Answer:

3:25

Step-by-step explanation:

The photo shows how it's solved.

Answer: 3:25

Step-by-step explanation:

Step 1) Convert the decimal number to a fraction by making 0.12 the numerator and 1 the denominator

0.12 = 0.12/1

Step 2) Multiply the numerator and denominator by 100 to eliminate the decimal point.
0.12 x 100

------------ = 12/100
1 x 100

Step 3) Simplify the fraction in the previous step by dividing the numerator and the denominator by the greatest common factor (GCF) of 12 and 100. (The GCF of 12 and 100 is 4.)

12 ÷ 4

---------  = 3/25  

100 ÷ 4

Step 4) Convert the fraction in the previous step to a ratio by replacing the divider line with a colon like this:  

3  

25   =  3:25

Based on the distance that Jill is above sea level, and the distance of the whale, the difference in elevation is 1.35 km.

Jill's elevation relative to sea level is:

= +5/4 km

The whale's elevation relative to sea level is:

= - 0.1 km

The difference is therefore:

= 5/4 - (-0.1)

= 1.25 + 0.1

= 1.35 km

Answer:

y = 5/3 x + 4

Step-by-step explanation:

To find the inverse, interchange the x and y variables and solve for y. (that might sound a bit confusing, but don't worry! :)

Our current function is f(x) = 3/5 (x-4). Let's make f(x) = y, so the function is y = 3/5 (x - 4).

Now, switch the x and y variables. x = 3/5 (y - 4).

Now, just solve for y!

x = 3/5 y - 12/5

5x = 3y - 12

5x + 12 = 3y

3y = 5x + 12

y = 5/3 x + 4

Answer:

Step-by-step explanation:

Then 1 - 3/5 = 2/5. This means that 2/5 of the frogs in that particular part of the rainforest are not poisonous. This fraction can also be expressed as 40/100 or 0.4 in decimal form.

In the given scenario, we know that 3/5 of the frogs in a particular part of the rainforest are poisonous. This means that the remaining fraction of the frogs are not poisonous.

To find this fraction, we need to subtract 3/5 from 1 (since the sum of the fractions of poisonous and non-poisonous frogs is equal to 1).

It's important to note that just because a frog is not poisonous, it doesn't mean it's safe to touch or handle them. It's always best to admire these beautiful creatures from a safe distance and leave them alone in their natural habitat.

Rounded to the nearest hundredth, the value of y at \(x = 7\) is approximately \(12.78\), according to the concept of linear regression line.

To find the linear regression line for the given data, we can use statistical software or a calculator. The equation of the linear regression line is of the form \(y = mx + b\), where m represents the slope and b represents the y-intercept.

Using the provided data, the linear regression line equation is:

\(\[ y = 1.3642x + 3.2324 \]\)

To find the value of \(y\) at \(x = 7\), we substitute \(x = 7\) into the equation:

\(\[ y = 1.3642(7) + 3.2324 \]\)

Simplifying the equation, we get:

\(\[ y = 9.5494 + 3.2324 \]\[ y = 12.7818 \]\)

In conclusion, the linear regression analysis allows us to determine the relationship between the variables x and y in the given data set. By finding the equation of the linear regression line, we can estimate the value of y for any given x. In this case, the linear regression line equation is \(y = 1.3642x + 3.2324\). By substituting \(x = 7\) into the equation, we find that the estimated value of y is approximately \(12.78\). This analysis provides a useful tool for predicting and understanding the relationship between variables, allowing us to make informed decisions and interpretations based on the data.

Answer:

t = 35.13

Step-by-step explanation:

Simplifying

62.52 = 27.39 + t

Solving

62.52 = 27.39 + t

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '-1t' to each side of the equation.

62.52 + -1t = 27.39 + t + -1t

Combine like terms: t + -1t = 0

62.52 + -1t = 27.39 + 0

62.52 + -1t = 27.39

Add '-62.52' to each side of the equation.

