If 12 = 17 - 5, then 17 - 5 = 12 What math property is this?

The first and second velocities of the car are 0.25/t1 and 0.50/t2 respectively.

Given data:

The value of the first distance is, d1 = 0.25 m.

The value of the second distance is, d2 = 0.50 m.

The ratio of distance covered by an object in a specific direction and the time taken to cover the distance is known as the velocity of the object. Mathematically, the expression for the velocity is,

v = d/t

Here, d is the distance covered.

And t is the average time taken to cover the distance.

Then the first velocity of the car at 0.25 m is,

v1 = d1/t1

v1 = 0.25 / t1

Here, t1 is the average time for the first distance.

And the second velocity of the car with four washers at the 0. 50 m mark is,

v2 = d2/t2

v2 = 0.50 /t2

here, t2 is the average time for the second distance.

Thus, we can conclude that the first and second velocities of the car are 0.25/t1 and 0.50/t2 respectively.

The equation \(csc2(x) + 6 csc(x) − 7 = 0\) can be rewritten as \(csc(x)(csc(x) + 6) − 7 = 0\). Factorizing the equation we have

Now, solving for csc(x) = 0, we have csc(x) = 0. This implies that x = π/2 or (2n+1)π/2, where n is an arbitrary integer.

Similarly, solving for\(csc(x) + 6 = 0\), we have csc(x) = -6. This implies that \(x = (2n+1)π + arcsec(-6) or (2n+1)π - arcsec(-6)\), where n is an arbitrary integer.

The probability that Lola pulled a red marble first and a yellow marble second is 0.134 or approximately 13.4%.

To calculate the probability that Lola pulls a red marble first and a yellow marble second, we can use the formula:

P(Red, Yellow) = P(Red) x P(Yellow|Red)

where P(Red) is the probability of pulling a red marble first, and P(Yellow|Red) is the conditional probability of pulling a yellow marble second given that a red marble was pulled first.

First, we can calculate P(Red):

P(Red) = number of red marbles / total number of marbles

P(Red) = 4 / (4 + 4 + 12)

P(Red) = 4 / 20

P(Red) = 0.2

So the probability of pulling a red marble first is 0.2.

Next, we can calculate P(Yellow|Red):

P(Yellow|Red) = number of yellow marbles remaining / total number of remaining marbles

P(Yellow|Red) = 12 / (4 + 3 + 11)

P(Yellow|Red) = 12 / 18

P(Yellow|Red) = 0.67

So the probability of pulling a yellow marble second given that a red marble was pulled first is 0.67

Now we can use the formula:

P(Red, Yellow) = P(Red) x P(Yellow|Red)

P(Red, Yellow) = 0.2 x 0.67

P(Red, Yellow) = 0.134

An oil tank is being filled at a constant rate.

In 0 minute, the depth of oil in the tank is 3, : (0,3)

In 10 minute, the depth of oil in the tank is 5, : ( 10, 5 )

In 15 minutes, the depth of oil in the tank is 6, : ( 15, 6 )

Since, the oil is filled at the constant rate, so the equation form by the depth of oil with the time is linear equation.

The general expression for the linear equation is :

Let x express the time and y express the depth of oil

Substitute any two set of value of time and depth from the table : ( 0, 3) & ( 10, 5 )

Since, we need to depth of the oil after, 45 minutes,

Substitute x = 45 in the equation :

as, y represent the depth of the oil

so, depth of the oil is 12 ft in 45 minutes

The general equation of a line is y = mx+b, m being the slope and b the intercept on the y-axis.

We are given the line 7y-4x=-14, let's organize the equation like the general form:

In order to be parallel to your line, a line has to have the same slope as your line. So the slope has to be 4/7.

Thus any line parallel to the line y=4/7x-2 has an equation of the form y=4/7x+b, where b is any number.

