Answers

Answer:

Multiply both sides by [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2}{5}x = 10[/tex]

Required

Get an equivalent of [tex]x = 25[/tex]

To do this, we simply multiply through by [tex]\frac{5}{2}[/tex]

[tex]\frac{5}{2} * \frac{2}{5}x = 10 * \frac{5}{2}[/tex]

[tex]\frac{5*2}{2*5} x = 10 * \frac{5}{2}[/tex]

[tex]\frac{10}{10} x = 10 * \frac{5}{2}[/tex]

[tex]\frac{1}{1} x = 10 * \frac{5}{2}[/tex]

[tex]x = 10 * \frac{5}{2}[/tex]

[tex]x =\frac{10*5}{2}[/tex]

[tex]x =\frac{50}{2}[/tex]

[tex]x = 25[/tex]

Answer:

11h +129

Step-by-step explanation:

8h + 129 + 3h = ?h + ?

11h +129

Answer:11h +129

Step-by-step explanation:You add like terms together which are 8 h and 3h which gives you 11 h.And you have 129 left so you add 11 h to 129 .So you get 11 h +129 as your equivalent expression to represent Bradens total earnings for this week.

Find the first four terms of the sequence given by the following.
4,=(-1)".31%, n=1, 2, 3, ...

Answers

Answer:

The first term of the sequence is:

a₁ = -3a₂ = 12a₃ = -27a₄ = 48

Step-by-step explanation:

Given the sequence

aₙ = (-1)ⁿ · 3n²

substituting n = 1 to determine the first term

a₁ = (-1)¹ · 3(1)²

a₁ = (-1)¹ · 3(1)²

Applying the exponent rule: [tex]a^1=a[/tex]

a₁ = -1 · 3(1)

a₁ = -1 · 3

a₁ = -3

substituting n = 2 to determine the 2nd term

a₂ = (-1)² · 3(2)²

a₂ = 1 · 3(4)

a₂ = 12

substituting n = 3 to determine the 3rd term

a₃ = (-1)³ · 3(3)²

a₃ = -1 · 3(9)

a₃ = -1 · 27

a₃ = -27

substituting n = 4 to determine the 4th term

a₄ =  (-1)⁴ · 3(4)²

a₄ = 1 · 3(16)

a₄ = 1 · 48

a₄ = 48

Therefore, the first term of the sequence is:

a₁ = -3a₂ = 12a₃ = -27a₄ = 48

What is the slope of the line on the graph?



Enter your answer in the box.

Answers

Answer:

6

Step-by-step explanation:

The find the slope of a line given any two points, we can use the slope formula given by:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We can choose the two points (0, -1) and (1, 5) from the graph.

Let (0, -1) be (x₁, y₁) and let (1, 5) be (x₂, y₂). So:

[tex]\displaystyle m=\frac{(5)-(-1)}{(1)-0}=\frac{6}{1}=6[/tex]

Hence, the slope of the line is 6.

slope is the ratio of vertical increase to horizontal increase

The accompanying data on x= head circumference z score (a comparison score with peers of the same age - a positive score suggests a larger size than for peers) at age of 6 to 14 months and y =volume of cerebral grey matter (in ml) at age 2 to 5 years were read from a graph in an article.
A) what is the value of the correlation coefficient? (Give the answer to two decimal places.) r=
B)Find the equation of the least- squares lines. (Give the answer to two decimal places.)
C) Predict the volume of cerebral grey matter for a child whose head circumference z score at age 12 months was 1.9. (Give the answer to two decimal places.)

Answers

Answer:

[tex]r=0.77[/tex], [tex]\hat{y}=770.50+39.37x[/tex] and volume of cerebral brey matter for a child whose head circumference Z score at age 12 months was 1.9 is  [tex]\hat {y}=920.10[/tex]

Step-by-step explanation:

We attached a table below,

[tex](a)[/tex]  We attached a table below,

Therefore ,

correlation coefficient  [tex]r=\frac{\frac{1}{18}(21766.7)-(\frac{27.25}{18} )(\frac{13890}{18} ) }{\sqrt{\frac{1}{18} (59.8435)-(\frac{27.25}{18} )^2}\sqrt{\frac{1}{18}(10767400)-(\frac{13890}{18} )^2 } }[/tex]

                                         [tex]=\frac{41.04}{53.19}[/tex]

                                         [tex]=0.77[/tex]

[tex](b)[/tex]    We calculate the least squares equation.

