Answer:

The regression line is not a good model because the residuals are not randomly distributed.

Step-by-step explanation:

In a regression, the residual is the difference between the observed values and the predicted values.  

If the points in a residual plot are randomly dispersed, a linear regression model is appropriate for the data.

In this case, a pattern is present (the plot is similar to a sine plot); this suggest that a non-linear regression would be better.

Applying properties to write equivalent expressions for 2x+5y+5(2x+5y)
levacccp [35]

Solving expression 2x+5y+5(2x+5y) we get 12x+30y

Step-by-step explanation:

We need to solve the expression:

2x+5y+5(2x+5y)

Solving:

Multiplying 5 with terms inside the bracket:

2x+5y+5(2x+5y)\\=2x+5y+10x+25y\\Combining\,\,like\,\,terms:\\=2x+10x+5y+25y\\=12x+30y

So, Solving expression 2x+5y+5(2x+5y) we get 12x+30y

The manager of a snack bar buys bottled water in packs of 35 and candy bars in packs of 20. Then, she sells the items individual
hoa [83]

Answer:

8 packs of bottled water and 14 packs of candy bars

Step-by-step explanation:

Provided,

Each pack of water bottles = 35 bottles

Each pack of candy = 20 candy

Since quantity of candy in each pack is small than quantity of water bottle in each pack, in order to have same quantity in numbers of both bottles and candies,

Purchase quantity of candy packs shall be more than the pack of water bottles.

Further, with this option 1 and 2 are not valid as candy packs are same or less than packs of water bottle.

In option 3 and 4, option 3 have smaller quantities as provided manager bought the least possible quantity.

Accordingly

Option 3

8 packs of water bottle = 8 \times 35 = 280 \ water\ bottles

14 packs of candy = 14 \times 20 = 280 \ candies

Since the quantities of water bottles and candies are same this is an opt answer.

How many solutions does the equation -4x + 6 = 6x -2 have
SpyIntel [72]

Answer:

One.

Step-by-step explanation:

-4x + 6 = 6x - 2

-4x - 6x = -2 - 6

-10x = -8

There's only value of x which, when multiplied by -10 would produce -8.

That value is 0.8.

-10 * 0.8 = -8

No other value can produce the same result.

This means that there's only one solution.
