Answer:

17) x = 58.1 units

18) x = 17 units

Step-by-step explanation:

The concept of similar triangles will be applied.

It is evident that the AAA congruence property is responsible for the similarity of the two triangles in the 2 cases. The theorem is

- Triangles are similar if the measure of all three interior angles in one triangle are the same as the corresponding angles in the other.

So, the corresponding sides from the two triangles can be written as a ratio of one another

17)

The most obvious tell here is the largest angle in the two triangles, the sides directly opposite this angle in the two triangles can be written in a ratio such that

(95.2/13.6) = 7

indicating that the bigger triangle is exactly 7 times the smaller one.

So,

(95.2/13.6) = (53.2/7.6) = (x/8.3) = 7

x = 7 × 8.3 = 58.1

18)

The obvious tell here is the smallest common angle for the two triangles, the two other corresponding sides can then be written in a ratio, matching the bigger side in the two triangles to each other.

(39.5/7.9) = (37.5/7.5) = (x/3.4)

(x/3.4) = 5 (Indicating thay the bigger triangle is 5 times bigger than the smaller one.

x = 3.4 × 5 = 17 units.

Hope this Helps!!!

Answer:

The probability plot of this distribution shows that it is approximately normally distributed..

Check explanation for the reasons.

Step-by-step explanation:

The complete question is attached to this solution provided.

From the cumulative probability plot for this question, we can see that the plot is almost linear with no points outside the band (the fat pencil test).

The cumulative probability plot for a normal distribution isn't normally linear. It's usually fairly S shaped. But, when the probability plot satisfies the fat pencil test, we can conclude that the distribution is approximately linear. This is the first proof that this distribution is approximately normal.

Also, the p-value for the plot was obtained to be 0.541.

For this question, we are trying to check the notmality of the distribution, hence, the null hypothesis would be that the distribution is normal and the alternative hypothesis would be that the distribution isn't normal.

The interpretation of p-valies is that

When the p-value is greater than the significance level, we fail to reject the null hypothesis (normal hypothesis) and but if the p-value is less than the significance level, we reject the null hypothesis (normal hypothesis).

For this distribution,

p-value = 0.541

Significance level = 0.05 (Evident from the plot)

Hence,

p-value > significance level

So, we fail to reject the null or normality hypothesis. Hence, we can conclude that this distribution is approximately normal.

Hope this Helps!!!
