Answer:
y=|x|-7
Step-by-step explanation:
When looking at an equation like so the number will stay the same but what changes is the adding or subtracting symbol.
+ = Up(Positive)
- = Down(Negative
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
Rectangle = 9*5=45
Triangle= 1/2 * 10 * 3 = 15
Add the two shapes: 45+15 = 60 sq units
-6*3 =-18
11*4=44
-18/44. Reduce. Divide top and bottom by 2
-9/22
1) around 1300
2) around 30
3) a. about 500
b. about 2600
Hope this helps you!
