\(\sqrt{x} 4=x-3\)

Answer:

wouldn't it be A?

Step-by-step explanation:

The probability that x is greater than 77. 5 is 0.039828

Given,

Mean, μ = 80

Standard deviation, σ = 25

We have to find z score corresponding to 77.5

z = (x-μ) / σ

   \(=\frac{77.5-80}{25} \\= 0.1\)

Now we have to find P value from Z table:

P(x<77.5) = 0.46017

P(x>77.5) = 1 - P(x<77.5) = 0.53983

P(77.5<x<80) = 0.5 - P(x<77.5) = 0.039828

The probability of x greater than 77.5 is 0.039828

The Blu-ray movie will cost approximately $36.42 in 5 years with an inflation rate of 12% and continuous compounding.

To calculate the future cost of the Blu-ray movie in 5 years with an inflation rate of 12% and continuous compounding, we can use the formula for continuous compound interest:

A = P * e^(rt)

Where:

A = Future value

P = Present value

e = Euler's number (approximately 2.71828)

r = Annual interest rate (in decimal form)

t = Time period in years

In this case, the present value (P) is $19.99, the inflation rate (r) is 12% or 0.12, and the time period (t) is 5 years. Substituting these values into the formula, we get:

A = 19.99 * e^(0.12 * 5)

Calculating the exponent first:

0.12 * 5 = 0.6

Then:

e^0.6 ≈ 1.82212

Finally:

A = 19.99 * 1.82212 ≈ 36.42

Using the formula for continuous compound interest, we calculated that a Blu-ray movie that costs $19.99 today will cost approximately $36.42 in 5 years, assuming an inflation rate of 12% and continuous compounding.

In order to increase the likelihood that a blue marble would be drawn at random to 3/4, we must thus add 32 more blue marbles.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to express probabilities.

Here,

Let the number of blue marbles added be x,

Probability=3/4

Total marbles=20

Number of blue marbles=7

(7+x)/(20+x)=3/4

4(7+x)=3(20+x)

28+4x=60+3x

x=60-28

x=32

So, we need to add 32 more blue marbles to make the probability of randomly drawing a blue marble be 3/4.

The exponential regression equation will be given as;

y = A₀e^(kx)

Where;

A₀ is the coefficient of exponential regression.

k is the constant.

For x = 0, the value of y will be $ 14100. Then we have;

18200 = A₀e^(k * 0)

Thus; A₀ = 18200

Thus, the exponential regression equation is;

y = 18200e^(kx)

For x = 1, the value of y will be $15728. Then we have;

15728 = 18200e^(k * 1)

Thus; k = -0.146

The equation is now;

y = 18200e^(-0.146x)

The potential between points P and Q are 105 units.

To find the potential between two points, we need to integrate the electric field along the path connecting the points. The electric field is given by E = 40xyi + 20x^2j + 2k.

Let's denote the position vector of point P as r_p = xi + yj + zk, and the position vector of point Q as r_q = xi + yj + zk.

The potential difference ΔV between P and Q is given by:

ΔV = ∫ E · dr,

where dr is an infinitesimal displacement along the path connecting P and Q.

In this case, the path is a straight line from P to Q, so we can parametrize it as r = r_p + t(r_q - r_p), where t varies from 0 to 1.

Substituting the electric field E into the integral, we have:

ΔV = ∫ (40xyi + 20x^2j + 2k) · (dx/dt)i + (dy/dt)j + (dz/dt)k,

where dx/dt, dy/dt, and dz/dt are the derivatives of x, y, and z with respect to t.

Simplifying the dot product and integrating term by term, we get:

ΔV = ∫ (40xydx/dt + 20x^2dy/dt + 2*dz/dt) dt.

Now, let's calculate the derivatives dx/dt, dy/dt, and dz/dt:

dx/dt = d(xi)/dt = 0, since x does not vary with t.

dy/dt = d(yj)/dt = 0, since y does not vary with t.

dz/dt = d(zk)/dt = 0, since z does not vary with t.

Therefore, the integrals for dy/dt and dz/dt will be zero.

The integral for dx/dt is:

∫ (40xy*dx/dt) dt = 40xy ∫ (dx/dt) dt

= 40xy ∫ 0 dt

= 0.

