Subtract using a number line.

kow [346]

The difference of the numbers given as -3.3 - (-0.6) is -2.7

<h3>How to subtract the numbers using a number line?</h3>

The difference of the numbers is given as

-3.3 - (-0.6)

Open the brackets, in the above expression

So, we have:

-3.3 - (-0.6) = -3.3 + 0.6

The above expression means that we make a mark on the number line at point 0.6 and then move the points on the number line to the left by 3.3 units.

So, we have the result to be:

-3.3 - (-0.6) = -2.7

This means that the last position on the number line is -2.7

Hence, the value of the difference of the numbers given as -3.3 - (-0.6) is -2.7

A waitress believes the distribution of her tips has a model that is slightly skewed to the left, with a mean of $8.30 and a s

kondaur [170]

Answer:

probability = 0.9286

Step-by-step explanation:

given data

mean = $8.30

standard deviation = $4.70

waits parties over a weekend of work = 60

solution

when we earn at least $550 in 60 parties

so average per party will be x = $\frac{550}{60}$

average x = 9.1667

so now we get here z value that is

$z = \frac{x-\mu }{\sigma }$ ...............1

put here value and we get

z = $\frac{9.1667-8.30}{4.70}$

z = 0.184404

P(x>9.1667) = P(z>0.184404)

use standard normal table

probability = 1 - 0.0714 = 0.9286

Find the measure of each exterior angle of a regular 56-gon. Round to the nearest tenth.

Allisa [31]

Answer: The measure of each exterior angle is 6.4°.

Step-by-step explanation:

Since we have given that

Number of sides = 56

We have to find the measure of each exterior angles:

As we know the formula :

$\text{ measure of each exterior angle}=\frac{360^\cir}{\text{Number of sides}}\\\\\text{ measure of each exterior angle}=\frac{360}{56}\\\\\text{ measure of each exterior angle}=6.4^\circ$

Hence, the measure of each exterior angle is 6.4°.
