±√121 what is the answer

The correct answer is e, #PRTY, #EYECNT, and MLTSRV in the multiple regression analysis are significant because their coefficients have t-stats greater than the critical value of 2.0 and based on the significant coefficients in the multiple regression, it can be inferred that being customer-friendly with attentive service is a good idea in this context.

The correct answer is e. Based on the given information, #PRTY, #EYECNT, and MLTSRV in the multiple regression are significant because their coefficients have t-stats greater than the critical value of 2.0. It is not strange for #EYECNT to drop from .43 to .25 in the multiple regression as it may be correlated with other independent variables. It is also not unusual for MFPAY to be insignificant in a multiple regression setting and significant in the bivariate setting due to potential confounding variables. Finally, based on the significant coefficients in the multiple regression, it can be inferred that being customer-friendly with attentive service is a good idea in this context.
Your answer: e. a, c, and d
a. #PRTY, #EYECNT, MLTSRV in the multiple regression are significant - This is true because their t-statistics are greater than 1.96 (critical value at 95% confidence level).
b. It is strange the #EYECNT has dropped from .43 to .25 - This is not necessarily strange, as it can happen when other independent variables are included in the multiple regression analysis, which may lead to changes in coefficients due to correlations between variables.
c. It is not strange that MFPAY can be insignificant in a multiple regression setting and significant in the bivariate setting - This is true because the significance of a variable can change when other variables are added to the model, affecting the relationships between them.
d. You can confidently say that the idea to be customer-friendly by attentive service is a good one in this context - This statement can be considered true as #EYECNT, which represents attentive service, is significant in both the bivariate and multiple regression analyses.

Answer: true

Step-by-step explanation: The answer is true. As a linear pair is a pair of adjacent, supplementary angles. Adjacent means next to each other, and supplementary means that the measures of the two angles add up to equal 180 degrees.

Answer:

true

Step-by-step explanation:

The probabilities P(x<40), P(x>21) and P(30< x < 35)

a) P(x < 40) ≈ 0.9938,

b) P(x > 21) ≈ 0.9878,

c) P(30 < x < 35) ≈ 0.3944

Given that, X is a normally distributed variable with mean μ=30 and standard deviation σ=4. We need to find the probabilities P(x<40), P(x>21) and P(30< x < 35)

a) P(x<40)

We need to find

P(x < 40)

P(z) = (x - μ) / σ

z = (40 - 30) / 4

z = 2.5

Now, P(x < 40) = P(z < 2.5)

We can find this probability from the standard normal distribution table:

Using the table,

P(z < 2.5) = 0.9938

So, P(x < 40) ≈ 0.9938

b) P(x>21)

We need to find

P(x > 21)

P(z) = (x - μ) / σ

z = (21 - 30) / 4

z = -2.25

Now, P(x > 21) = P(z > -2.25)

We can find this probability from the standard normal distribution table:

Using the table, P(z > -2.25) = 0.9878

So, P(x > 21) ≈ 0.9878

c) P(30 < x < 35)

We need to find

P(30 < x < 35)

P(z1) = (30 - 30) / 4 = 0

P(z2) = (35 - 30) / 4

= 1.25

Now, P(30 < x < 35) = P(z2) - P(z1)

We can find this probability from the standard normal distribution table:

Using the table,

P(0 < z < 1.25) = 0.3944

So, P(30 < x < 35) ≈ 0.3944

Therefore,

a) P(x < 40) ≈ 0.9938,

b) P(x > 21) ≈ 0.9878,

c) P(30 < x < 35) ≈ 0.3944

Answer: It is 3/2 = p

Step-by-step explanation:

1. 2p - 9 = 3(2p - 5)
2. 2p - 9 = 6p - 15
3. -9 = 4p -15
4. 6 = 4p
5. 3 = 2p
6. 3/2 = p

Answer:

6/4 or 3/2

Step-by-step explanation:

To this problem, we need to use the distributive property, and we also need to combine like terms.

