Mathematics

Andrew [12]3 years ago
3 0

Answer: 220

Step-by-step explanation:

When we wanto to create a group of K elements for a set of N elements (where the order of the K elements does not matter, so we do not considerate the permutations of the K elements), the number of possible combinations is:

C = \frac{N!}{(N - K)!*K!}

Here N = 12 and K = 3

C = \frac{12!}{9!*3!} = \frac{12*11*10}{3*2} = 220

So there are 220 possible combinations

What is a number sequence<br>​
disa [49]

Answer:

A number sequence is a list of numbers that are linked by a rule. If you work out the rule, you can work out the next numbers in the sequence. In this example, the difference between each number is 6. So the rule for this sequence is to add 6 each time. So now you can work it out the next number. 27 + 6 = 33.

The cost of a can ride , y, based on the number of miles driven , x, is represented by
lozanna [386]

Answer:

Step-by-step explanation:

y = 0.80x + 2.50

a 7 mile ride......x = 7

y = 0.80(7) + 2.50

y = 5.60 + 2.50

y = 8.10 <=== the 7 mile ride cost $ 8.10

the ride cost 13.70.....y = 13.70

13.70 = 0.80x + 2.50

13.70 - 2.50 = 0.80x

11.2 = 0.80x

11.2 / 0.80 = x

14 = x <=== u travel 14 miles

Researchers want to survey the mass of American alligators in a certain region. They want to maximize the efficiency of this eff
nikdorinn [45]

Answer:

Option B is correct.

An appropriate statistical test that can be used to evaluate the usefulness of this method is; Linear regression with t-test for significance of slope.

Step-by-step explanation:

For this research, they want to measure the lengths of alligators and use the already obtained data relating the lengths of captured and released alligators to their masses, to obtain the masses of alligators whose lengths have been measured.

So, in this research survey, the masses of the alligators is the dependent variable which depends on the lengths.

Basically, the researchers measure the length of an alligator and use the data to work out its mass.

So, an appropriate method to relate the two variables is to use regression analysis on the already obtained data, to obtain the linear relationship between mass of the alligators and their lengths. So that, just by putting on the measured lengths of the alligators surveyed into this expression, their corresponding masses would be immediately obtained.

But the correctness of this expression obtained will be checked by using t-test for the significance of the slope obtained in the linear regression.

So, the appropriate statistical test that can be used to evaluate the usefulness of this method is: Linear regression with t-test for significance of slope.

Hope this Helps!!!
