By applying the property of similar triangles, the distance Amana from point A to B walked is: B. 226 ft.
<h3>How to determine the distance?</h3>
By critically observing the diagram (see attachment), we can deduce that two (2) similar triangles were formed by the First Ave. and Second Ave.
By applying the property of similar triangles, the distance Amana walked is given by:
(AB + 113)/113 = (280 + 140)/140
(AB + 113)/113 = 420/140
(AB + 113)/113 = 3
AB + 113 = 3 × 113
AB + 113 = 339
AB = 339 - 113
AB = 226 ft.

Answer:
Step-by-step explanation
Answer:
4x^2-5x+1=0
=4x^2-x-4x+1=0
The second 4x is because of 5x=-x-4x
=xmultiply(4x-1)-4x-1)=0
=(4x-1)x(x-1)=0
=4x-1=0
Another value for x is
x-1=0
Final
=x=1/4
=x=1
Finally the answers are
Value of first X is
X=1/4
Value of second X is
X=1
20% x 5 = 100%
Depreciation means decreased of a value
Answer:
Step-by-step explanation:
<em>Step 1: Define significance level</em>
In this hypothesis testing problem, significance levels α is selected: 
, the associated z-value from Laplace table:
Φ(
) = α - 
=> = 
<em>Step 2: Define null hypothesis (</em>
<em>) and alternative hypothesis (</em>
<em>)</em>
: rate of flu infection 
= 8.3% or 8.3/100 = 0.083
: rate of flu infection < 8.3% or 8.3/100 = 0.083
<em>Step 3: Apply the formula to check test statistic:</em>
with 
is actual sampling percent, is rate of flu infection of , 
is number of samples.
The null hypothesis will be rejected if 
<em>Step 4: Calculate the value of K and compare with </em>
We have 
=>This is good evidence to reject null hypothesis.
=> The actual rate is lower. (As states)
Hope this helps!
