Can someone help me with mine :(
Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
I know my sibling wil answer it

Answer:
The z-scores are and
Step-by-step explanation:
From the question we are told that
The middle of the distribution area considered is 48%
Now the rest of the area under the standard normal distribution area is mathematically evaluated
Now to obtain the area occupied by this proportion at the two tails we divide by 2 i.e
Now the z-score is obtained from the normal distribution table and the value is
The shows that we are considering the two-talil
