Answer:

-5 + 10n = -85

10n = -80

n = -8

Answer:

= -8

Step-by-step explanation:

-5(1 - 2n)=-85

(-5(1)) + (-5(-2n)) = -85

-5 + 10n = -85

10n = -85 + 5

10n = -80

n = -80/10

n = -8

Answer:

x = -5

Step-by-step explanation:

You're asking for the solution?  the x value that makes the equation true?

First perform the multiplication:  5 - 10x + 8x = 15

Combining like terms, we get -10 = 2x.

Dividing both sides by 2 yields x = -5.

Answer:

Complete question statement is;

n 2009, the worlds largest pumpkin weighed 1,725 kilograms. An average sized pumpkin weighs 5000 grams. The 2009 world record pumpkin weighs ___ kilograms more than the average sized pumpkin

Step-by-step explanation:

The answer to this is that world record pumpkin weighs 1720 kilograms more than the average sized pumpkin

In one kilogram, there are 1,000 grams i

so 5,000 grams means to be equivalent to 5 kilograms.

Now since we are in same metric units, we can now compare the largest weight and the average weight which would be;

= 1725 - 5

= 1720 kilograms

So the difference between largest weighed and average weighed pumpkin is 1720 kilograms

Final answer:

The world-record pumpkin weighs 13.5 kilograms more than an average-sized pumpkin, with the weight of the average pumpkin being 0.243 kilograms and the approximate world-record weight being 13.7 kilograms.

Explanation:

To solve how many kilograms more the world-record pumpkin weighs than an average-sized pumpkin, we need to calculate the difference in their weights. Given that an average-sized pumpkin weighs 243 grams, which is equivalent to 0.243 kilograms (since 1 kg = 1000 g), we need to know the weight of the world's largest pumpkin in kilograms.

We're given that the least precise measurement is 13.7 kg. Assuming that the world-record pumpkin weighs this amount, we subtract the mass of the average pumpkin (0.243 kg) from the world-record pumpkin mass (13.7 kg).

So the calculation is:

13.7 kg - 0.243 kg = 13.457 kg

To express our answer to the same precision as the least precise measurement, we round it to the tenths place. Therefore, the world-record pumpkin weighs 13.5 kilograms more than an average-sized pumpkin when rounded to the nearest tenth of a kilogram.

Answer:

10 Packages

Step-by-step explanation:

The rectangular vegetable garden has a dimension of Length 20 feet and Width 40 feet.

Perimeter of a Rectangle=2(L+W)

=2(20+40)=2(60)=120 feet

Since the store sells fencing in 4-yard packages, let us convert our perimeter to Yards.

1 Yard= 3 Foot

x Yard =120 Feet

Cross Multiply

3x=120

x=40 Yards

The Perimeter =40 Yards

Therefore the number of Packages which Troy and his Mom needs:

Perimeter of the Garden÷Length Per Package

=40÷4

=10 Packages

Troy and his mom would need 20 Packages of Fencing.

Step-by-step explanation:

The surface area is the sum of the areas of the faces.

There are 4 faces that are 5 cm wide. Their respective heights (from front, over the top) are ...

  1 cm, 2.5 cm, 2 cm, 2.3 cm

for a total height of 7.8 cm. Thus, those 4 faces have a total area of ...

  (5 cm)(7.8 cm) = 39.0 cm^2

__

The two trapezoidal faces each have bases of length 1 and 2 cm, and a "height" of 2.3 cm. Together, their areas are ...

  A = 2×(1/2)(b1 +b2)h = (b1 +b2)h

  A = (1 cm +2 cm)(2.3 cm) = 6.9 cm^2

__

The surface area of the entire trapezoidal prism is then ...

  total area = base area + lateral area = 6.9 cm^2 +39 cm^2

  total area = 45.9 cm^2

The student's answer of 57.4 cm^2 is not correct. (We don't know where that calculation came from.)

Sam's description = [tex]3x+3[/tex], Kim's description =  [tex]5x-7[/tex]

Step-by-step explanation:

Given:

Kim and Sam were each given the same pair of numbers.

Sam's description of the two numbers was:

The larger number is 3 more than three times the smaller number.

Kim's description of the two numbers was:

Five times the smaller number decreased by 7 is the larger number.

Question asked:

Which equation represents the situation?

