Answer:

1. 0.82x

2. 1.18x

3. (7/10)x

4. (3/10)x

Step-by-step explanation:

When something is discount off 18 percent, it lowers the orginal price by 18 percent. Pretend the original price is x. Taking out 18 percent would be 0.82x

Same thing. 18 percent more, would be 1.18x since instead of subtracting, you add. 1.18x

3/10 in percent form is 30 percent. 100 - 30 = 0.7 so 0.7x

Since it has 3/10 <em>of </em> the orginal, it is multiply. If the orginal is x, x * 3/10 = (3/10)x.

Assuming that the sample mean carapace length is greater than 3.39 inches, what is the probability that the sample mean carapace
joja [24]

Answer:

The answer is "".

Step-by-step explanation:

Please find the complete question in the attached file.

We select a sample size n from the confidence interval with the mean \muand default \sigma, then the mean take seriously given as the straight line with a z score given by the confidence interval

\mu=3.87\\\\\sigma=2.01\\\\n=110\\\\

Using formula:

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}  

The probability that perhaps the mean shells length of the sample is over 4.03 pounds is

P(X>4.03)=P(z>\frac{4.03-3.87}{\frac{2.01}{\sqrt{110}}})=P(z>0.8349)

Now, we utilize z to get the likelihood, and we use the Excel function for a more exact distribution

=\textup{NORM.S.DIST(0.8349,TRUE)}\\\\P(z

the required probability: P(z>0.8349)=1-P(z

jasenka [17]

Answer:

f(y) = 12 + 4x

Step-by-step explanation:

Output is 12 more than 4 timea the input

The dependent variable = y

The dependent variable = x

The input is the independent variable, x

Output is the dependent variable, y

Output = 12 + (4 * input)

Hence, the function rule can be written has :

f(y) = 12 + 4x
