Answer:1.02 5.27 are correct

Step-by-step explanation:We can solve this quadratic equation in cos(θ) by using the substitution u = cos(θ):

3u^2 + 6u - 4 = 0

Now we can use the quadratic formula to solve for u:

u = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 3, b = 6, and c = -4. Substituting these values, we get:

u = (-6 ± sqrt(6^2 - 4(3)(-4))) / 2(3)

u = (-6 ± sqrt(84)) / 6

u = (-3 ± sqrt(21)) / 3

Answer:

1: The correction option is B) Negative

Explanation

In economic theory, the Philips curve depicts the relationship between unemployment and inflation as a negative one. In order words, when inflation goes up, unemployment reduces.

The logic behind that thinking is, that inflation, which is the general increase in prices of goods/commodities and services is good for business. Business owners are quick to adjust to higher prices regardless of how it is induced and sometimes even profit from it in sectors not affected by inflation. So in such sectors, as business improves,  it is assumed that there is a requirement to being in more hands to help with the expansion of the business.

2. The correct option is B) Holds for certain time periods

Explanation

Social scientists and researchers have plotted the data across various periods (20 years) using data from the US economy.

The following results emerged:

So the correct answer is B.

3. The correct answer is True:

Explanation

As seen from the analysis above, the negative relationship remains largely true for most of the periods examined. Hence it is more pragmatic to expect a dip in unemployment whenever there is a spike in the CPI.

The balance in Lee's account at the end of 6 years is $384,830.53.

The first step is to determine the future value of the initial amount deposited in the savings account.

Rotating the area bounded by the given curves around the designated line yields the solid's volume as \(V = \frac{9}{22}\pi\)

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere. Different forms have various volumes.

The amount

of space that a solid occupies is measured by its volume. The amount of unit cubes required to completely fill the solid serves as the measurement. The capacity of an object to hold matter is generally thought of as its volume in three dimensions.
The functions provided are,

\(`y = f(x) = \sqrt{x}``y = g(x) = x^5`\)

By rotating the area around the x-axis, the solid's volume is given by (using washer method)
\(V = \pi int_a^b [f^2(x)-g^2(x)]dx\)
evaluate the integral, limit the plugins, and
\(V = \pi int_0^1 [(\sqrt{x})^2-(x^5)^2]dx\\\\V= \pi int_0^1 [x-x^10]dx V = \pi [\frac{x^2}{2}-\frac{x^11}{11}]_0^1 V = \pi [\frac{1^2}{2}-\frac{1^11}{11}]. V = \pi [\frac{1}{2}-\frac{1}{11}] = \frac{9}{22}\pi\)

Answer:

The school paid for printing 130 T-shirts

Step-by-step explanation:

Function Models

We are given the cost of printing n T-shirts as the equation:

\(C=250+5.5n\)

For example, if 10 T-shirts were printed, the school would pay:

\(C=250+5.5(10)=250+55=\$305\)

We know the school paid $965 and are required to find the number of T-shirts that were printed. If we use the equation with C=965, we can solve it for n:

\(965=250+5.5n\)

\(965-250=5.5n \Rightarrow 5.5n=715\)

Solving:

\(n=715/5.5=130\)

The school paid for printing 130 T-shirts

The categorical data in the table is the number of holes (option 1).

Categorical variables are variables that can only take on a fixed or a limited number of values. Categorical variables are examples of qualitative data.

Categorical variables can be binary. This mean that they can either have two values. An example of categorical variable is yes or no. Binary variables can also be called  dichotomous variable. A categorical variable is polytomous if can have more than two values.

In this question, the maximum hole number possible is 18 holes. The number of holes cannot exceed this number. Thus, the hole number is limited or fixed. Thus, hole number is a categorical data.

Answer:

a

The confidence interval for the population variance is ​\( 5.49 < \sigma^2 < 37.02 \)  

The correct option is  C

b

The confidence interval for the population standard deviation is \( 2.34 < \sigma < 6.08 \)

The correct option is  A

Step-by-step explanation:

From the question we are told that

    The sample size is  n =  14

    The standard deviation is  \(s = \$3.42\)

Generally the degree of freedom is mathematically represented as

     \(df =  14 -1\)

=>   \(df =  13 \)    

Given that the confidence level is  98%  then that level of significance is  

     \(\alpha = (100 -98) \%\)

=>  \(\alpha = 0.02\)

Generally the 98% confidence interval for the variance  is mathematically represented as

     \(\frac{(n- 1) s^2}{x^2 _{[\frac{\alpha }{2} , df]}}  < \sigma^2 < \frac{(n- 1) s^2}{x^2 _{[1- \frac{\alpha }{2} , df]}}\)

=> \(\frac{(14- 1) (3.42)^2}{x^2 _{[\frac{0.02 }{2} , 13]}}  < \sigma^2 < \frac{(14- 1) (3.42)^2}{x^2 _{[1- \frac{0.02 }{2} , 13]}}\)

From the chi -distribution table  

     \(x^2 _{[1- \frac{0.02 }{2} , 13]} = 4.107\)

and

    \(x^2 _{[\frac{0.02 }{2} , 13]} = 27.689\)

So

=> \(\frac{(14- 1) (3.42)^2}{27.689}  < \sigma^2 < \frac{(14- 1) (3.42)^2}{4.107}\)    

=> \( 5.49 < \sigma^2 < 37.02 \)    

Generally the 98% confidence interval for the standard deviation   is mathematically represented as

   \(\sqrt{\frac{(n- 1) s^2}{x^2 _{[\frac{\alpha }{2} , df]}}}   < \sigma <\sqrt{ \frac{(n- 1) s^2}{x^2 _{[1- \frac{\alpha }{2} , df]}}}\)

=> \(\sqrt{5.49}  < \sigma < \sqrt{37.02 }\)

=> \( 2.34 < \sigma < 6.08 \)

Step-by-step explanation:

Answer:

2 miles per hour.

Step-by-step explanation:

When the boat is traveling upstream (against the current), its effective speed is reduced by the speed of the current. Therefore, the boat's speed relative to the ground (or still water) during the upstream trip is 11 - c miles per hour.

Similarly, when the boat is traveling downstream (with the current), its effective speed is increased by the speed of the current. Therefore, the boat's speed relative to the ground during the downstream trip is 11 + c miles per hour.

Given that the boat takes 26 minutes (or 26/60 hours) to make the upstream trip and 18 minutes (or 18/60 hours) to make the downstream trip, we can set up the following equations:

Distance = Speed × Time

For the upstream trip:

Distance = (11 - c) × (26/60)

For the downstream trip:

Distance = (11 + c) × (18/60)

Since the distances traveled in both directions are the same (as the boat goes to the same point and returns), we can equate the two equations:

(11 - c) × (26/60) = (11 + c) × (18/60)

Let's solve this equation to find the value of "c" (the speed of the current):

(11 - c) × (26/60) = (11 + c) × (18/60)

(11 - c) × 26 = (11 + c) × 18

286 - 26c = 198 + 18c

44c = 88

c = 88/44