Solution:

Let smaller number = [tex]x[/tex]

According to Sam's description of the two numbers, the equation will be:-

Larger number = 3 more than three times the smaller number

                         = [tex]3x+3\ (eq1)[/tex]

According to Kim's description of the two numbers was, the equation will be:-

Larger number = Five times  decreased by 7

                         = [tex]5x-7\ (eq2)[/tex]

By equating  both equation:-

[tex]5x-7=3x+3\\ \\ Subtracting\ both\ sides\ by \ 3x\\ \\ 5x-3x-7=3x-3x+3\\ \\ 2x-7=3\\ \\ Adding\ both\ sides\ by\ 7\\ \\ 2x-7+7=3+7\\ \\ 2x=10\\ \\ Dividing\ both\ sides\ by\ 2\\ \\ x=5[/tex]

Smaller number = [tex]x[/tex] = 5

Larger number = [tex]3\times5+3=15+3=18[/tex]

Therefore, equations represents the situation are [tex]3x+3[/tex] and [tex]5x-7[/tex]

Answer:

Extra 4 cups to make up 11 cups a day

Step-by-step explanation:

Here we have that Jan obtains 15% of her fluid needs from food, therefore, she gets the remaining 85 % from drinking water

If the recommended daily intake = 2.7 liters  or 91.3 oz

And she already consumes 48 oz of water and  16 oz of milk

Note milk is equivalent to 0.87 water therefore total intake = 48 + 16*0.87= 61.92 oz

She needs to take additional (91.3 - 61.92) = 29.4 oz or 3.68 ≈ 4 cups extra to meet her recommended daily dosage.

Answer:

[tex]t=\frac{67-60}{\frac{12}{\sqrt{16}}}=2.33[/tex]    

Step-by-step explanation:

Data given and notation  

[tex]\bar X=67[/tex] represent the sample mean

[tex]s=12[/tex] represent the sample standard deviation

[tex]n=16[/tex] sample size  

[tex]\mu_o =60[/tex] represent the value that we want to test

t would represent the statistic (variable of interest)  

State the null and alternative hypotheses.  

We need to conduct a hypothesis in order to check if the true mean is higher than 60, the system of hypothesis would be:  

Null hypothesis:[tex]\mu \leq 60[/tex]  

Alternative hypothesis:[tex]\mu > 60[/tex]  

If we analyze the size for the sample is < 30 and we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:  

[tex]t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}[/tex]  (1)  

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".  

Calculate the statistic

We can replace in formula (1) the info given like this:  

[tex]t=\frac{67-60}{\frac{12}{\sqrt{16}}}=2.33[/tex]

C. 3/$5.79 = 13/x

Step-by-step explanation:

We can write the fact that 3 markers cost $5.79 as a proportion:

3/$5.79

Let x represent the unknown cost of 13 markers. Since 13 markers cost x, we have the following proportion:

13/x

The cost changes along with the number of markers purchased, and so the two proportions are equivalent.

3/$5.79 = 13/x

Answer:

If he maintains the same rate he'll hit 180 home runs over the next three seasons.

Step-by-step explanation:

If he maintains the same rate of homeruns per season as he did in 1987 the number of home runs he'll hit over the next three seasons is the rate from 1987 multiplied by 3. We have:

number of home runs = 3*rate

number of home runs = 3*60

number of home runs = 180

If he maintains the same rate he'll hit 180 home runs over the next three seasons.

Answer:

See the attached figure.

Step-by-step explanation:

Total people = 90

The people that liked khakis = 25

The people that liked t shirts = 55

out of 25 people that liked khakis 15 liked t shirts

See the attached figure, the table on the left represents the given data

While the table on the right represent the table after finding the unknowns.

So,

The people that liked tank tops = V = 90 - 55 = 35

People that liked tank tops out of 25 people that liked khakis=Z=25-15=10

The people that liked jeans = W = 90 - 25 = 65

And X = 55 - 15 = 40

And Y = W - X = 65 - 40 = 25

So, the table on the right is the two way table summarizing the data.

Answer:

No

Step-by-step explanation:

Say the price of 1 apple is x and the price of 1 orange is y. Then, we can write the two equations:

4x + 4y = 10

6x + 6y = 15

We can try to solve this by elimination, which means getting rid of one variable so that we're left with only 1 variable to solve for. Multiply the top equation by 3 and the bottom equation by 2:

3 * (4x + 4y) = 10 * 3  ⇒  12x + 12y = 30

2 * (6x + 6y) = 15 * 2  ⇒  12x + 12y = 30

Subtract the bottom equation from the top:

  12x + 12y = 30

-  12x + 12y = 30

______________

   0   +   0   =   0

Since we result in 0 = 0, that means any values of x and y we put into the equations will work, so we cannot find a unique price.

