Y=25000(1-0.63)^2<br> Find the decay rate.
Anestetic [448]

If I'm not mistaken.. the half-life should be 40,750 years.. so

y = 40,750


I got this by multiplying 25,000 by 1.63 and then if you divide by 2.. you get

20,375.. so one of those should be correct

What’s the answer for this one??
KIM [24]

Answer:

It is the second one.

Step-by-step explanation:

a and e are equal because they are mirrored. d and b are equal because they are on the same  line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.

A triangle has sides of lengths 4, 3, and 5. Is it a right triangle? Explain.
vlada-n [284]

Answer:

yes; 4² + 3² = 5²

Step-by-step explanation:

Pythagorean theorem.

In a right triangle the square of the hypotenuse is equal to  the sum of the squares of the other two sides. Hypotenuse is the longest side of the triangle.

4² + 3² = 5²

16 + 9 = 25

25 = 25

The manufacturer of Pepsi claims that its 2-liter bottles contain, on average, no more than 250 calories. A sample of 20 2-liter
Stels [109]

Answer:

Yes, Sample information does indicate that a 2-liter bottle of Pepsi contains more than 250 calories  

Step-by-step explanation:  

Null Hypothesis [H0] : u < 250  

Alternate Hypothesis [H1] : u > 250 {One Tail}  

t = (x' - u) / [ sd / √n ]  

= (255 - 250) / (5.6 / √20)  

5 / (5.6 /√20)  

= 3.99  

As t ie 3.99 > t value 1.65 ie for one tail 95% confidence level. So, we reject the null hypothesis & conclude that it contains more than 250 calories.
