35+2x=20+2.50x
subtract 2.50x
35+0.50x=20
subtract 35 frim both sides
0.50x=-15
x=-30
Answer:
a
Step-by-step explanation:
y=mx+c, where c is the y-intercept. hence,
y=mx-6
at the x-intercept, y=0 and x = -2
0 = m(-2)-6
2m = -6
m = -3
y = -3x-6

Step-by-step explanation:
Using an hypothesis test, it is found that:
The p-value of the test is 0.177 > 0.05, which means that there is not significant evidence that the proportion of male goslings is not 50%.
----------------------------
- Test if the proportion of male goslings is different of 50%.
- At the null hypothesis, it is tested if the proportion is of 50%, that is:
- At the alternative hypothesis, if is tested if the proportion is different of 50%, that is:
----------------------------
The test statistic is given by:
In which
- p is the proportion tested.
- X is the sample proportion.
- n is the size of the sample.
----------------------------
- The proportion tested is 0.5, thus
- The sample proportion is 17 out of 27, thus .
----------------------------
The value of the test statistic is:
----------------------------
- Two-tailed test, thus the p-value of the test is P(|z| > 1.35), which is 2 multiplied by the p-value of z = -1.35.
- Looking at the z-table, z = -1.35 has a p-value of 0.0885.
- The p-value of the test is:
The p-value of the test is 0.177 > 0.05, which means that there is not significant evidence that the proportion of male goslings is not 50%.
