-Chetan K

Answer:

c. 25°

Step-by-step explanation:

Sum of angles in a triangle:

The sum of the measures of the angles of a triangle is 180º.

In this question:

Angles of 3x, 2x-13 and 5x + 3.

The sum is 180º. So

[tex]3x + 2x - 13 + 5x + 3 = 180[/tex]

[tex]10x - 10 = 180[/tex]

[tex]10x = 190[/tex]

[tex]x = \frac{190}{10}[/tex]

[tex]x = 19[/tex]

Measure of each angle:

3x = 3(19) = 57º

2x - 13 = 2(19) - 13 = 38 - 13 = 25º

5x + 13 = 5(19) + 3 = 95 + 3 = 98º

The smallest angle is 25º, and the correct answer is given by option c.

THE ANSWER IS :13,000

Answer:

- 1 5/24 cm

Step-by-step explanation:

We'll have to get the fractions to a common denominator. the least common denominator for 3 and 80 is 240.

So - 1 1/3 = - 1 80/240 = 320/240

21/80 = 63/240

-11/80 = -33/240

-------------------------------------

-320/240 + 63/240 - 33/240 = -290/240 = - 1 50/240 = -1 5/24 cm

The total change in the water level is [tex]-\frac{29}{24}[/tex]

'A fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole.'

According to the given problem,

Change in first month =  [tex]([/tex][tex]-1\frac{1}{3}[/tex] [tex])[/tex] + [tex]\frac{21}{80}[/tex] + [tex](-\frac{11}{80})[/tex]

                                    =   [tex]([/tex][tex]-1\frac{1}{3}[/tex] [tex])[/tex]  + [tex]\frac{10}{80}[/tex]

                                    =   [tex]([/tex][tex]-1\frac{1}{3}[/tex] [tex])[/tex] + [tex]\frac{1}{8}[/tex]

                                    = [tex]\frac{1}{8} - \frac{4}{3}[/tex]

                                    = [tex]\frac{3 - 32}{24}[/tex]

                                    = [tex]-\frac{29}{24}[/tex]

Hence, we can conclude, the change in the water level is  [tex]-\frac{29}{24}[/tex]

Answer:

c. 6.2 ± 2.626(0.21)

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 101 - 1 = 100

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 100 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.626

The confidence interval is:

[tex]\overline{x} \pm M[/tex]

In which [tex]\overline{x}[/tex] is the sample mean while M is the margin of error.

The distribution of the number of puppies born per litter was skewed left with a mean of 6.2 puppies born per litter.

This means that [tex]\overline{x} = 6.2[/tex]

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.626\frac{2.1}{\sqrt{101}} = 2.626(0.21)[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

Thus, the confidence interval is:

[tex]\overline{x} \pm M = 6.2 \pm 2.626(0.21)[/tex]

And the correct answer is given by option c.
