Like asking what measures distance between a lake and a city.

Answer:

(0,12)

Step-by-step explanation:

Just plug in 0 for x so (0-6)(0-2) = 12 so that's the y value.

Also, a y intercept has to be of the form (0,y) where y is some number.  The x value has to be 0, so that eliminates the last two options automatically, but if we put the x and y value we got together we get (0,12)

Answer:

(0,12)

Step-by-step explanation:

[tex]f(x) = (x - 6)(x - 2)[/tex]

To find out y intercept , plug in 0 for x and find out f(0)

y intercept are the value where the graph crosses y axis

[tex]f(x) = (x - 6)(x - 2)[/tex]

[tex]f(0)= (0-6)(0 - 2)=12[/tex]

When x is 0 the value of y is 12

Write y intercept as (0,y) that is (0,12)

Answer: [tex]\frac{1}{4}=2^{(-2)}[/tex]

Step-by-step explanation:

You know that an expression written is logarithmic form is:

[tex]x=log_b(y)[/tex]

And an expression equivalent to the expression above that is written in exponential form is:

[tex]y=b^x[/tex]

Therefore, keeping the information above on mind, you have that an equivalent exponential equation for [tex]log_{2}(\frac{1}{4}) =-2[/tex] , is the shown below:

[tex]\frac{1}{4}=2^{(-2)}[/tex]

Answer:

[tex]\frac{1}{4} =2^{-2}[/tex]

Step-by-step explanation:

We are given the following expression and we are to write an equivalent exponential equation for it:

[tex] log_2 (\frac { 1 } { 4 } ) = - 2 [/tex]

We know that the standard form of a logarithmic expression is given by:

[tex] y = log_a ( x ) [/tex]

which is equivalent to the exponential form [tex] x = a ^ y [/tex].

Therefore, for the given expression, the equivalent exponential equation will be:

[tex] \frac { 1 } { 4 } = 2 ^ { - 2 } [/tex]

Answer:

180°

Step-by-step explanation:

The measures of the angles in the triangle shown are ...

81.87°, 60.26°, 37.87°

The sum of those measures is ...

81.87° + 60.26° + 37.87° = 180.00°

Answer:

A) F or G = {5, 6, 7, 8, 9, 10, 11, 12}; B) P(F or G) = 8/12 = 0.667

Step-by-step explanation:

The outcomes in event F are 5, 6, 7, 8 and 9.  The outcomes in event G are 9, 10, 11 and 12.  This means that the event F or G, containing all elements of both events, will be

{5, 6, 7, 8, 9, 10, 11, 12}.  Note that we do not count 9 twice; it only appears in the sample space once.  There are 8 elements out of 12 total in the sample space; this means the probability is 8/12 = 0.667.

Using the addition rule, we begin with P(F).  There are 5 elements in this event; this makes P(F) = 5/12.  

For P(G), there are 4 elements in G; this makes P(G) = 4/12.

To add them, we add P(F) and P(G) but then must take out the element counted twice; this gives us

5/12+4/12-1/12 = 9/12-1/12 = 8/12 = 0.667.

We have that

From the question we are told

a)

Generally

The P(F or G) by counting the number of outcomes in F or G is

F&G={5, 6, 7, 8, 9, 10, 11, 12}

b)

P(F or G) using the general addition rule

[tex]P(FG)=\frac{N_f}{N_g}\\\\P(FG)=\frac{8}{12}[/tex]

[tex]P(FG)=0.667[/tex]

c)

Generally Using addition Rue to attain P(F or G) we have

For P(F or G)

[tex]P(F or G)=PF+PG-P(F+G)[/tex]

[tex]P(F or G)=5/12+4/12-(1/12)\\\\ P(F or G)=5/12+1/4\\\\ P(F or G)=\frac{8}{12}[/tex]

Which is done by K(eep)C(hange)F(lip)

2/3 * 5/4 = 10/12 = 5/6

N= 5/6

Which of the following sampling techniques is the most likely to produce a random sample, representative sample of all students at a high school?

A. Choosing every 10th name on the student roster

B. Choosing every 10th student arriving in a 9th grade homeroom

C. Choosing the first 100 students who arrive at school

D. Asking students to call a phone number to answer survey questions

Step-by-step explanation:

A random sample is choosing the first 100 students who arrive at school.

