Answer:$ 16.50

Step-by-step explanation:If you are adding, you do

$8.50+

8.00

------------

16.50

0 plus 0 is nothing.

5 plus 0 is 5.

8 plus 8 is 16.

Your answer is now "16.50" .

After solving the system of equation we will get

x = 5y/2 +1  

y = 2/5- 2x/5

First equation is written

−2x+5y=−2

Subtract 5y from both sides.

−2x =−2−5y

The equation is in standard form.

−2x=−5y−2

Divide both sides by −2.

-2x/-2 = -5y-2/ -2

Dividing by −2 undoes the multiplication by −2.

x= −5y-2/-2

​Divide  −2−5y  by −2.

so

x= 5y/2 + 1

Now the second equation is

4x−10y=4

Add 4x to both sides

-10y = 4-4x

The equation is in standard form.

Divide both sides by 10

-10y/10= 4-4x/10

Dividing by 10 undoes the multiplication by 10.

y= 4-4x/10

Divide 4-4x by 10.

so

y= 2/5- 2x/5

Answer:

Step-by-step explanation:

Step 1: You have the slope so its already y=-4x+b. So you need to find the y intercept.

To find the y intercept, you need to plug the coordinates in. So 2=-4(-3)+b. Then you solve the equation from there.

1.46% probability that fewer than 700 children received their vaccine.

What is probability?

The proportion of favorable cases to all possible cases is used to determine how likely an event is to occur.

Here, we have

95% of children have received their DTaP vaccine p = 0.95

Sample of 750, n = 750

For the approximation, the mean and the standard deviation are given by:

u = np = 750×0.95 = 712.5

σ = [tex]\sqrt{np(1-p)}[/tex]

σ = [tex]\sqrt{750(0.95)(0.05)}[/tex]

σ = 5.97

Using continuity correction, the probability that fewer than 700 children received their vaccine is P(X < 700 - 0.5) = P(X < 699.5), which is the p-value of Z when X = 669.5.

Z = X-u/σ

Z = 669.5 - 712.5/5.97

Z = - 2.18

The p-value of Z = - 2.18 is 0.0146.

Hence, 1.46% probability that fewer than 700 children received their vaccine.

Answer: -1

Step-by-step explanation: Plug 1 in as x. You get h(1)=-3(1)+2. If you solve this, it is h(1)=-3+2, or h(1)=-1

Answer:

[tex] \sf \: h(1) = - 1[/tex]

Step-by-step explanation:

Given equation,

→ h(x) = -3x + 2

Now the value of h(1) will be,

→ h(x) = -3x + 2

→ h(1) = -3(1) + 2

→ h(1) = -3 + 2

→ [ h(1) = -1 ]

Hence, the value of h(1) is -1.

a) The average cost of the promotion is $0.01 per tire.

b) The probability that Greer will refund more than $25 for a tire is 0.9

According to the Question:

Greer Tire Company has:

Lifetime mileage = 33500

Standard Deviation = 3500 miles

a)

Meal lifetime mileage : $33,500

Standard deviation of mileage $3,500

Observed miles 30,000 miles

100 miles failed $1.00

Hence :

The average cost of the promotion:

= (33,500 – 30,000) / 3500

= 3500 /3500

= 1

Therefore,

Cost of production

100 miles = $1.00

= 1 * 1 / 100

= $0.01 per tire

b)

 P (z < 25000 -33500/ 3500

= P (z < -8500/ 3500)

= z < -2.4

Hence:

= 1 - 0.1

= 0.9

Step-by-step explanation:

there are four of them and four spaces, so you would do 4x4. 4x4= 16

The linear function that represents the graph of that has the points on the table is: A. .f(x) = 32(3x - 1).

If a point is on a graph of a linear function, its coordinates will make the equation of the linear function true, if plugged into the equation.

Given the table that represents some of the points that are on a linear function graph, use one point, (1, 64), to check which of the functions represents the table.

