A 7th grade homeroom was asked if they would
prefer a hamburger, pizza, or hot dog. Calculate
the relative frequency ( or experimental
probability) of choosing a hot dog using this
chart.
12%
20%
16.7%
1.66 %
The probability of choosing a hot dog is 16.7%
Relative frequency and probabilityProbability is the likelihood or chance that an event will occur
Probability = Expected outcome/Total outcome
From the figure;
Total outcome = 4 + 6 + 2
Total outcome = 12
Since there are 2 hotdogs, hence the probability of choosing a hot dog is given as:
Pr(hot dog) = 2/12
Pr(hot dog) = 0.1667
Hence the probability of choosing a hot dog is 16.7%

If the mass of 9 chocolate bars is 540 g, find the mass of 6 such chocolate bars.
Answer:
360g
Step-by-step explanation:
9 = 540g
divide both sides by 9
1 = 60g
multiply both sides by 6
6 = 360g
Answer:
The answer is 360 g
Step-by-step explanation:
GivenMass of 9 chocolate bars = 540 gTo Find;Mass of 6 chocolate bars = ?Here, we know that mass of 9 chocolate bars is 540 g
so, for mass of one chocolate bar divide 540 by 9 we get,
540 g ÷ 9 = 60 g
Here, The mass of each chocolate bar is 60 g.
Now, for mass of 6 chocolate bar multiply by 60 by 6 we get,
60 g × 6 = 360 g
Thus, The mass of 6 such chocolate bars is 360 g.

I need quick help with this!! 15 PTS POSSIBLE!!! i know for sure its not 3/50, but i think its 3/20? and explain your reasoning.
Answer:
3/20
Step-by-step explanation:
Given:
Probability that it is Monday and that a student is absent is 3/100
Probability that a randomly selected day of the school week is monday is 1/5
To Find:
What is the probability that a student is absent given that today is Monday.
Solve:
It may be different if it were on a Wednesday. Because we expect fewer absentees on Wednesday than on Monday/ Friday. In these cases the conditional probability, P(absent/weekday) would differ depending on the day of the week.
3/100 ÷ 1/5 = 3/20
The probability that a student is absent on a Monday is 3/20

Cottage cheese is being sold in different size containers. The sizes and prices are given below: 4 - 5 ounce containers for $5. 00 1 - 12 ounce container for $3. 24 1 - 16 ounce container for $4. 19 Which container is the better buy? a. The 5 ounce container is the better buy. B. The 12 ounce container is the better buy. C. The 16ounce container is the better buy. D. The containers have the same unit price.
Division is the process of finding the number of times a number is multiplied by itself. The 16-ounce container is the better buy.
What is Division?
The division is the process of finding the number of times a number is multiplied by itself.
The prices of the different size containers are given to us,
4-5 ounce containers for $5. 00
1-12 ounce container for $3. 24
1-16 ounce container for $4. 19
Now, find the cost of the cheese per ounce when we buy the minimum cheese and when we but the maximum amount of cheese.
1. For the first Container, 4-5 ounce containers for $5.00
If we buy 4 ounces of cheese, then the cost of each ounce of cheese will be $1.25 for each ounce, while if we buy the maximum amount of cheese therefore 5 ounces for $5 then the cost of each ounce of cheese will be $1.
2. For, the second container, 1-12 ounce container for $3.24
If we buy 1 ounce of cheese, then the cost of each ounce of cheese will be $3.24 for each ounce, while if we buy the maximum amount of cheese therefore 5 ounces for $5 then the cost of each ounce of cheese will be $0.27.
3. For, the third container, 1-16 ounce container for $4.19.
If we buy 1 ounce of cheese, then the cost of each ounce of cheese will be $4.19 for each ounce, while if we buy the maximum amount of cheese therefore 16 ounces for $4.19 then the cost of each ounce of cheese will be $0.26.
Thus, if we buy the maximum amount of cheese from each of the boxes, the third box will be the cheapest.
Hence, The 16-ounce container is the better buy.

Explain why Justine is correct or incorrect.
the second claim of justine is that the only angle of rotation that shows rotational symmetry is 120 degree is correct.
A rotational symmetry implies that the shape remains the same when rotated
Justine's claim is correct
How to determine the true statementThe angle of rotational symmetry is calculated as:
[tex]\theta = \frac{360}n[/tex]
Where n represents the number of sides.
From the complete question, the shape is a regular hexagon.
This means that n = 6.
So, we have:
[tex]\theta = \frac{360}6[/tex]
Divide
[tex]n = 60[/tex]
Other angles of rotational symmetry are:
[tex]n = 60, 120, 180, 240.....[/tex]
120 degrees is part of the list of possible angles of rotational symmetry.

Shana inherited land from her late grandmother. The land originally cost $25,000 when
her grandfather had purchased it in 1945. If the value of the land increased by about 5%
annually, how much did it cost in 2015?
Answer:
760660.638388
Rounded: 760660.64
Step-by-step explanation:
You can use an exponential function. that would be a(b)^x or 25000(1.05)^x
From 1945 to 2015 there is a 70-year gap, so you would substitute 70 for x. That would get you 760660.638388, so in 2015, the value of the land would be 760660.64 if you round up.

Justin wants to buy a new pair of jeans. If the jeans were originally $50.00, but are on sale with a 30% discount, how much will Justin have to pay for the jeans?
Answer:
$35.00
Step-by-step explanation:
Step 1: Multiply 30 by 50.
30 × 50 = 1500Step 2: Divide 1500 by 100.
1500 ÷ 100 = 15Step 3: Subtract 15 from 50.
50 - 15 = $35.00Answer:
35 dollars.
Step-by-step explanation:
The easiest way of calculating discount is, in this case to multiply the normal price is $50 by 30 then divide it by 100. So, the discount is equal to $15. To calculate the sales price, simply deduct the discount of $15 from the original price $50 then get $35 as the sales price.

How does scientific notations work?The number is written in the form [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
Better readability due to compact representationIts value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.The given expression is:
[tex](3.1 \times 10^5) \times (2.2 \times 10^7)[/tex]
Evaluating the multiplication, we get:
[tex]3.1 \times 2.2 \times 10^5 \times 10^7 = 6.82 \times 10^{5 +7} = 6.82 \times 10^{12}[/tex]
It is because of exponent rule that [tex]a^b \times a^c = a^{b+c}[/tex], and because of commutative property of addition.
