Step-by-step explanation:
The ratios in the table must be equivalent if it is to be filled in with something other than random numbers.
__
The second row is 10/4 = 2.5 times the first.
The first row is 4/10 = 0.4 times the second.
Answer:
CI 98 % = ( 3.332 ; 5.668 )
t(c) = 2.9979
Step-by-step explanation:
Confidence Interval CI 98 % then α = 2 % α = 0,02 α/2 = 0.01
Sample information:
Sample size n = 8
sample mean x = 4.5
standard deviation of sample s = 1.1 kg
degree of freedom df = n - 1 df = 8 - 1 df = 7
With α/2 0.01 and df = 7 from t-studente table we find t(c)
t(c) = 2.9979
CI 98 % = ( x ± t(c) * s/√n )
CI 98 % = ( 4.5 ± 2.9979 * 1.1/ √8 )
CI 98 % = ( 4.5 ± 3.2976/2.8228 )
CI 98 % = ( 4.5 ± 1.168 )
CI 98 % = ( 3.332 ; 5.668 )

Answer:
Step-by-step explanation:
Use the order of operations.
Note: PEMDAS or BODMAS stands for:
<u>PEMDAS</u>
- <u>Parentheses</u>
- <u>Exponents</u>
- <u>Multiply</u>
- <u>Divide</u>
- <u>Add</u>
- <u>Subtract</u>
<u>BODMAS</u>
- <u>Brackets</u>
- <u>Order</u>
- <u>Divide</u>
- <u>Add</u>
- <u>Subtract</u>
<u>First, do parentheses.</u>
3+6*(5+4)÷3-7
(5+4)=9
<u>Do multiply and divide.</u>
6*9=54
54/3=18
<u>Then, rewrite the problem down.</u>
<u>Add.</u>
- <u>Therefore, the correct answer is "C. 14".</u>

Answer:
the width is 470 ft and the length is 730 ft.
Step-by-step explanation:
Perimeter of a flag is 2l+2w
Let w = width
Let l = w+260
2(w+260)+2w=2,400
2w+520+2w=2400
4w+520=2400
4w=1880
w=470
So, the length would be 470+260, or 730
Therefore, the width is 470 ft and the length is 730 ft.
I hope this helped and have a good rest of your day!
