He doesn't have enough storage space remaining to add a rock playlist that uses that uses 0.4 gigabytes

From the information, Morgan's phone can hold 4 gigabytes of music. He also already has three oldies playlists that take up 1.2 gigabytes each.

A rock playlist is 0.8 gigabytes. Therefore, the space remaining will be:

= Total gigabytes - Space used

= 4 gb - (1.2 × 3)

= 4gb - 3.6gb

= 0.4gb

b. The possible error that was made was that Jorge shifted the decimal backward.

A quotient is a quantity created by the division of two numbers in mathematics. The quotient is widely used in mathematics and is also known as the integer component of a division, a fraction, or a ratio. A decimal is a number with a whole and a fractional part. Decimal numbers are between integers and represent a numerical value for a whole plus some fraction of a whole.

From the information, it should be noted that Natasha and Jorge were asked to find the quotient to the decimal division problem 18.8÷1.6.

a. It should be noted that the division of the decimals will be:

A) Hence,  proven that 3y²– 24y – 47 = 0

B) After solving the simultaneous equations y1 = −1.627314 or −1.6 and y2 = 9.627314  or 9.6.

Equations that are simultaneously solved and have two or more common variables are known as simultaneous equations (that is, simultaneously). Since the unknown variables in both equations, x and y, are the same, they can be solved simultaneously to find the values of the variables.

As an illustration, equations x + y = 5 and x - y = 6 are examples of simultaneous equations. Simultaneous equations can be resolved in a variety of ways, including graphically, by substitution, and by elimination.

a) Given that

x - 6y = 10

Lets solve for x

x = 10 + 6y

And 3y² = 4x + 7

Lets solve for x

x = (3y² - 7)/4

As x is equal lets cross multiply and we get

10 + 6y = (3y² - 7)/4

40 + 24y =  3y² - 7

47 + 24y = 3y²

0 = 3y² - 24y - 47

3y²– 24y – 47 = 0

B) To solve the simultaneous equations

Lets convert them to standard format

x - 6y = 10 already in standard format

3y² = 4x + 7

4x - 3y² = -7 in standard format

Now solve

⇒                 x - 6y = 10      (x4)

                   4x - 3y² = -7    (x1)

⇒                  4x - 24y = 40

                -   4x - 3y² = -7

                     0 + 3y²– 24y = 47

⇒ 3y²– 24y = 47

⇒ Putting the value in quadratic formula

⇒ y1 = −1.627314 or −1.6

⇒ y2 = 9.627314  or 9.6

A) Hence,  proven that 3y²– 24y – 47 = 0

B) After solving the simultaneous equations y1 = −1.627314 or −1.6 and y2 = 9.627314  or 9.6.

Answer:

Step-by-step explanation:

1) Find the table

To find the numbers on the table, just substitute the number for x

If x = 0

y=-4x+3

y=-4(0) + 3

y= 0 + 3

y= 3

If x = 1

y=-4x+3

y=-4(1)+3

y= -4 + 3

y= -1

You can see a pattern, each x makes it go down by 4.

So the following will be...

if x = 2 -> -5

if x = 3 -> -9

2) Now fill in the table with the points

(0, 3) (Taken from the table, the x and y)

(1, -1)

(2, -5)

(3, -9)

3) Afterward draw a line through it. You will get your graph.

Explanation:

sigma = 120 = population standard deviation

n = 25 = sample size

sigma/sqrt(n) = standard deviation of the xbar distribution

sigma/sqrt(n) = 120/sqrt(25) = 24

The standard deviation of the sampling distribution of the mean for this sample is 24. Rephrased, the standard deviation of the xbar distribution is 24.

To get the variance, we square the standard deviation

variance = (standard deviation)^2

variance = 24^2

variance = 576

Keep in mind this is the variance of the xbar distribution, and not the original underlying distribution it came from.

Step-by-step explanation:

assuming you require the measure of the numbered angles.

∠ 5 and 148° are vertically opposite angles and are congruent , so

∠ 5 = 148°

∠ 6 and 148° are a linear pair and sum to 180° , that is

∠ 6 + 148° = 180° ( subtract 148° from both sides )

∠ 6 = 32°

∠ 6 and ∠ 7 are vertically opposite angles and are congruent , then

∠ 7 = 32°

∠ 3 and ∠ 6 are same- side interior angles and sum to 180° , that is

∠ 3 + 32° = 180° ( subtract 32° from both sides )

∠ 3 = 148°

∠ 1 and ∠ 3 are vertically opposite angles and are congruent , then

∠ 1 = 148°

∠ 1 and ∠ 2 are a linear pair and sum to 180° , so

∠ 2 + 148° = 180° ( subtract 148° from both sides )

∠ 2 = 32°

∠ 2 and ∠ 4 are vertically opposite angles and are congruent , then

∠ 4 = 32°

In summary

∠ 1 = 148° , ∠ 2 = 32° , ∠ 3 = 148° , ∠ 4 = 32° , ∠ 5 = 148° , ∠ 6 = 32° , ∠ 7 = 32°

There is strong positive association between the variables.

The strength of the linear link between two variables is assessed using correlation coefficients. A correlation coefficient with a value over zero denotes a positive link, whereas one with a value below zero denotes a negative relationship. A statistical indicator of how strongly two variables are linearly related is the correlation coefficient. From -1 to 1, its values are possible. A correlation coefficient of -1 indicates a perfect negative, or inverse, correlation, in which the values in one series rise as the values in the other fall, and the other way around. A value of 1 indicates a direct link that is 100 percent positive. There is no linear link when the correlation coefficient is zero.

The remainder when the polynomial f(x) is divided by the x - 5 is 0.

A polynomial is an equation made up of coefficients and indeterminates that uses only the addition, subtraction, multiplication, and powers of positive-integer variables.

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor in mathematics.

Consider the polynomial,

f(x) = x³ - x² - 17x - 15

The factor of the polynomial is x - 5.

So,

x - 5 = 0

x = 5

Substituting the value of x in the polynomial,

f(x) = x³ - x² - 17x - 15

f( 5 ) = 5³ - 5² - 17(5) - 15

f(5) = 125 - 25 - 85 - 15

f(5) = 125 - 125

f(5) = 0

Hence, the remainder is 0 when polynomial f(x) is divided by x - 5.

The cumulative frequency = 16

The relative frequency  = 32%

The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values.

To get relative frequency, we will take this cumulative number and divide by the total number of students. number of 21 or more / total number of students = 16 / 50 = 0.32 or 32%.

The cumulative frequency of students who earned a score of 21 or higher on the quiz is =16.

Total frequency is = 4+8+15+7+7+3+4+2=50.

So the relative cumulative frequency is
