Weight of an object=J
x=J/(379.2/150)
x=J/2.528
y=12.64/2.528
y=5
Hope this helps :)
Hey go search math-way it’s an amazing algebra calculator give u all answers
Answer:
Options B, C, D & E do not comply with the rules for setting up hypotheses
Step-by-step explanation:
(A). H0: m = 100, Ha: m > 100.
These hypotheses fully complies with our rules.
B). H0: s = 20, Ha: s 20.
H0 is not an equality claim such as σ = 20. Hence, these hypotheses are not in compliance with our rules.
(C). H0: p -:: .25, Ha: p = .25
H0 should definitely contain the equality claim, although Ha contains it here. Thus, these are not legitimate and don't comply with our rules
(D)H0: m1 - m2 = 25, Ha: m1 - m2 > 100
The given value of 25 for m1 - m2 in H0 should also appear in Ha,but it does not do so here, so it doesn't comply with our rules.
E)H0: S2 = S2, H : S2 -:: S2
Each S2 is a statistic and so it does not belong in a hypothesis.
Yep! :) You got it.
The answer is 46.
Step-by-step explanation:
all we need to do is find the surface area, deduct windows and door areas.
that gives us the m² to be covered, which we have to multiply by $12.50 to get the total price.
what is the problem ? there are only trivial multiplications (with a calculator), additions and subtractions.
the house surface area is like for a box, but we don't care about the top and the bottom. only about the walls.
the "box" is 18 m × 14 m × 4 m.
so, the front and the back walls are each
18m × 4 m = 72 m²
both front and back : 2×72 = 144 m²
each side wall is
14m × 4m = 56 m²
both sides : 2×56 = 112 m²
now for the deductions.
each window is
1.5 × 2 = 3 m²
both windows : 2×3 = 6 m²
the door is
1 × 2.5 = 2.5 m²
so, the total area to "side" is
144 + 112 - 6 - 2.5 = 247.5 m²
to side 247.5 m² it costs
247.5 × 12.5 = $3,093.75
