Answer:
The lower quartile value is the median of the lower half of the data. The upper quartile value is the median of the upper half of the data.
<h3>Answer :- </h3>
- Let the three consecutive numbers be x -2 , x and x + 2
- Their sum = ( x - 2 ) + ( x + 2 ) = 3x
- This is the given equal to 54
- 3x = 54 or x = 54/3
- x = 18
<em>Thus </em><em>,</em><em> </em><em>the </em><em>required </em><em>numbers </em><em>are </em><em>1</em><em>6</em><em> </em><em>,</em><em> </em><em>1</em><em>8</em><em> </em><em>,</em><em> </em><em>2</em><em>0</em><em> </em>
p would be the number of parking meters that dont accpet nickels and the p^ would be the number of parking meters that accpet nickels
Log₄20-log₄ 45+log₄144=
log₄(20/45)+log₄144= (log_a b- log_a c=log_a (b/c) )
log₄[(20*144)/45]= (log_a b +log_a c=log_a (b*c) )
log₄(2880/45)=
log₄(64)=n ⇔ 4^n=64 (log_a x=n ⇔ a^n=x)
4^n=4³ ⇒n=3 (64=4*4*4=4³)
Answer: log₄20-log₄ 45+log₄144=3
Answer:
Confidence Interval = (23.776, 24.224)
Step-by-step explanation:
Restaurant chain claims that its bottles of ketchup contain 24 ounces of ketchup on average.
⇒ Mean = 24 ounces.
Standard Deviation = 0.8
Number of bottles used for sample = 49
⇒ n = 49
Confidence level = 95%
Corresponding z value with 95% confidence level = 1.96
Now, confidence interval is given by the following expression :

Hence, Confidence Interval = (23.776, 24.224)
