We have the following linear equation:

5x - 2y = -10

In the standard form, we have:

-2y = -5x - 10

y = 5x/2 - 5

For x = 0, we have y = -5, and, for y = 0, we have x = 2

Therefore, to graph this equation, we just need to draw a line passing through (0,-5) and (2,0).

The value of the standard normal random variable z (z0) such that P(z ≤ z0) = 0.7090 is 0.54.

To calculate the value of the standard normal random variable z (z0), we need to use a standard normal distribution table or a calculator that can compute standard normal probabilities such that P(z ≤ z0) = 0.7090, follow these steps:

1. Identify the given probability: P(z ≤ z0) = 0.7090.
2. Look up the given probability in a standard normal distribution table or use an online calculator or software.
3. Find the corresponding z-score (z0) for the given probability.

Using a standard normal distribution table or an online calculator, the corresponding z0 value for P(z ≤ z0) = 0.7090 is approximately 0.54. Therefore, the value of the standard normal random variable z (z0) such that P(z ≤ z0) = 0.7090 is 0.54.

Thus, the number of volume read by both Eva and Maria in total 2 weeks is 8.

Slope is a crucial topic in economics because it's used to gauge how quickly things are changing.

The slope expresses how quickly the dependent variable changes when the independent variable changes. The line becomes steeper as the slope increases.

Given data:

Now,

Let the number of weeks at which both read the equal number of volume be x.

Total number of volume be y

So,

For Eva: y = 4 + 2x

For Maria: 0 + 4x

Equating both equations:

4 + 2x = 4x

4x - 2x = 4

2x = 4

x = 4/2

x = 2

Number of volumes read by each girl:

For Eva: y = 4 + 2(2)= 8

For Maria: 0 + 4(2) = 8

Thus, the number of volume read by both Eva and Maria in total 2 weeks is 8.

Step-by-step explanation: Took the test, no thanks neeeded :)

The least possible measure of ∠ADC is 1 degree, and the greatest possible measure of ∠ADC is 178 degrees.

To find the least possible measure of ∠ADC, we need to start with the smallest possible measure of ∠ADB and ∠BDC, which is 1 degree. In this case, the sum of the measures of ∠ADB and ∠BDC is 2 degrees, so the measure of ∠ADC must be 178 degrees.

To find the greatest possible measure of ∠ADC, we need to start with the largest possible measure of ∠ADB and ∠BDC, which is 89 degrees. In this case, the sum of the measures of ∠ADB and ∠BDC is 178 degrees, so the measure of ∠ADC must be 2 degrees.

Answer:

70

Step-by-step explanation:

Let the no of books bought be x

The cost price of 1 book is 5x

No of the missing book is 15

The remaining book is x-15

The selling price of 1 book is 87

Selling price of (x-15) book is 87

Hence the number of books can be calculated as follows

8(x-15)-5x= 90

8x-120-5x= 90

8x-5x= 90+120

3x= 210

x= 210/3

= 70

Hence the number of books bought is 70

Answer:

the answer to the question is C

The length and width of the room should be 50 feet, and the height should be 16 feet, in order to maximize the volume.

We have,

Volume = Length x Width x Height

Since we want to maximize the volume, we need to make the length, width, and height of the room as equal as possible.

So,

Length = Width

Now we can substitute the given values into the formula and solve for the dimensions of the room:

Volume = Length x Width x Height

Volume = (Length)² x Height

Volume = (Length)² x 16 (since the height of the room is 16 feet)

Volume = 16 (Length)²

The length of the house is 100 feet, and we have set the length and width of the room to be equal, so:

Length + Width = 100

Length + Length = 100

2 Length = 100

Length = 50

Therefore,

The length and width of the room should be 50 feet, and the height should be 16 feet, in order to maximize the volume.

Answer:

Step-by-step explanation:

Set X is 3, and all number greater than 3 up, but not including, 5.

Set Y is all numbers from 4 to 9, but not including 4 or 9.

The union of the sets is all numbers from 3 up to 9, including 3 but not including 9.
A ∪ B = [3, 9)

Ans: 2/3

Step-by-step explanation:

Formula : \(m = \frac{y2 - y1}{x2- x1}\)  (Then replace the number in )

= 3- (-1) / 4 - (-2) = 4 / 6 = 2 / 3

Step-by-step explanation:

the slope is always the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.

so, when going from (-2, -1) to (4, 3)

x changes by +6 (from -2 to 4).

y changes by +4 (from -1 to 3).

therefore, the slope is

+4/+6 = 4/6 = 2/3

To estimate the intercept of the trend line in the third quarter, we need to substitute the values into the equation. Here, t represents the quarter number.

The variable d is a dummy variable that takes the value 1 in the second quarter and 0 otherwise. Therefore, in the third quarter, d will be 0.

The results of the estimation are not provided, so we cannot directly determine the values of a, b, or c. However, we can determine the intercept by plugging in the values of the coefficients based on the given options.

If X is a set and A is a o-algebra of subsets of X, then the following is true: Ac {0, X} C 2X.

What is an algebra of subsets?

An algebra of subsets is a non-empty collection A of subsets of a set X that is closed under the set-theoretic operations of finite unions and complements. Also, an algebra of subsets of a set X is sometimes referred to as an algebra of sets on X.

It is necessary for an algebra of subsets to contain the empty set. It follows that it should be closed under complementation (if A belongs to A, then the complement of A belongs to A).

What is an o-algebra of subsets?An o-algebra of subsets (o stands for "orthogonal") is a collection A of subsets of a set X that is closed under set-theoretic operations, including complements, finite unions, and infinite intersections. An o-algebra of subsets is also known as a sigma algebra.Let's see the given options.a. 2% CAC{0, X}. --> Incorrect because there is no notion of 2%.b. Ac {0, X} C 2X --> Correct because we know that an o-algebra is closed under complements, hence Ac belongs to A and {0, X} C 2X is true.Therefore, the correct answer is option (b).

Answer:

86 degrees

Step-by-step explanation:

Alrighty, a simple 180-degree triangle, we can see that the two angles add up to 86, so what would make our angle G1 94 since 180-86 = 94, but we are tasked with finding the other side of that angle, let's call it G2, what should we do?

Since this is a flat 180-degree line, we do it again!

180-94 = 86 degrees

And there ya have it

Though, if you need the technical side, it's because a whole of a triangle is 180 degrees

Given that angles F is 58 and E is 28, we add those two up to find angle EGF. How to find EGF you ask? Simple- 180 degrees (Because it's a triangle) minus 86 (Added angles of E and F), that would equal 94.

Now, we are tasked with finding TGF. We do not have TGF but we have EGF. Learning that, we see the line ET, indicating that we have found ourselves a 180-degree line. What do we do with this line? We use it to calculate TGF with EGF

Since EGF is 94, we take the 180 - 94 to equal 86, and that is how you find TGF

Answer:

101.32 gets rounded to 101.

Why this is your answer:

101 is your answer because...

1. As we can see in the question, it says, "What whole number". That means, we have to see in the decimals in the number "101.32".

2. We can see that In the number "101.32", there is 32 as the decimal number, first we should look at the "tenths" number. Which is 3.

3. As you know, anything 4 and below, stays as it's own number, and 5 and higher, goes to the next whole number. Here, we have 3 as the "Tenths". And according to that rule... You think, what should we do?

4. As we saw that rule, we know that 3 is smaller than 4. That easily means that , The number will get rounded to the whole number it was.
