Answer:
1
Step-by-step explanation:
For any triangle, you only need to know 3 pieces of information out of the 6 angles and sides to solve for the rest of the triangle.
Answer:
Step-by-step explanation:
each box has 12 melon for 15 dollars:
the price of one melon : 15/12=1.25 dollar each
he bought 12 boxes of melon and paid 15 dollars for each :
12*15=180 dollars
total melon is : 12*12=144 dollars
he sold 3/4 of a melon : 3/4 *144=108
the cost of 108 : 108*1.25= 135 dollars
at a price of $ 1.6 = 108*1.6= 172.8
the rest of the melon sold at reduce price=
144-108= 36
over all profit = 15 %
180*(1+0.15)=207 dollars profit
selling 108 melons : $172.8
overall profit - profit from selling 108 melons: 207-172.8=$34.2
<h2>reduced price = 34.2/36=0.95 dollars</h2>
EQUATIONS:
24x + 32y = 264
x + y = 9
x is shirts, y is pants
SOLVING by substitution:
x = 9 - y
24(9 - y) + 32y = 264
216 - 24y + 32y = 264
8y = 48
y = 6
x + 6 = 9
x = 3
Answer:
Answer : (0.1183 ≤ p ≤ 0.3103)
Step-by-step explanation:
Solution :
Given that,
a) n = 70
x = 15
Point estimate = sample proportion (p)= x / n = 15 / 70 = 0.2143
1 - p = 1 - 0.2143 = 0.7857
At 95% confidence level
α = 1 - 95%
α =1 - 0.95 =0.05
α/2 = 0.025
Zα/2 = Z0.025 = 1.960
Margin of error = E = Zα / 2 * √ (( p * (1 - p )) / n)
= 1.96 (√((0.2143 * 0.7857) / 70)
= 0.096
A 95% confidence interval for population proportion p is ,
P - E ≤ p ≤ P + E
0.2143 - 0.096 ≤p ≤ 0.2143 + 0.096
(0.1183 ≤ p ≤ 0.3103)
