mrs_skeptik [129]

Answer: 3424.28

Step-by-step explanation:

Given data : 378, 361, 350, 375, 200, 391, 375, 368,  321

Number of data values = 9

Mean :\overline{x}=\dfrac{\sum^n_{i=1} x_i}{n}

\\\\=\dfrac{378+361+350+375+200+391+375+368+321}{9}\\\\=\dfrac{3119}{9}\approx346.56

Variance = \dfrac{\sum^n_{i=1} (x_i-\overline{x})^2}{n-1}

\sum^n_{i=1} (x_i-\overline{x})^2 = (31.44)^2+(14.44)^2+(3.44)^2+(28.44)^2+(-146.56)^2+(44.44)^2+(28.44)^2+(21.44)^2+(-25.56)^2\\\\=27394.2224

Variance = \dfrac{27394.2224}{8}=3424.2775\approx3424.28

What's the value of x and y?​
krok68 [10]

Answer:

x = 45 and y = 90

Step-by-step explanation:

Let the third angle be z

z = 180 - 135 (Linear Pair)

z = 45

Since its an iscosceles triangle,

<z = <x (angles opposite to equal sides have equal angles)

<x = 45 degree

<z + <x + <y = 180

45 + 45+ <y = 180

90 + <y = 180

<y = 180 - 90

<y = 90

Therefore x = 45 and y = 90

Hope u understood please mark as brainliest

Thank You

Which answer choice is a solution to the inequality 1.5x + 3.75≥5.5
djyliett [7]

Answer:

x \geq \frac{7}{6}

The value of x is greater than or equal to 7/6

Step-by-step explanation:

1.5x + 3.75\geq 5.5

Solve the inequality for x

Subtract 3.75 from both sides

1.5x + 3.75\geq 5.5

1.5x \geq 1.75

Now divide both sides by 1.5

x \geq \frac{1.75}{1.5}

Simplify the fraction by dividing top and bottom by 0.25

x \geq \frac{7}{6}

The value of x is greater than or equal to 7/6
