Find the value of x.

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:

66

71

72

75

78

80

82

86

87

90

Number of swimmers Y:

8

23

16

30

35

24

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)

Answer:

Step-by-step explanation:

We know: the sum of the measures of triangle angles is 180°.

Therefore we have the equation:

$2x+(3x-10)+50=180\\\\(2x+3x)+(-10+50)=180\\\\5x+40=180\qquad\text{subtract 40 from both sides}\\\\5x+40-40=180-40\\\\5x=140\qquad\text{divide both sides by 5}\\\\\dfrac{5x}{5}=\dfrac{140}{5}\\\\x=28$

Rainbow [258]

Answer:

The fraction of the students play soccer = $\frac{2}{5}$

Step-by-step explanation:

Given - In the town of Destin, 2/3 of the students in middle school participate in organized sports after school.

To find - If 3/5 of them play soccer, what fraction of the students play soccer? Enter your answer in simplest form

Solution -

Let us assume that,

Total number of students in the middle school = 3x

Now,

Given that

2/3 of the students in middle school participate in organized sports after school.

So,

Total students participated in organized sports = (2/3)×3x

= 2x

⇒Total students participated in organized sports = 2x

Now,

Given that,

3/5 of them play soccer

So,

Total players who play soccer = (3/5)×2x

= 6x/5

⇒Total players who play soccer = 6x/5

Now,

The fraction of total students play soccer = (6x/5) ÷ (3x)

= $\frac{6x}{5}*\frac{1}{3x}$

= $\frac{2}{5}$

∴ we get

The fraction of the students play soccer = $\frac{2}{5}$
