Which of the following is a monomial?

Answer:

45.7 meters

Step-by-step explanation:

15 = 6 + 7y

9 = 7y

y = 1.3

The two lengths are still the same, so you can set the two parts equal to the whole. Now that you have y you can substitute it in and add all the sides together.

3y + 7y + 3y + 6y + 6 +15 = P

3(1.3) + 7(1.3) + 3(1.3) + 6(1.3) + 6 + 15 = P

P = 45.7 meters

Step-by-step explanation:

The following shape is being reflected across the y-axis.

To confirm this, we can check the coordinates.

When something is reflected across the y-axis, its points' y-coordinate don't change. Upon evaluation of the given transformation, we can see that the y-coordinate does not change for any point.

Now, we check the x-coordinate. The x-coordinate MUST be the opposite of the original x-coordinate...

-2 --> 2

-4 --> 4

0 --> 0

-4 --> 4

-2 --> 2

All of the x-coordinates are opposites, and the y-coordinates remained the same, therefore this figure is being reflected across the y-axis.

Answer:

Step-by-step explanation:

Split the shape into two rectangles as shown in the attachment.

Rectangle I

length = 23 ft

Width = 9 ft

Area I = length * width

          = 23*9

          = 207 ft²

Rectangle II:

length = 13 ft

Width = 26 -9 = 17 ft

Area II = 13 * 17

            = 221 ft²

Area of the entire polygon = 207 + 221

                                              = 428 ft²

Answer:

The probability of testing positive for one is 0.20.

The probability of testing negative for one sample is (1-0.2)=0.8.

We only save time when all five are negative, which has a probability of 0.8^5=0.32768.

This means that the expected number of tests is

combined sample tests negative = 1 with probability 0.32768

combined sample tests positive = 1+5 retests = 6 with probability 0.67232

Expected number of tests

=Σ nipi / n

=(1*0.32768+6*0.67232)/5 [divide by 5 because we tested 5 samples]

= 0.87232 < 1

So yes, there is a saving.

Note: In practice, all medical tests are not absolute, i.e. they give false-positives(α) and false-negatives (β). The ratios 1-α and 1-β are respectively measures of specificity and sensitivity.

These two parameters complicate the simplistic evaluation above.

Step-by-step explanation:

multyply 2 x 2.91

the 2 folders are 5.82

Answer:

B

Step-by-step explanation:

if you cross-multiply the proportion in answer B you will get:

3x = 2(2.91)

3x = 5.82

x = 5.82÷3

x = 1.94

1.94 is the cost for 2 folders if 3 cost $2.91

Answer:

Step-by-step explanation:

Solution:

Note that:

Substitute the value of y into the equation to find x.

Substitute the value of x into any equation to obtain the value of y.

Putting the values in (x,y) form.

Answer:

Slope = 2

Y-intercept = -4

Step-by-step explanation:

The slope of a function is found by finding the change in the y-values and dividing it in the change in x-values.

The change in y-values is 2 because that is the difference between each given data point. The change in x-values is 1 for the same reason.

The slope would be 2/1 which is just 2.

The y-intercept can be found by setting up the function in slope-intercept form (y=mx+b) and using the given data to solve for b. The point I chose to do this with was (2,0)

y=mx+b

y=2x+b

0=(2*2)+b

0=4+b

b=-4

So the slope is 2 and the y-intercept is -4.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

We are given four number inequalities:

30 > 10

30 < 10

10 > 30

10 < 30

The first number sentence, "30 > 10", is true, since 30 is greater than 10.

The second number sentence, "30 < 10", is false, since 30 is not less than 10.

The third number sentence, "10 > 30", is false, since 10 is not greater than 30.

The fourth number sentence, "10 < 30", is true, since 10 is less than 30.

Therefore,

We would circle the first and fourth number sentences as true, and cross out the second and third number sentences as false.

The error that was made is found in; C: Step 3 and it can be corrected by Setting the width greater than.

When trying to construct a line tangent to circle O at a point say P, the steps are as follows;

Step 1; Draw a line from the center through P and beyond the circle.

Step 2; With the compass on P, draw an arc each side of P, creating Q and R.

Step 3; With the compass on Q, set its width to a setting greater than QP.

Step 4; Make an arc in a random location using Q as center with distance less than QR but greater than QP.

Step 5; Without changing the compass width, repeat step 4 for point R, creating point S.

Step 6; Draw a line through P and S.

Step 7; PS is the line tangent to circle O at point P

Looking at the steps and comparing to the question, it is clear that the error was in step 3 where they made the compass on Q equal to QP rather than greater than QP.

Answer:

NRs. 8925

Step-by-step explanation:

176 dollars = 100 pounds

132 dollars = ??? pounds

Using cross-multiplication, we get:

176 dollars x ??? pounds = 100 pounds x 132 dollars

??? pounds = (100 pounds x 132 dollars)/ 176 dollars

??? pounds = 75 pounds

Now, 1 pound = NRs. 119

So 75 pounds = NRs. ???

Using cross-multiplication again, we get:

1 pound x NRs. ??? = NRs. 119 x 75 pounds

NRs. ??? = (NRs. 119 x 75 pounds)/1 pound

NRs. ??? = NRs. 8925

So the answer is 8925 Nepali rupees

Answer:

gradient = -1

Step-by-step explanation:

identify the y intercept ( the point where it meet the y- axis ) which denoted by c in the formula y =mx + c

in the graph :the y- intercept is 5 (c)

take the coordinate of any point that passes through the line :- for example (2,3)

in (2,3), the value of x is 2

the value of y is 3

using the formula y = mx + c find m with is the gradient ( unknown )

y = mx + c

3 = m2 + 5

2m + 5 = 3

we sent + 5 to the right and it changes sign to become -5

2m = 3 -5

we substract -5 from 3

2×m = -2

we send 2 to the other side so that m can be alone, it change to become divide since it was multiply

m = -2 ÷ 2

m = -1

the gradient ( unknown ) = -1
