Answer:

triangle given is not a right triangle

Step-by-step explanation:

Given:-

- The side lengths of a triangle are given as:

                                     24 , 32 , 42

Find:-

is it a right triangle? explain

Solution:-

- Any triangle which conforms to the pythagorean theorem can be classified as a right angle triangle.

- The Pythagorean theorem states that the square of the longest side length known as hypotenuse (H) should be equal to the sum of square of other two side lengths ( Perpendicular / opposite [ P ] and Base / Adjacent [ B] ).

- This can be mathematically expressed as:

                                     H^2 = P^2 + B^2

- From the given side lengths. The largest side length is hypotenuse H = 42. While P and B can be used interchangeably for the other two side lengths. So using the theorem we have:

                                     42^2 = 32^2 + 24^2

                                     1764 : 1024 + 576

                                    1764 ≠ 1600

- We see that the three side lengths of the triangle does not conform to theorem. So we can conclude that the triangle given is not a right triangle.

When given 3 triangle sides, to determine if the triangle is acute right or obtuse
square all 3 sides
sum the squares of the 2 shortest sides
compare this sum to the square of the 3rd side
if sum > 3rd side squared it's an acute triangle
if sum = 3rd side squared it's a right triangle
if sum < 3rd side squared it's an obtuse triangle

24 32 42

24*24 = 576
32*32 = 1,024
42*42 = 1,764

Sum of the square of 2 shortest sides = 1,600

Since 1,600 < 1,764 these sides form an obtuse triangle.

Answer:

p-value: 1.000

There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.

Step-by-step explanation:

We will be conducting a difference of 2 proportions hypothesis test

The hypothesis for this test is:

H_0:  p1 - p2=0

H_a:  p1 - p2  ≠0

(p1 ) = 252/300 = 0.84

(p2) = 195/300 = 0.65

This is a 2 tailed test with a significance level of 1%.  So our critical values are:  z > 2.575  and z < -2.575

See the attached photo for the calculations for this test

What is the measure of
harina [27]

Answer:

<DAB   = 120

Step-by-step explanation:

7)

<DAB = ?

<DAB + <DCB = 180

so

16x + 8 + 8x + 4 = 180

24x + 12 = 180

24x = 168

x = 7

<DAB  = 16(7) + 8 = 120

An object is dropped off a building that us 144 feet tall. After how many seconds does the object hit the ground? (s= 16t^2)
denis23 [38]
Given 
s=16t^2 
where
s=distance in feet travelled (downwards) since airborne with zero vertical velocity and zero air-resistance
t=time in seconds after release

Here we're given
s=144 feet
=>
s=144=16t^2 
=> 
t^2=144/16=9
so
t=3
Ans. after 3 seconds, the object hits the ground 144 ft. below.

What is 12 2/3 as an improper fraction
BaLLatris [955]

Answer:

\dfrac{38}{3}

Step-by-step explanation:

12\dfrac{2}{3} =

= 12 + \dfrac{2}{3}

= \dfrac{12}{1} + \dfrac{2}{3}

= \dfrac{12}{1} \times \dfrac{3}{3} + \dfrac{2}{3}

= \dfrac{36}{3} + \dfrac{2}{3}

= \dfrac{38}{3}
