Answer 1

Answer:

t = 9 cm

Step-by-step explanation:

Use Pythagoras' Theorem: a² + b² = c²

(where a and b are the legs and c is the hypotenuse of a right triangle)

Given:

a = 12b = tc = 15a² + b² = c²

⇒ 12² + t² = 15²

⇒ 144 + t² = 225

⇒ t² = 225 - 144

⇒ t² = 81

⇒ t = √81

⇒ t = ±9

⇒ t = 9 only as length is always positive

Answer 2

Solution:

Pythagoras theorem can only be used in:

Right trianglesScalene right trianglesIsosceles right triangles.

Since this is a scalene right triangle, we can use Pythagoras theorem to solve the missing length of the triangle.

=> The formula for Pythagoras theorem is a² + b² = c².

Finding a, b, and c:

Let "a" be 12 cm and "b" be "t" cm."c" is the largest side of the triangle. This means that "c" is 15 cm, as it is the largest side of the triangle.

Setting up the equation:

a² + b² = c²=> 12² + t² = 15²

Simplifying the squares:

=> (12)(12) + t² = (15)(15)

Subtracting (12)(12) both sides:

=> t² = -(12)(12) + (15)(15)=> t² = -144 + 225=> t² = 81

Taking a square root both sides:

=> √t² = √81=> t = ±9

Since the length cannot be negative, the value of t must be positive.

The final answer is...

t = 9

Help plz , math equation !!

Answers

Answer:

We are given the table of a linear function

Since we have to find the equation of the function in the slope-intercept form,

we require the slope as well as the y-intercept

Finding the slope:

We know that slope of a line is Rise / Run

Since from the graph, we notice that the difference of 2 consecutive x-coordinates is 1

Hence, we have the x-coordinates at an interval of 1 and since the slope of a line is defined as the units ascended by the line after covering 1 unit in the x-coordinate

change in y = y[tex]_{n}[/tex] - y[tex]_{n-1}[/tex]       (where n is the number of row in the table)

change in y = 31 - 23

change in y = 8 = Rise

Run = 1 (Since the interval in the table is 1)

Slope = Rise / Run

Slope = 8 / 1

Slope  = 8

Finding the y-intercept:

We need the y-coordinate at x = 0

Going up from the third row, we notice that for every unit decreased in the x-coordinate , 8 units of the y-coordinate are decreased (since the slope =8)

In that case, the y-coordinate of every decreased x-coordinate will be 8 less than the last one

so we can say that the y-coordinate of x = 1 will be 8 less than 23 since x=1 is one less than x = 2

similarly, we can also say that the y-coordinate of x = 0 will be 8 less than (23-8) since x = 0 is one less than x = 1

Therefore, the y-coordinate at x =0

y = (23-8-8)

y-intercept  = 7

Making the Equation:

We need to write the equation in the form:

y = ax + b (where a is the slope of the line and b is the y-intercept)

Replacing the known values, we get

y = 8x + 7

Therefore, the equation of the formula shown in the table is y = 8x + 7

The classical approach to probability requires that the outcomes are​ _______.

Answers

Answer:

Step-by-step explanation:

The classical approach to probability requires that the outcomes are​ equally likely.

Equally likely means the chance or possibility of selection in the sample is equal for them. None is prioritized over the other, all has the equal chance of being selected in the sample.

Given that we are using the classical approach to probability which is based on an assumption that for any procedure having random set of possible outcomes, the possibility of each outcome is equal.

Thus, the classical approach to probability requires that the outcomes are​ equally likely.

Answer:

1 person = 0.75

1 person = 3/4

Step-by-step explanation:

This answer is at best a guess. It seems to me that you are constructing a circle graph, and I would like that confirmed.

The total number of people in the survey is

Total in survey = 96 + 60 + 24 + 96 + 204

Total in survey = 480

A circle contains 360 degrees.

480 people have 360 degrees of circle room

1  person has x degrees of circle room

480 / 1 = 360 / x

Cross multiply

480 x = 360 *1       Divide both sides by 480

x = 360 / 480

x = 0.75

One person takes 3/4 of a degree of the circle.

So the number of people wanting to go to the UK would be

96 * 0.75 = 72 degrees,

For each part of the table, just use what the frequency is for that entry where 96 is now.

If f(x) = 2x and g(x) = 5x, what is f(g(x)) when x = 3?​

Answers

Hey there!

RANDOM FACTOID:

‘‘f(x)’’ or ‘‘g(x)’’ is understood to be “y”


f(x) = 2x

f(x) = 2(3)

f(x) = 2 + 2 + 2

f(x) = 4 + 2

f(x) = 6


Therefore, your answer is: f(x) = 6


g(x) = 5x

g(x) = 5(3)

g(x) = 5 + 5 + 5

g(x) = 10 + 5

g(x) = 15


Therefore, your answer is: g(x) = 15


OVERALL ANSWER: f(x) = 6 or g(x) = 15

The likelihood of an event occurring may be described as being certain, more likely, equally likely, less likely, or impossible

Answers

We will find the probability of getting each color of marble, and we will see that getting red and blue is equally likely, while getting green is less likely.

How to find the probabilities for each color of marble?

If we draw a marble at random from the box, all of them will have the same probability of being drawn.

Then the probability of getting a given color is given by the quotient between the number of marbles of that color and the total number of marbles.

Probability of getting red:

P = 11/25 =  0.44  This is really close to 50%, so this is equally likely.

Probability of getting blue:

P = 11/25 =  0.44  This is really close to 50%, so this is equally likely.

Probability of getting green:

P = 3/25 = 0.12 This is really close to 0%, so this is less likely.
