Answer:

A) The graph represents the function h(x) = 1.5x + 3

D)The plant grows about 1.5 inches each week.

Step-by-step explanation:

The following statements are true -

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have Kay created a linear graph to track the height in inches [h] of a pepper plant over a number of weeks [x]. The plant's height was 3 inches when purchased.

Since the slope of the graph is 1.5 inches. We can write the equation of the graph as -

y = 1.5x + 3

This also shows, the plant grows about 1.5 inches each week.

Therefore, the following statements are true -

Positive because you have two negatives. (3)(-25) is a negative number, (7)(-24) is also a negative number. Negative * negative is positive.

First option is correct

Answer:

First one

Step-by-step explanation:

(3)(−25): product is negative (-75)

(7)(−24): product is negative (-168)

Multiply these values, which are negative, gives you a positive real number (12600) because two negatives gives you a positive

Answer:

The chance of getting a sample  proportion of 70% or greater is 0.026.

Step-by-step explanation:

We are given that a poll shows that 50% of students play sports .

A random sample of 20 students showed that  70% of them play sports.

Let [tex]\hat p[/tex] = sample proportion of students who play sports

The z-score probability distribution for the sample proportion is given by;

                           Z  =  [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex]  ~ N(0,1)

where, [tex]\hat p[/tex] = sample proportion of students who play sports = 70%

           p = population proportion of students who play sports = 50%

           n = sample of students = 20

Now, the chance of getting a sample  proportion of 70% or greater is given by = P([tex]\hat p[/tex] [tex]\geq[/tex] 70%)

   P([tex]\hat p[/tex] [tex]\geq[/tex] 70%) = P( [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] [tex]\geq[/tex] [tex]\frac{0.70-0.50}{\sqrt{\frac{0.70(1-0.70)}{20} } }[/tex] ) = P(Z [tex]\geq[/tex] 1.95) = 1 - P(Z < 1.95)

                                                                 = 1 - 0.97441 = 0.026

The above probability is calculated by looking at the value of x = 1.95 in the z-table which has an area of 0.97441.

Hence, the chance of getting a sample  proportion of 70% or greater is 0.026.

Answer:

A - -6x4y – 2x3y2 + 9x2y3 – 3xy4 + y5

I just took the test

The difference of the polynomials given is  -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵

Given are two polynomials are :

(-2x³y² + 4x²y3³ - 3xy⁴) and (6x⁴y - 5x²y³ - y⁵)

We need to subtract the polynomials and find the difference.

(-2x³y² + 4x²y3³ - 3xy⁴) - (6x⁴y - 5x²y³ - y⁵)

By multiplying the signs into the brackets

= -2x³y² + 4x²y3³ - 3xy⁴ - 6x⁴y + 5x²y³ + y⁵

Grouping the like terms, we get

= -2x³y² + (4x²y3³ + 5x²y³) - 3xy⁴ - 6x⁴y + y⁵

= -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵

Therefore, the difference between the polynomials is -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵

Answer:

The average rate of change of the function over the given interval is -6

Step-by-step explanation:

The function we want to find its average rate of change is;

F(x) = 17 - x^2

Mathematically, the average rate of change of a function F(x) over an interval (a,b) can be calculated as;

{F(b) - F(a)}/(b-a)

According to this question, a = 1 and b = 5

F(a) = F(1) = 17 -(1)^2 = 17 -1 = 16

F(b) = F(5) = 17 - 5^2 = 17-25 = -8

So making the substitution; we have

(-8)-16/(5-1) = -24/4 = -6

Answer:

A: -6

Answer:

For 130 non-fiction books, the number of fiction books can be from 270 to 278.

Step-by-step explanation:

Given that, there are 5 non-fiction books for every 9 fiction books.

Observe that, if the number of fiction books is less than 9, than there will be no no-fiction books.

So, there are 5 non-fiction books for every 9 to (9+8) fiction books

So, by elementary method, there will be 5n non-fiction books for every 9n+8 fiction books, where n is a natural number.

Or, if the number of non-fiction books is 5n, then the number of fiction books will be ranging from 9n to (9n+8).

For, 150 non-fiction books, 5n=150 or n=150/5=30.

Hence, the number of fiction books can be from 9n to (9n+8).

=9x30 to (9x30+8)

=270 to 278.

Hence, for 130 non-fiction books, the number of fiction books can be from 270 to 278.

Answer:

You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

Step-by-step explanation:

y=x-1 2x-3y=-1

y=6x-11 -2x-3y=7

y=-5x-17 -3x-3y=3

y=5x-7 -3x-2y=-12

To solve a system of  2  variables, only  2  equations are required. Choose the first two equations containing the variables in the system.

y = x − 1 2 x − 3 y = − 1

Subtract  x  from both sides of the equation.

y − x = − 1 2 x − 3 y = − 1

Reorder the polynomial.

− x + y = − 1 2 x − 3 y = − 1

Multiply each equation by the value that makes the coefficients of  x  opposite.

( 2 ) ⋅ ( − x + y ) = ( 2 ) ( − 1 ) 2 x − 3 y = − 1

Simplify.

− 2 x + 2 y = − 2 2 x − 3 y = − 1

Add the two equations together to eliminate  x  from the system.

− 2 x + 2 y = − 2 + 2 x − 3 y = − 1 − y = − 3

Multiply each term in  − y = − 3  by  − 1

y = 3

Substitute the value found for  y  into one of the original equations, then solve for  x .

x = 4

The solution to the independent system of equations can be represented as a point.

( 4 , 3 )

The result can be shown in multiple forms.

Point Form:

( 4 , 3 )

The median is 120, The lower quartile is 112 and The upper quartile is 140

and  interquartile range is 28.

The difference between the third and first quartiles is referred to as the interquartile range. Quartiles are the parceled values that partition the entire series into 4 equivalent parts. There are then three quartiles. The lower quartile is represented by Q1, the second quartile is represented by Q2, and the third quartile is represented by Q3, which is the upper quartile. As a result, the difference between the upper and lower quartiles constitutes the interquartile range.

Given data

115, 120, 118, 104, 109, 148, 135, 141, 139

arrange series in ascending order,

104, 109, 115, 118, 120, 135, 139, 141, 148

the middle term of series is 120

median = 120

for lower Quartile Q₁ = (109 + 115)/2 = 112

for upper Quartile Q₃ = (139 + 141)/2 = 140

interquartile range = Q₃ - Q₁  = 140 - 112 = 28

Hence the median = 120,  lower quartile = 112,  upper quartile = 140 and

interquartile range = 28.
