what is the proablity of rolling a 3 and landing on heads

Answer:

x = 6

Step-by-step explanation:

first of all, you should know how to do this, this is the basic level of math that students learn in 4th grade.

first you combine like terms (terms that have the same variable)

6 - 2x + 1x = -4x + 18 + 1x

= 6 - 1x = -3x + 18

= 6 = -2x + 18

= -12 = -2x

= 6 = x

∠NKL = 50°

Step-by-step explanation:

A parallelogram consists of two pairs of congruent angles.

So..

Step-by-step explanation:

36 boxes

28 video games per box

That means, we have to multiply 36 by 28 to get the total number of video games.

36 x 28 = 1008

Therefore, 1,008 video games need to be unpacked.

Marjorie must unpack a total of 1008 video games, calculated by multiplying 36 boxes by 28 video games per box.

Marjorie has 36 boxes of video games to unpack, with each box containing 28 video games.

To find out the total number of video games that need to be unpacked, we simply multiply the number of boxes by the number of video games in each box.

The calculation is as follows:

36 boxes × 28 video games per box = 1008 video games

Therefore, Marjorie needs to unpack a total of 1008 video games.

Answer:

x = 47°

Step-by-step explanation:

m∠DPB + ∠BPC = 180° (Definition of a straight line)

Plug in the corresponding numbers and variables to the corresponding places:

x + 133 = 180

Isolate the variable, x. Subtract 133 from both sides:

x + 133 (-133) = 180 (-133)

x = 180 - 133

x = 47

47° is your answer.

~

Answer:

47 degrees

Step-by-step explanation:

DPC = DPB +BPC = 180

-> x + 133 = 180

-> x = 47

Answer:

The person can live at a distance of 113 miles

Step-by-step explanation:

In this question, we are concerned with calculating how far a person live from a radio station and hear its broadcast given that the broadcast covers an area of 40,000 square miles.

Now this question is asking us to calculate the farthest distance from the radio station to the house of the person.

With the radio station being the center, what we are asked to calculate is the radius which is the distance from the center to the edge ( circumference)

Mathematically, the area can be calculated as

A = π * r^2

Here, we have the Area as 40,000 square miles

Thus,

40,000 = π * r^2

r^2 = 40,000/π

r = √(40,000/π)

r = 112.8379

As a whole number r = 113 miles

Answer:

The median of the data set is 11.

Step-by-step explanation:

2, 2, 5, 10, 12, 13, 18, 24

10 + 12 = 22

22 / 2 = 11

The median of the data set is 11.

We have given the data set,

24, 2, 13, 12, 2, 5, 10, 18

We have to find the median

So first arrange the given data set in asending order.

2, 2, 5, 10, 12, 13, 18, 24

The median is the central number of a data set.

There are two number at center that are 10 and 12

So we have to find the mean of this two number.

10 + 12 = 22

22 / 2 = 11

So the median is 11.

Answer:

The central angle is = 3/8  π

Step-by-step explanation:

To calculate the area of the sector, we will follow the steps below;

First write down the formula for calculating the area of a sector.

If angle Ф is measured in degree, then

area of sector = Ф/360   × πr²

but if angle Ф is measured in radians, then

area of sector = 1/2 × r² × Ф

In this case, since we are asked to find the central angle measure of the sector in radians, then we will use the second formula

area = 48π cm²       and radius = 16 cm

area of sector = 1/2 × r² × Ф

  48π              = 1/2 × 16² × Ф

  48π               = 1/2  ×256 × Ф

  48π                = 128×Ф

Divide both-side of the equation by 128

[tex]\frac{48}{128}[/tex] π  =   Ф

Ф  =  [tex]\frac{48}{128}[/tex] π

The right-hand side can be reduced to its lowest term

Ф =  48 ÷  16   /    128  ÷16   π

Ф = 3/8  π

Answer:

t = 29/42

Step-by-step explanation:

in this equation you have to first multiply everything out on the right side. 3500 * 0.06 = 210.

Now you have 145 = 210t

divide by 210 on both sides

145/210 can be simplified to 29/42

so t = 29/42

The area of the triangle is [tex]5x^4 + 4x^3[/tex] square units

Step-by-step explanation:

Given

Shape: Triangle

[tex]Height = 2x^2[/tex]

[tex]Base = 5x^2+4x[/tex]

Required

The area of the triangle

The area of a triangle is calculated as thus;

[tex]Area = \frac{1}{2}(base)(height)[/tex]

By substituting [tex]Height = 2x^2[/tex] and [tex]Base = 5x^2+4x[/tex]; This gives

[tex]Area = \frac{1}{2}(5x^2 + 4x)(2x^2)[/tex]

[tex]Area = \frac{(5x^2 + 4x)(2x^2)}{2}[/tex]

[tex]Area = (5x^2 + 4x)(x^2)[/tex]

Open Bracket

[tex]Area = 5x^2 * x^2 + 4x * x^2[/tex]

[tex]Area = 5x^4 + 4x^3[/tex]

Hence, the area of the triangle is [tex]5x^4 + 4x^3[/tex] square units

The correlation between the z-scores for X and z-scores for Y is given by: Option A: 0.92

The correlation coefficient(for two variables) is independent of the change of origin and scale of any or both variables.

