Answer:

2 + r = 7

Step-by-step explanation:

To write an equation for the image, simply look on both sides and add everything together. On the left side we have seven 1's, which adds up to 7. On the right side, we have 2 1's, which add up to 2, and a variable <em>r</em>. Now, we do not know the value of the variable <em>r</em>, so we simply leave it be. Therefore, the right side is equal to <em>2 + r</em>. Since the image represents a balanced equation, the left side must equal the right side.

Left side = 7

Right side = 2 + r

Left side = Right side

7 = 2 + r

2 + r = 7

Two of the airlines did not have an airline quality score. The least-squares regression line for this data is given by ŷ = 0.990
hjlf

Answer:

Step-by-step explanation:

the passengers of  hawaiian airlines  in 2018 were 1.800.000, and for Northwest airlines 192.500.000 (delta)

We replace this number in the equation :

Hawaiian : 0,990 +0.683 x (number of passengers) =

                  0.990 + 0.683 x (1.800.000) =12294012

Northwest airlines: 0,990 +0.683 x (number of passengers) =

                  0.990 + 0.683 x (195.000.000) = 131477501

These ordered pairs, {(2,4) (3,6) (4,8) (5,10)}, are a function.<br><br> True<br><br> False
ki77a [65]

Answer:

True

Step-by-step explanation:

In order for a relation (a set of ordered pairs) to be considered a <em>function</em>, every value in the <em>domain</em> (the set of all the first numbers in the pair) is associated with one value in the <em>range</em> (the set of all second numbers in the pair). This is easiest to see visually. Our domain is the set {2, 3, 4, 5} and our range is the set {4, 6, 8, 10}, and we can visualize the ordered pair (2, 4) as an "arrow" starting a 2 in the domain and ending at 4 in the range. When seen this way, a relation is a function if <em>every value in the domain only has one arrow coming out of it</em>. We can see from the attached picture that the ordered pairs in the problem are a function, so this statement is true.

The function y = –16t2 + 486 models the height y in feet of a stone t seconds after it is dropped from the edge of a vertical cl
Softa [21]
Since we are looking for the time it takes for the stone to hit the ground, then it means that we set the height y to 0 ft.

y = -16t² + 486
0 = -16t² + 486
16t² = 486
t² = 30.375
t = 5.51 seconds
