The percent decrease from 15 to 12 is 20%

What is percentage ?

Percentage is a way of expressing a proportion or a ratio as a fraction of 100. It is often denoted by the symbol "%". For example, if we say that 20 out of 100 people in a room are wearing a red shirt, we can express this proportion as a percentage by multiplying it by 100:

20/100 x 100% = 20%

To calculate the percent decrease from 15 to 12, we first need to find the difference between the two values:

15 - 12 = 3

Then we divide the difference by the original value (15) and multiply by 100 to get the percent change:

(3/15) x 100 = 20%

Therefore, the percent decrease from 15 to 12 is 20%.

Answer:

Step-by-step explanation:

The greatest difference possible is 0.4

The decimal 0.4 is equivalent to 410 , so 0.4 is located between 0 and 1 . On a number line, divide the interval between 0 and 1 into 10 equal parts and place marks to separate the parts.

The greatest difference possible difference of two decimals to the hundredths place that are between 0 and 1 is 0.99

For us to get the difference possible difference, we will take the difference between the highest values and the lowest values between 1 and 10

Greatest values = 0.99999999999

Possible least value = 0.0000000001

Taking the difference:

Difference = 0.99999999999 - 0.0000000001

Difference = 0.9999999998

Convert to the nearest hundredth place

0.9999999998 to the nearest hundredth is 1.00. Since the value must be between 0 and 1, the required value will be 0.99

y = 4x - 11

Step-by-step explanation:

The general equation of the slope-intercept form of a line is given by:

y = mx + b, where

We can find b, the y-intercept of the line, by plugging in 4 for m and (3, 1) for (x, y) in the slope-intercept form:

1 = 4(3) + b

1 = 12 + b

-11 = b

Thus, the y-intercept is -11.

Thus, the equation of the line with a slope of 4 passing through the point (3, 1) in slope-intercept form is y = 4x - 11

The answer is:

Work/explanation:

First, we will write the equation in point slope:

\(\sf{y-y_1=m(x-x_1)}\)

where m = slope;

Jiri is 12 years old

Step-by-step explanation:

To start off we need to make an equation. Since we know both of their ages add up to 48 and that Pamela's age is 3 times Jiri's age we can say x(Jiri's Age) + 3x(Pamela's age) =48 --> x+3x=48

Now we have the equation x+3x=48, and we need to solve it.

First combine like terms

4x=48

Now divide both sides by 4

x=12

And now since we are using Jiri's age as x we know Jiri is 12 years old.

Answer:

Probability = number of yellow jellybeans / total number of jellybeans

=  24 / 80

=  3/10.

Step-by-step explanation:

Answer:

15%

Step-by-step explanation:

There are 80 total jelly beans, as stated in the question. Therefore, there are 80 "Total Events".

There are 12 yellow jellybeans in the bowl. Therefore, there are 12 preferred events, since the question asks the probability of pulling one yellow jellybean randomly.

\(\frac{\text{Preferred Events}}{\text {Total Events}} =\frac{12}{80}\)

I do not know what form the question prefers, so I did the probability in all forms.

Divide 12 by 80.

\(12/80 = 0.15\)

There is a 0.15 chance that Ricky would pull out a yellow bean.

Divide 12 by 80.

\(12/80=0.15\)

Convert into a percent. Multiply 0.15 by 100.

\(0.15*100=15\)

There is a 15% chance that Ricky would pull out a yellow bean.

Simplify 12/80.

\(\frac{12/2}{80/2} =\frac{6/2}{40/2} =\frac{3}{20}\)

There is a \(\frac{3}{20}\) chance that Ricky would pull out a yellow bean.

Unit rates are special ratios that help describe rates of time or price.

Defining Unit Rates

Unit rate is the rate per one quantity. For example, the question tells us the rate at which Alexander caught lightning bugs in 7 minutes. So, the unit rate would be the number of bugs caught in one minute. Unit rates are most commonly used for time and price. Another example of a unit rate is the price of apples per pound. Just as 21:7 is a ratio, unit rates can be written as a ratio.

