An ABC News poll asked adults whether they felt genetically modified food was safe to eat. 35% felt it was safe, 52% felt it was not safe, and 13% had no opinion.

A random sample of 120 adults was asked the same question at a local county fair. 40 people felt that genetically modified food was safe, 60 felt that it was not safe, and 20 had no opinion.

At the 0.01 level of significance, is there sufficient evidence to conclude that the proportions differ from those reported in the survey?

Answers

Answer 1

Answer:

The proportions differ from those reported in the survey.

Step-by-step explanation:

The Chi-square goodness of fit test would be used to determine whether the proportions differ from those reported in the survey.

The hypothesis for the test can be defined as follows:

H₀: The proportions does not differ from those reported in the survey.

Hₐ: The proportions differ from those reported in the survey.

Assume that the significance level of the test is, α = 0.01.

The Chi-square test statistic is given by:

[tex]\chi^{2}=\sum\limits^{n}_{i=1}{\frac{(O_{i}-E_{i})^{2}}{E_{i}}}[/tex]

Consider the Excel sheet provided.

The Chi-square test statistic value is 191.32.

The p-value of the test is:

[tex]p-value=P(\chi^{2}_{(n-1)}>191.32)\\\\=\text{CHISQ.DIST.RT}(191.32,2)\\\\=0.0000[/tex]

The p-value of the test is very small. The null hypothesis will be rejected at 1% level of significance.

Thus, concluding that the proportions differ from those reported in the survey.

You can get 1 cookie for 42 cents or 8 cookies for $3.44. Which is the better deal? How do you know?

Answers

Answer:

The better deal is 1 cookie for 42 cents

Step-by-step explanation:

We need to find the price of 1 cookie when the cookies are 8 for 3.44

Divide the total price by the number of cookies

3.44/8

.43

We can get 1 cookie for 42 cents  or 1 cookie for 43 cents

The better deal is 1 cookie for 42 cents because it is less money.

The better deal is the cookie for 42 cents.
When you divide $3.44 by 8 you get 0.43. So that means for each of the eight cookies ,it’s 43 cents in that box. But when you do 42 cents times eight,(0.42 x 8 = 3.36). So if you got eight cookies with the (1 cookie for 42 cents ) it would be the better deal… even though your only saving only 8 cents or 0.08.

m∠DBC=(12x-18) and m∠ABD=(8x+30) what is the value for x ?

Answers

The value of x is 12.

Given that the angles are m∠DBC=(12X-18) and m∠ABD=(8x+30).

An angle is made when two rays are joined together at any common point.

We will find the value of x by equating both the given angles as

m∠DBC=m∠ABD

Now, we will substitute the values of angles as

12x-18=8x+30

Further, we will subtract 18 from both sides and simplify it as

12x-18+18=8x+30+18

12x=8x+48

Now, we will subtract 8x from both sides and simplify as

12x-8x=8x+48-8x

4x=48

Now, we will divide both sides by 4, we get

4x/4=48/4

x=12

Hence, the value of x when m∠DBC=(12x-18) and m∠ABD=(8x+30) is 12.

Answers

Option C) is correct which is Adam started the construction at the wrong place. He should have started at point R and drawn an arc across both rays.

According to the question we can see that Adam first draws an arc on a line and draws the bisector, which gives him the error.

We know that when we construct an angle bisector, first we put the compass on the point of the angle and make an arc and from that arc we make two arcs that intersect at a point. Then we draw a ray from the point of angle to that intersecting point which gives us the angle bisector.

Here Adam didn't draw the arc from point R.

Thus, Adam started the construction at the wrong place. He should have started at point R and drawn an arc across both rays.

When turning the decimal to a fraction how do I do that? I’m confused

Answers

Ok so I was very confused on this too. Not even going to lie to ya, I struggled with this for a long time. However once you get the hang of it, it's actually rather simple.

So, lets try a problem. What is 0.04 as a fraction?

Well, we know that 0.04 is 4%. And you can do [tex]\frac{4}{100}[/tex] which is 0.04, or 4%

Does that make sense? If not let me explain it a little more.

Well basically all you have to do is put that number over 100.

Here are some examples of decimals to percentage to fraction:

0.5 = 50% = [tex]\frac{50}{100}[/tex] or in simplest form [tex]\frac{1}{2}[/tex]

0.11 = 11% = [tex]\frac{11}{100}[/tex]

0.03 = 3% = [tex]\frac{3}{100}[/tex]

I really hope this helped you!!!

If not let me know how i can explain it and what doesn't make sense!

Answer: To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, [tex]\frac{6}{10}[/tex]. If needed, simplify the fraction.

Answers

Using the relation between velocity, distance and time, it is found that a rate of 102 km/h is needed for the rest of the trip to achieve the desired rate for the entire trip.

What is the relation between velocity, distance and time?

Velocity is distance divided by time, that is:

v = d/t.

For the first 120 km, the rate is of 90 km/h, hence the parameters are given as follows:

d = 120, v = 90.

Hence the time is given by:

90 = 120/t1

t1 = 120/90

t1 = 1.33 hours.

For the second part of the trip, the parameters are given as follows:

t = 1.25, v = 64.

The time is 1.25 hours because 15 minutes is one fourth(15/60) = 0.25 of an hour.

Hence the distance found as follows is:

64 = d/1.25

d = 1.25 x 64

d = 80

The distance for the first two parts is given by:

120 + 80 = 200 km.

This is equivalent to 7/8 of the trip, hence the total distance is:

7/8d = 200

d = 200 x 8/7

d = 228.57 km.

For a rate of 80 km, we have that the time has to be of:

80 = 228.57/t

t = 228.57/80

t = 2.86 hours.

The time of the first two parts is:

1.33 + 1.25 = 2.58 hours.

2.86 - 2.58 = 0.28 hours.

Hence the last 228.57 - 200 = 28.57 km have to be traveled in 0.28 hours, for a rate of:

v = 28.57/0.28 = 102 km/h.

A rate of 102 km/h is needed for the rest of the trip to achieve the desired rate for the entire trip.

Answers

Answer:

One geranium is $3

Step-by-step explanation:

Let r = roses and g = geraniums

14r + 8g = 122

12r + 12g = 120

Multiply first equation by -3 and the second by 2 (we are trying to get terms that cancel when we add the two equations)

-42r - 24g = -366

+24r + 24g = 240

Add

18r = 126

r = 7, so one rose is $7

Put this into either of the original equations

14(7) + 8g = 122

98 +8g = 122

8g = 24

g = 3, so one geranium is $3

Let x be the cost of roses and y be the cost of geraniums
122 = 14x + 8y
120 = 12x + 12y
1) solve for a variable
We can use second equation to find x and plug it in in terms of y
10 = x + y
X = 10 - y
2) plus it into first equation
122= 14(10 - y) + 8y
122 = 140 - 14y + 8y