Answer:

The intensity on a screen 70 ft from the light is 1.728 foot candle.

Step-by-step explanation:

Given that,

The magnitude of  intensity [tex]I[/tex] of light varies inversely as the square of the magnitude of distance D from the source.

That is

[tex]I\propto \frac{1}{D^2}[/tex]

Then,

[tex]\frac{I_1}{I_2}=\frac{D_2^2}{D_1^2}[/tex]

Given that,

The magnitude of intensity of illumination on a screen 56 ft from a light is 2.7 foot-candle.

Here,

[tex]I_1[/tex]=2.7 foot-candle, [tex]D_1[/tex]= 56 ft

[tex]I_2[/tex]=?, [tex]D_2[/tex]= 70 ft.

[tex]\frac{I_1}{I_2}=\frac{D_2^2}{D_1^2}[/tex]

[tex]\Rightarrow \frac{2.7}{I_2}=\frac{70^2}{56^2}[/tex]

[tex]\Rightarrow \frac{I_2}{2.7}=\frac{56^2}{70^2}[/tex]

[tex]\Rightarrow {I_2}=\frac{56^2\times 2.7}{70^2}[/tex]

[tex]\Rightarrow {I_2}=1.728[/tex] foot-candle

The intensity on a screen 70 ft from the light is 1.728 foot candle.

[tex]x^2+y^2=81[/tex]

Step-by-step explanation:

The standard form of the equation of a circle of radius r, with centre (h, k) is given as:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

We are required to write an equation in standard form for the circle with radius 9 centered at the origin.

Substituting these values into the Standard form of the equation of a circle given above:

[tex](x-0)^2+(y-0)^2=9^2\\x^2+y^2=81[/tex]

The standard form is: [tex]x^2+y^2=81[/tex]

The equation of the circle whose center is at (0,0) and the radius is 7 is [tex]\rm x^2+y^2=49[/tex] and the equation of the circle whose center is at (0,0) and the radius is 9 is [tex]\rm x^2+y^2=81[/tex].

Given :

The circle with a radius 9 is centered at the origin.

The following steps can be used in order to determine the equation in standard form for the circle:

Step 1 - The generalized equation of the circle is given below:

[tex]\rm (x-h)^2+(y-k)^2=r^2[/tex]    --- (1)

where (h,k) represents the coordinates of the center of the circle and r is the radius of the circle.

Step 2 - According to the given data, the center of the circle is at (0,0) and the radius of the circle is 9.

Step 3 - Substitute the values of all the known terms in equation (1) in order to determine the equation of the circle.

[tex]\rm x^2+y^2=81[/tex]

Step 4 - Now, the equation of the circle whose center is at (0,0) and the radius is 7 is given by:

[tex]\rm x^2+y^2=49[/tex]

Answer:

No, This is not a valid Probability Distribution

Step-by-step explanation:

Probability [Neighbour walks with Beagle] = 20%

Probability [Neighbour walks with Golden Retriever] = 70%

Probability [Neighbour walks alone] = 30%

Disjoint Events are the events that have zero probability of occurring together. If all the three above items are disjoint, it means that it can never happen that two of them happen together.

The total (summed) probability of a valid probability distribution, with disjoint sets = 1 . In given case, total probability = 0.2 + 0.7 + 0.3 = 1.2 ; i.e > 1.

So, this probability distribution with stated disjoint events is not a Valid Probability distribution.

Final answer:

The given percentages (20% with the beagle, 70% with the golden retriever, 30% walking alone) add up to 120%, which exceeds the total probability of 100%. Thus, they do not constitute a valid probability distribution.

Explanation:

The situation described about the neighbor walking with her pets and alone presents individual probabilities of different events. If these events are indeed disjoint, meaning they cannot happen at the same time, then to determine if the given percentages represent a valid probability distribution, they must satisfy two main conditions: the sum of all probabilities must be equal to one (100%), and each individual probability must be between 0 and 1 inclusive.

Calculating the sum of the given probabilities: 20% (for walking with the beagle) + 70% (for walking with the golden retriever) + 30% (for walking alone) equals 120%, which exceeds 100%. This indicates that the given percentages do not contain a valid probability distribution because they do not sum to one, violating one of the fundamental characteristics of a probability distribution.
