Step-by-step explanation:
<u>Answer</u>
$1,400
<u>Explanation</u>
The original price = 100%
After the discount the selling price = (100-25)=75% of the original price.
75% ⇒ $1050.00
100% ⇒ ?
From here you cross multiply
Original price = (100% × $1050.00)/75%
= 105,000/75
= $1,400
Answer:
There are 30 days according to the Georgian calender of the month of april.
Step-by-step explanation:
Answer:
115 boys
131 girls
Step-by-step explanation:
Given data
The given ratio= 27:31
The sum of the ratio = 27+31= 58
The total number of students taking geometry= 246
Let us apply the part to all method
let the number of boys be x
27/58= x/246
cross multiply
58*x= 246*27
58x=6642
x= 6642/58
x=114.5
Hence the number of boys is 115
Thefore, the number of girsl= 246-115= 131
You want to find Pr[-2 < <em>Z</em> < -1].
The table tells you that
• Pr[<em>Z</em> < 0] = 0.5000
• Pr[<em>Z</em> < 1.00] = 0.8412
• Pr[<em>Z</em> < 2.00] = 0.9772
• Pr[<em>Z</em> < 3.00] = 0.9987
We have
Pr[-2 < <em>Z</em> < -1] = Pr[<em>Z</em> < -1] - Pr[<em>Z</em> < -2]
(because the distribution of <em>Z</em> is continuous)
… = Pr[<em>Z</em> > 1] - Pr[<em>Z</em> > 2]
(by symmetry of the distribution about its mean)
… = (1 - Pr[<em>Z</em> < 1]) - (1 - Pr[<em>Z</em> < 2])
(by definition of complement)
… = Pr[<em>Z</em> < 2] - Pr[<em>Z</em> < 1]
… = 0.9772 - 0.8412
… = 0.1360 ≈ 0.14 … … … (B)
