Answer:

Step-by-step explanation:

The perimeter is all the side lengths added together so we get

Perimeter = 3 + 7.6 + 7 + 7 + 7 = 31.6

The area is the area of the triangle on top plus the area of the square on the bottom, so:

Area = \(\frac{1}{2} *3*7.6 + 7*7\) = 11.4 + 49 = 60.4

Answer:

Step-by-step explanation:

total interest paid is given as $4,643.46.

total payments = $429.95 x 36 months = $15,478.20

total lease payments = total payments - total interest

total lease payments = $15,478.20 - $4,643.46 = $10,834.74

Remaining balance = Total cost of the lease - Total lease payments

$23,495 - $10,834.74 = $12,660.26

The value of x is 30 degrees as it is a complimentary angle. When two angles' measurements add up to 90 degrees, they are said to be complimentary. When two angles' measures sum up to 180 degrees, they are said to be supplementary.

Complementary angles are two angles with a combined angle of 90 degrees, whereas supplementary angles have a combined angle of 180 degrees.

Reflex angles are those that are larger than 180 degrees and less than 360 degrees. So 270 degrees is a reflex angle.

Since it is a right angle triangle,

hence

\((2x+1)+29=90\\2x+1=61\\2x=60\\x=30\)

On solving the provided question, we can say that Probability(A and B) = P(A)P(B|A) and P(E or F) = P(E) + P(F) - P(E and F)

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

Probability(A and B) = P(A)P(B|A).

P(A and B) = P(B and A), this may also be written as P(A and B) = P(B)P(A|B).

Using the general multiplication rule, we have

P(E and F) = P(E)P(F|E)

.392 = P(E)(.7)

P(E) = .56

   P(E and F) = P(F)P(E|F)

.392 = P(F)(.56), so

P(F) = .7

P(E or F) = P(E) + P(F) - P(E and F)

Step-by-step explanation:

We have shown that C is the image of A by dilation with center B and ratio 3.

Now, To show that C is the image of A by dilation with center B and ratio 3, we need to follow these steps:

Firstly, Find the vector AB by subtracting the coordinates of B from the coordinates of A:

AB = A - B = (6 - 3, 4 - 7) = (3, -3)

Multiply the vector AB by the dilation ratio of 3:

3 AB = 3 (3, -3)  = (9, -9)

Add the resulting vector to the coordinates of the center B:

BC = B + 3 AB = (3, 7) + (9, -9)

BC = (12, -2)

Hence, Compare the resulting point BC to the coordinates of C to show that they are the same:

BC = (12, -2) = C

Therefore, we have shown that C is the image of A by dilation with center B and ratio 3.

The error interval for car and person are:

2275 ≤ 2276 < 2276.5 and 60.55 ≤ 60.6 < 60.65 respectively.

Given, the mass of a car is 2276 kg.

we are asked to determine the nearest kilogram.

the car: rounded to the nearest kilogram

so 2275 ≤ 2276 < 2276.5

therefore, a = 2275.5

and b = 2276.5

The mass of a person is 60.6 kg.

we need to round it to 1 decimal place.

the person: rounded to 1 decimal place,

so, 60.55 ≤ 60.6 < 60.65

therefore, a = 60.55

and b = 60.65

Hence the error interval for the combined mass, m, of the car and the person is 2275 ≤ 2276 < 2276.5 and 60.55 ≤ 60.6 < 60.65 respectively.

The amount of time he spent on bicycle is 4.5 hours.

Given Jim began a 145 mile bicycle trip.

The whole trip took 7 hours.

Jim walks at a rate of 4 miles per hour  and rides at 30 miles per hour.

speed = distance / time

time = distance / speed

ride:

d = distance ridden

t = d/30 (given from the problem)

walk:

t = (145 - d)/4 (given from problem)

total trip time:

7 = d/30 + (145 - d)/4.

7 = 4d/120 + 30(145 - d)/120

7×120 = 4d + 30(145 - d)

840= 4d +4350-30d

840 ₋ 4350 = ₋30d ₊ 4d

₋3510 = ₋26d

d = 3510/26

d = 135

d=135 then from here using the formula t = d / s we can solve

t=135/30 = 4.5 hours

Step-by-step explanation:

If you made a profit by selling it then you got more money in return.

