quadratic

cubic

exponential

Answer:

Answer:

Linear, exponential and quadratic.Step-by-step explanation:

Predictive modelling is used in statistics to predict certain outcomes from the analysis of a bunch of data, which was systematized.

The most common prediction model is linear regression, which is based on the calculation of a linear relation between variables that helps to predict future outcomes.

Also, exponential models are used to make predictions, but in this case it's used to predict exponential growth or decays like population growth of bacteria or people. This models, using current data, help to predict the population growth in the future.

In third place, quadratic modelling is applied in physics when we study projectiles, they describe a parabolic trajectory which is perfectly model with a quadratic function, which can use to predict important elements of the projectile like angle of launch, or how far is gonna get.

Therefore, the answer is linear, exponential and quadratic.

Answer: Linear, quadratic I think that's right

How to solve 3y=-8 please

What you want to do is isolate the y variable. So to do this you must get rid of the three that is being multiplied by y. The opposite of multiplication is division. Whatever you do on one side you do to the other so divide 3y by 3 and then divide -8 by 3. This cancels out the 3 and you should get y=-8/3 or y=-2 & 2/3 depending on if your teacher wants mixed fractions or not :)

3y=-8

Divide both sides by 3

Final Answer: y= -2.6667

Divide both sides by 3

Final Answer: y= -2.6667

A taxi charges $1.75 plus a fee of $0.75 for each mile traveled. The total cost of a ride, without a tip, is $4.75. How many miles is the trip? Use m for the number of miles traveled

.75m + 1.75 = 4.75

(.75m = 3.00)100

75m = 300

m = 4 miles

(.75m = 3.00)100

75m = 300

m = 4 miles

Answer:

4.75= 1.75+0.75x

x=4 miles

1)simplify both sides of equation

2) Flip te equation = 0.75x+1.75=4.75

3) Subtract 1.75 from both sides

4) Divide both sides by 0.75

Explain how to find the sum of two decimals

Well, when you add or subtract decimals, you must make sure that the decimal point is lined up, no matter how many decimals you have. Let's say you're adding 1.59 and 3.024. This is how you would set it up

2.59

+3.024

(Because I'm typing this, they don't match up perfectly, but you get the jist)

Next, you add normally, filling in zeros wherever there seems to be no number to add.

2.590

+3.024

=5.614

That's how you do it! Hope it helps!

A butcher is dividing a round of beef into 3 equal-sized roasts. If each roast weighs 7.9 pound, and there are 1.4 pounds of beef left over, how much did the round of beef weigh?

Each roast is 7.9 lbs so you multiply that by 3.

7.9x3=23.7

now add 1.4

23.7+1.4=25.1

the round of beef weighed 25.1 pounds

7.9x3=23.7

now add 1.4

23.7+1.4=25.1

the round of beef weighed 25.1 pounds

Determine which statement is a true proportion. Question 7 options: 10/9=11/10 1/2=3/4 12/42=10/35 48/56=40/48

Answer:

True proportion: 12/42 = 10/35.

Step-by-step explanation:

You can do this by performing the division. For example 10/9 = 1.11111.. and 11/10 = 1.1 so they are not proportional.

Or you can factor numerators and denominators and look for common factors.

For example 12/42 = 2 * 6 / 7 * 6 = 2/7

and 10 / 35 = 5*2 / 5*7 = 2/7.

So these 2 are proportional.

What is the point-slope form of the line with slope − 1/8

that passes through the point (−2, 1)? Multiple

choice

For this case we have that the point-slope form of a line is given by:

Where:

m: is the slope

are the coordinates of a point through which the line passes.

In this case we have to:

Substituting we have:

Simplifying:

Thus, the point-slope equation form of the line is:
