Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A = × 9 × (13 + 17)
= 0.5 × 9 × 30
= 135 cm²
Answer:
the first one is b
the second one is c
Step-by-step explanation:
have a great day :D
In stander form this would be y= 0.5x with a exponent of 2, -4x +3 so like this:
Y = 0.5x^ - 4x + 3 but the ^ = 2 as an exponent
Answer:
Option C is correct.
Step-by-step explanation:
The third one is right because the null hypothesis implies with all therapies, identical percent of kids suffer, and that simply means that there really is no distinction in drug therapies.
So, it defines the probabilities among both treated groups unless there was really no variation among drug therapies.
Due to the following reasons it describes that the following option is correct according to the statement.
Answer:
Multiply the decimal by 100, then just add the percent symbol right after.
