Answer: c.) The probability of getting heads when flipping a coin

Step-by-step explanation:

a.) The probability of a florist selling roses on Valentine’s Day

This is a biased event because it has a too small range, ranging only to one day is not enough for a data set. This will be a overestimation which can't represent the whole.

b.) The probability of seeing a fireworks show on Independence Day

This is a biased event because it also has a small range, ranging only to one day is not enough for a data set. This will be a overestimation which can't represent the whole.

c.) The probability of getting heads when flipping a coin

This is not biased because there will be equal probability for getting heads or the opposite. The range is neutral as heads is half part of coin, and tails is the other part of coin.

d.) The probability of a college graduate earning more money than a high school graduate

This is a biased event, because it will be an obvious answer which having an obvious answer to one event will be biased.

Hope this helps!! :)

Answer:

75

Step-by-step explanation:

Let full marks be x

Then pass marks is 40% of x which is 0.4x

As per given, we have

22= 0.4x - 8

Solving for x

0.4x = 30

x = 30/0.4

x = 75

So full marks is 75

Answer:

2(4) + 3(4)³ ≠ 5(4)⁴

Step-by-step explanation:

To determine if the two expressions, 2y + 3y³ is the same as 5y⁴, we can set both expressions equal to each other. Then replace y with a value to find out, if what you have on the both sides are equal or not.

Thus: 2y + 3y³ = 5y⁴

Replace y with 4 in the equation

2(4) + 3(4)³ = 5(4)⁴

8 + 192 = 1,280

200 ≠ 1,280

What we have on one side of the equation is not equal to what we have in the other side. So therefore, both expressions are not equal. Hence, they are not the same.

The statement that shows 2y + 3y³ and 5y⁴ are not the same is:

2(4) + 3(4)³ ≠ 5(4)⁴

Answer:

a is the value of X

Step-by-step explanation:

The value of the variable x is 40. Then the correct option is C.

The circle is at equidistant of points drawn from the center. The radius of a circle is the distance between the center and the circumference.

Half the differential between the dimensions of the captured arcs is the measurement of an angle made by the two secants, two tangents, or a secant and a tangent from just a point are outside the circle.

Then the equation will be given as,

35° = [(4x + 50) – (3x + 20)] / 2

Simplify the above equation, then the equation will be

35 = (4x – 3x + 50 – 20) / 2

70 = x + 30

 x = 70 – 30

 x = 40

Then the value of the variable x is 40.

Then the correct option is C.

Answer:

Three decimals

Step-by-step explanation:

Two decimals coming from the first number and one coming from the second one: 4.393 is the product

Answer:

3 decimal places (the answer to the equation is 4.393)

Step-by-step explanation:

When multiplying decimals, multiply them as whole numbers, count the amount of decimal places and both, add the number of decimal places up, and that's how many decimal places are in your answer.  So the first one has two decimal places and the second one has one decimal places making your answer have three decimal places.

Answer:

[tex]1\frac{19}{30}[/tex]

Step-by-step explanation:

To operate between mixed numbers is always better to write then in fraction form first (as improper fractions), and then operate using the rules to combine fractions.

For the first mixed number :

[tex]4\frac{5}{6} = 4+\frac{5}{6} =\frac{24}{6} +\frac{5}{6}=\frac{29}{6}[/tex]

For the second mixed number:

[tex]3\frac{1}{5} =3+\frac{1}{5}=\frac{15}{5}+\frac{1}{5}=\frac{16}{5}[/tex]

So now we have to subtract these two fractions, so we need to write them with the same common denominator (6 x 5 = 30):

[tex]\frac{29}{6}-\frac{16}{5}=\frac{145}{30} -\frac{96}{30}=\frac{49}{30}[/tex]

and finally we write the obtained answer in mixed number form:

[tex]\frac{49}{30} =1+\frac{19}{30} =1\frac{19}{30}[/tex]

La media es el valor promedio de un conjunto de datos numéricos y es también llamada promedio o media aritmética.

Su cálculo se obtiene al sumar todos los datos disponibles y dividir el resultado por el número total de esos datos:

[tex]Promedio=\frac{x_{1} +x_{2} +x_{3}+...+x_{n} }{N}[/tex]

donde N el número total de observaciones.

En este caso:

Answer:

[tex]x = \frac{1}{4}[/tex]

Step-by-step explanation:

[tex]-50 = -5x - 3(5x + 15)[/tex]

Use -3 to open the bracket

[tex]-3(5x +15)\\\\= -15x -45\\\\ -50 = -5x-15x -45[/tex]

Collect like terms

[tex]-50 +45 =-5x -15x[/tex]

Simplify

[tex]-5 = -20x[/tex]

Divide both sides of the equation by -20

[tex]\frac{-5}{-20} = \frac{-20x}{-20} \\\\1/4 =x\\\\x = \frac{1}{4}[/tex]

Answer:

[tex]y=3x+3[/tex]

Step-by-step explanation:

Use the slope-intercept form:

[tex]y=mx+b[/tex]

m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( [tex]\frac{rise}{run}[/tex] ).

If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:

[tex]y=mx+3[/tex]

Now find the slope. Use the slope formula:

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

You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:

[tex](0_{x1},3_{y1})\\(1_{x2},6_{y2})\\\\\frac{6-3}{1-0}=\frac{3}{1}=3[/tex]

The slope is 3. Insert this value:

[tex]y=3x+3[/tex]

Answer:

a) 7/4 b) 5 c) 2

Step-by-step explanation:

Logrithmic Rule for a and b

Let a, M, N be positive real numbers.

a)  

logaM - logaN = loga(M/N)

log9(7) - log9(4) = log9 (7/4)

b)

logaM + logaN = logaMN

log2 (x) + log2(9) = log2(45)

x9=45

(x9)/9 = 45/9

x = 5

c)

Change of base formula.

logb​(x)=logd​(b)/logd​(x)​

x log6(5) = log6(25) divide each term by log6(5)

x log6(5) / log6(5) = log6(25) / log6(5)   Cancel common factor log6(5)

x = log6(25) / log6(5)

x = log6(5^2) / log6(5)

Expand log6(5^2) by moving 2 outside the logarithm.

x = 2log6(5) / log6(5) cancel the like term log6(5)

x = 2

Answer:

x = 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Subtract x from both sides.

−3x+25=16

Step 3: Subtract 25 from both sides.

−3x=−9

Step 4: Divide both sides by -3

x=3

Answer: -25

Step-by-step explanation:

-9 - 16 = -25  

-9-16   is the same as -9 + -16  which gives you  -25
