Answer:
71 %
Step-by-step explanation:
Paper 1 :
65% of 120 = 0.65 X 120 = 78
Paper 2 :
80% of 80 = 0.8 X 80 = 64
Total Percentage:
Add the two scores 78 + 64 = 142
Add the what it was out of 120 + 80 = 200
Use (Score / Total marks available) X 100
(142 / 200) X 100 = 71
Simplify the expression by multiplying exponents
Simplify the expression by cancelling the terms
Answer:
Probability of no one picking up a defective product = 571 / 1540
Step-by-step explanation:
Total number of items = 22
non-defective items = 22-3 = 19
Probability of all three picking up non-defective products
= 19/22 * 18/21 * 17/20
= 969/1540
Probability of at least one picking up a defective product
= 1 - 969/1540
= 571/1540
(=0.371, approx.)
<u>8.60</u> = <u> X </u>
50 100
"Percent" means "out of one hundred" (Latin).
Multiply the top by two, since 100 is twice 50, and the fractions will be equal.
The answer is 17.2%.
Answer:
-z( 2z^3-5z^2+9z-1)
Step-by-step explanation:
Apply exponent rule: a^b+c=a^b*a^c
z^2=zz
z^3=z^2*z
z^4=z^3*z
Factor out common term z:
-z(2z^3-5z^2+9z-1)
