Answer:

Below

Step-by-step explanation:

1 pound = 16 ounces

Therefore if you're looking for 8 ounces, divide $7.50 in half.

You get $3.75

Answer:

At this rate, the total cost of 8 ounce bag of trail mix would be $3.75.

Step-by-step explanation:

So first I found that for 1 LB (pound), there is 16 ounces so 8 oz is half of 16. If we know that, we have to divide 7.5 by 2 to get 3.75.

The answer to the question is that there are no points on the curve x3 + y3 = 9 in the xy-plane that have a tangent line that is horizontal.

The equation x3 + y3 = 9 is a cubic equation and is a non-linear equation. As such, it does not have any tangent lines that are horizontal. A tangent line is a line that just touches a point on a curve and has the same slope as the curve at that point. Since the equation is non-linear, the slope of the curve changes at each point, meaning that there cannot be any horizontal tangent lines.

To calculate the slope of the curve at any point (x,y), we use the formula m = (dy/dx) or m = 3*(x2/y2). At these points, the slope of the curve will not be zero, meaning that there is no horizontal tangent line at any point on the curve.

Therefore, the answer to the question is that there are no points on the curve x3 + y3 = 9 in the xy-plane that have a tangent line that is horizontal.

\(y-y_1=m(x-x_1)\)

Given the x1 and y1 = given point.

Substitution x1 = 2 and y1 = -8 in the equation.

\( \begin{cases} x_1 = 2 \\ y_1 = - 8 \end{cases} \\ y - ( - 8) = - 4(x - 2) \\ y + 8 = - 4(x - 2)\)

Hence, the solution is C choice.

\(y + 8 = - 4(x - 2)\)

To find the slope of line AB, we can use the slope formula:

slope of AB = (y2-y1)/(x2-x1) = (3-8)/(2-(-10)) = -5/12

Since we want to find the equation of a line parallel to AB and passing through point X(-5,10), we know that the slope of this new line will also be -5/12.

Now we can use the point-slope form of the equation of a line to find the equation of the line:

y - y1 = m(x - x1), where m is the slope of the line and (x1,y1) is a point on the line.

So, plugging in the values we know:

y - 10 = (-5/12)(x - (-5))

Simplifying:

y - 10 = (-5/12)x - (25/12)

y = (-5/12)x + (145/12)

This is the slope-intercept form of the equation of the line parallel to AB and passing through point X.

Both x and y have to be 90

Step-by-step explanation:

x and the 90 degree angle below it must be equal because the lines are parallel.

And y would also be the same as x

Answer: x = 90, y = 90

Step-by-step explanation:

         We can use vertical angles and corresponding angles to solve this question. Vertical angles are congruent to each other, so are corresponding angles. The little box shows that the angle is equal to 90 degrees.

Answer:

\(\boxed {\boxed {\sf b= \sqrt{192}}}\)

Step-by-step explanation:

Since this is a right triangle, we can use Pythagorean Theorem to find the sides.

\(a^2+b^2=c^2\)

where a and b are the legs and c is the hypotenuse.

In this triangle, 8 and x are the legs because they form the right angle. 16 is the hypotenuse because it is opposite the right angle.

\(a=8 \\c=16\)

Substitute the values into the formula.  

\(8^2+b^2=16^2\)

Solve the exponents.

\(64+b^2=256\)

Subtract 64 from both sides to isolate the variable.

\(64-64+b^2= 256-64 \\b^2=192\)

Take the square root of both sides.

\(\sqrt {b^2}=\sqrt{192}\\ b=\sqrt{192}\)

The missing side is equal to √192

The 99th percentile for the mean height of a random sample of 20 adult women is approximately 68.7 inches, which is 3.7 inches above the mean of 65 inches.

The 99th percentile for the mean height of a random sample of 20 adult women can be calculated using the normal distribution. The normal distribution is a bell-shaped curve that describes the probability of a given event occurring. In this case, the mean and standard deviation of the height of adult women is used to calculate the probability of the mean height of a sample of 20 adult women being a certain value. For the 99th percentile, this means that the probability of the mean of the sample of 20 adult women being equal to or less than the value of 68.7 inches is 99%. This value is 3.7 inches above the mean of 65 inches, which is the expected mean height of adult women.

