Answer:
x > 4
Step-by-step explanation:
For this problem we just have to add the underground growth(1.25) to the above ground growth(8.5)
1.25+8.5= 9.75 units
The 7 is in the thousands place, the 8 is in the hundreds place, the 5 is in the tens place, the 2 to the left side if re decimal point is in the ones place, the 2 to the right side of the decimal point is in the tenths place, the 0 is in the hundredths place, and the 9 is in the thousandths place.
Using a calculator, it is found that the correlation coefficient is of 0.997.
<h3>What is a correlation coefficient?</h3>
It is an index that measures correlation between two variables, assuming values between -1 and 1.
If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
In this problem, we have the data-set for the weight and for the height. To find the coefficient, we insert each data-set in the calculator. Doing this, we find that the coefficient is of 0.997.

Sinα=h/s
h=ssinα
h=50sinα
dh=h(45)-h(25)
dh=50(sin45-sin25) feet
dh≈14.2 ft (to nearest tenth of a foot)
