find the missing values in the ratio table .then write the equivalent ratios .

one would be   2pi - 5pi/18 = 31pi/18
another positive one is 31pi/18 + 36pi/18  = 67pi/18
and the negative angle is -5pi/18 - 36pi/18  = -41pi/18

The answer is  b

Final answer:

To find the coterminal angles with -5π/18, we have to add or subtract multiples of 2π. By doing so, we find out that the coterminal angles are −23π/18, 13π/18, and -41π/18. So, the correct option is c.

Explanation:

To find angles that are coterminal with a given angle, we have to add or subtract multiples of 2π. This is because a full rotation around the unit circle is 2π radians. Angles that differ by an exact multiple of 2π radians are considered as coterminal.

Therefore, we can get the coterminal angles of −5π/18 by adding and subtracting multiples of 2π. This gives us the angles, −23π/18 and 13π/18 (for positive angles) and −41π/18 (for a negative angle). Thus, the option (c) −23π/18, 13π/18, 31π/18 is correct.

1 and 3/4 would be the mixed number that represents the length of each piece. You would get this number by dividing 7 by 4 :)

Final answer:

When a 7-foot board is divided into 4 equal pieces, each piece will be 1.75 feet, or, as a mixed number, 1 3/4 feet.

Explanation:

To figure out the length of each piece when a 7-foot board is divided into 4 equal parts, we perform division. We divide the total length of the board by the number of pieces. That is, 7 ÷ 4 = 1.75.

This is a decimal number. To express it as a mixed number, we remember that '.75' is the same as '75/100', and this fraction can be simplified to '3/4'. So, 1.75 feet is the same as 1 3/4 feet. Therefore, each piece of board will be 1 3/4 feet long.

Distance to travel = 20 m.
Let us determine the time, t, that each participant took to complete 20 m.

Barbara:
Average speed = (3 m)/(2 s) = 1.5 m/s
t = 20/1.5 = 13.3 s

Mark:
t =  5 s

Carlos:
y = x + 1
where
y = 20 m
x = time, t
Therefore
t =x = y - 1 = 20 - 1 = 19 s

Summary:
Barbara:  13.3 s

Final answer:

To find the lower sum, divide the interval into subintervals, evaluate the function at the left endpoint of each subinterval, and sum up the areas of the rectangles with those minimum values as heights.

Explanation:

To approximate the area of the region using lower sums, we need to calculate the lower sum by dividing the interval into subintervals of equal width, finding the minimum value of each subinterval, and summing up the areas of the rectangles with those minimum values as heights.

In this case, we have the function y = sqrt(1-x^2). Let's say we divide the interval into n subintervals. The width of each subinterval would be (b-a)/n, where a and b are the lower and upper limits of the interval.

To find the minimum value of each subinterval, we can evaluate the function at the left endpoint of each subinterval. Let's call these points x1, x2, x3,..., xn. Then, the lower sum is given by: Lower Sum = (b-a)/n * (f(x1) + f(x2) + f(x3) + ... + f(xn)).

To check if the lower sums you calculated are correct, make sure you are using the left endpoints of the subintervals and that the calculation is accurate.

how do we get the coefficient for the each term? well, the first coefficient is 1, and all subsequents are "the product of the current coefficient and the exponent of the first element divided by the exponent of the second element on the next term", so, that's a mouthful, but for example,

for the 5th term of the expansion, how did we get 210?  well, is just 120 * 7 / 4.

for the 6th term, how did we get 252?  well, is just 210 * 6 / 5.

recall that if the exponent is 10, that means the expansion will be 11 terms, and therefore the middle term will be the 6th one.

so, just combine the 6th term away.

A digit is a number in one of the places, so for example the number 54 has two digits; a tens place digit (5) and a ones place digit (4).

Say the mystery number is a two digit number = xy
* that's not x times y but two side by side digits.

Info given:
the sum of the digits of a two-digit number is 6
x + y = 6
if the digits are reversed, yx the difference between the new number and the original number is 18.

**To obtain the number from digits you must multiply by the place and add the digits up. (Example: 54 = 10(5) + 1(4))

Original number = 10x + y
Reversed/New number = 10y + x

Difference:
10y + x - (10x + y) = 18
9y - 9x = 18
9(y - x) = 18
y - x = 18/9
y - x = 2

Now we have two equations in two variables
y - x = 2
x + y = 6

Re-write one in terms of one variable for substitution.
y = 2 + x
sub in to the other equation to combine them.
x + (2 + x) = 6
2x + 2 = 6
2x = 6 - 2
2x = 4
x = 2

That's the tens digit for the original number. Plug this value into either of the equations to obtain y, the ones digit.

2 + y = 6
y = 4

number "xy" = 24

Yes the treasury can determine whether the gold bar is really weighing 500 ounces.

We can use the equation:

7 x + 11 y = 500

where x is the amount of the 7 ounce weights while y is the amount of 11 ounce weights.

 

We know that x and y should be whole numbers therefore this is solved through trial and error.

By trial and error I got:

x = 7 and y = 41

So that;

7 * 7 + 11 * 41 = 500

49 + 451 = 500

500 = 500

 

Hence they can use 41 11-ounce weights and 7 7-ounce weights to test

The answer to your question is that she can make 17 trains of 10 cubes so the answer is 17 

She will pack 1 crate that holds 1,000 and 25 stacks that hold 10.
1,250-1,000=250
250÷10=25

Shawna can pack an order of 1,250 blocks using 1 crate for the thousands and 25 stacks for the tens.

