Answer 1

Answer: C

Step-by-step explanation:

If you look at the equation, you can see that you can cancel out a 9z³ on both sides. 9z³ is what both fractions have in common. This leaves us with 1 on the numerator on the first fraction and 2 for the denominator on the second fraction.

[tex]\frac{1}{16xy} *\frac{4x}{3}[/tex]

You can also cancel out 4x since both fractions have a 4x in common. This leaves the denominator of the first equation with 4y and the numerator of the second equation with 1.

[tex]\frac{1}{4y} *\frac{1}{3}[/tex]

Now, we can multiply straight across.

[tex]\frac{1}{12y}[/tex]

Find an explicit formula for f(n)f(n)f, left parenthesis, n, right parenthesis

Answers

Answer:

f(n)=-5-3n

Step-by-step explanation:

Given the recursive formula of a sequence

f(1)=−8

f(n)=f(n−1)−3

We are to determine an explicit formula for the sequence.

f(2)=f(2-1)-3

=f(1)-3

=-8-3

f(2)=-11

f(3)=f(3-1)-3

=f(2)-3

=-11-3

f(3)=-14

We write the first few terms of the sequence.

-8, -11, -14, ...

This is an arithmetic sequence where the:

First term, a= -8

Common difference, d=-11-(-8)=-11+8

d=-3

The nth term of an arithmetic sequence is determined using the formula:

T(n)=a+(n-1)d

Substituting the derived values, we have:

T(n)=-8-3(n-1)

=-8-3n+3

T(n)=-5-3n

Therefore, the explicit formula for f(n) can be written as:

f(n)=-5-3n

Each have four possible answers left parenthesis a,b,c,d right parenthesis​, one of which is correct. Assume that you guess the answers to three such questions.
a. Use the multiplication rule to find ​P(CWC​), where C denotes a correct answer and W denotes a wrong answer.
b. Beginning with CWC​, make a complete list of the different possible arrangements of two correct answers and one wrong answer​, then find the probability for each entry in the list.​P(CWC​)minussee above ​P(WCC​)equals? 0.046875 ​P(CCW​)equals? 0.046875 ​(Type exact​ answers.)
c. Based on the preceding​ results, what is the probability of getting exactly two correct answers when three guesses are​made?

Answers

Answer:

a. P(CWC)=0.046875

b.  P(WCC)=0.046875

    P(CCW)=0.046875

c. P=0.140625

Step-by-step explanation:

By the rule of multiplication there are 64 forms to answer three questions. This is calculated as:

    4 _          *            4               *             4            = 64

1st question      2nd question     3rd question

Because there are 4 options for every question. At the same way, from that 64 options, 3 are CWC and it is calculated as:

    1 _          *            3               *             1            = 3

1st question      2nd question     3rd question

Because there is just one answer that is correct for the first question, there are 3 answers wrong for the second question and there are 1 answer correct for the third question.

So, the probability P(CWC) is equal to:

[tex]P(CWC)=\frac{3}{64}=0.046875[/tex]

Then, the complete list of the different possible arrangements of two correct answers and one wrong answer are: CWC, WCC and CCW

Therefore, the probabilities P(WCC) and P(CCW) are calculated as:

[tex]P(WCC)=\frac{3*1*1}{64}=\frac{3}{4}= 0.046875[/tex]

[tex]P(CCW)=\frac{1*1*3}{64}=\frac{3}{4}= 0.046875[/tex]

Finally, the probability of getting exactly two correct answers is the sum of the probabilities calculated before.

