Answer:

Given g(x)=4x+6

f(x)=12x+8

f(g(x))=f(4x+6)

=48x+72+8

= 48x+80

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

= $-556.16

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.

The current value of his mortgage must be no higher than $126,360 for him to request termination of his PMI policy.

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.

Given:

Brett bought a house five years ago for $150,000.

At that time he borrowed $140,000 from his bank.

The house is now worth $162,000.

Once his equity has increased to 22% of the current market value he can request that PMI be canceled.

He may request termination of request when his mortgage balance reaches

162,000(1 - 0.22) = 162,000(0.78) = 126,360.

Hence,  the current value of his mortgage must be no higher than $126,360 for him to request termination of his PMI policy.

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.

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.

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
