Answer:
x = 5
Step-by-step explanation:
Start by distributing the 5 to remove parentheses. To do this multiply the numbers and variable in the parentheses by 5.
10x - 20 - 11 = 4 + 3x
Next. you want to get the variables to one side. This is done by subtracting 3x from both sides.
7x - 20 - 11 = 4
Now solve the -20 - 11.
7x - 31 = 4
You need to have the variable all by itself. To do this, first add -31 to both sides.
7x = 35
Finally divide by 7.
x = 5
Hope this helped.
Answer:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in

Answer:
0.6848
Step-by-step explanation:
Mean of \hat{p} = 0.453
Answer = 0.453
Standard deviation of \hat{p} :
= \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = \sqrt{\frac{0.453(1-0.453)}{100}} = 0.0498
Answer = 0.0498
P(0.0453 - 0.05 < p < 0.0453 + 0.05)
On standardising,
= P(\frac{0.0453-0.05-0.0453}{0.0498} <Z<\frac{0.0453+0.05-0.0453}{0.0498})
= P(-1.0044 < Z < 1.0044) = 0.6848
Answer = 0.6848
