Answer:
0.0060
Step-by-step explanation:
The z-score is given by
<em>z = (866,475-722,500)/57,429 = 2.51
</em>
The probability is given by the area under the Normal curve N(0,1) to the <em>right</em> of 2.51
In <em>Excel </em> this value is found with the formula
=1-NORMDIST(2.51,0,1,1)
and in <em>OpenOffice Calc
</em>
=1-NORMDIST(2.51;0;1;1)
<em>
(NORMDIST(2.51;0;1;1) gives the area to the left of 2.51, so 1-NORMDIST(2.51;0;1;1) gives the area to the right of 2.51)
</em>
and equals 0.0060
Answer:
It would be 63 if he traveled 315 miles in 5 hours
Step-by-step explanation:
He was traveling 63 mph

Answer:
The area of each square is 16 square units.
Step-by-step explanation:
Given,
The two squares are identical.
Hence, their areas are of the same values.
Area of square 1:
Area of square 2:
As, their areas are equal,
Therefore,
Answer:
8 bags of rye & bluegrass mix
10 bags of bluegrass
Step-by-step explanation:
RB = bags of rye & bluegrass mix
B = bags of bluegrass
348B + 255RB = 5334
RB+B = 18 then RB = 18-B
substitute for RB
348B + 255(18-B) = 5334
348B + 4590 - 255B = 5334
reduce
93B = 744
B = 8
RB = 10
Y - y₁ = m(x -x₁)
slope m = -2, from point (10, -9) , x₁ = 10, y₁ = -9
y - y₁ = m(x -x<span>₁)
</span>y - -9 = -2(x - 10<span>)</span><span>
y + 9 = -2(x - 10) </span>
