Joe is training to run in a half marathon in two months. This week he ran 1, 200,000 millimeters on Monday, 2, 400 meters on
Wednesday, and 4.6 kilometers on Friday. What is the total distance in kilometers that he ran this week?
TI
The total distance he travelled in kilometer is 8.2 km
What is distance?Distance is the total movement of an object without any regard to direction.
Given:
On Monday he walked = 1, 200, 000 mm
On Tuesday he walked= 2,400 m
On Wednesday he walked = 4.6 km
As, 1mm = 1/100,000
1,200,000 mm = 1.2 Km
and, 1 m =1/1000 km
2400m = 2.4 km
Hence, the total distance he travelled = 1.2+ 2.4 + 4. 6 = 8.2 km

12x^4 divided by 3x^2
Answer:
12x^4 divided by 3x^2 is 4x^2
Step-by-step explanation:
So what you basically do is 12 divided by 3 which is 4.
When you divide exponents, its basically subtracting the exponent while leaving the coefficient of x or whatever the same.
When you multiply exponents, you are literally adding the exponent while leaving the coefficient alone.
When you add exponents, you gotta have the same exponent and you can't add something like x^3 + x^7 because they don't have the same unit of the exponent, but you can only do that with multiplication or division.
So, since you are dividing, you "subtract" the exponent of x^4 by x^2 so you get x^2 since 4-2 equals 2.
I hope this is at a point where you can understand!
Hope this helps!

79 and
113?
Ta
Answer
How to enter your answer
%
Answer:
68 %
Step-by-step explanation:
The Empirical rule formula states that:
• 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.
• 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
• 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
Mean of 96 and a Standard deviation of 17
Applying , the first empirical rule for 1 standard deviation from the mean, we have:
μ - σ
96 - 17
= 79
μ + σ
96 + 17
= 113
Therefore, the percentage of IQ scores that are between 79 and 113 is 68%

The population of a small country is 2.279 million and its national debt is $6.03 billion. What is the amount of debt per person? Round to the nearest whole number.
Answer:
$2,646 per person
Step-by-step explanation:
In this scenario, we are given the ratio of debt:population size of roughly 6.03billion (numerator) for every 2.279million people (denominator). Therefore in order to find the amount of debt per person we simply divide the debt by the population in order to reduce the population to 1 and see how much debt every individual would have. Like so...
6,030,000,000 dollars / 2,279,000 people = x
2,645.89 dollars / 1 person = x
Rounding this value up to the nearest dollar would mean that every individual has an estimated debt of 2,646 dollars.
3 5 of students at a school are boys. If there are 2610 students at the school, how many are girls?
Answer:
1044 girls in the school
Step-by-step explanation:
3/5*2610=1566 boys
2610-1566-1044 girls
it should be 1044 because
3/5=.6 or 60%boys and 40% girls
2610 * 60% or .6 = 1566 boys
2610 - 1566boys = 1044 girls
or
2610 * 40% or .4 = 1044 girls
so there are 1044 girls at the school

The price of a technology stock was $9.71 yesterday today the price rose to $9.84 find the percentage increase round your answer to the nearest 10th of a percent
Answer:
1.34%
Step-by-step explanation:
In order to find the percentage increase between these two prices, we must first find the difference in price. We calculate this by subtracting the final price by the initial price like so...
$9.84 - 9.71 = 0.13
Now we divide the difference by the initial price to find what percentage of the initial price this difference is, since this percentage difference was added to the initial price to get the new and final price point.
0.13 / 9.71 = 0.013388 ... multiply by 100 to get percent value
0.013388 * 100 = 1.3388% or 1.34% rounded.

