Answer:
B) obtuse triangle
Step-by-step explanation:
2(p+1)=16
2p+2=16
2p= 16-2
2p= 14
p= 14 ÷2
p= 7
To find 33% of 1.45 we have to transform 33% into decimal or fraction
33% is 0.33 or and multiply if by 1.45
so
0.33*1.45=0.4785
Answer:
458
Step-by-step explanation:
Margin of error = critical value × standard error
At 99% confidence, the critical value is z = 2.576.
The standard error is σ/√n = 5.4/√n.
Given the desired margin of error is 0.65:
0.65 = 2.576 × 5.4/√n
n = 458
Convert to Y=MX+B to make it easier, minus 2x from both sides to get -7y=-2x+14, then divide it all by -7 to get y=2/7x-2. 2 equals your starting point, from there go down 2 and over 7 for you slope and repeat until the graph is done.
