Answer:
3x7 • (4x2 - 5x + 3)
Step-by-step explanation:
End of step 1- (3 • (x7)) • ((22x2 - 5x) + 3)
End step 2- 3x7 • (4x2 - 5x + 3)
Step 3-Trying to factor by splitting the middle term
3.1 Factoring 4x2-5x+3
The first term is, 4x2 its coefficient is 4 .
The middle term is, -5x its coefficient is -5 .
The last term, "the constant", is +3
Step-1 : Multiply the coefficient of the first term by the constant 4 • 3 = 12
Step-2 : Find two factors of 12 whose sum equals the coefficient of the middle term, which is -5 .
-12 + -1 = -13
-6 + -2 = -8
-4 + -3 = -7
-3 + -4 = -7
-2 + -6 = -8
-1 + -12 = -13
1 + 12 = 13
2 + 6 = 8
3 + 4 = 7
4 + 3 = 7
6 + 2 = 8
12 + 1 = 13
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
3x7 • (4x2 - 5x + 3)
Answer:
<u>The correct answer is z = 1.2</u>
Step-by-step explanation:
μ or average income = US$ 3,000
σ or standard deviation = US$ 250
Income in a given month = US$ 3,300
For calculating the z score, we use the following formula:
z = (x – μ) / σ
z = (3,300 – 3,000 / 250)
z = 300/250
z = 6/5 = 1.2
Interpreting z
A Z score tells us how many units of standard deviation (1.2 in this case)from the average a given score is, that is, we do not count in quantity of points, but in quantities of standard deviations. To use the Z score we require the distribution to be normal and to know the average and standard deviation of the scores.
Answer:
25. rational
26. irrational
Step-by-step explanation:
A rational number is a number that can be written as a fraction. It may have decimals that end or repeating decimals.
An irrational number cannot be written as a fraction. It's decimals continue on and do not repeat.
25.
When you multiply two rational numbers, the product is rational. The square root of 16 is 4, which is rational because it is a whole number. 4/7 is written as a fraction so it is rational.
26.
The square root of 2 is an irrational number because its decimals go on and do not repeat. 7 is a whole number so it is rational. Subtracting a irrational number from a rational number gives an irrational number.
