The scatterplot and trend line show a positive correlation between advertising costs and sales.
Using the points (6.4, 117) and (6.6, 120), what is the slope of the trend line?

When x = 6.4, y=117, therefore

15*6.4 + b = 117

b = 117 -  96 = 21

Confirm this value by checking (6.6, 120).

15*6.6 + 21 = 120 (Correct)

Answer: b = 21

Answer:

The real answer is 15.

Step-by-step explanation:

The kid above me thought they were smart using the old copy and paste method, and they did it from a completely different question. As you can tell, 21 isn't even an option, so 15 is the answer.

The plutonium isotope has half life
ratelena [41]

Answer:

Step-by-step explanation:

The different isotopes have different "half-lives" – the time it takes to lose half of its radioactivity. Pu-239 has a half-life of 24,100 years and Pu-241's half-life is 14.4 years. Substances with shorter half-lives decay more quickly than those with longer half-lives, so they emit more energetic radioactivity.

∠3 is a complement of ∠4, and m∠3=46°. Find m∠4.
Eduardwww [97]

Answer:

m < 4 = 44 degrees

Step-by-step explanation:

Here, we want to find the value of the given angle.

Mathematically, when two angles are complement of each other, they add up

to be 90 degrees. These angles are termed complementary angles.

Thus, by mathematical convention is this present case;

m <3 + m< 4 = 90

46 + m<4 = 90

m<4 = 90-46

m< 4 = 44 degrees