By looking at the answer options, we can select the second option y= 4/7x-1

Slope formula - y = mx + b

6x + 2y = 10

subtract x

2y = 10 - 6x

divide all by 2

y = 5 - 3x

y = -3x + 5

5 is the y-intercept, and -3x is the slope

In order to determine the sample size needed to achieve a desired margin of error for the population proportion, you will need to use a formula that takes into account the confidence level, the margin of error, and an estimate of the population proportion (p*).

However, since you do not have a reliable estimate of p*, you can use a conservative estimate of 0.5 to calculate the sample size. This will ensure that you have a large enough sample size to capture any changes in the population proportion, while still maintaining a reasonable level of precision in your estimate. Once you have collected your data, you can use the sample proportion as an estimate of the population proportion in any subsequent analyses.

Answer:

Answer:

(a) The height of the building is 60.06 m

(b) The distance AB is 139.43 m

Step-by-step explanation:

The given parameters are

Given that segment BT = segment AT + 29

By trigonometric ratios, we have;

cos∠ATC = CT/AT

cos∠BTC = CT/BT

Therefore, we have;

cos(40°) = CT/AT.................................(1)

cos(56°) = CT/BT = CT/(AT + 29).....(2)

cos(56°) = CT/(AT + 29)......................(3)

From equation (1)

CT = AT×cos(40°)

From equation (3)

AT×cos(56°) + 29 × cos(56°) = CT

Therefore;

AT×cos(40°) = AT×cos(56°) + 29 × cos(56°)

AT×cos(40°) - AT×cos(56°) =  29 × cos(56°)

AT×(cos(40°) - cos(56°)) =  29 × cos(56°)

AT = 29 × cos(56°)/(cos(40°) - cos(56°)) = 78.4 m

TC = CT = AT×cos(40°) = 78.4×cos(40°) = 60.06 m

The height of the building = 60.06 m

(b) BT = AT + 29 = 78.4 m + 29 m= 107.4 m

AB = AT×sin(∠ATC ) + BT×sin(∠BTC) = 78.4×sin(40°) + 107.4×sin(56°) =  139.43 m

The distance AB =  139.43 m.

The statements which are true for both trigonometric equations y = cos (θ) and y = sin (θ) are:

the function is periodic

the function has a value of about 0.71 when θ = π/4

the maximum value is 1.

The given trigonometric equations are,

y = cos (θ) and y = sin (θ)

The maximum value of sin (θ) = 1 which occurs at θ = 90°, not at θ = 0.

Both the functions sine and cosine are periodic since for both,

f(x) = f(x + θ)

Value of sin (π/4) = cos(π/4) = 1/√2 = 0.707 ≈ 0.71

Maximum value of both functions are 1.

In observational studies, the variable of interest option (a) is not controlled

In observational studies, the variable of interest refers to the data that is being collected and analyzed. It is a specific factor or phenomenon that researchers are looking to gain insight from.

The variable of interest is not controlled by the researcher, meaning that the researcher does not influence the data or manipulate the results in any way; rather the researcher simply observes the data and the phenomenon. The variable of interest could be numerical or non-numerical.

If the interest is in the correlation between gender and academic performance, then this is a non-numerical variable, as gender is not a numerical value.

However, if the interest is in the correlation between hours spent studying and grade point average, then this is a numerical variable, as grade point average is a numerical value.

The two fractions with denominators of 2 and 6 that add up to 19/3 are 3/6 and 29/3, respectively.

First, let's break down what that mixed number means in terms of fractions. 6 1/3 is the same as 19/3.

Now, we need to find two fractions with different denominators that add up to 19/3. One way to do this is to use a common denominator. To find a common denominator, we need to find the least common multiple (LCM) of the two denominators.

Let's say we want to find two fractions that add up to 19/3, with denominators of 2 and 6. The LCM of 2 and 6 is 6. So, we can rewrite the fractions with a denominator of 6:

1/2 = 3/6

x/6

Now we need to find the value of x that makes the sum of the fractions equal to 19/3:

3/6 + x/6 = 19/3

To solve for x, we can multiply both sides by 6:

3 + x = 38/3

Then, we can subtract 3 from both sides:
