U estimate that there are 40 marbles in a jar the actual amount is 48 marbles find the percent error round to the nearest 10th of a percent

Answers

Answer: 10.7%

Step-by-step explanation:

The percentage error will be calculated as:

Estimated value - Actual value / Actual value × 100

= (40 - 48) / 48 × 100

= 8/48 × 100

= 1/6 × 100

= 10.7%

Tan(x) *cos(x)*cos(x)= ( the answer should have sin only ) ASAP

Answers

This doesn't make any sense because you didn't give a value to cos like you did to sin.

Let me guess the actual question is tan(x)*cos(x) write this in term of sin.

Now from trigonometry identities, we know that tan(x)=sin(x)/cos(x)

So the expression can be written as sin(x)/cos(x)*cos(x)

which results in sin(x) as the answer, if I guessed the question wrong, sorry and please tell me in the comments what the correct question is, because this question doesn't seem complete :)

Select all of the following that are true. *
sinA=18/30
sinA=3/5
cosA=10/6
cosA=8/10
cosA=5/3
tanF=24/18
tanF=3/4
tanD=3/4
sinD=18/30

Answers

Answer:

Step-by-step explanation:

sin A = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{6}{10}[/tex] = [tex]\frac{3}{5}[/tex]

cos A = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{8}{10}[/tex] = [tex]\frac{4}{5}[/tex]

tan F = [tex]\frac{DE}{FE}[/tex] = [tex]\frac{24}{18}[/tex] = [tex]\frac{4}{3}[/tex]

tan D = [tex]\frac{FE}{DE}[/tex] = [tex]\frac{18}{24}[/tex] = [tex]\frac{3}{4}[/tex]

sin D = [tex]\frac{FE}{FD}[/tex] = [tex]\frac{18}{30}[/tex] = [tex]\frac{3}{5}[/tex]

I need an explanation for the problem 4v2=-12v-9. I don't understand why it factors into 4v+3 and 4v+3

Answers

Answer:

The factors are [tex]2v+3,2v+3[/tex].

The factors are not [tex]4v+3,4v+3[/tex]

Step-by-step explanation:

Equation is [tex]4v^2=-12v-9[/tex].

This equation can be written as follows:

[tex]4v^2+12v+9=0[/tex]

Here,

[tex]12v=6v+6v[/tex]

Therefore,

[tex]4v^2+6v+6v+9=0\\2v(2v+3)+3(2v+3)=0\\(2v+3)(2v+3)=0[/tex]

So, the factors are [tex]2v+3,2v+3[/tex].

The factors are not [tex]4v+3,4v+3[/tex]

Jean needs 2 gallons of olive oil to make a recipe. If the olive oil 8:00 a quart how much money will she need to buy the olive oil

Answers

Answer:

$64

Step-by-step explanation:

Given that :

Required amount of olive oil = 2 gallons

Cost per quartz = $8

Recall:

1 quartz = 0.25 gallons

Amount of quartz in 2 gallons :

2 / 0.25 = 8 quartz

Cost of olive oil needed :

8 quartz * $8

= $64

A program was created to randomly choose customers at a shoe store to receive a discount. The program claims 15% of the receipts will get a discount in the long run. The manager of the shoe store is skeptical and believes the program's calculations are incorrect. She selects a random sample and finds that 12% received the discount. The confidence interval is 0.12 ± 0.05 with all conditions for inference met.


Part A: Using the given confidence interval, is it statistically evident that the program is not working? Explain.


Part B: Is it statistically evident from the confidence interval that the program creates the discount with a 0.15 probability? Explain.


Part C: Another random sample of receipts is taken. This sample is six times the size of the original. Twelve percent of the receipts in the second sample received the discount. What is the value of margin of error based on the second sample with the same confidence level as the original interval?


Part D: Using the margin of error from the second sample in part C, is the program working as planned? Explain.

Answers

Answer:

A: There is no statistical evidence that the program is not working as intended because 0.15 is between the range of 0.12 ± 0.05 = (0.07,0.17)

B: 0.15 is between the range of (0.07,0.17) so it is statistically probable.

C: margin of error=0.05/((6)^(1/2))=0.0204

D: No the program is not working as planned because 0.15 is not within the range of 0.12±0.0204=(0.0996,0.1404)

Answer:

  PR = 8

Step-by-step explanation:

The median bisects the side opposite the vertex, so ...

  P is the midpoint of AC

Since AC = 25, the length of half that segment is PC = 12.5. Of course, that is the sum of segments PR and RC:

Answers

Answer:

3x - 1 = 0

Step-by-step explanation:

If x = 1/3

multiply both sides by 3

3 * x = 1/3 * 3

3x = 1

Subtract 1 from both sides ;

3x - 1 = 1 - 1

3x - 1 = 0 ( the factor which gives the solution)

3x - 1 = 0

3x = 1

Doavide both sides by 3

3x / 3 = 1/3

x = 1/ 3

Answers

Answer:

-8, -8

Step-by-step explanation:

If you add the equations, you get -7x + 4x + 4y - 4y = 24. Canceling out the 4y and the -4y, and adding 4x to -7x, you get -3x = 24. Divide both sides by -3 and you get x = -8. Next, pick an equation and substitute x for -8. I am going to use the first equation. (-7)-8 + 4y = 24 is equal to 56 + 4y = 24. Subtract 56 from both sides to get 4y is equal to -32, and if you divide both sides by 4, you get y = -8.

9514 1404 393

Answer:

  (-8, -8)

Step-by-step explanation:

We notice that the coefficients of y are +4 and -4, so have a sum of zero. This means we can add the two equations to eliminate the y-terms.

  (-7x +4y) +(4x -4y) = (24) +(0)

  -3x = 24 . . . . . . . . . simplify

  x = -8 . . . . . . . . . . . divide both sides by -3

Now, we can find y using either equation.

  4(-8) -4y = 0

  -8 -y = 0 . . . . . . . . divide both sides by 4

  -8 = y . . . . . . . . . . add y to both sides

The solution to the system of equations is ...

  (x, y) = (-8, -8)
