<span>Based on this sample, and assuming the word "widget" means removed, the answer is four. They only tested 50 bottles and found four (one under, three over). The question also contains the word "Jack's, " the meaning is unclear. The factory shipped 1000 bottles of Hosta sauce, assuming the same ratio as the random sample (0.0008%) then the factory shipped 80 bottles that are incorrect.</span>

The data points represebt the number of swimmers at City Pool compared to the outside temperature (66, 8) (71, 23) (72 16) (75 3
PIT_PIT [208]

Answer:

44 swimmers

Step-by-step explanation:

Given the data points :

66, 8) (71, 23) (72 16) (75 30) (78 35) (80 24) (82 37) (86 37) (87 42) (90 50)

Temperature X:

90

Number of swimmers Y:

8

23

16

30

37

42

50

Using the online regression calculator :

The regression model obtained is ;

ŷ = 1.5045X - 88.2056

Where

1.5045 = gradient or slope

-88.2056 = intercept

x = independent variable

y = dependent variable

Number of swimmers when temperature = 88

y = 1.5045(88) - 88.2056

y = 44.19

y = 44 (nearest whole number)

Given the equation 8x + 4y = 2, a second equation that forms a system with no solution is:
Murrr4er [49]

Answer:

4x + 2y = 2

Step-by-step explanation:

8x + 4y = 2 ( divide each term by 2 )

4x + 2y = 1 → (1)

we require a situation where the left side cannot possibly equal the right side.

using 4x + 2y = 2 → (2)

subtract (1) from (2) term by term

(4x - 4x) + (2y - 2y) = 2 - 1 , that is

0 + 0 = 1

0 = 1 ← not possible

thus the system has no solution

Kumar has twice the number of goals as Jacob. Make an algebraic expression. Plzzzz help
alekssr [168]

The algebraic expression is x = 2y where, "x" is the number of goals with Kumar and "y" is the number of goals with Jacob

<em><u>Solution:</u></em>

Given that Kumar has twice the number of goals as Jacob

To find: algebraic expression

An algebraic expression is a mathematical expression that consists of variables, numbers and operations

<em><u>Let us first define the variables</u></em>

Let "x" be the number of goals with Kumar

Let "y" be the number of goals with Jacob

Then from given statement,

Number of goals with kumar = twice the number of goals as Jacob

Number of goals with kumar = 2(number of goals with Jacob)

x = 2y

Thus the algebraic expression is found
