Answer:
From the given data we need to use the following statistics rules
H0 x25
H1 x>25
t=4.355
Reject H0. The data does not suggest a significant mean difference in breaking load for the two fabric load conditions,option C is correct.
Using trigonometric identities, it is found that the sine and the tangent of the angle are given as follows:
.
<h3>How do we find the sine of an angle given the cosine?</h3>
We use the following identity:
In this problem, the cosine is:
Hence the sine is found as follows:
Second quadrant, so the sine is positive, hence:
<h3>What is the tangent of an angle?</h3>
The tangent is given by the <u>sine divided by the cosine</u>, hence:
Hence:

Answer: 178.3
Step-by-step explanation:
Use cos to find the value of x: cos(27)=350/x
You will find x = 392.81
Using this value, find sin(27): Sin(27)=y/392.81
You will find y=178.33
Rounding to the nearest tenth, you get 178.3
I believe they are all equivalent
Ex.). If angles A, B, and C are all complementary to an angle that is 30 degrees, then all three would be 60 degrees (60+30=90)
Answer:
x1=8 x2=-8
Step-by-step explanation:
since there is absolute , means any number inside that has negative value will become positive. so the answer is -8 and 8
sorry late reply :(
