Answer:
4p² - 25
Step-by-step explanation:
given
(2p + 5)(2p - 5)
each term in the second factor is multiplied by each term in the first factor, that is
2p(2p - 5) + 5(2p - 5) ← distribute both parenthesis
= 4p² - 10p + 10p - 25 ← collect like terms
= 4p² - 25 ← in standard form
The product of the expressions (2p+5)(2p-5) in standard form, based on the difference of squares formula, is 4p² - 25.
The problem asked is to write the product in standard form for the expression (2p+5)(2p-5). Understanding this problem requires knowledge of the algebraic formula (a+b)(a-b) = a² - b² - this is known as the difference of squares.
By applying this formula to the given expression where a is 2p and b is 5, the product simplifies to (2p)² - (5)².
By squaring each of these terms individually, we get 4p² - 25. Hence, the product of the expressions (2p+5)(2p-5) in standard form is 4p² - 25.

2. TU, UV and TV are mid-segments
3. Definition of mid-segment
4. Division property of equality
6. SSS similarity theorem
Solution:
Step 1: Given
T is the midpoint of QR.
U is the midpoint of QS.
V is the midpoint of RS.
Step 2: Mid-segments connects midpoints of opposite sides.
TU, UV and TV are mid-segments.
Step 3: By definition of mid-segment
A triangle mid-segment is parallel to the third side of the triangle and is half of the length of the third side.
and
Step 4: By division property of equality
Divide first segment by RS, second segment by QR and third segment by SQ.
Step 5: By transitive property
Step 6: From the above steps, the sides of the triangle are congruent.
By SSS similarity theorem,
Hence proved.

Mean: Average number in a set of data.
STEP 1: Add up all the numbers in the set of data. In this case, we would add
66 + 85 + 98 = 249
STEP 2: Divide the sum by the number of digits you added. We would divide 249 "sum of numbers" by 3 "number of digits" and would get a quotient of 83.
-The mean for this set of data is 83-

Confidence Interval: (0.60, 0.76)
Step-by-step explanation:
The provided information is:
Sample Size (n) = 56
Consider X be the number of defective cellphones. Then X = 38
Proportion of defective cellphones is:
At 80% confidence interval, value of z is 1.28
Thus, the 80% confidence interval for proportion is given as:
