Answer:

12 300

Step-by-step explanation:

The way that I would do this, is first doing 7*300. That would result in 2100.

Next would be doing 7*12. Resulting in 84.

Finally you would add 2100 and 84 which is very simple just 2184.

If 300 looks like a tough number to multiply, just do 7*3 then add two 0's to the end.

The increase in a person’s body temperature T(t), above 98. 6ºF, can be modeled by the function T (t) = StartFraction 4 t Ove
kvv77 [185]

The meaning of the horizontal asymptote for the given function is that;

The horizontal asymptote of y = 0 means that the person’s temperature will approach 98.6ºF as time elapses

We are told the increase in a person's body temperature above 98.6°F can be modeled by the function;

T(t) = 4t/(t² + 1)

Where;

t represents the time elapsed

Now, let us find a way to simplify the function so that t at the numerator is removed.

Thus, we will now have;

4t/(t² + 1) = 4/(t + (1/t))

To get the horizontal asymptote, we have to find the limit of the function as t approaches infinity.

Thus;

Lim t ➡ ∞ gives;

T(∞) = 4 × 1/(∞ + (1/∞))

T(∞) = 4 × 0

T(∞) = 0

This means that y = 0 is the horizontal asymptote of the function.

Thus, in conclusion The horizontal asymptote of y = 0 means that the person’s temperature will approach 98.6ºF as time elapses

Part-time weekly earnings ($) by college students.
alexira [117]

Answer:

There is a significant linear correlation between the two variables.

Step-by-step explanation:

Given that part time weekly earnings are

x y

 

10 93

15 171

20 204

20 156

35 261

 

 

 

Correlation 0.9199

H0: r=correlatin =0

Ha: r ≠0

(two tailed test)

r difference = 0.9199

t = r*\sqrt{(n-2)/(1-r^2)} \\=4.063

p value < 0.0001

Since p <0.05 we reject null hypothesis

There is a significant linear correlation between the two variables.
