Answer:
Go to explaination for the details.
Step-by-step explanation:
a. A null Hypothesis : The production line fills the cartons as per standards, that is u=32.
Alternative Hypothesis: The cartons either under filled or over filled by the production line, that is u not equal to 32.
b. At given level of significance a, the data doesn't provide sufficient evidence to support the claim that the cartons either under filled or over filled by the production line.
c. At given level of significance a, the data provides sufficient evidence to support the claim that the cartons either under filled or over filled by the production line.
-3/5+5/6=d
-18/30+25/30=d
7/30=d
Answer:
10/4 <em>per</em> day (2.5 words simplified)
10/3 <em>days </em>he wrote so far (around 3 days simplified)
so in order to find out how much he wrote in total multiply the two numbers together
2.5 x 3 = around 7.5 or 8 words
Step-by-step explanation:
selling price of 1 kg oranges = rupees 80
so, selling price of 50 kg oranges :-
=》80 × 50
=》4000
now, profit = 800
so, Cost price (C.P) = selling price - profit
=》C.P = 4000 - 800
=》C.P = 3200
SO, purchasing rate per kg was
=》3200 ÷ 50 = 64
hence, purchasing rate = 64 rupees per kg
profit % =
=》
=》
=》
hence, profit % = 25%
Step-by-step explanation:
2x + 3y = 6
3y = -2x + 6
divide through by 3
y = (-2/3)x + 6............1
but equation of a straight line is
y = mx + c..............2
compare equation 1&2, m = -2/3 and c = 6
where m = gradient
c = intercept