[tex]P=P(CWC)+P(WCC)+P(CCW)\\P=0.046875+0.046875+0.046875\\P=0.140625[/tex]

The iron cube of side 42 com has a hole of diameter 14cm
drilled out. Calculate the volume of iron in the cube
and the total Surface area
of the Cube​

Answers

Answer:

Step-by-step explanation:

Total surface of the cube = 6a²

                                          = 6 * 42 * 42

                                          = 10584 cm²

Hole that is drilled out, will make a cylinder shape in the middle of the cube

Volume  of iron in the cube = Volume of cube  - volume of cylinder

Volume of cube = a³

                          = 42 * 42 * 42

                         = 74088 cm³

Cylinder:

r = 14/2 = 7 cm

h = sideof the cube = 42 cm

Volume = πr²h

            [tex]=\frac{22}{7}*7*7*42\\\\=22*7*7*6[/tex]

           = 6468 cm³

Volume  of iron in the cube = Volume of cube  - volume of cylinder

                                             = 74088 - 6468

                                             = 67620 cm³

Which of the following graphs represents the equation y=3x+2?

Answers

Answer:graph C is the answer because if you put the both values from the graph it satisfies the equation

Answer:

Graph C

Step-by-step explanation:

The given equation is in the form y=mx+b

This is slope-intercept form.

This is where m represents the slope, and b represents the y-intercept.

Therefore, the slope is 3 and the y-intercept is 2.

Let's first name all the equations with a y-intercept of 2.

That would be B and C.

Now, let's find the equation with a slope of 3.

Let's find the slope for B.

The formula for slope is: y1-y2/x1-x2

A point is: (x coordinate, y coordinate)

In the formula,

y1 is the y coordinate of the first point

y2 is the y coordinate of the second point

x1 is the x coordinate of the first point

x2 is the x coordinate of the second point

This said, we can plug our points in.

6-2/2-0

4/2

2

The slope for Graph B is 2, so it is incorrect.

Let's find the slope for Graph C.

2-(-1)/0-(-1)

2+1/0+1

3/1

3

The slope for Graph C  is 3, and it has a y-intercept of 2, so Graph C is the correct choice.

For a super soaker water gun, a pump handle is moved back and forth to build up pressure in the water reservoir. The water is released by pulling a trigger and shooting the water a significant distance. Assuming that you can create an absolute pressure of 8 atm in the reservoir:
a) What is the velocity at which the water leaves the gun?
b) If the water exits the gun through a hole with a radius of 1-mm, what is the volume rate of flow in m3/s?
c) If the water gun is fired horizontally and held 1.2 meters above the ground, where does the water hit the ground? Pressure 8 cm water

Answers

Answer:

a) The velocity at which the water leaves the gun = 37.66 m/s

b) The volume rate of flow = (1.183 × 10⁻⁴) m³/s

c) The water hits the ground 18.64 m from the point where the water gun was shot.

Step-by-step explanation:

a) Using Bernoulli's equation, an equation that is based on the conservation of energy.

P₁ + ½ρv₁² + ρgh₁ = P₂ + ½ρv₂² + ρgh₂

The two levels we are considering is just inside the water reservoir and just outside it.

ρgh is an extension of potential energy and since the two levels are at the same height,

ρgh₁ = ρgh₂

Bernoulli's equation becomes

P₁ + ½ρv₁² = P₂ + ½ρv₂²

P₁ = Pressure inside the water reservoir = 8 atm = 8 × 101325 = 810,600 Pa

ρ = density of water = 1000 kg/m³

v₁ = velocity iof f water in the reservoir = 0 m/s

P₂ = Pressure outside the water reservoir = atmospheric pressure = 1 atm = 1 × 101325 = 101,325 Pa

v₂ = velocity outside the reservoir = ?

810,600 + 0 = 101,325 + 0.5×1000×v₂²

500v₂² = 810,600 - 101,325 = 709,275

v₂² = (709,275/500) = 1,418.55

v₂ = √(1418.55) = 37.66 m/s

b) Volumetric flowrate is given as

Q = Av

A = Cross sectional Area of the channel of flow = πr² = π×(0.001)² = 0.0000031416 m²

v = velocity = 37.66 m/s

Q = 0.0000031416 × 37.66 = 0.0001183123 m³/s = (1.183 × 10⁻⁴) m³/s

c) If the height of gun above the ground is 1.2 m. Where does the water hit the ground?

