Answer:

\(x=\frac{3}{2} - i\frac{\sqrt{7}}{2}\)

\(x=\frac{3}{2} + i\frac{\sqrt{7}}{2}\)

Step-by-step explanation:

We can use the quadratic formula to solve the equation:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = -3, and c = 4. Substituting these values into the formula, we get:

x = (3 ± sqrt((-3)^2 - 4(1)(4))) / 2(1)

x = (3 ± sqrt(9 - 16)) / 2

x = (3 ± sqrt(-7)) / 2

Since the square root of a negative number is not a real number, the solutions to the quadratic equation are complex numbers. Therefore, the answer is:

\(x=\frac{3}{2}+i\frac{\sqrt{7} }{2}\)

\(x=\frac{3}{2} - i\frac{\sqrt{7}}{2}\)

The median number of newspapers sold over seven weeks is 223.

The median is the middle score for a data set arranged in order of magnitude. The median is less affected by outliers and skewed data.

The formula for the median is as follows:

Find the median number of newspapers sold. (87, 87, 215, 154, 288, 235, 231)

We'll first arrange the data in ascending order.87, 87, 154, 215, 231, 235, 288

The median is the middle term or the average of the middle two terms. The middle two terms are 215 and 231.

Median = (215 + 231)/2

= 446/2

= 223

In statistics, the median measures the central tendency of a set of data. The median of a set of data is the middle score of that set. The value separates the upper 50% from the lower 50%.

Hence, the median number of newspapers sold over seven weeks is 223.

The measure that could be the side lengths of a right triangle is 30 cm, 72 cm, 78 cm, the correct option is B.

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.

We are given that;

The right triangle

Now,

We can use this equation to test each option by plugging in the values and checking if they satisfy the equation.

A. 7 cm, 21 cm, 25 cm

7^2 + 21^2 = 25^2

49 + 441 = 625

490 = 625

False

This option does not satisfy the Pythagorean theorem, so it cannot be the side lengths of a right triangle.

B. 30 cm, 72 cm, 78 cm

30^2 + 72^2 = 78^2

900 + 5184 = 6084

When we describe relationships between variables, a correlation nearer to 1.00 (plus or minus) indicates the relationship between variables is strong.

The strength and direction of a relationship between two or more variables are described by the statistical measure of correlation, which is given as a number. However, a correlation between two variables does not necessarily imply that a change in one variable is the reason for a change in the values of the other.

When correlation is known, predictions can be made using it. Knowing a score on one measure helps us predict another that is closely related to it more accurately. The forecast will be more accurate the stronger the correlation between/among the variables.

On simplifying the above equation, 5dk - 1 - 6dk - 2 = -3k + 7 = 3k - 2k = dk. Thus, we have proved that the sequence satisfies the recurrence relation for every integer k ≥ 2.

Given that the sequence is defined as dn = 3n − 2n for every integer n ≥ 0. We need to fill in the blanks to show that d0, d1, d2, …

satisfies the following recurrence relation dk = 5dk − 1 − 6dk − 2 for every integer k ≥ 2.

By definition of d0, d1, d2, …, for each integer k with k ≥ 2, in terms of k,dk = 3k - 2kdk - 1 = 3(k-1) - 2(k-1)dk-2 = 3(k-2) - 2(k-2)

For k ≥ 2, let's substitute (*) dk - 1 as 3(k-1) - 2(k-1), (**) dk - 2 as 3(k-2) - 2(k-2),

which means, dk = 5dk - 1 - 6dk - 2= 5(3(k-1) - 2(k-1)) - 6(3(k-2) - 2(k-2))= 5(3k - 3 - 2k + 2) - 6(3k - 6 - 2k + 4)= 15k - 15 - 10 + 10 - 18k + 36 + 12k - 24= -3k + 7

On simplifying the above equation, 5dk - 1 - 6dk - 2 = -3k + 7 = 3k - 2k = dk

Thus, we have proved that the sequence satisfies the recurrence relation for every integer k ≥ 2.

The central limit theorem states that if we draw a simple random sample (SRS) from any population, regardless of the shape of the population distribution.

The sampling distribution of the sample mean will be approximately normal if the sample size is large enough. This means that the mean of the sampling distribution will be the same as the mean of the population, and the standard deviation of the sampling distribution will be the standard error of the mean, which is equal to the standard deviation of the population divided by the square root of the sample size. Therefore, the central limit theorem allows us to make inferences about the population mean based on the sample mean, as long as we have a large enough sample size.
According to the Central Limit Theorem, if we draw a Simple Random Sample (SRS) from any population, the sampling distribution of the sample mean will APPROXIMATELY be normal, not exactly normal. This approximation improves as the sample size increases, especially when the sample size is large (usually n ≥ 30). The Central Limit Theorem allows us to make inferences about the population based on the sampling distribution.

