A sample of 26 elements from a normally distributed population is selected. The sample mean is 10 with a standard deviation of 4. The 95% confidence interval for μ is _____. a. 6.000 to 14.000 b. 8.384 to 11.616 c. 8.462 to 11.538 d. 9.846 to 10.154
Answer:
B. 8.384 to 11.616
Step-by-step explanation:
We have
mean = 10
s = 4
n = 26
the degrees of freedom = n-1
= 26 - 1 = 25
α = 1-95%
= 1 - 0.95
= 0.05
α/2 = 0.05/2 = 0.025
using the t table
t0.025, 25 = 2.06
we find the margin of error
t * s/√n
= 2.06 * 4/√26
= 1.616
10-1.616 < μ < 10+1.616
= 8.384<μ<11.616
therefore option b is the right solution
This morning, the cafe served 8 coffees in all, 75% of which were regular. How many regular coffees did the cafe serve?
Answer:
6 regular coffees. Thank it if its helpful, thank you!
Step-by-step explanation:
75% of 8 is 6
Reasoning:
75/100*8/1=600/100
600/100=6!
Answer:
Regular coffee served by cafe = 75%* 8
= 75/100*8 = 6 coffees

What is the perimeter of ABC?
Perimeter = ___ units.
Answer:
12 units
Step-by-step explanation:
From the given figure,
AB=4 units & BC=3 units
By Pythagoras Theorem, [tex]AC^{2} = AB^{2} + BC^{2}[/tex]
Here, [tex]AC^{2} = 4^{2} + 3^{2}[/tex]
Thus, AC=5 units
Now, perimeter of triangle is equal to the sum of all sides.
Perimeter = AB + BC + AC = 4 + 3 + 5 = 12 units

substituting the equation x=4y - 12 into the equation -2y= x- 6. will produce what equation?
Step-by-step explanation:
Given that,
x=4y - 12 ....(1)
And
-2y= x- 6 ....(2)
Put equation (1) in equation (2). So,
-2y= (4y - 12)- 6
-2y = 4y - 12 -6
-2y-4y = -12-6
-6y = -18
y = 3
So, substituting x=4y - 12 into the equation -2y= x- 6 will produce y = 3.

The greatest common factor (GCF) of x^3, x^7, x^9 is ?
Please help
Answer:
[tex]x^3[/tex]
Step-by-step explanation:
Let the greatest common factor of [tex]a,b,c[/tex] such that [tex]a,b,c \in\mathbb{Z}[/tex] and they are not all equal to zero, [tex]d[/tex] is the common divisor of [tex]a[/tex] and [tex]b[/tex]. Therefore, [tex]d \mid a[/tex] and [tex]d \mid b[/tex]
You can write
[tex]D(a) = \{d \in\mathbb{Z} : d \mid a\}[/tex]
[tex]D(b) = \{d \in\mathbb{Z} : d \mid b\}[/tex]
The greatest common factor of [tex]a,b[/tex] is given as
[tex]D(a,b) = \{d \in\mathbb{Z} : d \mid a \text{ and } d \mid b\}[/tex]
and
[tex]D(a, b) = D(a) \cap D(b)[/tex]
This happens because [tex]D(a,b)[/tex] is upper bounded because if [tex]a\neq 0[/tex] then [tex]d \leq |a|[/tex]
for all [tex]d\in D(a, b)[/tex]. Therefore, the set [tex]D(a, b)[/tex] has the greatest elements.
Taking [tex]x^3, x^7, x^9[/tex] such that [tex]x>0[/tex]
You can note that [tex]x^7 = x^3 \cdot x^4[/tex] and [tex]x^9 = x^3 \cdot x^6 = x^3 \cdot x^3 \cdot x^3[/tex]
Therefore, the greatest common factor is [tex]x^3[/tex]
Note: [tex]x^3 \cap x^7 \cap x^9 = x^3[/tex]
Simplify 4(3 − 2) − 7( + 5) Show work
Answer:
- 31
Step-by-step explanation:
4(3 − 2) − 7(5)
Subtract 3 - 2
4(1) - 7(5)
Multiple -7 and 5
4 - 35
Subtract 4 - 35
The correct answer is -31.
The simplified form of 4(3 − 2) − 7( + 5) is -31.
To simplify the given expression, using (PEMDAS/BODMAS) and simplify each part step by step.
4(3 − 2) − 7( + 5)
First, simplify the expressions inside the parentheses:
3 − 2 = 1
+ 5 = 5
then, the expression becomes:
4(1) − 7(5)
Next, let's perform the multiplications:
4(1) = 4
7(5) = 35
The expression now becomes:
4 − 35
Finally, let's perform the subtraction:
4 − 35 = -31
Therefore, the simplified form of 4(3 − 2) − 7( + 5) is -31.

1/X+5 what is the value of
(f/g)(8)
9514 1404 393
Answer:
(f/g)(8) = -104/41
Step-by-step explanation:
Fill in the value for x and do the arithmetic.
f(8) = 3 -2·8 = 3 -16 = -13
g(8) = 1/8 +5 = (1+40)/8 = 41/8
Then the ratio is ...
(f/g)(8) = f(8)/g(8) = -13/(41/8) = -13(8)/41
(f/g)(8) = -104/41

The states of nature refer to future events, not under the control of the decision maker, which may occur. States of nature should be defined so that they are mutually exclusive and collectively exhaustive.
An experiment has three steps with three outcomes possible for the first step, two outcomes possible for the second step, and five outcomes possible for the third step. How many experimental outcomes exist for the entire experiment
Answer:
30 experimental outcomes exist for the entire experiment.
Step-by-step explanation:
Fundamental counting principle:
States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.
In this question:
Three outcomes possible for the first step.
Two for the second step.
Five for the third step.
How many experimental outcomes exist for the entire experiment?
Steps are independent, so, by the fundamental counting principle:
3*2*5 = 6*5 = 30
30 experimental outcomes exist for the entire experiment.

Eight pipes were turned on to fill the pool in 36 hours. Then, after 12 hours some of the pipes were turned off, and the rest of the pool was filled in 32 hours. How many pipes were turned off?
Answer:
2 pipes
Step-by-step explanation:
So.. I'm not too sure either, but I'll try to solve it.
Equation: 4x=8 when x=number of pipes turned off after 12 hours
Since there were initially 8 pipes and there are 4 hours between 36 planned hours to fill the whole pool and 32 actual hours passed to fill the rest of the pool, you multiply them.

A train leaves at 15:43 and arrives at 17:13. It travelled at an average speed of 75 km/h.
How far did it travel? Give your answer in km to 1DP.
Can anyone answer this
Answer:
Distance cover by train = 112.5 km
Step-by-step explanation:
Given;
Speed of train = 75 km/h
Time started = 15:43 min
Time ended = 17:13 min
Find:
Distance cover by train
Computation:
Time started = 15:43 min = 15.716 hour
Time ended = 17:13 min = 17.216 hour
Total time taken = 17.216 - 15.716
Total time taken = 1.5 hour
Distance cover by train = Total time taken x Speed of train
Distance cover by train = 75 x 1.5
Distance cover by train = 112.5 km
