Answer:
231.5in squared
Step-by-step explanation:
Both faces area formula
Rectangle: l x w
triangle: b x h / 2
Answer:
See explanation below.
Step-by-step explanation:
The equation is:
y = 7x + 6
This is the equation of a line in slope intercept form. The general form, where m is the slope and b is the y intercept is:
y = mx + b
In this case, with the equation:
y = 7x + 6
m is 7 and the y intercept is 6.
The y intercept means the point when x = 0:
(0, 6) is the y intercept point on the graph.

Answer:
No
Step-by-step explanation:
To see if (2,2) is a solution, substitute them into the inequality and see if it is true.
2 is our x value, and 2 is also our y value
y < 4x – 6
2< 4(2)– 6
2 < 8 – 6
2 < 2
This statement is false. 2 is not less than 2, so (2,2) is not a solution to this equation.
Answer:
The plane flew for 3 hours at 105mph and 115mph for 5 hours

Answer:
Check Explanation
Step-by-step explanation:
a) Confidence Interval for the population mean is basically an interval of range of values where the true population mean can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample mean) ± (Margin of error)
With p(japan) representing the true population proportion of US automobile that are made in Japan, the computer output 90% confidence
0.29938661 < p(japan) < 0.46984416
mean that p(japan); the true population proportion of US automobile that are made in Japan lies within the range of proportions (0.29938661, 0.46984416) with an assurance level of 90%.
b) 90% confidence mean that the true proportion may or may not be in the given range, but we are 90% certain that it does.
c) The confidence interval contradicts the politician's claim that "Half of all cars in the United States are made in Japan" because the proportion in the politician's claim, (0.50), does not lie within the range of values that our confidence interval says the true population proportion can take on; (0.29938661, 0.46984416).
0.50 lies outside of the confidence interval obtained for the true population proportion of US automobiles that are made in Japan, hence, the confidence interval contradicts the politician's claim.
Hope this Helps!!!
