Answer:

∠ ABC ≈ 137.9°

Step-by-step explanation:

Using the Cosine rule in Δ ABC

cos B = [tex]\frac{a^2+c^2-b^2}{2ac}[/tex]

with a = 89, b = 144, c = 65

cos B = [tex]\frac{89^2+65^2-144^2}{2(89)(65)}[/tex] = [tex]\frac{7921+4225-20736}{11570}[/tex] = [tex]\frac{-8590}{11570}[/tex] , thus

B = [tex]cos^{-1}[/tex] ( - [tex]\frac{8590}{11570}[/tex] ) ≈ 137.9° ( to the nearest tenth )

Answer:

Price decrease = 24 %

Step-by-step explanation:

Given:

Initial price of the 60 inch television = $ 1050

Final price of the same television = $ 798

We have to find by what percent did the price of the television decrease.

Let the percent decrease be "x".

Formula to be used:

⇒ [tex]Percent\ decrease =\frac{(Initial\ price) - (Final\ price)}{Initial\ price}\times 100[/tex]

Using the above formula:

And plugging the values.

⇒ [tex]\%\ decrease =\frac{(Initial\ price) - (Final\ price)}{Initial\ price}\times 100[/tex]

⇒ [tex]\%\ decrease =\frac{(1050) - (798)}{1050}\times 100[/tex]

⇒ [tex]\%\ decrease =\frac{252}{1050}\times 100[/tex]

⇒ [tex]\%\ decrease =0.24\times 100[/tex]

⇒ [tex]\%\ decrease =24[/tex]

By 24 percent did the price of the television decreases.

Answer:

36 km

Step-by-step explanation:

Let time taken by upstream=x hours

Upstream speed=12 km/h

Time spend  for sightseeing=2 hours

Total time=7 hours

Traveling time=7-2=5 hours

Time taken by downstream=5-x

Downstream speed=18km/h

Distance=[tex]speed\times time[/tex]

Using the formula

Distance traveled when Delta Duchess paddled upstream=12 x

Distance traveled when  Delta Duchess paddled back=18(5-x)

According to question

[tex]12x=18(5-x)[/tex]

[tex]12x=90-18x[/tex]

[tex]12x+18x=90[/tex]

[tex]30x=90[/tex]

[tex]x=\frac{90}{30}=3 hours[/tex]

Substitute the values

Distance traveled when Delta Duchess paddled upstream=[tex]12\times 3=36 km[/tex]

Answer:

R(t)=401−10t

Step-by-step explanation:

Given the data, there appears to be a negative linear relationship between time and radius as the balloon deflates. This suggests a model of the form R(t) = a - bt best fits the data.

The subject matter here is a Mathematical topic related to model fitting - a statistical method that estimates the relationship between variables. In this case, the variables are Time (t) and radius (R). From the given data, it seems that the radius is reducing as the time increases, which likely indicates a negative linear relationship.

We can also observe that the data points reduce at a constant rate (e.g., it goes down by 50 cm every 5 seconds initially), which further supports the idea of a linear model.

Therefore, considering this rate of change and the mathematical relationship between the variables, a linear model of the form R(t) = a - bt (where a is the initial radius and b is the rate of decrease) would likely be the best option.

The circumference of Cole's bass drum is 25.12 inches.

The formula to find the circumference (C) of a circle is C = 2πr, where r is the radius and π is approximately 3.14.

Since Cole's bass drum has a radius of 4 inches, we substitute the values into the formula to get

C = 2 × 3.14 × 4 inches.

So, the circumference of Cole's drum is C = 2×3.14 × 4 = 25.12 inches.

Answer:

The area of the larger circle is 9 times greater than that of the smaller circle.

Step-by-step explanation:

Let d be the diameter of the smaller circle and d be the diameter of the larger circle. If d₁ = 3d

Since Area of a circle A = πd²/4 ⇒ A ∝ d²

Let A be the area of the smaller circle and A₁ be the area of the larger circle.

So, A₁/A = d₁²/d² = (3d)²/d² = 9

A₁/A = 9

A₁ = 9A

So the area of the larger circle is 9 times greater than that of the smaller circle.

Answer:

9 times greater

Step-by-step explanation:

Let radius of small circle b r

radius of big circle = 3×(r) = 3r

Area of small circle  = πr²

Area of big circle = π(3r)² = 9πr²

How many times area of big circle is larger = 9πr²/ πr² = 9

Answer:

B = 612.2 ft

Step-by-step explanation:

Solution:-

- The elevation of person, H = 235 ft

- The angle of depression, θ = 21°

- We will sketch a right angle triangle with Height (H), and Base (B) : the boat's distance to the edge of the cliff and the angle (θ) between B and the direct line of sight distance.

- We will use trigonometric ratios to determine the distance between boat and the edge of the cliff, using tangent function.

                             tan ( θ ) = H / B

                             B = H / tan ( θ )

                             B = 235 / tan ( 21 )

                             B = 612.2 ft    

Answer:

The distance of the boat from the edge of the cliff is 655.75 ft

Distance of the boat from the base of the cliff is 251.72 ft

Step-by-step explanation:

Height of person above sea level = 235 ft

Angle of depression of sight to the boat from the person = 21°

Therefore, based on similar angle between person and angle of depression and the boat with angle of elevation we have,

Angle of elevation of the location of the person as sighted from the boat θ = 21°

Distance from the edge of the cliff of the boat is then given by;

[tex]Sin\theta = \frac{Opposite \, side \, to\, angle}{Hypothenus\, side \, of\, triangle} = \frac{Height\, of\, person\, above \, ses \, level}{Distance\, of\, boat\, from \, edge\, of \, cliff}[/tex]

[tex]Sin21 =\frac{235}{Distance\, of\, boat\, from \, edge\, of \, cliff}[/tex]

[tex]Distance\, of\, boat\, from \, edge\, of \, cliff=\frac{235}{Sin21 } = \frac{235}{0.358} = 655.75 \, ft[/tex]

Distance of the boat from the base of the cliff is given by

[tex]Distance\, of\, boat\, from \, base\, of \, cliff=\frac{235}{cos21 } = \frac{235}{0.934} = 251.72 \, ft[/tex].

