Last year, 50 students attended the winter carnival. This year, 60 students attended the carnival. Which statement below correctly describes the percent
change from last year to this year?
A
An increase of 10%
B
A decrease of 10%
С
An increase of 20%
D
A decrease of 20%

Answers

Answer 1

Answer:

C. An increase of 20%

Step-by-step explanation:

50/100 = 60/x

Cross products

50 x  =  6000

Divide 50 by both sides

x  =  120

60 is 120% of 50, so there is a 20% increase

Hope this helps!

Answers

Answer:

its not zero i check and got in incorrect the correct answer is 1

Step-by-step explanation:

Answer:

The answer is B) There is one proportional relationship

Step-by-step explanation:

The green line (the one at the top) does not go through the origin. This is not a proportional relationship.

Problem: It does not go through 0,0

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

The blue line (the one in the middle) is a straight line through the origin. This is a proportional relationship.

Reason: It goes through 0,0

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

The purple line (the one at the bottom) does not go through the origin. This is not a proportional relationship.

Problem: It does not go through 0,0

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

Conclusion: Since the green and purple lines are not proportional but the blue line is, this means only 1 line is proportional.

Complete the ordered pair for both equation. Will give brainiest

Answers

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

So if you know that order pairs go like (x,y) that means that the 12 in (12,y) is the x so if we plug into the equation we can get y...

[tex]y=\frac{2}{3} (12)+ 5\\y=8+5\\y=13[/tex]

So the order pair is (12, 13).

Now for the next one it's the same concept but this time we'll plug in for y because the -2 is in the (x, y) so we have to find the x...

[tex]5x-9(-2)=3\\5x+18=3\\5x=-15\\x=-3[/tex]

So the order pair is (-3, -2).

A professor of philosophy hypothesizes that an introductory course in logic will affect college students with their other studies. To test this hypothesis, a random sample of 25 first year students is selected. These students are required to complete a logic course during their first year. At the time of graduation, the final GPA is computed or each of these students. The mean GPA for this sample is 2.58 with a SS of 6.

Required:
Can the professor conclude that the grades for the sample were significantly different from the rest of the graduating class, which had an average GPA of 2.33?

Answers

Answer:

NO.

Step-by-step explanation:

The Professor's hypothesis:

An introductory course in Logic will affect college students with their other studies (will affect their Great Point Average - GPA).

25 students are used as the experimental group while the rest of the class are the control group.

The mean GPA in a sample size (SS) of 6 is = 2.58

The mean GPA in the full sample size of 25 would be = 10.75 by crossmultiplying.

This makes me believe the question was written wrongly. I assume SD (standard deviation) of 0.6 instead of SS (sample size) of 6.

Going by this, if standard deviation is 0.6 then the interval within which the GPA of the experimental group (the 25 students) falls is:

[2.58 - 0.6] to [2.58 + 0.6]

= 1.98 to 3.18

The rest of the graduating class (the control group) had a mean GPA of 2.33

Can the professor conclude that the GPA for the sample is significantly different from that of the control group?

The answer is NO because the GPA of the control group falls within the GPA interval of the experimental group!

Two boxes of chocolates cost Php180. How much do 7 boxes of chocolates cost? *what proportion is that?​

Answers

Answer:

Php630

Step-by-step explanation:

2 boxes of chocolates cost Php180.

Number of boxes : price

2 : 180

How much do 7 boxes of chocolates cost?

Let x = price of 7 boxes

Number of boxes : price

7 : x

Number of boxes : price

2 : 180 = 7 : x

2/180 = 7/x

cross product

2*x = 180*7

2x = 1,260

Divide both sides by 2

x = Php630

7 boxes of chocolates cost Php630

A researcher wants to compare the heights of males between generations to see if they differ. To do this, he samples random pairs of males who are at least 18 years old and their fathers. He then splits them into a sample of fathers and a sample of sons. Suppose that data were collected for a random sample of 11 pairs, where each difference is calculated by subtracting the height of the son from the height of the father. Assume that the heights are normally distributed. The test statistic is t≈1.971, α=0.05, the corresponding rejection regions are t<−2.228 and t>2.228, the null hypothesis is H0:μd=0, and the alternative hypothesis is Ha:μd≠0.

Select all that apply:
a. Reject the null hypothesis.
b. Fail to reject the null hypothesis.
c. The conclusion of the hypothesis test is that there is sufficient evidence to suggest that the heights of males between generations are different.
d. The conclusion of the hypothesis test is that there is insufficient evidence to suggest that the heights of males between generations are different.

