3x=9

x=3

3-50=-47

Step-by-step explanation:

The determinant of the given matrix is 22.

To calculate the determinant of the matrix, we can use the Laplace expansion along the first row.

Using this method, we get:

det = 4 * det\[\begin{array}{ccc}3&4\\-1&1\end{array}\] - 2 * det\[\begin{array}{ccc}4&4\\-1&1\end{array}\] - 2 * det\[\begin{array}{ccc}4&3\\-1&1\end{array}\]

To calculate each of the 2x2 determinants, we can again use the

Laplace expansion

along the first row. This gives:

det\[\begin{array}{ccc}3&4\\-1&1\end{array}\] = 3 * 1 - 4 * (-1) = 7

det\[\begin{array}{ccc}4&4\\-1&1\end{array}\] = 4 * 1 - 4 * (-1) = 8

det\[\begin{array}{ccc}4&3\\-1&1\end{array}\] = 4 * 1 - 3 * (-1) = 7

Substituting these values back into the original formula for the determinant, we get:

det = 4 * 7 - 2 * 8 - 2 * 7 = 28 - 16 - 14 = -2

Therefore, the determinant of the given matrix is -2.

This line has the smallest coefficient for x.

The length of AC cannot be determined based on the information provided.

The confusion earlier.

Given the information that Triangle ABC has a perimeter of 40 inches, we can proceed to find the length of AC.

Let's assume that AC has a length of x inches.

Since the perimeter of a triangle is the sum of the lengths of its sides, we can set up an equation:

AC + AB + BC = 40

Substituting the values in the equation, we have:

x + AB + BC = 40

Without any additional information or specific lengths for AB and BC, it is not possible to determine the exact value of x or AC.

The lengths of AB and BC could vary, resulting in different values for AC.

the prior haziness.

We can go on to find the length of AC now that we know Triangle ABC has a perimeter of 40 inches.

Assume for the moment that AC is x inches long.

We may create the equation AC + AB + BC = 40 since the perimeter of a triangle is equal to the sum of the lengths of its sides.

With the variables in the equation substituted, we get x + AB + BC = 40.

The exact value of x or AC cannot be calculated in the absence of any more details or precise lengths for AB and BC.

After the 10th iteration, the estimated value of the root obtained by the bisection method is approximately 0.517. Option B

To solve the equation cos(x) - x * e = 0 in the interval [0, 1] using the bisection method, we start by checking the function values at the endpoints of the interval.

For x = 0:

cos(0) - 0 * e = 1 - 0 = 1

For x = 1:

cos(1) - 1 * e ≈ 0.54 - 2.72 ≈ -2.18

Since the function values at the endpoints have opposite signs, we can apply the bisection method to find the root within the interval.

The bisection method involves repeatedly dividing the interval in half and checking the function value at the midpoint until a sufficiently accurate approximation is obtained. In this case, we will perform 10 iterations.

After the 10th iteration, the estimated value of the root obtained by the bisection method is approximately 0.517.

What is Normal Distribution?

We are given a Normal Distribution, which is a continuous probability distribution and is symmetrical around the mean. The shape of this distribution is like a bell curve and most of the data is clustered around the mean. The area under this bell-shaped curve represents the probability.  

How to use z-table?

Step 1: In the z-table, find the two-digit number on the left side corresponding to your z-score. (e.g 0.9 1.4, 2.2, 0.5, etc.)

Step 2:Then look up at the top of the z-table to find the remaining decimal point in the range of 0.00 to 0.09. (e.g. if you are looking for 0.95 then go for the 0.05 column)

Step 3:Finally, find the corresponding probability from the z-table at the intersection of step 1 and step 2. We want to find out the probability that what percentage of his times between pitches are longer than 31 seconds.

Here, In the given question: we have,

Mean=36 seconds

Standard deviation = 2.5 seconds

So,

For x>39

We want to find out the probability that what percentage of his times between pitches are longer than 39 seconds.

\(\begin{aligned}&P(X > 39)=1-P(X < 39) \\&P(X > 39)=1-P\left(Z < \frac{x-\mu}{F}\right) \\&P(X > 39)=1-P\left(Z < \frac{39-36}{2.5}\right) \\&P(X > 31)=1-P\left(Z < \frac{3}{2.5}\right) \\&P(X > 39)=1-P(Z < 1.2)\end{aligned}\)

The z-score corresponding to 1.2 is 0.8849

\(\begin{aligned}&P(X > 39)=1-0.8849 \\&P(X > 39)=0.1151 \\&P(X > 39)=11.51 \%\end{aligned}\)

Answer:

s(t)=21500(16)^t

Step-by-step explanation:

A. The solution to the congruence 3x - 107 ≡ 0 (mod 12) is x ≡ 1 (mod 12).

B. The solution to the congruence 5x + 3 - 102 ≡ 0 (mod 7) is x ≡ 6 (mod 7).

C. The solution to the congruence 66 + 9 ≡ 0 (mod 11) is x ≡ 4 (mod 11).

To solve modulo equations or congruences, we need to find values of x that satisfy the given congruence.

A. For the congruence 3x - 107 ≡ 0 (mod 12), we want to find an x such that when 107 is subtracted from 3x, the result is divisible by 12. Adding 107 to both sides of the congruence, we get 3x ≡ 107 (mod 12). By observing the remainders of 107 when divided by 12, we see that 107 ≡ 11 (mod 12). Therefore, we can rewrite the congruence as 3x ≡ 11 (mod 12). To solve for x, we need to find a number that, when multiplied by 3, gives a remainder of 11 when divided by 12. It turns out that x ≡ 1 (mod 12) satisfies this condition.

