When David first got a job, his annual income was $20,000. He worked hard and got more experience. After 8 years, he realized th
at his average increase in pay was about $4,000 every year. Which scatter plot represents this situation?
1 answer:
Answer:
The equation would be:
y= 4,000(x-1)+20,000
y= annual income
x= number of years
With this you can find the points for the scatter plot:
x=1 y= 20,000
x=2 y= 24,000
x=3 y= 28,000
x=4 y= 32,000
x=5 y= 36,000
x=6 y= 40,000
x=7 y= 44,000
x=8 y= 48,000
The scatter plot that represents this situation is attached.

Answer:
3.728 cm²
90
Step-by-step explanation:
To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.
Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.
So, the length of the patches is m and the width of the patches is
m.
Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)
Now, the area of the rectangular piece of material is (28 × 12) = 336 m²
Hence, ≈ 90 such patches can be made out of the whole material. (Answer)
Answer:
since p value < x(0.05) so we reject the null hypothesis
step 5 ( conclusion)
reject the null hypothesis and there is sufficient evidence to support the claim that the true average percentage differs from 5.5.
