The answer is x=2
Remember, first add/substract the like terms, in this case 6x-10x to get -4x. Then, add 8x to negative 8x to cancel it out and do the same thing to -4x. Do this with all your terms and you should get 4x=8. Then divide both sides by 4 to get x=2.
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!

Answer:
91
Step-by-step explanation:
There are 13 scores in total,the Middle score is the median score.
Expanded Notation:
A. 654.362 = (6x100) + (5x10) + (4x1) + (3x0.1) + (6x0.01) + (2x0.001)
B. 125.384 = (1x100) + (2x10) + (5x1) + (3x0.1) + (4x0.01) + (8x0.001)