Could I please have BRAINLIEST.

Answer:

Step-by-step explanation:

a) The point estimate of the population variance is 900 (rooms squared).

b) The 90% confidence interval estimate of the population variance is approximately (486, 1706) (rooms squared).

c) The 90% confidence interval estimate of the population standard deviation is approximately (22.0, 41.3) rooms.

a. The point estimate of the population variance can be calculated using the formula:

Point estimate of population variance = Sample standard deviation squared

= (30 rooms)²

= 900 rooms²

Therefore, the point estimate of the population variance is 900 (rooms squared).

b. To calculate the 90% confidence interval estimate of the population variance, we need to use the Chi-Square distribution.

The formula for the confidence interval of the population variance is:

Lower bound: (n-1)*sample variance / Chi-Square upper critical value

Upper bound: (n-1)*sample variance / Chi-Square lower critical value

Since we are interested in a 90% confidence interval, the Chi-Square critical values for the upper and lower tails with (n-1) degrees of freedom are 8.907 and 32.852, respectively.

Plugging in the values, we have:

Lower bound: (20-1)*900 / 32.852

≈ 486

Upper bound: (20-1)*900 / 8.907

≈ 1706

Therefore, the 90% confidence interval estimate of the population variance is approximately (486, 1706) (rooms squared).

c. To calculate the 90% confidence interval estimate of the population standard deviation, we take the square root of the lower and upper bounds of the confidence interval for the variance.

Square root of the lower bound: √486

≈ 22.0

Square root of the upper bound: √1706

≈ 41.3

Therefore, the 90% confidence interval estimate of the population standard deviation is approximately (22.0, 41.3) rooms.

The 99% confidence interval for the population proportion p is (0.776, 0.824).

To find the 99% confidence interval for a proportion, we can use the formula:

CI = p^ ± z*(SE)

where p^ is the sample proportion, SE is the standard error, and z is the critical value from the standard normal distribution corresponding to the level of confidence.

For a 99% confidence interval, the critical value z is 2.576.

Substituting the given values into the formula, we have:

CI = 0.80 ± 2.576*(0.03/√200)

Simplifying this expression, we have:

CI = 0.80 ± 0.024

This means that we are 99% confident that the true population proportion falls between 0.776 and 0.824. We can interpret this interval as a range of plausible values for the population proportion, based on the sample data.

g(x) is the translation 5 units right of f(x)= – 7(x–5)²+3.

A function called f(x) accepts an input of "x" and outputs "y". You can write it out as y = f. (x).‘x’ is a variable that represents an input to a function.

To translate a function, we need to replace x with (x-a) in the function f(x) where ‘a’ is the amount of translation.

To translate a function 5 units right, we need to replace x with (x-5) in the function f(x).

So, g(x) = f(x-5) = -7(x-5-5)²+ 3 = -7(x-10)²+ 3.

Therefore, g(x) is the translation 5 units right of f(x)= – 7(x–5)²+3.

Answer:

37

Step-by-step explanation:

Before we find quartile, we have to arrange the data set in order first from least to greatest which this problem has already arranged the data for us.

Next, proceed with the calculation. The formula for finding position of quartile is:

\(\displaystyle{Q_r = \dfrac{r(N+1)}{4}}\)

Where \(\displaystyle{Q_r}\) means the rth quartile, N means number of data set. Since we want to find the third quartile, substitute r = 3 and there are 11 data so substitute N = 11:

\(\displaystyle{Q_3 = \dfrac{3(11+1)}{4}}\\\\\displaystyle{Q_3 = \dfrac{3(12)}{4}}\\\\\displaystyle{Q_3 = 3\cdot 3}\\\\\displaystyle{Q_3 = 9}\)

So the position of third quartile is at 9th position which is 37.

Henceforth, the third quartile is 37.

Answer:

37.

Step-by-step explanation:

The data is in ascending order, which is what we need to get the answer.

As there are 11 numbers the 9th number is the upper(third)  quartile.

The median ( middle) number is 29 and the upper quartile is the middle number of the 5 numbers to the right of the median.
