1st you have to find what x, and y is
2nd re write the problem
3rd solve it
Answer:
a) 0.108
b) 1.00
c) 0.170
d) 0.0109
e) 0.0121
f) 0.999
Step-by-step explanation:
Success: p = 0.15
Failure: q = 1 - p = 0.85
a) q²p = 0.85² × 0.15
= 0.108375 = 0.108 (3 sf)
b) 1 - P(all hits)
= 1 - p⁷ = 1 - 0.15⁷
= 0.9999982914= 1.00 (3 sf)
c) q³p + q⁴p = 0.1704196875
= 0.170 (3 sf)
d) 7C4×p⁴×q³ = 35 × 0.15⁴ × 0.85³
= 0.01088152734 = 0.0109 (3 sf)
e) P(4,5,6 or 7)
= 7C4×p⁴×q³ + 7C5×p⁵×q² +
7C6×p⁶×q + 7C7×p⁷×q⁰
= 0.01210317188 = 0.0121 (3 sf)
f) 1 - P(more than 4)
= 1-(0.01210317188-0.01088152734)
= 1 - 0.001221644531
= 0.9987783555 = 0.999 (3 sf)
Answer:
1/2
Step-by-step explanation:
So we multiply 2 by 6, and get 12.
Then we multiply 1 by 3, and get 3.
Next we give both terms new denominators
So now our fractions look like this:
12/18-3/18
Since our denominators match, we can subtract the numerators.
12 − 3 = 9
So the answer is:
9/18
So we reduce it:
9/18divided by 3=3/6
so since it’s equivalent we reduce it again
3/6divided by 3 which equals 1/2
and that’s our final answer 1/2
I hoped that this helps :)
