Which expression represents "the sum of 3 and n?

Answer:

D. a = m + 30

Step-by-step explanation:

It's not A, because that would be dividing Malik's score in half to get Alexia's score.

B only works for the first line.

C is adding 10 to Malik's score, and the difference is greater than that...it's 30 points.

Solution :

In this case we have to use [tex]$\text{chi square test}$[/tex] for the goodness of fit.

Null hypothesis is : [tex]$H_0 :$[/tex] Data follows the given distribution

Alternate hypothesis is : [tex]$H_a:$[/tex] Data do not follow the given distribution

The level of significance, [tex]$\alpha = 0.05$[/tex]

The test statistics is given by :

Chi square = [tex]$\sum\frac{(O-E)^2}{E}$[/tex]

Here O is the observed frequencies

         E is the expected frequencies

So we have, N = number of the categories = 4

df = degrees o freedom = N - 1

                                        = 4 - 1 = 3

Critical value  = [tex]$7.814727764$[/tex]

Calculating the table for the test statistics are given as :

  Category      prop.     O        E       [tex]$\frac{(O-E)^2}{E}$[/tex]

   A                   0.2     14       20         1.80

   C                   0.3     28       30         0.13

   M                  0.1        6        10          1.60

  P                    0.4      52       40         3.60

Total                  1        100      100        7.13

The test statics = chi square  = [tex]$\sum\frac{(O-E)^2}{E}$[/tex] = 7.13

[tex]$X^2$[/tex] statistics = 7.13

P-value = 0.067767248

P -value > [tex]$\alpha = 0.05$[/tex]

Therefore, we do not reject the [tex]$\text{null hypothesis}$[/tex]. There is sufficient evidence to conclude that the data follows the given distribution. So there is sufficient evidence to conclude the given claim is true.

Answer:

13

Step-by-step explanation:

The Pythagorean theorem state

a^2 +b^2 = c^2  where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = c^2

25+144 = c^2

169 = c^2

Take the square root of each side

sqrt(169) = sqrt(c^2)

13 = c

Answer:

784

Step-by-step explanation:

First get the total area of the rectangle

40 * 20 = 800

Now get the triangle.

The base will be 20 - 16 = 4

The height will be 40 - 32 = 8

Your formula for area of a triangle is

A = height * (base/2)

A = 8 * (4/2)

A= 8 * 2

A = 16

Now substract the triangle from the total of the rectangle

800 - 16

Answer:

Triangle

Step-by-step explanation:

When you slice it in half, it becomes a triangle because the big equilateral triangle is turned into a right triangle.

Answer:

B

Step-by-step explanation:

Answer:

The Answer is gonna be B) -7b2 + 2b -8

Explanation :

= 3-b(7b+ 2) + 3b - (11 – b).

= -7b2 +

=7b2 - 2b +3b +b - 11 + 3

= 3- 7b2 - 2b + 3b- 11+ b

= 7b2 +2b - 8

Sorry I corrected my mistake and B was the right Answer :3

Answer:

y =74x

Step-by-step explanation:

A proportional relationship is represented by y = kx where x is the independent variable, or input, k is the constant of proportionality, and y is the dependent variable or output.

What do we do to the values in the row for x to get the values in the row of y?

It helps to have x = 1 in this table.

74 = (k)(1)

Step-by-step explanation:

yes

Line EB is a diameter which splits the circle in the middle so the arc of EB would be half the circle. The arc goes through B and continues to C making the arc longer than half the circle.

An arc that is longer than half a circle would be a major arc.

The answer is: Major Arc

Answer:

-15

Step-by-step explanation:

When m=3 and n=-4

So, put the values

7(3)+3(3)(-4)

-> -15

Answer:

-15

Step-by-step explanation:

= 7(3) + 3(3)(-4)

= 21 + 3(3×-4)

= 21 + 3(-12)

= 21 + -36

= 21-36

= -15
