By using the Pythagoras theorem, the length of the ladder will be 13.6 feet.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Jennifer needs to use a ladder to clean a second-floor window on a building.
If the window is 13 ft above the ground and the base of the ladder is 4 ft from the building.
Then the length of the ladder will be
H² = 13² + 4²
H² = 169 + 16
H² = 185
H = 13.6 ft

Answer:
-2
Step-by-step explanation:
In a linear regression model we have the equation 
that relates 
and 
, where 
is the estimator of the slope and 
is the estimator of the Y-intercept. The coefficients and can be estimated with the equations:
. Thus,
Answer: 33.85
Step-by-step explanation: Add them up
Multiplying by 1/5 is the same as dividing by 5, so we can show a diagram of division. This can be done by constructing a horizontal line of length 30 cm and dividing it into 5 equal parts; each part will measure 6cm.
