The number of cans required to paint an area of 2000 square units is equal to 5 cans.

As given in the question,

Total area to be painted is equal to 2000 square units.

Area covered by one can of paint is equal to 400 square units

400 square units = 1 can of paint

⇒ 1 square units = ( 1 / 400 ) cans of paint

⇒ 2000 square units =  ( 2000 / 400 ) cans of paint

⇒ 2000 square units = 5 cans of paint

Therefore, the number of cans required to paint an area of 2000 square units using given can is equal to 5 cans.

The above question is incomplete, the complete question is:

How many cans of paint are needed to cover an area of 2000 square units if one can of paint covers in area 400 square units?

Answer:

x=7

Step-by-step explanation:

y=mx

5.5=m×11

5.5÷11=m

m=1/2

y=mx

3.5=1/2×x

3.5÷1/2=x

x=7

Answer:

x =7

Step-by-step explanation:

The direct variation equation is y = kx, where k is the constant of proportionality.

If y = 5.5 when x = 11, we can write 5.5 = 11k, which, when solved for k, yields k = 0.5.  

Then the direct variation equation in this case is y = 0.5x.

If y = 3.5, what is x?  y = 0.5x becomes 3.5 = 0.5x, yielding x = 7

Answer:

  A.  f(0) = 4

  B.  f(6) = 8

Step-by-step explanation:

When evaluating a piecewise function, the fist step is to determine the applicable domain. Then the function defined for that domain is the one that is used for the evaluation.

x = 0 is in the domain x < 5, so the applicable function is f(x) = x+4.

  f(0) = 0 +4 = 4

__

x = 6 is in the domain 5 ≤ x < 7, so the applicable function is f(x) = 8.

  f(6) = 8

The following are the two most typical instances of this: Equilateral triangles are used to make truss bridges, which are built on both sides.

Congruence :

If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create an identical appearance. They are in alignment with one another when moved. A term used to describe an object and its mirror counterpart is congruence. If two things or shapes superimpose on one another, they are said to be congruent. They are identical in terms of size and shape. Line segments having the same length and angles with the same measure are congruent in the context of geometric figures.

the correct answer is B. ŷ = -157 + 40.2x; yes, because the r-value is high. The regression line would be a good predictor of other data points because of the strong linear relationship between x and y, as indicated by the high r-value.

To determine the line of regression, we can use linear regression analysis. The regression line is a straight line that best represents the relationship between the two variables. It is determined by minimizing the sum of squared deviations between the observed values and the predicted values of the response variable.

Using a calculator or statistical software, we can find that the regression line for this data set is:

ŷ = -22.2933 + 32.0472x

The r-value (correlation coefficient) for this data set is 0.969, which is relatively high. This indicates a strong positive linear relationship between x and y.

The expression "3' - '2' + 'm' / 'n'" is invalid because it combines character literals and arithmetic operations. The expression "3' - '2' + 'm' / 'n'" is not valid in most programming languages.

It attempts to mix character literals ('3', '2', 'm', 'n') with arithmetic operations (-, +, /), which is not meaningful. In programming languages, characters are typically represented using character literals enclosed in single quotes.

While arithmetic operations are performed on numerical values. The expression should be revised to ensure that the operations are performed on numerical values rather than character literals.

For example, if 'n' and 'm' represent numerical values, the expression could be written as "3 - 2 + m / n" to perform arithmetic operations correctly.

The equation \((sin(x)cos(x))^2 = sin(2x)\) is verified to be an identity.

Simplify LHS and RHS?

To verify whether the equation \((sin(x)cos(x))^2 = sin(2x)\) is an identity, we can simplify both sides of the equation and see if they are equivalent.

Starting with the left side of the equation:

\((sin(x)cos(x))^2 = (sin(x))^2(cos(x))^2\)

Now, we can use the trigonometric identity \(sin(2x) = 2sin(x)cos(x)\) to rewrite the right side of the equation:

\(sin(2x) = 2sin(x)cos(x)\)

Substituting this into the equation, we have:

\((sin(x))^2(cos(x))^2 = (2sin(x)cos(x))\)

Next, we can simplify the left side of the equation:

\((sin(x))^2(cos(x))^2 = (sin(x))^2(cos(x))^2\)

Since both sides of the equation are identical, we can conclude that the given equation is indeed an identity:

\((sin(x)cos(x))^2 = sin(2x)\)

Hence, the equation \((sin(x)cos(x))^2 = sin(2x)\) is verified to be an identity.

