Find tan A. Can someone help me with this one??
marta [7]

Answer:

tan A = 5/12

Step-by-step explanation:

To find tangent of a triangle, it is this ratio : opposite / adjacent.

Knowing that "A" is the given angle, 5 is the opposite and 12 is the side adjacent to "A". Putting these values together, the tangent is

5 (opposite)/12 (adjacent).

Hope this helps!

Write each ratio as a fraction in lowest terms. 8 to 9​
3241004551 [841]

Answer:

8/17 and 9/17

Step-by-step explanation:

8:9

both add up to 17

so it can be 8/17 or 9 but it cannot be simplified unless if you want them both as a mixed number which is

8/17 as a mixed number is 2 1/17

9/17 as a mixed number is 1 8/17

A political pollster conducted a study to determine political party loyalty. To do so, he selected a random sample of 100 regist
Reika [66]

Answer: (a)

P - Value = 0.0981 is high, this indicates stronger evidence that we should fail to reject the null hypothesis: H0: pD = pR (There is no significant difference between the proportion of Democrats who plan to vote for the Democratic candidate in the upcoming election and the proportion of Republicans who plan to vote for the Republican candidate in the upcoming election). P - Value = 0.0981 is the probability of obtaining results at least as extreme as the observed results of the Hypothesis Test, assuming that the null hypothesis is correct.

(b)

Since P - Value = 0.0981 is greater than \alpha = 0.05, the difference is not significant. Fail to reject null hypothesis.

(c)

Since in the Hypothesis Test, we have failed to reject null hypothesis, we could have made: Type II Error: Failure to reject a false null hypothesis. One potential consequence of this error is as follows:

Suppose in reality there is significant difference between the proportion of Democrats who plan to vote for the Democratic candidate in the upcoming election and the proportion of Republicans who plan to vote for the Republican candidate in the upcoming election. But the political pollster wrongly concludes that there is no significant difference between the proportion of Democrats who plan to vote for the Democratic candidate in the upcoming election and the proportion of Republicans who plan to vote for the Republican candidate in the upcoming election. Type II Error is committed in this situation. The consequence of this Type II Error is that the political pollstar will that the political parties are loyal and will not do any follow up work whereas in reality it is not so.

Creating and solving formulas for geometric series:mastery test
Levart [38]

Answer:

D. y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}

Step-by-step explanation:

Let be y = \Sigma_{i = 0}^{4} \left[5\cdot \left(\frac{1}{3} \right)^{i}\right]. To find the equivalent expression we must use the following property:

y = c\cdot \Sigma_{i = 0}^{n} p(x) = \Sigma_{i=0}^{n} [c\cdot p(x)] (1)

Based on this fact, we find the following equivalence:

y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}

Hence, the correct answer is D.

HELP I WILL GIVE BRAINIEST
Zanzabum

Answer:

13.7

Step-by-step explanation:

It forms a triangle.

They are trying to find the height, cause they say the east-bound car went east so that makes the bottom of the triangle, the width. They also give is the distance in between both cars so that's the hypotenuse so let's set up the equation...

15² - 6² = 189

now we square root it

√189 = 13.7
