Answer:

Step-by-step explanation:
In any triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse, or longest side, of the triangle (o/h).
Therefore, we have:

Answer:
y = 3x + 7
(Not sure what the question was so, I just put it in slope intercept form)
Step-by-step explanation:
Let x be Steve's age.
Steve = x
Steve's Mom = y
Now let's create an equation:
y - 7 = 3x
y = 3x + 7
(Not sure what the question was so, I just put it in slope intercept form)
Please let me know if I misunderstood the question that way I can help you! <3
Answer:
The test statistic (z-score) of this one-mean hypothesis test is z=1.823.
Step-by-step explanation:
The null and alternative hypothesis are:

The significance level is 0.05.
The sample size is n=22.
The sample mean is M=157.
The standard deviation is 18.
The z-score can be calculated as:

The test statistic (z-score) of this one-mean hypothesis test is z=1.823.
It is valid.
The three angles must add up to 180. So, if one is more than 90, the other two have to be less than 90.
