Answer:

A Man Drove Solo Across America in 25 Hours 55 Minutes in a Rental Mustang

Step-by-step explanation:

Answer:

a). m∠a = 62°

b). m∠b = 118°

Step-by-step explanation:

a). Since, an angle inscribed in a semicircle is a right angle,

   m∠ACB = 90°

   By triangle sum theorem in ΔABC,

   m∠CAB + m∠ACB + m∠ABC = 180°

   28° + 90° + m∠ABC = 180°

   118° + m∠ABC = 180°

   m∠ABC = 180°- 118°

   a = 62°

b). Since, quadrilateral ABCD is a cyclic quadrilateral,

    m∠ADC + m∠ABC = 180°

    b + a = 180°

    b + 62° = 180°

    b = 180° - 62°

    b = 118°

The distance of the base of the ladder to the base of the building is 22.8 ft

The situation forms a right angle triangle.

Right angle triangle has one of its angle as 90 degrees. The sides and angles can be found using trigonometric ratios. Therefore,

The length of the ladder is the hypotenuse of the triangle formed.

The distance of the base of the ladder to the base of the building is the adjacent sides.

Therefore,

cos 18 = adjacent / hypotenuse

cos 18 = a / 24

cross multiply

a = 24 cos 18

a = 22.8253563911

Therefore, the distance of the base of the ladder to the base of the building is 22.8 ft

Probability theory is a branch of mathematics that measures the probability that an event or statement is true. The probability of an event is a number between 0 and 1, with approximately 0 indicating that the event is unlikely and 1 indicating that it is certain. Probability is a numerical representation of the disease that a particular event will occur. Another way to express probability is as a percentage from 0% to 100% or 0 to 1. Proportion of occurrences in the complete set of equally likely possibilities leading to a particular occurrence compared to the total number of outcomes.

Answer:

19

Step-by-step explanation:

Since the median is 18, we know that the missing number must be between 17 and 21. To find their average, we add them together and divide by 2:

(17 + 21) / 2 = 19

Answer: Never(!) [assuming I understand/interpret the question properly]

Step-by-step explanation: The question wants to know how many months it will take for your neighbor's total cost be the same as yours, with three televisions. One has to interpret "total cost." I deem it to be the total accumulated costs, including installation. If you interpret it as the cost per month, then they charges are the same after the month the installation cast was paid. That's because the satellite provider charges per television, and 3*(13.32) is equal to the same 39.96/month charged by the cable provider. It the questions means total cumulative costs, the satellite customer will never exceed the cable customer's total bill, because of the installation fee ($75 for cable and free for satellite)

Approximately 68% of callers are on hold between 2.6 and 3.4 minutes. To find the per cent of callers on hold between 2.9 and 4.4 minutes, we need to find the area under the normal distribution curve between these two values.

Using a standard normal distribution table or calculator, we can find the z-scores for 2.9 and 4.4, which are -0.63 and 1.5, respectively. Then, we can use the cumulative distribution function (CDF) to find the area under the curve between these z-scores. The result is approximately 65.6%. Therefore, we can conclude that about 65.6% of callers are on hold between 2.9 and 4.4 minutes.

To explain the calculation in more detail, we can use the formula for the standard normal distribution, which is:

z = (x - μ) / σ

where z is the z-score, x is the value we are interested in, μ is the mean, and σ is the standard deviation. Using the given values, we can find the z-scores for 2.9 and 4.4 as follows:

z1 = (2.9 - 3.4) / 0.8 = -0.63

z2 = (4.4 - 3.4) / 0.8 = 1.25

We need to use the CDF to find the area under the curve between these two z-scores. The CDF gives the probability that a random variable is less than or equal to a certain value. We can use a standard normal distribution table or calculator to find the CDF for each z-score.

The CDF for z1 is approximately 0.2643, and the CDF for z2 is approximately 0.8944. To find the area between these two values, we subtract the smaller CDF from the larger CDF:

0.8944 - 0.2643 = 0.6301

This means that about 63.01% of the area under the normal distribution curve is between z1 and z2. However, we are interested in the per cent of callers who are on hold between 2.9 and 4.4 minutes, not the per cent of the area under the curve. To convert this percentage to the per cent of callers, we can multiply by 100:

0.6301 * 100 = 63.01%

Therefore, approximately 65.6% of callers are on hold for between 2.9 and 4.4 minutes.

Answer:

2,678,400

Step-by-step explanation:

July : 31 days

Day : 24 hours

Hours : 60 minutes

Minute 60 seconds

1. 60 × 60 : 3600

2. 3600 × 24 : 86400

3. 86400 × 31 : 2678400

Pls like I got it wrong the first time :')

The month of July has 2,678,400 seconds as per the concept of multiplication.

