The right triangle with sides 29m, 49.5m and 57.4 m has the value of cot φ as 1.707
<h3>What is a right angle triangle?</h3>
A right angle triangle has one of its angles as 90 degrees.
Therefore, it has an opposite, adjacent and hypotenuse side depending on the angle.
oposite side = 29 m
adjacent side = 49.5 m
hypotenuse side = 57.4 m
Therefore,
cot φ = 1 / tan φ
Hence,
tan φ = opposite / adjacent
Therefore,
cot φ = adjacent / opposite
cot φ = 49.5 / 29
cot φ = 1.70689655172
cot φ = 1.707

A, C, and D
A because for every 2 hours you're reading 200 pages.
C because for every 9 minutes, 1 second? (honestly that confuses me)
D because for every 2 mins you type 90 words

B
Step-by-step explanation:
-18 I'm pretty sure it is the right answer
Answer:
Test statistic = -2.44
There is enough evidence to support the strategist's claim.
Step-by-step explanation:
H0 : p = 0.41
H1 : p < 0.41
pˆ = 0.38
Test statistic :
z=pˆ−p/√p(1−p)/n
Z = (0.38 - 0.41) / √(0.41(1 - 0.41) / 1600
Z = - 0.03 / √0.0001511875
Z = - 0.03 / 0.0122958
Z = - 2.4399
Test statistic = -2.44
The Pvalue :
P(Z < -2.44) = 0.0073436
α - level = 0.02
If Pvalue < α ; Reject H0
0.0073436 < 0.02 ; We reject H0
Since Pvalue < α ; Hence, There is enough evidence to support the strategist's claim.
