JKL is similar to PQR
so they want PR
JK
L is similar to
PQ
R
So PR is similar to JL
And they also give us the sides KL and QR
J
KL is similar to P
QR
Both of those sides are similar, so we can form a proportion.
Plug in the numbers:
Cross multiply:
Isolate PR
Simplify it
So your final answer is
If 1 inch represents 20 miles, then 5 inches should represent <em>5 times as many miles</em>, or 20 x 5 = 100 miles.
Answer: p-value of the test = 0.167
Step-by-step explanation:
Given that,
sample size n = 400
sample success X = 80
confidence = 95%
significance level = 1 - (95/100) = 0.05
This is the left tailed test .
The null and alternative hypothesis is
H₀ : p = 0.22
Hₐ : p < 0.22
P = x/n = 80/400 = 0.2
Standard deviation of proportion α = √{ (p ( 1 - p ) / n }
α = √ { ( 0.22 ( 1 - 0.22 ) / 400 }
α = √ { 0.1716 / 400 }
α = √0.000429
α = 0.0207
Test statistic
z = (p - p₀) / α
z = ( 0.2 - 0.22 ) / 0.0207
z = - 0.02 / 0.0207
z = - 0.9661
fail to reject null hypothesis.
P-value Approach
P-value = 0.167
As P-value >= 0.05, fail to reject null hypothesis.
Since test is left tailed so p-value of the test is 0.167. Since p-value is greater than 0.05 so we fail to reject the null hypothesis.
Given:
The system of equation is
To find:
Whether (3,4) is a solution of the given system or not.
Solution:
We have,
...(i)
...(ii)
Putting the value of y in (ii) from (i), we get
Divide both sides by -7.
Putting in (i), we get
So, the only solution of the given system is 
.
Hence, (3,4) cannot be a solution of given system, Hence the correct option is B.
