It snowed 57.5 in Big Bear
Because 15% of 50 is 7.5 and 50+7.5=57.5
Hope this is helped
Answer: 120 ft
Step-by-step explanation:
The question simply wants us to find the perimeter of the rectangle. The dimensions of the rectangle space have been given as 36ft by 24ft, to calculate the amount of fencing Chris need to buy will be:
Perimeter of a rectangle= 2(l+w)
where, l = length
w = width
Perimeter= 2(l+w)
= 2(36+24)
= 2 × 60
= 120ft
Chris needs to buy 120ft of fencing.
Answer:
P-value ≈ 0.3463
Step-by-step explanation:
Hypothesis test would be
:p=0.20
:p>0.20
We need to calculate the z-score of sample proportion and then the corresponding P-value.
z-score can be calculated as:
z= where
- p(s) is the sample proportion of specimens yield before the theoretical point ()
- p is the proportion assumed under null hypothesis. (0.20)
- N is the sample size (40)
Using the numbers
z= =0.3953
and the P-value is then P(z)≈0.3463
Its 2x +20
