Answer:

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:

Number of pages Kayla read before dinner = [tex]9\frac{3}{8}[/tex] pages

Step-by-step explanation:

Given:

Total number of pages Kayla read on Friday = [tex]12\frac{1}{2}[/tex] = 25/2 pages

Number of pages Kayla read before dinner = [3/4][Total pages she read]

Find:

Number of pages Kayla read before dinner

Computation:

Number of pages Kayla read before dinner = [3/4][Total pages she read]

Number of pages Kayla read before dinner = [3/4][Number of pages Kayla read before dinner]

Number of pages Kayla read before dinner = [3/4][25/2]

Number of pages Kayla read before dinner = 75/8

Number of pages Kayla read before dinner = [tex]9\frac{3}{8}[/tex] pages

Answer:

The answer is "-9".

Step-by-step explanation:

[tex]\mu = 11.4\\\\\sigma = 0.2\\\\ x = 10.9\\\\[/tex]

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

The z-value is determined using the central boundary theorem

[tex]z = \frac{(x - \mu)}{\sigma}[/tex]

  [tex]= \frac{(10.9 - 11.4)}{0.2}\\\\ = -2.5[/tex]

Calculating the value for Aaron

[tex]\mu = 11.5\\\\ \sigma = 0.1\\\\ x = 10.6\\\\ P(X <= 10.6)=?[/tex]

When the z-value is calculated using Central Limit Theorem

[tex]z = \frac{(x - \mu)}{\sigma}[/tex]

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.

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%.

Step-by-step explanation:

First, find a common denominator

Let's use 60

Convert each fraction to a fraction with a denominator of 60

4/5 = 48/60

9/12 = 45/60

48/60 ≠ 45/60 so 4/5 ≠ 9/12

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.

Step-by-step explanation:

i had the same question on my test lol

Answer:

First multiply the first equation by 2

2(2x + y = 25)

You'll have

4x + 2y = 50

Rewrite both equations

4x + 2y = 50

3x - 2y= 20

Add from the first equation you'll get

7x = 70... X = 10

Substitute x in one of the equations:

3(10) - 2y = 20

30 - 2y = 20

-2y = -10

y = 5

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:

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]
