Your answer can be two answer it can 126.12 or it can possibly be 96.80
Answer:
The 97% confidence interval would be from 108 to 165.
Step-by-step explanation:
Since the 78% confidence interval is from 87 to 133, to determine what the 97% confidence interval would be, the following calculations must be performed:
78 = 87
97 = X
97 x 87/78 = X
8.439 / 78 = X
108.19 = X
78 = 133
97 = X
97 x 133/78 = X
12.901 / 78 = X
165.39 = X
Thus, the 97% confidence interval would be from 108 to 165.
Answer:
B. 200
Step-by-step explanation:
A perfect square is the multiplication of two equal integers such as 1*1=1, 2*2=4, 3*3=9. From the examples, 1, 4, 9 are perfect square.
Non perfect square numbers are 1*2=2,
3*1=3,
5*1=5,
3*2=6,
6*1=6,
7*1=7
Examples of perfect squares:
1*1=1
2*2=4,
3*3=9,
4*4= 16,
5*5=25,
6*6=36,
7*7=49,
8*8=64,
9*9=81,
10*10=100,
11*11=121,
12*12=144,
13*13=169,
14*14=196,
15*15=225 and so on
Answer:
Hypotenuse≈![12.21](https://tex.z-dn.net/?f=12.21)
Step-by-step explanation:
≈![12.21](https://tex.z-dn.net/?f=12.21)
to calculate this you would need to find the square root of the first leg squared added to the second leg squared.
the hypotenuse is the longest side of the triangle
Salutations!
finding the 56th term is same as find the nth term, but its a bit more easier than finding the nth term.
we'll be using a formula to find the fifth term.
![a+(n-1)*d](https://tex.z-dn.net/?f=a%2B%28n-1%29%2Ad)
![a](https://tex.z-dn.net/?f=a)
stands for the first term (the first number in a sequence)
![d](https://tex.z-dn.net/?f=d)
is the difference between the constants
![n](https://tex.z-dn.net/?f=n)
is the what will be finding
so instead of n, we will be plugging in the number 56.
![a+(n-1)*d](https://tex.z-dn.net/?f=a%2B%28n-1%29%2Ad)
![23+(56-1)*-7](https://tex.z-dn.net/?f=23%2B%2856-1%29%2A-7)
we will be solving the brackets first
![23+55*-7](https://tex.z-dn.net/?f=23%2B55%2A-7)
![78-7](https://tex.z-dn.net/?f=78-7)
=71
the 56th term is 71
hope this helps!
have a great day!
