A)
acd = a + b
(Get the value of B from image)
136 = a + 56
(Subtract 56 from both sides)
136 - 56 = a
(Solve 136 - 56)
a = 80
(C is supplementary with 136)
136 + c = 180
(Subtract 136 from both sides)
c = 180 - 136
(Solve 180 - 136)
c = 44
Therefore:
a = 80 and c = 44
B)
egh = e + f
(Get values from image)
63 = e + 23
(Subtract 23 from both sides)
63 - 23 = e
(Solve 63 - 23)
e = 40
(G is supplementary with 63, supplementary angles equal 180
63 + g = 180
(Subtract 63 from both sides)
g = 180 - 63
(Solve 180 - 63)
g = 117
Therefore
e = 40 and g = 117
Answer:
50 pcs
Step-by-step explanation:
say
1000 pcs / $20
so 50 pcs / $
then
$10 * 50 pcs / $ = 500 pcs
Given that normally distributed data set has a mean of 55 and 99.7% of data fall between 47.5 and 62.5.
Let s be the standard deviation of data set.
Since 99.7% data fall within 3 standard deviations of mean, z-value for 47.5 and 62.5 has an absolute value of 3.
That is |z|=3
But z=
Let us plugin x=47.5 and mean =55 and equate it to 3.
That is
Since x is always positive ( being standard deviation),
Hence
We will get same value with 62.5 as well.
Hence standard deviation of data set is 2.5.
Answer:
x > -4
