Answer:
(0.5848 ; 0.6552)
We are confident that about 58% to 66% of sea foods in the country are Mislabelled.
No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.
Step-by-step explanation:
Sample size, n = 51
p = 0.62
1 - p = 1 - 0.62 = 0.38
n = 515
Confidence level = 90% = Zcritical at 90% = 1.645
Confidence interval = (p ± margin of error)
Margin of Error = Zcritical * sqrt[(p(1-p))/n]
Margin of Error = 1.645 * sqrt[(0.62(0.38))/515]
Margin of Error = 1.645 * 0.0214
Margin of Error = 0.035203
Lower boundary = (0.62 - 0.035203) = 0.584797
Upper boundary = (0.62 + 0.035203) = 0.655203
(0.5848 ; 0.6552)
We are confident that about 58% to 66% of sea foods in the country are Mislabelled.
No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.
x = x
Consider x. Let x be a quantity denoted in the real numbers equal to x. Now, some properties of the real numbers include closure under the four basic operations.
Answer: £200,000
Step-by-step explanation:
From the question, we are informed that the value of Rita's house increased by 5% and that her house then had a value of £210 000.
The value of Rita's house before the increase will be calculated as:
= 210,000 ÷ (100% + 5%
= 210000 ÷ 105%
= 210000 ÷ 105/100
= 210000 × 100/105
= £200,000
Answer:
1) 2x + 3x - 10 + 50 = 180
5x = 180 - 50 + 10 = 140
x = 140/5 = 28°
2) 3x + 15 + 4x + 5 + x = 180
8x = 180 - 15 - 5 = 160
x = 160/8 = 20°
Angle A = 3 (20) + 15 = 60 + 15 = 75°
3) x + 3x + 5x = 180
9x = 180
x = 20°
4) 48 + 2x = 180
2x = 180 - 48 = 132
x = 132/2 = 66°
5) 110 + 6x + 8x = 180
14x = 180 - 110 = 70
x = 70/14 = 5°
Angle C = 8 * 5 = 40°
