We know that
<span>20% --------------> were blue
</span><span>1/10---> 0.10----> 10%--------------> were white
</span><span>40% ---------------> were silver
</span>
and
<span>9 ---------> were gold
so
gold=100%-(20%+10%+40%)-------> 100%-70%------> 30%
30% ---------------------> is equal to 9
10% (</span>were white)<span>-------> X
X=10%*9/30%------> x=3
the answer is
3</span>
Answer:
we say for μ = 50.00 mm we be 95% confident that machine calibrated properly with ( 49.926757 , 50.033243 )
Step-by-step explanation:
Given data
n=29
mean of x = 49.98 mm
S = 0.14 mm
μ = 50.00 mm
Cl = 95%
to find out
Can we be 95% confident that machine calibrated properly
solution
we know from t table
t at 95% and n -1 = 29-1 = 28 is 2.048
so now
Now for 95% CI for mean is
(x - 2.048 × S/√n , x + 2.048 × S/√n )
(49.98 - 2.048 × 0.14/√29 , 49.98 + 2.048 × 0.14/√29 )
( 49.926757 , 50.033243 )
hence we say for μ = 50.00 mm we be 95% confident that machine calibrated properly with ( 49.926757 , 50.033243 )
Answer:
A handyman need 34 rows of 18 tiles.
How many total tiles does he need?
lets start off by saying that each row has 18 tiles
and there are supposed to be 34 rows
so you can multiply the number of tiles in each row (18) by the number of rows (34)
34 x 18 = 612
the handyman needs a total of 612 tiles to cover the floor.
