Answer:
Step-by-step explanation:
The Pythagorean theorem tells you that the area of the square with side 'a' is the difference of the areas of the other two squares.
a² = 7² -4²
a² = 49 -16 = 33
a = √33
Answer:
49
Step-by-step explanation:
Answer:
<u>4 minutes</u>
Step-by-step explanation:
40=1 min
40=2 min
40=3 min
40=<u>4</u> min
40x4 or 40+40+40+40 is <u>160</u>
The number of throws that the player make X follows binomial distribution.
The probability that the player makes x throws out of eleven throws is
The probability that the player makes at most nine out of eleven free throws
is
Correct choice is (B).
Answer:
x = 29
Step-by-step explanation:
If the equation is :
4.2(9-x)+36=102-2.5(2x+2)
→distribute 4.2 and -2.5 in parenthesis
4.2(9 - x) + 36 = 102 -2.5(2x + 2)
37.8 - 4.2x +36 = 102 -5x -5
→ have terms with x = terms without x
Keep the terms you need the way they are, and move the terms you need on the other side of equal sign with changed sign.
4.2(9 - x) + 36 = 102 -2.5(2x + 2)
37.8 - 4.2x +36 = 102 -5x -5
- 4.2x +5 x = - 37.8 - 36 + 102 - 5
→ Combine like terms
0.8x = 23.2
→ Divide both sides by 0.8
x = 29
