Step-by-step explanation:

Its basically just simplification btw.

First, let's get the total amount of coins inside the box.

7 quarters + 4 dimes + 4 nickels + 3 pennies = 18 total coins.

(7 quarters / 18 coins) * 100 = 38.89% chance of picking a quarter

(4 dimes / 18 coins) * 100 = 22.22% chance of picking a dime

(4 nickels / 18 coins) * 100 = 22.22% chance of picking a nickel

(3 pennies / 18 coins) * 100 = 16.67% chance of picking a dime

Since the quarters have a higher percentage of being picked, we can expect to draw $0.25 from the box

Step-by-step explanation:

Given the scenario above :

A) State the random variable.

The random variable is the p opoertion of brown M&M's in a milk chocolate packet.

B.) Argue that this is a binomial experiment.

Each trial is independent for a total number of 52 trials with a set probability of success at 0.14

C) probability that 6 M&M's are brown:.

P(x) = nCx * p^x * (1-p)^(n-x)

p = 0.14 ; (1 - p) = 0.86 ; n = 52 ; x = 6

P(x = 6) = 52C6 × 0.14^6 × 0.86^46

= 20358520 × 0.00000752954 × 0.00097035078

= 0.1487

D) P(x =25)

P(x = 25) = 52C25 × 0.14^25 × 0.86^27

= 477551179875952 × 449.987958058*10^(-24) × 0.01703955245

= 0.00000000366

E) P(x = 52)

P(x = 52) = 52C52 × 0.14^52 × 0.86^0

= 1 × 3968.78758299*10^(-48) × 1

= 3968.78758299*10^(-48)

F) yes it would be unusual, because such probability is extremely low. However, if a huge or substantial number of trials such may occur

Answer:

q = r

Step-by-step explanation:

Explanation:-

Given    2q – r = 4p ...(i)

                  2r = q...(ii)

                  r = 2p ...(iii)

Substitute 2r = q in equation (i)

              2(2r) – r = 4p

                     3 r = 4 p

                   2 r + r = 4 p

                   2 r + 2 p = 4 p

                  2 r = 2 p

                   q = r

Answer:

The slope is 2/3

Step-by-step explanation:

Slope is the change in Y over the change in X.

ΔY / ΔX     (That triangle symbol just means the change)

So subtract y2-y1 then x2-x1

-2-(-4) (the two negatives cancel out to a positive so you are left with -2+4)

then 3-0

-2+4= 2

3-0= 3

2/3

Answer: -2

Step-by-step explanation:

We can find the slope  by using

m = (y2-y1)/(x2-x1)

 = (-2 -4)/( 3-0)

 = -6/3

=-2

Answer:

Step-by-step explanation:

The number maybe less than 10, equal to 10, or larger than 10.

Examples:

A.

Answer:

UW=165

Step-by-step explanation:

UV + VW =UW

5x + 8x-17= 11x +11

13x - 17 = 11x + 11

Subtract 11x and add 17 to both sides:

2x= 28

Divide 2 both sides:

x=14

Plug in x to the equation of UW:

11 (14) +11

Answer:

the pre-image is ( -4, 0)

Step-by-step explanation:

Simply apply the appropriate transformation to each coordinate by using the information they give you:

x was converted via the transformation x -1 leading to the value -5,

so we write:

x - 1 = -5

and solve for x:

x = -5 + 1 = -4

y was converted via the transformation y + 2 leading to the value 2, so we write:

y + 2 = 2

and solve for y:

y = 2 - 2 = 0

Therefore the pre-image of the point is: ( -4, 0)

Step-by-step explanation:

Aaron was riding forward, so the position graph should always be sloping upward, with his position always increasing away from home. Lastly, he slowed gradually as he got closer to the school, until he stopped at the bike rack, so the slope of X does not fit. Graph Z best fits this situation.

Answer:

y = 4/3

Step-by-step explanation:

the expression can be written as,

(x^8)^1/3 divided by (x^4)^ 1/3

so by using the rules of powers we can deduce y = 4/3

The rules are,

1. (x^y)^z = X^y*z

2. x^y * x^z = x^ y+z

3. x^y / x^z = x^ y-z

Hence,

8/3 -4/3 = 4/3

Solve this like a normal equation. Pretend the ≤ is an equal sign. Then isolate the variable. Subtract 7 from both sides, and that will give you -4

Answer: $12,697.80

Step-by-step explanation:

To find 15% of $84,652, you want to multiply them together.

0.15×84,652=12,697.80

Now, we know that $12,697.80 is 15% of $84,652.

Answer:

using question mark as reference angle

Base = 13

hypotenuse = 18

usimg trigonometric ratios

cos? = B/h

? = inverse(13/18) = 43.74 = 44°

Step-by-step explanation:

Here, we are given with two sides and the triangle is a right angled triangle. Here, we can use trigonometry to find the missing angle.

According to missing angle, cos theta can be used because we are given with base and hypotenuse. No need to find the perpendicular.

[tex] \cos( \theta) = \frac{base}{hypotenuse} \\ [/tex]

[tex] \cos( \theta) = \frac{13}{18} [/tex]

Now for finding the missing angle theta, inverse of cosine will be applied on the other side. Because, inverse of multiplication is division.

[tex] \theta = \cos {}^{ - 1} ( \frac{13}{18} ) [/tex]

[tex] \theta = \cos {}^{ - 1} (0.7222222222) [/tex]

[tex] \boxed{ \theta \approx \: 43.76174269 \degree}[/tex]

Answer:

20

Step-by-step explanation

not sure but looks like you need help as fast as possible here my answer the way i thought about is you have 70 degree angle and y looks like a right angle which = 90 degree

x = 180 - 70+90

x = 180 - 160

x = 20

The value of the angle x for the given triangle will be 20°.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

As per the given triangle,

m∠y = 90°

The exterior angle = sum of two interior angles except for the adjacent angle of the exterior angle.

110° = x + y

110° = x + 90°

m∠x = 20°

Hence "The value of the angle x for the given triangle will be 20°".

Answer:

17 , 65

Step-by-step explanation:

x+ y = 82

y = 4x - 3

=====================

Put the second equation into the first.

x + 4x - 3 = 82

5x = 85

x = 85/5

x = 17

17 + y = 82

x = 82 - 17

x = 65

Answer:

-25(x - 4) = -55(x - 10)

-25x+100= -55x+550

-25x+55x=550-100

30x=450

x=15

Answer:

x= 15

Step-by-step explanation:

Step 1- Distribute into the parenthesis

-25x-(-25)4= -55x-(-55)10

Step 2- Multiply to simplify

-25x+100= -55x+550

Step 3- Add -55x to both sides

-25x+100= -55x+550

+55x          +55x

Step 4- Subtract 100 to both sides

30x+100= 550

      -100   -100

Step 5- Divide both sides by 30

30x= 450

30     30

x= 15
