The distance from florist to movie theater is about 3.5 km on the same street.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
A book store and a movie theater are 6 kilometers apart. The florist is on the same street, 2.5 kilometers from the theater. Hence:
Distance from book store to movie theater = Distance from book store to florist + Distance from florist to movie theater
Hence:
6 km = 2.5 km + Distance from florist to movie theater
Distance from florist to movie theater = 3.5 km
The distance from florist to movie theater is about 3.5 km on the same street.

Our fathers brought forth on this continent a new nation.

Answer: </h3><h3>Fred has <u>20 students</u> and Lee has <u>22 students</u></h3>
=============================================================
Work Shown:
L = number of students in Lee's class
F = number of students in Fred's class
Lee has 1.1 times as many students compared to Fred
This means we have this equation
L = 1.1F
Whatever the value of F is, we multiply that by 1.1 to get the value of L
The two amounts L and F add to 42 total students
L+F = 42
1.1F + F = 42 .... replace L with 1.1F
2.1F = 42
F = 42/(2.1)
F = 20 .... Fred has 20 students
L = 1.1*F
L = 1.1*20
L = 22 .... Lee has 22 students
------------
Check:
L+F = 22+20 = 42
this confirms the answer
Answer:
Hey there!
There are 13 clubs in a deck of cards.
There are 4 tens.
However, the tens overlap with the clubs, so there are 16 cards to choose.
16/52=4/13
Let me know if this helps :)
Answer:
The upper limit for the 95% confidence interval for the population proportion of defective gaming systems is 0.022
Step-by-step explanation:
Upper Limit for 95% Confidence Interval can be calculated using p+ME where
- p is the sample proportion of defective gaming systems (
)
- ME is the margin of error from the mean
and margin of error (ME) around the mean can be found using the formula
ME=
where
- z is the statistic of 95% confidence level (1.96)
- p is the sample proportion (
- N is the sample size (1200)
Using the numbers we get:
ME=
≈ 0.007
Then upper limit for the population proportion is 0.015+0.007 =0.022