Thus, we get:

[tex]Corr(X, Y) = Corr\left(\dfrac{X - a}{b}, Y\right) = Corr\left(X, \dfrac{Y - c}{d}\right) = Corr\left(\dfrac{X - a}{b},\dfrac{Y - c}{d}\right)[/tex]

where a, b, c and d are constants.

Suppose the considered random variable be X.

Then, we get the z-scores for X as:

[tex]Z = \dfrac{X - \mu}{\sigma} = \dfrac{X - E(X)}{\sqrt{E(X^2) - [E(X)^2]}}[/tex]

where [tex]\mu = E(X)[/tex] and [tex]\sigma = \sqrt{Var(X)}[/tex] (both are constants).

For this case, we're specified that:

The correlation coefficient for the z-scores of X and Y would be:

[tex]Corr\left(\dfrac{X -\mu_X}{\sigma_X}, \dfrac{Y - \mu_Y}{\sigma_Y}\right)[/tex]

Using the property that origin and scale change doesn't affect correlation coefficient, we get:

[tex]Corr\left(\dfrac{X -\mu_X}{\sigma_X}, \dfrac{Y - \mu_Y}{\sigma_Y}\right) = Corr(X,Y) = 0.92[/tex]

Thus, the correlation between the z-scores for X and z-scores for Y is given by: Option A: 0.92

https://brainly.com/question/10725272

The correct answer to the question is option a) 0.92.

Formula for finding z score is:

where [tex]\mu[/tex] = E(X) and [tex]\sigma[/tex] = √(Var(X)) (both are constants).

We are provided with following information:

Corr(X,Y) = 0.92

Origin &  scale change does not affect correlation coefficient between two scores, so get:

If the correlation between two scores X and Y is 0.92, and both scores are converted to z-scores, the correlation remains unchanged.

This is a property of correlation coefficients, as they are invariant under linear transformations such as converting raw scores to z-scores.

Therefore, the correlation between the z-scores for X and z-scores for Y would be 0.92.

The correct answer is option a) 0.92.

Answer:

29/50

Step-by-step explanation:

To solve this expression, we first have to make sure that the denominators are equal. If the denominators aren't equal, we can't add the fractions together. To make equivalent denominators, the easiest way is to find the LCM. Looking at these two fractions, we see that the LCM is 100. To get to 100 from 10 in the first fractions denominator we multiply by 10. Since we multiplied by 10 in the denominator, we must multiply by 10 in the numerator, leaving us with the fraction:

5/10 = 50/100

Since the denominators are now equal, we can add these two fractions:

50/100 + 8/100 = 58/100 = 29/50

Adding two fractions equal

[tex]\frac{5}{10}+ \frac{8}{100}=\frac{29}{50}[/tex]

To add any two fractions , the denominators should be same.

LCD is  the smallest number of all the common multiples of the given denominators

We need to add [tex]\frac{5}{10}+ \frac{8}{100}[/tex]

To add two fractions, we need to make the denominators same

multiples of 10 are 10,20,30,40,50,60,70,80,90,100......

multiples of 100 are 100,200, 300, 400 .......

Common multiple is 100. so LCD is 100

[tex]\frac{5}{10}+ \frac{8}{100}\\\\\frac{5 \cdot 10}{10 \cdot 10}+ \frac{8}{100}\\\\\frac{50}{100}+ \frac{8}{100}\\ \frac{50+8}{100}\\\\\frac{58}{100}\\\\\frac{29}{50}[/tex]

Adding two fractions,

[tex]\frac{5}{10}+ \frac{8}{100}=\frac{29}{50}[/tex]

The value of the power in the expression 5^4 is 625. This is found by multiplying the base (5) by itself 4 times, which is the exponent.

The value of the power is 54. This is because 54 is the base of the expression raised to the exponent 4. In other words, 54 is multiplied by itself 4 times.

Identify the base: The base is the number that is being raised to the power. In this case, the base is 5.

Determine the exponent: The exponent is the small number written above and to the right of the base. In this case, the exponent is 4.

Write the expression in expanded form: The expanded form of the expression is 5 x 5 x 5 x 5.

Evaluate the expression: 5 x 5 x 5 x 5 = 625.

Therefore, the value of the power is 625.
