Answer:
Step-by-step explanation:
y - y1 = m(x - x1)
y - 5 = -9/2*(x - 4)
y -5 = -9/2x + 9*4/2
y - 5 = -9x/2 +9*2
y-5=-9x/2 + 18
y= -9x/2 + 18 +5
y= -9x/2 + 23 {y =mx+c}
Answer:

You can fit 153 flowers in a circle with the diameter of 14. You find the area of the circle by doing pi times 7 squared.
Answer:
C
Step-by-step explanation:
To factor x^2+8x+16, you have to find two numbers that add up to 8 and multiply to your constant, 16. 4 and 4 fit these requirements so you can factor them as (x+4)(x+4). Hope I explained it okay :)
<span>a.
</span>Do you
have sufficient funds to estimate the population mean for the attribute of
interest with a 95% confidence interval 4 units width? Assume that sd= 12
n= {[(Zalpha/2)^2]*[sd]^2}/
se^2
n=
(1.96)^2*(12)^2/ (2)^2
n=
138.297 rounded up to 139
<span>There
is not enough funds for this one
since you’ll need 139 pieces and it costs 10 a piece, you’ll need 1390.</span>
b.
90% confidence interval
n= {[(Zalpha/2)^2]*[sd]^2}/
se^2
n=
(1.645)^2*(12)^2/ (2)^2
n=98
There is enough
funds since 98 pieces for 10 a piece is equal to 980.