There are five types of Sampling Techniques

Random sampling is similar to putting everyone's name into a bowl and drawing out random names. Each element has a chance of being called.

Systematic sampling is easier to do than random sampling. In systematic sampling, the list of elements is "counted off". That is, every kth element is taken.

Convenience sampling is very easy to do, but it is the least effective technique to use. In convenience sampling, data that is easily available is used.

Cluster sampling is accomplished by dividing the population into groups usually geographically. These groups are called clusters or blocks. The clusters are randomly selected, and each element in the selected clusters are used.

Stratified sampling also divides the population into groups called strata. However, this time it is by some characteristic, not geographically.

Option C , i.e. Choosing the first 100 students who arrive at school is an example of Random Sampling.

Answer:

Step-by-step explanation:

Usain Bolt

Part A

d = 200 m

t = 19.30 seconds

r = d/t

r = 200 / 19.30

r = 10. 36

r = 10.4 m/s

Part B

d = 400 meters

t = 43.18 seconds

r = d/t

r = 400/43.18

r = 9.26 m/s

r = 9.3

Not much difference.

Though you have not given us the distance, it was 100 meters. He was the first man to eclipse 9.7 seconds for the 100 meters.

d = 100 m

t = 9.69 seconds

r = 100 meters/9.69 seconds

r = 10.32 m/s

r = 10.3

Answer: Option a.

Step-by-step explanation:

- Divide both sides of the expression by 7.8:

[tex]7.8e^{\frac{x}{3}ln5}=14\\\\\frac{7.8e^{\frac{x}{3}ln5}}{7.8}=\frac{14}{7.8}\\\\e^{\frac{x}{3}ln5}=\frac{14}{7.8}[/tex]

- By definition:

[tex]e^y=x[/tex]→[tex]y=ln(x)[/tex]

Then:

[tex]\frac{x}{3}ln5=ln(\frac{14}{7.8})[/tex]

- Now, you must solve for x.

Then, you obtain:

[tex]xln5=3ln(\frac{14}{7.8})[/tex]

[tex]x=\frac{3ln(\frac{14}{7.8})}{ln5}[/tex]≈[tex]1.0903[/tex]

The volume of Nadya's container, calculated using the formula for the volume of a cylinder and rounded to the nearest cubic centimeter, is 1414 cubic centimeters.

The volume of Nadya's container can be calculated using the formula for the volume of a cylinder, which is V = πr²h, where V represents volume, r represents the radius of the base, and h represents the height. Given that the radius of the container's base is 5 centimeters and the height of the container is 18 centimeters, substituting these values into the formula gives you V = π(5)²(18) = 1413.72 cubic centimeters. Rounded to the nearest cubic centimeter, the volume is 1414 cubic centimeters.

Answer:

18%

Step-by-step explanation:

18% is the percent increase in tuition fees.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, The tuition at a college increased from 50,000 in 2006 to 59,000 in 2007.

From the general formula of percentage change,

percentage change = change in value/original value * 100

In our case,

original value = 50,000

change in value = 59,000 - 50,000

change in value = 9,000

thus,

Percentage change = 9,000/50,000 *100

Percentage change = 18%

Therefore,  the percent increase in tuition fees is 18%.

The measure of angles in a rhombus can be found understanding the properties of a rhombus (i.e., opposite angles are equal and adjacent angles are supplementary) and possibly applying trigonometry in which angles are not aligned in regular horizontal or vertical manner. Specific measurements can be obtained using a protractor.

To find the measure of the numbered angles in the rhombus, you need to understand the geometric properties of a rhombus. The opposite angles of a rhombus are equal, and the adjacent angles are supplementary, meaning they add up to 180 degrees. Further, the diagonals of a rhombus bisect its angles, and they are perpendicular to each other, forming 90-degree angles where they intersect.

Clearly, the exact measures of the angles will depend on the specific information provided about the rhombus in your diagram. Here are some steps on how you might determine these measures:

Answer: 5 km and 25 km

Answer:

Step-by-step explanation:

x + y = 3 can become x = 3-y

we are going to use substitution

now plug x = 3-y into the other equation

2(3-y) + 3y = 4

6-2y+3y = 4

6 + y = 4

subtract 6 from both sides

y = -2

now plug in y back into one of the equations, it doesn't matter which one. I am going to use the x + y = 3 equation

x -2 = 3

x = 5
