point p moves along a circle that is inscribed inside a square. point q stays fixed at the bottom-left corner of the square. explore this situation in the applet below by dragging the point p along the circle.

Answer:

x = 20

Step-by-step explanation:

x° + 2x° + (x + 10)° = 90° ( complementary angles)

(4x + 10) ° = 90°

4x + 10 = 90

4x = 90 - 10

4x = 80

x = 80/4

x = 20

Answer:

The answer is below

Step-by-step explanation:

The compound interest is given by the formula:

\(A=P(1+\frac{r}{n} )^{nt}\)

Where A is the final amount, p is the principal (initial amount), r is the rate, t is the number of period and n is the number of times it was compounded per period.

Given that:

The interest is compounded yearly, i.e n = 1, for 1 year, t = 1, the compound interest is Rs 450 i.e A = 450. Therefore:

\(450=P(1+\frac{r}{1} )^{1*1}=P(1+r)\\450=P(1+r).\ .\ .\ (1)\)

For 2 year, t = 2, the compound interest is Rs 945 i.e A = 945. Therefore:

\(945=P(1+\frac{r}{1} )^{1*2}=P(1+r)^2\\945=P(1+r)^2.\ .\ .\ (2)\)

Dividing equation 2 by equation 1 gives:

2.1 = 1 + r

r = 2.1 - 1 = 1.1

r = 1.1

Put r = 1.1 in 450 = P(1 + r)

450 = P(1 + 1.1)

450 = 1.11P

P = 405.4

Therefore the rate is 1.1 = 110% and P = Rs 405.4

The work is done on the toy car is 164.4 J .

We are aware that the definition of work is the multiplication of the magnitude of the displacement (d) and the component of the force acting in the displacement direction.

When an object moves over a distance while being applied with force, the work is considered to have been completed.

Three categories can be used to classify the type of labor performed. Positive work, negative work, and zero work are the three types. The angle between force and displacement determines the kind of work that is done. Positive work is defined as any work that causes an object to move in the direction of the applied force.

Given ,

Work = force * distance

Force = 5.2 N

Distance = 32 m

So ,

Work = 5.2 * 32

= 166. 4 J

Therefore the work is done is 164.4 J

Step-by-step explanation:

As the degrees of freedom (DF) increase, the t distribution approaches the normal distribution. Therefore, the correct answer option is: C. normal distribution.

The degrees of freedom (DF) in a sample are typically used to correct a possible bias that exists between the alternative and null hypotheses because they are the maximum number of logically independent numerical values (data points) in the final calculation of a statistical problem.

A normal distribution is sometimes referred to as the Gaussian distribution and it can be defined as a probability distribution that is continuous and symmetrical on both sides of the mean, which shows that all data near the mean have a higher frequency than data that are far from the mean.

In this context, we can reasonably infer and logically deduce that the t-distribution generally approaches the normal distribution as the degrees of freedom (DF) increase.

Answer:

33.1 years

Step-by-step explanation:

Let x be the number of years it takes for the population to reach 49000.

Starting with a population of 19000 and growing at 4.5% per year, the population after t years can be represented by the exponential function:

P(x) = 19000(1 + 0.045)^x

We want to find the value of x that makes P(x) = 49000.

=> 49000 = 19000(1 + 0.045)^x

Dividing both sides by 19000, we get:

=> 2.57895 = 1.045^x

Taking the logarithm of both sides with base 10, we get:

=> log(2.57895) = x log(1.045)

=> x = log(2.57895) / log(1.045)

=> x ≈ 33.1

Therefore, it will take approximately 33.1 years for the population to reach 49000.

If all conditions for inference were met, does the interval provide convincing statistical evidence, at a level of significance of  95%, that the mean number of hours of community service performed last year was indeed different from the recommended 24 hours.

To determine if the 95% confidence interval provides convincing statistical evidence at a level of significance that the mean number of hours of community service performed last year was different from the recommended 24 hours, we'll analyze the constructed interval (20.37, 23.49).
1. First, observe the given confidence interval: (20.37, 23.49)
2. Identify the recommended average of 24 hours by the president.
3. Check if the recommended average is within the confidence interval.
Since 24 hours is not within the interval (20.37, 23.49), it provides convincing statistical evidence, at a level of significance of 95%, that the mean number of hours of community service performed last year was indeed different from the recommended 24 hours.

To find the area of a rectangle, we multiply its length by its width. In this case, the length is given, but the width is missing, represented by the variable x.

The equation to find the area of a rectangle is: Area = Length × Width.

In this case, the length is given and is 18. So the equation becomes: Area = 18 × Width.

To solve for x, we need to isolate it on one side of the equation. Since we want to find an equivalent equation for x, we need to rewrite the equation to solve for x.

To isolate x, we need to divide both sides of the equation by 18. This cancels out the 18 on the right side, leaving us with x on the right side:

Area/18 = Width.

This equation is equivalent to the original equation for x and represents the width of the rectangle.

In summary, an equivalent equation for x in the given problem is: Area/18 = Width.

Subtract 7 from both sides to get the answer.

Since both sides of the equation are equal, we have completed the basic step of the proof, showing that P(1) is true.

a.) The statement P(1) is obtained by substituting n=1 into the equation. So, P(1) would be: 1³ = (1(1 + 1) / 2)²

b.) To show that P(1) is true, we need to prove that both sides of the equation are equal:

Left side: 1³ = 1

Right side: (1(1 + 1) / 2)² = (1(2) / 2)² = (2 / 2)² = 1² = 1

The answer to your question is Marissa = 6, Trevor = 16

Step-by-step explanation:

Data

total number of t-shirts = 26

Marissa has 6 fewer than trevor

Process

1.- Write equations to solve this problem

Marissa = m

Trevor = t

                     m + t = 26                Equation l

                      m = t - 6                  Equation ll
