Answer:
$2.50
Step-by-step explanation:
Given the daily pay formula :
P(b)=5/2b+45
P(b) = employee’s total daily pay
b = number of bushels of peaches picked
Hence from the fórmula ; rate which employees are paid per bushel. Of peach picked is the gradient of the equation :
According to the intercept slope formula:
y = mx + c ; where m = slope or gradient
From the equation :
P(b)=5/2b+45
The slope or gradient is 5/2 ; hence, employees are paid $5/2 per bushel of peaches picked.
$5/2 = $2.50

Step-by-step explanation:
Hello!
A linear regression for the price of renting a room in a hotel and the rating said hotel received was calculated from a sample of n= 25 hotels.
The theoretical regression model is E(Y)= α + βXi
And the estimated regression equation is: ^Y= a + bXi
Where:
The estimator for the slope is b= 125
And the estimator of the Y-intercept is a= -400
So for this example the estimated regression line for the price of the hotel rooms given the ratings of the hotel is:
^Y= -400 + 125 Xi
^Y= represents the estimated average price of a hotel room
a= -400 is the estimated average price of a hotel room when the rating of the hotel is zero.
b= 125 is the modification of the estimated average price of a hotel room when the rating of the hotel increases one unit.
I hope this helps!
C²=A²+B²
C²= 7² + 24²
C²= 49 + 576
C²= 625
C=√625
C=25

Second Quartile ( designated Q2) also called the median or the 50th percentile (cuts data set in half ).
By the given scenario above, we can formulate two inequalities that best represent the scenario. We let x and y be the number of tables and chairs, respectively such that,
25x + 15y ≤ 285
x + y ≥ 16
The values of x and y if we temporarily change all the inequality signs to equal signs are 4.5 and 11.5, respectively. Since, it is not allowed for a number of item to be in negative, we can then say that the number of tables should be 4 and that of chair is 12.
