You flip a coin 50 times. Of the 50 flips, the coin landed on heads 30 times. Use the questions below to compare the experimental probability of flipping heads with the theoretical probability of flipping heads.

Answer:

y = 2x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = B(- 3, - 1 ) and (x₂, y₂ ) = A (1, 7)

m = [tex]\frac{7+1}{1+3}[/tex] = [tex]\frac{8}{4}[/tex] = 2 , then

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 7 ) , then

7 = 2 + c ⇒ c = 7 - 2 = 5

y = 2x + 5 ← equation of line

Answer:

3 people

Step-by-step explanation:

If 20 people each bring 3 food dishes to an awards banquet, the total amount of food brought will be (20 * 3) = 60foods

If the dishes are shared equally by 180 people at the banquet, then;

60foods = 180 people

1 food = x

Cross multiply

60* x = 180

60x = 180

x =180/60

x = 3

Hence 3 people will share 1 dish

Answer:

(-4,-5)

Step-by-step explanation:

[tex](c)\ 9 - (3 * 2) \div 3 + 6[/tex]

Step-by-step explanation:

Given

(a) to (d)

Required

Which equals 13

[tex](a):\ 9 + 3 * (2 \div 3) + 6[/tex]

Solve the bracket

[tex]9 + 3 * (2 \div 3) + 6 =9 + 3 * (\frac{2}{3}) + 6[/tex]

Open the bracket

[tex]9 + 3 * (2 \div 3) + 6 =9 +2 + 6[/tex]

[tex]9 + 3 * (2 \div 3) + 6 == 17[/tex]

[tex](b):\ (9 + 3) * 2 \div 3 + 6[/tex]

Solve the bracket

[tex](9 + 3) * 2 \div 3 + 6 =(12) * 2 \div 3 + 6[/tex]

Open bracket

[tex](9 + 3) * 2 \div 3 + 6 =24 \div 3 + 6[/tex]

Divide

[tex](9 + 3) * 2 \div 3 + 6 =8 + 6[/tex]

[tex](9 + 3) * 2 \div 3 + 6 =14[/tex]

[tex](c)\ 9 - (3 * 2) \div 3 + 6[/tex]

Solve the bracket

[tex]9 - (3 * 2) \div 3 + 6 =9 - (6) \div 3 + 6[/tex]

Remove bracket

[tex]9 - (3 * 2) \div 3 + 6 =9 - 6 \div 3 + 6[/tex]

Divide

[tex]9 - (3 * 2) \div 3 + 6 =9 - 2 + 6[/tex]

[tex]9 - (3 * 2) \div 3 + 6 =13[/tex]

[tex](d)\ (9 + 3 * 2) \div 3 + 6[/tex]

Solve the bracket (the product, first)

[tex](9 + 3 * 2) \div 3 + 6=(9 + 6) \div 3 + 6[/tex]

[tex](9 + 3 * 2) \div 3 + 6=15 \div 3 + 6[/tex]

Divide

[tex](9 + 3 * 2) \div 3 + 6=5 + 6[/tex]

[tex](9 + 3 * 2) \div 3 + 6=11[/tex]

Only (c) equals 13

Step-by-step explanation:

The pie chart is presented in 3D. While it may look interesting or cool, it's better to convey the data in a flat 2D form instead. The reason why is because it's possible to perceive some slices to be larger than they actually should be. The green slice shows the thickness of it, or the height of the pie slice. The same is for the yellow slice as well. We cannot see the thickness portions of the red or blue slices. So it's very possible that a reader may think that the yellow slice is larger than the blue one, even though they represent the same percentages (so the slices should be the same size).

Also, there's a worry that slices in the back further away from the camera will appear smaller due to the 3D nature of the graph. This helps make the yellow slice (which is closer to the camera) appear slightly larger than the blue slice (further away from the camera). These are slight differences that may be overlooked and could not be an issue; however, it is possible to distort things and make the differences greater. So that's one thing you have to be careful about when it comes to 3D graphs like this. The author of this graph may have not had an intention to deceive, and they may have simply wanted to make it look nice and catch the eye better, but there's no way of knowing for sure. It's simply best to always be on the lookout for anything misleading like this. It happens quite often in statistics.

Step-by-step explanation:

y = 400 × 0.75

y = 300

300 milligrams = 0.75 hours

x = 3 hours

3(300) = 0.75x

900 = 0.75x

x = 1200

Answer:

x = 15/8.

Step-by-step explanation:

Create an equation, let the number be x:

2/3 * x = 5/4

Now we multiply both sides by 3/2

3/2 * 2/3 x = 5/4 * 3/2

x = 15/8.

If the number of the years will be 7. Then the number of the retail stores will be 89.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A city manager made a scatter plot of the number of retail stores in a certain city over the years.

The scatter plot had a trend line with an equation of y = 11x + 12, where y is the total number of retail stores and x is the number of years since 1990 Mark and his family moved to the city in 1997.

Use the equation to predict the number of retail stores there were in 1997 will be

The number of the years will be

x = 1997 - 1990

x = 7 years

Then we have

y = 11 × 7 + 12

y = 77 + 12

y = 89

Answer: $150

Step-by-step explanation:

If Bilbo bought the ring for 70% of the original price, this means that he saved:

= 100% - 70%

= 30%

$45 is therefore 30% of the original price.

Assuming the original price is x:

30% * x = 45

x = 45/30%

x = $150

Answer:

€99

Step-by-step explanation:

The computation of the original price (before the rebate)  of this pair of shoes is shown below:

Given that

The cost of pair of shoes is € 69.30 i.e. after 30% discount

So, the original price would be

= € 69.30 × 100 ÷ 0.70

= €99

The € 69.30 shows the 70% value according to this we determine 100% value

Answer:

Option B

Step-by-step explanation:

By applying cosine rule in the given triangle ABC,

BC² = AC² + AB² - 2(AC)(AB)cos(∠A)

BC² = (26)² + (23)² - 2(26)(23)cos(47°)

BC² = 676 + 529 - 815.67

BC² = 389.33

BC = √(389.33)

BC = 19.73

Therefore, Option B will be the correct option.

Answer:

the desired equation is y = – 4x + 3

Step-by-step explanation:

Parallel lines have the same slope and thus similar equations.   Thus, the equation of a line parallel to the given line has the form y = – 4x  + C.  We need only find C.

The new line goes through (2, -5), and so we substitute 2 for x and -5 for y to obtain

-5 = – 4(2) + C.  Then -5 + 8 = C, or C = 3.

Then the desired equation is y = – 4x + 3
