Given : The probability of a hurricane being within 100 miles of a location in two days is 40%.

Event : " Hurricane being within 100 miles of a location in two days "

Clearly, 40% < 50%.

Angle 1 and angle 2 are supplementary angle. Then the measure of the angle 1 is 25°.

Two angles are said to be supplementary angles if their sum is 180 degrees.

If angle 2 measures 155 degrees in the image below.

Angle 1 and angle 2 are supplementary angle.

  ∠1 + ∠2 = 180°

∠1 + 155° = 180°

          ∠1 = 25°

Step-by-step explanation:

then, x-axis

then, 3

Triangle 1 is the image of triangle 2 reflected over the y-axis

Triangle 2 is the image of triangle 3 reflected over the x-axis.

Reflecting triangle 4 over the y-axis results in triangle 3.

A triangle is a three-sided polygon It is one of the most fundamental geometric forms.

Triangle 1 is on the opposite side of triangle 2. When the triangles are bisected, they contact the y-axis.

Triangle 2 is to the left of triangle 3. Triangle 3 is to the right of triangle 2. When the triangles are bisected, they contact the x-axis.

You may build the same form by "mirroring" triangle 4 across the y-axis, then rotating it 90 degrees and placing it at the same distance from the y-axis.

Hence, triangle 1 is the y-axis reflected image of triangle 2, triangle 2 is the x-axis reflected image of triangle 3, and triangle 3 is formed by reflecting triangle 4 over the y-axis.

Answer:

A) mean = 1.2

B) median

C) The measures of center use data points to approximate a middle value or average of a given data set

Step-by-step explanation:

The “balance” process was developed to provide another way in which the mean characterizes the “center” of a distribution. 

The mean is the balance point of the data set when the data are shown as dots on a dot plot (or pennies on a ruler). 

A) The balance point for the points 0.4, 1.4, and 1.8. Will be

(0.4 + 1.4 + 1.8)/3 = 3.6/3 = 1.2

B) The median is the measure of center that is indicated by the center of balance

The median is the value in the center of the data. Half of the values are less than the median and half of the values are more than the median. It is probably the best measure of center to use in a skewed distribution.

C) A measure of central (measure of center tendency) is a value that describe a set of data by identifying the central position of the data set. The three measures of central tendency are the mean, median and mode.

The question involves using the quadratic formula where a=1, b=0.0211, and c=-0.0211 to find the two possible values for d.

To solve for the values of a, b, c, and d using the given information, we can identify the quadratic formula, which is expressed as:

x = (-b ± √(b² - 4ac)) / (2a)

Given that a = 1, b = 0.0211, and c = -0.0211, we can substitute these into the formula to find the value for x, which could represent d in this case:

x = -0.0211 ± √(0.0211² - 4(1)(-0.0211)) / 2(1)

This simplifies to:

x = -0.0211 ± √(0.00044421 + 0.0844) / 2

From this, we can calculate the two possible values for d.

2. See Explanation Below

Step-by-step explanation:

Given

Allison

[tex]Morning: 2\frac{7}{8} miles[/tex]

[tex]Afternoon: 3\frac{3}{8} miles[/tex]

Total: About 6 miles

Jennifer

[tex]Morning: 3\frac{1}{10} miles[/tex]

[tex]Afternoon: 3\frac{3}{10} miles[/tex]

Total: [tex]6\frac{4}{10} miles[/tex]

Required

How their answers differ

To understand how their answers differ; first we need to calculate the actual miles they both ran.

Total = Distance covered in the morning + Distance covered in the evening

For Allison

Total Distance = [tex]2\frac{7}{8} + 3\frac{3}{8}[/tex]

Convert mixed fractions to improper fractions

Total Distance = [tex]\frac{23}{8} + \frac{27}{8}[/tex]

Take LCM and add

Total Distance = [tex]\frac{23 + 27}{8}[/tex]

Total Distance = [tex]\frac{50}{8}[/tex]

Total Distance = 6.25 miles

For Jennifer

Total Distance = [tex]3\frac{1}{10} + 3\frac{3}{10}[/tex]

Convert mixed fractions to improper fractions

Total Distance = [tex]\frac{31}{10} + \frac{33}{10}[/tex]

Take LCM and add

Total Distance = [tex]\frac{31 + 33}{10}[/tex]

Total Distance = [tex]\frac{64}{10}[/tex]

Convert to improper fraction

Total Distance = [tex]6\frac{4}{10} miles[/tex]

From the calculation above, the total distance ran by Allison is 6.25 miles and she said she ran about 6 miles; This means that she approximated the total distance she covered.

