Theortical probability

A = 1/4

B = 1/3

C = 5/12

Experamental probability

A = 18/60 = 3/10

B = 20/60 = 1/3

C =  22/60 = 11/30

Answer:

Step-by-step explanation:

divide £36 in the ratio 5:1

36 : (5 + 1) =

36 : 6 =

6 (unit)

6 * 5 = 30

6 * 1 = 6

30 : 6

Step-by-step explanation:

the slope-intercept form is

y = ax + b

"a" is the slope (the slope is in all forms the factor of x). and "b" is the y-intercept (the y value when x = 0).

so the first equation is

y = -5x + b

b we get by using the point coordinates :

-22 = -5×5 + b = -25 + b

b = 3

so, the full equation is

y = -5x + 3

for the second equation we need to calculate the slope first. remember, it is the ratio "y coordinate change / x coordinate change" :

x changes by +1 (from -4 to -3).

y changes by +7 (from -2 to 5).

the slope is +7/+1 = 7/1 = 7.

the equation looks like

y = 7x + b

again, we use the coordinates of a point to get b. I picked (-4, -2) :

-2 = 7×-4 + b = -28 + b

b = 26

and the full equation is

y = 7x + 26

Answer:

x=120

y=180

Step-by-step explanation:

x=300-y

12x+15y=4140

12(300-y)+15=4140

y=180

substitute

x=300-180

x=120

Answer: 750/500,000

Step-by-step explanation:

you get this because:

the company is giving out 750 hats and there are 500,000 people so you divided those numbers

The Z score is -2 if the standardized exam, the scores are normally distributed with a mean of 21 and a standard deviation of 4.

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have:

u = 21

SD = 4

X = 13

[tex]\rm Z = \dfrac{13-21}{4}[/tex]

Z = -2

Thus, the Z score is -2 if the standardized exam, the scores are normally distributed with a mean of 21 and a standard deviation of 4.

Answer: 1.8 or 180%

Step-by-step explanation:

By using changes of units, we will see that the correct option is d.

We know that the yellow onion weighs 0.59 lb

The red onion weighs 208.65 grams.

The thing we need to do, is write the first mass in grams, then we use:

1 lb = 453.59g

Then we can rewrite:

0.59 lb =  0.59* 453.59g = 267.62g

Then we can see that the red onion is heavier.

The difference in mass is:

m = 267.62g - 208.65g = 58.97g

Now we want to rewrite this in ounces, remember that:

1g = 0.035oz

Then:

58.97g = 58.97*0.035oz = 2.064 oz

Then the correct option must be d.

Step-by-step explanation:

$28,000 - $2,100 = $25,900

$25,900 - $5,000 = $20,900

1.5% × $1,000 = $15

3% × $2,000 = $60

4.5% × $2,000 = $90

5% × $20,900 = $1,045

$15 + $60 + $90 + $1,045 = $1,210

Answer:

x= 7 y=6

Step-by-step explanation:

The slope of line PO and MN is 0.5. And the slope of the line ON and MP is negative 2. Then each length of the quadrilateral is 4.47 units.

It is a quadrilateral with four sides. The total interior angle is 360 degrees.

The points M(−7,2), N(−3,4), O(−5,8), and P(−9,6) form a quadrilateral.

Then the slope of each line of the quadrilateral will be

The slope of the line PO will be

PO = (8-6)/(-5+9)

PO = 2/4

PO = 0.5

The slope of the line ON will be

ON = (8-4)/(-5+3)

ON = 4/(-2)

ON = -2

The slope of the line MN will be

MN = (4-2)/(-3+7)

MN = 2/4

MN = 0.5

The slope of the line MP will be

MP = (6-2)/(-9+7)

MP = 4/(-2)

MP  = -2

Then each length of the quadrilateral will be

The length of PO will be

PO = √[(-9+5)² + (6-8)²]

PO = 4.47

The length of ON will be

ON = √[(-5+3)² + (8-4)²]

ON = 4.47

The length of MN will be

MN = √[(-3+7)² + (4-2)²]

MN = 4.47

The length of MP will be

MP = √[(-9+7)² + (6-2)²]

MP = 4.47
