Answer:

  y = 3x - 2

Step-by-step explanation:

The slope-intercept form of the equation for a line is ...

  y = mx +b . . . . . slope m, y-intercept b

You are told the slope is m=3, and the y-intercept is b=-2. Put these values in the form and you have ...

  y = 3x -2 . . . matches the 2nd choice

Answer:  x = 3130/3 = 1043.333

Step-by-step explanation:   Solve  :    -3x+3130 = 0  

Subtract  3130  from both sides of the equation :  

                     -3x = -3130

Multiply both sides of the equation by (-1) :  3x = 3130

Divide both sides of the equation by 3:

                    x = 3130/3 = 1043.333

Answer: The scale used by Sarah is 1 to 43.2 inches ( drawing to actual)

Step-by-step explanation:

Here, we want to know the scale used for the drawing of the Dinosaur by sarah.

The actual height of the Dinosaur is 9 feet, but in her drawing she represented the height by 2.5 inches( 2 1/2 is same as 2.5 inches)

Mathematically, we know that 1 foot is 12 inches;

So the actual height of the Dinosaur is 9 * 12 = 108 inches

So practically, what she has done is to represent a height of 108 inches by 2.5 inches

So the scale factor used will be;

108/2.5 = 43.2

The scale used is 1 to 43.2 or simply 1:43.2 to represent the drawing to the actual

Answer:

£32.60

Step-by-step explanation:

Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1. Apple juice costs 56p for a 1-litre carton. Mango juice costs £1.20 for a 1-litre carton.

A pack of 80 plastic cups costs £1. Nita sells her fruit drink at a school concert in 250ml cups for 60p each.

We are told that Nita sells all her 80 cups

100 pence = £1

60p =

= 60/100

= £0.6

Hence, the selling price =

£0.6× 80

= £ 48

Profit = Selling Price - Cost Price

We have to find the Cost Price

A pack of 80 plastic cups costs £1.

Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1.

3 + 1 = 4

1 liter = 1000ml

For Apple Juice

3/4 × 1000ml = 750ml

For Mango Juice

= 1/4 × 1000ml = 250ml

This means she uses a mixture of 750 ml of Apple juice and 250 ml of Mango juice

Apple juice costs 56p for a 1-litre carton.

£0.56 = 1 liter = 1000ml

1000ml = £0.56

750 ml =

= 750 × 0.56/1000

= £0.42

Mango juice costs £1.20 for a 1-litre carton.

1000ml = £1.20

250 ml = x

x = 250 × 1.20/1000

= £0.3

Hence, the total cost for 1000ml of mixed juice = £0.3 + £0.42

= £ 0.72

We are told the content of each cup = 250 ml

For 80 cups she would need

80 × 250 ml

= 20000ml of the mixed juice

If 1000 ml = £0.72

20000ml = x

x = 20000 × £ 0.72/1000

x = £14.4

1 pack of 80 cups cost £1

Hence: £14.4 + £1

Cost Price = £15.4

Profit = Selling Price - Cost Price

Profit = £48 - $15.4

Profit = £32.60

Therefore, the money she gives to the school fund is £32.60

Step-by-step explanation:

Answer:

Question 1: 78 = angle 2.

Question 2: 7 = angle 2.

Step-by-step explanation:

Complementary deals with the angles adding up to 90 degrees.

So, do 90 - 12, which equals 78.

78 = angle 2.

90 - 83 = 7.

7 = angle 2.

Answer:

H0: ρ= 0 against Ha : ρ≠0

Step-by-step explanation:

The null hypothesis would be the weight gains of a sample of lambs on regular feed is equal to the weight gains of the sample that receives an additional niacin supplement against the claim that the weight gains are not equal .

H0: ρ= 0 against Ha : ρ≠0

Type 1 Error would be when the H0 is true and there's no difference but H0is rejected or Ha is accepted that there is difference in the weight gains.

Type 2 Error would be when the Ha is true and there is difference but Ha is rejected or H0 is accepted that there's no difference in the weight gains.

The appropriate conclusion would be Ha is accepted and H0 is rejected fail to reject.

A confounding variable is the one which effects the results . It is the biased variable which should be identified and ignored.

For example in this experiment the independent variable would be the amount of the supplement the dependent would the weight gain but the gender of the sheep is the confounding variable. It is not directly related to amount of supplement .

1) gender of sheep

2) the breed of sheep

3) the number of sheep

4) the height of sheep

Step-by-step explanation:

Here is the complete question.

A wire is first bent into the shape of a triangle. Each side of the triangle is 24in long. Then the wire is unbent and reshaped into a square. What is the length of a side of the square?

A triangle have 3 sides. If each sides is 24in long, the perimeter of the triangle will be:

P = s1 + s2 + s3

P = 24in + 24in + 24in

P = 72in

If the same length of wire is unbent and reshape into a square, this means:

Perimeter of the triangle = Perimeter of the square

Perimeter of the square = 72in

To get the length of a side of a square, we will use the formula:

Perimeter of a square = 4L

72 = 4L

L = 72/4

L = 18in

Hence the length of a side of the square will be 18in.

Answer:

4.12 PM

Step-by-step explanation:

Radio station 1 : Plays the song every 18 minutes

Radio station 2 : plays the song every 24 minutes

Both stations play the song at 3:00 PM.

When is the next time the stations will play the song at the same time?

Find the lowest common multiple of 18 and 24

18 : 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270

24 : 48, 72, 96, 120, 144, 168, 192, 216

The lowest common multiple of 18 minutes and 24 minutes is 72 minutes

72 minutes = 1 hour 12 minutes

Add 1 hour 12 minutes to 3:00 PM to know when both radio station will play the song at the same time

= 3.00 PM + 1 hour 12 minutes

= 4.12 PM

Answer:

The value of x is 5

Step-by-step explanation:

Let us simplify each side at first

∵ 2(x - 3) = 4(x - 4)

∴ 2(x) - 2(3) = 4(x) - 4(4)

∴ 2x - 6 = 4x - 16

→ Subtract 4x from both sides

∴ 2x - 4x - 6 = 4x - 4x - 16

∴ -2x - 6 = -16

→ Add 6 to both sides

∴ -2x - 6 + 6 = -16 + 6

∴ -2x = -10

→ Divide both sides by -2

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

∴ x = 5

∴ The value of x is 5

Answer: $298.97

Step-by-step explanation:

Cost of electronic games = $32.99

Cost of I- pad = $200

Since Ethan decided to purchase 3 electronic games and the l-pad, his total cost will be:

= (3 × $32.99) + $200

= $98.97 + $200

= $298.97

Answer:

y= 1/5x + -8

Step-by-step explanation: slope-intercept form= y=mx+b

y= the number on the y-axis or the simple y

m=slope

x= the number on the x-axis or the simple x

b= y-intercept

The required slope-intercept form of the equation is given as y = 1/5x - 8.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope intercept of the equation is given as,
y = mx + c,

From the given, we have a slope of line m = 1/5 and y-intercept, c = -8.
Now,
y = mx + c
y = 1/5x - 8

Thus, the required slope-intercept form of the equation is given as y = 1/5x - 8.
