Answer:
26.4 m
Step-by-step explanation:
The sine of an angle is the ratio between the opposite side of the angle and the hypotenuse. Hence,
sin 40° = 
= 
c = 
<u> c = 26.4 m (3 sf)</u>
Answer:
Step-by-step explanation:
a) 
b) Sample mean is the average of sample
c) std deviation of the sample
d) std dev/sq rt n
e) (sample mean - mu)/std error
f) p value = prob with test statistic
g) If p < alpha, reject H0.
h) If rejected, there is evidence that significant difference between population mean and sample mean.

Answer:
Step-by-step explanation:
An isosceles triangle needs to have 2 congruent sides to be considered a isosceles triangle. To find the length of AB use Pythagorean theorem :
a^2+b^2=c^2
substitute the triangle's lengths which are given and you get:
3^2 + 3 ^2= c^2
simplify and you get
c= √18
Repeat for AC and you get the same thing: √18.
AB=AC=√18. The triangle is an isosceles triangle because you have 2 congruent sides.
Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
so...
m = 0
b = -2
^^^Plug these numbers into formula
y = 0*x - 2
y = 0 - 2
y = -2