The range of trajectory motion is given as

R = vT

v = horizontal component of the velocity = 37.66 m/s

T = time of flight = ?

But time of flight is given as

T = √(2H/g) (Since the initial vertical component of the velocity = 0 m/s

H = 1.2 m

g = acceleration due to gravity = 9.8 m/s²

T = √(2×1.2/9.8) = 0.495 s

Range = vT = 37.66 × 0.495 = 18.64 m

Question:

The geometric sequence ; is defined by the formula: [tex]a_1 =10[/tex] ; [tex]a_i =a_{i-1} * \frac{9}{10}[/tex] Find the sum of the first 75 terms in the sequence .

Answer:

[tex]S_{75} = 99.963001151[/tex]

Step-by-step explanation:

Given

[tex]a_1 =10[/tex]

[tex]a_i =a_{i-1} * \frac{9}{10}[/tex]

Required

Find the sum of 75 terms

Given that the sequence is geometric;

First, the common ratio has to be calculated;

The common ratio is defined as follows;

[tex]r = \frac{a_{i}}{a_{i-1}}[/tex]

Let [tex]i = 2[/tex]

[tex]r = \frac{a_{2}}{a_{2-1}}[/tex]

[tex]r = \frac{a_{2}}{a_{1}}[/tex]

So,

[tex]a_i =a_{i-1} * \frac{9}{10}[/tex] becomes

[tex]a_2 =a_{2-1} * \frac{9}{10}[/tex]

[tex]a_2 =a_{1} * \frac{9}{10}[/tex]

Divide through by [tex]a_1[/tex]

[tex]\frac{a_2}{a_1} =\frac{a_{1} * \frac{9}{10}}{a_1}[/tex]

[tex]\frac{a_2}{a_1} = \frac{9}{10}[/tex]

Recall that [tex]r = \frac{a_{2}}{a_{1}}[/tex]

So, [tex]r = \frac{9}{10}[/tex]

Given that r < 1;

The sum of n terms is calculated as thus;

[tex]S_n = \frac{a(1-r^n)}{1-r}[/tex]

To calculate the sum of the first 75 terms, we have the following parameters

[tex]n = 75\\a = a_1 = 10\\r = \frac{9}{10} = 0.9[/tex]

[tex]S_n = \frac{a(1-r^n)}{1-r}[/tex] becomes

[tex]S_{75} = \frac{10(1-0.9^{75})}{1-0.9}[/tex]

[tex]S_{75} = \frac{10(1-0.9^{75})}{0.1}[/tex]

[tex]S_{75} = 100(1-0.9^{75})[/tex]

[tex]S_{75} = 100(1-0.00036998848)[/tex]

[tex]S_{75} = 100(0.99963001151)[/tex]

[tex]S_{75} = 99.963001151[/tex]

Decode the addition or subtraction problem (Change asterisks to digits, to make the operation correct.) 6*5* − *8*4=2856

Answers

Answer:

  6750 - 3894 = 2856

Step-by-step explanation:

You have to make use of the arithmetic facts you know.

The least-significant asterisk must be 0, because the sum of 4 and 6 is 10.

The 10s asterisk must be 9,so that the sum 5 + 9 + 1 has a least-significant digit of 5.

The 100s asterisk must be 7, because that is the least-significant digit of the sum 8 + 8 + 1 = 17.

The 1000s asterisk must be 3, so that 2 + 3 + 1 = 6.

(The "1" in each of these sums is the carry from the sum of the digits with the next lower place value.)

So, the subtraction problem is ...

  6750 - 3894 = 2856

_____

Comment on the solution method

For the most part, we worked this as an addition problem. The sum of the last two numbers must be equal to the first: 6570 = 3894 +2856. For some of us, addition facts are easier to work with than subtraction facts. The carry/borrow can be less confusing that way.

