Answer:
38,200,000
Step-by-step explanation:
Put the 3 in the 8th spot to the left of the decimal point and fill in the other digits to the right of it.
38,200,000
__
The first spot immediately to the left of the decimal point has a place value of 10^0, so the location with a place value of 10^7 is the 8th spot left of the decimal point. You should be able to get the idea from the attached.
__
If you put your calculator in the appropriate display mode, it should show you the number in this form.
Answer:20
Step-by-step explanation:
The question is asking that X times 38% will equal to 247. So we set up the equation:
Then, we multiply both sides by
and we get the answer is
650
Answer:
D) -122
Step-by-step explanation:
Given:
We need to find f(-4).
Now by substituting the value of x =-4 in above equation we get;
By using PEDMAS we will solve for exponential function first we get;
Now we know that 
So we get;
Now using PEDMAS we will solve division.
Now using PEDMAS we solve multiplication.
Finally by subtraction we get;
Answer:
6 times we need to transmit the message over this unreliable channel so that with probability 63/64.
Step-by-step explanation:
Consider the provided information.
Let x is the number of times massage received.
It is given that the probability of successfully is 1/2.
Thus p = 1/2 and q = 1/2
We want the number of times do we need to transmit the message over this unreliable channel so that with probability 63/64 the message is received at least once.
According to the binomial distribution:
We want message is received at least once. This can be written as:
The probability of at least once is given as 63/64 we need to find the number of times we need to send the massage.
By comparing the value number we find that the value of n should be 6.
Hence, 6 times we need to transmit the message over this unreliable channel so that with probability 63/64.
