Answer:
5.264 * 10^4
Step-by-step explanation:
We put a decimal point to the right of the number, so
52640.
Then we move it to the left until we get a number that is between 1 and 10.
5.2640
This was four hops to the left.
We can remove the trailing 0, and write
5.264 * 10^4
10^4 because of the four hops

Step-by-step explanation:The number of newly reported crime cases in a county in New York State is shown in
the accompanying table, where x represents the number of years since 2007, and y
represents number of new cases. Write the linear regression equation that represents
this set of data, rounding all coefficients to the nearest hundredth. Using this
equation, find the projected number of new cases for 2016, rounded to the nearest
whole number

This requires the pythagorean theorem :
a^2 + b^2 = c^2...where a and b are the legs and c is the hypotenuse..and by the way, this can only be used on right triangles
a^2 + b^2 = c^2
6^2 + 7^2 = c^2
36 + 49 = c^2
85 = c^2...take the sqrt of both sides, eliminating the ^2
sqrt 85 = c
9.22 = c....so the hypotenuse is approximately 9.22 units (thats rounded)
Answer:
The desired ordered pair is (1/2, 3/2).
Step-by-step explanation:
Let's use the substitution method here to determine either x or y first:
x = 5y - 7 (given). Then 5y - 7 can be substituted for x in x + 5y = 8:
5y - 7 + 5y = 8.
Combining like terms, we get 10y = 15, so that y = 3/2.
Find x by substituting 3/2 for y in x = 5y - 7: x = 5(3/2) - 7 = 15/2 - 14/2 = 1/2
The desired ordered pair is (1/2, 3/2).