Step-by-step explanation:

Train 1 speed be 'u'

Train 2 speed be 'v'

And v=2u

Speed=distance/time

Trains going in opposite directions

The expected value of the minimum of two independent uniformly distributed random variables x and y between 0 and 1 is 1/4. It is found by integrating over the two possible triangles and averaging the results.

Let M be the minimum of x and y. We can find the expected value of M by integrating over all possible values of x and y:

E(M) = ∫∫ min(x,y) f(x,y) dxdy

where f(x,y) is the joint probability density function of x and y.

Since x and y are independent and uniformly distributed between 0 and 1, their joint probability density function is:

f(x,y) = 1, for 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1

and zero otherwise.

Therefore, we have:

E(M) = ∫∫ min(x,y) f(x,y) dxdy

= ∫∫ min(x,y) dxdy, for 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1

To evaluate this integral, we can split the region of integration into two parts: the triangle where x ≤ y and the triangle where x ≥ y. In each part, we can express the minimum of x and y as a function of one of the variables:

For x ≤ y:

E(M) = ∫∫ min(x,y) dxdy = ∫0^1 ∫x^1 x dy dx

= ∫0^1 (x - x^2/2) dx = 1/3

For x ≥ y:

E(M) = ∫∫ min(x,y) dxdy = ∫0^1 ∫0^y y dx dy

= ∫0^1 y^2/2 dy = 1/6

Therefore, the expected value of the minimum of x and y is:

E(M) = 1/3 * (area of triangle where x ≤ y) + 1/6 * (area of triangle where x ≥ y)

= 1/3 * 1/2 + 1/6 * 1/2

= 1/4

Hence, the expected value of the minimum of x and y is 1/4.

Answer:

$40y - $3g

Step-by-step explanation:

it wouldn't be c because the 3 and 40 are on the wrong side. and it wouldn't be a because the y and g are on the wrong number. you should realise that the variables y and g need to go to the corresponding amount and $40 is how much she get by mowing lawns (y) and $3 is how much gasoline costs to take away from her total amount. so its now between b and d. it is d because you are subtracting 3 from 40 because that how much she spent and it takes away from her total.

Option D : $40y − $3g  is correct.

We have the following information about Alicia -

For every yard she mows, she earns $40

She spends part of this money on gasoline which costs $3

We have to find expression for the amount of money that Alicia earns in a day.

An equation of the form ax + by + c=0, where a, b are the coefficients of x and y and are non -zero and all a, b, and c are real in nature.

Let the amount of money she earns in a day = x

Number of yards she mows in a day = y

Money earned on mowing ' y ' yards in a day = $40 y

Number of gallons of gasoline she buys = g

Amount spent in gasoline in a day = $3 g

Total money earned  = Money earned - money spent on gasoline

x = $40y - $3g

Hence, Option D is correct

The probability that the cards left are all spades when drawing cards at random and without replacement until only cards of one suit are left is given by P(all spades) = 13! / 52!.

To find the probability that the cards left are all spades when drawing cards at random and without replacement until only cards of one suit are left, we need to consider the number of spades in the deck and the total number of possible outcomes. In a standard deck of 52 cards, there are 13 spades (assuming we're considering a deck with the usual 4 suits). When we start drawing cards, the number of spades in the deck will decrease with each draw.

The total number of possible outcomes is the number of ways we can arrange the 52 cards in different orders. This can be calculated using the concept of permutations. The total number of possible outcomes is denoted by 52! To calculate the probability, we need to determine the number of favorable outcomes (where all the cards left are spades) and divide it by the total number of possible outcomes.

Since there are 13 spades in the deck, and we continue drawing cards until only cards of one suit are left, the number of favorable outcomes is the number of ways to arrange these 13 spades among themselves. This can be calculated as 13!. Therefore, the probability that the cards left are all spades is given by:

P(all spades) = favorable outcomes / total outcomes

= 13! / 52!
