Armando has 3 blue shirts, 3 green shirts,

and 2 red shirts. He has 3 pairs of jeans

and 4 pairs of cargo pants. He is equally

likely to wear any of the shirts with any

pair of pants. What is the probability that

Armando will wear a green shirt with cargo pants?

Answers

Answer:

0.2143 = 21.43% probability that Armando will wear a green shirt with cargo pants.

Step-by-step explanation:

Probability:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of independent events:

The probability of two independent events is the multiplication of their separate probabilities.

Green shirt:

3 green shirts, out of 3 + 3 + 2 = 8 shirts.

So 3/8 probability of green shirts.

Cargo pants:

4 cargo pants, our of 4 + 3 = 7.

So 4/7 probability of cargo shirts.

Green shirt and cargo pants:

[tex]p = \frac{3}{8} \times {4}{7} = \frac{12}{56} = \frac{3}{14} = 0.2143[/tex]

0.2143 = 21.43% probability that Armando will wear a green shirt with cargo pants.

5 is the answer

here we have hypoteaus and base

so by using pythagoreaus theorem

p^2 = h^2 - b^2

p^2 = 13^2 - 12^2

p^2 = 169 - 144

p^2 = 25

p = root under 25

p = 5

Answer:

5 cm

Step-by-step explanation:

A^2+B^2=C^2

12^2+B^2=13^2

144+B^2=169 (You have to subtract 144 from both sides to get B^2 by its self)

-144       = -144

B^2= 25 (To get rid of the square you have to find the square root)

Square root of 25 = 5cm

Help 30 point question!

Answers

You're given 3 points (x, y) on the circle with equation

x ² + y ² + Dx + Ey + F = 0

and you have to use these known points on set up 3 equations involving D, E, and F.

For the point (3, -1), this means when x = 3, y = -1, so

3² + (-1)² + 3D - E + F = 0

→   3D + (-1)E + 1F = -10

The next point (-2, 4) gives

(-2)² + 4² - 2D + 4E + F = 0

→   (-2)D + 4E + 1F = -20

And from the last point (6, 8),

6² + 8² + 6D + 8E + F = 0

→   6D + 8E + 1F = -100

Gabe​ Amodeo, a nuclear​ physicist, needs 90 liters of a ​50% acid solution. He currently has a 30% solution and a 60% solution. How many liters of each does he need to make the needed 90 liters of ​50% acid​ solution?

Answers

Answer:

You need two equations: one for solution amounts and one for alcohol amounts.

Step-by-step explanation:

90 = X + Y

45 = (0.6)/X + (0.3)Y

Here X = amount of 60 % solution and Y = amount of 30 percent solution. Note that percentages have been converted to decimal amounts in the second equation.

From here you have to solve two equations with two unknowns. Easiest to solve first equation for X = 90 - Y, then substitute into second equation. this get you one equation in one unknown. Solving you you will get

X = 30 liters and Y = 60 liters.

Find the dimensions of the rectangle of maximum area with sides parallel to the coordinate axes that can be inscribed in the ellipse 4x^2 16y^2

Answers

Answer:

The answer is below

Step-by-step explanation:

Find the dimensions of the rectangle of maximum area with sides parallel to the coordinate axes that can be inscribed in the ellipse 4x² + 16y² = 16

Solution:

Given that the ellipse has the equation: 4x² + 16y² = 16

let us make x the subject of the formula, hence:

4x² + 16y² = 16

4x² = 16 - 16y²

Dividing through by 4:

x² = (16 - 16y²)/4

x² = 4 - 4y²

Taking square root of both sides:

[tex]x=\sqrt{4-4y^2 }\\[/tex]

The points of the rectangle vertices is at (x,y), (-x,y), (x,-y), (-x,-y). Hence the rectangle has length and width of 2x and 2y.

The area of a rectangle inscribed inside an ellipse is given by:

Area (A) = 4xy

A = 4xy

[tex]A=4(\sqrt{4-4y^2} )y\\\\A=4y\sqrt{4-4y^2}=4\sqrt{4y^2-4y^4} \\\\The\ maximum\ area\ of\ the\ rectangle\ is\ at\ \frac{dA}{dy}=0\\\\ \frac{dA}{dy}=4(\frac{4-8y^2}{\sqrt{4-4y^2} } )\\\\4(\frac{4-8y^2}{\sqrt{4-4y^2} } )=0\\\\4-8y^2=0\\\\8y^2=4\\\\y^2=1/2\\\\y=\frac{1}{\sqrt{2} }\\\\x=\sqrt{4-4(\frac{1}{\sqrt{2} })^2}=\sqrt{2}[/tex]

Therefore the length = 2x = 2√2, the width = 2y = 2/√2

Answer: y = 5/2x - 4

Step-by-step explanation:

the equation is y = ax + b (a ≠ 0)

because the slope of the line is 5/2 => a = 5/2

=> the equation is y = 5/2.x - 4

PETS Each month Travis spends $20 for premium food$10 for treats $18 for grooming, and $3 for toys for his pet. Write an expression that could be used to determine the amount he spends on these items for his pet over a period of 12 months.

Answers

Answer:

$492 per year

Step-by-step explanation:

The first step we take towards solving this question is to add all the numbers we were given as money spent(excluding that of the month)

$20 + $10 + $18 + $3 = $41 per month

This means that a total of $41 was spent per month.

Going further, since we're told it's 12 months, we then multiply it by 12, and thus, we have

$41 * 12 = $492 per year

Therefore, the total money spent is $492 per 12 months, or per year

O 33.3%

Answers

Answer:

Percent of increase in weight = 33.33% Approx.

Step-by-step explanation:

Given:

Old weight = 60 pound

New weight = 80 pound

Find:

Percent of increase in weight

Computation:

Percent of increase in weight = [(New weight - old weight)/Old weight]100

Percent of increase in weight = [(80 - 60)/60]100

Percent of increase in weight = [(20)/60]100

Percent of increase in weight = 33.33% Approx.

A 16-oz bottle of parmesan cheese costs $5.78, while an 8-oz bottle costs $3.97. Which is the better buy? Round
your answer to the nearest cent if necessary.

Answers

Answer:

The 16-oz bottle is a better buy

Step-by-step explanation:

Find the better buy by finding which one has a lower price per ounce:

Calculate the price per ounce of both bottles by dividing the cost by the number of ounces

5.78/16

= 0.36

3.97/8

= 0.5

Since 0.36 is smaller than 0.5, the 16 ounce bottle is a better buy.

Answer:

The 16-oz bottle of parmesan cheese is the better buy.

Step-by-step explanation:

It is the better buy because, if you compare the prices and the ounces, I say that the 16-oz is the best buy.
