What inequality that can be used to represent the problem

Answer:

4/3

Step-by-step explanation:

to find slope just choose any two points on the line and subtract them. I prefer choosing points that lie on the grid for instance in #11

I will choose Point 1: (4,3) and Point 2: (1,-1) because the intersect the grid and I can do 'clean' subtractions.

Slope = rise/run

= change in y/change in x

= y2-y1/x2-x1

= ( -1 - 3 ) / ( 1 - 4 )

= - 4 / -3

= 4/3

This is Single-Blinded Randomized Controlled trial type of study because the recipient is unaware that they are receiving a treatment, only the researchers are aware of who is receiving which treatment. So the option d is correct.

One of the most rigorous research designs is experimental research, which is frequently referred to as the "gold standard" in research designs.

This design involves the researcher manipulating one or more independent variables (as treatments), randomly assigning individuals to various treatment levels (random assignment), and observing the effects of the treatments on outcomes (dependent variables).

Experimental research has a distinct advantage in that it may link cause and effect through treatment manipulation while controlling for the erroneous effect of unrelated variables, which is known as internal validity (causality).

In order to achieve a bigger splash in their next trial, all the students must need to do is use a ball with a larger circumference.

Displacement and volume are defined as a dimensional object dropped into a liquid that will always displace its own volume from the liquid.

For a basketball, the circumference is a function of its volume. In other words, the larger the circumference, the larger the volume.

This defines that a basketball with a larger volume will displace more water from the pool than one with a lower volume.

Finally, to make a bigger splash, a basketball with a larger circumference would be needed.

The plot of absorbance vs. concentration shows 8 data points with 3 lines drawn to represent the data. In order to determine the best-fit line, we need to evaluate the lines based on how well they represent the data points.

(a) The red line is the middle line and goes through 1 data point, with 3 data points above it and 4 data points below it. This line has a slope that is between the slopes of the other two lines. However, it doesn't go through many of the data points and the slope is not consistent with the majority of the data points.

(b) The green line is the top line and touches 3 of the data points, with the rest of the data points below it. This line has a steeper slope compared to the red line, but it doesn't touch many of the data points and has a significant deviation from the majority of the data points.

(c) The blue line is the bottom line and has 2 data points below it and 6 data points above it. This line has a slope that is more consistent with the majority of the data points, and it has the least deviation from the data points compared to the other two lines.

The distance between the top of the ladder and the ground is decreasing at a rate of 10 meters per minute.

Let's call the distance between the bottom of the ladder and the wall as "x".

At a certain instant, x = 3636 meters

The rate of change of x with respect to time is 10 meters per minute, so dx/dt = 10 m/min.

At that same instant, the height of the ladder above the ground can be expressed as

h = (3939 - x)

since the ladder is 3939 meters long

The rate of change of h with respect to time can be found using the chain rule of differentiation.

dh/dt = dh/dx * dx/dt = -10 m/min

So, at the instant when the bottom of the ladder is 3636 meters from the wall, the rate of change of the distance between the top of the ladder and the ground is -10 meters per minute. This means that the distance between the top of the ladder and the ground is decreasing at a rate of 10 meters per minute.

Answer: The hypotenuse are both 13 cm

Step-by-step explanation:

The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

So, in this case:

c^2 = a^2 + b^2

c^2 = 5^2 + 12^2

c^2 = 25 + 144

c^2 = 169

c = √169

c = 13

So the length of the hypotenuse is 13 cm.

Next, we can use the Pythagorean theorem to find the length of the segments into which the bisector of the right angle divides the hypotenuse. Let's call the length of the segments x. Then, the segments form two right triangles with legs of length x and (13-x)/2.

Using the Pythagorean theorem on each triangle, we have:

x^2 + ((13-x)/2)^2 = 13^2

x^2 + (13-x)^2/4 = 169

x^2 + (13^2 - 2x(13) + x^2)/4 = 169

x^2 + (13^2 - 2x(13))/4 = 169

x^2 + (169 - 26x)/4 = 169

x^2 + 169 - 26x = 676

x^2 - 26x + 507 = 0

Now, we can use the quadratic formula to find x:

x = (-b ± √(b^2 - 4ac)) / 2a

a = 1, b = -26, c = 507

x = (26 ± √(26^2 - 4 * 1 * 507)) / 2 * 1

x = (26 ± √(676)) / 2

x = (26 ± 26) / 2

x = 26 / 2

x = 13

So, the lengths of the segments into which the bisector of the right angle divides the hypotenuse are both 13 cm, to the nearest tenth.

The simplified form of the expression (42x + 62y) + (38x - 4y) is 80x + 58y.

Given the expression in the question

(42x + 62y) + (38x - 4y)

To simplify, collect and add like terms.

(42x + 62y) + (38x - 4y)

42x + 62y + 38x - 4y

Collect like term

42x + 38x - 4y + 62y

Add 42x and 38x

The type of transaction described in the problem is called an installment purchase.

What is the simple interest?

Simple interest is a type of interest that is calculated on the principal amount of a loan or investment for a specific period of time.

The type of transaction described in the problem is called an installment purchase. In this type of transaction, a buyer pays a deposit at the time of purchase and then makes periodic payments, typically over a fixed period of time, until the full purchase price is paid off. In this case, the buyer pays a deposit of R999 and then pays off the remaining balance over a period of 3 years using simple interest.

To calculate the total amount that the buyer will pay over the 3-year period, we need to calculate the amount of interest that will be charged on the remaining balance. Since simple interest is being used, we can use the formula I = Prt, where I is the interest, P is the principal (the remaining balance), r is the interest rate, and t is the time period.

Assuming an annual interest rate of, for example, 5%, the interest charged on the remaining balance of R4000 (the original price minus the deposit) over 3 years would be:

I = Prt

I = 4000 * 0.05 * 3

I = R600

So the total amount that the buyer will pay over the 3-year period is:

R999 (deposit) + R4000 (remaining balance) + R600 (interest) = R5599

the total cost of the binoculars over the 3-year period will be R5599.

Hence, The type of transaction described in the problem is called an installment purchase.

It would be appropriate to construct a t-interval to estimate the population mean.

To determine whether it is appropriate to construct a t interval to estimate the population means, we need to consider if the sample size is large enough and if the population standard deviation is known.

If the sample size is less than 30 and the population standard deviation is not known, then it would be appropriate to use a t-interval.In this case, the sample size is 32, which is large enough to assume that the sample mean is an accurate representation of the population mean.

However, the population standard deviation is not known, so it would be appropriate to use a t interval. The t interval can be calculated using the sample mean, sample standard deviation, and degrees of freedom, which is the sample size minus 1.