Also from the calculation above, the total distance ran by Jennifer is [tex]6\frac{4}{10} miles[/tex] and she said she ran [tex]6\frac{4}{10} miles[/tex]; This means that she gave the actual distance she ran.

Hence, their answers differ because of approximation

Why they are both correct?

As mentioned above, the difference in their answer is approximation.

Approximation is rightly allowed in measurements as long as one is giving the right approximated value.

For Allison; the approximation of 6.25 miles is 6 miles;

For Jennifer; she gave the actual distance she ran ([tex]6\frac{4}{10} miles[/tex])

Base on this, we can conclude that both are correct

Step-by-step explanation:

Well it was a lucky guess but the answer is 75

The value of c that makes the vertex the same is 75.

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The vertex of the function f(x) = 2x² + bx + c has an x-coordinate given by

-b/2a, where a = 2 is the coefficient of the x² term.

The x-coordinate of the vertex is x = -b/4.

To find the y-coordinate of the vertex, we can substitute this value of x into the function f(x) and simplify:

f(-b/4)

= 2(-b/4)² + b(-b/4) + c

= b²/8 - b²/4 + c

= -b²/8 + c

We want the vertex of the new function to be the same as the vertex of f(x), so the x-coordinate of the vertex should still be -b/4.

This means that the new function must have the form

g(x) = 2x² + bx + d, where d is a constant.

We want the y-coordinate of the vertex of g(x) to be the same as the y-coordinate of the vertex of f(x), which is -b^2/8 + c.

Therefore, we must have:

g(-b/4) = -b²/8 + c

Substituting the form of g(x) and simplifying:

2(-b/4)² + b(-b/4) + d = -b²/8 + c

Simplifying further:

-b²/8 + d = -b²/8 + c

d = c

This shows that the value of d (the constant term in the new function g(x)) must be the same as the value of c (the constant term in the original function f(x)) in order for the vertex of the new function to be the same as the vertex of f(x).

Therefore,

The value of c is 75.

The tiger population loses approximately 3/5 of its size every 97.14 decades.

The rate of change in the tiger population can be determined by examining the equation N(t) = 710(35). The coefficient of 35 represents the exponential growth factor of the population, which can be interpreted as the population multiplying by 35 over each time period.

To determine the rate of change in terms of the percentage size lost, we can calculate the fractional change by subtracting 1 from the growth factor. In this case, 35 minus 1 equals 34. The percentage size lost can then be calculated by dividing the fractional change by the growth factor and multiplying by 100, giving us (34/35) x 100 = 97.14%.

Therefore, the tiger population loses approximately 3/5 of its size every 97.14 decades.

correct option is B) log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w)

Step-by-step explanation:

Here we need to simplify a logarithmic expression and find which expression is equivalent to it . Let's find out:

We have ,

log Subscript 12 Baseline (StartFraction one-half Over 8 w EndFraction) or ,

⇒ [tex]Log_1_2(\frac{\frac{1}{2} }{8w} )[/tex]

We know that : [tex]Log(\frac{a}{b} )=Log(a)-Log(b)[/tex]

⇒ [tex]Log_1_2(\frac{1}{2}) - Log_1_2(8w)[/tex]

We know that : [tex]Log(ab) = Log(a)+Log(b)[/tex]

⇒ [tex]Log_1_2(\frac{1}{2}) -( Log_1_2(8)+Log_1_2(w))[/tex]

Therefore , correct option is B) log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w)

The expression that could be considered equivalent to logSubscript 12 Baseline (StartFraction one-half Over 8 w EndFraction would be:

B). log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w) or  [tex]Log_{12}(\frac{1}{2}) - (Log_{12}(8) + Log_{12}(w))[/tex]

Given that,

[tex]Log_{12} (\frac{1/2}{8w} )[/tex]

Using the expression,

[tex]Log({\frac{a}{b}) = Log (a) - Log(b)[/tex]

We get,

[tex]Log_{12} (\frac{1/2}{8w} )[/tex]

[tex]= Log_{12}(\frac{1}{2}) - Log_{12} (8w)[/tex]

Using expression [tex]Log(ab) = Log(a) + Log(b)[/tex]

∵ [tex]Log_{12}(\frac{1}{2}) - (Log_{12}(8) + Log_{12}(w))[/tex]
