Blank divided by 7 is greater than 800
2 answers:
Answer:
The possible numbers for the blank are 5601, 8452, 93647 etc.
Step-by-step explanation:
Consider the provided information.
Blank divided by 7 is greater than 800
Let say the number should be in blank is x.
Now we need to find the value of x so that it divided by 7 gives a value greater than 800.
This can be written as:
Solve the above inequality for x.
The value of x should be greater than 5600.
We can select any number which is greater than 5600.
The possible choice for the blank are 5601, 8452, 93647 etc.
Note there are infinite number greater than 5600 so you can choose any of them.

Step-by-step explanation:
See attached picture.
First, compare the highest term of the dividend (x²) to the highest term of the divisor (x). We need to multiply the divisor by x.
When we do that, we get x² + 5x. Subtracting this from the dividend, we get -9x + 11.
Now repeat the process. Compare the highest term of the new dividend (-9x) to the highest term of the divisor (x). We need to multiply by -9.
When we do that, we get -9x − 45. When we subtract from the new dividend, we get 56.
So the quotient is x − 9, and the remainder is 56.
Answer:
D. A value of 0.9 is more than 2 standard deviations from the mean
Step-by-step explanation:
In the figure attached, the distribution of data is shown.
From the picture we can see that:
- The data has a standard deviation of 0.15 (= 0.5 - 0.35 = 0.65 - 0.5)
- The mean of the data is 0.5
- A value of 0.7 is more than 1 standard deviation of the mean.
- A value of 0.9 is more than 2 standard deviations from the mean (0.8 is 2 standard deviations from the mean)