To pack 1,250 blocks using crates and stacks, we need to break down the total number of blocks into thousands and tens:

Step 1: Determine the number of crates (each crate holds 1,000 blocks). 1,250 blocks divided by 1,000 equals 1 crate (1,000 blocks).Step 2: Subtract the blocks already packed in crates: 1,250 - 1,000 = 250 blocks.Step 3: Determine the number of stacks (each stack holds 10 blocks). 250 blocks divided by 10 equals 25 stacks (250 blocks).Therefore, Shawna can pack the order with 1 crate and 25 stacks.

The statement "a sample of n = 9 scores is randomly selected from a population with m = 80 and s = 9 is false.

What is a normal distribution?

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

It is given that:

A sample of n = 9 scores is randomly selected from a population with m = 80 and s = 9.

As we know,

Z = (x - u)/s

Z = 3

x = 83

s = 9

3 = (83 - u)/9

27 = 83 - u

u = 83 - 27 = 56

Thus, the statement "a sample of n = 9 scores is randomly selected from a population with m = 80 and s = 9 is false.

Final answer:

To find points where the tangent plane to an ellipsoid is parallel to a plane, calculate the gradient vector of the ellipsoid and set it proportional to the normal vector of the given plane, then solve the resulting system for  (x, y, z).

Explanation:

To find all the points where the tangent plane to an ellipsoid is parallel to a given plane, you first need to consider the equation of the ellipsoid and the equation of the tangent plane.

The ellipsoid can be described by the general equation  f(x, y, z) = 0, while the tangent plane at a point on the ellipsoid can be described by the gradient of f at that point, given as  ∇f.

The gradient, which is a vector, gives us the normal to the tangent plane at the given point.

For a tangent plane to be parallel to another plane, their normal vectors must be proportional.

So, if we have the normal vector of the given plane, we can set up an equation with the gradient of the ellipsoid, and solve for the points (x, y, z) that satisfy this condition.

It requires solving a system of equations where the coefficients of the normals to both planes are proportional.

These points  (x, y, z) will be the points of tangency where the ellipsoid's tangent plane is parallel to the given plane.

We use the calculus concepts of partial derivatives to find the gradient vector and algebra to solve for the unknowns corresponding to the points of tangency.

The probability that at least one of the five light bulbs is defective is approximately 26.61%. This is found by calculating the probability that all bulbs work ([tex]0.94^5[/tex]) and subtracting that from 1.

The student is asking about the probability of having at least one defective light bulb in a pack of five, given a defect rate of 6%. To calculate this, we will use the complement rule, which states that the probability of at least one success is equal to 1 minus the probability of zero successes (no defective bulbs).

First, we calculate the probability that a bulb is not defective, which is 94% or 0.94 (since 100% - 6% = 94%). Since the bulbs are independent, the probability that all five bulbs are not defective is:

[tex](0.94)^5[/tex]

The probability that at least one bulb is defective is thus:

1 - [tex](0.94)^5[/tex]

Using a calculator, this gives us:

[tex]1 - (0.94^5) \approx 1 - 0.7339 \approx 0.2661 or 26.61%[/tex]

So, there is approximately a 26.61% chance that at least one of the five light bulbs is defective.

The probability that at least one of the light bulbs is defective is approximately 0.264909 or 26.49%.

To find the probability that at least one of the light bulbs is defective, we can use the complement rule.

The complement rule states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring.

In this case, the event of interest is that at least one light bulb is defective. The complement of this event is that none of the light bulbs are defective.

Given that 6% of the light bulbs are defective, the probability that any one light bulb is not defective is 1 - 0.06 = 0.94.

Since each light bulb operates independently of the others, the probability that none of the five light bulbs are defective is [tex]\((0.94)^5\)[/tex].

Therefore, the probability that at least one of the light bulbs is defective is [tex]\(1 - (0.94)^5\)[/tex].

Let's calculate it:

P(at least one defective) = 1 - (0.94)^5

P(at least one defective) = 1 - 0.735091 = 0.264909

So, the probability that at least one of the light bulbs is defective is approximately 0.264909 or 26.49%.

Answer:

2/35

Step-by-step explanation:

The only way we can solve this problem is to assume that the given complement of pieces is of a full kit before one went missing. The total number of pieces in the kit is ...

... 9 + 8 + 12 + 6 = 35

Of those, 2 are red with four holes. Thus the probability that a randomly chosen piece is red with 4 holes is 2 out of 35, or 2/35.

____

If this is the kit contents after the piece went missing, we have no way of knowing the color or hole count of the missing piece. If the kit is supposed to contain 13 blue pieces, for example, then the probability is zero that the missing piece is red.

Final answer:

The probability of a specific event is determined by dividing the number of ways this event can occur by the total number of possible outcomes. In this case, the probability of selecting a red piece with four holes from the toy building kit is the ratio of the quantity of four-holed red pieces to the total quantity of pieces in the kit.

Explanation:

The question refers to the probability of a specific event in a set of outcomes related to a toy building kit. In this case, the event is selecting a red piece with four holes. Probability can be defined mathematically as (Number of ways event can occur)/(Total number of outcomes). Specifically, in your case, you would calculate the number of four-holed red pieces within the whole toy building kit. Divide that by the total number of pieces in the entire kit, including the missing one.

Using an example with different objects for clarity, consider if there are 10 pieces in the set, and 3 of them are four-holed red pieces, the probability of the selected piece being a four-holed red piece would be 3/10 or 0.3 (once converted to decimal form). This method can now be applied to your toy building set once you identify the total number of pieces in the set and the number of these that are four-holed red pieces.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

In a proportional relationship, the value of the constant of proportionality is always equal to the ratio of the x and y for a directly proportional relationship and is equal to the product of x and y for an inversely proportional relationship.

Since am wants to write an equation to represent a proportional relationship with a constant of proportionality of 6. Therefore, the equation can be written as,
