In 7500 iPhones, 18 were found defective.
18 of 7500 is 0.24%
0.24% of iPhones were defective.
Using the information above:
In a sample of 60000 new iPhones, 144 would be found defective.
144 of 60000 is 0.24%
Answer: 144 defective iPhones would be expected in a sample of 60,000.
Hope this helps! Good luck. :-)
The answer has to be in y-intercept form. Which is y=mx+b and b can also be neg. y=mx-b. The m is your slope and b is your y-intercept. So A’s slope counting from 3 on the y axis to 1 on the x-axis which is down 2 over 1 so it will be -2/1. And your y intercept is 3. The equation is y=-2x+3. For B its the same thing but no graph. Remember that slope is RISE over RUN. So since the number is on the bottom of the line the rise is 4 and the run is 1. So in this case 10 is your y-intercept. Which means you equation is y=4x+10.
Answer:
Step-by-step explanation:
It should be diagonal not diameter.
The diagonal of the square is √2 time the side.
The side given 1 unit, then the diagonal is x = √2 units
Answer:
A. (2, -3).
Step-by-step explanation:
The first step is to complete the square on the terms in x and the terms in y:
x² - 4x +4 +y² +6y + 9 =4
= (x - 2)² - 4 + (y + 3)² - 9 + 4 + 9 = 4
= = (x - 2)² + (y + 3)² - 9 + 9 - 4 + 4 = 4
= (x - 2)² - (y + 3)² = 4.
So the centre is at (2, -3).
Answer:
The answer would be that this graph is NOT a proportional relationship.
La respuesta sería que este gráfico NO es una relación proporcional.
Step-by-step explanation:
The reason why this graph makes no relationship is because a relationship needs to be constantly equivalent to the past fraction. But would 2 be equal to 5 and 4 be equal to 10? Nope, that is why it is not a proportional relationship.
La razón por la cual este gráfico no tiene relación es porque una relación debe ser constantemente equivalente a la fracción pasada. ¿Pero sería 2 igual a 5 y 4 igual a 10? No, por eso no es una relación proporcional.
