We multiply 38 by 45 to get 1710. This is already in simplest form, although we can convert it to scientific notation as 1.71*10^3 if you wish.

Answer:
The area is 189 square meter.
Step-by-step explanation:
In this figure we have one square of 7 meter sides and one rectangle of 20 meter length and 7 meter of width.
Area of a square = side²
area of a rectangle = Length × width
Area of the square = 7² = 7 × 7 = 49 meter²
Area of the rectangle = 20 × 7 = 140 meter²
Area of the composite figure = 49 + 140
= 189 meter²
The area is 189 square meter.
The upper quartile is the numbers after the median and the lower is the numbers before the median. you find the median of each quartile
Answer:
(0.46, 0.52)
Step-by-step explanation:
The formula for Confidence Interval with Proportion
CI = p ± z × √p(1 - p)/n
Where
p = Proportion = x/n
x = 346
n = 706
p = 346/706
p = 0.49
z = z score of Confidence Interval 90% = 1.645
Therefore:
CI = 0.49 ± 1.645 × √0.49(1 - 0.49)/706
CI = 0.49 ± 1.645 × √0.49 × 0.51/706
CI = 0.49 ± 1.645 × 0.0188139843
CI = 0.49 ± 0.0309490042
Hence:
Confidence Interval is
0.49 - 0.0309490042
= 0.4590509958
≈ 0.46
0.49 + 0.0309490042
= 0.5209490042
≈ 0.52
Therefore , the confidence interval of the population proportion is
(0.46, 0.52)
