Ginny has a package of 80 cards. There are 40 yellow cards
and 40 red cards.
If she randomly picks 4 cards, how many cards should she
expect to be yellow?

2 + 8 + 5 = 15 total candy bars.

8 twix, so picking a twix would be 8/15

5 crunch bars, picking a crunch would be 5/15, which reduces to 1/3

Probability of both: 8/15 x 1/3 = 8/45

Answer:

$11.20.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Changing the "a" value changes x-intercepts because when you distribute the "a" value to the binomials or the factored pairs to the right then the suitable x value which makes the quadratic equation also changes.

Answer:

The florist needs to order me 7 more red flowers then there will be enough for 21 bouquets, with no flowers left over.

Step-by-step explanation:

If she had given back 50 of the others then the florist would classify that as left over stock, so she would need to order and ask for 7 more.

1050 / 50 = 21

140/7 = 20

Answer:

Y-intercept or b = 2.5

X-intercept = 3.5

Step-by-step explanation:

The y-intercept is where the graph intersects on the y-axis, where x=0.

Thus, the y-intercept or b = 2.5.

The x-intercept is where the graph intersects on the x-axis, where y=0.

Thus, the x-intercept = 3.5.

Answer:

47°

Step-by-step explanation:

Answer:

(x - 3)² + (y + 1.5)² = 15.25

Step-by-step explanation:

Centre: midpoint of the diameter

(h,k) = (0+6)/2, (1-4)/2

= (3, -3/2)

Radius = ½(diameter)

Diameter = sqrt(6² + (-4-1)²)

sqrt(61)

Radius = sqrt(61)/2

Equation:

(x - h)² + (y - k)² = r²

(x - 3)² + (y + 1.5)² = 15.25

Answer:

x² - 6x + 9

Answer:

Step-by-step explanation:

Given that the wavelengths for X-rays with frequency [tex]3\times 10^{18}[/tex]

The distance between two peaks in a wave is called the wavelength.

The value of wavelength is equal to the wave velocity divided by the frequency.

That is written by

[tex]Wavelength=\lambda =\frac{v}{f}[/tex]

[tex]Wavelength =\frac{3\times 10^8}{3\times 10^{18}}[/tex]

[tex]=\frac{10^8}{10^{18}}[/tex]

[tex]=\frac{1}{10^{18}.10^{-8}}[/tex] (by using the property [tex]a^m=\frac{1}{a^{-m}}[/tex])

[tex]=\frac{1}{10^{18-8}}[/tex] (by using the property [tex]a^m.a^n=a^{m+n}[/tex])

[tex]=\frac{1}{10^{10}}[/tex]

[tex]=1\times 10^{-10}[/tex] m (by using the property [tex]\frac{1}{a^{m}}=a^{-m}[/tex])

Nerve cells ( neurones )

The nervous system is made up of nerve cells called neurons. Most body cells are round but neurones are not. They are stretched out into long thin fibres that can be over a meter long. Nerve impulses travel along nerve fibre in only one direction. It's function is to carry nerve impulses.

Answer:

f(x) is a negative number with a large absolute value

Step-by-step explanation:

The f(x) when x is a very small positive number  then it is a negative number with a large absolute value.

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable). In other words and the physical sciences, functions are indispensable for formulating physical relationships.

From the graph of the function F(x) below,

We can conclude that F(x) is a negative number with a large absolute value.

when x is a very small positive number.

Therefore, the correct option is A.

Answer:

The marginal-cost function is;

c'(x)= (20x-1)/(2√(400 + 10x² - x))

Completed question;

The cost of producing x bags of dog food is given by C(x) = 800 + √(400 + 10x² - x) where 0≤x≤55000. Find the marginal-cost function.

The marginal-cost function is c'(x)=

(Use integers or fractions for any numbers in the expression.)

Step-by-step explanation:

The marginal-cost function is c'(x)= = dC(x)/dx

Where;

C(x) = 800 + √(400 + 10x² - x)

c'(x) = d(800 + √(400 + 10x² - x) )/dx

Using function of function rule of differentiation or chain rule;

c'(x) = (20x-1)×(1/2√(400 + 10x² - x))

c'(x) = (20x-1)/(2√(400 + 10x² - x))

The marginal-cost function is;

c'(x)= (20x-1)/(2√(400 + 10x² - x))

Final answer:

The marginal-cost function c'(x) is 9.

