good morning everyone how are you guys

i just want to say today is my science exam
soo if u helped me

that will be nice <3

Answer:

I'm pretty sure it's C.

Step-by-step explanation:

Answer:

If x=0 then the answer is 20.

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

6x0 = 0 so 20 plus 0 = 20 when x = 0 because x cancels out

Answer:

The slope of the line that is perpendicular is 3/8

Step-by-step explanation:

The slope of the line through

(-6,4) (10,-2)

m = ( y2-y1)/(x2-x1)

    = ( 10 - -6)/( -2 -4)

    = (10+6)/(-2-4)

     = 16/-6

    =-8/3

A line perpendicular has a slope that is the negative reciprocal

- 1/( -8/3)

+ 3/8

The slope of the line that is perpendicular is 3/8

Answer:

D) 13 1/8

Step-by-step explanation:

105/8=13 1/8 cups

Hope this helped! :)

Answer:

the answer is 55% are satisfied with the car

Answer:

1. Yolanda's error is that the sample does not consist of all of Tichenor Middle School's students.

2. The sample size is 40 students. This is the sample size, because if you add up the amounts of students which voted for each animal, it adds up to 40.

Answer:

a)x₁  = 24  business owners plan to provide a gift this year

b)  p-value = 0,0017

c)p-value < α   we have to eject H₀   And support the claim that the proportion of business owners providing gifts has decrease

Step-by-step explanation:

a) Sample size 80

proportion  p₁  = 30 %   p₁ = 0,3

Then   x₁ = 80*0,3

x₁  = 24  business owners plan to provide a gift this year

b) Hypothesis Test

Null Hypothesis                    H₀          p₁  =  0,45

Alternative Hypothesis        Hₐ          p₁  <  0,45

p₁  =  0,3   then  q₁  =  1  -  0,3    q₁ =  0,7

z(s)  = ( p₁  -  0,45 )/ √p₁* q₁ / n

z(s)  =  -  0,15 / √0,002625

z(s) = - 0,15 / 0,05123

z(s) = - 2,9279

b)From z-table we find  p-value = 0,0017

c) If  α = 0,05   ( significance level )  as

p-value < α   we have to eject H₀   And support the claim that the proportion of business owners providing gifts has decrease

Answer:

5/51 or 9.8

Step-by-step explanation:

Since she does not put the marble back it's dependent.

1/3 chances the first marble is red and 5/17 the second is too.

Multiply and you get 5/51 odds, or approximately 9.8% chance

Answer:

1/9.

Step-by-step explanation:

Prob(First marble is red) = 6/18 = 1/3

Prob(Second marble is red) = 1/3

Required probability = 1/3 * 1/3 = 1/9.

Answer:

100

Step-by-step explanation:

Answer:

the answer is 62.8cm^2

Step-by-step explanation:

4•3.14•5

By using the formula for the surface area of the sphere [tex]S.A = 4 \pi r^2[/tex], the surface area of this sphere would be, [tex]S.A = 314[/tex] cm²

Used the formula of the surface area of the sphere,

[tex]S.A = 4 \pi r^2[/tex]

Where 'r' is the radius of the sphere.

Given that,

Diameter of a sphere = 10 cm

We know that the radius of the sphere is half of the diameter of the sphere.

Hence, the radius of the sphere is,

[tex]r = \dfrac{10}{2}[/tex]

[tex]r = 5[/tex] cm

Substitute r = 5 cm in the above formula,

[tex]S.A = 4 \pi r^2[/tex]

[tex]S.A = 4 \times 3.14 \times 5^2[/tex]

Therefore, the surface area of a sphere is,

[tex]S.A = 314[/tex] cm²

Answer:

B. The sample selected from one of the populations has no effect or bearing on the sample selected from the other population.

Step-by-step explanation:

In statistical analysis, the use of independent samples for diverse studies is common.

Independent samples are such that the sample selected from one of the populations has no effect or bearing on the sample selected from the other population.

