Answer:
The area to the right of 2.120 is 0.0250 rounded to 4 decimal places
Step-by-step explanation:
We are required to find 
To find this area we have to use the t distribution. Also we can use technology like excel to find the area to the right of 2.120.
The excel function is:
=TDIST(2.120,16,1)=0.0250
Where:
2.120 is the value of the test statistic
16 is the degrees of freedom
1 denotes the one tailed.
Therefore, the area to the right of 2.120 is 0.0250
If they are all 5 dollars then it will be $15
The answer is 54 feet because 15+15+12+12=54
Hope this Helps :D
Answer:
Step-by-step explanation:
Answer:
The measure of angle N is 55°
Step-by-step explanation:
we know that
the law of cosines established
a² = b² + c² – 2*b*c*cos(A)
so
In this problem we have
a=ML=5.74 units
b=LN=4 units
c=MN=7 units
∠A=∠N=?
see the attached figure to better understand the problem
a² = b² + c² – 2*b*c*cos(A)------> cos (A)=[b²+c²-a²]/[2*b*c]
cos (A)=[4²+7²-5.74²]/[2*4*7]------> 0.57236
A=arc cos (0.57236)--------> A= 55°
therefore
The measure of angle N is 55°
