Answer:

X = 5

Step-by-step explanation:

To solve for x, you need to get x to one side and everything else to the other side.

3x+20=x+30

Since there is only one positive x on the right, we can subtract it from both sides. This moves it over.

2x+20=30

Since there is a +20 on the same side we put our x, we need to subtract it from both sides to move it over.

2x = 10

Now x is being multiplied by 2. To get rid of it, we divide both sides by 2.

x = 5

The best estimate, based on this simulation, of the probability that in his next 5 backflips Daniel will land more than 3 of them is 27%.

Given

Daniel is able to land his backflip 60% of the time.

He tells his friend that in his next 5 backflips, he will land more than 3 of them.

Daniel uses a computer to randomly select 5 numbers from 1 through 5. He lets 1 through 3 represent landing his backflip and 4 and 5 represent not landing it.

He repeats this for a total of 22 trials and records the results in the table below.

43113 43323 21245 53154 11545 44511 45221 14221 11123 55131 24535

Probability is defined as the number of trials in which he landed more than three times/Total number of trials.

Let, p denotes the probability of an event.

The best estimate, based on this simulation, of the probability, that in his next 5 backflips Daniel will land more than 3 of them is;

[tex]\rm Probability=\dfrac{6}{22} \times 100\\\\Probability =\dfrac{600}{22}\\\\Probability=27[/tex]

Hence, the best estimate, based on this simulation, of the probability that in his next 5 backflips Daniel will land more than 3 of them is 27%.

Answer:

3/2

Step-by-step explanation:

sin(3π/4 - β) = sin(3π/4)cosβ - cos(3π/4)sinπ =

[tex]\sin(\frac{3\pi}{4}-\beta)=\sin(\frac{3\pi}{4})\cos\beta-\cos\frac{3\pi}{4}\sin\beta\\=\frac{1}{\sqrt{2}}\cos\beta-(-\frac{1}{\sqrt{2}})\sin\beta\\\\=\frac{1}{\sqrt{2}}(\cos\beta +\sin\beta)\\\\\sin^2(\frac{3\pi}{4}-\beta)=\frac{1}{2}\cos\beta +\sin\beta)^2=\frac{1}{2}(\cos^2\beta +\sin^2\beta+2\sin\beta\cos\beta\\=\frac{1}{2}(1+\sin2\beta)=\frac{1}{2}(1-\frac{1}{5}) = \frac{2}{5}\\[/tex]

Use [tex]\cot^2x=\csc^2x-1=\frac{1}{\sin^2x}-1[/tex]

so

[tex]\cot^2(\frac{3\pi}{4}-\beta)=\frac{1}{\sin^2(\frac{3\pi}{4}-\beta)}-1 = \frac{1}{\frac{2}{5}}-1=\frac{5}{2}-1=\frac{3}{2}[/tex]

Answer:

Step-by-step explanation:

In similar polygons, corresponding sides are in same proportion

[tex]\dfrac{GK}{VR}=\dfrac{KN}{RP}\\\\\\\dfrac{14.7}{6.3}=\dfrac{x+1}{4x-3}\\\\\dfrac{0.7*10}0.3*10}=\dfrac{x+1}{4x-3}\\\\\dfrac{7}{3}=\dfrac{x+1}{4x-3}[/tex]

Cross multiply

7*(4x-3)=3*(x+1)

28x - 21 = 3x + 3

28x - 3x - 21 = 3

25x = 3 + 21

25x = 24

x = 24/25

x = 0.96

Answer:

A) 0 ≤ n ≤ 7

B) initial height of plant = 8 cm

C) average rate of change = 0.475 cm/day.  

Plant grew an average of 0.475 cm per day from day 2 to day 6

Step-by-step explanation:

[tex]f(n)=8(1.05)^n[/tex]

Part A

Given height = 11.26 cm

[tex]\implies 8(1.05)^n=11.26[/tex]

[tex]\implies(1.05)^n=\dfrac{11.26}{8}[/tex]

[tex]\implies(1.05)^n=1.4075[/tex]

Taking natural logs:

[tex]\implies \ln(1.05)^n=\ln(1.4075)[/tex]

[tex]\implies n\ln(1.05)=\ln(1.4075)[/tex]

[tex]\implies n=\dfrac{\ln(1.4075)}{\ln(1.05)}[/tex]

[tex]\implies n=7.005819448[/tex]

[tex]\implies n \approx7[/tex]

Therefore, the scientist concluded his study after 7 days, so the domain is 0 ≤ n ≤ 7

Part B

y-intercept is when the curve intersects the y-axis (when n = 0):

[tex]\implies f(0)=8(1.05)&^0=8\times1=8[/tex]

The y-intercept represents the initial height of the plant, which is 8 cm

Part C

Rate of change = change in y ÷ change in x

⇒ rate of change = change in f(n) ÷ change in n

[tex]\implies f(2)=8(1.05)^2=8.82[/tex]

[tex]\implies f(6)=8(1.05)^6=10.72076513...[/tex]

[tex]\implies \textsf{rate of change} \ =\dfrac{f(6)-f(2)}{6-2}=0.4751912813...[/tex]

So the average rate of change was 0.475 cm/day.  This indicates that the plant grew an average of 0.475 cm per day from day 2 to day 6 (over a period of 4 days).

ETA: please see attached graph.  The gray dotted curve is the function, and the black solid curve is the function with the restricted domain of 0≤n≤7 since the study took 7 days.

Answer:

y= 8000x + 2000

Step-by-step explanation:

to find the formula we can use the points given in the question:

the slope:

to get the slope we can take the 2 points, (0,2000) and (2,18000) where x values are time and y values are bacteria

now using slope-intercept form we can get [tex]\frac{18000-2000}{2-0}[/tex] which gives a slope of 8000 meaning for each hour there are 8000 new bacteria

intercept:

since we start with 2000 bacteria we know this is the y intercept so when x is 0

formula:

y=8000x + 2000

The capacity of this fuel can is equal to 5 liters.

Given the following data:

To calculate the capacity of this fuel can in litres:

In order to calculate the capacity of this fuel can, we would determine its volume by using this formula:

[tex]Volume = length \times breadth \times height[/tex]

Substituting the given parameters into the formula, we have;

[tex]Volume = 10 \times 20 \times 25[/tex]

Volume = 5,000 [tex]cm^3[/tex].

In liters:

1 [tex]cm^3[/tex] = 0.001 liters.

5000 [tex]cm^3[/tex] = 5 liters.

Capacity = 5 liters.
