Answer:

line graph

Step-by-step explanation:

Line graphs easily help the visual learner to interpret data and understand peaks and decreases in certain levels. It connects data points and allows people to see what is actually going on.

Answer:

line graph

Step-by-step explanation:

The explanations of each plot are:

Scatter plot

It is used to see the correlation between two variables. The correlation can be positive (increases), negative (decreases) or zero (no correlation at all). This plot can be used to draw a trend line to study the correlation between variables using an equation, generally a line and which prosses is call line regression.

Line graph

Is like the scatter plot but instead of leaving the data or points without connection the line graph connects the points, representing the data, with a line, so to easily show a tendency between variables, which generally tends to increase.

This plot is an easy way to show a tendency, but the scatter plot can give more statistical information about a correlation between variables.

box-and-whisker plot

Shows the median and the quartiles of the data, i.e. shows a interval in which the recollected data can be found and its frequency of repetition.

stem-and-leaf plot

Allows to simultaneously see the frequency distribution of the variable and its graphic representation and its constructed by separating, in each data, the last digit of the right (the leaf) to the remaining digits (the Stem).  

So, to easily show numerical data in ascending order it can be used the line graph, but it can be used de scatter plot to give deeper statistical information too.

Answer: more then 190

Step-by-step explanation:

if you multiply $19 by 12 (12 months in a year) you get $228

Miss Lacey will have to pay more than $190 for the gym membership.

A product is the result of the multiplication, an expression that identifies factors to be multiplied.

Miss Lacey is paying $19 p.m for the gym membership fees. So she will have to pay for one year =19*12 because there are 12 months in a year.

=218

which is greater than $218.

Hence Miss Lacey will have to pay more than $190 for the gym membership fees.

Answer:

AE=3

Step-by-step explanation:

1. Consider right triangle BOh. In this triangle, OB=10 (hypotenuse), OH=6 (leg), then by the Pythagorean theorem,

[tex]BH^2=BO^2-OH^2\\ \\BH^2=10^2-6^2\\ \\BH^2=100-36\\ \\BH^2=64\\ \\BH=8.[/tex]

2. Since OH⊥BC, then BC=2BH=16.

3. Use the secants property: If two secant segments are drawn to a circle from the same external point, the product of the length of one secant segment and its external part is equal to the product of the length of the other secant segment and its external part.

Thus,

[tex]AE\cdot FA=AB\cdot AC.[/tex]

So,

[tex]AE\cdot (AE+9)=2\cdot (2+16)\\ \\AE(AE+9)=36\\ \\AE^2+9AE-36=0\\ \\D=9^2-4\cdot (-36)=81+144=225\\ \\AE_{1,2}=\dfrac{-9\pm\sqrt{225}}{2}=-12,\ 3.[/tex]

The segment cannot be of negative length, therefore, AE=3.

Intersecting Secant Theorem helps to establish the relation between two secants of a circle. The length of the side AE will be equal to 3 units.

When two line secants of a circle intersect each other outside the circle, the circle divides the secants into two segments such that the product of the outside segment and the length of the secant are equal to the product of the outside segment and the other secant's length.

a(a+b)=c(c+d)

If we look into the triangle BOH, then the length of the side BH using the Pythagoras theorem can be written as,

[tex]OB^2=OH^2+BH^2\\\\10^2 = 6^2 + BH^2\\\\BH= 8\rm\ units[/tex]

Now, the length of BC will be twice the length of BH, therefore, the length of the line BC can be written as,

[tex]\text{Length of BC} = 2 \times (\text{Length of BH})\\\\\text{Length of BC} = 2 \times 8 = 16\rm\ units[/tex]

Now, using the Intersecting secant theorem the length of AE can be written as,

[tex](AB \times AC) = (AE \times FA)\\\\2(2+16) = AE(AE+9)\\\\36=AE^2+9AE\\\\AE^2+9AE-36 = 0\\\\AE^2+12 AE - 3AE -36=0\\\\AE(AE+12)-3(AE+12)=0\\\\(AE-3)(AE+12)=0\\\\AE = 3, -12[/tex]

Since the length can not be negative, therefore, the length of the side AE will be equal to 3 units.

