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.

Answer:

Lol I'll help you. So for the 1st problem, you need to subtract 7x from 4x but if your looking for and answer then x=2. For the 2nd problem subtract 3x-5x and 7 + 9 which brings you to -2x - 16 which means you would have to find x in this problem which means x has to be a negative. The negative answer is x= -32 since a negative x a negative is a positive. Which brings you to 16-16 and then 0. For the third one, you need to change the problem. Turn it into 5x - x = 4 + 8 which brings you to 4x = 12 making x =3. and for number 4 you need do the same as we just did and do 11x - 6x - 3x and then do 20 - 6 which brings you to 2x = 14 which makes  x=7.

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.

The total distance he travelled in kilometer is 8.2 km

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

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!

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.

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%

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

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
