The inequality is
The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days
Step-by-step explanation:
14 gallons-1.5 gallons=12.5 gallons
we know that
If the remaining fuel is greater than 1.5 gallons Diego's father can drive the car without the warning light coming on
so
Let
x ----> the number of days
----> inequality that represent the situation
Solve for x


The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

The sum of 32 and 5 times a number is 17​
Mrrafil [7]

"Sum of 32 and 5 times a number " translates to:

(32 + 5) × n

Then, it says "is 17"

So, (32 + 5) × n = 17. Let's solve!

32 + 5 = 37

37 × n = 17

To find n, we just divide 17 by 37. However, that equates to a repeating decimal, so it is best to put the answer as:

\frac{17}{37}

Birth weights in the United States are normally distributed with a mean of 3420 g and a standard deviation of 495 g. The Newport
s344n2d4d5 [400]

Answer:

P(2450

And we can find this probability with this difference:

P(-1.96

If we use the normal standard table or excel we got:

P(-1.96

And that represent 95% of the data. so then the percentage below 2450 is 2.5% and above 4390 is 2.5 %

Step-by-step explanation:

Let X the random variable that represent the birth weights of a population, and for this case we know the distribution for X is given by:

X \sim N(3420,495)  

Where \mu=3420 and \sigma=495

We are interested on this probability

P(2450

And we can use the z score formula given byÑ

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(2450

And we can find this probability with this difference:

P(-1.96

If we use the normal standard table or excel we got:

P(-1.96

And that represent 95% of the data. so then the percentage below 2450 is 2.5% and above 4390 is 2.5 %
