Answer:
Change the confidence interval.
Step-by-step explanation:
The confidence interval should be altered . If a 95 % or 90% confidence interval is set then better results can be obtained for student satisfaction.
A 90 or 95 or 99 percent confidence interval will show a greater range of the data that lies within or without the given criteria.
95 % confidence interval does not mean that the probability is 95% . It means that we are 95% of the data lies or does not lie within the specific range.
This gives better results as compared to 60- 80 % confidence intervals.
If 95% of the students are satisfied as compared to 60% or 80% , this shows more accuracy.

What is a number that has
a 6 in the thousandths place, a 5 in the
hundredths place, and a 0 in the tenths
place. Then write a number less than
your number and a number greater than
your number.
Answer:
Step-by-step explanation:
there is no real answer:
Ok, so a number with all of those characteristics would be 6501, but the last digit can be anything from 1 to 9. a number greater could be anything, so i would choose 6601, and less would be 6401.
The number is 0.056.
The number less than the number 0.056 is 0.0056.
And the number greater than the number 0.056 is 0.56.
What is a place value?Place value, which is related to a digit's location in a number, is the amount that each digit is worth.
A number that has a 6 in the thousandths place, a 5 in the hundredths place, and a 0 in the tenths place.
Let the number is 0.056
And the number greater than the number 0.056 is 0.56.
The number less than the number 0.056 is 0.0056.
Therefore, the numbers are 0.056, 0.56 and 0.0056 in the respective order.

Answer:
1.25
Step-by-step explanation:
First we should fill in what we know. They mentioned that the y would be the numerator (# on the top) and the x would be the denominator (# in the bottom).
[tex]\frac{3}{24} =\frac{y}{10}[/tex] <---- This will be your proportion
Now we will cross multiply and make a equation. So we will do 3 * 10 which equals 30 and then 24 * y which is 24y. So now our equation will look like this.
[tex]30=24y\\y=1.25[/tex]
Then when you solve the equation you'll get 1.25

Answer:
The answer is x = 15.
Step-by-step explanation:
To solve this problem, we must first notice that the two angles given are supplementary (their sum adds to 180 degrees).
This lets us create the following equation:
(6x-5) + (6x+5) = 180
We can get rid of the parentheses and simplify the left side of the equation.
6x + 6x - 5 + 5 = 180
12x = 180
To solve for x, we must divide both sides of the equation by 12.
x = 180/12 = 15
Therefore, the correct answer is x = 15.
Hope this helps!

Answer:
Bagels are 4 and Muffins are 2
Step-by-step explanation:
solve the system of equations
Answer:
Bagels are 4 and the muffins are 2 or the first answer
Step-by-step explanation:
2b+m=10
3b+m=14
we can subtract the equations
-b=-4
multiply both sides by -1 to get
b=4 meaning a bagel is four dollars
we can then subsitute this
2(4)+m=10
8+m=10
subtract 8 from both sides
m=2
subsitute these into the second equation to check
3(4)+(2)=14
12+2=14
14=14
Therefore the answer is Bagels are 4 and the muffins are 2 or the first answer

of a gallon of red paint to paint 3/5
of her wall.
How many gallons of red paint will she use to paint her whole wall?
A) 21/50
B)7/15
C) 1 1/6
D) 1 3/10
Answer:
1 1/6 gallons will paint the whole wall
Step-by-step explanation:
7/ 10 gallon paints 3/5 of wall
x gallon will paint 1/1 of wall
7/10 * 1 = x * 3/5
7/10 = 3x/5
3x * 10 = 5 * 7
30x = 35
x = 35/30
x = 7/6 = 1 1/6 gallons
8. Aaron and Zelly want to rent a tandem bike so that
they can ride together. The rental for a tandem bike is
$18.50 per hour plus $3 for each helmet. Aaron and
Zelly have $80 to spend on the bike rental. Which
equation can be used to find h, the number of hours
they can rent a tandem bike? (hint: if you do not know
what a tandem bike is, you need to look it up!)
80 = 6h + 18.50
80 = 18.50h + 3
80 = 18.50h + 6
80 = 3h + 18.50
Answer:
[tex]80 = 18.50h + 6[/tex]
Step-by-step explanation:
Given
[tex]Amount = \$80[/tex]
[tex]Rent = \$18.50[/tex] per hour
[tex]Helmet = \$3.0[/tex]
[tex]Individuals =2[/tex]
Required
Derive an expression for the scenario
A tandem bike allows 2 individuals to ride on it at a time.
So, they will only pay for one rental fee because both can ride on it at the same time.
However, they need to get separate helmets.
For Helmets, they will spend:
[tex]\$3 * 2 =\$ 6[/tex]
For Rental, they will spend
[tex]\$18.50 * h = \$18.50h[/tex] for h hours.
[tex]Total = Rentals + Helmets[/tex]
[tex]Total = 18.50h + 6[/tex]
Recall that they have just $80 to spend
So, substitute 80 for total
[tex]80 = 18.50h + 6[/tex]
Hence, option C answers the question.
Write an equation of a line that is parallel to the given line.

Describe the graph of y = |x - 2| + 4
Answer:
Step-by-step explanation:
Note that this function resembles the absolute value function y = |x|.
The graph of y = |x| has its vertex at (0, 0) and opens up in a v-shape.
The graph of y = |x - 2| looks the same as that of y = |x|, but the entire graph has been translated 2 units to the right.
The graph of y = |x - 2| + 4 is that of y = |x - 2|, translated 4 units up.
