Suppose you draw a line from the center of a clock face to the number 12. When the minute hand gets to 3 on the clock face, the

line and minute hand form a 90 degree angle. What angle does the line and the minute hand make when the minute hand is on 2?

Just divide 90 by three so whe it hits 3 its 90 then 2 is 60 degrees and the one is 30 degrees

alexandr402 [8]

Answer:

5 classes - 2 bass classes and 3 viola classes.

Step-by-step explanation:

Find the greatest common factor (GCF)

List the factors of 20 and 30:

20: 1, 2, 4, 5, 10, 20

30: 1, 2, 3, 5, 6, 10, 15, 30

The greatest factor that both numbers share is 10.

Therefore, there are 10 students in each class. So, she teaches 2 bass classes and 3 violas classes.

hope this helps! <3

An investigator wants to assess whether the mean m = the weight of passengers flying on small planes exceeds the FAA guideline o
stira [4]

Answer:

H_{0}: \mu= 185 and H_{a}: \mu > 185

Step-by-step explanation:

The null hypothesis H_{0} states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form H_{0}: parameter = value

In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form H_{0}: \mu= 185.

The alternative hypothesis H_{a} states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms

H_{a}: parameter > value\\H_{a}: parameter < value\\H_{a}: parameter \neq value

The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use H_{a}: \mu > 185 as his alternative hypothesis.

If you are working with less than, or greater than. If there is a negative do you switch the sign? For example 9t-4&gt;32
kirill [66]

Answer:

Rule:  If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.

Step-by-step explanation:

Your job here is to simplify 9t-4>32, in which the variable (t) is already positive.  Here you do NOT switch signs or reverse the direction of the inequality symbol.  Adding 4 to both sides, we get 9t > 36, or t > 4.

If, however, you had  -9t-4>32 to work with, the situation would be different because t in this inequality is negative.  Adding 4 to both sides results in:

-9t > 36.  To solve for t, we must divide both sides by -9 AND reverse the direction of the inequality symbol:

t < -4.

Rule:  If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.
