The simplified form of the expression √x × ⁴√x in rational exponent form is x^3/4.

Given that, square root of x times the fourth root of x.

√x × ⁴√x

To simplify the expression, rewrite using the least common index of 4.

Since ⁿ√xᵃ = x^(x/n)

√x = x^(1/2)

and

⁴√x = x^(1/4)

Hence, we have;

x^(1/2) ×  x^(1/4)

Using exponent rule

x^( 1/2 + 2/4 )

Add 1/2 and 1/4

x^( 1/2 + 1/4 )

x^3/4

Answer:

Reasonable

Step-by-step explanation:

The comparison 3.84 > 3.8 is reasonable.

In this comparison, 3.84 is a larger number than 3.8, so it makes sense to say that 3.84 is greater than 3.8. When comparing decimal numbers, we can simply compare the values to the right of the decimal point. In this case, both 3.84 and 3.8 have two digits to the right of the decimal point, so we can compare those digits directly. Since 4 is greater than 8, it follows that 3.84 is greater than 3.8.

The comparison is reasonable because it is based on a correct understanding of the relative sizes of the numbers involved.

Answer:

Step-by-step explanation:

The slope of a line between two points (x1, y1) and (x2, y2) is given by:

m = (y2 - y1) / (x2 - x1)

In this case, we are given that m = -1/2, so substituting in the two points we have:

-1/2 = (9 - 12) / (x - 8)

Expanding and simplifying the equation:

-1/2 = -3 / (x - 8)

Multiplying both sides by -2:

1 = 3 / (x - 8)

Multiplying both sides by (x - 8):

x - 8 = 3

Adding 8 to both sides:

x = 11

So the x-coordinate of the second point is x = 11.

Paul records data that the number of hot chocolates sold increases as temperature outside decreases. The depiction of the finding is "There is a correlation between two variables". So, the correct option is A.

Specifically, the data suggest that there is a relationship between two variables - the number of hot chocolates sold and the temperature outside.

When the temperature outside decreases, more hot chocolates are sold, and when the temperature increases, fewer hot chocolates are sold. This indicates that there is a correlation between the two variables, as they appear to be related.

However, we cannot determine from this information alone whether the correlation is strong or weak, or whether it is positive or negative.

The strength of the correlation would depend on how much the sales of hot chocolate increase or decrease as the temperature changes, while the direction of the correlation (positive or negative) would depend on whether the increase or decrease in hot chocolate sales is associated with an increase or decrease in temperature, respectively.

Answer:

y = 2 and x = 6

Step-by-step explanation:

Let y = x - 4 be  equation a

Let 4x + y = 26 be equation b

Substitute a into b:

4x + (x-4) = 26

5x - 4 = 26

5x = 30

x = 6

Substitute the value of x into a:

y = x - 4

y = 6 - 4

y = 2

CHECK:

4x + y = 26

4*6 + 2 = 26

24 + 2 = 26

26 = 26

LHS = RHS

Therefore, y = 2 and x = 6

The speed at which Ken should run to overtake Joe by 7.30 is 9mi/h.

What is meant by the speed of an object?

The size of a change in an object's position over time is measured by its speed. The rate at which an object travels a distance can be thought of as its speed. A fast-moving object travels at a high speed and completes a significant distance in a brief period of time. This is in contrast to an object travelling slowly, which travels a relatively short distance in the same length of time. It is a scalar value.

Given,

Time at which Joe starts jogging  = 7 am

Time at which Ken starts jogging = 7.10 am

Speed of Joe = 6mi/h

Let Speed of Ken required to overtake Joe = x mi/h

Since Ken has to overtake Joe by 7.30, both will have travelled the same distance by 7.30.

Time taken by Ken to cover the distance = 7.30 - 7.10  20 minutes = 20/60=1/3 h

Time taken by Joe to cover the distance = 7.30 - 7 = 30 minutes = 1/2 h

Distance = speed * time

Both cover the same distance.

6 * 1/2 = x * 1/3

x = 9 mi/h

Therefore the speed at which Ken should run to overtake Joe by 7.30 is 9mi/h.

The snail moves a distance of 40 yards in one hour as it moves at a speed of 2 feet per minute.

We can start by converting the speed of the snail from feet per minute to yards per hour, since the distance moved is given in yards per hour.

