Which interrogative pronoun best completes the sentence?

1/2expand the equation 1/2(3+4t-10)=

Ivanshal [37]

$\frac{1}{2} (3 + 4t - 10)$

$\frac{3}{2} + \frac{4t}{2} - \frac{10}{2}$

$(\frac{3}{2} - \frac{10}{2}) + 2t$

$\frac{ - 7}{2} + 2t$

$- 3.5 + 2t$

How could the relationship of the data be classified? scatter plot with points scattered going up to the right

Anettt [7]

Answer:

The correct answer is A. A fairly strong positive correlation

Step-by-step explanation:

Scatter Plot : A graph of plotted points that show the relationship between two sets of data.

Now, the points of the scatter plot are going up this shows the increase in the data points so we can say the correlation is positive.

Now, the direction of the scatter plots is to the right. So, we can say that the correlation is strong correlation.

Hence, the correct answer is A. A fairly strong positive correlation

Find (h-f)(x)???????

vichka [17]

Multiply both variables individually by the multiplied variable (x)... and you find yourself with -fx + hx.... Remember to bring that negative integer along too or the answere that I have without a negative integer won't count... I hope this clarified your understanding and question. As always good spiruts

g The downtime per day for a computing facility has mean 4 hours and standard deviation 0.9 hour. What assumptions must be true

Sedaia [141]

Answer:

To obtain a valid approximation for probabilities about the average daily downtime, either the underlying distribution(of the downtime per day for a computing facility) must be normal, or the sample size must be of 30 or more.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

In this question:

To obtain a valid approximation for probabilities about the average daily downtime, either the underlying distribution(of the downtime per day for a computing facility) must be normal, or the sample size must be of 30 or more.

The equation of the given line is....?

liq [111]

Answer:y=3x+3

Step-by-step explanation: the y-intercept is 3, and the slope is 3/1, which is 3. Technically the answer is not enough information, as it is not given how many units one square is.
