Answer:

Step-by-step explanation:

Hi!

So first we do the parenthesis

( 5\frac{3}{4} - 1 \frac{5}{6}) =

Since 4 and 6 ≠ (does not equal to)

We change 4 and 6 to a number they have in common so, that number is 12 which is the lcm (least common factor). We are going to multiply 3 for each number (3 and 4) and 2 for 5 and 6, so

3/4 x 3 = 9/12 = 5 9/12

5/6 x 2 = 10/12 = 1 10/12

Now we substract,

  5 9/12

-  1 10/12

_________

4 1/12


now that we have this answer we will substract 4 1/12 from 10 which would be

5 11/12


hope this helped!! Good luck! Brainliest? :) <3

Which of the following are statistical questions? Select all that apply.
user100 [1]

Answer:

I think A and B

Step-by-step explanation:

• A statistical question is a question that has more than one possible answer ( and can be answered by collecting data) where there will be variability in the data. for instance an example would be " How old are the students in this room?"

• However a non statical question has only one answer for instance "How old are you?"

both a and b dont have specific answers because it's not talking about a specific high school students or a specific soccer team. i would guess those are correct, but using the information from above you can also see what you think! hope this helps :)

Please help me... I will mark brainliest if you do ;)
Tasya [4]

Answer:

86

Step-by-step explanation:

The sum of the angles in a quadrilateral is 360 degrees

since EF is parallel to HG

m < E + m< H =180

y + 10 + 2y -31 =180

-21+ 3y= 180

3y = 180 + 21

3y = 201

y=67

m <E = 67 + 10 =77

m < F = 2*67 -40= 134 -40=94

m < H = 2*67-31 = 134 -31 = 103

m < G = 360 - (m<E+ m < F + m < H)

= 360 - ( 77+94+103)

= 360- 274

=86

At Southside middle school 40%of student play an instrument.there are 305 student.how many students play an instrument
Nadusha1986 [10]
You simply use this operation:
- total students are 305, we need to find how many of thm play instrumenst if 40% does.
40% can be rewrited as 0,4 in decimal.
than we simply utilise a basic percentage operation which allows us to find A PART of somethin=>
305×0,4= students who instruments.

Fluoxetine, a generic anti-depressant, claims to have, on average, at least 20 milligrams of active ingredient. An independent l
san4es73 [151]

Answer:

t=\frac{18.7-20}{\frac{5}{\sqrt{80}}}=-2.326    

df=n-1=80-1=79  

p_v =P(t_{(79)}  

Step-by-step explanation:

Information given

\bar X=18.7 represent the sample mean for the content of active ingredient

s=5 represent the sample standard deviation for the sample  

n=80 sample size  

\mu_o =20 represent the value that we want to test

t would represent the statistic

p_v represent the p value for the test

System of hypothesis

We need to conduct a hypothesis in order to check if the true mean for the active agent is at least 20 mg, the system of hypothesis would be:  

Null hypothesis:\mu \geq 20  

Alternative hypothesis:\mu < 20  

The statistic would be:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}  (1)  

Now we can calculate the statistic:

t=\frac{18.7-20}{\frac{5}{\sqrt{80}}}=-2.326    

P value

The degrees of freedom are calculated like this:

df=n-1=80-1=79  

Since is a one left tailed test the p value would be:  

p_v =P(t_{(79)}
