Answer:
151, 152, 153
Step-by-step explanation: Add all three and it equals 465, and it follows the rules of consecutive numbers.
The regression equation which correctly models the data in this table is y = 1.49x - 107.5,
<h3>How to determine the regression equation?</h3>
From the table of data values, we have the following parameters:
∑x = 632
∑y = 404
∑x² = 80.142
∑xy = 51.448
Mathematically, the regression equation is represented by the following slope equation:
y = Bx + A
Next, we would determine A by using this expression:
A = (∑y·∑x² - ∑x·∑xy)/(n∑x² - (∑x)²)
A = (404×80,142 - 632×51,448)/(5×∑x² - (632)²)
A = (32,377,368 - 32,515136)/(5×80142 - 399,424)
A = -137,768/1286
A = 107.5
For B, we have:
B = (n∑xy· - ∑x·∑y)/(n∑x² - (∑x)²)
B = (5×51,448 - 632×404)/(5×∑x² - (632)²)
B = 1.49.
y = Bx + A
y = 1.49x - 107.5

Answer:
f(5)= 78.5. I hope this helps!!
Answer:
I think it is J if not it may be H if they are both wrong i am so so sorry
Step-by-step explanation:
Answer:7.3
Step-by-step explanation:
adjacent =x
Hypotenuse =16
Φ=63
From SOHCAHTOA
CosΦ=adjacent ➗ hypotenuse
Cos63=x ➗ 16
Cross multiply
16 x Cos63=x
16 x 0.4540=x
7.264=x
x=7.264
Nearest tenth x=7.3
