when is 9 = 15.2 - 0.537x
9 = 15.2 - 0.537x
-15.2 -15.2 subtract 15.2 from both sides
-6.2 = -0.537x
/-0.537 /-0.537 divide -0.537 from both sides
11.55 = x or 12 feet round to nearest whole foot
The x values range from -6 to 6, *including* those two numbers, so the domain is [-6, 6], and the y values range from -2 to 2, also inclusively, so the range is [-2, 2]
Let P be the population proportion, p be the sample proportion, n be the sample size.
A manufacturer claims that fewer than 6% of its fax machines are defective. It means P=0.06
Sample size n=97 and sample proportion p=0.05
The hypothesis to be tested is
H0: P ≥ 0.06 V/s Ha: P < 0.06
Here the hypothesis for testing population proportion we use z test statistics. Z test statistics is give by
Z = 
Where p =sample proportion = 0.05
p0 = hypothesized proportion value =0.06
Using given values into test statistics we get
Z = 
Z = -0.41
The p-value for left tailed alternative hypothesis is given by
P-value = P(z < z cal)
where zcal = Z test statistics value
Here zcal = -0.41
P-value = P(Z < -0.41)
Using z score table to find probability below z=-0.41
P-value = 0.3409
P-value for testing the given claim is 0.3409

Answer:
- slope: -2/3
- y-intercept: -1
Step-by-step explanation:
The line crosses the y-axis 1 unit below the x-axis. That makes the y-intercept be -1.
The line crosses through another grid intersection 3 units to the right and 2 units down from the y-intercept. That is, the slope is ...
m = rise/run = -2/3
The slope is -2/3; the y-intercept is -1.
