Answer:
a) cos
b) sin
c) tan maybe?
Step-by-step explanation:
6/11
The square root of 36 is 6, and the square root of 121 is 11, giving you 6/11
<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.
Answer:
The answer is $26
Step-by-step explanation:
The pet store sold 2 kittens for $9 each which makes that 9+9 which equals 18
Now they sold 1 puppy for $8 so to get the total all together you will add 18+8 which equals 26. Thus they earned $26
