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:

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

Answer:

x = 139

Answer:

The probability is 1/10.

Step-by-step explanation:

Since there are 10 shirts in total, and only 1 red shirt, the probability of choosing a red shirt is 1/10.

It would be INSANLEY FANTABULOUS if I could receive brainliest!!!!!

Answer:

It would be 11 since in the equation 11(x+3), you would need to multiply 11 * x along with 11 * 3 to get your answer.

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:

$150

Step-by-step explanation:

$375 was donated to a homeless shelter in February

250% of this sum was donated in January

Hence the amount donated in January can be calculated as follows

375×100/250

= 37500 250

= 150

Hence the amount donated in January is $150

Answer: [tex]\dfrac{43}{4}\ \text{Gallons}[/tex]

Step-by-step explanation:

Given

The first one has 4 gallons and 2 quarts of juice

The second one has 1 [tex]\frac{3}{4}[/tex] gallons more than the first

First has

[tex]\Rightarrow 4+\dfrac{2}{4}\\\\\Rightarrow \dfrac{9}{2}\ \text{Gallons}[/tex]

second has

[tex]\Rightarrow 1\dfrac{3}{4}+\dfrac{9}{2}\\\\\Rightarrow \dfrac{7}{4}+\dfrac{18}{4}\\\\\Rightarrow \dfrac{25}{4}\ \text{Gallons}[/tex]

together it is

[tex]\Rightarrow \dfrac{25}{4}+\dfrac{18}{4}\\\Rightarrow \dfrac{25+18}{4}\\\Rightarrow \dfrac{43}{4}\ \text{Gallons}[/tex]

Answer:

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:

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 :)
