The probability that she won't buy either car is .10. You add the two probabilities that were previously stated and then subtract them from 1.00.
.52 + .38 = .90
1.00 - .90 = .10
Hey there! :)
When teachers ask you for the standard form in math, they are asking you to find the simplest form an equation with variables can be in.
Ax + By = C
Example : put y=2x -3 into standard form.
Subtract 2x from both sides.
-2x + y = -3 —> standard form.
Hope this helped! :)
Answer 5r^

−17r+5
Step-by-step explanation:
Changes made to your input should not affect the solution:
(1): "r2" was replaced by "r^2". 1 more similar replacement(s).

:
Equation at the end of step 1
(((8•(r2))-12r)+4)-((3r2+5r)-1)
STEP

:
((23r2 - 12r) + 4) - (3r2 + 5r - 1)
STEP

:
Trying to factor by splitting the middle term
3.1 Factoring 5r2-17r+5
The first term is, 5r2 its coefficient is 5 .
The middle term is, -17r its coefficient is -17 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 5 • 5 = 25
Step-2 : Find two factors of 25 whose sum equals the coefficient of the middle term, which is -17 .
-25 + -1 = -26
-5 + -5 = -10
-1 + -25 = -26
1 + 25 = 26
5 + 5 = 10
25 + 1 = 26
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
5r^2 - 17r + 5
The inequality is 4 ≥ x/2.1, and the answer is 8.4 ≥ x (or x ≤ 8.4).
To solve this, we multiply both sides by 2.1:
4*2.1 ≥ x
8.4 ≥ x.
Answer:
Converting kilometers to meters could never be simpler with our accurate length converter! ... Meters and kilometers both belong to the metric length scale, with these two units of measurement being on the larger side. ... 1 Kilometer equals 1000 Meters (1km = 1000m) ... 3 Kilometers equal 3000 Meters (3km = 3000m) ...