Two point charges, q1 = 3.99 nC located at x = 0.205 m and q2 = 5.01 nC at x = -0.302 m, are placed on the x-axis. The electric field and direction at a given point can be calculated using the principle of superposition.

The electric field at a point due to a point charge is given by Coulomb's law, E = kq/r^2, where E is the electric field, k is Coulomb's constant (8.99 x 10^9 Nm^2/C^2), q is the charge, and r is the distance between the point charge and the point where the electric field is being measured. To calculate the net electric field at a point due to multiple charges, we use the principle of superposition, which states that the total electric field at a point is the vector sum of the electric fields due to each individual charge.

In this case, we have two charges, q1 = 3.99 nC and q2 = 5.01 nC. The electric field at a point P on the x-axis, due to q1, can be calculated as E1 = kq1/r1^2, where r1 is the distance between q1 and point P. Similarly, the electric field at point P due to q2 can be calculated as E2 = kq2/r2^2, where r2 is the distance between q2 and point P. To find the net electric field at point P, we add the electric fields vectorially, E_net = E1 + E2.

The probability of two planes having no cracks is 0.063 and The probability of no plane having critical cracks is 0.405.

(a) The probability of one plane having a critical crack is 10% or 0.10. The probability of two planes having detectable cracks is (0.21)^2 = 0.0441. The probability of two planes having no cracks is (0.69)^2 = 0.4761. So, the desired probability is 0.10 * 0.0441 * 0.4761 = 0.063.

(b) To find the probability that at least one plane has critical cracks, we can use the complementary probability approach, i.e., finding the probability that no plane has critical cracks and then subtracting it from 1. The probability of no plane having critical cracks is (0.90)^5 = 0.595. So, the desired probability is 1 - 0.595 = 0.405.

In terms of total spending, the federal government spent approximately $411 billion on Medicaid in fiscal year 2020.

Medicaid is a joint federal-state program that provides healthcare coverage for low-income individuals and families, as well as people with disabilities. The federal government and the states share the cost of the program, with the federal government typically contributing a larger share.

As mentioned earlier, the federal government pays approximately 63% of Medicaid costs, while states pay approximately 37%. The exact percentages can vary depending on the state and the specific Medicaid program being implemented.

In terms of total spending, the federal government spent approximately $411 billion on Medicaid in fiscal year 2020. This includes both federal Medicaid spending and administrative costs associated with running the program.

It is worth noting that the cost of Medicaid can vary from year to year and can be affected by changes in policy and funding. For example, during the COVID-19 pandemic, the federal government provided additional funding to states to help cover the cost of Medicaid and other healthcare programs.

We know that ]Ezra used 18 oz of cheddar, and he wants to use less cream cheese than cheddar, then if C represents the amount of cream cheese that he uses, we need to have:

C < 18 oz.

This means that C must be strictly smaller than 18 ounces. (While the option that you have marked means that C can be less than or equal to 18 oz).

The second option, 2 is a prime number, but not odd

Step-by-step explanation:

A prime number is a result of two other whole numbers multiplied by themselves. There is no whole number that you can multipy by itself to get 2 because 1 × 1 = 1 and 2 × 2 = 4. Therefore, it is a prime number. But, that does not mean it is an odd number because odd numbers are 1, 3, 5, 7, etc. and even numbers are 2, 4, 6, 8, etc.

To evaluate the integral Jx e^5x2 dx by making the substitution u = 5x^2, we need to first find the value of dx in terms of du. Taking the derivative of u with respect to x, we get du/dx = 10x, which can be rearranged to dx = du/10x.
Substituting this into the integral, we get:
Jx e^5x2 dx = J(u/10)e^u (du/10x)
Simplifying this expression, we get:
Jx e^5x2 dx = (1/10)Jue^u du
To evaluate this new integral, we can use integration by parts, with u = u and dv/dx = e^u. This gives us:
Jx e^5x2 dx = (1/10)(ue^u - J e^u du) + C
Resubstituting for u, we get:
Jx e^5x2 dx = (1/10)(5x^2e^5x^2 - Jx e^5x^2 dx) + C
Simplifying and rearranging, we get:
Jx e^5x2 dx = (1/20)x e^5x^2 + C
