Step-by-step explanation:

49/6 or 8 1/6

Answer: 0.086

Explanation: There are 1,000 milliliter in a liter. Since 86 is below 1,000, your answer won’t be in front of the decimal. For example, if you had 3,000 milliliters, your answer would be 3.0 liters.

Answer:

this is not a function

Step-by-step explanation:

Answer:

if I am guessing this is trigonometry

First is to look at what sides you have in which you have the legs. This means you can use tangent. how ever you need to use arctangent or

tan^-1 to find the angle.

the way you set this up in your calculator is tan^-1(8.4÷15.2). plus be sure it's on Deg not Rad.

This leaves the answer if 28.9°

Answer:

This is a voluntary response sample and likely overestimates the frequency of exercise.

Step-by-step explanation:

I just took the unit test review.  The people taking the survey took it voluntarily and it overestimates exercise because it was offered to gym members.

The statement describes the bias that may arise from the results is "This is a voluntary response sample and likely overestimates the frequency of exercise".

Given that,

A nutritionist would like to estimate the number of times adults exercise each week.

To collect information, the nutritionist emails the members of the local fitness center.

We have to determine,

Which of the following describes the bias that may arise from the results?

Answer:

Step-by-step explanation:

Large sheet:

 Length = 9 inches

 Width of large sheet = area ÷ length = 5 inches

 ratio of length to width = 9:5

Small sheet:

 Length = 4 inches

 Width = 3 inches

 ratio of length to width = 4:3

9:5 ≠ 4:3

The sheets are not similar

The large sheet and small sheet are not similar because they have different dimensions.

What is the area of a rectangle ?

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.

It is given that large sheet has a length of 9 inches and an area of 45 square inches whereas the small sheet has length of 4 inches and a width of 3 inches.

Let's find out the area of small sheet which will be :

A = L × B

A = 4 × 3

A = 12 inches²

Whereas , in case of large sheet the area is 45 inches². So , the area of both sheets are not similar.

Let's check if dimensions are same.

Width of large sheet will be :

A = L × B

45 = 9 × B

or

B = 5 inches

So , dimensions are also not equal.

Therefore , the large sheet and small sheet are not similar because they have different dimensions.

Answer:

The lenghts of the sides are: 8 inches, 32 inches, 36 inches.

Step-by-step explanation:

Perimeter of a triangle:

The perimeter of a triangle is given by the sum of it's sides dimensions.

The ratio of the measures of the sides of a triangle is 2:8:9.

This means that their measures are:

The first measure is x

The second measure is of: [tex]\frac{8x}{2} = 4x[/tex]

The third measure is of [tex]\frac{9x}{2}[/tex]

So the perimeter will be of:

[tex]x + 4x + \frac{9x}{2} = 76[/tex]

[tex]5x + \frac{9x}{2} = 76[/tex]

[tex]\frac{10x}{2} + \frac{9x}{2} = 76[/tex]

[tex]\frac{19x}{2} = 76[/tex]

[tex]19x = 76*2[/tex]

Simplifying by 19

[tex]x = 4*2 = 8[/tex].

So, dimensions of:

[tex]8, 4*8 = 32, \frac{9*8}{2} = 36[/tex]

The lenghts of the sides are: 8 inches, 32 inches, 36 inches.

ANSWER

0.08 then 0.7 then 8/10 then 81%

Explanation

im going to put everything into fraction because i think it would be easier for u to understand

8/10 > 80/100

0.08> as a fraction is > 8/100

81% as a fraction is 81/100

and last but not least, 0.7 as a fraction is 70/100

so order these from least to greatest

8/100 then 70/100 then 80/100 and then 81/100.

so it would be

0.08 then 0.7 then 8/10 then 81%

Answer:

1. X=35 degrees obtuse

2 x=25 degrees right

Step-by-step explanation:

Background info:

The measures of the angels of every triangle is 180 degrees

So x equals 180 minus the other angles combined

1. X=180-(40+105)

X=180-145

X=35 degrees

2.

x=180-(90+65)

x=180-155

x=25 degrees

Answer:

j = -15

Step-by-step explanation:

Given that,

A line that includes the points (-9,-5) and (-10, j) has a slope of -10.

The slope of a line for which two points are given is :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\-10=\dfrac{j-(-5)}{-10-(-9)}\\\\10=\dfrac{j+5}{-10+9}\\\\10=\dfrac{j+5}{-1}\\\\-10=j+5\\\\j=-10-5\\\\j=-15[/tex]

So, the value of j is equal to -15.

Answer:

0.7780

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Population:

We have that [tex]\mu = 7.19, \sigma = 0.86[/tex]

Sample of 12:

[tex]n = 12, s = \frac{0.86}{\sqrt{12}} = 0.2483[/tex]

What is the probability that the mean cost will be more than $7.00?

This is 1 subtracted by the pvalue of Z when X = 7. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{7 - 7.19}{0.2483}[/tex]

[tex]Z = -0.765[/tex]

[tex]Z = -0.765[/tex] has a pvalue of 0.222

1 - 0.222 = 0.778

So the answer is 0.7780

Answer:

7.5

Step-by-step explanation:

The perimeter of the regular pentagon will be 7.5 units.

All the sides of the regular polygon are congruent to each other. The perimeter of the regular polygon of n sides will be the product of the number of the side and the side length of the regular polygon.

P = (Side length) x n

The sides of the regular polygon are 3(x - 1) and (5x - 6). Then the value of the variable x will be

3(x - 1) = 5x - 6

3x - 3 = 5x - 6

2x = 3

x = 1.5

Then the side length of the regular pentagon will be

Side = 3(1.5 - 3)

Side = 3 (0.5)

Side = 1.5

Then the perimeter of the regular pentagon will be

P = 5 x 1.5

P = 7.5 units

The perimeter of the regular pentagon will be 7.5 units.