Answer:

The mean absolute deviation (MAD) of this data set is 2.4

Step-by-step explanation:

step 1

Find the mean

To find out the mean sum all values and divide by the number of values in the data set

we have the set of data

[tex][2, 4, 7, 2, 3, 7, 9, 3, 1, 7][/tex]

The number of values is 10

so

The mean is equal to

[tex][2+4+7+2+3+7+9+3+1+7]/10=45/10=4.5[/tex]

step 2

Find out the absolute value of the difference of each value from that mean

[tex]\left|2-4.5\right|=2.5[/tex]

[tex]\left|4-4.5\right|=0.5[/tex]

[tex]\left|7-4.5\right|=2.5[/tex]

[tex]\left|2-4.5\right|=2.5[/tex]

[tex]\left|3-4.5\right|=1.5[/tex]

[tex]\left|7-4.5\right|=2.5[/tex]

[tex]\left|9-4.5\right|=4.5[/tex]

[tex]\left|3-4.5\right|=1.5[/tex]

[tex]\left|1-4.5\right|=3.5[/tex]

[tex]\left|7-4.5\right|=2.5[/tex]

so

we have

[tex][2.5, 0.5, 2.5, 2.5, 1.5, 2.5, 4.5, 1.5, 3.5, 2.5][/tex]

step 3

we know that

The Mean Absolute Deviation (MAD) is the mean of those distances

[tex][2.5+0.5+2.5+2.5+1.5+2.5+4.5+1.5+3.5+2.5]/10=24/10=2.4[/tex]

therefore

The mean absolute deviation (MAD) of this data set is 2.4

Answer:

3x + y = 12

Step-by-step explanation:

x = 6 - t

y = 3t - 4

We have to convert these equations in rectangular form which means that we have to express them in terms of x and y only. For this we have to eliminate "t".

From first equation we get the value of t as:

x + t = 6

t = 6 - x

Using this value in second equation, we get:

y = 3(6 - x) - 4

y = 18 - 3x - 12

3x + y = 6

This is the equation in rectangular form.

Answer:

radius = 16 inches

C = 32pi or approximately 100.48 inches

Step-by-step explanation:

We know the diameter is twice the radius

d = 2r

32 = 2r

Divide each side by 2

32/2 =2r/2

16 =r

The radius is 16 inches

The circumference is equal to

C = pi * diameter

C = pi *32

C = 32 pi inches

Letting pi  be approximated by 3.14

The circumference is approximately 100.48 in

The radius is 16 inches.

This is because the radius is half the diameter and since we know that the diameter is 32 inches you just have to divide it by 2.

The circumference is 32 pi

This is because the circumference is 2 times pi times radius. This means that is is diameter times pi. This is because we know that that 2 times the radius is equal to the diameter.

Final answer:

The enrollment in the French class compared to the Spanish class is 18/25 as a fraction and 72% as a percent.

Explanation:

To find the enrollment in the French class compared to the Spanish class as a fraction, we need to use the information given that enrollment in French class is 0.72 of enrollment in Spanish class. This means that for every 1 student in the Spanish class, there are 0.72 students in the French class.

To represent this as a fraction, we can write it as 0.72/1 or simply 72/100. Simplifying this fraction gives us 18/25.

To find the enrollment in the French class compared to the Spanish class as a percent, we can convert the fraction 18/25 to a percent. To do this, we divide 18 by 25 and multiply by 100. This gives us 72%.

Answer:

x >4                         or            x < -12/5

Step-by-step explanation:

An absolute value has 2 solutions, a positive and a negative.  Remember to flip the inequality for the negative solution

|5x-4|>16

5x-4 > 16        5x-4 < -16

Add 4 to each side

5x-4 +4> 16+4   or     5x-4+4 < -16+4

5x > 20                or        5x < -12

Divide each side by 5

5x/5 > 20/5          or         5x/5 < -12/5

x >4                         or            x < -12/5

Answer:

Yes, because 2nd picture

Step-by-step explanation:

we know that

If the side lengths of a triangle satisfy the Pythagoras Theorem, then is a right  triangle  

The Pythagoras Theorem states that

[tex]c^{2}=a^{2}+b^{2}[/tex]

where

c is the greater side

a and b are the legs of triangle

we have

[tex]c=70\ ft[/tex]

[tex]a=42\ ft[/tex]

[tex]b=56\ ft[/tex]

substitute

[tex]70^{2}=42^{2}+56^{2}[/tex]

[tex]4,900=4,900[/tex]

therefore

Is a right triangle

Final answer:

Kelsey's porch does form a right triangle because the sum of the squares of the side lengths (42 feet and 56 feet) equals the square of the hypotenuse (70 feet) when applying the Pythagorean Theorem.

Explanation:

To determine if Kelsey's porch forms a right triangle, we need to apply the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the two perpendicular sides (a and b) is equal to the square of the length of the hypotenuse (c).

The formula is a² + b² = c².

For Kelsey's porch, the side lengths are:

Side a = 42 feet

Side b = 56 feet

Side c (potential hypotenuse) = 70 feet

Let's calculate:

42² + 56² = 70²

1764 + 3136 = 4900

4900 = 4900

Since the sum of the squares of the two shorter sides is equal to the square of the longest side, the porch does form a right triangle. The answer is Yes.
