Multiply and simplify

Answer:

Yes

Step-by-step explanation:

It can be rewritten as y = -x + 1.

The slope is -1 and the y-intercept is (0,1)

Final answer:

The equation y=1-x is indeed a linear equation, fitting the general form y = a + bx with a slope of -1 and y-intercept of 1.

Explanation:

Yes, y=1-x is a linear equation. In general, a linear equation can be written in the form y = a + bx, where a is the y-intercept and b is the slope. In this case, the equation y=1-x can be rewritten as y = (-1)x + 1, which clearly fits the form of a linear equation with a slope of -1 and a y-intercept of 1.

The graph of a linear equation is a straight line, and the equation y=1-x represents a straight line with a downward slope. Unlike nonlinear equations, such as y=xb where b is a power, linear equations represent a direct proportionality between y and x.

Answer:

E

Step-by-step explanation:

map scale: actual scale

= 1 inch: 3 feet

Area scale

= (1 in)²: (3 ft)²

= 1 in²: 9 ft²

This means that 1 in² of the drawing represents an actual area of 9 ft².

Area of garden in the drawing

= 5(3.5)

= 17.5 in²

Area of actual garden

= 17.5 ×9

= 157.5 ft²

Thus, the answer is E.

Answer:

Choice 2

Step-by-step explanation:

The following distribution is not a probability distribution because the probability values do not add to 1.

If it were a probability distribution, the sum of all the probability values would be equal to 1.

The sum of the probability values is 0.16 + 0.15 + 0.42 + 0.13 + 0.31,

which is equal to 1.17.

Since the sum is greater than 1, it violates the requirement for a probability distribution.

Hence, the probability values do not add to 1.

Answer:

-b/2a

Step-by-step explanation:

Answer:

Convert fractions, decimals, and percents to the same form to compare the values. Convert Percent to Decimal or Fraction. Convert Decimal to Percent or Fraction. Convert Fraction to Decimal or Percent. Then figure out which is greater or lesser. Use this information to write a set of numbers or quantities in order from least to greatest or from greatest to least.

Step-by-step explanation:

Ordering numbers mean plan of numbers either from little to enormous or from huge to little. At the point when the numbers are orchestrated in an expanding order, it is known as Ascending Order, and when the numbers are organized in a diminishing order, and afterward they are known as Descending Order. For ascending, check the most modest number from the given rundown and spot it first and afterward put the numbers as indicated by the expanding order. For descending check the greatest number from the given rundown and spot it first and afterward put the numbers as per the diminishing order.

A percentage is a part of an entire communicated as a number somewhere in the range of 0 and 100 instead of as a portion. All of something is 100 percent, half of it is 50%, none of something is zero percent.

A decimal is a part written in an extraordinary structure. Rather than composing 1/2, for instance, you can communicate the division as the decimal 0.5, where the zero is during the ones spot and the five is in the tenths spot.

A fraction just discloses to us what number of parts of an entire we have. You can perceive a fraction by the slice that is composed between the two numbers. We have a top number, the numerator, and a base number, the denominator. For instance, 1/2 is a fraction. You can compose it with an inclined slice like we have or you can compose the 1 on the 2 with the slice between the two numbers. The 1 is the numerator, and the 2 is the denominator.

Answer:

$21888

Step-by-step explanation:

96*48=4608

4608*$4.75=21888

The cost to do the resurfacing of the playground can be found to be $21, 888.

To find the cost of resurfacing the playground, you need to calculate the total area of the playground and then multiply it by the cost per square foot.

The playground is 96 feet long and 48 feet wide, so its area is:

Area = Length × Width

Area = 96 ft × 48 ft

Area = 4,608 square feet

Multiply the area by the cost per square foot:

Resurfacing Cost = Area × Cost per square foot

Resurfacing Cost = 4,608 sq ft × $4.75/sq ft

Now, calculate the resurfacing cost:

Resurfacing Cost = $ 21,888

Answer:

Angle 4 is 144.

Step-by-step explanation:

Applying the definition of vertical angles, the measure of angle 4 is: 144°.

Vertical angles are a pair of angles that lie directly opposite each other and are equal in measure to each other.

m∠1 + m∠2 = 180° (linear pair)

Substitute

3x + 12x = 180

15x = 180

x = 12

∠4 and ∠2 are vertical angles, therefore:

m∠4 = m∠2 = 12x

Plug in the value of x

m∠4 = 12(12)

m∠4 = 144°

Therefore, applying the definition of vertical angles, the measure of angle 4 is: 144°.

To calculate the slope of a line we require any two points along the line.

Explanation:

suppose two points are given that is (x1,y1) (x2, y2) . The equation of a line is  y-y1=m(x-x1) , where m is referred to as the slope of the line .

To find m,

m= y2-y1/x2-x1 . Hence this way of finding slope is known as point- slope form. Another form is there known as slope- intercept form

y=mx+c.

But to find a slope , minimum amount of information that we require is points along the line.

Final answer:

To calculate the slope of a line, only two points on the line are needed. Slope is computed as the difference in y-coordinates divided by the difference in x-coordinates of these points.

Explanation:

To calculate the slope of a line, the minimum amount of information needed is any two points along the line. The slope is the rate of change between two points on a line and can be calculated using the formula slope (m) = (Y₂ - Y₁) / (X₂ - X₁), where Y₂ and Y₁ are the y-coordinates and X₂ and X₁ are the x-coordinates of the two points. It is not necessary to know the length of the line, the endpoints specifically, or the x and y intercepts separately.

The slope-intercept form of a linear equation, y = mx + b, shows that m is the slope and b is the y-intercept. Here, the y-intercept is simply the point where the line crosses the y-axis, but it is not required for calculating the slope when you have two points on the line.

We have been given that a z-score table and corresponding probability to each z-score. We are asked to find the probability of a getting a z-score less than or equal to 0.42 that is [tex]P(z\leq0.42)[/tex].

z-score                               Probability

0.00                                    0.5000

0.22                                    0.5871

0.32                                     0.6255

0.64                                     0.7389

0.84                                     0.7995

1.00                                     0.8413

Upon looking at our given table, we can see that the probability corresponding to z-score of 0.42 is 0.6628.

[tex]P(z\leq0.42)=0.6628[/tex]

Now, we will convert [tex]0.6628[/tex] into percent as:

Answer:

36

Step-by-step explanation:

9 times 4

The perimeter of a square is calculated by 4 times the length of one side. For a square plastic tarp with each side being 9 meters, the perimeter would be 36 meters.

The perimeter of a square can be calculated by using the formula: 4 x side length. In this case, the length of the side of the tarp is 9 meters. Therefore, to find the perimeter, you would multiply 4 (the number of sides in a square) by 9 (the lengths of one side). That calculation would look like this: 4 x 9 = 36 meters. So, the perimeter of the square plastic tarp is 36 meters.

Move the decimal back to its point of origin

To multiply a number by a power of 10, you move the decimal point to the right by the number of zeros in the power of 10.

When multiplying a number by a power of 10, you can count the number of zeros in the power of 10 and move the decimal point that same number of places to the right.

In the case of multiplying 0.008 by 10, the power of 10 is 1, so you would move the decimal point one place to the right, resulting in 0.08.

Therefore, you multiply 0.008 by 10 to get 0.08.
