I conclude the triangle is acute
Answer:
C = 13
Step-by-step explanation: According to the pythagorean theorem, which states A² + B² = C². This means that in this equation 5²+12²=x². When we solve this we get 169=x². Since 169 is the perfect square of 13 therefore the answer is 13.
Answer:
a: no the sample size is too small
b: Yes, the distribution is normal with a mean of 40 and standard deviation of 12
Step-by-step explanation:
a: If n < 30, we need to know that the sample is normally distributed or else we can't determine anything. When sample sized get very large, they usually resemble normally distributed data sets so we can still make conjectures even if the data isn't officially normally distributed
b: The question tells us that the sample is normally distributed, so even though n < 30, we can still make conjectures about the population
Answer:
$255,331
Step-by-step explanation:
Calculation for the estimated price
ln (price) =11.65 +0.000473*square foot
Square feet =1,692
First step is to find the ln (price)
ln (price) =11.65 +0.000473*1,692
ln (price)=12.450316
Last step is to calculate the Estimated price by using calculator to find the exponential of 12.450316
Estimated price=e^(12.450316)
Estimated price=$255,330.99
Estimated price=$255,331 Approximately
Therefore the estimated price of a house that is 1,692 square feet will be $255,331
