Answer:

17.728

Step-by-step explanation:

Answer:

3.4

Decrease ; 3.375

Step-by-step explanation:

Mean = Σfx / Σf

Σfx = (1 * 2) + (2 * 2) + (3 * 3) + (4 * 9) = 51

Σf = 1 + 2 + 3 + 9 = 15

Mean = 51 / 15 = 3.4

If 1 more dot is added to the 3rd column:

Σfx = (1 * 2) + (2 * 2) + (3 * 4) + (4 * 9) = 54

Σf = 1 + 2 + 4 + 9 = 16

Mean = 54 / 16 = 3.375

Answer:

B. 9/20[tex]\pi[/tex]

Step-by-step explanation:

the circumference is 2[tex]\pi[/tex]r. Since the radius is one, that would be 2[tex]\pi[/tex].

81/360=0.225, or 22.5% of the circumference.  22.5% of 2[tex]\pi[/tex] is 0.45[tex]\pi[/tex].  0.45=9/20, so the answer is B.

CHECK: 2[tex]\pi[/tex] = 6.283

6.283x0.225=0.14137, or 9/20[tex]\pi[/tex]

Answer:

[tex]-3 + 2x[/tex]

Step-by-step explanation:

Given

[tex]2x - 3[/tex]

Required

An equivalent expression

The expression can be rewritten as:

[tex]-3 + 2x[/tex] ---- commutative property of addition

[tex]2x - 3[/tex] and [tex]-3 + 2x[/tex] are equivalent

An expression that has two terms that is equivalent to 2x – 3 is - 3 + 2x

Given:

2x - 3

There are just two terms in the expression

The two terms can be written interchangeably to form a new expression equivalent to the same

-3 + 2x (This is based on the cummutative property of addition)

The new expression equivalent to 2x - 3 is -3 + 2x (minus 3 plus 2x)

Answer:

33046 students

Step-by-step explanation:

Find how many students attend the college by dividing 24,950 by 0.755

24,950 / 0.755

= 33046.36

Round down, since the answer has to be a whole number:

33046.36

= 33046

So, approximately 33046 students attend the college

Answer:

Let point's possessed by school A = x

and point possessed by School B = y

And the statement given Regarding the school are :

School X has eight more points than School Y. School X has three times as many points as School Y .

Writing these statements in terms of equation

1.   x = y + 8

2.  x = 3 y

Substituting the value of x in y, we get

3 y = y + 8

Taking variable on left side of equation

3 y - y = 8

2 y= 8

y =  

As , x= y + 8 gives x = 4 + 8 = 12

Point possessed by School A = 12 points

Points possessed by school B =  4 points

Answer:

900 sample size

Step-by-step explanation:

To determine the sample size for a proportion, the margin of error formula is used to determine this:

[tex]E=Z_{\frac{\alpha}{2} }*\sqrt{\frac{\hat p \hat q}{{n} }[/tex]

[tex]n=\hat p \hat q*(\frac{Z_{\frac{\alpha}{2} }}{E} )^2[/tex]

Where p is the proportion, E is the margin of error, n is the sample size, q = 1 - p, [tex]Z_\frac{\alpha }{2}[/tex] is the z score.

Since the proportion is not known, the sample size needed to guarantee the confidence interval and error is at p = 0.5 and q = 1 - p = 1 - 0.5 = 0.5

E = 5% = 0.05, [tex]Z_\frac{\alpha }{2}[/tex] = 3. Hence:

[tex]n=0.5*0.5*(\frac{3}{0.05} )^2\\\\n = 900[/tex]

Answer:

y=7/4x+2

Step-by-step explanation:

The linear equation in the slope-intercept form will be y = (7/4)x + 13/4.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

y − 5 = 7/4(x − 1)

Convert the equation into a slope-intercept form. Then we have

y − 5 = 7/4(x − 1)

y − 5 = (7/4)x − (7/4)

y = (7/4)x − (7/4) + 5

y = (7/4)x + 13/4

The linear equation in the slope-intercept form will be y = (7/4)x + 13/4.
