Answer:

For every 5 students scoring in the 60s, there were 2 students scoring in the 70s.

Step-by-step explanation:

There are 40 scorers in the 60s and 16 scorers in the 70s. These are ratios, so the ratio between the 60s and the 70s would be 40/16. This fraction can be simplified down to 5/2. This means that for every 5 students scoring in the 60s, 2 scored in the 70s.

Answer:

(2,0) or 2

Step-by-step explanation:

The x-intercept is the point where the line intercepts or goes through the x-axis. The x-axis is the horizontal line that is labeled x.

Another way to find the x-intercept is to find the x value when the y value or f(x) equals zero.

Answer:1367

Step-by-step explanation:Lets assume the amount spent on everything else be "x".

We know total cost can not exceed $2000.

∴ Forming an inequation to find the amount spent on everything else.

⇒  

⇒  

Now, solving it to find x

Subtracting both side by 637

⇒

∴  

Hence, he can spend maximum of $1367 for eveything else.

Solution :

From the output of regression equation given by

Number of death of children in 1991 = [tex]$-5.21226+1.003538 \times \text{ No. of child death in 1985}$[/tex]

Now, number of death of children in the year 1991 = [tex]$-5.21226+1.003538 \times \text{ No. of child death in 1985}$[/tex]

For x = no. of deaths of children in the year 1985 = 65

So substituting in the regression equation,

No. of deaths of children in year 1991 =  [tex]$-5.21226+1.003538 \times 65$[/tex]

                                                              = [tex]$60.01771$[/tex]

                                                              ≈ 60

Now residual = [tex]$\text{observed y - predicted y}$[/tex]

                      = [tex]$42-60$[/tex]

                      [tex]$-18$[/tex]

Part(a): Number of child deaths is,

[tex]1991=-5.21226+1.003538\times[/tex]  number of child deaths in 1985

Part(b):

The number of child deaths in 1991 is 60.

Part(c): The observed is -18.

Part(a):

The given data can be solved by excel as,

From the output regression equation is,

Number of child deaths is,

[tex]1991=-5.21226+1.003538\times[/tex]  number of child deaths in 1985

Part(b):

Number of child deaths is,

[tex]1991=-5.21226+1.003538\times[/tex]  number of child deaths in 1985

For x=Number of child deaths in 1985=65

Number of child deaths in 1991 is,

[tex]-5.21226+1.003538\times65=60.01771\\=60[/tex]

Part(c):

Residual=observed y-predicted y

=42-60

=-18

Question:

Linear Equation In One Variable

solve x,

[tex]\frac{3x}{2} -7 = 5[/tex]

Answer:

[tex]x = 8[/tex]

Step-by-step explanation:

Given

[tex]\frac{3x}{2} -7 = 5[/tex]

Required

Solve for x

[tex]\frac{3x}{2} -7 = 5[/tex]

Multiply through by 2

[tex]2(\frac{3x}{2} -7) = 5 * 2[/tex]

[tex]2*\frac{3x}{2} -2 * 7 = 5 * 2[/tex]

[tex]3x - 14 = 10[/tex]

[tex]3x = 14 + 10[/tex]

[tex]3x = 24[/tex]

Solve for x

[tex]x = \frac{24}{3}[/tex]

[tex]x = 8[/tex]

Answer:

a) What is the amount off the original price?

= $8.4

b) What is the new price for the pair of shoes?

= $33.6

Step-by-step explanation:

a) What is the amount off the original price?

We are told that:

The sale price is 20% off the original price.

Original price = $42

Hence:

$42 × 20%

$42 × 20/100

= $8.4

b) What is the new price for the pair of shoes?

The new price =

0riginal price - Amount off the original price

= $42 - $8.4

= $33.6

The original price = $33.6

Answer:

48

Step-by-step explanation:

Given is an isosceles triangle:

[tex] \angle Y \cong \angle Z (isosceles \: \triangle \: theorem) \\

m\angle Z = m\angle Y=x\\

\therefore 84\degree + x\degree +x\degree = 180\degree \\

\therefore 84\degree + 2x\degree = 180\degree \\

\therefore 2x\degree = 180\degree - 84\degree \\

\therefore 2x\degree = 96\degree \\\\

\therefore x\degree = \frac{96\degree}{2} \\\\

\therefore x\degree = 48\degree \\

\therefore x = 48 \\

18 tests

Step-by-step explanation:

Create a proportion where x is the number of tests after 9 weeks:

[tex]\frac{10}{5}[/tex] = [tex]\frac{x}{9}[/tex]

Cross multiply and solve for x:

5x = 90

x = 18

So, after 9 weeks, Vera will have taken 18 tests

Answer:

18

Step-by-step explanation:

18

10 tests     =   x tests

/ 5 weeks =   / 9 weeks

10* 9= x5

Step-by-step explanation:

Answer:

0.84 or 16

Step-by-step explanation:

The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

Let the unknown number be "x"

If the resulting expression is 18, this will be expressed as 4x² - 7 = 18

Solving the resulting expression

[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]

Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2
