They bought 5 trophies total
1st trophy cost $37.50
($18.50+$12.50+$4+$2.50=$37.50)
Each additional trophy cost $15
($12.50+$2.50=$15)
They spent $97.50 total
$97.50-$37.50=$60
Additional trophies $15
$15*X=$60
4 trophies=$60+$37.50 for 1st trophy
$60+$37.50=$97.50
Answer:↓↓↓
Step-by-step explanation:
We are given that side AB is congruent to <u>BD</u>. We are also given that side AC is congruent to <u>CD</u>.
We know that side BC and side <u>CB</u> are congruent because of the <u>Reflexive</u> property.
Therefore, ΔABC and Δ<u>DBC</u> are congruent because of <u>SSS Postulate</u>.
Hope this helped!

Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The population proportion is 
The margin of error is 
Given that the confidence level is 90%
Then the level of significance can be mathematically represented as
Next we obtain the level of significance from the normal distribution table the value is
Generally the sample size is mathematically represented as
![n = [ \frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * p(1- p )](https://tex.z-dn.net/?f=n%20%20%3D%20%5B%20%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%20p%281-%20p%20%29)
substituting values
![n = [ \frac{1.645 }{0.04} ]^2 * 0.45(1- 0.45 )](https://tex.z-dn.net/?f=n%20%20%3D%20%5B%20%5Cfrac%7B1.645%20%7D%7B0.04%7D%20%5D%5E2%20%2A%20%200.45%281-%200.45%20%29)
The generic form for this case is given by
y = m (x-xo) + yo
where
xo: x coordinate
me: y coordinate
Substituting the values we have
y = 5 (x-3) - 4
Therefore, the answer in this case is
y – (–4) = 5(x – 3)
