C. x is an even number

Step-by-step explanation:

The open statement is x is an even number. The correct option is C.

A statement (as in mathematics) that contains at least one blank or unknown and that becomes true or false when the blank or unknown is filled in or a quantity is substituted for the unknown. The sentences "n + 5 = 3" and "it is divisible by 6" are both open sentences.

here te open statement is given as x is an even number because the statement says that there is an unknown number which is even in nature. So there is a blank for the number the number can be anything from all the even numbers.

Answer:

The ball is 3.86 meters from the wall when it stops rolling.

Step-by-step explanation:

Representation of the situation:

This situation can be represented by a right triangle:

The hypotenuse is the distance the ball traveled, of 6 meters.

The distance from the wall is the side opposite to the angle of 40º.

We have that:

Sine of an angle is the length of the opposite side divided by the hypotenuse. So, in this situation.

Sine of 40 degrees = Distance from the wall/6

Sine of 40 degrees is of 0.64278760968.

Distance = 6*0.64278760968 = 3.86.

The ball is 3.86 meters from the wall when it stops rolling.

answer:

12.5%

explain:

16 seats= 6.25% for each seat

4/16=25%

the chances of it happening again is 12.5%

The probability that you are assigned to a desk in the front row exactly twice is 12.5%.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that the desks in a classroom are organized into four rows of four columns. each day the teacher randomly assigns you to a desk. you may be assigned to the same desk more than once. over the course of 5 days,

The probability will be calculated as,

16 seats = 6.25% for each seat

4/16=25%

The chances of it happening again are 12.5%

Therefore, the probability that you are assigned to a desk in the front row exactly twice is 12.5%.

Answer:

x=2 and y=-6 aka. (2,-6) which is the point of intersection

Step-by-step explanation:

Use elimination to cancel out y by adding the equations:

5x=10

x=2

Plug x=2 into one of the equations and find y:

2(5)+2y=-2

10+2y=-2

2y=-12

y=-6

Therefore, x=2 and y=-6

Answer:

14800

Step-by-step explanation:

Area of trapezoid = [tex]A=\frac{a+b}{2}h[/tex]

Using the formula above, our equation will look like this:

[tex]\frac{145 + 225}{2} * 80 = 14800[/tex]

145 + 225 = 370

370/2 = 185

Answer:

the answer is going to be b because u going to say In8=×

Answer:

b = 4 inches and h = 14 inches

Step-by-step explanation:

Given that,

The area of a triangle, A = 28 sq inches

Height is twice less than 4 times the base.

H = 4b-2, b is base

We know that,

The area of a triangle is given by :

[tex]A=\dfrac{1}{2}bh\\\\28=\dfrac{1}{2}\times b\times (4b-2)\\\\56=4b^2-2b\\\\28=2b^2-b\\\\b=4\ inches,-3.5\ inches[/tex]

Base = 4 inches

Height = 4(4)-2

= 14 inches

Hence, this is the required solution.

Answer:

Step-by-step explanation:

The steps required to solve the given equation is required.

First step: Identify a = 1, b = 3 and c = -4

Second step: [tex]x=\dfrac{-3\pm \sqrt{3^2-4\times 1\left(-4\right)}}{2\times1}[/tex]

Last step: x = 1 and x = -4

The given equation is

[tex]x^2+3x-4=0[/tex]

Comparing with the general quadratic equation [tex]ax^2+bx+c=0[/tex] we have

a = 1

b = 3

c = -4

Applying the formula

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\Rightarrow x=\dfrac{-3\pm \sqrt{3^2-4\times 1\left(-4\right)}}{2\times1}\\\Rightarrow x=1\ \text{and}\ -4[/tex]

Answer:

65 r 9

Step-by-step explanation:

First we see what 7 divided by 11 is, we know that it is 0 so we put it in the top as our first number then we subtract 0 from 7 which is 7, then we bring down the 2 to make our next number 72, now we see if 11 can go into 72 and we know that it can by 6, we put our six on the top and then multiply it by 11 to get 66, we subtract our 66 from 72 to get 6, we bring down the 4 to make 64 and divide it by 11 to get 5 which we put on the top, then multiply 5 by 11 to get 55, subtract 55 by 64 to get 9 and because now there's no more numbers in the sum, 9 is our remainder.

Answer:

Step-by-step explanation:

This is a quadratic equation.  We'll find the discriminant, but must first rewrite this equation in standard form:

5w2 – 2w + 4 = -4 + 4, or 5w^2 - 2w + 4 = 0

The coefficients of the w terms are {5, -2, 4}

and so the discriminant b^2 - 4ac  is  4 - 4(5)(20) = -396

Because the discriminant is negative, we know that there will be two unequal, complex solutions.

Answer:

For repeating decimal numbers like the decimals given in the data, you need to place a 9 in the denominator. For example, if the repeating decimal is 0.777777777..., the fraction should be 7/9 or if the repeating decimal is 0.567567567567..., the fraction should be 567/999. (The number of 9's depends on the amount of numbers being repeated.) In this case, because the repeating decimal is 0.88888888..., the fraction should be 8/9 and because the repeating decimal is 0.45454545..., the fraction should be 45/99 or 5/11.

[tex]P(X <= 10.9)=?[/tex]

The z-value is determined using the central boundary theorem

Answer:

B. y = 5x²

Step-by-step explanation:

As you can see, g(x) is a proper parabola, so it must be some variation of y = x².

Because the vertex of the parabola remains at (0, 0), know that there is no translation, so all we need to account for is the scale.

In the graph we can see that where x is equal to 1, y is equal to 5.  On a normal parabola that would instead be (1, 1), so we know that the y axis is scaled by a factor of five.  With that we can say that y = 5x².
