x=0 or x=4
just factorize basically
cancels the x’s so it’d be 3x-12=0 and from that x=4
In every triangle,if one of those three angles has his measure more than 90°,then the triangle is optuse.
If all three angles are 60°,it means the triangle equiangular.
If one of those three angles is equal to 90°,the triangle is right.
If all the angles of the triangle have their measure less than 90°,the triangle is acute.
_____________________________________________________________
Your triangle has an angle bigger than 90°,it means the triangle is optuse.
Answer:
42*7
Step-by-step explanation:
Answer:
75% of the data will reside in the range 23000 to 28400.
Step-by-step explanation :
To find the range of values :
We need to find the values that deviate from the mean. Since we want at least 75% of the data to reside between the range therefore we have,
Solving this, we would get k = 2 which shows the value one needs to find lies outside the range.
Range is given by : mean +/- (z score) × (value of a standard deviation)
⇒ Range : 25700 +/- 2 × 1350
⇒ Range : (25700 - 2700) to (25700 + 2700)
Hence, 75% of the data will reside in the range 23000 to 28400.
