Answer:

180

Step-by-step explanation:

From the table :

Slope :

m = (y2 - y1) / (x2 - x1)

m = (100 - 80) / (5 - 4)

m = 20 / 1

m = 20

y = 20x

Hence, when, x = 12

y = 20 * 12

y = 240

From the graph:

Slope :

m = (y2 - y1) / (x2 - x1)

m = (280 - 70) / (8 - 2)

m = 210 / 6

m = 35

y = 35x

When x = 12

Graph :

y = 35 * 12

y = 420

Difference :

420 - 240

= 180

Answer:

1:2 all you have to do is simplify

r = - 0.98754

Answer:

Slope = - 0.7120

SE = 1.295

Step-by-step explanation:

Given the data:

0 | 33.3

0 | 31.0

3 | 29.8

3 | 27.8

6 | 28.0

6 | 29.0

10 | 25.5

10 | 23.8

20 | 18.3

20 | 15.5

30 | 11.7

Using the relation to Obtian the slope :

Slope, b = r(Sy/Sx)

r = correlation Coefficient ; Sy = standard deviation of Y - values ; Sx = standard deviation of X-values

r = - 0.98754

Slope, b = - 0.98754(7.8471 / 10.884) = - 0.7120

SE = √SSresidual / df

df = n - 2 = 12 - 2 = 10

SSresidual = 16.7812

SE = √(16.7812/ 10)

SE = 1.295

Answer:

The total number of flowers grown is 163.

Step-by-step explanation:

Since in a flower fertilization experiment, the number of pink flowers grown is twice that of red flowers, and the number of white flowers grown is 3 more than that of red flowers, the number of white flowers grown is 37 fewer than that of pink flowers, to find the total number of flowers grown the following calculation must be performed:

P = 2R

W = R + 3

W = P - 37

W = W

R + 3 = 2R - 37

R + 3 + 37 = 2R

40 = 2R - R

40 = R

P = 2 x 40 = 80

R = 40

W = 40 + 3 = 43

80 + 40 + 43 = X

163 = X

Therefore, the total number of flowers grown is 163.

Answer:

3

Step-by-step explanation

Your problem statement tells you  

f(x) passes through point (3, negative 1)

g(x) passes through point (3, negative 1)

This tells you the input value that produces the same output value for the two functions is 3, and that output value is -1.

Answer:

4.123 km

Step-by-step explanation:

a squared = c sqaured - b squared

a squared = 9 sqaured - 8 squared

a squared = 81 - 64

a squared = 17

a = root 17

a = 4.123 km

Answer:

The average salary  of the Diamondbacks players  does not differ from that of all players in the National League.

Step-by-step explanation:

1) Formulate null and alternate hypothesis

H0: u1= u2 Ha: u1 ≠ u2

The null hypothesis is that the average salary of the Diamondbacks players does not differ from that of all players in the National League

against the claim

that the average salary of the Diamondbacks players differ from that of all players in the National League

The data given is

x1`= $2,308,488,  s1=  $3,427,508   and  n1 = 27

x2`=  $2,585,804,      s2=$3,500,708   and n2 = 27

2) The test statistic is

z= x1-x2/ sqrt( σ1 ²/n1 + σ2²/n2)

Putting the values

z = $2,308,488- $2,585,804/ sqrt( 3,427,508²/27 + 3,500,708²/27)

z= -0.294

3) The significance level is 0.05

The critical region is Z  =±1.96

4) Since the calculated value of z=  -0.294 is less than the z ∝=±1.96 we  do not reject H0.

5) the P-value can be calculated using the calculator.

The p-value is p = 0.7687

The average salary  of the Diamondbacks players  does not differ from that of all players in the National League.

Is this a true or false?

Answer:

11/8 and 21/16

Step-by-step explanation:

3 x 1 = 3

4 x 2= 8

3/8+3/4(convert to eighth's)

3/8+6/8=11/8

1 1/8 = 9/8

9 x 1 = 9

8 x 2 = 16

9/16+3/4(convert to sixteenth's)

9/16+12/16

21/16

Answer:

G. 25%

Step-by-step explanation:

given : The price of a video game was reduced from $60 to $45 .

$60 - $45 = $15

then, the percentage was the price of the video game reduced :-

reduction in price/previous price x 100 = 15/60 x 100 = 25%

the percentage was the price of the video game reduced = 25%

Answer: Section formula

Step-by-step explanation:

Given

The line segment AB with endpoints [tex]A(2,2)[/tex] and [tex]B(14,14)[/tex] is divided by a point X in the ratio 1:2

To verify that X divides the line segment in the ratio 1:2, we will use section formula. Section formula tells the coordinates of the point which divide the line segment in the certain ratio or vice-versa.

We will assume that X divides AB in k:1 and insert the values in the section formula. If the ratio k:1 comes out to be 1:2, then it verifies the claim.

Answer:

(1)

[tex]a = \frac{3\sqrt 3}{2}[/tex]

[tex]b = \frac{3}{2}[/tex]

(2)

[tex]a = \sqrt 6[/tex]

[tex]b = \sqrt 2[/tex]

Step-by-step explanation:

Solving (1):

Considering

[tex]\theta = 60^o[/tex]

We have:

[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

This gives:

[tex]\sin(60^o) = \frac{a}{3}[/tex]

Solve for a

[tex]a = 3 * \sin(60^o)[/tex]

[tex]\sin(60^o) = \frac{\sqrt 3}{2}[/tex]

So:

[tex]a = 3 * \frac{\sqrt 3}{2}[/tex]

[tex]a = \frac{3\sqrt 3}{2}[/tex]

To solve for b, we make use of Pythagoras theorem

[tex]3^2 = a^2 + b^2[/tex]

This gives

[tex]3^2 = (\frac{3\sqrt 3}{2})^2 + b^2[/tex]

[tex]9 = \frac{9*3}{4} + b^2[/tex]

[tex]9 = \frac{27}{4} + b^2[/tex]

Collect like terms

[tex]b^2 = 9 - \frac{27}{4}[/tex]

Take LCM and solve

[tex]b^2 = \frac{36 - 27}{4}[/tex]

[tex]b^2 = \frac{9}{4}[/tex]

Take square roots

[tex]b = \frac{3}{2}[/tex]

Solving (2):

Considering

[tex]\theta = 60^o[/tex]

We have:

[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

This gives:

[tex]\sin(60^o) = \frac{a}{2\sqrt 2}[/tex]

Solve for a

[tex]a = 2\sqrt 2 * \sin(60^o)[/tex]

[tex]\sin(60^o) = \frac{\sqrt 3}{2}[/tex]

So:

[tex]a = 2\sqrt 2 * \frac{\sqrt 3}{2}[/tex]

[tex]a = \sqrt 2 * \sqrt 3[/tex]

[tex]a = \sqrt 6[/tex]

To solve for b, we make use of Pythagoras theorem

[tex](2\sqrt 2)^2 = a^2 + b^2[/tex]

This gives

[tex](2\sqrt 2)^2 = (\sqrt 6)^2 + b^2[/tex]

[tex]8 = 6 + b^2[/tex]

Collect like terms

[tex]b^2 = 8 - 6[/tex]

[tex]b^2 = 2[/tex]

Take square roots

[tex]b = \sqrt 2[/tex]