Suppose Blue Cab Company charges $2.85 a ride up to 0.1 miles and $0.30 for each additional tenth of a mile. If the mean distance a passenger wants to go is 5.3 miles with a standard deviation of 1.4 miles, what is the standard deviation of the fare passengers pay

Answers

Answer:

Provide an appropriate response. A 28-year-old man pays $94 for a one-year life insurance policy with coverage of $120,000. If the probability that he will live through the year is 0.9991, what is the expected value for the insurance policy

Answers

Answer:

$ 14.08

Step-by-step explanation:

We have that the policy costs $ 94 and with life insurance with coverage of $ 120,000, to calculate the expected value, we must subtract the value of that life insurance multiplied with the probability of dying (complement of the probability of living) and the policy value multiplied by the probability of staying alive) like this:

120000 * (1 - 0.9991) - 94 * 0.9991 = 14.0846

Which means that the expected value of the policy is $ 14.08

T(x)=70(.80)*+20 where x is the time in minutes and the T is the temperature in degree celsius . What is the initial temperature of the coffee?

Answers

Answer:

The initial temperature of the coffee was 90°C.

Step-by-step explanation:

The function representing the temperature of the coffee after x minutes is:

[tex]T(x)=70\cdot(0.80)^{x}+20[/tex]

T is the temperature in degree Celsius.

The initial temperature of the coffee will be at x = 0.

Compute the value of T (x) at x = 0 as follows:

[tex]T(x)=70\cdot(0.80)^{x}+20[/tex]

[tex]T(0)=70\cdot (0.80)^{0}+20[/tex]

        [tex]=70\times 1+20\\=70+20\\=90[/tex]

Thus, the initial temperature of the coffee was 90°C.

In general, the probability that a blood donor has Type A blood is 0.40.Consider 8 randomly chosen blood donors, what is the probability that more than half of them have Type A blood?

Answers

The probability that more than half of the 8 randomly chosen blood donors have Type A blood is approximately 0.2533 or 25.33%.

To calculate the probability that more than half of the 8 randomly chosen blood donors have Type A blood, we can use the binomial probability formula:

[tex]\mathrm{P(X > n/2) = \sum [ P(X = k) ]}[/tex]

where the sum is taken from k = (n/2 + 1) to k = n

In this case, n represents the number of trials (8 blood donors) and p is the probability that a single blood donor has Type A blood (0.40).

P(X = k) is the probability of getting exactly k donors with Type A blood, and it is given by the binomial probability formula:

[tex]\mathrm {P(X = k) = (n, k) \times p^k \times (1 - p)^{(n - k)}}[/tex]

where (n choose k) represents the number of combinations of n items taken k at a time, and it is given by:

[tex]\mathrm {(n, k) = \frac{n!}{(k! \times (n - k)!)}}[/tex]

Now, let's calculate the probability that more than half (i.e., 5 or more) of the donors have Type A blood:

[tex]\mathrm{P(X > 4) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8)}[/tex]

2.In a large university 13.5% of the students take economics, 24.7% of the students take statistics and 11.7% take economics and statistics. The probability that a randomly selected student didn’t take economics but did take statistics is close toالقارئ الشامل (2/2 نقط

Answers

Answer:

The probability that a randomly selected student didn’t take economics but did take statistics is 13%.

Step-by-step explanation:

Let the event that a student offers Economics be E.

The event that a student does NOT offer Economics is E'.

Let the event that a student offers Statistics be S.

The event that a student does NOT offer Statistics be S'.

P(E) = 13.5% = 0.135

P(S) = 24.7% = 0.247

P(E n S) = 11.7% = 0.117

Find the probability that a randomly selected student didn’t take economics but did take statistics

This probability = P(E' n S)

Since E and E' are mutually exclusive events,

P(S) = P(E' n S) + P(E n S)

P(E' n S) = P(S) - P(E n S)

P(E' n S) = 0.247 - 0.117 = 0.13 = 13%