Answers

Answer:

The correct option is  

Option A and Option C

Step-by-step explanation:

From the question we are told that

   The sample size of paired men is  [tex]n_p   =  11[/tex]

   The test statistics is  t≈1.971

    The  significance level is  α=0.05

    The rejection region is  t<−2.228 and t>2.228

    The null hypothesis is  [tex]H_o :\mu_ d=0[/tex]

     The alternative hypothesis  is  [tex]H_a :\mu_ d \ne 0[/tex]

Generally the degree of freedom is mathematically represented as

        [tex]df  =  n_1 +  n_2 - 2[/tex]

Here [tex]n_1[/tex] is the sample size of  father which is  [tex]n_1 =  11[/tex]

        [tex]n_2[/tex] is the sample size of males who are at least 18 years old  which is  [tex]n_2 =  11[/tex]

So

     [tex]df  =  11 +  11 - 2[/tex]

=>   [tex]df  =  20[/tex]

Generally the critical values of  α=0.05 from the  t- distribution table at a degree of freedom of  [tex]df  =  20[/tex]  for a two -tailed test  is  

     [tex]t_{0.05 , 20 } =  \pm 2.08596345  [/tex]

From the value  obtained we see that the critical value  is within the region of rejection hence

 The decision rule is

Reject the null hypothesis

The conclusion is  

  The conclusion of the hypothesis test is that there is sufficient evidence to suggest that the heights of males between generations are different.

Answer:

Step-by-step explanation:

it seems like you're asking what the solution of each equation is put into a fraction

so, putting in 3 for g gives you

[tex]3(3) + 5 = 14[/tex]

which then goes over

[tex]((3) - 1 = 2)((3) + 6 = 9) = 18[/tex]

which gives

[tex] \frac{14}{18} [/tex]

however, this can be reduced to

[tex] \frac{7}{9} [/tex]

because both 14 and 18 can be divided by 2.

Step-by-step explanation:

All of the digits in the given number are significant. There are 7 significant digits.

__

Comment on other cases

When there are non-zero digits to the left of the decimal point in a number with a decimal point, all of the digits are significant.

When there are no non-zero digits to the left of the decimal point, leading zeros are not significant. All digits following the leading zeros are significant.

In a number with no decimal point, the leading and trailing zeros are not significant.

If the number is written in scientific notation, all digits of the mantissa are significant. (This can be a way to ensure the correct number of significant digits is known in a number with trailing zeros.)

The authors of a certain paper describe a study to evaluate the effect of mobile phone use by taxi drivers in Greece. Fifty taxi drivers drove in a driving simulator where they were following a lead car. The drivers were asked to carry on a conversation on a mobile phone while driving, and the following distance (the distance between the taxi and the lead car) was recorded. The sample mean following distance was 3.80 meters and the sample standard deviation was 1.19 meters.
Construct a 95% confidence interval (in meters) for μ, the population mean following distance while talking on a mobile phone for the population of taxi drivers. (Round your answers to three decimal places.)

Answers

Answer:

The 95% confidence interval is  [tex] 3.462 <  \mu <  4.138 [/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  50  

    The sample mean is  [tex]\=  x =  3.80[/tex]

     The standard deviation is  [tex]\sigma  =  1.19[/tex]

Given that the confidence level is  95%  then the level of confidence is mathematically represented as

     [tex]\alpha =  (100 - 95)\%[/tex]

=>    [tex]\alpha =  0.05 [/tex]

Generally from the t distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of  [tex]df =  50 -1 = 49[/tex] is  

   [tex]t_{\frac{\alpha }{2} ,49 } =  2.0096[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

=>   [tex]E =2.0096 *  \frac{1.19}{\sqrt{ 50} }[/tex]

=>   [tex]E = 0.3381 [/tex]

Generally 95% confidence interval is mathematically represented as  

      [tex]\= x -E <  \mu <  \=x  +E[/tex]

      [tex] 3.80 -0.3381 <  \mu <  3.80 +0.3381[/tex]

=>    [tex] 3.462<  \mu <  4.138 [/tex]

A snail travels 10 cm and 4 minutes at this rate how long will it take for the snail to travel 24 cm?

Answers

Answer:

It will take 9.6 minutes to travel 24 cm.

Step-by-step explanation:

(;;;

Answer:

9.6 minutes.

Step-by-step explanation:

First we need to find how many minutes it takes the snail to travel 1 cm.

to do this we need to divide the time it takes by the distance traveled.

4 ÷ 10 = 0.4. So, the snail takes 0.4 minutes to travel 1 cm.

Next we need to find how long it takes to travel 24 cm.

to do do that we need to multiply how long it takes the snail to travel 1 cm by the number of cm it needs to travel.

0.4 x 24 = 9.6. So, it takes the snail 9.6 minutes to travel 24 cm.
