Answer:

Probability in Maths:-

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.

Formula for Probability:-

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes

Probability refers to a possibility that deals with the occurrence of random events also can be state as all the events occurring need to be 1.

L.C.M = 2 × 7 = 14

Step-by-step explanation:

3ab = 3 × a × b

6b² = 2 × 3 × b × b

7a³b = 7 × a × a × a × b

L.C.M = 2 × 7 = 14

Thus, Lowest common multiple for 3ab; 6b²; 7a³b is 14

stu   pid     i d i o t

Answer:

I don't no the answer sorry

Answer:

A) t=0.2(60.5)

B) d=0.15(34)

C) t=0.9(157.3)

D) p=100(10.49/58.25)

E) t=0.85(94.2+0.2(94.2))

Step-by-step explanation:

A)

Let the tip be represented by t. The tip is 20% of $60.50:

t=0.2(60.5)

B)

Let the money they save be represented by d. Their discount is 15% of $34:

d=0.15(34)

C)

Let the new total be represented by t. Their discount is 10%, so they will only be paying 90% of $157.30t:

t=0.9(157.3)

D)

Let the percentage be represented by p. The tip is $10.49, to find this as a precent of the $58.25 bill, divide the tip by the bill and multiply by 100:

p=100(10.49/58.25)

E)

First find the total after the tip but before the coupon.

Their tip is 20% of $94.20, and their total before the coupon is $94.20 plus the tip: 94.2+0.2(94.2)

Now find their final total.

Let the final total be represented by t. The discount is 15%, so they will only be paying 85% of the total after tip:

t=0.85(94.2+0.2(94.2))

Answer:

2,304 years old

Step-by-step explanation:

Given: Jennifer age = 18, Invested = $1000 at 8% interest

To find: How old would she be when the account is $128,000?

Wrong solution

Solution: To figure out how old she will be when her account is $128,000, simply find the difference between her current account value by her current age, by dividing. Then multiply the result by the future account value.

Step 1: [tex]\frac{1000}{18} = 55.5555555556[/tex]

Rounding, that is; 55.56

Step 2: Now, multiply the result by the future account value.

[tex]55.56[/tex] × [tex]128000 = 7111680[/tex]

Correct solution

Solution: To find out how old she will be when her account is $128,000, set up a fraction;

[tex]\frac{1000}{8} = \frac{12800}{x}[/tex]

Step 1:  Divide the numbers

[tex]\frac{1000}{8} = \frac{128000}{x} \\\\\frac{500}{9} = \frac{128000}{x}[/tex]

Step 2: Multiply all terms by the same value to eliminate fraction denominators

[tex]\frac{500}{9} = \frac{128000}{x} \\\\x * \frac{500}{9} = x * \frac{128000}{x}[/tex]

Step 3:  Cancel multiplied terms that are in the denominator

[tex]x *\frac{500}{9} = x * \frac{128000}{x} \\\\x * \frac{500}{9} = 128000[/tex]

Step 4: Re-order terms so constants are on the left

[tex]x * \frac{500}{9} = 128000\\\\\frac{500}{9} x= 128000[/tex]

Step 5: Combine multiplied terms into a single fraction

[tex]\frac{500}{9} x = 128000\\\\\frac{500x}{9} = 128000[/tex]

Step 6: Multiply all terms by the same value to eliminate fraction denominators

[tex]\frac{500x}{9} = 128000\\\\9 * \frac{500x}{9} = 9 * 128000[/tex]

Step 7: Cancel multiplied terms that are in the denominator

[tex]9 * \frac{500x}{9} = 9 * 128000\\500

Answer:

1.6

Step-by-step explanation:

So, first, write down the number of jokers in each deck of cards.

That would be: 0, 1, 2, 2, 3

Then, add up all those numbers.

0+1+2+2+3=8

Now, divide that sum by the number of decks or cards shown in the data set, which would be 5.

8/5=1.6

So, the mean of the data in the dot plot shown is 1.6.
