Answer:
Step-by-step explanation:
Neither one of the two given numbers are rational. sqrt(3)*sqrt(2) equals the square root of 6. All three numbers are irrational.
You can try it for yourself.
sqrt(2) = 1.4142
sqrt(3) = 1.732
1.4142 * 1.732 = 2.4493
sqrt(6) = 2.4493
The difference is a rounding error.
So the answer is B. sqrt(6) is totally irrational.
Answer:
5*sqrt(3)+sqrt(6)
Step-by-step explanation:
sqrt(3)*(5+sqrt(2))=5*sqrt(3)+sqrt(6)
Answer:
Step-by-step explanation:
<em>Step 1: Define significance level</em>
In this hypothesis testing problem, significance levels α is selected: 
, the associated z-value from Laplace table:
Φ(
) = α - 
=> = 
<em>Step 2: Define null hypothesis (</em>
<em>) and alternative hypothesis (</em>
<em>)</em>
: rate of flu infection 
= 8.3% or 8.3/100 = 0.083
: rate of flu infection < 8.3% or 8.3/100 = 0.083
<em>Step 3: Apply the formula to check test statistic:</em>
with 
is actual sampling percent, is rate of flu infection of , 
is number of samples.
The null hypothesis will be rejected if 
<em>Step 4: Calculate the value of K and compare with </em>
We have 
=>This is good evidence to reject null hypothesis.
=> The actual rate is lower. (As states)
Hope this helps!
