Answer:
D. x=29.37
Step-by-step explanation:
To answer this question you have to understand how log work. Log is the abbreviation of logarithm and it works as an inverse function of exponentiation.
The rules should be like this:
Variable a in the equation is called base. If it left empty you can assume its base 10. The log in this question using 5 as a base. Variable b will be x and variable c will be 2.1
Now, let's change the variable of the equation using the information from the question.
3(x+3)= 8-2x
3x +9 = 8 - 2x
3x + 1 =-2x
1 = -5x
x = -1/5
no
Answer:
No, because the radicands are not the same
Step-by-step explanation:
Answer:
small=2, large=8
Step-by-step explanation:
let every candle holder(small) hold x candle and large y.
=>east side= 10x+4y=52-equation 1
=>west side=2x+4y=36-equation 2
equation 1 - equation 2=10x+4y-(2x+4y)=52-36
=>10x-4y-2x-4y=16
=>8x=16
=>x=16/8=2 candles
therefore, every small candle holder has 2 candles.
for large candle holders' capacity=> 2*2+4y=36
4+4y=36
4y=32
y=32/4=8 candles

Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%
According to the empirical rule :
