Answer:
The 95% of confidence intervals
(2.84 ,2.99)
Step-by-step explanation:
A random sample of 20 accounting students results in a mean of 2.92 and a standard deviation of 0.16
given small sample size n =20
sample mean x⁻ =2.92
sample standard deviation 'S' =0.16
level of significance ∝ = 0.95
The 95% of confidence intervals
the degrees of freedom γ=n-1 =20-1=19
t-table 2.093


(2.92-0.0748,2.92+0.0748)
(2.84 ,2.99)
Therefore the 95% of confidence intervals
(2.84 ,2.99)

Here’s why:
⸻⸻⸻⸻
I am assuming that '3=x divided by 3' is supposed to be
.
⸻⸻⸻⸻
The first, second, and fourth equations have x divided by a number. To isolate x, we would have to use the multiplication property of equality.
⸻⸻⸻⸻
For the third one (
), the variable 'x' is being subtracted by 6. We would have to use the addition property of equality to isolate x.

Hope this helps you. I apologize if it’s incorrect.
Answer:
Step-by-step explanation:
B/c the bigger triangle is a copy of the smaller we can say
8
/ 12 = x / 8
then, solve for x
8
(8
/12) = x
(64 *3) 12 = x
192 /12 = x
16 = x
nice, the first answer looks good , then :P
The answer is 29
First you do 60/10 which is 6
After you do 3 x 3 x 3 which is 27.
Then you subtract 27-6 which is 21.
Last you do 21+8 and you get 29
Answer:
<h2>
y = 16/25x³</h2>
Step-by-step explanation:
If y is inversely proportional to a^3, this is expressed as;
y∝1/a³
y = k/a³ where k is the proportionality constant
Given a=2, y=10, then 10 = k/2³
k = 10*2³
k = 80
Substituting k = 80 back into the formula;
y = 80/a³ ............. 1
Similarly, if a is directly proportional to x, then a ∝ x i.e a = kx
If x=4, a=20 then;
20 = 4k
k = 20/4
k = 5
Substituting k = 5 back into the formula;
a = 5x ....... 2
Substitute equation 2 into 1;
y = 80/a³
y = 80/(5x)³
y = 80/125x³
y = 16/25x³
<em>Hence the formula for y in terms of x is y = 16/25x³</em>
