Answer:

Step-by-step explanation:

If the tenths slot is higher or equal to 5 then you round the whole number up.

Here it is 6 so you would round up to 6.

Answer:

Step-by-step explanation:

- First, locate the tenths digit of the number you are rounding. The tenths digit of a number is the digit directly to the right of the decimal point.

In this example, the tenths digit of 5.6 is 6.

- Next, determine whether the tenths digit is less than 5. This will determine whether how you round your number up or down. If the tenths digit is 5 or greater, you round up. If the tenths digit is less than 5 -- including 0 -- you round down.

When the tenths digit is 5 or greater, you round up. This means you add 1 to the ones digit of your number, the digit directly to the left of the decimal point.

In our example 6 is greater than 5, so you have to round up 5.6 to 6.

Solve for x. -4x - 76 < -52

Roman55 [17]

First you add 76 to get

-4x<24

And Then you divide by -4 and sincr its a negative you flip the sign to get

x>-6

Write a multiplication equation and a division equation that this diagram could represent.

vivado [14]

Answer:

$3 * 18= 54$ and $54/18 = 3$

Step-by-step explanation:

Given

$Sections = 3$

$Measurement=18$ per section

$Total\ Measurement=54$

Required

Model the scenario

The model of this scenario is:

$Sections * Measurement = Total\ Measurements$

This gives:

$3 * 18 = 54$ -- This represents the multiplication model

Divide both sides by 18

$3 * 18/18 = 54/18$

$3 * 1 = 54/18$

$3 = 54/18$

Reorder

$54/18 = 3$ -- This represents the division model

Suppose it is known that 60% of radio listeners at a particular college are smokers. A sample of 500 students from the college i

vladimir1956 [14]

Answer:

The probability that at least 280 of these students are smokers is 0.9664.

Step-by-step explanation:

Let the random variable X be defined as the number of students at a particular college who are smokers

The random variable X follows a Binomial distribution with parameters n = 500 and p = 0.60.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

1. np ≥ 10

2. n(1 - p) ≥ 10

Check the conditions as follows:

$np=500\times 0.60=300>10\\n(1-p)=500\times(1-0.60)=200>10$

Thus, a Normal approximation to binomial can be applied.

So,

$X\sim N(\mu=600, \sigma=\sqrt{120})$

Compute the probability that at least 280 of these students are smokers as follows:

Apply continuity correction:

P (X ≥ 280) = P (X > 280 + 0.50)

= P (X > 280.50)

$=P(\frac{X-\mu}{\sigma}>\frac{280-300}{\sqrt{120}}\\=P(Z>-1.83)\\=P(Z$

*Use a z-table for the probability.

Thus, the probability that at least 280 of these students are smokers is 0.9664.
