Answer:
a) 103, b) No
Step-by-step explanation:
a) We need to multiply the probability by the amount of the sample to get:
200 × 51.6% = 103.2, rounded down to 103
b) As we have selected the people randomly, we have no control over the type of people we are given - this is theoretical and the estimate is not definite - all of the sample could have murdered by firearm or even none (even though it is highly unlikely).
Answer:
32
Step-by-step explanation:
Answer:
He has a total of 32 cones
Step-by-step explanation:
group the 1st 2 terms and last 2 terms:
(Z63 -2z^2) + (9z-18)
factor out GCF:
z^2(z-2) + 9(z-2)
now factor the polynomial:
(z-2) (z^2+9)
Y = -x²
y = -7x²
<u>y = 2/3x²</u>
<u>3y</u> = <u>-7 1/3x²
</u> 3 3
y = -2 4/9x