The value of tan 0, where O is an acute angle in Quadrant 1 and sin O = 0.28, is approximately 0.292.

To find the value of tan 0, we can use the relationship between sine and tangent. The tangent of an angle is equal to the sine of the angle divided by the cosine of the angle. Since we know that sin O = 0.28, we need to find the value of cos O to calculate tan O.

In Quadrant 1, cos O is positive. We can use the Pythagorean identity sin^2 O + cos^2 O = 1 to find cos O. Since sin O = 0.28, we have (0.28)^2 + cos^2 O = 1. Solving for cos O, we find cos O ≈ 0.96.

Finally, we can calculate tan O by dividing sin O by cos O: tan O = sin O / cos O ≈ 0.28 / 0.96 ≈ 0.292.

Hence, the value of tan 0, where O is an acute angle in Quadrant 1 with sin O = 0.28, is approximately 0.292.

wow, this is kinda complicated math for HS..  :?   we have to know what type of series this is, and that means knowing all the different kinds.. unless maybe in the instructions it tells you you are working with arithmetic series? It is one of those so we can use those formulas... other series can have much more complex formulas..  series comes up in Calc II in college.. but .. unless you're going to be an engineer you probably don't need it..  soooooo anyway..

we can use  Sn = n/2(2a1 + d(n-1) )

where d is the difference of a2 -a1 ( this will be the same for all terms)

since we're given Sn = 209 set the problem to 209 and solve for n  :/

sounds hard huh.. :?  let's see

209 = n/2( 2(4) + 3(n-1))

209 = n/2(8 + 3n-3)

209 = n/2(5+3n)

2*209 = n(5+3n)

418 = 3\(n^{2}\) + 5n

0 = 3\(n^{2}\) + 5n-418    ( use quadratic formula to find n )

( -5 ± \(\sqrt{5^{2}-4*3*(-418) }\)  ) / 2(3)

( -5 ±\(\sqrt{25+5016}\) ) / 6

( -5 ±\(\sqrt{5041}\) ) / 6

( -5 ± 71 ) / 6  ( they were nice to us and make it work out perfectly :)  )

positive route =  71-5 /6 = 66/6 =11

negative route = 71-(-5) /6  = 71+5/6 = 76/6 = 12\(\frac{2}{3}\)

since 12\(\frac{2}{3}\)  isn't going to really work for us... let's try 11

an= a1 + d(n-1)

an = 4 + 3(11-1)

an = 4 + 30

an = 34

now let's see if we can get 209 for our 11 terms of the series

Sn = 11/2(2(4) + 3(11-1))

Sn = 11/2(8 + 30)

Sn = 418 /2

Sn = 209  yay.. we got it.. it's the 11th term.. and thank you  quadratic formula.  You get a Christmas present this year  :P

n = 11

The number of the terms of the sequence will be equal to 11.

The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.

Given series is  4+7+10+.....  and the sum of the terms of the series is 209.

The summation of the n terms of the series is written by the formula below,

Sn = n / 2 [( 2a+(n-1)d]

Substitute the values in the equation above,

209 = n / 2 [(2 x 4 + ( n -1)3]

418 = n(5+3n)

3n² + 5n - 418 = 0

The above quadratic equation will give two values of n. The values of n are,

n = 11

n = -12.55

The terms can not be equal to a negative number.

Therefore, the number of the terms of the sequence will be equal to 11.

a.  The sample size must be at least 8 to have a 95% confidence interval estimate for the gain in a circuit on a semiconductor device with a length of not greater than 60. b. The sample size must be at least 22 to have a 99% confidence interval estimate for the gain in a circuit on a semiconductor device with a length of not greater than 60.

a. The formula for finding the width of a confidence interval is:
Width of confidence interval = 2 × Zα/2 × σ/√n

where Zα/2 is the Z-score for the desired level of confidence.

For 95% confidence level, Zα/2 = 1.96.

Width of 95% confidence interval = 60σ = 30Zα/2 = 1.96

Substituting the given values in the formula:60 = 2 × 1.96 × 30/√nn = (2 × 1.96 × 30/60)²n = 7.84≈ 8

Therefore, the sample size must be at least 8 to have a 95% confidence interval estimate for the gain in a circuit on a semiconductor device with a length of not greater than 60.

b. For a 99% confidence level, Zα/2 = 2.576

Width of 99% confidence interval = 60σ = 30Zα/2 = 2.576

Substituting the given values in the formula:

60 = 2 × 2.576 × 30/√nn = (2 × 2.576 × 30/60)²n = 21.16≈ 22

Therefore, the sample size must be at least 22 to have a 99% confidence interval estimate for the gain in a circuit on a semiconductor device with a length of not greater than 60.
