Answer:
True , null
Step-by-step explanation:
Mostly the true hypothesis is the null hypothesis .
We test the true hypothesis , the null hypothesis against the claim provided which is named as alternate hypothesis.
When the false hypothesis is the null hypothesis , type II error is made.
Confounded in statistics means when the alternative explanations cannot be eliminated.But we have the alternate hypothesis in hypothesis testing.
So option 1 is correct
Find the area. Round any decimals to the nearest tenth
Answer:
1.4
Step-by-step explanation:
Since we're finding the area, we need to multiply 1.2 times 1.2, which would give us 1.44, and since it says to round to the nearest tenth, we need to round it. If the number is 4 or under, we round down, if it's 5 and up we round up. In this case, we round down- so we end up with 1.4.
Answer:
A = L x 4
1.2cm x 4 = 4.8 cm^3

Using the diagram below, determine which
statement is NOT true.
Answer: C
Step-by-step explanation:
Of the first 52 contestants, exactly 12 contestants win the game. How does the actual number of winners compare to the expected number of winners? What needs to happen for the experimental probability to approach the theoretical probability? Explain
pls help me
Answer:
Expected number of winners with 52 contestants:52*5/13 = 20.The experiment result is almost twice less (12 vs 20).In order to change the results of experimental probability some of the letters may need swapped, (probably the letters are in alphabet order) but for this we need more data.
Step-by-step explanation:
Experimental probability is probability that is determined on the basis of the results of an experiment repeated many times. Theoretical probability is probability that is determined on the basis of reasoning. Probability is a value between (and including) zero and one.

Please help me, this is like the easiest thing but I'm stuck
Answer: A. 384 sq. mm
Step-by-step explanation: The area for the square is 12x12 or 144. The area for a triangle is base x height x 1/2. Therefore, that would be 12 x 10 x 1/2 or 60. There are 4 sides to this pyramid, so 60 x 4 = 240. We then add 144 and 240 to get 384 sq. mm.
What are all possible values of x? (This is not a right triangle!)
Answer:
solution set for x = { 4,5,6}
Answer:
2<x<12
Step-by-step explanation:
Firstly, look at this formula-
a-b<x<a+b
If we make 7, A, and 5, B, then the formula would be 7-5<x<7+5
So after you do the math it would be 2<x<12
Hence, the answer is 2<x<12

(a) Compute the stationary distribution π. (b) Is the stationary distribution π also the limiting distribution? Give a reason for your answer.
Answer:
The responses to the given can be defined as follows:
Step-by-step explanation:
For point a:
fixing probability vector that is [tex]W = [a b c][/tex]
[tex]\therefore[/tex]
relation: [tex]WT =W[/tex]
[tex]\to 0.5a+0.3b+0.2c=a ..................(1)\\\\ \to 0.4a+0.4b+0.3c=b..............(2)\\\\ \to 0.1a+0.3b+0.5c=c.................(3)[/tex]
solving the value:
[tex]a=0.3387 \\\\ b=0.3710\\\\ c=0.2903[/tex]
Therefore the stationary distribution [tex]\pi =[0.3387 \ 0.3710\ 0.2903][/tex]
For point b:
[tex]\pi[/tex] will be limiting distribution if [tex]\pi_j=\lin_{n\to \infity} (X_n=\frac{j}{X_0}=i) \Sigma_{\sqrt{j}} n_j=1[/tex]
[tex]\pi[/tex] satisfies the above condition so, it is limiting the distribution.

 Jamila earns $14,$11,$20,$15,$20 from babysitting 7 times. Find the interquartile range or IQR

Step-by-step explanation:
For 11 days straight, Mike drove the same distance every day going to and coming from work. On the 12th day, he drove an extra 7 miles. If Mike drives 91 miles in total in those 12 days, write an expression to find the distance he travels each day going to and from work.
Answer:
A) The algebraic expression
= 12x + 7 = 91
B) He drives 7 miles per day
Step-by-step explanation:
For 11 days straight, Mike drove the same distance every day going to and coming from work.
Step 1
We are told : Mike drives 91 miles in total in those 12 days,
On the 12th day, he drove an extra 7 miles.
Hence:
91 miles - 7 extra miles
= 84 miles
Step 2
The number of miles he drives per day:
84 miles/12
= 7 miles per day
Step 3
The expression we can use to find the distance he travels each day going to and from work is written as:
Let the number of miles he travels be day = x
12x + 7 = 91 miles
12x + 7 = 91
12x = 91 - 7
12x = 84
x = 84/12
x = 7 miles per day
What is the greatest common factor that can be factored out of the polynomial 64x5 – 16x3 + 80x
Answer:
GCF = 16
Step-by-step explanation:
All 3 coefficients are divisible by 16, and 16 is the greatest factor that can divisible.
Answer:
GCF = 16
Step-by-step explanation:
64/16 = 4
16/16 = 1
80/16 = 5
All of the terms in the polynomial are able to be divided by 16 the GCF.

For the drawing, provide the missing lengths. x= hypotenuse y= leg
Answer:
Step-by-step explanation:
for hypotenuse
take 30 degree as reference angle
using sin rule
sin 30=opposite /hypotenuse
1/2=5/hypotenuse
10=hypotenuse
for base
using pythagors theorem
H^2=P^2+B^2
10^2=P^2+5^2
100-25=P^2

I need help please I dont get this
Answer:
Step-by-step explanation:
Since this is a 30-60-90 triangle, we need the Pythagorean triple for such a triangle. the side length across from the 30 degree angle is labeled as x, the side across from the 60 degree angle is x√3, and the hypotenuse is 2x. Since we know the side length of the side across from the 60 degree angle, we use that identity and solve for x:
[tex]x\sqrt{3}=18[/tex] and
[tex]x=\frac{18}{\sqrt{3} }[/tex] and rationalizing the denominator,
[tex]x=\frac{18}{\sqrt{3} }*\frac{\sqrt{3} }{\sqrt{3} }=\frac{18\sqrt{3} }{3}=6\sqrt{3}[/tex]
This is the side length of the side across from the 30 degree angle. In order to find the hypotenuse, we have to multiply this value by 2 to get
12√3, the third choice down.

In a class of students, the following data table summarizes how many students passed
a test and complete the homework due the day of the test. What is the probability that
a student chosen randomly from the class did not complete the homework?
Answer:
3/16
Step-by-step explanation:
The total number of students = no. of students passed + number of students who failed.
i.e, 13+3=16
probability = 3/16 = 0.1875

Photos-To-Go printed 2,102 copies of a brochure for a travel agency. The brochure included 5 photos of popular vacation destinations. How many times will all 5 photos appear in all of the printed brochures? How do you know your answer is reasonable?
Answer:
All 5 photos will appear once in all the printed brochures
Step-by-step explanation:
Given
[tex]Copies = 2102[/tex]
[tex]Photos =5[/tex]
Required
The number of times the photo will appear
The interpretation of the question is to determine the number of times the 5 photos will appear in each copy.
From the question, we understand that the photos will appear once in a copy.
By extension, the 5 photos will appear once in other copies.
