Answer:
Yes
Step-by-step explanation:
Given,
Population mean Z = 600
Sample mean, µ = 586.50
Size of the sample, n = 10
Standard deviation, σ = 26.77
The testing hypothesis is,
Null hypothesis = µ<600
Alternative hypothesis = µ≥600
The test statistics is the calculated value of Z,
(Z- µ)/(σ/√n)
= (600-586.50)/(26.77/√10)
= (13.5*3.1623)/26.77
= 42.691/26.77
= 1.5947
And at 5% level of significance, the table value of Z = 1.644
Here, calculated Z<Table value of Z, so we accept the null hypothesis.
So, the null hypothesis is accepted. The mean value of the laptop is less than 600.
Answer:
It will not taste the same bc there is too much oj.
Step-by-step explanation:
The recipe is saying that for every 4 cups of pineapple juice you put in, you must put in 5 cups of orange juice. That means if you put 8 cups of pineapple juice, you need 10 cups of orange juice, and if you have 12 cups of pineapple juice, you need 15 cups of oj. Obviously, 15 is less than 20. You are using too much oj, and because of this, it will not taste the same.
22' is 22 minutes
there are 60 minutes in 1 degree, how many in 22? well, the short answer is you divide it by 60, or 22/60 0.37 or thereabouts, so that makes it
121.037 degrees and 36''
36'' is 36 seconds, there are 60 seconds in 1 minute, so in short, just divide it by 60 as well, so 36/60 or 0.6 minutes
so, let us revise above some
121 degrees 22' and 36''
22' and 36'' is 22.6' because 36'' is 0.6'
how much is 22.6' in degrees? well 22.6/60
or about .38
so. 121° 22' 36'' will be 121.38° approximately
Answer:
22.14
Step-by-step explanation:
Using the Pythagorean Theorem:
a^2 + b^2 = c^2
21^2 + 7^2 = c^2
441 + 49 = c^2
490 = c^2 (square root both sides so c^2 becomes c)
c = 22.13594363 (round to hundredths)
c = 22.14