Substitute x = 1 and .f(x) = 64 into each of the functions given to see which is true:

.f(x) = 32(3x - 1)

64 = 32(3(1) - 1)

64 = 32(3 - 1)

64 = 32(2)

64 = 64 [true]

.f(x) = -32(x - 3)

64 = -32(1 - 3)

64 = 64 [true], however, if we use another set of values, say (5, 448), this function will not be true.

.f(x) = -2(32x - 3)

6 = -2(32(1) - 3)

6 = -2(29)

64 = -58 [not true]

.f(x) = 16(2x - 1)

64 = 16(2(1) - 1)

64 = 16(1)

64 = 16 [not true]

Therefore, the function that represents the table is: A. .f(x) = 32(3x - 1).

Its means that the addition of natural numbers obeys the closure property.

In mathematics, the closure property is a property that states that if a set is combined with all its limit points, then the combined set is also a limit point. The closure property applies to sets of real numbers, vectors, and matrices. It states that the closure of a set is itself, i.e., the set is closed under the given operation. The phrase "closed under addition" means that when two natural numbers are added together, the result is also a natural number. In other words, natural numbers are part of a closed system concerning addition; the addition operation always produces another natural number.

Step-by-step explanation:

There are no like terms to 5, so it stays the same

y = -5x – 13 equation is the equation of a line that passes through (- 10 3 and is perpendicular to Y 5x 7 with slope

The equation of a line is y = mx + b, where m is the slope and b is the y-intercept. To find the equation of a line that passes through (-10, 3) and is perpendicular to y = 5x + 7, we need to find m, the slope of the line.

We can find the slope of the line by using the point-slope form of a line, which is y - y1 = m(x - x1). In this equation, m is the slope, (x1, y1) is a given point on the line, and (x, y) are the coordinates of any point on the line.

Plugging in the given point of (-10, 3) and the line y = 5x + 7 into this equation, we get:

3 - 3 = m(-10 - -10)

The left side of this equation is 0, so the right side must also be 0. That means that m = 0.

Now that we have the slope of the line, we can plug it into the equation of a line, y = mx + b, to get the equation of the line:

y = 0x + b

Next, we need to find the y-intercept, b. To do this, we can use the given point (-10, 3). Plugging this in to the equation above, we get:

3 = 0x + b

Simplifying, we get:

b = 3

Now that we have the slope and y-intercept, we can write the equation of the line in slope-intercept form:

y = 0x + 3

Finally, we can simplify this equation to get the final answer:

y = -5x – 13

It would cost $1804.86 to buy concrete for repavement of the driveway if 1 cubic yard of concrete costs $130 .

Given,

Width of driveway = 30 ft = [tex]\frac{30}{3}[/tex] = 10 yard

Length of driveway  = 50ft = [tex]\frac{50}{3}[/tex] = 16.667 yard

As the driveway is repaved by pouring concrete then it's height will increase

Height of driveway = 3 inch = [tex]\frac{3}{36}[/tex] = 0.0833 yard

Volume of driveway = length x breadth x height

Volume of driveway = 10 x 16.667 x 0.0833

Volume of driveway = 13.8836 cubic yard

Cost of 1 cubic yard of concrete = $130.00

The required length of one of the longest sides is 29 in the given pentagon.

The pentagon has 3 sides of length (2x - 1) and 2 sides of length (x + 5) and the perimeter of the pentagon is 127.

We know that the perimeter of the pentagon is the total length of all its sides, so we can set up the following equation:

3(2x - 1) + 2(x + 5) = 127

Apply the distributive property of multiplication,

6x - 3 + 2x + 10 = 127

Combine the likewise terms of the equation,

8x + 7 = 127

Finally, we can solve the equation by subtracting 7 from both sides and dividing both sides by 8:

8x = 120

x = 15

Therefore, the length of one of the longest sides is (2 × 15 - 1) = 29.
