The size of chicken at the form would be 111.8 inches.
Step-by-step explanation:
Given that,
The average height of cow = x1 = 4 feet 5 inches
x1 = 4 x 12 + 5 = 53 inches (12 inches in a feet)
The average height of chicken = y1 = 13 inches.
The height of cow statue at form = x2 = 38 feet
x2 = 38 x 12 = 456 inches
The height of chicken statue = y2 = ?
For this, the ratio of height in both the scenarios would be the same. Therefore,
x1/y1 = x2/y2
now, by putting the values
53/13 = 456/y2
y2 = (456x 13) / 53
y2 = 111.8 inches
Hence, the size of chicken at the form would be 111.8 inches.
40 because it seems to go up by 10's and only by one of the number it goes up
Answer:
0.89 g/cm³
Step-by-step explanation:
used the formula d=M/V
M is mass which is = 80g
V is volume which is = 90cm³
d = 80/90
d = 0.89 g/cm³
Answer:
95%
Step-by-step explanation:
For a given sample data, the width of the confidence interval would vary directly with the confidence level i.e. more the confidence level, wider will be the confidence interval.
This is because the critical value associated with the confidence level(e.g z value) becomes larger as the confidence level is increased which results in an increased interval.
The confidence interval for a population proportion is given by the formula:
So, for a fixed value of p,q and n, the larger the value of z the wider will be the confidence interval.
Hence 95% confidence interval will be wider than 80% confidence interval.
