First problem:
The answer is C because theoretically it should have a 50% of landing
heads but instead it lands heads 56% of the time. Thus this is 6% higher
than 50%. It's not D because there is not specified detail of how the
person got this data so you can assume that the person did a fair
survey/data collection.
Second problem:
So in a data size of 490, 140 of them we trout. This means that 140/490 or 28.57% of the fish are trout. This means that in a sample size of 5000 fish, 5000*0.2857 or 1428.57 are trout.
Third problem:
The Science students seem to have a higher average score because the average score of Math students are:
(32+33+34+34+35+37+39+40+40)/9=36
average score of Science students are:
(41+42+43+43+46+46+47+49+49)/9=45.111
Step-by-step explanation:
The scientific notation of any number is given by :
![N=a\times 10^b](https://tex.z-dn.net/?f=N%3Da%5Ctimes%2010%5Eb)
a is any real no and b is any integer
The scientific notation of 345,000,000 should be
but Jorden wrote 34.5×10⁷. He is incorrect. He should have shifted decimal before 4 such that power of 10 becomes 8.
Answer:
B i think
Step-by-step explanation:
Answer:
b) exponential growth
Step-by-step explanation:
The value of an investment of $3,500 over "t" years at 4.5% interest is represented by the expression
![3500(1.045)^{t}](https://tex.z-dn.net/?f=3500%281.045%29%5E%7Bt%7D)
The general form of exponential expresion y = a.![b^{x}](https://tex.z-dn.net/?f=b%5E%7Bx%7D)
If exponent "x" is positive, then it is exponential growth. If exponent "x" is negative, then it is exponential decay.
Our given expression is in the form of exponent. Here the exponent "t" represents the number of years. It must be positive.
Therefore, our given expression is b. exponential growth.
Hope you will understand the concept.
Thank you.
