The finance charge on the average daily balance for , this 1 month period is $3.45  .

In the question ,

it is given that ,

the daily balance over the period of 1 month = $145

The APR rate of interest = 28.5%

the monthly APR rate of interest = (28.5%)/12 = 2.375%

the finance charge for the 1 month period can be calculated using the formula .

finance charge = (daily average balance)×(monthly rate of interest)

Substituting the values , we get

finance charge = 145 × 2.375%

= 145 × 0.02375

= 3.44375

≈ 3.45

Therefore , The finance charge on the average daily balance for , this 1 month period is $3.45  .

The error interval for m is 6.58 ≤ m < 6.59

Truncation is a process of dropping all decimal places after a certain point without rounding the number.

Given that, the mass, m, of the lorry is 6.58 tonnes truncated to 2 decimal places.

Since the number is truncated to two decimal places, the error interval is,

6.58 ≤ m < 6.59

Hence, the error interval for m is 6.58 ≤ m < 6.59.

Based on the Federal Housing Administration's (FHA) total fixed payments-to-income ratio, Roberto would not qualify for the mortgage loan.

The Federal Housing Administration (FHA) allows 31% of a person's income to settle housing costs (as the front-end ratio) and 43% (as the back-end ratio) towards housing expenses and other long-term debt.

Monthly gross income = $3,500

Monthly payments for Housing:

Monthly mortgage = $1,000

Property taxes = $150

Homeowners insurance premium = $75

Mortgage insurance premium = $75

Total monthly housing costs = $1,300

Other monthly debts per month = $500

Total monthly payments = $1,800

Minimum front-end ratio = 31% = $1,085 ($3,500 x 31%)

Maximum back-end ratio = 43% = $1,505 ($3,500 x 43%)

Thus, using the FHA fixed payments-to-income ratio, Roberto would not qualify.

Answer: 2 real solutions

Step-by-step explanation:

The discriminant is [tex](-9)^2 -4(1)(3)=69[/tex].

Since the discriminant is positive, there are 2 real solutions.

Considering the uniform distribution, we have that:

a) The density curve is given by the image at the end of the answer.

b) The percentage of time in which an enemy will appear between 0.5 minutes and 2 minutes after the timer starts is of 60%.

c) The 20th percentile for the distribution is of 0.75 minutes.

The uniform probability distribution is a distribution with two bounds, given by a and b, in which each possible outcome is equally as likely.

In this problem, the bounds are given as follows:

a = 0.25, b = 2.75.

The height of the density curve is of:

f(x) = 1/(b - a).

Hence:

f(x) = 1/(2.75 - 0.25) = 0.4.

As shown by the image given at the end of the answer.

The probability that a measure is between two values is given by:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

Hence, for item b:

P(0.5 < X < 2) = (2 - 0.5)/(2.75 - 0.25) = 0.6 = 60%.

The 20th percentile is the value of X for which:

X = a + 0.2(b - a).

Hence:

X = 0.25 + 0.2(2.75 - 0.25) = 0.75 minutes.

Answer: 2%

Step-by-step explanation:

First, we know that the experimental value is 13.3, and the true value 13.6. After plugging in, we get |13.3 - 13.6| = -0.3 which is just 0.3 as it is the absolute value. Then, we divide it by 13.6 which brings us the equation 0.3/1.36 which rounds to 0.022. Continuing, we multiply it by 100 which gets our answer of 2.2. The nearest percent is 2, so our answer is 2 percent.

With a correlation coefficient of 0, A. I can’t be confident at all; this is about as close to a random guess as you can get.

A correlation coefficient measures the strength of the linear relationship between two variables.

Correlation coefficients usually range between -1 to 1, and they show how one variable moves in relation to another.

A positive correlation coefficient indicates that the two variables move uniformly in the same direction, while a negative correlation coefficient shows the opposite.

A zero correlation coefficient shows no linear relationship between the two variables.

Thus, if the correlation coefficient is 0, then Option A is correct.

The binomial distribution is a parametric probability distribution with two parameters, X and B. For a large number of trials, n, binomial probability tends to follow a continuous normal probability distribution.

The binomial distribution is a type of probability distribution that models the likelihood of one of two outcomes given a set of parameters. It sums up the number of trials when each trial has the same chance of achieving a single outcome.

Therefore,

The following is the definition of the Binomial distribution's probability mass function:

P (X = x) = (n x)p x(1p)n x, where x = 0, 1, 2, 3,..., n

Given,

Probability of defective, p = 0.03

Number of bulbs, n = 144

(i) The required probability is P(X = 5).

P(X = 5) = (1445) 0.035(1 − 0.03)144 − 5

= 144151 × (144 − 5) 1 × 0.035(1 − 0.03)144 − 5 ≈ 0.169

Within a carton of 144 bulbs, there is a 0.169 percent chance that 5 of them will be defective.

(ii) The required probability is P(X>2).

P(X>2) = 1 − P(X≤2)

= 1 − P(X = 0) − P(X = 1) − P(X = 2)

= 1 − 144101 × (144 − 0)10.030

Then simplifying,

(1 − 0.03)144 − 0 − 14411 × (144 − 1) 10.031 (1 − 0.03)144 − 1 − 14412 × (144 − 2)10.032 (1 − 0.03)144 − 2

= 1 − 0.01245 − 0.0554 − 0.1226

= 0.810

There is a 0.810 percent chance that there will be more than two faulty bulbs in a carton of 144 bulbs.

Answer: $110 but that may be wrong

Step-by-step explanation:

The rate of the boat in still water is 45.5 km/hr and  the rate of the current is 100.5 km/hr.

A motorboat travels 74 km in 2 hours going upstream.

Rate = Distance/time

Rate = 74 /2

Rate = 36 km/hr

It travels 110 km going downstream

Rate = Distance/time = 110/2

Rate  = 55 km/hr

Equations:

Upstream: b-c = 36 km/hr

Downstrm: b+c = 55 km/hr

Add and solve for b

2b = 36 km/hr + 55 km/hr

2b = 91 km/hr

Divide both side by 2b

b = 91 km/hr /2

b = 45.5 km/hr (speed of the boat)

Solve for c

b+c = 55

45.5+ c = 55

c = 55 + 45.5

c = 100.5 km/hr (speed of the current)

Therefore  45.5 km/hr  and  100.5 km/hr are the speed.
