Answer:
Using Pythagoras theorem we can find the missing length.
5^2 + 13^2
25 + 169 = 194
√194 = 13.9283882772 = around 13
Answer:
A
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12 → A

What is the midpoint between( -4,-5 )and( 6,2)
Answers
Answer:
(1, -1.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x values and divide by 2
(-4+6)/2 = 2/2 = 1
To find the y coordinate of the midpoint, add the y values and divide by 2
(-5+2)/2 = -3/2 = -1.5

Situation: Find the substance's half-life, in days. Round your answer to the nearest tenth. A 33 gram sample of a substance that's used for drug research has a k-value of 0.1081. Enter the correct answer. N = Noe DONE No = initial mass (at time t = 0) 000 OO N = mass at time t k= = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
Answers
Answer:
1051 or..
10.51
Step-by-step explanation:
Since 33=30 and 0.1081 is supposed to be as a percentage since its already a decimal you could just round it and make it into a fraction then once you get the answer to the fraction it would either be 1081 since 0.1081 as a fraction is 1081/10000 or you could make into 10.81 as a decimal but after that you subtract "30 - 1,081" or 10.81 -30" either one of them and each of those numbers would give you the same exact number. Answer: 1051 or as a decimal 10.51

Step-by-step explanation:
Given that,

[tex]s = 5.2[/tex]
[tex]df=30-1[/tex]
[tex]=29[/tex]

By using the table, the critical values of t will be:

Now,
The confidence interval will be:
