Step-by-step explanation:
we can find the length of other side by hypotenuse formula,
which is h² = a² + b²
so,
a = 157
b = 168
now after inserting the values we got,
→ h² = (157)² + (168)²
→ h = 24649 + 28224
→ h = 52,873
→ h² = √52873 = 229.94
so, length of other side is 229.94

<h2>
Answer with explanation:</h2>
Confidence interval for mean, when population standard deviation is unknown:
, where = sample mean
n= sample size
s= sample standard deviation
= Critical t-value for n-1 degrees of freedom
We assume the population has a normal distribution.
Given, n= 19 , s= 3.8 ,
A) Critical t value for and degree of 18 freedom
= 2.8784
B) Required confidence interval:
Lower bound = 19.9 years
Uppen bound = 24.9 years
C) Interpretation: We are 99% confident that the true population mean of lies in (19.9, 24.9) .
Graphs are used to represent real life situations
- Point (1, 0.75) represents 1 cookie costs $0.75
- Point (0,0) represents 0 cookie costs $0
The x and the y coordinates of the graph are used to represent the following variables
- x : The number of cookies
- y : The cost of the number of cookies
This means that:
Point (1, 0.75) represents 1 cookie costs $0.75 and point (0,0) represents 0 cookie costs $0
