(₋4)²
how i got it -
1st i used the sum-product pattern
x² - 8x + 16
x² -4-4+16
then, found the common fact from the two pairs
x² - 4 - 4 + 16
(-4) - 4(-4)
rewrite in factored form
(x-4)-4(-4)
(-4) (-4)
combine to a square
(-4) (-4)
Answer:
3x=4

Answer:
Place the compass point on vertex Y and draw an arc that intersects YX and YZ
Step-by-step explanation:
Given the construction of dividing an angle inteo two equal parts.
we have to find the first step of construction.
As seen in figure the angle ∠XYZ is dividing into two equal parts.
The first step of construction is to place the needle of compass at Y and draw an arc that intersects YX and YZ.
Hence, the correct option is option C.
Place the compass point on vertex Y and draw an arc that intersects YX and YZ
Answer:
34 jerseys
8 Social Media ads
$2,400 Spent on Radio ads
$360 per TV ad
Step-by-step explanation:
2856/84 = 34 jerseys
2000/250 = 8
200*12 = 2400
1800/5 = 360
If you know how many you have and how much they cost multiply
If you know how much was spent and how much they cost divide
If you know how much was spent and how many you have divide
Answer:
The expected values for all the categories is :
And then the statistic would be given by:
And the best option would be:
b. 4
Step-by-step explanation:
For this problem we have the following observed values:
Yes 40 No 60 No Opinion 50
And we want to test the following hypothesis:
Null hypothesis: All the opinions are uniformly distributed
Alternative hypothesis: Not All the opinions are uniformly distributed
And for this case the statistic would be given by:
The expected values for all the categories is :
And then the statistic would be given by:
And the best option would be:
b. 4
