What is the probability that a randomly selected dunlop tire lasts between 65000 and 80000 miles?

You are looking at around 81.5% i assume by shifting the standard deviation by the same amount on both sides the % will not change
i split the normal distribution curve into 8 pieces
.15 +2.35+13.5+34+34+13.5+2.35+.15 34+34+13.5=81.5%
the ones bolded are the sections that u r dealing with
now the standard deviation is only 4400 so these numbers are going to be skewed off to the right a bit however bcus both sides are skewed evenly i believe they balance each other out
im not completely certain of this but still i hope i helped if so give me a brainliest answer i need a few more to move up a rank -J (:

Use the five-step plan to solve the following problem. Joey has nickels and dimes in his pocket. The number of dimes is 3 times

HACTEHA [7]

Not sure what the 5 step plan is but

Joey has 11 nickels
so from "The number of dimes is 3 times the number of nickels."
we know joey has 33 dimes.
11 nickels is 55 cents. 33 dimes is 3 dollars and 30 cents
in total 3 dollars and 85 cents

У — 3x 4 у > 4х +1 Anyone know the answe on how to solve this???

Katen [24]

Answer:

Unbounded, infinite number of solutions

Step-by-step explanation:

1. Graph each inequality separately

2. Choose test point to determine which side of line needs to be shaded

3. The solution will be the the area where the shadings from both inequalities overlap

Since, the overlap almost covers the 2nd and 3rd quadrants there are an infintite number of solutions

Un alumno multiplica un número por 32 en lugar de multiplicarlo por 23, obteniendo un producto mayor en 54 al producto original.

romanna [79]

Answer:

La suma de cifras del producto original es igual a 12.

Step-by-step explanation:

De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:

32x=y+54

Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:

y=23x

Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:

32x=23x+54

32x-23x=54

9x=54

x=54/9

x=6

Finalmente, puedes reemplazar el valor de x en y=23x:

y=23x

y=23*6

y=138

Suma de cifras: 1+3+8 = 12

De acuerdo a esto, la respuesta es que la suma de cifras es igual a 12.

Hey there!

Assuming that $"f" = y$

So, let's solve your function, shall we?

$y(-1) = 2 \\ \\ \\ -y= 2 \\ \\ DivideBy(-1) \\ \\ \\ \frac{-y}{1} = \frac{2}{-1} \\ \\ \\ CancelOut: \frac{-y}{1} \\ \\ \\ Keep: \frac{2}{-1} \\ \\ \\ \\ Answer: y = -2 (option D)$

Good luck on your assignment and enjoy your day!