Explanation:

Marginal-cost function:

Given cost function: C(x) = 800 + 400 + 10x - x

Find derivative of C(x): C'(x) = 10 - 1 = 9

Therefore, the marginal-cost function is c'(x) = 9

Answer:

$464

Step-by-step explanation:

Including 16% trip, she pays

100+16 = 116% of the cost

116/100 × 400

= 464

Answer:

Mary pay the movers $464.

400 x 0.16 = 64

400 + 64 = 464

Answer:

1/16

Step-by-step explanation:

So if you want to divide an amount equally, you divide the numbers. In this scenario, what you would do is this:

1/2 needs to be split 8 times

(1/2)/8

If you have something like this where the numerator is a fraction, then you multiply 2x8. that gives you 16, so now you add the 1 on top and you get 1/16.

Answer:

X = -1/3, 1/3

Step-by-step explanation:

6x^2 - x = 1

(subtract 1 from both sides)

6x^2 - x - 1 = 0

(factor)

(6x - 3) (6x + 2)

(simplify)

(2x - 1) (3x + 1)

(Solve for x in each parentheses)

2x-1= 0 and 3x+1=0

X= -1/2 X= -1/3

Answer:

x=-1/2,-1/3

Step-by-step explanation:

6x²-x = 1 <- Rewrite

       -1  -1 <- Subtract 1 from both sides

6x²-x-1 = 0

x²-x-6 = 0 <- Slide the x²'s coefficient over to the variable with no coefficient through multiplication

(x-3)(x+2)=0 <- Factor

(x-3/6)(x+2/6)=0 <- Divide the 6 back out and simplify

(x-1/2)(x+1/3)=0 <- Simplify

(2x-1)(3x+1)=0 <Bring the denominator in front of the x

2x+1 = 0 and 3x+1 = 0 <- Seperate the two and solve

    -1    -1             -1    -1

  2x = -1 and      3x = -1

   x = -1/2 and      x = -1/3

so

x=-1/2,-1/3

Answer:

C

Step-by-step explanation:

Look at the coefficients in the expression: -3 and 12.  The largest number that divides them both is 3.  That means you can factor out either a 3 or a negative 3.  Try 3.

3(-x - 4) is not on the list of answers.  Also, it's unusual to factor out a value that leaves a negative coefficient on x.

Try factoring out -3.

-3(x + 4) is answer choice C.

Bonus

Because this is a multiple-choice question without a "non of these" option, you can solve the problem by expanding--multiplying out--the answers!

A. 3(x + 4) = 3x + 12 ...nope, not it

B. 3(x - 4) = 3x -12 ...nope, not it

C. -3(x + 4) = -3x -12 ...bingo!

Answer:

  Door 3  diagonal 3√10 feet

Step-by-step explanation:

The diagonal of a rectangle is the hypotenuse of a right triangle whose legs are the side lengths of the rectangle. That is, the diagonal of a 9 ft by 3 ft rectangle will have length ...

  d = √(9² +3²) = √90 = 3√10

Any "9 ft by 3 ft" figure that has a diagonal different from this is not a rectangle. To fit the rectangular opening, we want a rectangular door—one with a diagonal of 3√10 feet.

Answer:

[tex]214in^{2}[/tex]

Step-by-step explanation:

First we find the area of the regular hexagon.

Area = 4√3*24

Area ≈ [tex]166in^{2}[/tex]

Now we find the area of the other shaded region, which is a parallelogram.

Area = bh

The base of the parallelogram is congruent to one of the sides of the regular hexagon, which means the base is 8 inches.

To find the height, we have to look at the right triangle next to the parallelogram. As we can see, the long leg of the right angle is perpendicular to the base of the parallelogram, and since the height of a parallelogram is perpendicular to its base, we find out that the height of the parallelogram is 6 inches.

Now we find the area.

Area = 6*8

Area = [tex]48in^{2}[/tex]

Now we add the both areas.

[tex]166 in^{2}+48 in^{2}=214 in^{2}[/tex]

The area of the composite figure is ≈ [tex]214 in^{2}[/tex]
