ANSWER FOR BRAINLIEST!!! NOW!!!

Answer:

75%

Step-by-step explanation:

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:

(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:

a. 0.4333

b. 255

Step-by-step explanation:

The maximum Error E is 1.3

approximately normal test scores,

Standard Deviation, SD is 6.5

a).

Level of confidence = 99.7%

critical value of z for a two tailed test and 0.3% level of significance is 3

since the sample mean is within 0.5 of the true population mean

hence, the standard dev of mean is given by

[tex]Z_{\alpha}[\frac{\sigma}{\sqrt{n}} ]=E[/tex]

where E = 1.3

[tex]Z_{\alpha}=[/tex] 1.3

[tex]\frac{\sigma}{\sqrt{n}} =\frac{E}{Z_{\alpha}} \\\\\frac{\sigma}{\sqrt{n}} =\frac{1.3}{3}[/tex]

hence the Std of the mean is 0.4333 (to 4 d.p.)

b).

The sample size is computed as follows

making n the subject of formular of the above equation

[tex]\sqrt{n} =\frac{3\sigma}{1.3}} \\\\\sqrt{n} =\frac{3\times 6.5}{1.3}} \\\\n=(\frac{3\times 6.5}{1.3}})^2[/tex]

hence,

n = 255

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:

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:

  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:

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:

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:

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.

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]

Answer:

The final price with tax is 15,921.75‬, and the total tax added was 971.75‬

Step-by-step explanation:

To find the final cost, you multiply the cost of the product by the tax rate plus one.

For this problem, you multiply 14,950 by (0.065 + 1) to get the answer

Answer:

$15,921.75

Step-by-step explanation:

1. Multiply the cost of the car by the sales tax rate.

14950*.65= 971.75

2. Then add this amout to the original cost of the car.

14950 + 971.75= $15,921.15

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.