Customers at the Palace Pro Shop receive a 10% discount if they are members. All customers must pay 7% in sales tax. The function f(x)=0.9x is used to determine the price of an item after the 10% member discount, where x is the regular price of the item. The function g(x)=1.07x is used to determine the total amount customers pay for a purchase after all discounts are applied. Which function can be used to determine T(x), the total amount a member pays for an item with a regular price of x dollars?
Answer:
The total amount a member pays for an item with a regular price of x dollars is T (x) = 0.963x.
Step-by-step explanation:
Key points:
Discount is subtracted from the regular price of an item.Sales tax is added to the regular price of an item.It is provided that the customers receive a 10% discount if they are members and all customers must pay 7% in sales tax.
Two functions are provided are:
f (x) = 0.90x ; the price of an item after the 10% member discount
g (x) = 1.07x ; the total amount customers pay for a purchase after sales tax is applied.
Compute the total amount a member pays for an item with a regular price of x dollars as follows:
T (x) = Discount × Sales Tax
= 0.90 × 1.07 × x
= 0.963x.
Thus, the total amount a member pays for an item with a regular price of x dollars is T (x) = 0.963x.
One month, two search engines were used to conduct a total of 3.52 billion online searches. Search engine A was used to conduct 0.66 billion more searches than search engine B. How many searches were conducted on each search engine?
FAST PLS
Answer:
Search Engine A = 2.09 billion searches.
Search Engine B = 1.43 billion searches.
Step-by-step explanation:
Engine A + Engine B = 3.52 billion
Search engine A was used to conduct 0.66 billion more searches than search engine B
A = 0.66 billon + B
Hence:
0.66 billion + B + B = 3.52 billion
2B = 3.52 billion - 0.66 billion
2B = 2.86 billion
B = 2.86 billion/2
B = 1.43 billion searches.
A = 0.66 billion + B
A = 0.66 billion + 1.43 billion
A = 2.09 billion searches.
Therefore:
Search Engine A = 2.09 billion searches.
Search Engine B = 1.43 billion
The probability that an employee at a company uses illegal drugs is 0.08. The probability that an employee is male is 0.62. Assuming that these events are independent, what is the probability that a randomly chosen employee is a male drug user?
Answer: 0.0496
Step-by-step explanation:
If events are said to be independent it means that the probability of one happening does not affect the probability of the other.
In calculating the probability that an employee is both male and a drug user using independent events, multiply the probabilities of the individual events to find the probability of the the events happening together.
P(A) * P(B) = P(A and B)
0.08 * 0.62 = 0.0496
Probabilities are used to determine the chances of events.
The probability that a randomly chosen employee is a male drug user is 0.0496
Represent the two events as A and B, such that:
[tex]P(A) = 0.08[/tex]
[tex]P(B) =0.62[/tex]
So, the probability that a randomly chosen employee is a male drug user is calculated as:
[tex]P(A\ and\ B) =P(A) \times P(B)[/tex]
This gives
[tex]P(A\ and\ B) =0.08 \times 0.62[/tex]
Multiply
[tex]P(A\ and\ B) =0.0496[/tex]
Hence, the probability that a randomly chosen employee is a male drug user is 0.0496

A single 6-sided die is rolled twice. Find the probability of getting a 3 the first time and a 3 the second time. Express the probability as a simplified fraction.
Answer:
1/36
Step-by-step explanation:
The event is mutually exclusive event. The occurrence of one foew not affect the other.
If a die is rolled once, the total outcome will be 6 since a die has 6 faces.
Probability = expected outcome/total outcome
If 3 is gotten when a die is rolled, the expected outcome will be 1.
Probability of getting a 3 will be 1/6
The probability of getting a3 the second time is also 1/6
The probability of getting a 3 the first time and a 3 the second time = 1/6×1/6 = 1/36
he cost of manufacturing a particular videotape is C(x)90009x, where x is the number of tapes produced. The average cost per tape, denoted by , is found by dividing by x. Find .
Answer:
The average cost per tape is 10.
Step-by-step explanation:
The cost of manufacturing a particular videotape is :
C(x) = 9000+9x
Where
x is the number of tapes produced.
We need to find the value of average per tape i.e. [tex]\lim_{x \to 9000} \bar C(x)[/tex]
[tex]\bar C(x)=\dfrac{9000+9x}{x}\\\\=\dfrac{9000}{x}+9\\\\ \lim_{n \to 9000} \bar C(x)=\dfrac{9000}{9000}+9\\\\=1+9\\\\=10[/tex]
So, the average cost per tape is 10.
