1st photo is simplifying the entire account.
2nd photo is how i simplified the x^2 + 9x + 18 equation into (x+3).(x+6) .
3rd photo is the remaining part of the 2nd photo.
Answer: 2nd option = (x+6)(x+5)
3%
Answer:
Selling price with VAT {15%} = Rs 41400
S.P +15% of S.P =Rs 41400
S.P(1+15%)=Rs 41400
S.P=Rs 41400/1.15
Selling price without VAT =Rs 36000
Again
Discount = 10%
M.P =S.P+ Discount % of M.P
M.P-Discount% of M.P= S.P
M.P(1-Discount%)=Rs 36000
M.P(1-10%)=Rs 36000
M.P=Rs 36000/0.9
Marked Price = Rs 40,000
again
Discount =Discount % of M.P
=10% of 40000
=Rs 4,000
Again
Profit=20%
For 20% profit
Cost price = (S.P*100)/(100+profit%)
=(36000*100)/(100+20)
= Rs 30000
For 24% profit
selling price = (100+profit%)*C.P/100
=(100+24)*30000/100
=Rs 37200
Again
Discount = 40000–37200 = Rs2800
Discount % = discount/M.P*100%
=2,800/40,000* 100 = 7%
Finally
Discount percent to be reduced =10%–7%= 3%
Answer:
g(10) = 21
g(0) = 1
g(10) = 21
g(22) = 45
g(28) = 57
g(16) = 33
Step-by-step explanation:
g(x) = 2x + 1
Then in order to find g(10), replace x over 10
g(10) = 2(10) + 1
g(10) = 20 + 1
g(10) = 21
so g(10) = 21
keep doing this to all of the problems and it should be answered the same way.
Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
The GCF is: 2x^2a
Hope this helps!
