Here's what I got for the first question.
Did you want answers for the second one? I couldn't read that part of the image very well, if you did.
Answer:
11 weeks
Step-by-step explanation:
34+10x=144 equation
10x=110
x=11
check answer
11*$10=$110 money after 11 weeks at $10/week
+. 34 money saved
=. 144 money needed.
N = number of seeds planted
P = probability of germination
K = number that germinated
Using probability calculation:
p(x = k) = (n k) x 0.90^K x 0.10^n-k
p(10) = (12 10) x 0.90^10 x 0.10^2
P(10) = 0.2310
Lets smaller number is x
<span>The greater number is 8 more than the smaller number : x + 8
</span><span>The sum of two numbers is 72: x +( x + 8)= 72
answer
</span><span>x + (x + 8) = 72</span>
