In this equation, we are solving for f. The first thing we have to do is get rid of the denominator, so we have to multiply both sides by 9, which leaves us with 9C=5*(f-32). Then we divide both sides by 5, which is 9/5C=f-32. The last thing we have to do is add 32 to both sides to isolate f, which gives us our final equation of (5/9)C+32=f.
Answer:
(y-6)/6 = x
Step-by-step explanation:
y+4x=10x-6
Subtract 4x from each side
y+4x-4x=10x-4x-6
y = 6x-6
Add 6 to each side
y +6 = 6x-6+6
y+6 = 6x
Divide by 6
(y-6)/6 = 6x/6
(y-6)/6 = x
Answer:
D
Step-by-step explanation:
Since x is squared, that's a non-linear equation because it's the only answer that, when graphed, doesn't form a straight line
Answer:
The answer is false
Step-by-step explanation:
In a sample above 30 obs like this the confidence interval is defined as
X+- t* (s/sqrt(n)) where X is the mean t the tvalue for a given confidence level, n the size of sample and s standar deviation.
To find de appropiate value of t we must see the T table where rows are degrees of freedom and columns significance level
The significance is obtained:
significance = 1 - confidence level = 1 - 0.9 = 0.10
Degrees of freedom (df) for the inteval are
df = n - 1 = 18 - 1 = 17
So we must look for the value of a t with 17 values and significance of 0.10 which in t table is 1.740 not 1.746 ( thats the t for 16 df)
