Answer:

0.8116

Step-by-step explanation:

From the frequency distribution table given

Total Number of voters = 6.4 + 10.4 + 20.2 + 24.3 + 51.1 + 26.1 = 138.5 Million

Number of Voters 65 or Older = 26.1 million

\(P($that a voter chosen at random is 65 or older) = \dfrac{26.1}{138.5}\\$Therefore:\\P(that a voter chosen at random is NOT 65 or older)$ \\= 1- \dfrac{26.1}{138.5}\\\\=0.8116\)

Denis's and Dasha's methods use different operations to simplify the expressions in different orders.

Denis's method uses addition, subtraction, and multiplication operations, but Dasha's method does not.

Multiplication operations are described as using mathematical operation that indicates how many times a number is added to itself.

Denis's Assignment

2* 6+2w-54

12+2w = 54

12-12+2w= 54-12

2w=42

w= 21  

Dasha's Assignment

54-2* 6

54-12= 42

The two widths add to 42 cm

42/ 2-21

We can see that Dasha's method also uses addition and subtraction operations, but she simplifies the expression by performing the operations in a different order.

She subtracts the product of 2 and 6 from 54.

Answer:

Sample space = 27 possible outcomes

a) P(just one red) = 4/9

b) P(at least one red) = 19/27

Step-by-step explanation:

Each die has 3 possible outcomes (red, blue or yellow), so the sample space of the number of possible outcomes for rolling three dice is 3^3 = 27

a)

The probability of the face up color being red is 2/6 = 1/3, and the probability of it not being red is 4/6 = 2/3.

The die with the face up red can be any of the three dice, so we also need to multiply the probabilities by a combination of 3 choose 1. So the final probability is:

P = C(3,1) * (1/3) * (2/3)^2 = 3 * (1/3) * (4/9) = 4/9

b)

To find the probability of at least one face up being red (event A), we can find the probability of the complementary case, that is, no one of the three die being face up red (event A'), and then we calculate P(A) + P(A') = 1.

In the case where no face up are red, we have the probability of 2/3 for each die, so we have:

P(A') = (2/3)^3 = 8/27

Then we can find P(A):

P(A) = 1 - 8/27 = 19/27

The store that has a better deal on DVDs is Store A.

The amount more that Sheila will save from buying from the store with the better deal is $ 1.00.

The store with the better deal is the store that has a lower price per unit of DVDs.

Price per unit of DVD in store A:

= Cost of DVD / Number of DVDs

= 9.45 / 3

= $3.15

Price per unit of DVD in Store B :
= 12.80 / 4

= $ 3.20

Store A therefore has the better deal and the amount that Sheila will save from 20 DVDs is :

= ( 3.20 x 20 ) - ( 3.15 x 20)

Answer:

The equation of the parallel  line to the given equation is

3 x-4 y = -4    and

The equation of the parallel  line to the given equation is

\(y = 1 + \frac{3 x}{4}\)

Step-by-step explanation:

Explanation:-

Given equation of the line 3 x -4 y = 7 and given point ( -4 , -2 )

The equation of the parallel line to the given equation is

3 x - 4 y = k

it is passes through the point ( -4 , -2)

3 (-4) - 4 ( -2) = k

-12 +8 = k

k = -4

The equation of the parallel  line to the given equation is

3 x- 4 y = -4

Dividing '4' on both sides , we get

\(\frac{3 x-4 y}{-4} = 1\)

\(\frac{-3 x}{4} +y =1\)

\(y = 1 + \frac{3 x}{4}\)

Conclusion:-

∴ The equation of the parallel  line to the given equation is

3 x- 4 y = -4

and

The equation of the parallel  line to the given equation is

\(y = 1 + \frac{3 x}{4}\)

Step-by-step explanation: i juss subtracted

The elevation of mountain mt.kenya is, x = 17,057.1 feet by substitution method from the elevation of mountain K2 given.

Given that,

K2 is 11,194.21 feet higher than mt.Kenya, write and solve an equation to find the elevation of mt.Kenya.

x = mt. Kenya ( since given that x represents the elevation of mt.kenya)

Let us consider/assume ,

y = K2 (say)

Therefore, the relation between x and y:

                   x = y - 11,194.21    ( or )

                   y = x + 11,194.21  

( since given that K2 is 11,194.21 more than mt.Kenya )

The elevation of K2 Mountain = 28251.31 feet

                                                  = y

substitute the value of y in x = y - 11,194.21

                                            x = 28251.31 - 11,194.21

                                       ∴ x = 17,057.1 feet.

Therefore the elevation of mt.kenya found to be, x = 17,057.1 feet by substitution method.

Answer:

  B. The graph of K has a greater y-intercept

  D. The graph of J has a greater slope.

Step-by-step explanation:

Given a table for function J and an equation for function K, you want to know which has the greater slope, and which has the greater y-intercept.

The y-intercept is the value of the function when x=0. We see from the table that y=2 corresponds to x=0 for function J.

We see from the equation for function K that the constant is 8. This is the value of y when x=0.

Function K has the greater y-intercept (8 vs. 2).

The slope is the change in y-value when x increases by 1 unit. We see from the table that y=7 when x=1, so the change in y from x=0 to x=1 is 7-2 = 5. The slope of function J is 5.

The equation for function K has an x-coefficient of 3. This means a change in x of 1 unit will result in a change in y of 3 units. The slope of function K is 3.

Function J has the greater slope (5 vs. 3).

Additional comment

Both functions are graphed in the attachment. The y-intercepts have their points labeled. The graph with the steeper slope is the blue line, function J.

The scatter plot shows Madeline's test scores on math exams, y, when she studies x hours. There is a positive association between hours studied and test scores.

What is the short definition of a scatter plot?

A scatter plot is a collection of dots that have been plotted along a horizontal and vertical axis.

                   In statistics, scatter plots are crucial because they can demonstrate the degree of correlation, if any, between the values of observed quantities or occurrences (called variables).

What is the purpose of a scatter plot?

Data points are plotted on a horizontal and vertical axis using scatter plots in an effort to demonstrate the degree to which one variable is influenced by another.

                    A marker is used to represent each row in the data table, and the position of the marker depends on the values of the columns that are set up on the X and Y axes.

There is a positive association between hours studied and test scores.

As the hours increase, you see the test scores rising.
