Mathematics
1 answer:
Nady [450]3 years ago
5 0

Answer:

a) 46° b) 66° c) 4 cm

Step-by-step explanation:

a) because it is isosceles triangle, therefore, 2 opposite angles, and angle sum of triangle is 180 so 180-67-67=46

b) because again, isosceles triangle so two opposite sides,

x+x+48=180

2x=132

x=66

c)because it is equilateral, so therefore all angles are 60 degrees and all sides equal.

Solve for x 6 ( x − 2 ) = 8 ( x − 9 )
valentinak56 [21]

Answer:

x = 30

Step-by-step explanation:

in order to solve for the value of x in the expression 6 ( x − 2 ) = 8 ( x − 9 )

we will first of all open the brackets and then evaluate for the value of x by combining the like terms.

from 6 ( x − 2 ) = 8 ( x − 9 )

6x -12 = 8x -72

combine the like terms

6x - 12 + 72 = 8x

-12 + 72 = 8x -6x

60 = 2x

divide both sides by the coefficient of x which is 2

60/2 = 2x/2

30 = x

x = 30

therefore the value of x in the expression 6 ( x − 2 ) = 8 ( x − 9 ) is equals to 30

Amir stands on a balcony and throws a ball to his dog, who is at ground level. The ball's height (in meters above the ground), x
Y_Kistochka [10]
When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0=-(x-2)^{2}+16 \\  \\ 
(x-2)^{2}=16 \\  \\ 
x-2= \sqrt{16} \\  \\ 
x-2=4 \\  \\ 
x=6

This means the ball will hit the ground 6 seconds after Amir threw it

The following graphs show the sampling distributions for two different point estimators, R and W, of the same population paramet
Sidana [21]

The graphs are illustrations of biased and unbiased distributions.

The true statement is (d) R is biased, and W is unbiased

<h3>How to determine which of the graph is biased</h3>

From the graph, we have the following highlight

  • The population parameter of graph R is at the right of the distribution
  • The population parameter of graph W is at the center of the distribution

The above means that:

Graph R is biased, and graph W is unbiased
