<span>The <u>correct answer</u> is:
This is the average number of days the house stayed on the market before being sold for $150,000.
Explanation<span>:
f(p) is defined as the average number of days a house stays on the market before being sold for price p (given in $1000).
We want f(150); this means p=150. Since p is in thousands of dollars, this means the price of the house was $150,000.
This means f(150) is the average number of days the house stayed on the market before being sold for $150,000.</span></span>
If 9 of the sparrows is 45% of the birds in the backyard, 9/x = 45/100.
Cross multiply to get 9 * 100 = 45x; simplified is 900 = 45x or 20.
This means that there are 20 birds in the backyard. You can check this by dividing 9/20 which equals 45%
Answer:
9.78083151 irrational
Step-by-step explanation:
Here, we want to sum 2/5 + √(88) and check if it is rational or irrational
2/5 = 0.4
√88 = 2 √22
So 0.4 + 2 √22
So what we want to do here is add a rational number to an irrational number. Kindly recall that surds are irrational numbers.
Mathematically, adding a rational number to an irrational one gives an irrational result
so we have;
9.780831519647 irrational
X-intercept has coordinates (x,0)
Y-intercept has coordinates (0,y)
So, the statement "<span> The ordered pair of x-intercept has a zero for the x-value" is false.
</span><span> The ordered pair of x-intercept has a zero for the y-value.</span>
Answer:
And the confidence interval for the difference is between:
Step-by-step explanation:
We have the following info given:
sample mean for medium Pizzas from Prim's
sample mean for medium Pizzas from Pizza Place
sample deviation for Prim's
sample deviation for Pizza Palca
sample size selected for each case
The confidence interval for the difference of means is given by:
And for the 95% confidence we need a significance level of 
and 
, the degrees of freedom are given by:
And the critical value would be
And replacing we got:
And the confidence interval for the difference is between:
