Step-by-step explanation:
1 kg = 1000g
2.26kg = 2260g
Kilograms left = 2260 - 450 = 1810g
1810g or 1.81kg will be left
Answer:
Step-by-step explanation:
P= 2(L) + 2(w)
1504= 2(525) + 2(w)
1540= 1050 + 2(w)
1540 - 1050= 2(w)
490 = 2(w)
490/2 = w
245 = w
w is y
L is 525
Answer:
4.1 shirts
Step-by-step explanation:
Mean can be found by adding all data points and dividing that by the total amount of data points.
There are 12 students selling shirt, which gives you 12 data points.
So (3+4+8+5+2+5+0+5+3+4+3+7)/12 = 4.083...
Which rounds to 4.1 shirts
Answer:
The answer is -1.2
Step-by-step explanation:
Recalling the standard deviation formula,
we have : σ = sqrt[ P * ( 1 - P ) / n ]
Where sqrt = square root
n = Number of derivative
Therefore,:
if, H0: p is not 48% vs H1: p1 = 48%
standard deviation is:
σ = sqrt[ P * ( 1 - P ) / n ] = sqrt[ .48*.49/900 ] = .01666333+
z -score is (p-P)/σ
= (.51-.53)/.01666333
The answer therefore = -1.2
ICONCLUSION:
It can therefore be concluded that there is statistical evidence that the proportions are different. H0 accepted in the hypothesis.
