The table and graph shows the relationship between height (cm), x, and weight (kg), y. Which statements are correct?
-0)
A)
The value of r is about 0.67.
B)
This is a strong positive correlation
The equation 0.72539x + 53.05434 models the data.
B
D)
There is a linear relationship between height and weight.
E)
There is a tendency for high weights to be associated with high heights.

5x+2x=49

7x=49

x=7. 35 apples

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
