Answer:
Step-by-step explanation:
1). 8(5)-8+10
40-8+10
32+10
42, so answer is C
2). 9/5(42)+32
9(8.4)+32
75.6+32
107.6°F, so answer is D
Its also 40°30' because the median is also a bisector in isosceles triangle
"mono" means 1 or single. In algebra, a monomial is any number that is alone or by itself. For this question, among the choices, the monomial is the number 4. Therefore the answer to this question is letter B. 4.
The answer is 10 because when you use the slope formula y^2 - y^1 divided by x^2 - x^1 and plug your points in you get 10/0 which makes the answer ten
Answer:
The minimum guaranteed mileage is ![x = 71489.55](https://tex.z-dn.net/?f=x%20%3D%2071489.55)
Step-by-step explanation:
From the question we are told that
The mean is ![\mu = 67900](https://tex.z-dn.net/?f=%5Cmu%20%20%3D%20%2067900)
The standard deviation is ![\sigma = 2050](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%202050)
Generally for the probability to be 4% the minimum guaranteed mileage is evaluated as
![P( X \ge x ) =1- P( \frac{X - \mu }{\sigma } < \frac{ x - 67900 }{ 2050} ) = 0.04](https://tex.z-dn.net/?f=P%28%20X%20%20%5Cge%20x%20%29%20%3D1-%20%20P%28%20%5Cfrac%7BX%20-%20%5Cmu%20%7D%7B%5Csigma%20%7D%20%3C%20%5Cfrac%7B%20x%20-%20%2067900%20%7D%7B%202050%7D%20%20%29%20%3D%200.04)
![\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )](https://tex.z-dn.net/?f=%5Cfrac%7BX%20-%5Cmu%7D%7B%5Csigma%20%7D%20%20%3D%20%20Z%20%28The%20%20%5C%20standardized%20%5C%20%20value%5C%20%20of%20%20%5C%20X%20%29)
![P( X \ge x ) =1- P( Z](https://tex.z-dn.net/?f=P%28%20X%20%20%5Cge%20x%20%29%20%3D1-%20%20P%28%20Z%3Cz%29%20%3D%200.04)
=> ![P( X \ge x ) = P( Z](https://tex.z-dn.net/?f=P%28%20X%20%20%5Cge%20x%20%29%20%3D%20P%28%20Z%3Cz%29%20%3D%200.96)
=> ![z = \frac{ x - 67900 }{ 2050}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B%20x%20-%20%2067900%20%7D%7B%202050%7D)
From the z table, the critical value corresponding to 0.96 to the left of the curve is
![z = 1.751](https://tex.z-dn.net/?f=z%20%3D%201.751)
So
![1.751 = \frac{ x - 67900 }{ 2050}](https://tex.z-dn.net/?f=1.751%20%3D%20%5Cfrac%7B%20x%20-%20%2067900%20%7D%7B%202050%7D)
=> ![x = 71489.55](https://tex.z-dn.net/?f=x%20%3D%2071489.55)
