This problem can be solved by setting up two equations to represent the number of enchilada and taco meals being served. Let x be the number of enchilada meals and y be the number of taco meals. Then we have:

x + y = 250 (representing the total number of meals)

5x + 7y = 1500 (representing the total cost of the food)

Solving these equations using methods such as substitution or elimination will give you the values of x and y, i.e. the number of enchilada and taco meals being served at the party.

Answer:

x + y = 250 (representing the total number of meals)

5x + 7y = 1500 (representing the total cost of the food)

If we randomly select someone who was aboard the titanic, what is the probability that person is a man, given that he died is 1360/1517.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty. For pupils in Class 10, probability is a crucial subject since it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.

Probability that person is a man, given that he died,

P(x) = Favorable outcome/Total

= 1360/ 1517.

The probability of selecting exactly 2 white marbles out of 5 marbles from container b is approximately 0.144 or 14.4%.

To calculate the probability of selecting exactly 2 white marbles out of 5, we can use the binomial coefficient formula, which is given by:

P(X=k) = (n choose k) × [tex]p^{k}[/tex] × [tex]1-p^{n-k}[/tex]

where n is the total number of trials (in this case, 5), k is the number of successful outcomes (in this case, 2), p is the probability of success (in this case, the probability of selecting a white marble), and (n choose k) is the binomial coefficient.

First, let's find the probability of selecting a white marble from container B, which is given by:

p = (number of white marbles) / (total number of marbles) = (300 + 1) / (300 + 100 + 1) = 301 / 401

Next, we can use the formula to find the probability of selecting exactly 2 white marbles:

P(X=2) = (5 choose 2) × p² * (1-p)⁽⁵⁻²⁾ = (10) × (301/401)² × (100/401)³ = 0.144

So the probability of selecting exactly 2 white marbles out of 5 is approximately 0.144 or 14.4%.

There is no way to accurately answer this question as there are too many variables to consider, such as the population size and crime rate of the state.

There is no way to accurately answer this question as there are too many variables to consider. The population size of the state would be an important factor in calculating the number of murders per 100,000 residents. The population size of the state would determine how many people are in the state with an automatic weapon and therefore how many potential murders could occur. Additionally, the crime rate of the state would be an important factor in determining the number of murders per 100,000 residents as it would indicate whether or not there would be a higher propensity for crime in the state. Additionally, the availability of other weapons, such as handguns or knives, would also be a factor as it could reduce or increase the number of murders with automatic weapons. All of these factors, as well as others, make it impossible to accurately determine the number of murders per 100,000 residents in a state with 1 thousand automatic weapons.

The required general solution of the differential equation in implicit form y = [tex][(3/2) * (15x + C) * x^{-3}]^{-3/2}[/tex].

The differential equation is a nonlinear equation and cannot be solved exactly by standard methods. One way to approach a solution is to try to find a substitution that transforms the equation into a separable form, where the variables can be separated and integrated separately. A common approach is to make the substitution y = v^(-2/3), which transforms the equation into:

3x^2 * (2/3) * v^(-5/3) * v' + 6x * v^(-2/3) = 15 * v^(-5/3)

Dividing both sides by v^(-5/3), we get:

3x^2 * (2/3) * v' + 6x * 3 * (2/3) * v^(1/3) = 15

This is now a separable differential equation, and we can integrate both sides to find the general solution:

∫(3x^2 * (2/3) * v' dx) = ∫(15 dx) + C

(2/3) * x^3 * v = 15x + C

v = (3/2) * (15x + C) * x^(-3)

Finally, substituting back for y = v^(-2/3), we get the general solution:

y = [tex][(3/2) * (15x + C) * x^{-3}]^{-3/2}[/tex]

This is the general solution of the differential equation in implicit form. To find an explicit form, one could solve for C using initial or boundary conditions.

The height of the cable from the road at a point 150 feet from the center of the bridge is 12.5 feet.

The equation for a parabolic cable is given by

y = ax^2 + bx + c

where x is the horizontal distance from the center of the bridge, y is the height of the cable from the road and a, b, and c are coefficients determined by the shape of the cable.

The height of the cable at the center of the bridge is 0

so, c = 0

The height of the cable at the towers is 80 feet

so, at x = ±300 feet, y = 80

Plugging in these two points into the parabolic equation, we can solve for a and b.

Using the formula

[tex]y = ax^2 + bx[/tex]

we have two equations:

[tex]80 = a * (300)^2 + b * 300 and 0 = a * (0)^2 + b * 0[/tex]

Solving for a and b, we find that

a = -0.000167 and b = 50

Finally, at x = 150 feet from the center,

the height of the cable from the road is

[tex]y = -0.000167 * (150)^2 + 50 * 150 = 50 - 0.000167 * 22500 = 50 - 37.5 = 12.5 feet.[/tex]

The unit rate is equal to 3 dollars per book.

The unit rate can be determined by dividing the total amount of money raised by the number of books sold.

In the context of the situation, the point (6, 18) means 6 books were sold to raise a total amount of $18.

In Mathematics, the unit rate is sometimes referred to as unit price and it can be defined as the price that is being charged by a seller for the sale of a single unit of product.

In order to determine the unit price, we would use the following mathematical expression;

Unit price = Total raised/Number of books sold

Unit price = 6/2 = 12/4 = 18/6 24/8

Unit price = 3 dollars per book.

In conclusion, we can reasonably infer and logically deduce that the point (2, 6) means 2 books were sold at Garfield Elementary to raise a total amount of $6.

There are 15 test scores that are 85 or greater out of a total of 30 test scores.

The third quartile, Q3, is the median of the upper half of the set of data. To determine the number of test scores that are 85 or greater, we must first find the median of the upper half of the data set. The formula to calculate the median is

Median = (n+1)/2

where n is the number of observations in the data set. In this case, n is 30. Plugging this into the formula we get

Median = (30+1)/2 = 15.5

Therefore, there are 15.5 test scores that are 85 or greater.

To calculate the number of test scores that are 85 or greater, we subtract 15.5 from 30. This gives us 14.5 test scores that are 85 or greater. Since 14.5 is not a whole number, we can round up to 15 test scores that are 85 or greater. Therefore, there are 15 test scores that are 85 or greater out of a total of 30 test scores.

If the store sells 80 feet of rope, it makes a profit of $6.4.

The money made from selling a product, which should be higher than its cost price, is referred to as the profit. It is the gain from any type of commercial activity. In other words, a gain or profit is judged to have occurred when the selling price (SP) of a product exceeds its cost price (CP).

Given the amount a hardware store pays for buying nylon rope is represented by the equation,

y = 0.12x

the cost price of rope is y = 0.12x

and the amount the hardware store charges when selling the rope is represented by the graph,

from graph,

we find the coordinates (1, 0.20) (2, 0.40)

the equation of a line is y = mx + c

since the graph passes from the origin (0, 0) so the equation of the graph will be,

y = mx

and  m = (.40 - 0.20)/(2 - 1)

m = 0.20

selling price of rope = y = 0.20x

where x is the length of rope in feet and y is the amount,

If the store sells 80 feet of rope,

the cost price of  80 feet of rope is

y = 0.12x

y = 0.12(80)

y = $9.6

and the selling price of 80 feet of rope is

y = 0.20x

y = 0.20(80)

y = $16
