Answer:
Step-by-step explanation:
Set up null and alternate hypothesis
H0: p =0.05
Ha: p>0.05
(One tailed test at 5% level)
Sample size n =384
Sample proportion p = 46/384 =0.1198
p difference = 0.1198-0.05 =0.0698
Std error = 
Test statistic = 4.23
p value = 0.000012
Since p<0.05, we reject null hypothesis
There is more than 99.95% probability that proportion is more than 0.05
We accept the claim that the risk has increased.
Answer:
40.8 yd
Step-by-step explanation:
From SOH CAH TOA, you know that the relationship between the adjacent side (distance to tower) and opposite side (height of tower) of the relevant triangle is given by ...
... tan(11°) = (height of tower)/(distance to tower)
Multiplying by the denominator, we have ...
... height of tower = (distance to tower) × tan(11°)
... = (210 yd) × 0.19438 ≈ 40.82 yd
Rounded to the nearest 0.1 yd, the height is 40.8 yd.
Distributive property
this ia the answer
Answer:
In the equation t is the amount of time in seconds. The -2.4 is the distance it travels in 1 second.
-2.4 x 5 seconds= -12 meters.
The anchor dropped 12 (-12) meters in 5 seconds.
