the age of children in kindergarten on the first day of school is uniformly distributed between 4.74 and 5.85 years old. a first time kindergarten child is selected at random. round answers to 4 decimal places if possible. the mean of this distribution is the standard deviation is the probability that the the child will be older than 5 years old? the probability that the child will be between 4.84 and 5.34 years old is if such a child is at the 9th percentile, how old is that child? years old.
a) The mean distribution is 5.295.
b) The standard deviation is 0.1026
c) The probability that the child will be older than 5 years old is 0.7657
d) The probability that the child's age is between 4.84 and 5.34 is 0.4504
e) At the 9th percentile, the age of the child is 5.739 years old.
Given interval distribution is
4.74 - 5.85.
a) Firstly, we will find the mean distribution,
Mean distribution = Sum of intervals / Number of intervals
= 4.74+5.85 / 2
= 5.295.
Hence, the mean distribution is 5.295.
b) Now, we will find the standard deviation,
We use the formula:
SD = [tex]\sqrt{\frac{(b-a)^{2} }{12} }[/tex]
b = 5.85
a = 4.74
SD = [tex]\sqrt{\frac{(5.85-4.74)^{2} }{12} }[/tex]
SD = [tex]\sqrt{\frac{(1.11)^{2} }{12} }[/tex]
SD = 0.1026
Hence, the standard deviation is 0.1026
c) The probability that the child will be older than 5 years will be
p(older than 5) = 5.85 - 5 / 5.85 - 4.74
= 0.85 / 1.11
= 0.7657
Hence, the probability that the child will be older than 5 years old is 0.7657
d) The probability that the child will be between 4.84 and 5.34 years old will be
p(between 4.84 and 5.34) = 5.34 - 4.84 / 5.85 - 4.74
= 0.5 / 1.11
= 0.4504
Hence, the probability that the child's age is between 4.84 and 5.34 is 0.4504
e) If the child is at the 9th percentile, the age will be
At the 9th percentile = 4.74 + 9/100 ×(5.85 - 4.74)
= 4.74 +(0.9)(1.11)
= 4.74 + 0.999
= 5.739
Hence, at the 9th percentile, the age of the child is 5.739 years old.

At a carnival game, it cost Noah $12 to toss 30 rings. Fill out a table of equivalent ratios and plot the points on the coordinate axes provided.
The equivalent ratios table is:
Toss Dollars
5 2
30 12
45 18
See the diagram in the attachment that shows the plotted points.
What are Equivalent Ratios?Equivalent ratios are ratios that have the same value when they are compared together.
For example, 4/6 = 2/3, therefore, the equivalent ratios are 2:3 and 4:6.
Create an equation that models equivalent ratios that can be used to complete the table if:
x = toss
y = dollars
Therefore, given that 30 toss equals $12,
Constant of proportionality, k = y/x = 12/30
k = 2/5.
Plug in the value of k into y = kx:
y = 2/5x.
Therefore:
2 dollars (y = 2), will give:
2 = 2/5(x)
x = 10/2
x = 5 toss
45 tosses (x = 45) will need:
y = 2/5(45)
y = 18 dollars
The equivalent ratios table would be:
Toss | Dollars

The total number of miles for the four trips is 25 miles.
Given that;
Linda traveled for one hour each day for four days at a speed that made her cover one mile in an even number of minutes. After the first day, she started to lose speed, and it took her 5 minutes longer to complete a mile than the day before. Her journey distance was also an integer amount of miles throughout the four days.
We know that,
Distance is a product of speed and time. We need to find the distance here with the use of the given conditions, time is 1 hour.
Speed = Distance / Time
Hence, speed is 1 mile per x minutes because we want to distance by multiplying the time and speed together yielding 60 min * 1 mile / x mins.
Minutes cancel out, so now we have 60/x as our distance for the first day.
The distance for the given case;
⇒ [tex]\frac{60}{x},\frac{60}{x+5},\frac{60}{x+10},\frac{60}{x+15}[/tex]
It is given that x = 5;
⇒ [tex]\frac{60}{5},\frac{60}{10},\frac{60}{15},\frac{60}{20}[/tex]
= 12 + 6 + 4 + 3
= 25
The total number of miles for the four trips is 25 miles.

The image of ΔABC after a reflection across Line E G is ΔA'B'C'.
2 triangles are shown. Line E G is the line of reflection. Line segment D D prime has a midpoint at point F. Line segment C C prime has a midpoint at point G. Points B and B prime share a point. Angle C G F is a right angle.
Which triangle must be a right triangle and why?
ΔBGC is right because Line EG is perpendicular-to CC'.
What is Reflection?A reflection image or reflection point is the mirror image of a figure in the axis or plane of reflection.
Each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point, but is on the other side of the line. This transformation is known as a reflection over line. The size and form of the image in a reflection are identical to those of the pre-image.
Given:
On the line of reflection will be the midpoints of the segments connecting a triangle vertex with its reflected image. The segment will be parallel to the reflection's line.
A triangle will be considered correct in this situation if it has a leg that is a part of the segment connecting the reflected points and a leg that is on the line of reflection. Such a triangle is the BGC.
Hence, BGC is right triangle.

The function g(x) is continuous on the closed interval [8, 10] and differentiable on the open interval
(8, 10). The value x = 8.5 satisfies the conditions of the Mean Value Theorem on the interval [8, 10].
What is g(10) given g'(8.5) = -9 and g(8) = 6?
Answer:
g(10) = -12
Step-by-step explanation:
Mean Value Theorem
If f is continuous on [a, b] and differentiable on (a, b), then there is a number c such that a < c < b and:
[tex]f'(c)=\dfrac{f(b)-f(a)}{b-a}[/tex]
We are told that the function g(x) is continuous on the closed interval [8, 10] and differentiable on the open interval (8, 10).
Therefore:
a = 8b = 10Given:
g'(8.5) = -9g(8) = 6As 8 < 8.5 < 10 then c = 8.5:
[tex]\begin{aligned} \implies g'(8.5)=\dfrac{g(10)-g(8)}{10-8}&=-9\\\\\dfrac{g(10)-6}{2}&=-9\\\\g(10)-6&=-18\\\\g(10)&=-12\end{aligned}[/tex]
Lucia makes braided key chains out of cotton cord. For every 8 feet of cotton cord she has, she can make 3 braided key chains. Use a model to represent the relationship between the feet of cotton cord and the number of key chains.
(NEED HELP ASAP PLEASE)
A model for representing the relationship between the number of key chains and the number of feet of cotton cord is: 8x - 3y = 0.
Define the term linear equation?Linear equations are first-order equations. Lines with in coordinate system are determined by linear equations. When the equation contains a degree 1 homogeneous variableSince Lucia creates braided key chains from out cotton cord and can create 3 braided key chains per each 8 feet of cotton cord she does have, the following equations must be performed via cross multiplication to symbolize the relationship between both the feet of cotton cord as well as the number of key chains but also obtain the number of cotton cord Lucia requires to achieve 5 key chains:
8 cotton cords = 3 key chains
Let the total length in feet of cotton cords be x.
And the total number of key chain made be y.
Then, the linear equation formed as;
8x = 3 y
8x - 3y = 0
Thus, a model for representing the relationship between the number of key chains and the number of feet of cotton cord is: 8x - 3y = 0.
