Answer:
Required probability is 0.9748
Step-by-step explanation:
given data
mean 
= 117.7-cm
standard deviation 
= 2.2-cm
sample size n = 29
solution
we consider here random variable which represents here length of rod= x
so get here first z that is express as
put here value with x value 118.5-cm
Z = 1.9582
p value is 0.9748
so required probability is 0.9748
Answer:
x=3
y=11
Step-by-step explanation:
y = 3x + 2 equation 1
y = 7x - 10 equation 2
using equation 1 in equation 2 we have:
3x + 2 = 7x - 10
2=7x - 3x -10
2 = 4x -10
2+10 = 4x
12= 4x
12/4 = x
we have:
x= 3
using equation 1:
y = 3x + 2
y= 3(3)+2
y=9+2
y=11
Answer:
2 quarters and 15 dimes
Step-by-step explanation:
2 quarters is equal to 50 cents, and because each dime is worth 10 cents, you need 10 cents x 15 dimes = 150 more cents to get to $2.
Hope this was helpful!
Have yourself an amazing day!
D - the shortest distance from the ship to the shore.
d / ( 17 - x ) = tan 32° = 0.62487
d / x = tan 53° = 1.32704
d = 0.62487 ( 17 - x )
d = 1.32704 x
0.62487 ( 17 - x ) = 1.32704 x
10.62279 - 0.62487 x = 1.32704 x
x = 10.62279 : 1.95191
x = 5.44226 miles
d = 5.44226 · 1.32704
Answer:
d = 7.222 miles
Change 48% to 0.48
0.48 x 18 = 8.64
rounded would be 9
