Please help ASAP!!! And explain how you did it too :,)

Answer:

it is option D standard form

Solution :

It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :

1. [tex]$P(x) \geq 0$[/tex]

2. [tex]$\sum_z P(x) = 1$[/tex]

Now consider,

[tex]$\sum_z P(x) = 1$[/tex]

⇒ [tex]$P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)+P(x=5)=1$[/tex]

⇒ [tex]$0.61+T+0.14+0.01+0.01+0.03=1$[/tex]

⇒ [tex]$0.8+T=1$[/tex]

⇒ [tex]$T=1-0.8$[/tex]

       = 0.2

Therefore, the value of T is 0.2

Thus, option (c) is correct.

Step-by-step explanation:

En álgebra, una ecuación cuadrática es cualquier ecuación que se puede reorganizar en forma estándar como ax ^ {2} + bx + c = 0 donde x representa una incógnita, y a, byc representan números conocidos, donde a ≠ 0. Si a = 0, entonces la ecuación es lineal, no cuadrática, ya que no hay término ax ^ 2.

Answer:

A=2(wl+hl+hw)

Step-by-step explanation:

Answer:

B. Decreasing; The slope of the line between points D and E is negative

Step-by-step explanation:

The graph clearly shows that the speed is decreasing between these points. This narrows down your options to either Option B or Option D. A completely vertical line has a slope of undefined. The line is not completely vertical and undefined, so Option D is incorrect. This leaves B as correct. A negative slope is a line rising right to left.

z = 36

Step-by-step explanation:

124 + 2z + 16 = 180

-16          -16

108 + 2z = 180

-108          -108

2z = 72

Answer:

A.) 96 ft/sec

Step-by-step explanation:

to find the average speed of the watermelon's fall in 6 seconds, substitute 6 as t in the equation and then divide by 6: [tex]y = \frac{16(6)^{2} }{6} = 96 ft/sec[/tex]

Answer:

Amount = $3.84

Step-by-step explanation:

Given the following data;

Total bill = $48

Tip = 8%

To find the amount of dollars tipped?

[tex] Amount = \frac {8}{100} * 48[/tex]

[tex] Amount = \frac {384}{100} [/tex]

Amount = $3.84

Therefore, the amount of dollars Mr. Cosgrove tipped is $3.84.

Answer:

x=12

Step-by-step explanation:

Let's solve your equation step-by-step.

34(16x+16)=37((438)(x)−21)

Step 1: Simplify both sides of the equation.

18x+12=158x−9

Step 2: Subtract 15/8x from both sides.

18x+12−158x=158x−9−158x

−74x+12=−9

Step 3: Subtract 12 from both sides.

−74x+12−12=−9−12

−74x=−21

Step 4: Multiply both sides by 4/(-7).

(4−7)*(−74x)=(4−7)*(−21)

x=12

Answer:

x=12

Answer:

x = 12

Step-by-step explanation:

34(16x + 16) = 37((438)(x) − 21)

18x + 12 = 158x − 9

18x + 12 − 158x = 158x − 9 − 158x

−74x + 12 = −9

−74x + 12 −12 = −9 −12

−74x = −21

(4−7) × (−74x) = (4−7) × (−21)

x = 12

Complete question :

A grocer sells mangos for $4 per pound and apples for $3 per pound. The grocer starts with

45 pounds of mangos and 50 pounds of apples each day. The grocer's goal is to make atleast $300 each day. What combinations of mangos and apples that could be sold to meet the goal. List two possible

combinations

Answer:

m = 45 ;a = 40

m = 45 ; a = 45

Step-by-step explanation:

Mangoes, m = $4

Apples, a = $3

Total :

45 pounds of mangoes

50 pounds of apple

4m + 3a ≥ 300

If m = 45

a = 40

4(45) + 3(40)

180 + 120 = 300

If m = 45 ; a = 45

4(45) + 3(45)

180 + 135 = 315

Hence, 2 possible combination :

m = 45 ;a = 40

m = 45 ; a = 45

For all possible solutions :

4m + 3a ≥ 300

Answer:

1.) R = 9 in

2.) R = 14.5 m

3.) D = 42 ft

4.) 26 mm

5.) 131.88 m

6.) 34.54 in

7.) 25.12 yd

8.) 28.26 mm

9.) 43.96 in

10.) 197.82 cm

11.) 263.76 cm

12.) 94.2 cm

13.) 97.34 m

14.) 138.16 cm

15.) 47.1 yd

16.) 285.74 cm

2(pi)r... literally plugged in

Answer:

4.5

Step-by-step explanation:

Probably too late for your RSM homework, but here is the solution:

6/(9-x) [Time they motored upstream] +6/x [Time it took the bottle to get back to the starting point] = 8/3 [Total Time]

Simplify to 54/(x(9-x))=8/3

Cross multiply: 162=(8x)(9-x)

Simplify -x^2+9x=20.25

Multiply both sides by negative one and move 20.25 to the other side. x^2-9x+20.25=0

Solve and get 4.5 :D!