Step-by-step explanation:

Given

it is a right angled triangle so

with reference angle x

hypotenuse (h) = 12

base (b) = 5

Now

cos x = b / h

cos x = 5 / 12

x = cos ^-1 ( 5/12)

Therefore x = 65.4°

Radius = 5inch

CD = 2.75 cm

Step-by-step explanation:

A) isosceles triangles AC = AD  BC = BD  BC = AC you join lines up and then do Pythagoras.  AC ² =  1/2 * 8 ²  +  1/2 6²

AC² = 4sq + 3sq

25sq = 16sq + 9sq

AC² = 25sq = 5inch

Radius = 5inch

B) AB = 8inch  CD = 6inch  radius = 5  ratio = 4 : 3 : 2.5

AB = 24cm CD =  18  radius = 13cm  ratio = 4 : 3 : 2.1

4- 2.1 = 1.9   1.9 distributed = 1.30 + 0.65 + 1 =2.75

so ratio must be 4: 2.75 : 2.1 = 4 : 3 : 2.5

Therefore CD = 2.75 cm

Answer:

The population of city Y is 20 times than that of city X.

Step-by-step explanation:

Given:

City X has a population of 3 times 10^5

City Y has a population of 6 times 10^6.

Question asked:

Which statement correctly describes the relationship between the population of city X and city Y?

Solution:

If we will be able to find the number of times the population of city Y more than that of city X, it will be the best and easy to understand relationship between the population of these two towns:

And we can easily calculate by dividing the population of city Y by population of city X.

[tex]=\frac{6\times10^{6} }{3\times10^{5}} \\ \\ =\frac{6\times10^{6-5} }{3}\ (\frac{a^{m} }{a^{n} }= a^{m-n} )[/tex]

[tex]=\frac{6\times10^{1} }{3} \\ \\ =\frac{60}{3} \\ \\ =20\ times[/tex]

Thus, the population of city Y is 20 times than that of city X.

City Y's population is 20 times larger than that of city X. This is determined by dividing City Y's population by City X's.

The relationship between the populations of city X and city Y can be understood by comparing the numbers provided: 3 times 10^5 (or 300,000) for city X and 6 times 10^6 (or 6,000,000) for city Y. It's clear that city Y has a significantly larger population. In fact, city Y's population is 20 times larger than that of city X.

This is calculated by dividing city Y's population (6,000,000) by city X's population (300,000), getting the result 20.

Down payment on the Car=$2800

Number of Monthly Installments=36

Amount Paid Per Installment=$612

Total Monthly Installment Paid=36*$612=$22032

Therefore, the Total Amount Paid for the Car=Down Payment+Total Installmental Payment=2800+22032=$24,832

Next, we determine the finance charge.

Finance Charge=Total Amount Paid for the Car - Delivered Price of the Car

=24832-22450

=$2,382

Therefore:

Total amount paid for the Car=$24,832

The set 2 contains an outlier.

The range measure of spread was most impacted by the outlier.

A box and whisker plot displays a "box" with its left edge at Q₁, right edge at Q₃, "center" at Q₂ (the median), and "whiskers" at the maximum and minimum.

Given:

Set 1: 8, 15, 13, 7, 11, 17, 13

Median = 13

Lower quartile = 8

Upper quartile = 15

Range = 10

Interquartile range = 7

And Set 2: 8, 15, 13, 7, 11, 17, 13, 100

Median = 13

Lower quartile = 9.5

Upper quartile = 16

Range = 93

Interquartile range = 6.5

Set two contains the value 100 as an outlier.

The range is the component of spread that was most adversely affected by the outlier.

This is due to the fact that set two's median, quartiles, and interquartile range are all closely clustered together, but the range is 93, which is extremely disproportional high compared to any of those other numbers.

Therefore, set 2 contains an outlier.

Answer:

0.1835

Step-by-step explanation:

This question can be solved by way of binomial distribution.

Let’s have the probability of success as p which is the probability that they stay with the company for more than five years;

p = 8/100 = 0.08

probability of failure, meaning not staying is q = 1-p = 1-0.08 = 0.92

Now let’s write the expression for the binomial distribution. That would be;

probability = 12C2 * 0.08^2 * 0.92^10

= 0.1835

Probabilities are used to determine the chances of an event.

The probability that exactly two stays more than 5 years is 0.1835

The given parameters are:

[tex]\mathbf{n = 12}[/tex] ---- sample

[tex]\mathbf{x = 2}[/tex] --- selected

[tex]\mathbf{p = 80\%}[/tex] --- sample proportion

So, the probability that exactly two stays more than 5 years is calculated using the following binomial probability:

[tex]\mathbf{P(x) = ^nC_x p^x (1 - p)^{n -x}}[/tex]

So, we have:

[tex]\mathbf{P(x) = ^{12}C_2 (8\%)^2 (1 - 8\%)^{12 -2}}[/tex]

[tex]\mathbf{P(x) = ^{12}C_2 (8\%)^2 (92\%)^{10}}[/tex]

Solve 12C2 using a calculator

[tex]\mathbf{P(x = 2) = 66 \times (8\%)^2 \times (92\%)^{10}}[/tex]

[tex]\mathbf{P(x = 2) = 0.1835}[/tex]

Hence, the probability that exactly two stays more than 5 years is 0.1835
