Answer:
4. H0: u1= u2 Ha; u1≠ u2
5. The smaller value of p supports the null hypothesis.
Step-by-step explanation:
4. The null and alternate hypotheses are
H0: u1= u2 i.e there no difference between the mean pinch strengthof the two surgeries
against the claim
Ha; u1≠ u2 i.e there a difference between the mean pinch strengthof the two surgeries
It can be written like this as well
H0: u1 -u2= 0 i.e there no difference between the mean pinch strengthof the two surgeries
against the claim
Ha; u1 -u2≠ 0 i.e there a difference between the mean pinch strengthof the two surgeries
Part 5. The test having a p- value less than 0.05 tells that the null hypothesis cannot be rejected. Theres no evidence to reject the null hypothesis.
The smaller value of p supports the null hypothesis.
What is the volume of the square pyramid? 11cm and 11cm
Answer:
1331 feet3
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
*LOOK AT PICTURE FOR QUESTION*
F) 20.5 in
G) 14.74 in
H) 9.3 in
J) 10.1 in

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
Hope it Helps!:)
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.)
A map is drawn with a scale of 1/2 inch equal to 5 actual miles.if the map distance between two cities is 8 inch's,what is the real distance between these cities in miles
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 :)
The surface area of a cube is 54 square inches.
What is the volume of the cube?
What is the volume of the circle?
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.
In a study of simulated juror decision making, Braden-Maguire, Sigal, and Perrino (2005) investigated the type of verdict assigned by study participants after they read a 12-page summation of a case involving a battered woman who had shot and killed her husband. Of the 80 participants, 27 assigned a verdict of guilty, 49 a verdict of not guilty by reason of self-defense, and 4 a verdict of not guilty by reason of insanity. What type of chi-square test would the researchers use to determine if the distribution of verdicts differs from what would be expected by chance
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]

4. Solve the following inequality for b, showing all of your work carefully and completely
4b - 12 - 55 < 9b +8
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.

Donations of $375 in February to a homeless shelter are 250% of what they were in January. What were the donations to the shelter in January?
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

HURRYY!!!
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.

The cost for a pool membership for a family at a community pool is $350 plus $125 per month. A family paid a total of $1,350. How many
months did the family use the pool?
a-11
b-14
c-8
d-12
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
