Percent Error Exact value Approximate value 32 Error Ratio Item Baseball caps Percent error Absolute error 3 29 3 3 (100) 29 ( 3 0 32 (100) O 32 3 29​

Answers

Answer:

Your answer is A.

Step-by-step explanation:

The expression that finds the percent error is (3 / 32) * 100.

Option B is the correct answer.

We have,

To find the percent error in this situation, we can use the following expression:

Percent Error = (|Predicted Value - Actual Value| / Predicted Value) * 100

In this case, the predicted value is 32 baseball caps, and the actual value is 29 baseball caps.

Plugging these values into the expression, we get:

Percent Error = (|32 - 29| / 32) * 100

Simplifying further:

Percent Error = (3 / 32) * 100

Thus,

The expression that finds the percent error is (3 / 32) * 100.

If a grocery store is selling 3 oranges for $1.47 .What is the unit cost ?

Answers

Answer:  0.49 dollars, which is equivalent to 49 cents

==========================================================

Work Shown:

Divide the total cost over the number of items to get the unit cost

unit cost = (total cost)/(number of items)

unit cost = (1.47)/(3)

unit cost = 0.49 dollars

unit cost = 49 cents

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

Another approach:

3 oranges = 1.47 dollars

3/3 oranges = 1.47/3 dollars

1 orange = 0.49 dollars

1 orange = 49 cents

The unit cost is the cost of 1 item, so the the unit cost is 49 cents per orange.

Helpppp someone pleaseee

Answers

Answer:

1. the given angle is supplementary to <1, so we can create an equation x + 75 = 180, where x is <1. We can solve this to get 105

3. <3 is vertical to <1, so they have the same value, this means that it is also 105

4. <4 is vertical to <2, angle to is given as 75, so <4 is also 75

5. <5 is corresponding to <1, so this means that they are in the relatively same spot. This means that the values are the same, so <5 is also 105

6. <6 corresponds to <2, this means they also have the same value so <6 is also 75

7.  <7 is vertical to <5, and we know <5 is 105, so <7 is also 105

8. <8 corresponds to <4, we know that <4 is 75, so <8 is also 74

Answer:

1 = 105°

2 = 75°

3 = 105°

4 = 75°

5 = 105°

6 = 75°

7 = 105°

8 = 75°

Step-by-step explanation:

2, 4, 6, 8 are going to be the same

1, 3, 5, 7 are going to be the same

If 2 = 75, then 4, 6, and 8 are too

So, there is 360° in one circle right? Yes, so, we can see that 2 = 4 and we do not know 1 nor 3 but we do know that 1 = 3. So, 1 + 2 + 3 + 4 = 360

2x + 75 x 2 = 360

2x + 150 = 360

2x = 360 - 150

2x = 210

x = 105

1 = 105°

2 = 75°

3 = 105°

4 = 75°

5 = 105°

6 = 75°

7 = 105°

8 = 75°

Four-quadrant Cartesian graph with integer tickmarks from -9 to 9 (or -10 to 10) for x and y axes, with a straight line with arrowheads drawn through two points labeled A and B. Point A is at (-2,- 1) and point B is at (6,5).

Answers

Answer:

y -5 = (3/4)(x -6)

Step-by-step explanation:

Between the two points, the line has a rise of 6 and a run of 8. Thus, the slope is ...

... m = rise/run = 6/8 = 3/4

The point-slope form of the equation of a line with slope m through point (h, k) is ...

... y - k = m(x - h)

For point B, (h, k) = (6, 5), so filling in the values gives ...

... y - 5 = (3/4)(x - 6)

If a fair die is rolled 3 times, what is the probability, to the nearest thousandth, of getting exactly 2 fives?

Answers

Answer:

The answer is .578 you just do 5/6 due to the fact that there are 6 sides on a die and 1 side is a 2 so if you don’t get a two there is 5 sides left so you do 5/6 to the power of 3 leaving you with .578 and some

Step-by-step explanation:

The probability of getting exactly 2 fives in 3 rolls of a fair die is approximately 0.0694.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

The probability of getting a five on a single roll of a fair die is 1/6. The probability of not getting a five on a single roll is 5/6.

To find the probability of getting exactly 2 fives in 3 rolls, we can use the binomial probability formula:

[tex]P(X = k) = ^nC_{k} p^k(1-p)^n^-^k[/tex]

Where  n is the number of trials, n= 3

k is the number of successes we want, k=2

p is the probability of success on a single trial (1/6)

Plugging in the values, we get:

[tex]P(X = 2) = ^3C_{2}.(1/6)^2(5/6)^(^3^-^2^)[/tex]

= 3. (1/6)²(5/6)

= 0.0694

Therefore, the probability of getting exactly 2 fives in 3 rolls of a fair die is approximately 0.0694
