Answer:

The answer is the option $x+49\°+28\°=180\°$

Step-by-step explanation:

see the attached figure with letters to better understand the problem

we know that

$m$

$m$ -----> by vertical angles

$m$ -----> given problem

substitute

$28\°+x+49\°=180\°$

HELP ASPAP!!!!! WILL MARK BRAINIEST standard deviation

Umnica [9.8K]

Answer:

The standard deviation of the given data is 11.34.

Step-by-step explanation:

We have to find the standard deviation for the given data;

Grade on No. of students

test (X) with that score (f) $X \times f$ $( X - \bar X)^{2}$ $f \times ( X - \bar X)^{2}$

50 1 50 1073.218 1073.2176

57 2 114 663.578 1327.1552

60 4 240 518.018 2072.0704

65 3 195 315.418 946.2528

72 3 216 115.778 347.3328

75 12 900 60.218 722.6112

77 10 770 33.178 331.776

81 6 486 3.098 18.5856

83 6 498 0.058 0.3456

88 9 792 27.458 247.1184

90 12 1080 52.418 629.0112

92 12 1104 85.378 1024.5312

95 2 190 149.818 299.6352

99 4 396 263.738 1054.9504

100 5 500 297.218 1486.088

Total 91 7531 11580.68

Firstly, the mean of the above data is given by;

Mean, $\bar X$ = $\frac{\sum X \times f}{\sum f}$

= $\frac{7531}{91}$ = 82.76

Now, the standard deviation of the data is given by;

Standard deviation, S.D. = $\sqrt{\frac{\sum f(X-\bar X)^{2} }{\sum f-1}}$

= $\sqrt{\frac{11580.68}{91-1}}$

= 11.34

Hence, the standard deviation of the given data is 11.34.

Please help with math

Sergio [31]

Answer: x = 2

Step-by-step explanation:

$x+y=8\\y=3x$

Replace y in the first equation by the value of y in the second equation.

$x+y=8\\x+3x=8\\4x=8\\x=\frac{8}{4}\\ x=2$

Which expression is equivalent to xy^2/9?

Law Incorporation [45]

Answer:

$xy^\frac{2}{9} = x*\sqrt[9]{y^2}$

Step-by-step explanation:

Given

$xy^\frac{2}{9}$

Required

The equivalent expression (see attachment)

We have:

$xy^\frac{2}{9}$

Split

$xy^\frac{2}{9} = x*y^\frac{2}{9}$

Apply the following laws of indices

$y^\frac{m}{n} = \sqrt[n]{y^m}$

So, we have:

$xy^\frac{2}{9} = x*\sqrt[9]{y^2}$

Hence (d) is correct
