The required solution to the trigonometry equation is x = π/4 + π n.

The equation of trigonometry functions is given in the question as

secx - cscx = 0

We have to determine the solution to the given equation

As per the question, we have

⇒ secx - cscx = 0

⇒ 1/cosx - 1/sinx = 0

⇒ (-cosx + sinx)/cosxsinx = 0

Using property : f(x)/g(x) = 0 ⇒ f(x) = 0

⇒ -cosx + sinx = 0

Divided by cosx into the equation,

⇒ -1 + tanx = 0

⇒ tanx  = 1

The general solution for tan tanx  = 1 is

⇒ x = π/4 + π n

The acceleration of the truck when it has a mass of 5000 kg and the truck driver presses on the brakes is 1.2m/s².

The rate of change of an object's velocity with respect to time is defined as acceleration. Vector quantities are accelerations.

The orientation of an object's acceleration is determined by the orientation of the net force acting on that object's acceleration, which is the rate at which velocity changes over time in terms of both speed and direction. A point or object moving in a straight line is accelerated if it accelerates or decelerates.

Acceleration will be:

= Force / mass

= 6000 / 5000

= 1.2 m/s²

The confidence interval for a proportion should be constructed since the variable of interest is a person's opinion, which is a qualitative variable.

A trait that cannot be quantified is referred to as a categorical variable (also known as a qualitative variable).

Nominal or ordinal categorical variables are also acceptable.

Since the variable of interest is a person's opinion, which is a qualitative variable, the confidence interval for a proportion should be built.

Statistical Variables Qualitative variables also referred to as categorical variables are variables without a built-in sense of hierarchy.

As a result, they are quantified using a nominal scale.

For instance, a qualitative variable is a name as well as hair color (Black, Brown, Gray, Red, Yellow).

Therefore, the confidence interval for a proportion should be constructed since the variable of interest is a person's opinion, which is a qualitative variable.

Answer:

Yes, the point (-7, 5) satisfies the inequality y > -3/7x + 2

Step-by-step explanation:

Plug in the values to the inequality and verify if it is true:

x = -7, y = 5

5 > (-3/7*-7) + 2

5 > (-3/-49) + 2

5 > 3/49 + 2

5 > 101/49

The inequality above is true (5 is greater than 101/49 [101/49 is about 2.06]), so the point (-7, 5) satisfies y > -3/7x + 2

Answer: $38.50 per month

Step-by-step explanation: We have to find 10% of 35 and add it to 35. This is because 10% of 35 is the amount that will increase so adding that to the original 35 will be her new premium. 10% of 35 is $3.50 and $3.50 + $35 is $38.50. This means her new premium is $38.50 per month.

With the help of unitary method , we can say that ,To create a batch of 15%-pigment paint, he needs to mix 98.57 liters of the 27%-pigment paint with the 12%-pigment paint.

Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.

Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.

Imagine that your square is made up of smaller unit squares.

The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.

To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.

According to our question-

Paint volume times pigment concentration equals pigment amount.

or

V × c = P

If the three options are referred to as 1, 2, and 3, then

P₁ + P₂ = P₃

V1c1 = V2c2 + V3c3

Let x equal the paint's 11% volume.

Then

230 × 21 % + x × 11 % = (230 +x) × 18 %

Add 4830 plus 11x to get 4140 plus 18x, then take 4140 away from each side.

690 + 11x = 18x Take 11 times off of each side.

Divide each side of 690 by 7 to get the answer.

x = 98.57 L

The worker needs to add 98.57 L of the paint with a 21% pigment.

With a 95% confidence interval, the proportion of all shrubs of this species that will resprout after a fire is between 0.17 and 0.67.

What is a confidence interval?

An area surrounding a measurement that indicates how accurate it is called a confidence interval.

Here, we have

Confidence interval is written as

Sample proportion ± margin of error

Margin of error = z × √pq/n

Where

z represents the z score corresponding to the confidence level

p = sample proportion. It also means the probability of success

q = probability of failure

q = 1 - p

p = x/n

Where

n represents the number of samples

x represents the number of success

From the information given,

n = 14

x = 6

p = 6/14 = 0.42

q = 1 - 0.42 = 0.58

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

This is the area in each tail.

Since we want the area in the middle, it becomes

1 - 0.025 = 0.975

The z score corresponding to the area on the z table is 2.05. Thus, Thus, the z score for a confidence level of 95% is 1.96

Therefore, the 95% confidence interval is

0.42 ± 1.96√(0.58)(0.42)/14

The lower limit of the confidence interval is

0.42 - 0.25 = 0.17

The upper limit of the confidence interval is

0.42 + 0.25 = 0.67

Hence, with a 95% confidence interval, the proportion of all shrubs of this species that will resprout after a fire is between 0.17 and 0.67.

What is milk?

A white liquid meal called milk is generated by mammals' mammary glands. Before they can digest solid food, it is the main source of nutrition for young mammals. Milk immunity is influenced by immune components and immune-modulating elements.

Given:

There are a cup of milk and a cup of water.

Take one teaspoon of milk, put into the water cup; mix well.

Take one teaspoon of the mixture in the water cup and put into the milk cup then mix well.

Suppose the percentage of water cup are 'p' and the percentage of milk cup are 'q'.

When we add one teaspoon of milk and put into water cup then the percentage of water cup are 'p + 1'.

And the percentage of milk cup are 'q - 1'.

Again one teaspoon of mixture in the water cup put into the milk cup.

So, the percentage of milk cup are, q - 1 + 1 = q.

And the percentage of water cup are p + 1 - 1 = p.

For the two lines to be parallel, the value of n must be 3

When two straight lines are plotted on the coordinate plane, we can tell if they are parallel from the slope, of each line. If the slopes are the same then the lines are parallel.

The slope of each line is calculated as (y2-y1)/x2-x1

for line AB, the slope = (6n-n)/10-4 = 5n/6

for line CD, the slope= 8n-(-6)/9-(-3)=( 8n+6)/12

for AB and CD to be parallel,

5n/6 = (8n+6)/12

multiply both sides by 12

10n= 8n+6

collect like terms

10n-8n= 6

2n= 6

n= 6/2= 3

The largest possible value for the decimal $a. B + c. D$  us:

Given that a, b, c, and d are different numbers (from 1 to 9), we are to find the largest possible value of a.b + c.d.

This problem can be answered by trial and error and with some logic. Clearly, a to d cannot be at the lower end of the values (1 to 5). Since the digits must be different, it can be a combination of digits from 6 to 9.

It is rather tempting to say that the 9.8 + 7.6 would yield the highest possible sum (=17.4) but this is incorrect. Since it is the sum of two numbers with a decimal, we have to maximize on the ones digit first before maximizing the tenths digit. Therefore: the combination of numbers must then be:

9.7 + 8.6 which results to 18.3

9.6 + 8.7 yields 18.3 as well.

The mean service time from the ​customers are between 161.5 to 164.7 seconds.

The trade magazine QSR routinely checks the​ drive-through service times of​ fast-food restaurants.

A 90% confidence interval that results from examining 607 customers in Taco Bell's drive-through has a lower bound of 161.5 seconds and an upper bound of 164.7 seconds.

Let's denote the mean service time by μ. Then, note that, we are given that n=607. Also, we are said that a 90% CI for μ is given by

(161.5,164.7)

This implies that we are 90% confident that μ lies in the interval. Or to be precise, this interval is a realization of a random interval that has 90% probability of covering the true mean. Thus, we are 90% confident that the mean service times of the restaurants are between 161.5 to 164.7 seconds.
