How can we interpret probability?

Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.

Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).

Since it is given that:

The chance of a customer receiving a blue pen = 0.008The chance of a customer receiving a blue tote bag = 0.04

Both probabilities are too close to 0, than 1. So they both are very unlikely to occur.

Thus, it is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen (Option B).

A block of iron has dimensions of 1 cm x 2 cm x 5 cm and has a
mass of 799
What is its density? (V=lxwxh)

Answers

Answer:

79.9 units

Step-by-step explanation:

Hi there,

Before solving this problem, it is important to know the formula:

D = [tex]\frac{m}{v}[/tex].

D = density

m = mass

v = volume

Since we are given the mass and volume, we can simply enter these values into the formula to find the density of the block.

D = [tex]\frac{799}{10}[/tex]

D = 79.9

Therefore, the density of the block of iron is 79.9 units. I wrote units since you did not specify the unit for the mass. Hope this answer and explanation helps.

Cheers.

Facts:

Justin jogs 3 2/3 miles every morning

Jogs 4 6/10 miles every evening.

Miles jogged per day=?

To solve this question,add the 2 fractions.This makes sense because let's say you ran 3 miles in the morning and 2 miles in the evening, nothing more nothing less, and you wanted to find how much you ran in a day, you'd add these 2 nummbers.

3 2/3 + 4 6/10

Step 1: Add the whole numbers

3 2/3 + 4 6/10

3+4= 7

7 + 2/3 + 6/10

Step 2: Find a common denominator between 10 and 3

10x1= 10

10x2= 20

10x3= 30 (works for both 3 and 10)

7 + __ + __

30 30

Step 3: Change the neumerators

Now when adding fractions this way, you have to multiply and change the neumerator:

In the 1st fraction, the original denominator was 3. And 3x10= 30, right? So you must also multiply the neumerator by 10 so that they are equivalent to each other

2x10= 20

In fraction #2, the neumerator was 6. 6x3= 18

7 + 20 + 18

30 30

7+38/30= 7 38/30= 8 8/30 miles per day

Facts:

Last year, the tree was 5 11/12 feet long.

This year, the tree is 7 2/3 feet long.

How many feet did it grow?

Convert to decimals and subtract:

7 2/3= 7.66667

5 11/12= 5.9166667

7.66667- 5.916667= about 1.75, which becomes 1 3/4

It grew 1 3/4 feet

because the line in the middle of 60 and 70 is 65 but the red does not go to that line but it is in the 60s so therefore the answer is C)65degrees Celsuis

The answer is 17 degrees Celsius. Since it is Celsius, we have to look at the bottom line. It is between 10 and 20 and over the middle line (which resembles 15). Therefore, it is 17.
