4 x 1.75 = 7 so that is the answer
Answer:
In mathematics, opposite number or additive inverse of any number is a number n which, if added to n, results in 0 (the identity element of addition). The opposite number for n is written as −n. For example, −7 is the opposite number of 7

Total number of cards in a deck = 52
Total umber of red cards = 13 + 13 = 26
P(red card)
= 26/52
= 1/2
Answer:
y = 2x -- Multiplicative: y is 2 times x.
y = x + 2 -- Additive: y is 2 more than x.
Step-by-step explanation:
The value of B1 shows a fall in demand as price rises by a unit. The point prediction is given as y = 306,560.8
<h3>How to solve the question using the intercept</h3>
The regression equation shows that y= 306,619-27.71.x
b1 = -27.71
The interpretation for b1 is that if the price of this good is increased by 1, then the demand for the good would fall by about 27.71.
<h3>The point prediction for demand</h3>
The regression line equation is given as
y= 306,619-27.71.x
when x which is price is = 2.10
Then the value of y would be:
y = 306,619 - 27.71*2.10
y = 306,560.8
c. a 95% C1 for B1 is given as:
1.96 * 27.71.
= 54.31