B. In the congruence 5x + 3 - 102 ≡ 0 (mod 7), we want to find an x such that when 102 is subtracted from 5x + 3, the result is divisible by 7. Subtracting 3 from both sides of the congruence, we get 5x ≡ 99 (mod 7). Simplifying further, 99 ≡ 1 (mod 7). Hence, the congruence becomes 5x ≡ 1 (mod 7). To find x, we need to find a number that, when multiplied by 5, gives a remainder of 1 when divided by 7. It can be seen that x ≡ 6 (mod 7) satisfies this condition.

C. The congruence 66 + 9 ≡ 0 (mod 11) states that we need to find a value of x for which 66 + 9 is divisible by 11. Evaluating 66 + 9, we find that 66 + 9 ≡ 3 (mod 11). Hence, x ≡ 4 (mod 11) satisfies the given congruence.

Modulo arithmetic or congruences involve working with remainders when dividing numbers. In a congruence of the form a ≡ b (mod m), it means that a and b have the same remainder when divided by m. To solve modulo equations, we manipulate the equation to isolate x and determine the values of x that satisfy the congruence. By observing the patterns in remainders and using properties of modular arithmetic, we can find solutions to these equations.

We can say with 90% confidence that the true mean pH level of the population lies between 4.293 and 4.507.

To find the 90% confidence interval estimate for the mean pH level, we need to use the following formula:

Confidence interval = sample mean ± margin of error

The margin of error depends on the level of confidence, the sample size, and the standard deviation. We can use a t-distribution to calculate the margin of error since the sample size is less than 30.

First, we need to find the t-value for a 90% confidence interval with 48 degrees of freedom (n - 1):

t-value = t(0.05, 48) = 1.677

where t(0.05, 48) is the t-value for a two-tailed test at the 0.05 level of significance with 48 degrees of freedom.

Next, we can calculate the margin of error:

Margin of error = t-value × (standard deviation / square root of sample size)

Margin of error = 1.677 × (0.35 / sqrt(49)) = 0.107

Finally, we can calculate the confidence interval:

Confidence interval = sample mean ± margin of error

Confidence interval = 4.4 ± 0.107

Confidence interval = (4.293, 4.507)

The equation sec(x) - csc(x)/sec(x) + csc(x) = tan(x) - 1/tan(x) + 1 can be simplified to 1 = 1, which means that the equation holds true for all values of x.

To solve the given equation, we'll start by simplifying the left-hand side (LHS). Using the trigonometric identities sec(x) = 1/cos(x) and csc(x) = 1/sin(x), we can rewrite the equation as (1/cos(x)) - (1/sin(x))/ (1/cos(x)) + (1/sin(x)).

To combine the fractions, we find a common denominator, which is cos(x) * sin(x). Multiplying the numerator and denominator of the first fraction by sin(x) and the numerator and denominator of the second fraction by cos(x), we get (sin(x) - cos(x))/ (sin(x) + cos(x)).

Next, we simplify the right-hand side (RHS) of the equation. The tangent function is defined as tan(x) = sin(x)/cos(x), so tan(x) - 1/tan(x) + 1 becomes (sin(x)/cos(x)) - 1/((sin(x)/cos(x))) + 1.

Simplifying the RHS further, we get (sin(x)/cos(x)) - (cos(x)/sin(x)) + 1 = \(\frac{(sin^{2} (x) - cos^{2} (x) + cos(x)sin(x))}{cosxsinx}\) + 1.

Using the trigonometric identity sin²(x) + cos²(x) = 1, we can simplify the numerator of the RHS to sin(x)cos(x) + cos(x)sin(x), which simplifies to 2cos(x)sin(x).

Now, the equation becomes (2cos(x)sin(x))/(cos(x)sin(x)) + 1 = 1 + 1.

Finally, cancelling out cos(x)sin(x) in the numerator and denominator, we obtain 1 + 1 = 2, which simplifies to 1 = 1. This shows that the equation is true for all values of x.

A negative exponent means the number of the exponent divide by the number. The the radius of beryllium atom is larger than the radius of a nitrogen atom by two times.

Given information-

The radius of a nitrogen atom is \( 5.6\times10^{-11} \) meters.

The radius of a beryllium atom is \(1.12 \times10^{-10}\) meters

A negative exponent means the number of the exponent divide by the number.

As the radius of the nitrogen atom is \( 5.6\times10^{-11} \) meters. Convert it in the power of negative exponent of 10.

Let the radius of the nitrogen is \(r\) mm. Thus,

\(r=5.6\times 10^{-11}\\ r=5.6\times 10^{-10-1}\\ r=5.6\times 10^{-10}\times10^{-1}\\ r=\dfrac{5.6\times 10^{-10}}{10} \\ r=0.56\times 10^{-10}\)

Now the base of the exponents of both the atoms are same. As the radius of the nitrogen atom is \(0.56\times 10^{-10}\) meters and the radius of the beryllium atom is \(1.12 \times10^{-10}\). Thus the radius of beryllium atom is larger.

To calculate how many times, the radius of beryllium atom should be divided by the radius of a nitrogen atom. Thus,