This means that samples are selected randomly in such a way that an observation obtained from a sample does not depend on the values obtained from the observation of another sample from the other population.

Answer:

1) c. 10

2) a. 1 and 18

3) d. 17

4) I think it's actually 12 but I don't know

Answer:

8,25

Step-by-step explanation:

Answer:

{13.7756,18.2244}

Step-by-step explanation:

Given the sample size, the margin of error can be calculated with the formula [tex]M=Z*\frac{\sigma}{\sqrt{n}}[/tex] where Z is the critical value for the desired confidence level, σ is the population standard deviation, and n is the sample size. Therefore, our margin of error for a 90% confidence level is:

[tex]M=Z*\frac{\sigma}{\sqrt{n}}=1.645*(\frac{8}{\sqrt{35}})=2.2244[/tex]

The formula for a confidence interval is [tex]CI=\bar{x}+M[/tex] where x-bar is the sample mean. Therefore, the 90% confidence interval for the mean amount of sushi pieces a person can eat is:

[tex]CI=\bar{x}\pm[M]=16\pm2.2244={13.7756,18.2244}[/tex]

Therefore, we are 90% confident that the true mean amount of sushi pieces a person can eat is contained within the interval {13.7756,18.2244}

Answer:

[tex]57\frac{3}{11}[/tex] = c

or

[tex]57.\overline{27}[/tex] = c

Step-by-step explanation:

We know that the diameter of a circle multiplied by [tex]\pi[/tex] is the circumference, so we can create this equation:

180 = c * [tex]\pi[/tex]

Your teacher told us to assume [tex]\pi[/tex] is 22/7, so we'll put that in

180 = c * [tex]\frac{22}{7\\}[/tex]

To get c by itself, we divide both sides by 22/7

[tex]\frac{180}{\frac{22}{7}}[/tex] = c

Dividing by a number is the same as multiplying by its reciprocal, so we'll multiply 180 by 7/22

180 * [tex]\frac{7}{22}[/tex] = c

Evaluate

[tex]\frac{1260}{22}[/tex] = c

[tex]57\frac{3}{11}[/tex] = c

If you want a decimal instead:

[tex]57.\overline{27}[/tex] = c

Answer: 640-720

Step-by-step explanation:

Answer:

1. college

2, salary

3. true experiment

4. 2

Step-by-step explanation:

1. in this scenario the independent variable is the college. that is  either walton college or non walton.

2. the dependent variable is the variable of interest. And this is salary. Students want to know what to major in that can give them a lot of salary when they start working.

3. This is a true experiment due to the random sample assigned.

4.  2 conditions to infer causation have been met.

Answer:

The answer is 0.25

Step-by-step explanation:

Answer:

a) t = 2.2010

b) t = 1.7291

c) t = 3.4995.

Step-by-step explanation:

a. The sample size is 12 and the level of confidence is 95%.

12 - 1 = 11 degrees of freedom, either two-tailed test at [tex]\alpha = 0.975[/tex] or one-tailed test at [tex]\alpha = 0.95[/tex], so t = 2.2010.

b. The sample size is 20 and the level of confidence is 90%.

20 - 1 = 19 degrees of freedom, either two-tailed test at [tex]\alpha = 0.95[/tex] or one-tailed test at [tex]\alpha = 0.9[/tex], so t = 1.7291.

c. The sample size is 8 and the level of confidence is 99%.

8 - 1 = 7 degrees of freedom, either two-tailed test at [tex]\alpha = 0.995[/tex] or one-tailed test at [tex]\alpha = 0.99[/tex], so t = 3.4995.

Answer:

I would go with third one down     3 1/2

Step-by-step explanation:

2 1/3 × 1 1/2

7/3 × 3/2   =  (7×3)/(3×2)

                 = 21/6

                 = 3 3/6

                 = 3 1/2

Answer: y = 12x + 5

Step-by-step explanation:

Since the going rate is $12/hr, that will be the x coefficient. Since the starting fee is $5, that will be the y-intercept.
