A new store is handing out small gifts to the customers who come in. Elizabeth is handing out pens of various colors.She has determined that the chance of a customer receiving a blue pen is 0.008. Ricardo is handing out tote bags of various colors. He has determined that the chance of a customer receiving a blue tote bag is 0.04. What statement describes the likelihood of a customer getting a blue tote bag or a blue pen?

It is very unlikely that a customer gets a blue tote bag, but it is very likely that a customer gets a blue pen.

It is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen.

It is very likely that a customer gets a blue tote bag, but it is very unlikely that a customer gets a blue pen.

Answers

Answer:

99% sure it's B !!!

Step-by-step explanation:

the likelyhood of getting a blue pen is microscopic, not even a 1% chance and the likelihood of getting a blue tote bag is also pretty small

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)

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).

Can u figure out the surface area and volume i will give brainlest

Answers

Answer:

Volume: 120

SA: 400

Step-by-step explanation:

Volume = Bh

Volume = (1/2 x b x h) h

Volume = (1/2 x 6 x 4) 10

Volume = 120

SA = 2B + Ph

SA = 2(1/2 x b x h) + (s + s + s)h

SA = 2(1/2 x 6 x 4) + (5 + 5 +6) 10

SA = (24 + 16) 10

SA = 40 x 10

SA = 400

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