62.52 + -62.52 + -1t = 27.39 + -62.52

Combine like terms: 62.52 + -62.52 = 0.00

0.00 + -1t = 27.39 + -62.52

-1t = 27.39 + -62.52

Combine like terms: 27.39 + -62.52 = -35.13

-1t = -35.13

Divide each side by '-1'.

t = 35.13

t = 35.13

Step-by-step explanation:

For the first one use the law of total probability

B=A∩B+A'∩B

12=9+A∩B

A∩B= 3

For this one you should use demorgans law and the union formula

(A'∩B')=(AUB)'

AUB= A+B-A∩B

6+12-3=15

15'= 24-15 = 9

(A'UB')=(A∩B)'

(A∩B)'= 24-A∩B= 24-3= 21

The transformation of the function G(x) in the form of y = +A| x - C| + D is -

y = 0.5| x + 1| + 0.5

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

To write the transformation of the function G(x) = 0.5|x+1| in the form y = +A |x - C| + D, we need to find the values of A, C, and D.

First, let's rewrite the given function in the form of |x - C| -

G(x) = 0.5 | x + 1| = 0.5| x - (-1)|

Comparing with the standard form y = A | x - C| + D, we have -

A = 0.5, C = -1

To find the value of D, we need to substitute a point on the graph of G(x) into the function and solve for D.

Let's use the point (-2, 1) -

G(-2) = 0.5|-2+1| = 0.5

So, we get D = 0.5.

Therefore, the transformation of the function is y = 0.5| x + 1| + 0.5.

Therefore, the math expression for the time taken is:

time = 186 m ÷ (735 km/h × 1000 m/km ÷ 3600 s/h) = 186 m ÷ 205 m/s = 0.9073 s

Speed is a measure of how fast an object is moving relative to a reference point. It is defined as the distance traveled by an object in a given amount of time. The standard unit of measurement for speed is meters per second (m/s) in the metric system, but it can also be measured in miles per hour (mph), kilometers per hour (km/h), or other units depending on the context.

Given by the question.

We can use the formula:

distance = speed × time

To find the time taken to cover a distance of 186 m at a speed of 735 km/h, we first need to convert the speed to meters per second (m/s).

1 km = 1000 m

1 h = 3600 s

So,735 km/h = (735 × 1000) m/ (3600 s) = 205 m/s

Now, we can plug in the values into the formula:

186 m = 205 m/s × time

Solving for time, we get:

time = 186 m ÷ 205 m/s = 0.9073 s

The fourth term a₄ of the sequence is 29933

From the question, we have the following definition of the function that can be used in our computation:

a₁= 3

aₙ = (aₙ₋₁)² + 4

The above definitions imply that we simply square the previous term and then add 4 to the squared result to get the current term

Using the above as a guide,

so, we have the following representation

a₂ = (3)² + 4

a₂ = 13

Also, we have

a₃ = (13)² + 4

a₃ = 173

Lastly, we have

a₄ = (173)² + 4

Evaluate the equation

a₄ = 29933

Hence, the value of a₄ is 29933

Given that:

M1 = 0.10 M

The correct answer is, by choosing a = -2 and b = 1, we satisfy both inequalities .a < b:

To make both inequalities true, we need to select values for a and b that satisfy the given conditions:

a < b: This inequality means that the value of a should be less than the value of b.

|b| < |a|: This inequality means that the absolute value of b should be less than the absolute value of a.

One possible solution that satisfies both conditions is:

a = -2

b = 1

With these values, we have:

-2 < 1 (a < b)

|-1| < |2| (|b| < |a|)

Therefore, by choosing a = -2 and b = 1, we satisfy both inequalities.a < b:

This inequality states that the value of a should be less than the value of b. In other words, a needs to be positioned to the left of b on the number line. To satisfy this condition, we can choose a to be any number that is less than b. In the example I provided, a = -2 and b = 1, we can see that -2 is indeed less than 1, fulfilling the requirement.

|b| < |a|:

This inequality involves the absolute values of a and b. The absolute value of a number is its distance from zero on the number line, always resulting in a non-negative value. The inequality states that the absolute value of b should be less than the absolute value of a. To satisfy this condition, we can choose b to be any number with a smaller absolute value than a. In the example I provided, |1| is less than |(-2)|, as 1 is closer to zero than -2, fulfilling the requirement.

By selecting a = -2 and b = 1, we satisfy both inequalities: a < b and |b| < |a|. The specific values of -2 and 1 were chosen as an example, but there are multiple other values that would also satisfy the given conditions. The important aspect is that a is indeed less than b, and the absolute value of b is smaller than the absolute value of a.
