Answer and Step-by-step explanation:

It ensures that you don't accidently skip a step or get confused by which numbers are being used. By writing it down, it allows you to look back and see if you answer was correct or incorrect.

For example:

On a test, you need to do a complicated math problem that you know you can do in your head. It would still be a good idea to write down the process, so that you can see in front of you the numbers you get and results. If it is incorrect when checking over you answers, then you can go through the steps you made to see where you made a mistake.

Step-by-step explanation:

The value of x in the given triangle is 12, Option C is correct.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

here, we have,

from the given figure, we get,

The given triangle is a right angled triangle.

We need to find the value of x.

We know that cosx is adjacent side by hypotenuse.

Cos 37 = Adjacent side/ Hypotenuse

The value of cos37 degrees is 0.7654

0.7654 = x/15

15×0.7654=x

11.5 =x

12=x

Hence, The value of x in the given triangle is 12, Option C is correct.

Answer: x-4>-9 or x-4<9

Step-by-step explanation:

The correct option for the given inequality is x-4>-9 or x-4<9

A relationship between two expressions or values that are not equal to each other is called inequality.

Given an inequality, |x-4| < 9

Using the rule, if |x| < a then, -a < x < a.

Therefore,

|x-4| < 9

-9 < x-4 < 9

x-4 > -9 or x-4 < 9

Hence, The correct option for the given inequality is x-4>-9 or x-4<9

Step-by-step explanation:

Sometimes, the best way to answer a multiple-choice question is to see which choices are self-consistent.

__

Side lengths and their opposite angle measures in a triangle have the same ordering, least to greatest. It is informative to look at the answer choices with this in mind.

1a. C < A < B; a < c < b . . . . inconsistent

2a. C < A < B; c < a < b.

2b. C < A < B; c < a < b . . . . consistent

3a. B < A < C; c < a < b . . . . inconsistent

4a. B < A < C; a < c < b . . . . inconsistent

Only answer choice 2 is self-consistent. It is the correct one.

Answer:

Test statistic = - 3.354

We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.

Step-by-step explanation:

H0 : μ = 3

H1 : μ < 3

The test statistic = (xbar - μ) / (s/ √n)

Xbar = 1.50

μ = 3

s = 3

n = 45

Test statistic = (1.5 - 3) / (3/ √45)

Test statistic = - 1.5 / 0.4472135

Test statistic = - 3.354

Pvalue, using the Pvalue from Z score calculator :

Pvalue = 0.00039826

α = 0.05

Pvalue < α ; We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.

Answer:

0.75 = 75% probability that he will have to wait at a red light for more than 15 seconds

Step-by-step explanation:

At each second, the stoplight is equally likely to change, which means that we use the uniform probability distribution to solve this question.

Uniform probability distribution:

Has two bounds, a and b. The probability of finding a value higher than x is given by:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

Red for 60 seconds

So when Jamal arrives it can change in any number of seconds between 0 and 60, that is, [tex]a = 0, b = 60[/tex]

Probability that he will have to wait at a red light for more than 15 seconds?

[tex]P(X > 15) = \frac{60 - 15}{60 - 0} = \frac{45}{60} = \frac{3}{4} = 0.75[/tex]

0.75 = 75% probability that he will have to wait at a red light for more than 15 seconds

Answer:

diagonally.

Step-by-step explanation:

the vertices are the corners or angles. square has four angles. if you have to divide it in half by connecting 2 vertices, then you would just need to draw a line from one corner, diagonally to another corner. you have 2 halves that are equilateral triangles. think about a grilled cheese sandwich cut in half. make sense?

Answer:

mean = 10.2 minutes

median = 9.5 minutes

Step-by-step explanation:

To find the mean, add up all of the results and then divide by the number of students in the sample. Therefore, the work should look like this: 15+8+7+7+11+13=61  --> 61/6=10.1666667

To find the median, order the results from least to greatest and then notice which number is the middle value. Since there is an even number of students in the sample, you will find that both 8 and 11 are the middle values when you put them all in numerical order (7, 7, 8, 11, 13, 15). Therefore, you must find the average of those two number in order to get the median. (8+11=19 --> 19/2=9.5)

Answer:

68% of the population will have a height between 64 and 72 inches

Step-by-step explanation:

According to the Empirical Rule, 68% of the population will have a height within the range of 1 standard deviation of the mean. This means that the range of possible heights for 68% of the population is between 68-4(1)=64 inches and 68+4(1)=72 inches
