Answer:
D
Step-by-step explanation:
p +/- [z + sqrt(pq/n)]
0.65 + [1.645 × sqrt[0.65 × (1-0.65) ÷ 50]
0.65 +/- 0 1109613165
[0.5390386835 , 0.7609613165]
Billy want to re-do his bathroom tiles. He finds out the length and width. Then he uses estimation to figure out how many tiles he needs to buy.
Answer:
120.8°
Step-by-step explanation:
the total angle sum is of 360 so we add and subtract
35.8+25.4+178= 239.2
360-239.2= 120.8
so the missing angle measure is 120.8°
Solve the inequality for x:
5x - 3 ≤ 7x +7
Subtract 7x from each side:
-2x -3 ≤ 7
Add 3 to each side:
-2x ≤ 10
Divide both sides by -2, also when dividing both sides of an inequality you flip the direction of the inequality sign:
x ≥ -5
The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.
The correct answer is D.
