Next step is to Mark off your new arc with this new width by positioning the compass point on the reference line where the previous arc crossed it.

Steps to be followed while measuring an exact angle using compass and straight edge are:

Swing the arc so that the pencil crosses BOTH rays (sides) of the angle. Holding the compass point at the starting point (dot) on the reference line, swing an arc that will cross the reference line and rise above the reference line without adjusting the compass's size. Return to the supplied angle ABC and determine the span (width) of the arc between the points at which it crosses one side of the angle and the other. Mark off your new arc with this new width by positioning the compass point on the reference line where the previous arc crossed it. Join this new intersection point to the reference line's starting point. Mark the duplicate.

The time taken by the person to cover 260 miles will be 3 hours and 15 minutes.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Given that a person to drive 260 miles on a highway if she merges onto a highway at 7 p.m. and drives nonstop with her cruise control set at 80 mph.

The amount of time taken by the person to cover the distance of 260 miles with a speed of 80mph is,

Speed = Distance / Time

Time = Distance / Speed

Time = 260 / 80

Time = 3.25 or 3 hours 15 minutes

Therefore, the time taken by the person to cover 260 miles will be 3 hours and 15 minutes.

Step-by-step explanation:

Answer: If a superball is dropped from a height of h feet and left to bounce forever, the total time needed for all this bouncing to take place can be represented by the formula:

t = h / (r - 1)

where t is the total time, h is the height from which the ball is dropped, and r is the rebound ratio of the ball.

The rebound ratio of the ball is the fraction of the ball's initial height that it bounces back up after each bounce. For example, if a ball has a rebound ratio of 0.5, it will bounce back up to half its initial height after each bounce.

The total time needed for the ball to bounce forever is equal to the height from which the ball is dropped divided by the difference between the rebound ratio and 1. This is because the ball will bounce back up a fraction of its initial height after each bounce, and the total time needed for all the bounces to take place is determined by the difference between the height of the ball and the fraction of the height that it bounces back up.

The expressions that are equivalent to [tex]\frac{10}{9} + \frac{2}{9}m - \frac{4}{9}n[/tex] are [tex]\frac{2}{9}(5 + m -2n)[/tex] and [tex]-\frac{2}{9}( 2n -m -5)[/tex].

Algebraic fractions are fractions using a variable in the numerator or denominator, such as . Because division by 0 is impossible, variables in the denominator have certain restrictions. The denominator can never equal 0.

    [tex]\frac{10}{9} + \frac{2}{9}m - \frac{4}{9}n[/tex] in this algebraic fraction 2/9 is common to all so factoring that out we have

2/9 x 5 + 2/9 x m - 2/9 x 2n so we factor out 2/9

2/9( 5 + m -2n)

This can also be written by multiplying 2/9( 5 + m -2n) by -1 so that it 5becomes

- 2/9(2n -5 - m)

In conclusion the expressions 2/9( 5 + m -2n) and - 2/9(2n -5 - m) are equivalent to [tex]\frac{10}{9} + \frac{2}{9}m - \frac{4}{9}n[/tex]

What is mortgage value?

The appraised value of the property used to determine the mortgage value is determined by a reputable firm. It might not match the purchase-sale value. The mortgage value, which serves as the Bank's guarantee, is the benchmark used in the mortgage application and arrangement process.

The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena.

The required details for null hypothesis in given paragraph

The null hypothesis and alternative hypothesis in this case would be:

H₀: The distribution of hockey players' birth months is uniformly distributed.

H₁: The distribution of hockey players' birth months is not uniformly distributed.

The expected counts for each birth month can be calculated as follows:

Expected Count = (Total Number of Players) * (Proportion of Total Players for Each Birth Month)

Since there are 4 birth months and the distribution is assumed to be uniform, the proportion of total players for each birth month is 1/4 = 0.25. Therefore, the expected count for each birth month is:

Expected Count = 188 * 0.25 = 47

To test the null hypothesis, we can then calculate the chi-square statistic using the following formula:

χ² = ∑((O - E)² / E)

where O is the observed count, E is the expected count, and the sum is taken over all birth months.

Plugging in the observed and expected counts, we get:

χ² = ((66 - 47)² / 47) + ((59 - 47)² / 47) + ((34 - 47)² / 47) + ((29 - 47)² / 47)

= 3.87 + 2.04 + 3.87 + 5.57

= 15.35

In this case, df = 3.

Looking up the critical value in the chi-square table with df = 3 and a = 0.05, we find that the critical value is 7.815. Since the chi-square statistic (15.35) is greater than the critical value, we reject the null hypothesis and conclude that there is evidence to suggest that the distribution of hockey players' birth months is not uniformly distributed.

Given,

Cost of theme park is = $20

Tickets for each ride and attraction are = $3 a piece

Number of tickets purchased = X

So, total cost of tickets is = 3 * X

Total cost of visit to the theme park is = Y

So, the equation we get

Y = 3X + 20

To find the percent of change, we need to calculate the difference between the original price and the new price, and then divide this difference by the original price and multiply by 100%.

The difference between the original price of $20 and the new price of $55 is $55 - $20 = $35.

The percent of change is: ($35/$20) * 100% = 1.75 * 100% = 175%

Since the new price is higher than the original price, this is an increase. Therefore, the percent of change is a 175% increase. The correct answer is therefore

O 175% increase.

You owe $31000 on student loans at an interest rate of 3.35% compounded monthly.

Generally, To calculate the monthly payment amount, you can use the following formula:

monthly payment = (interest rate / 12) x (loan balance / (1 - (1 + (interest rate / 12)) ^ (-term in months)))

Plugging in the values given in the question, the monthly payment would be:

monthly payment = (3.35% / 12) x ($31000 / (1 - (1 + (3.35% / 12)) ^ (-8 years x 12 months/year)))

= (0.00335) x ($31000 / (1 - (1 + 0.00335) ^ (-96)))

= $318.54

So the monthly payment would be $318.54.

To calculate the total interest paid over the course of the loan, you can use the following formula:

total interest = (monthly payment x term in months) - loan balance

Plugging in the values given in the question, the total interest paid would be:

total interest = ($318.54 x 96 months) - $31000

= $30,443.84 - $31,000

Given that P(E)= 0.30 and P(F)= 0.47, the probability of P(E or F) if E and F are mutually exclusive will be 0.77.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Here,

P(E)=0.30

P(F)=0.47

P(E∩F)=0 as they are mutually exclusive

P(E∪F)=P(E)+P(F)-P(E∩F)

=0.30+0.47

P(E∪F)=0.77

The probability of P(E or F) if E and F are mutually exclusive will be 0.77 given that P(E)= 0.30, and P(F) = 0.47.