There are 60 minutes in an hour, so the snail's speed in yards per hour is:

2 feet per minute * 60 minutes per hour * (1/3) yards per foot = 40 yards per hour

Hence,

The snail moves a distance of 40 yards in one hour.

Since we are given that the snail has moved a total of 3 yards, we can find the amount of time it took by dividing the distance by the rate:

time = distance / rate

time = 3 yards / 40 yards per hour

time = 0.075 hours or 4.5 minutes

Therefore, the snail will move a distance of 3 yards after 4.5 minutes and distance of 40 yards in one hour.

For the given width length ratio and perimeter of rectangle, the length of rectangle is 80 cm.

The perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape.

Let the width of the rectangle be 3x, and the length be 4x (since the ratio of the width to the length is 3:4).

The perimeter of a rectangle is the sum of the lengths of all four sides, so we have:

Perimeter = 2(length + width)

Substituting the expressions for the length and width, we get:

280cm = 2(4x + 3x)

Simplifying the right-hand side, we get:

280cm = 14x

Dividing both sides by 14, we get:

x = 20

Therefore, the length of the rectangle is 4x = 4(20) = 80 cm

It says the initial value is $200000 so you can eliminate B and D because they start at $100000. That leaves A and C. C is increasing at a higher rate and is greater than 100% per year. That leaves option A.

The correct relationship of the three principles is: The well-ordering principle for the integers is equivalent to strong mathematical induction, and neither is equivalent to weak mathematical induction.

The well-ordering principle for the integers states that every non-empty set of non-negative integers has a least element. Strong mathematical induction is a proof technique that involves proving that a statement is true for a base case, and then assuming that it is true for all cases up to a certain value, and then proving that it must also be true for the next case.

This requires assuming the truth of all cases up to a certain value, which is where the well-ordering principle comes in. Weak mathematical induction is a proof technique that involves proving that a statement is true for a base case, and then assuming that it is true for a particular case, and then proving that it must also be true for the next case.

Weak mathematical induction does not require assuming the truth of all cases up to a certain value, and is therefore weaker than strong mathematical induction.

The answer is (b) The margin of error will be about 2 times larger.

The margin of error in a confidence interval is affected by the sample size, so decreasing the sample size will generally increase the margin of error. Specifically, the margin of error is inversely proportional to the square root of the sample size.

That is, if we reduce the sample size by a factor of k, then the margin of error will increase by a factor of sqrt(k).

In this case, the original sample size was 1000, and the proposed sample size is 250, which is 1/4 of the original size. Therefore, the margin of error for the smaller sample will be:

sqrt(1000/250) times the original margin of error.

Simplifying this expression, we get:

sqrt(4) times the original margin of error.

So the margin of error for the smaller sample will be about 2 times the original margin of error.

Step-by-step explanation:

A test score that is 1.4 standard deviations above the mean is 107. This means that a student who scored 107 on this standardized test would be above average, as the mean is 100 and the standard deviation is 5.

To find the test score that is 1.4 standard deviations above the mean, we need to use the formula:

z = (x - μ) / σ

where z is the number of standard deviations from the mean, x is the test score, μ is the mean, and σ is the standard deviation.

In this case, we know that z = 1.4, μ = 100, and σ = 5. So we can rearrange the formula to solve for x:

x = z * σ + μ

Substituting the values we know, we get:

x = 1.4 * 5 + 100 = 107

Therefore, a test score that is 1.4 standard deviations above the mean is 107. This means that a student who scored 107 on this standardized test would be above average, as the mean is 100 and the standard deviation is 5.

The choice between using the standard deviation and standard error in the denominator of a z-score formula depends on the context of the problem and the type of data being analyzed.

To determine which z-score formula to use, consider the type of data and the context of the problem. If you have a sample with a known population standard deviation, use the first formula.  If the data represents a random sample of a larger population, the standard error is typically used to account for the variability in estimating the population mean. On the other hand, if the data represents the entire population, the standard deviation is used as the denominator. It's important to understand the distinction between a sample and a population and to choose the appropriate formula accordingly.

4x - 3y + q = 0                [2]

If x = 1 and y = 2, then substituting for these values in each equation will provide a solution for p and q

Plugging x = 1 in Equation [1]:
3(1) - p(2) = 4

-2p = 1

-2p/-2 = 1/-2

p = -1/2