Finding the Unit Rate

The easiest way to find the unit rate is through division. We want to find the rate per 1 minute. Since the current rate is given per 7 minutes, we need to divide both values by 7.

This means that the unit rate is 3 lightning bugs per 1 minute.

According to the z-score distribution table, we find out that the p-value is 0.0752 for the given test statistic of z = 1.438 which is accurate to four decimal places.

It is given to us that -

A study is conducted to see if the probability of catching the flu this year is significantly more than 0.23

The sample data produces the test statistic

The value of z = 1.438

We have to find out the p-value accurate to four decimal places.

We know that the p-value is known as the decimal value which can be expressed from 0 to 100%. This p-value is important in hypothesis testing in order to establish the significance of the results expected.

We are given that the test statistic, z = 1.438 and we know that this is a two-tailed test.

So, we can obtain the p-value from the z distribution table.

P-value = 2P (Z<1.438)

=> P-value = 0.0752       [Value from z-score table]

Thus, from the z-score distribution table, we find out that the p-value is 0.0752 which is accurate to four decimal places.

height of the candle after 6 hours= 18.6 centimeters

Step-by-step explanation:

the function gives a line with a slope of −0.4.

the height of the candle after 11 hours is 16.6 centimeters.

after 6 hours, the height will be

But slope= y2-y1/x2-x1

Y2 is the unknown

Y1 = 16.6

X1= 11 hours

X2= 6 hours

y2-y1/x2-x1= -0.4

(Y2-16.6)/(6-11)= -0.4

(Y2-16.6)/(-5)= -0.4

(Y2-16.6)= -5( -0.4)

(Y2-16.6)= 2

Y2 = 2+16.6

Y2 = 18.6 centimeters

height of the candle after 6 hours= 18.6 centimeters

The required, general solution for x that satisfies the equation cos(x + 30) = -1 is x = (2n + 1)π - 30.

To find the general solution for the equation cos(x + 30) = -1, we can start by considering the general form of the cosine function. The cosine function has a period of 2π, meaning it repeats every 2π radians.

In this equation, we have cos(x + 30) = -1. Since the cosine function has a maximum value of 1 and a minimum value of -1, the only way for cos(x + 30) to equal -1 is if x + 30 is an odd multiple of π. We can write this as:

x + 30 = (2n + 1)π

Here, n is an integer representing the number of periods of the cosine function. To find the general solution, we can solve for x by subtracting 30 from both sides:

x = (2n + 1)π - 30

This equation gives us the general solution for x that satisfies the equation cos(x + 30) = -1. We can see that for each integer value of n, we have a different solution.

Answer:

The probability that if Sunday is sunny, then Tuesday is also sunny is 0.86.

Step-by-step explanation:

Let us denote the events as follows:

Event 1: a sunny day

Event 2: a rainy day

From the provided data we know that the transition probability matrix is:

                 \(\left\begin{array}{ccc}1&\ \ \ \ 2\end{array}\right\)

\(\text{P}=\left\begin{array}{c}1&2\end{array}\right\)  \(\left[\begin{array}{cc}0.90&0.10\\0.50&0.50\end{array}\right]\)

In this case we need to compute that if Sunday is sunny, what is the probability that Tuesday is also sunny.

This implies that we need to compute the value of P₁₁².

Compute the value of P² as follows:

\(P^{2}=P\cdot P\)

     \(=\left[\begin{array}{cc}0.90&0.10\\0.50&0.50\end{array}\right]\cdot \left[\begin{array}{cc}0.90&0.10\\0.50&0.50\end{array}\right]\\\\=\left[\begin{array}{cc}0.86&0.14\\0.70&0.30\end{array}\right]\)

The value of P₁₁² is 0.86.

Thus, the probability that if Sunday is sunny, then Tuesday is also sunny is 0.86.

8 halls would be required to accommodate 520 people in the hall.
