Answer:
Almost 125 bats (124.92) can be lined up from home plate to the center field fence.
Step-by-step explanation:
We have a baseball field was measured to be 125 yards from Home Plate to deep center field.
We have to calculate how many baseball bats (91.5 cm in length) could be lined up (end to end) from home plate to the center field fence.
One yard is equivalent to 0.9144 meters.
One meter is equivalent to 100 cm.
Let D the distance from home plate to the center field fence and L the bat length.
Then, the amount of bats b that can be lined up is:
Answer:
n is 192
Step-by-step explanation:
Given data
Cl = 95%
interval = 0.2
to find out
what value n
solution
we have interval = 0.2
so interval has width at most is 0.5 so
margin of error E = 0.2 /2 = 0.1
and we know Z value for 95% Cl is 1.96 from z table
so sample n = Z²/E² ( ( 1 - 0.5) 0.5 + ( 1 - 0.5) 0.5 )
n = 1.96²/0.1² ( ( 1 - 0.5) 0.5 + ( 1 - 0.5) 0.5 )
n = 192.08
so n is 192
Answer:
1)
D. 3:2
2)
B. 40%
as, no. of girls=8
total no. of students =12+8=20
now,
percentage of girls=no.of girls/total no. of students ×100%
=8/20×100%
=40%
35.8 degree I think its c but not sure
good evening ,
______
Answer:
x=3 or x= -3
____________________
Step-by-step explanation:
x²=9 ⇔ x²-9=0 ⇔ (x-3)(x+3)=0 ⇔ x-3=0 or x+3=0 ⇔ x=3 or x= -3.
