Answer:
first calculate the area of the rectangle which is given by L×W
take thw length of the rectangle and substract the b of the trapezium which 4.5 you find y divide it by 2 since they're two. the answer you'll get is the height of both shaded triangles . take the base of the shaded triangles and the height y then find the area. the answer you'll get multiply it by 2.
Step-by-step explanation:
11×7=77
11-4.5=6.5
6.5/2
(½×7×6.5/2)2
=22.75m²
An arithmetic sequence is one where each term is a constant difference, called the common difference, from the preceding term. The arithmetic sequence can always be expressed as:
a(n)=a+d(n-1), a=first term, d=common difference, n=term number.
We are given two terms and term numbers, so we can solve for the common difference...
101=5+d(25-1)
101=5+25d-d
101=5+24d
96=24d
d=4
So the common difference is 4.

Notice how when it rhymes, you connect the number to what it rhymes with. You continue the numbers or letters until a rhyme then look at what it rhymes with and match it.
Hope this helps have a great day :D
Answer:
c. the variance of the difference scores is near zero
Step-by-step explanation:
If all the participants show improved performance of 8 or 9 points after treatment, what should the researcher find - the variance of the difference scores is near zero.
But this can be true only when the original scores had a low variance.
(x/7)-12=-2
Add 12 to both sides.
x/7=10
Multiply both sides by 7.
x=70
Final answer: 70
hope this helps :)
