Answer:

Independence chi-square test

Step-by-step explanation:

The Chi-Square Test for independence is a type of statistical hypothesis test that is used to determine the existence of an association or relationship between nominal or categorical variables

The chi-square is given by the following formula;

[tex]\chi^2 = \XXL\sum \dfrac{\left (O_i - E_i \right)^2}{E_i}[/tex]

The number of participants = 80

The number that assigned a verdict of guilty = 27

The number that assigned a verdict of not guilty by reason of self defense = 49

The number that assigned a verdict of not guilty by reason of insanity = 4

Independence Chi Square test

The table of values is presented as follows;

Expected Value = (Row sum * Column Sum)/(Grand Total)

Expected Value for Guilty = 27 × 80/80 = 27

Expected Value for Self Defense = 49 × 80/80 = 49

Expected value for Insanity = 4 × 80/80 = 4

[tex]\begin{array}{ccc}Category&Observed&Expected\\Guilty&27&27\\SelfDe&49&49\\Insanity&4&4\end{array}[/tex]

Answer:

Multiply the circle's area by the cylinder's length to obtain the volume. If the length is, for instance, 10 inches, then compute as follows: 113 x 10 = 1,130 cubic inches.

Answer:

The first quartile is the median of the data points to the left of the median. The third quartile is the median of the data points to the right of the median. Step 4: Complete the five-number summary by finding the min and the max. The min is the smallest data point, which is 25.

Answer:

b > -15

Step-by-step explanation:

4b - 12 - 55 < 9b + 8

Combine terms.

4b - 67 < 9b + 8

Subtract 9b from both sides.

-5b - 67 < 8

Add 67 to both sides.

-5b < 75

Divide both sides by -5. When dividing by a negative, flip the sign.

b > -15.

Answer:

8!

Answer:

A.r>3

Step-by-step explanation:

r-1+1 >2+1 [adding '1'on both side]

we add 1 on both side to cancel the - 1 from L.H.S.

so, r > 3

Step-by-step explanation:

Answer:

V = (1/3)(121 in^2)(11 in) = 443.7 in^3

Step-by-step explanation:

If the side length of the square base is 11 cm, then the area of that base is (11 cm)^2, or 121 cm^2.  If the height of the pyramid is 11 cm (as you seem to indicate), then the volume of the squre pyramid is

V = (1/3)(121 in^2)(11 in) = 443.7 in^3

Answer:

If two planes intersect, then their intersection is a line.

Answer:

The real distance would be 16

Step-by-step explanation:

If the scale is 1/2, that means each distance on the map is half of what the real distance is. So 8 x 2 =16.

Answer:

80 miles.

Step-by-step explanation:

Since 1/2 an inch is 5 miles, that would mean one inch is 10 miles.  Now that we know one inch is 10 miles, we can multiply 10 x 8 to get 80.  Therefore, the real distance between the two citied is 80 miles.

Hope it helped and have a great day :)

Step-by-step explanation:

They have the two angles, and then the side after the angles

Answer:

42˚

Step-by-step explanation:

Answer:

42°

Step-by-step explanation:

Theorem of isosceles triangle says that the two adjacent angles that are not connected by two congruent lines are congruent.

Simple words:

L is the angle connected by both lines with the "ticks"

So that means K and M are congruent

Since K = 42°

M = 42°

Fun fact: If the angle name is something like ABC, the angle is technically B, because B is the vertex.

Answer:

C - (8×10) + (9×1) + (4×1/100)

Step-by-step explanation:

89.04

4 is in the hundredths place after the decimal. So it would ve equivalent to 1/100 because the 0 is taking the place of 1/10

:)

Answer:

Hello again! Your answer is C! (Sorry this is an edit)

Step-by-step explanation:

(8 x 10) + (9 x 1) + (4 x 1/10)

im not exactly sure how to explain this, but I studied this in 3rd grade so I believe I’m correct... if you solve the question, you’ll get 89.04

i can try my best to explain below...

I’ll start with the first part of the equation.

(8 x 10) ... this equals 80

next is (9 x 1) ... this equals 9

then we have (4 x 1/100) ... this equals 4/100, because 4 of 1/100 would be 4/100, translated to decimals would equal 0.04

now we already simplified the equation: 80 + 9 + 0.04

finally, the solution. (Solving the problem)

80 + 9 = 89

89 + 0.04 = 89.04

im sorry if this isn’t a detailed enough explaination, but this is the best I could do. Best of wishes on your assignment & have a nice day! (Brainliest? Lol.)

Answer:

The family used the pool for 8 months

Step-by-step explanation:

We know that the family paid a total amount of $1,350 dollars. We also know that they had to pay $350 dollars for joining the community pool. Lastly, they paid a monthly fee of $125 dollars. The value "x" represents months.

With that being said, here's our equation.

350 + 125x = 1,350

Subtract 350 from both sides and you should get this:

125x=1,000

Finally, divide 125 from both sides to get the x value.

x=8
