Sue travels by bus or walks when she visits the shops. The probability that she catches the bus to the shops is 0.4. The probability she catches the bus from the shops is 0.7. Show the probability that Sue walks at one way is 0.72

Answer:

\(P(A \cup B) =0.72\) (Proved)

Step-by-step explanation:

Sue travels by bus or walks when she visits the shops.

Let the event that she catches the bus to the shop=A

Let the event that she catches the bus from the shop=B

P(A)=0.4

P(B)=0.7

Both A and B are independent events.

Therefore,Probability that she catches the bus to and from the shop:

P(A∩B) = 0.4 X 0.7= 0.28

Probability Sue walks at least one way \(P(A \cup B) = 1 - P(A \cap B)\)

\(= 1 - 0.28\\= 0.72\)

Hence, the probability that Sue walks at least one way is 0.72.

Answer:187.5

Step-by-step explanation: I am bad at explaining but il try.

if 1/2x = 75y, that means 1x = 150. 1/4x is 1/2x divided by 2 which is 37.5.

2 1/4 is two 150 and one 37.5 so the awnser should be 187.5.

The length of the diagonal of a 7 cm × 6 cm × 12 cm rectangular prism is 9.2 cm.

To find the length of the diagonal of a rectangular prism, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the diagonal of the rectangular prism is the hypotenuse, and the other two sides are the length and width of the rectangular prism.

So, we can use the following formula to find the length of the diagonal:

Diagonal = √(length² + width²)

In this case, the length and width of the rectangular prism are 7 cm and 6 cm, respectively. So, we can plug these values into the formula to find the length of the diagonal:

Diagonal = √(7² + 6²)

= √(49 + 36)

= √85

= 9.2 cm (rounded to the nearest tenth)

Complete Question:

The amount of money, y, pizzeria W makes by selling x pizzas can be modeled by the equation y = 15x. The relationship of the amount of money pizzeria L makes is shown in the following graph.

Which pizzeria makes more money per pizza?

A. Pizzeria L makes more money per pizza.

B. Pizzeria W makes more money per pizza.

C. They make the same amount per pizza.

Answer:

B. Pizzeria W makes more money per pizza.

Step-by-step explanation:

The proportional relationship showing how amount of money made(y) is related to the amount of pizzas sold (x) for pizzeria W is given by the equation y = 15x.

the constant of proportionality/unit rate, k = 15.

This represents the amount in dollars, made per pizza.

So, Pizzeria W makes $15 per pizza.

For Pizzeria L, using any point on the line, say, (2, 24),

k = y/x = 24/2 = 12.

This represents the unit rate, which is the amount Pizzeria L makes per pizza.

Thus, Pizzeria L makes $12 per pizza.

We can conclude that, Pizzeria W makes more money per pizza.

Answer:

y = 6x + 3

Step-by-step explanation:

6x - y = 1

y = 6x + 3

The solution to each of the arithmetic sequence are:

1) a₁₀ = 56

2) a₁₀ = 87

3) missing term is 13

4) missing term is 14

The formula for the nth term of an arithmetic sequence is:

aₙ = a + (n - 1)d

where:

a is first term

n is nth term

d is common difference

1) a = 2

d = 6

a₁₀ = 2 + (10 - 1)6

a₁₀ = 2 + 54

a₁₀ = 56

2) a = 15

d = 8

a₁₀ = 15 + (10 - 1)8

a₁₀ = 87

3) The missing term will be gotten by finding the common difference.

d = (22 - 4)/2

d = 18/2

d = 9

missing term = 4 + 9 = 13

4) The missing term will be gotten by finding the common difference.

d = (53 - 25)/2

d = 28/2

d = 14

missing term = 4 + 9 = 14

The required measure of an angle is 73 degrees which supplement is 253.

The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.

The supplement of an angle is equal to 180 degrees minus the angle.

So if we call the angle "x", we can set up an equation as follows:

2x + (180 - x) = 253

Simplifying the equation:

x = 253 - 180

Apply the subtraction operation, and we get

x = 73

So the angle is 73 degrees.

The simplified expression is as follows;

The error was made because you didn't multiply the powers.

The expression can be simplified as follows;

\((x^{\frac{3}{5} } )^{\frac{7}{5} }\)

Using the law of indices,

If a base variable is raised to a number (y) and the entire number raised to power (x), then it is equal to the base number raised to the multiplication of the two exponents (x × y) i.e.

Hence,

\((A^{x} )^{y} = A^{xy}\)

Therefore, let's apply the rule,

\((x^{\frac{3}{5} } )^{\frac{7}{5} } = x^{\frac{3}{5}.\frac{7}{5} }\)

Hence,

\((x^{\frac{3}{5} } )^{\frac{7}{5} } = x^{\frac{3}{5}.\frac{7}{5} } = x^{\frac{21}{25} }\)

Therefore, using the law of indices,

\((x^{\frac{3}{5} } )^{\frac{7}{5} } = x^{\frac{21}{25} }\)

The error was that he did not multiply the exponents.

The required answer to the subtraction problem 83,456 - 728.88 is, 82,727.12

Subtraction is mathematical terminology that helps and elaborates the decrease in the original value by some value.

Here,
To perform the subtraction, you line up the decimal points and subtract the digits in each place value starting from the right. In this case, you subtract 8 from 6, which requires borrowing 1 from the digit to the left, giving you 16 - 8 = 8 in the one's place. You then subtract 2 from 5, giving you 3 in the tenth place. Continuing this process, you get the result of 82,727.12.

There are 45,697,600 different number of plates that can be issued using this configuration.

To determine the number of different license plates that can be issued using the given configuration, we need to consider the number of options for each component of the license plate.

1. Letters (first two letters): Each letter can be any uppercase letter of the alphabet.

There are 26 letters in the English alphabet, so there are 26 options for each letter.

Since we have two letters, the total number of options for the first two letters is 26 * 26 = 676.

2. Digits (two digits): Each digit can be any number from 0 to 9, so there are 10 options for each digit.

Since we have two digits, the total number of options for the digits is 10 * 10 = 100.

3. Letters (last two letters): Similar to the first two letters, there are 26 options for each letter.

Therefore, the total number of options for the last two letters is also 26 * 26 = 676.

To find the total number of possible license plates, we multiply the number of options for each component:

Total number of license plates = (Number of options for letters) * (Number of options for digits) * (Number of options for letters)

Total number of license plates = 676 * 100 * 676

Total number of license plates = 45,697,600