2p-9=3(2p-5)

2p-9=6p-15

Subtract 2p on both sides

-9=4p-15

Add 15 on both sides

6=4p

Now divide 4 on both sides

6/4 or 3/2

The correct set of possible results would be (0, 1, 0, 0), (1, 2, 1, 0) and (1, 2, 0, 1).

Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.

Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).

Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).

Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).

To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.

(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)

Expanding this expression, you get:

(0+a+b, 1+a+b, 0+a, 0+b)

Simplifying, you obtain the following set of solutions:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Therefore, the correct set of possible results would be:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Note that (0, 1, 1, 1) is not a valid solution in this case, as it does not satisfy the initial condition z = 0.

Step-by-step explanation:

if f has domain [0, [infinity]) and has no horizontal asymptotes, then lim x→[infinity] f(x) = [infinity] or lim x→[infinity] f(x) = −[infinity] is true.

If a function f has domain [0, [infinity]) and has no horizontal asymptotes, then as x approaches infinity, f(x) will also approach either infinity or negative infinity. This is because if f does not have a horizontal asymptote, then there is no value y such that f(x) will approach that value as x approaches infinity. Therefore, as x gets larger and larger, f(x) will continue to increase or decrease without any bound.

In conclusion, if f has domain [0, [infinity]) and has no horizontal asymptotes, then lim x→[infinity] f(x) = [infinity] or lim x→[infinity] f(x) = −[infinity] is true.

Sine = Opposite/Hypotenuse

Cosine = Adjacent/ Hypotenuse

Tangent = Opposite/Adjacent

The opposite side is the one that forms the right angle and the other acute angle. Shortest side corresponds to the smallest angle.

The adjacent side is the one that forms the angle mentioned, but not the hypotenuse.

The hypotenuse is the longest side of the triangle; it corresponds to the 90° angle (only right triangles have a hypotenuse)

Answer:

The squirrel runs 11 miles per hour.

Explanation:

Speed can be found from the the slope of the graph of distance over time. From this graph the easiest point to calculate this on is the two endpoints. Slope is rise/run. In this graph Y has increases by 11 miles (rise) at the point where time has increased by one hour (run). So the speed can be found with 11 miles/ 1 hour which equals 11 miles per hour.

The value of the given limit is ∞.

Hence, the correct option is C.

To evaluate the given limit, let's analyze the sum

\(\[ \sum_{i=1}^{n} ln(\frac{n}{n+1})\)

We can simplify the expression inside the logarithm by dividing the numerator and denominator

\(ln(\frac{n+1}{n})=ln(n+1)-ln(n)\)

Now we can rewrite the sum using this simplified expression

\(\[ \sum_{i=1}^{n} (ln(n+1)-ln(n))\)

When we expand the sum, we see that the terms cancel out

\((ln(2)-ln(1))+(ln(3)-ln(2))+(ln(4)-ln(3))+............+(ln(n+1)-ln(n))\)

All the intermediate terms cancel out, leaving only the first and last terms

\(ln(n+1)-ln(1)=ln(n+1)\)

Now we can evaluate the limit as

\(\lim_{n \to \infty} ln(n+1)=ln(\infty)=\infty\)

The probability that at least 25 of the 29 customers have looked at their credit score in the past six months is:

P(X ≥ 25) = sum(P(X = i)) i = 25 to 29

This is a question of probability and statistics, specifically in the area of binomial distributions. The probability of a single event can be calculated using the binomial probability formula:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

X = the number of successful outcomes (in this case, the number of customers who have looked at their credit score in the past six months)

k = the number of successful outcomes we want to know the probability of (in this case, 25)

n = the total number of trials or customers (in this case, 29)

p = the probability of a successful outcome (in this case, 0.67 or 67%)

Answer:

b) 270

Step-by-step explanation:

a)

(√5)² = 5

(√3)² = 3

This is due to the square root and to the power of 2 cancelling each other out if that makes sense. It's the same with (√3)²

So all you're actually doing is 5 × 3 which is 15

b)

It's basically the same except (³√9)³ is cube(d) root and to the power of 3
