Answer: 1100
Step-by-step explanation: mark x for the total sum.
0.35x+ 0.20x + 495 = x. 495= x-0.35x-0.20x
495= 0.45x. X= 495/0.45
Answer: a. 0.1031; fail to reject the null hypothesis
Step-by-step explanation:
Given: Significance level : 
The test statistic in a two-tailed test is z = -1.63.
The P-value for two-tailed test : 
[By p-value table]
Since, 0.1031 > 0.05
i.e. p-value > 
So, we fail to reject the null hypothesis. [When p< then we reject null hypothesis ]
So, the correct option is a. 0.1031; fail to reject the null hypothesis.
Ken:
Ken's Age = 18
Elizabeth:
Elizabeth's Age = 2/3 x Ken's age
Elizabeth's Age = 2/3 x 18
Elizabeth's Age = 12
Clint:
-Note: At Clint's <em>next</em> birthday. So we need to subtract 1 from the age.
Clint's Age = (2 x Elizabeth's Age) - 1
Clint's Age = (2 x 12) - 1
Clint's Age = 24 - 1
Clint's Age = 23 right now
Hope this helps!! :)
Answer:
1.
Step-by-step explanation:
1) if sin30=0.5; tan45=1; tan30=1/√3; sin60=√3/2, then
2) 0.5+0.5=1.
The right answer is the third one.
