Answer:
7π/6
Step-by-step explanation:
The way to convert radian to degree is to convert π to 180 degrees. We know that π radian is equal to 180 degrees and therefore.
A) 7(180)/6 = 7(30) = 210 degrees
B) 6(180)/7 = 1080/7 = approx 154.2 degrees
C) 7(180)/3 = 7(60) = 420 degrees
D) 3(180)/7 = 540/7 = approx 77.1 degrees
When we convert π rad to 180 degrees and evaluate, we will get the rad value in degree form.
Therefore, 7π/6 = 210 degrees. Hence, A is the answer.
Answer:
plane = 250mi/hr
wind = 5mi/minute
Step-by-step explanation:
speed = distance/time
plane = 1000miles/4hour
wind = 1000miles/200minutes
Its asking you to draw rectangles with sides that equal 30 cm for example
The we should use ANOVA instead of several t-tests to evaluate the differences in the mean of three or more groups.
<h3>What is t test?</h3>
A t- test is a measurable test that is utilized to look at the method for two gatherings. It is many times utilized in speculation testing to decide if a cycle or treatment really meaningfully affects the number of inhabitants in interest, or whether two gatherings are not quite the same as each other.
<h3>Explain ANOVA test:</h3>
The ANOVA test permits an examination of multiple gatherings simultaneously to decide if a relationship exists between them.
<h3 /><h3>According to question:</h3>
We ought to utilize ANOVA rather than a few t-tests to assess the distinctions in the mean of at least three gatherings on the grounds that without fail, we direct a t-test (between two gatherings) there is some opportunity that a Kind I blunder is being made while doing the test.
