Answer:

503.8

Step-by-step explanation:

You need to find the tenths digit which would be the 7. The number after is 8, which rounds up, making the 7 an 8

5 0

Answer:

503.8

Step-by-step explanation:

Since the tenth is the first number after the decimal point, we only need the first and second numbers after the decimal point. Plus, the 2 would do nothing to help us anyway.

Rule: in order to round up the number needs to be 5 or higher

That is the rule we will be using because 8 is 5 or higher.

When you round 7 up by 1, it equals 8 making the answer:

503.8

The average price of an item is $42 with a standard deviation of $3

FinnZ [79.3K]

The mean price goes between $ 41.16 and $ 42.84, so a value of $ 48 is unusually high.

Since the average price of an item is $ 42 with a standard deviation of $ 3, to find a 98% confidence interval about the mean, and determine if a value of X = 48 is unusually high or if it is normal, the following calculations should be done:

(((42 - 3) + (42 + 3)) / 2) x 0.98 = X
((39 + 45) / 2) x 0.98 = X
42 x 0.98 = X
41.16 = X

(((42 - 3) + (42 + 3)) / 2) x 1.02 = X
((39 + 45) / 2) x 1.02 = X
42 x 1.02 = X
42.84 = X

Therefore, as the mean price goes between $ 41.16 and $ 42.84, a value of $ 48 is unusually high.

HELP ME PLEASE I REALLY COULD USE IT BRAINLY GOES TO THE CORRECT ANSWER

Zanzabum

Answer:

y=x+8

Step-by-step explanation:

In order to get the output (y), you have to add 8 to the input (x).

18 + 8 = 26

35 + 8 = 43

86 + 8 = 94

therefore, x+8=y

What is the distance between A(-8, 4) and B(4, -1)?

Anettt [7]

Answer:

The distance between A(-8, 4) and B(4, -1) is 13 units.

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula given by:

$\displaystyle d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

We have the two points A(-8, 4) and B(4, -1). Let A(-8, 4) be (x₁, y₁) and let B(4, -1) be (x₂, y₂). Substitute:

$d=\sqrt{(4-(-8))^2+(-1-4)^2}$

Evaluate:

$d=\sqrt{(12)^2+(-5)^2}$

So:

$d=\sqrt{144+25}=\sqrt{169}=13\text{ units}$

The distance between A(-8, 4) and B(4, -1) is 13 units.
