(3^5-3^4)(3^3+3^2)/24​

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:

[tex]\boxed{\text{[2, 33]}}[/tex]

Step-by-step explanation:

The range is the spread of the y-values (minimum to maximum distance travelled).

The minimum is 2 mi, and the maximum is 33 mi, so the range is from 2 to 33.

In interval notation, the range is [tex]\boxed{\textbf{[2, 33]}}[/tex]

Answer:

31

Step-by-step explanation:

31

The range is the difference between the largest and smallest number.

range = biggest − smallest = 33 − 2 = 31

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%.

Step-by-step explanation:

For this case we must find the value of the following expression:

[tex]\sqrt {678}[/tex]

This expression can not be simplified. Its excata form is the same. On the other hand, if we introduce this expression in a calculator, we find that the decimal form of the expression is: 26.0384

Answer:

Answer:

A: addition property of equality

Step-by-step explanation:

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.

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:

Step-by-step explanation:

You need to notice that when altitude goes up, temperature goes down. That means the correlation is negative.

The table shows the temperature decrease to be monotonic (nowhere does it go up when altitude increases), so the correlation is strong.

The strong negative correlation number available to you is -0.986.

If you want confirmation, you can put the numbers into your favorite graphing calculator and tell it to compute the correlation for you.

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:

A

Step-by-step explanation:

The tenth column value is the first after the decimal point, that is 3

To round the required value of 3

• If the value following 3  ≥ 5, round 3 up to 4

• If the value following 3 < 5 , then leave as 3

Here the value following 3 is 5 so round 3 up to 4

Answer:

Option A

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.

Answer:

A) exponential

Step-by-step explanation:

It is in a curving pattern which indicates exponential. Linear is a straight line.

The best-fitting regression model for the considered data plot is given by: Option A: Exponential.

When the data shows some trend, either linear (making a line), or non-linear (a predictable curve), we fit a mathematical curve on that data set, as a representative of the pattern in that data set, to predict the output based on the inputs.

The considered plot is not forming a straight line(so no linear fitting), but we can see that a smooth curve can be fitted in the considered data. Since the exponential functions' graph approximately goes the same way (for positive exponent, and increasing value of output).

Thus, the best-fitting regression model for the considered data plot is given by: Option A: Exponential.