So, the potential difference ΔV reduces to:

ΔV = ∫ (40xydx/dt + 20x^2dy/dt + 2*dz/dt) dt

= ∫ (0 + 0 + 0) dt

= 0.

Hence, the potential difference between points P and Q is zero. Therefore, the answer options provided (a) 104, (b) 105, (c) 106, (d) 107 are all incorrect.

To get from ADEF to AD'E'F', we need to perform a series of transformations (translations, rotations, reflections, or combinations of these). The options that are possible ways to get from ADEF to AD'E'F' are:

A. Reflect DEF across the y-axis, then translate 12 units to the right and 1 unit down.

B. Reflect DEF across the x-axis, then translate 12 units to the right and 1 unit up.

C. Rotate DEF 180 degrees counterclockwise about the point (−3, 2), then translate 11 units to the right and 1 unit up.

D. Translate DEF 12 units to the right and 1 unit up.

Option C is NOT a way to get from ADEF to AD'E'F' because rotating DEF 180 degrees counterclockwise about the point (−3, 2) would result in a triangle with vertices D (-5, 1), E (-2, 0), and F (-6, -1).

X is normally distributed with mean 5 and standard deviation 0.4.  The value of Xo is 5.52.

To find the value of Xo, we need to convert the given probability to a z-score using the standard normal distribution.

The z-score formula is given by:

z = (X - μ) / σ

Where:

X is the observed value

μ is the mean of the distribution

σ is the standard deviation of the distribution

In this case, the mean (μ) is 5 and the standard deviation (σ) is 0.4. We are given that P(X ≤ Xo) is equivalent to P(Z ≤ 1.3), which means we need to find the value of Xo that corresponds to a z-score of 1.3.

To find the value of Xo, we rearrange the formula:

Xo = z * σ + μ

Plugging in the values, we have:

Xo = 1.3 * 0.4 + 5

Xo = 0.52 + 5

Xo = 5.52

Therefore, the value of Xo is 5.52.

Similarly, in Indian cuisine, the use of spices and herbs is an integral part of the cooking process, and the proper combination of these ingredients is critical to the taste of the dish.

In today's society, advertising is a form of influence on food habits. Companies spend millions of dollars each year on advertising their products, and these ads can have a significant impact on what people choose to eat. For example, fast food companies often use advertising to promote their products as convenient and affordable options for busy people.

This can lead to people choosing these types of foods over healthier options, which can have negative health consequences in the long run. It's important to be aware of the influence of advertising on our food choices and to make informed decisions about what we eat.

The probability that Luke will hit the inner ring fewer than 3 times is  0.069.

To calculate the probability that the number of times Luke will hit the inner ring of the target out of the 5 attempts is less than the mean of X, we need to know the distribution of X.

Assuming that each shot is independent and has the same probability p of hitting the inner ring, X follows a binomial distribution with parameters n=5 and p.

The mean of a binomial distribution is given by μ = np, so in this case, the mean of X is 5p.

To find the probability that X is less than 5p, we can use the cumulative distribution function (CDF) of the binomial distribution. Let F(k) denote the CDF of the binomial distribution with parameters n=5 and p, evaluated at k.

Then the probability that X is less than 5p is:

P(X < 5p) = F(4p)

Note that we use 4p instead of 5p in the argument of F, since we want the probability that X is strictly less than 5p, not less than or equal to 5p.

Using a binomial table or calculator, we can look up or compute the value of F(4p) for a given value of p.

For example, if p=0.6 (which corresponds to Luke hitting the inner ring 60% of the time), we get:

P(X < 5p) = F(2.4) ≈ 0.069

So the probability that Luke will hit the inner ring fewer than 3 times (which is less than 5p=3) out of the 5 attempts is about 0.069, assuming he hits the inner ring with a probability of 0.6 on each shot.

He will be able to buy the refrigerator with the amount he deposited ($500) plus the interest generated from it ($35)(which we get by doing the following):

So the formula for interest is

Interest = (principal ×interest rate × time for which the money was deposited) / 100

Interest = ?

Principal = $500

Interest rate = 7%

Time = 1 year

Now

Interest = (500 × 7 × 1) / 100

Interest = 3500/ 100

Interest = $35

So the refrigerater's cost = 500 + 35

Cost = $ 535
