Using the normal distribution, it is found that there is a 0.284 = 28.4% probability that a randomly selected package of grapes weighs more than a  randomly selected package of honeydew slices.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, for each variable, [tex]\mu_G = 3.25, \sigma_G = 0.91, \mu_H = 4.51, \sigma_H = 2.02[/tex]

For the subtraction, we have that:

[tex]\mu_D = \mu_G - \mu_H = 3.25 - 4.51 = -1.26[/tex]

[tex]\sigma_D = \sqrt{\sigma_G^2 + \sigma_H^2} = \sqrt{0.91^2 + 2.02^2} = 2.2155[/tex]

The probability that a randomly selected package of grapes weighs more than a  randomly selected package of honeydew slices is P(D > 0), which is 1 subtracted by the p-value of Z when X = 0.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0 - (-1.26)}{2.2155}[/tex]

[tex]Z = 0.57[/tex]

[tex]Z = 0.57[/tex] has a p-value of 0.7157.

1 - 0.715 = 0.284

0.284 = 28.4% probability that a randomly selected package of grapes weighs more than a  randomly selected package of honeydew slices.

Find the value of y when x = 14 and x = 15:

Answer:

y=-3/2x+5

Step-by-step explanation:

The line intersects with points (2,2) and (4,-1). Slope intercept form is y=mx+b, where m is slope and b is the y intercept. The y intercept appears to be at (0,5), so b=5. As for the line, the formula for calculating slope is y2-y1/x2-x1 (the order of the points you use actually does not matter; you just have to make sure both coordinates from the same point are placed in the same part of the formula). -1-2/4-2=-3/2. Therefore, the slope is -3/2 (or -1.5 if you want a decimal).

Answer:

Step-by-step explanation:

1 3/10 x 18

(1 x 10 +3)/10 = 13/10

13/10 x 18 = (13 x 18) / 10 = 234/10 = (234/2) / (10/2) = 117/5 = 23 2/5 (a fraction is a division)

The answer to the expression showing the product of 1 3/10 x 18 is 23 2/5.

Given is an expression showing the product of 1 3/10 x 18, we need to solve it,

To multiply a mixed number by a whole number, you can convert the mixed number to an improper fraction and then multiply the fractions.

Here's how you can solve the problem:

Step 1: Convert the mixed number to an improper fraction:

1 3/10 = (1 × 10 + 3) / 10 = 13/10

Step 2: Multiply the fractions:

13/10 x 18/1 = (13 x 18) / (10 x 1) = 234 / 10

Step 3: Simplify the fraction, if possible:

234/10 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:

234/10 = (234 ÷ 2) / (10 ÷ 2) = 117/5

Therefore, 1 3/10 x 18 = 117/5.

Alternatively, you can express the answer as a mixed number by dividing the numerator by the denominator:

117 ÷ 5 = 23 with a remainder of 2

So, the final answer is 23 2/5.

Step-by-step explanation:

A rational function is the ratio of two polynomials. It will have a vertical asymptote if there is a real denominator zero that is not matched by one in the numerator.

Polynomials in general may or may not have real zeros, and two polynomials may have the same zero. Hence conditions may exist for a rational function not to have any vertical asymptotes.

An example with no vertical asymptotes is ...

Answer:

  a) see attached

  b) 41

  c) 56.2%

Step-by-step explanation:

a) We have drawn three circles, labeled D, C, B representing students who have dogs, cats, and birds, respectively. Based on the given information we can fill numbers in for all three animals (7), cats and dogs only (15), and birds only (8).

Then we can fill in cats and birds only by subtracting the number with all three. That will be 12 -7 = 5. Birds and dogs only is similarly filled by subtracting all three to get 20 -7 = 13 birds and dogs only.

Dogs only is found by subtracting the numbers in multiple categories from the total number of dogs: 90 -13 -7 -15 = 55. Cats only is found the same way: 68 -5 -7 -15 = 41.

The completed diagram is shown in the attachment. (We haven't figured the quantity for "none.")

__

b) 41 students have cats only

__

c) The total number with dogs only, cats only, or birds only is ...

  55 +41 +8 = 104

Of the 185 total students, that is 104/185 ≈ 56.2%.

56.2% of students have exactly one type of animal as a pet.

Step-by-step explanation:

Plug in -2 for x ....

f(x) = -2^3 - 7(-2)^2 + 3

     = -8 - 28 + 3

     = -36 + 3

     = -33

Plug in 3/4 for x ....

f(x) = 3/4^3 - 7(3/4)^2 + 3

     = 27/64 - 63/16 + 3

The put in decimals ....

27/64 = .422

63/16 = 3.938

Put the decimals back into the equation ....

     = .422 - 3.938 + 3

     = -3.516 + 3

     = -.516

Applying the steps, the result of the line integral is 99.

The curve is:

[tex]f(x,y,z) = xy i + 9y^2 j[/tex]

The vector field is:

[tex]r(t) = (x(t), y(t)) = (16t^6, t^4)[/tex]

Applying the vector field at the curve, we have that:

[tex]f(t) = (16t^{10}, 9t^8)[/tex]

The derivative of the vector field is:

[tex]r^{\prime}(t) = (96t^5, 4t^3)[/tex]

[tex]f(t)r^{\prime}(t) = (16t^{10}, 9t^8)(96t^5, 4t^3) = 1536t^{15} + 36t^{11}[/tex]

Hence, the line integral is:

[tex]I = \int_{0}^{1} (1536t^{15} + 36t^{11}) dt[/tex]

[tex]I = 96t^{16} + 3t^{12}|_{t = 0}^{t = 1}[/tex]

5% error

Step-by-step explanation:

% error = (estimation - actual value)/actual value * 100%

Trayvon's estimation is 63 and the actual value is 60, so our expression is:

(63 - 60)/60 * 100

63 - 60 = 3, so we get:

3/60 * 100

And 3/60 = 0.05, so now we have:

0.05 * 100 = 5

The percent error of Trayvon’s guess is 5%

"It is the absolute difference between an observed value and the actual value."

"It is the ratio of the absolute error of the measurement to the actual value."

"It is the relative error multiplied by 100."

For given example.

Trayvon’s guess is 63 balls.

[tex]V_o=63[/tex]

The actual number of balls is 60.

[tex]V_A=60[/tex]

The absolute error is,

[tex]\Rightarrow A=|V_o-V_A|\\\\\Rightarrow A=|63-60|\\\\\Rightarrow A=3[/tex]

The relative error is,

[tex]\Rightarrow R=\frac{A}{V_A} \\\\\Rightarrow R=\frac{3}{60}\\\\ \Rightarrow R=0.05[/tex]

The percent error is,

[tex]\Rightarrow P=R\times 100\\\\\Rightarrow P=0.05\times 100\\\\\Rightarrow P=5\%[/tex]

Therefore, the percent error of Trayvon’s guess is 5%