      [tex]b_1=r(\frac{\sigma_y}{\sigma_x} )\\ =(0.77)(\frac{\sqrt{\frac{1}{18} (10767400)-(\frac{13890}{18} )^2} }{\sqrt{\frac{1}{18}(59.8435)-(\frac{27.25}{18} )^2 } } )\\ =0.77(\frac{52.15}{1.02} )\\ =0.77(51.13)\\ =39.37[/tex]

Now , calculate intercept coefficient.

[tex]b_0=\bar{y}-r\bar{x}\\[/tex]

    [tex]=(\frac{\sum{y}}{n} )-0.77(\frac{\sum{x}}{n} )\\=(\frac{13890}{18} )-0.77(\frac{27.25}{18} )\\=771.67-1.17\\=770.50[/tex]

Therefore, the regression equation is, [tex]\hat{y}=770.50+39.37x[/tex]

[tex](c)[/tex]    Find the volume of cerebral brey matter for a child whose head circumference Z score at age 12 months was 1.8

[tex]\hat{y}=770.50+39.37x[/tex]

   [tex]=770.50+39.37(1.9)\\=770.50+74.80\\=920.10[/tex]

Answers

Answer:

[tex]6g -86h[/tex]

Step-by-step explanation:

[tex]10( 7g-9h) -4h - 8(-h + 8g)[/tex]

1) First, distribute the 10 and the -8 to the terms in the parentheses next to them. Remember, don't distribute to the -4h since it is not in the parentheses.  

[tex]10( 7g - 9h) -4h - 8(-h + 8g)\\70g - 90h-4h+8h-64g\\[/tex]

2) Next, combine like terms. (Any terms that have the same variables must be added together by their coefficients.)

[tex]70g - 90h-4h+8h-64g\\\\70g-64g-90h-4h+8h\\6g-86h[/tex]

There are no more like terms to combine, so [tex]6g -86h[/tex] is the answer.

Answers

Answer:Mwamini drinks juice at a rate of 40 seconds per liter, and her time limit is 120 seconds.

Answer:Yes

Step-by-step explanation:

1) Mwamini drinks juice at a rate of 40 seconds per liter, and her time limit is 120 seconds.

2) Mwamini can drink 2 liters of water and 1 liter of juice  within her time limit.

What is inequality?

"It is a mathematical statement of an order relationship (greater than, greater than or equal to, less than, or less than or equal to) between two algebraic expressions."

For given question,

We have been given an inequality 25W + 40J < 120

W represent the number of liters of water and J represent the number of liters of juice.

Mwamini drinks water at a rate of 25 seconds per liter.

Mwamini drinks juice at a rate of 40 seconds per liter, and her time limit is 120 seconds.

If Mwamini drinks 2 liters of water and 1 liter of juice.

Here, W = 2 lit and J = 1 lit

So, ⇒ 25W + 40J

     = 25(2) + 40(1)

     = 50 + 40

     = 90

      < 120

This means, Mwamini can drink 2 liters of water and 1 liter of juice  within her time limit.

the midpoint of the line segment from p 1 p 2 is (- 6, 2) . if p 1 =(-8,2) , what is p 2 ?

Answers

If we have 2 coordinates (x1,y1) and (x2,y2), the midpoint is given by the following equation:

((x1+x2)/2,(y1+y2)/2)

We have the first set of coordinates which is (-8,2) and we have the midpoint which is (-6,2)..

For the x-coordinate:

(-8+x2)/2=-6

-8+x2=-12
x2=-12+8
x2=-4

For the y-coordinate:

(2+y2)/2=2
2+y2=4
y2=2

So the coordinate p2 will be (-4,2)
