Answer:

Total amount Omar earn = $120

Step-by-step explanation:

Given:

Total amount Omar, Hala and Lujain got paid = $240

Ratio of money Omar, Hala and Lujain got paid = 5:9:10

Find:

Total amount Omar earn

Computation:

Total amount Omar earn = [Total amount Omar, Hala and Lujain got paid][Omar'ratio / Total ratio]

Total amount Omar earn = [240][5 / (5+9+10)]

Total amount Omar earn = [240][5 / (24)]

Total amount Omar earn = [24][5]

Total amount Omar earn = $120

Answer:

a=4

Step-by-step explanation:

When a die is rolled, here it's Total possible outcome is= 6

and sample space is = 2 ( i.e. 1 & 2)

So. Probability of getting less than 3 = 26

=13

That's it

Answer:

Step-by-step explanation:

sin(110°) / AC  = sin(40°) / 12

now use algebra skillz to solve for AC

12*sin(110°) / sin(40°) = AC

17.5 =AC

Answer:

D. S’ is the result of switching coordinates of S.

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Type of transformation are translation, reflection, rotation and dilation.

If a point A(x, y) is reflected along the x axis, the new point is A'(x, -y). If a point A(x, y) is rotated 90°  counterclockwise about the origin, the new point is A'(-y, x).

Let us assume that S is at (x, y). Hence, if point S is reflected about the x-axis in the coordinate plane to get (x, -y). If it is then rotated 90°  counterclockwise about the origin, the new point is at  S'(y, x). S’ is the result of switching coordinates of S

Answer:

714m^2

Step-by-step explanation:

So, as we said in the comments, since they didn't give the radius, we have to assume the center is a square. That means the area of the center part is 20m x 20m, and the diameter of the circular ends is 20m as well.

Area of center: 20 x 20 = 400m^2

Area of ends:

Area = (pi)(r)^2

The radius = 1/2 the diameter = 10m

Area = (3.14)(10)(10)

Area = 3.14 x 100 = 314m^2

Now, if it only had one semicircle on the end like your previous question, we'd have to divide this answer by 2, but the circular area we just calculated covers both ends, so the total area = the square center + the circular area

400 + 314 = 714m^2

Answer:

D) $0.15/hr

Step-by-step explanation:

Divide 1.5 by 10 and you get 0.15, check your work by dividing 3 by 20=0.15, you divide the numbers in which are a line, for example look at the cost 3 and hours used 20, (if that makes sense)

Answer:

1/2

Step-by-step explanation:

The Rational Root Theorem says that any rational root has

1. a numerator that is a factor of the constant term

2. a denominator that is a factor of the leading coefficient (that's attached to the highest-power term)

Numerator:  [tex]\pm 1[/tex]

Denominator: [tex]\pm 2[/tex]

That means there are only two possible rational roots: [tex]\pm \frac{1}{2}[/tex]

Try them both by plugging them into the polynomial.

[tex]2\left(\frac{1}{2}\right)^3 + 3\left(\frac{1}{2}\right)^2 -1= \frac{1}{4}+\frac{3}{4}-1 =0[/tex]

Aha!  The negative one-half value does not produce 0

Answer:

0.2143 probability that all of them practice satirical.

Step-by-step explanation:

The comedians are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

8 comedians means that [tex]N = 8[/tex]

6 practice satirical means that [tex]k = 6[/tex]

Sample of 4 means that [tex]n = 4[/tex]

What is the probability that all of them practice satirical?

This is P(X = 4). So

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 4) = h(4,8,4,6) = \frac{C_{6,4}*C_{2,0}}{C_{8,4}} = 0.2143[/tex]

0.2143 probability that all of them practice satirical.

Answer:

36

Step-by-step explanation:

Work out the terms inside the parenthesis from x = 2 to x = 5. Hint: there will be 4 terms.

x = 2 ---> 0

x = 3 ---> 1

x = 4 ---> 2

x = 5 ---> 3

The sigma symbol means that you have to add them all up so the sum is 6. Therefore,

(6)^2 = 36

Answer:

36

Step-by-step explanation:

Sum the terms (x - 2) for x = 2 to 5 then square the result

[ (2 - 2) + (3 - 2) + (4 - 2) + (5 - 2) ]²

= ( 0 + 1 + 2 + 3 )²

= (6)²

= 36

Answer:

48

Step-by-step explanation:

the answer is 48 because according to the results 48% of people prefered given device and 48% of 100 is 48

78=.75x or $78 is 75% of the original price before the discount 78/.75=x x=104 is the original price proof 104-(.25*104)=78 104-26=78 78=78

Answer:

x = 18

Step-by-step explanation:

We can say that:

(2x + 13) + 90 + 41 = 180

2x + 144 = 180

2x = 36

x = 18
