Compute the permutation.

Mathematics

So you have 8 digits (number available) to form 3 digit numbers (number selected).

Using the formula ^{a} P_{c} where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.

The number of three digit numbers that can be formed = ^{8} P_{3}
                                                                                       = 336

                                                <span> O R

</span>By using the formula Permutation =  \frac{a ! }{( a - c) !} where a is the number of available digits and c is the number of digits to be selected.<span>

</span>⇒  Permutation = \frac{8 ! }{( 8 - 3) !}
<span>
</span>⇒  Permutation = \frac{40, 320 }{120}
<span>
</span>⇒ Permutation = 336<span>
</span>

What is (4c-d+0.2)^2-10c; c=3.1, d=4.6​
yuradex [85]

Good evening ,

______

Answer:

(4c-d+0.2)² - 10c = 33

___________________

Step-by-step explanation:

(4c-d+0.2)^2-10c

c=3.1, d=4.6​

(4(3.1) - 4.6 + 0.2)² - 10(3.1) = (12.4 - 4.6 + 0.2)² - 31 = (7.8 + 0.2)² -31 = 8² - 31 = 64-31 =33.

If a given data point is (1,4) and the line of best fit is y = 1.5x + 3.25, what's the residual value?
Svetlanka [38]

Answer:

The residual value is -0.75

Step-by-step explanation:

we know that  

The residual value is the observed value minus the predicted value.

RESIDUAL VALUE=[OBSERVED VALUE-PREDICTED VALUE]

where

Predicted value.--> the predicted value given the current regression equation

Observed value. --> The observed value for the dependent variable.

in this problem

we have the point (1,4)

so

The observed value is 4

<em>Find the predicted value  for x=1 </em>

y =1.5(1)+3.25=4.75

predicted value is 4.75

so

RESIDUAL VALUE=(4-4.75)=-0.75

56of the 90pets in the pet show are cats 4/5of the cats are calico cats. What fraction of the pets are calico cats?
meriva
To get the answer, we can divide 56 by 5 to find one fifth of the cats. Then, we can multiply this number to get four fifths of the cats. Then, we put this number over 90 since there is 90 pets in the entire show. Then, this answer ends up being about half all of the pets are calicos.