To calculate the number of seconds in the month of July, we need to consider that each day has 24 hours, each hour has 60 minutes, and each minute has 60 seconds. Since July has 31 days, we can perform the following calculations:

Number of hours in July: 31 days x 24 hours = 744 hours.

Number of minutes in July: 744 hours x 60 minutes = 44,640 minutes.

Number of seconds in July: 44,640 minutes x 60 seconds = 2,678,400 seconds.

Therefore, the month of July has 2,678,400 seconds. This calculation assumes that there are no leap seconds added during this period. It's worth noting that the number of seconds in a month can vary if leap seconds are inserted to adjust for discrepancies between atomic time and solar time. However, since the question does not specify any leap seconds, the calculation provided represents the standard number of seconds in the month of July.

Answer:

x = 6 cm

Step-by-step explanation:

We can write equations for length and width using the information given:

length = 2 + x

width = 2x - 5

Area = (length)(width) = 56

Area = (2 + x)(2x - 5) = 4x - 10 + 2x² - 5x

Simplifying:

Area = 2x² - x - 10 = 56

2x² - x - 66 = 0

Factoring:

(2x + 11)(x - 6) = 0

x = 6, -11/2

We choose the positive number: x = 6 cm

To check, plug in 6 for x:

Area = (2 + x)(2x - 5) = 56

(2 + 6)(12 - 5) = 56

(8 × 7) = 56

56 = 56

edit: So when doing scientific notation, you just divide the important first number of 9.3 or whatever by 3.1 like normal.

Then, when doing exponents, heres a rule of thumb.

When adding exponents, the base must be the same.

9.3 ^ 100  +  9.3 ^ 3  =  9.3 ^103

9.3 ^ 29 + 4.4 ^ 54 = cannot be solved

When subtracting exponents, the same rule applies as adding, the bases must be the same, otherwise, you just subtract or add like normal.

When dividing exponents, you just subtract exponents. The bases must be the same though of course.

3 ^ 30

----------

3 ^ 20

====  3 ^ 10

When multiplying exponents, you add exponents like normal. Bases are the same ect.

4 ^ 49    x    4 ^ 2   =   4 ^ 51

When doing scientific notation, the same rule applies.

The 10 is the base, so in your case, you divide the 9.3 and 3.1 like normal to get 3.

The exponent by the 10 is subtracted to get 17 since 34 - 17 = 17.

The area between z=1.1 and z=2.1 is approximately 0.982 - 0.864 = 0.118, rounded to three decimal places.

To find the area below z=1.04 for an Upper N(0,1) density, you will need to use the standard normal distribution table or a calculator with a z-table function. Here are the steps:

1. Locate the value of z=1.04 in the table or use the calculator's function.
2. Find the corresponding area value (which represents the probability or percentage of values below z=1.04).

The area below z=1.04 is approximately 0.851, rounded to three decimal places.

(b) To find the area above z=-1.4 for an Upper N(0,1) density, follow these steps:

1. Locate the value of z=-1.4 in the table or use the calculator's function.
2. Find the corresponding area value.
3. Since we need the area above z=-1.4, subtract the area value found in step 2 from 1.

The area above z=-1.4 is approximately 1 - 0.0808 = 0.919, rounded to three decimal places.

(c) To find the area between z=1.1 and z=2.1 for an Upper N(0,1) density, follow these steps:

1. Locate the values of z=1.1 and z=2.1 in the table or use the calculator's function.
2. Find the corresponding area values for both z=1.1 and z=2.1.
3. Subtract the area value of z=1.1 from the area value of z=2.1 to find the area between them.

The area between z=1.1 and z=2.1 is approximately 0.982 - 0.864 = 0.118, rounded to three decimal places.

Answer:

  1.6

Step-by-step explanation:

You want the ratio of the side of a square to the radius of a circle that is tangent to one side and passes through the end points of the opposite side of the square.

The radius of the circumcircle of the isosceles triangle inscribed in a square is 5/8 of the length of the side of the square. This is seen in the attached figure, which is drawn to scale.

For a unit square located so the midpoint of the top side is the origin, the bottom right corner is located at (1/2, -1). The perpendicular bisector of the line segment between the origin and that point will have the equation ...

  y+1/2 = 1/2(x -1/4)

The y-intercept of this line is the opposite of the circle's radius:

  y = 1/2x -5/8

The circle radius is 5/8.

The ratio of side length to radius is ...

  s/r = 1/(5/8) = 8/5 = 1.6 . . . . exactly
