Answer:

[C] 75/100

Step-by-step explanation:

Given:

What is 0.75 written as a fraction?

Solution:

0.75 = Decimal

Rewriting the decimal number as a fraction with 1 in the denominator

[tex]0.75=\frac{0.75}1[/tex]

Now, multiply to remove the 2 decimal places. So, you multiply top and bottom by 10²  = 100

10²  is the same thing as 100 because 10²  = 10 × 10 and 10 × 10 = 100

[tex]\frac{0.75}{1}\times\frac{100}{100}=\frac{75}{100}[/tex]

Thus, the answer is [C] 75/100

The value of t  at a height of 11 feet is 0.36 sec when the ball is going upwards and 1.39 seconds when the ball is coming downwards.

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

Given that the height of the ball at time t is given by the function,

[tex]h(t) = 3+ 28t -16t^2[/tex]

where t is in seconds and h is in feet.

Now, the height of the ball is given to be 11 feet, therefore, substituting the value of h in the function as 11,

[tex]h(t) = 3+ 28t -16t^2\\\\11 = 3+ 28t -16t^2\\\\-16t^2 + 28t +3 -11 = 0\\\\-16t^2 + 28t -8 = 0[/tex]

Now, solving the given quadratic equation, we will get,

[tex]x= \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\t = \dfrac{-(28)\pm \sqrt{(28)^2-4(-16)(-8)}}{2(-16)}\\\\t= 0.36\ or\ 1.39[/tex]

Hence, the value of t  at a height of 11 feet is 0.36 sec when the ball is going upwards and 1.39 seconds when the ball is coming downwards.

Answer:

diameter-- last picture on right side

radius-second last picture on right side

πd=2πr

2r=d/2

Step-by-step explanation:

diameter is a line segment that goes through the center of a circle

this will match to the last image on the right side

radius is half of the diameter or from a point on the outer edge of the circle to the center

this will match to the second one on the right side

πd-- d=2*radius

2πr

2r=d/2

because radius is half of the diameter

Answer:

y = -4/5x-34/5

Step-by-step explanation:

1. Put into slope-intercept form: 5x-4y = 10 ⇒ 4y = 5x-10 ⇒ y = 5/4x - 5/2

2. A perpendicular slope is the negative reciprocal of the original slope. ⇒ m = -4/5

3. Make a general solution using the new slope: y = -4/5x + b

4. Plug in the point (-1,-6) and solve for b: -6 = -4/5(-1) + b ⇒ -6-(4/5) = b ⇒    

b = -34/5

5. Put b in the general solution to find the particular solution: y = -4/5x-34/5

Answer:

To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate. So in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the unit rate.

Also, what are unit rates? A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

The question is an illustration of conditional probability, and the value of the conditional probability P(A|B) is 0.38

The question is incomplete, as the required parameters are not given.

So, I will give a general explanation.

The question is an illustration of conditional probability

The conditional probability is used to determine the probability of an event, given that another independent event has already occurred.

The conditional probability is calculated using:

P(A|B) = n(A and B)/n(B)

Assume the following parameters

n(A and B) = 9

n(B) = 24

The equation to calculate the probability expression is represented as:

P(A|B) = n(A and B)/n(B)

Substitute the assumed values

P(A|B) = 9/24

Evaluate the expression

P(A|B) = 0.38

Hence, the value of the conditional probability P(A|B) is 0.38

For the  Northside players, the median is 36, the range is 32 and the IQR is 18. For the southside Players :  the median is 26, the range is 12 and the IQR is 12.

The median is regarded as the middle number among a series of  sorted numbers  that are placed in ascending or descending order.

Note that from the image attached, the northside ages are 22, 25, 28, 29, 29, 36, 36, 41, 49, 49, 54.

The median northside ages therefore is 36

For Range = Highest number - Lowest number

54-22 = 32

IQR = Q₃ - Q₁

Note that first quartile Q1 is said to be the median of the n lowest values and third quartile Q3 is the median of the n highest values.

Lowest value is 22 + 25/2 = 28.5.

Highest value is 49 + 44/ 2=  46.5.

Therefore,  IQR = Q₃ - Q₁

46.5 - 28.5 =

IQR = 36

Note, for Southside Players;

If the Ages of Actors is the Southside Players are 20 22 24 26 28 30 32 34.

Then the median is =  26

Range is = 34-22 = 12

IQR = Q₃ - Q₁

Lowest = 20 + 22/ 2 = 21

Highest is 32 + 34 / 2 = 33

33 - 21

IQR  = 12

Therefore, for the  Northside players, the median is 36, the range is 32 and the IQR is 18. For the southside Players :  the median is 26, the range is 12 and the IQR is 12.

La diferencia entre los ángulos AOB y COD del sistema de tres ángulos consecutivos es igual a 25°.

La medida del ángulo BOC pertenenciente al sistema de tres ángulos consecutivos es igual a 20°.

Por la geometría Euclídea conocemos que un conjunto de ángulos cuando comparten entre cada par de ángulos vecinos comparten el mismo vértice y la misma semirrecta.

De acuerdo con el enunciado, tenemos las siguientes condiciones:

∠AOB + ∠BOC = 125°   (1)

∠BOC + ∠COD = 100°  (2)

Por (1) y (2) tenemos las siguiente identidad:

∠AOB - 25° = ∠COD

∠AOB - ∠COD = 25°

La diferencia entre los ángulos AOB y COD del sistema de tres ángulos consecutivos es igual a 25°. [tex]\blacksquare[/tex]

En el segundo caso, tenemos el siguiente sistema:
