Answer:
Step-by-step explanation:
t1 means a1 and t7 means a7
a+(n-1)d=an
a+(1-1)d=4
so we get a as 4
<u><em>a=4</em></u>
a+(n-1)d=an
4+(7-1)d=22
4+6d=22
6d=22-4
d=18/6
<u><em>d=3</em></u>
Answer:
Step-by-step explanation:
Given that for a sample size of 25, sample mean = 102 lbs. and sample std deviation = 10 lbs.
(Right tailed test)
Given that we assume population is normally distributed
Test statistic:
Mean difference = +2
Std error of sample = 
t = test statistic = Mean diff/Std error 
degree of freedom
Critical value of t = 1.711
Our test statistic >1.71
Accept alternate hypothesis
Because there is significant difference between the test statistic and test statistic lies above critical value.
Answer:
701 is the answer you carry 9
Answer: 600 Feet squared
Step-by-step explanation:
Front + Back sides= 2 x 10 x 10=200
Left + Right sides= 2 x 10 x 10=200
Top + Bottom sides= 2 x 10 x 10=200
200+200+200=600
The scale of the drawing is 6 feet = 17 inches
Scaling is the process of increasing or reducing the size of a figure by a factor k.
In the given statement is:
Shane made a scale drawing of a hotel. a room in the hotel, which is 18 feet wide in real life, is 51 inches wide in the drawing.
A figure which is 18 feet wide in real life, is 51 inches wide in the drawing, hence the scale is:
Now, According to the question is
18 feet = 51 inches
Divide both sides by 3:
6 feet = 17 inches
Therefore, the scale of the drawing is 6 feet = 17 inches
