According to U.S. climate data, the monthly average high temperatures, in degrees Fahrenheit, for the city of Chicago are listed

sergejj [24]

Answer: (C) Sample minimum: 32, Sample maximum: 81 Q1:39.5, Median: 58, Q3: 74

Step-by-step explanation:

Five number summary for a data contains :

Minimum value

First quartile $(Q_1)$

Median

Third quartile $(Q_3)$

Maximum value.

Given data : 32, 34, 43, 55, 65, 75, 81, 79, 73, 61,47, 36

Arrange in order →32, 34, 36, 43,47, 55, 61, 65, 73, 75, 79, 81

Total values = 12 (even)

⇒ Median = Mean of the middle most two values.

$=\dfrac{55+61}{2} =58$

First quartile = Median of first half (32, 34, 36, 43,47, 55)

$Q_1=\dfrac{36+43}{2}=39.5$

Third quartile = Median of first half (61, 65, 73, 75, 79, 81)

$Q_3=\dfrac{73+75}{2}=74$

Also, Sample Minimum value = 32

Sample Maximum value=81

Therefore , the five-number summary for this data :

Sample Minimum=32

Sample Maximum=81

Median = 58

$Q_1=39.5$

$Q_3=74$

Hence, the correct option is (C) Sample minimum: 32, Sample maximum: 81 Q1:39.5, Median: 58, Q3: 74

Find the missing angles

SashulF [63]

$\huge\bold{Given :}$

Angle a = 39°

Angle c = 123°

$\huge\bold{To\:find :}$

The measure of angle b.

$\large\mathfrak{{\pmb{\underline{\orange{Solution}}{\orange{:}}}}}$

∠ b = 18°

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}$

We know that,

$\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}$

➪ ∠ a + ∠ b + ∠ c = 180°

➪ 39° + ∠ b + 123° = 180°

➪ ∠ b + 162° = 180°

➪ ∠ b = 180° - 162°

➪ ∠ b = 18°

Therefore, the measure of ∠ b is 18°.

$\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}$

∠ a + ∠ b + ∠ c = 180°

✒ 39° + 18° + 123° = 180°

✒ 180° = 180°

✒ L. H. S. = R. H. S.

$\boxed{Hence\:verified.}$
