Answer:
0.95
Step-by-step explanation:
[tex]Correlation \ coefficient \ (r) = \dfrac{covaraince \ between \ X \ and \ Y }{SD_X \times SD_Y }[/tex]
[tex]Correlation \ coefficient \ (r) = \dfrac{15 }{10^{1/2} \times 25^{1/2} }[/tex]
[tex]Correlation \ coefficient \ (r) = \dfrac{15 }{3.162 \times 5 }[/tex]
[tex]Correlation \ coefficient \ (r) = \dfrac{15 }{15.81 }[/tex]
[tex]Correlation \ coefficient \ (r) \simeq 0.95[/tex]
Browning Montana holds the US record for the greatest temperature drop in one day. On January 23, 1916, the temperature changed by an average of -4.17 degrees per hour. To the nearest degree, what was the total temperature change after 24 hours???
Answer:
100°
Step-by-step explanation:
Average temperature change per hour = - 4.17° per hour
Total temperature change after 24 hours
Average temperature change per hour * 24

What are the steps to find the slope and y-intercept of the equation 16x - 4y = -32?
Answer:
slope = 4
y-intercept = 8
Step-by-step explanation:
First convert the equation into the form
y = mx + c
where m is the slope, and c is the y intercept
16x - 4y = -32
16x + 32 = 4y
4y = 16x + 32
y = 4x + 8
m = 4
c = 8
Answer:
Slope = 4
Step-by-step explanation:
16x - 4y = -32
-16x . -16x
-4y = -32 - 16x
/-4 . /-4
y = 8 + 4x

Use the properties of logarithms
Rewrite the following in the form log(c).
5log(2)
Answer: [tex]5\log(2)=\log(2^5)[/tex]
Step-by-step explanation:
According to the properties of logarithms, we have
To rewrite : [tex]5\log (2)[/tex] in the form of log(c).
Therefore,
[tex]\leq 5\log(2)=\log(2^5)[/tex] [[tex]\because\ n\log(m)=\log(m^n)[/tex]]
Hence, [tex]5\log(2)=\log(2^5)[/tex] .
