h, we can choose different values of a and repeat the process. However, we notice that all the elements of h have a common divisor of 3, since h contains 0 and all the other elements differ from 0 by a multiple of 3. Therefore, we can partition z into three sets:

z0 = {3n | n ∈ z} is the set of all integers that are multiples of 3.

z1 = {3n + 1 | n ∈ z} is the set of all integers that have a remainder of 1 when divided by 3.

z2 = {3n + 2 | n ∈ z} is the set of all integers that have a remainder of 2 when divided by 3.

We claim that each left coset of h in z belongs to exactly one of these sets. To see why, suppose that a + h and b + h are two left cosets of h in z. Then, for any x ∈ h, we have:

(a + x) - (b + x) = a - b

Since a - b is a fixed integer, it follows that either all the elements of a + h and b + h differ by the same integer (in which case a + h = b + h), or there are no common elements between a + h and b + h.

Now, we can compute the left coset of h containing 0, which is:

0 + h = {x ∈ z | x ≡ 0 (mod 3)}

This is because adding an element of h to 0 does not change its residue modulo 3. Therefore, the left coset of h containing 0 belongs to z0.

Next, we can choose an integer from z1 and compute its left coset. For example, if we choose a = 1, then:

1 + h = {x ∈ z | x ≡ 1 (mod 3)}

This left coset belongs to z1.

The correlation tests of whether two variables measured at the same point in time are correlated is cross-sectional. The answer is option(A).

The correlation tests the degree to which an earlier measure on 1 variable is associated with a later measure of the other variable and examines how people change over time is cross-lag. The answer is option(C)

The dependent variable and the variable that you're most interested and predicting is the criterion variable. The answer is option(A)

When research records, what happens in terms of behavior of attitudes based on self-report, behavioral observations, or physiological measures is referred to as measured variable. The answer is option(C)

When the researcher assigns participants to a particular level of the variable this is referred to as manipulated variable. The answer is option(B)

Cross-sectional studies measure variables at a single point in time and examine their correlation. It does not involve the measurement of variables over time. Cross-lag correlation focuses on how variables change over time and the direction of their influence. Criterion variable is the variable that the researcher wants to predict or explain based on other variables. When research records what happens in terms of behavior, attitudes, or other phenomena using self-report measures, behavioral observations, or physiological measures, it is referred to as measuring variables. The manipulated variable allows the researcher to manipulate the independent variable and observe its effect on the dependent variable.

Therefore, further research would be needed to determine if the relationship between the price of gasoline and gasoline consumption holds at higher prices.

A linear correlation coefficient of 0.7 indicates a strong positive linear relationship between the price of gasoline and gasoline consumption. In other words, as the price of gasoline increases, gasoline consumption also tends to increase. However, correlation does not necessarily imply causation, and there may be other factors at play that influence gasoline consumption.

It is not necessarily reliable to apply the results of this study to prices of gasoline higher than $5.30 per gallon because the study only included gasoline prices within that range. Extrapolating the results beyond the range of data may lead to inaccurate predictions or conclusions. Additionally, there may be other factors at play at higher prices that were not present within the range of prices studied.

\(M = 3D\) ---- equation 2

A microscope costs S51 and a dissection kit costs S17

Step-by-step explanation:

Given

Represent microscope with M and Dissection kits with D

Cost:

\(M = 3D\)

\(Total = 2278\)

Required

Represent as an equation:

To do this, we represent the equation in terms of cost and quantity

In terms of cost, we have:

\(26M + 56D = 2278\) ---- equation 1

and

\(M = 3D\) ---- equation 2

Substitute 3D for M in equation 1

\(26*3D + 56D = 2278\)

\(78D + 56D = 2278\)

\(134D = 2278\)

Divide both sides by 134

\(D = \frac{2278}{134}\)

\(D = 17\)

Substitute 17 for D in \(M = 3D\)

\(M = 3 * 17\)

\(M = 51\)

Hence:

A microscope costs S51 and a dissection kit costs S17
