Answer:
They are SIMILAR triangles
Step-by-step explanation:
Given triangles MNL and FHG with two of their angles to be 51° and 36° respectively. Their third angle is expressed as:
180°-(51°+36°)
= 180°-87°
= 93°
Their third angle is 93°
Since both triangles have the same angles in them, both triangles are considered as similar triangle even though the value of their sides are different due to angle differences in both.
Note that individual triangles are scalene triangles since their angles are not the same but the both triangles are similar triangles based on their relationship.
The area is 60m squared.
The formula for a triangle is base times height, divided by 2. Base times height in this case is 10m x 12m, which is 120m. 120m divided by 2 is 60m squared. (It is squared because it is not just a length, but an area of a flat shape.)
1,3,4 are true and 2 is false
Answer:
Hi how are doing?
Step-by-step explanation:
Answer:
Step-by-step explanation:
sample size ( n ) = 2500 women ( computer and mathematical occupations )
Average earnings of sample ( X )= $75000 / year
standard deviation ( s )= $9500
a) knowing that the average earnings of men are $89,000/year, the null and the alternative hypotheses that the average earnings of women match the average earnings of men in the population.
Given ; Ц = $89000
Null hypothesis ( H0) : Ц = $89000
Alternative hypothesis ( H1 ) : Ц ≠ $89000
The test is : one sample t test hypothesis
b) Test statistic
Test statistic ( t ) =
