The lengths of text messages are normally distributed with a population standard deviation of 6 characters and an unknown population mean. If a random sample of 27 text messages is taken and results in a sample mean of 25 characters, find a 95% confidence interval for the population mean. Round your answers to two decimal places. z0.10 z0.05 z0.04 z0.025 z0.01 z0.005 1.282 1.645 1.751 1.960 2.326 2.576 You may use a calculator or the common z-values above.
Answer:
(22.74 ; 27.26)
Step-by-step explanation:
The confidence interval relation is stated as :
Mean ± Zcritical * σ/sqrt(n)
Mean = 25
σ = 6
The Zcritical at 95% = 1.96
Hence,
25 ± 1.96 * (6/sqrt(27))
25 ± 1.96 * 1.1547005
Lower boundary :
25 - (1.96 * 1.1547005) = 22.73678702
Upper boundary :
25 + (1.96 * 1.1547005) = 27.26321298
(22.74 ; 27.26)

Tucker got in his car and started driving toward his grandmother's house. After driving for 1 hour and 30 minutes, Tucker took a break for 40 minutes to have a snack. Then Tucker drove 1 hour and 40 minutes and finally arrived at his grandmother's house at 6:05 P.M. What time did Tucker start driving?
Answer: He started driving at 2:15 P.M.
Step-by-step explanation:
Answer:
3:05 P.M
Step-by-step explanation:
6:05 - 1 hour and 30 min = 5:25
5:25-40 minutes = 4:45
4:45 - 1 hour 40 minutes = 3:05 P.M
If h(x) = x3 + x and g(x) = 2x +3, then g(h(2))
Answer:
They both equal 23 so it’s a true statement
Step-by-step explanation:
h(x) = x3 + x and g(x)
=
h(2) = 2^3 + 2
= 8 + 2
= 10
g(h(2))
= g(10)
= 2*10 + 3
= 20 + 3
= 23
2x +3, then g(h(2))
=
h(2) = 2^3 + 2 = 8+2 = 10
Now we will substitute into g(h(2)
g(h(2)) = g(10)
Now we will substitute into g(x).
g(10) = 2*10 + 3 = 23
g(h(2)) = 23

Answer:
31°
Step-by-step explanation:
Angle KLN and Angle MLN equal 160° as said in the directions.
So 2y° + (3y + 5)° = 160° –– Combine like terms
5y + 5° = 160° ––Subtract 5 from both sides
5y° = 155° –– Divide both sides by 5 to get y alone
y = 31°

Mrs. Beppu's property has four sides. An aerial view of her property is shown below. What term best describes the shape of her property?
Answer:
rectangle
Step-by-step explanation:
From the picture attached below of the aerial view of Mrs. Beppu's house we can see that it is a rectangle. That is because it has 4 sides with only the parallels being the same size. Meaning that both the width and the length of the house are not the same. This removes the possibility of it being a square. Since all the angles seem to be right angles it also removes the possibility of it being a trapezoid. The best choice would be that it is a rectangle.

What does the equation 100+0.05p=0.25p represent?
The value of "p" will be "0.002".
Equation:According to the question,
[tex]100+0.05p=0.25p[/tex]By subtracting "0.25p" from both sides, we get
→ [tex]100+0.05p-0.25p=0.25p-0.25p[/tex]
[tex]100-0.2p=0[/tex]
[tex]100=0.2p[/tex]
[tex]p = \frac{0.2}{100}[/tex]

Answer:
Adults
= Percentage of adults * Total number of people who visited
= 56% * 1,575
= 882 adults
Teenagers
= Percentage of teenagers * Total number of people who visited
= 16% * 1,575
= 252 teenagers
Children
= 28% * 1,575
= 441 children

4. What is the axis of symmetry for h(x) = 19(x – 5)^2 + 6
Answer:
x = 5
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k ) are the coordinates of the vertex and a is a multiplier
h(x) = 19(x - 5)² + 6 ← is in vertex form
with vertex (h, k ) = (5, 6 )
The axis of symmetry is a vertical line passing through the vertex
with equation x = 5

What are the dimensions of the fenced in area if he only has 320 yards and the length is 5 yards more than 5 times the width
Answer:
Length = 134.16yds, width = 25.8yds
Step-by-step explanation:
Perimeter of the yard = 2(L+W)
L is the length
W is the width
If length is 5 yards more than 5 times the width, then;
L = 5W+5
Substitute
P = 2(5W+5+W)
P = 2(6W+5)
P = 12W+10
320 = 12W +10
12W = 320-10
12W = 310
W = 310/12
W = 25.8
Since L = 5W+5
L = 5(25.8)+5
L = 129.16+5
L = 134.16yds
Length = 134.16yds, width = 25.8yds
