Answer:

35°, 15, 130°

70°, 70°, 70°

90°, 3 inches, 7 inches

Step-by-step explanation:

35°, 15, 130° = 185° Could be an Obtuse triangle and a triangle = 180°

70°, 70°, 70° = Equalateral Triangle

90°, 3 inches, 7 inches = Right Triangle because it has one angle that measures 90°

Hopes this helps let me know if not correct

Answer:

a) X = 2/15 , 8/15, 1/3

b) attached below ( probability plot )

C) F(x ) attached below

d) cumulative probability plot

Step-by-step explanation:

a) Determine the probability of Function X

P( x = 0 ) = 6 / 45 = 2 /15 = 0.1333

P( x = 1 ) = 8/15 = 0.5333

P( x = 2 ) = 1/3 = 0.3333

Hence the probability of Function X = 2/15 , 8/15, 1/3

b) Graph of the probability Function of X

x 0 1 2

p(x) 0.1333 0.5333 0.3333

attached below is the plot ( probability plot )

<u>c) Determine the Distribution function of CX </u>

EXPERT HELP: DON'T GUESS EXPLAIN THE ANSWER OR YOU WILL BE REPORTED

sveticcg [70]

Answer:

The correct answer is A.

Step-by-step explanation:

Given that a weather researcher compared Dublin, Ireland to Madrid, Spain, and she found that Dublin had a mean average temperature of 56.1ºF with a mean average deviation of 6.4ºF, while Madrid had a mean average temperature of 68ºF with a mean average deviation of 12.1ºF, the following conclusions can be drawn:

68 is higher than 56.1, so clearly Madrid has a higher average temperature than Dublin.

In turn, 12.1 is greater than 6.4, with which Madrid has a greater temperature variation than Dublin.

Mr. Reed is drawing a blueprint of a rectangular patio. The width of the patio is 40 3/4 feet shorter than twice its length. The

Damm [24]

Answer:

Length of rectangular patio = 28 feet

Step-by-step explanation:

Given that:

Length of rectangular patio = x

Width of rectangular patio = $2x-40\frac{3}{4}$

Perimeter of rectangular patio = $86\frac{1}{2}$

Perimeter of rectangular patio = 2 (length + width )

Putting values in the formula

$86\frac{1}{2}=2(x+2x-40\frac{3}{4})\\\\\frac{173}{2}=2(3x-\frac{163}{4})\\\\\frac{173}{2}=2(\frac{12x-163}{4})\\\\\frac{173}{2}=\frac{12x-163}{2}\\\\173 = 12x-163\\12x = 173 + 163 \\12x = 336$

Dividing both sides by 12

$\frac{12x}{12}=\frac{336}{12}\\x=28$

Hence,

Length of rectangular patio = 28 feet

A function P(x) has both 2 and 3 as roots, x=5 is a solution such that P(5)=0, and the degree of P(x) is 2. Explain why no such

antiseptic1488 [7]

Answer:

Step-by-step explanation:

Roots mean the the function has a result of zero at that point. This function would therefore have zeros at 2, 3 and 5 and the degree would be at LEAST 3 and possibly higher depending on the multiplicity of each root.

factors would be

(x - 2)ⁿ¹(x - 3)ⁿ²(x - 5)ⁿ³ where n₁, n₂ and n₃ are Whole numbers ≥ 1
