Answer:
shape AREA= 35cm^2
Step-by-step explanation:
you should know that this shape is a combination of triangle and trapezoid. therefore you have to find the area of each shape and add them.
A=h/2(b1 + b2) for trapezoid
A=2/2((4+4)+4)
A=1*12
A=12cm^2
A=bh/2. for TRIANGLE
A=1/2((4+4)*5.75)
A=1/2(46)
A=23cm^2
shape AREA= triangle AREA + trapezoid AREA
shape AREA=12cm^2 + 23cm^2
shape AREA= 35cm^2
Step-by-step explanation:
(7x^4-4y^8)^2
( 5/3 + 2 2/5 ) ÷ ( 1 3/4 ) =
( 5×5/3×5 + 2 2×3/5×3 ) ÷ ( 4/4 + 3/4 ) =
( 25/15 + 2 6/15 ) ÷ ( 7/4 ) =
(25/15 + 30/15 + 6/15 ) ÷ ( 7/4 ) =
( 25 + 30 + 6 / 15 ) ÷ ( 7/4 ) =
( 61/15 ) ÷ ( 7/4 ) =
61/15 <em>×</em><em> </em><em>4</em><em>/</em><em>7</em><em> </em> =
61 × 4 / 15 × 7 =
244 / 105
Y=3x-1 is it linear function?YES :)
Answer:
Step-by-step explanation:
Given that, we have 1851 bullets that we KNOW are NOT MATCHES of one another. One by one they examine two bullets at a time.
So, there are 1851 bullets but each time we choose 2.
We have, N choose K = N! / K! (N-k)!
Here, N = 1851 and K = 2
Therefore, 1851 choose 2 = 1851! / 2! (1851-2)!
= 1851! / 2! * 1849!
= 1712175 Possible Combinations
Out of these 653 are false positive.
The chance of getting false positive is = 658 / 1712175
= 0.000384
= 0.0384 %
Therefore, The correct option is
The chance of false positive is 0.0384% Because this probability is sufficiently small (< or = 1%) There is high confidence in the agency's forensic evidence.
