the probability that a person will miss the bus is 0.4, find the probability that on two consecutive morning, he will miss the bus at least one morning​

Answer:

Option C.

Step-by-step explanation:

Gross pay = (total hours works) * pay rate

                 = (4.7 + 7.3 + 6.4 + 5.8 + 5.4) * 12.1

                 = 29.6 * 12.1

                 = $358.16

This number is closest to 354.53, so C is the correct answer.

The angles 45 degrees, 30 degrees, and 105 degrees do not form a valid triangle.

In a triangle, the sum of the angles must be 180 degrees. However, in this case, the sum of the three angles is:

45 + 30 + 105 = 180

This tells us that these three angles can be arranged in a straight line, but they cannot form a triangle.

In a valid triangle, the sum of the two smaller angles must be greater than the measure of the largest angle. However, in this case, the sum of the two smaller angles (30 degrees and 45 degrees) is only 75 degrees, which is less than the measure of the largest angle (105 degrees).

Based on the above, the equivalent equations are 4x = 15 and 4x - 15 = 0.Hence options A and C are correct.

To determine which equations are equivalent to 3x + 5 = 20 - x, we need to simplify and manipulate the original equation until it has the same form as the other equations. Here's how we can do it:

3x + 5 = 20 - x

Add x to both sides:

4x + 5 = 20

Subtract 5 from both sides:

4x = 15

The determinant of the given matrix is -51.

A square matrix's related scalar value is known as a determinant. It is calculated based on the matrix's components using a specified formula. The determinant has several uses in linear algebra, including the resolution of systems of linear equations, the discovery of eigenvalues and eigenvectors, and the assessment of invertibility. If and only if a matrix's determinant is nonzero, the matrix is invertible. The determinant is also employed in other branches of mathematics, such as differential geometry and the determination of the volume of parallelepipeds.

The determinant of the matrix is calculated using the formula:

D = a(ei - fh) - b(di - fg) + c(dh - eg)

Substituting the values we have:

3(-20 - 5(-1)) - (-1)(20 - 54) + 4(2*(-1) - (-2)*(-1)) = -51

The length, breadth, and height of the rectangular block are 256 cm, 192 cm, and 320 cm respectively.

To calculate the length, breadth, and height of a rectangular block whose ratio is 4:3:5 and its volume is 3840 cm3,

follow the steps below:

The ratio of length, breadth, and height is 4:3:5 respectively.

Therefore, assume the length to be 4x, the breadth to be 3x, and the height to be 5x, where x is the common factor.

Then, the volume of the block is calculated as:

Volume = length × breadth × height= 4x × 3x × 5x= 60x³

Since the volume of the block is 3840 cm³, we can equate the equation above to 3840 and solve for x, then find the

length, breadth, and height.

60x³ = 3840 x³ = 3840/60 x³ = 64

Length = 4x = 4 × 64 = 256 cm

Breadth = 3x = 3 × 64 = 192 cm

Height = 5x = 5 × 64 = 320 cm

With given coordinates of the endpoints of line, the length is 17.75 units.

What are coordinates ?

Coordinates are a set of numbers that describe the position or location of a point in space. In a two-dimensional plane, coordinates are typically represented by two values, an x-coordinate and a y-coordinate, which describe the horizontal and vertical position of a point, respectively.

Now,

The length of a line segment in a two-dimensional plane can be calculated using the distance formula:

d=√[(x₂ - x₁)² + (y₂ - y₁)²]

where (x₁, y₁) and (x₂, y₂) = coordinates of the endpoints of the line segment

In this case, the coordinates of the endpoints are (4.25, 6.25) and (22, 6.25)

d = √[(22 - 4.25)² + (6.25 - 6.25)²]

= √[(17.75)² + (0)²]

= √(315.0625)

= 17.75

Answer:To divide -5 by 1,000, we can use a calculator or perform long division.

Using a calculator, we get -0.005 as the result.

To perform long division, we can follow these steps:

1. Write -5 as the dividend and 1,000 as the divisor.

2. Place the divisor outside the long division bracket and the dividend inside the bracket.

3. Divide the first digit of the dividend by the divisor. In this case, 1,000 does not go into -5, so we write 0 as the first digit of the quotient.

4. Bring down the next digit of the dividend (which is 0) and place it next to the 0 in the quotient.

5. Divide 1,000 into 0, which gives 0 as the next digit of the quotient.

6. Continue bringing down digits from the dividend and dividing until you have enough decimal places in the quotient. In this case, we can stop after two decimal places because we know the answer is not 200.

7. The final result is -0.005.

Therefore, -5 divided by 1,000 is equal to -0.005.

The total price Briana will pay for the sweater after discount is $34.2.

What is discount?

Discount is the state of having a bond's price lower than its face value. The difference between the purchase price and the item's par value is the discount.

Discounts are different types of price reductions or deductions from a product's cost. It is frequently employed in consumer transactions when consumers receive discounts on a range of goods. The % discount rate is provided.

Here the Sale price of sweater on sale = $45

Discount = 30%

Sale tax rate = 6%

If cost is 100% , after 30% discount and 6% sale tax rate then ,

cost price = 100%- 30%+6% = 70%+6%=76%

Now cost price = 76% of 45

=> 76%×45

=> 76/100 ×45

=>$34.2

Hence the  total price Briana will pay for the sweater is $34.2.

Standard deviation = sqrt(variance) = sqrt(40,000) = 200

z = (x - μ) / σ

where z is the standardized value, x is the value of interest, μ is the mean, and σ is the standard deviation.

For x = 1000:

z1 = (1000 - 1100) / 200 = -0.5

For x = 1520:

z2 = (1520 - 1100) / 200 = 2.1

Using a calculator, we can use the normal cdf function with the z-scores to find the area between z1 and z2:

P(z1 < z < z2) = normal cdf(-0.5, 2.1) ≈ 0.9192

Rounding to four decimal places, we get:

Given that √7 is a solution to the equation x² = 7, we can use this equation to find a decimal approximation of √7 that satisfies the given condition.

First, we can estimate that √7 is between 2.5 and 3, since 2² = 4 < 7 and 3² = 9 > 7.

Next, we can try using a decimal approximation of √7, such as 2.6 or 2.7, and square it to see if the result is between 6.9 and 7.1.

If we try 2.6, we get:

(2.6)² = 6.76

Since this is less than 6.9, we can try a larger value, such as 2.7:

(2.7)² = 7.29

Since this is greater than 7.1, we can try a value between 2.6 and 2.7, such as 2.65:

(2.65)² = 7.0225
