What does 3,18 mean?

The number 3 indicates the value in x, while the number 18 indicates the value of y.

x = 3 weeks (time)

y = 18 ounces (weight)

What statements are true about this graph?

It is true the rate was 6 ounces per week (18 ounces/6 = 3).

It is true by the end of week 3 the weight was 18 ounces.

The midpoint of any segment is exactly in the middle, which splits our segment into two equal halves

In our problem,

E is the midpoint

DE = x + 5

FE = 3x - 7

FE = DE

Let's solve for x

3x - 7 = x + 5

Subtract x from both sides and add 7 to both sides.

2x = 12

Divide both sides by 2

x = 6

Let's plug this into DE.

DE = x + 5 = 6 + 5 = 11

Answer: Choice E) Insufficient information to prove congruence.

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

Explanation:

We're given that AB = DC and BE = CE. This means we have two pairs of congruent sides and we could use SAS if we know that angle ABE = angle DCE. However, we don't know this information.

While we do know that angle AEB = angle DEC (vertical angle theorem), this is not enough information. Recall that SSA is not a valid congruence theorem. The angles in question are not between the sides mentioned in the previous paragraph.

Therefore, we don't have enough information to prove the triangles congruent.

Answer:

1/2

Step-by-step explanation:

Reduce 12/24 to lowest terms

Find the GCD (or HCF) of numerator and denominator. GCD of 12 and 24 is 12.

12 ÷ 1224 ÷ 12.

Reduced fraction: 12. Therefore, 12/24 simplified to lowest terms is 1/2.

Answer: (2, -1)

Step-by-step explanation:

To determine if an ordered pair is a solution to an inequality, we substitute the values of x and y into the inequality and see if the resulting expression is true or false.

A. For (7,2), we have:3(7) + 4(2) = 21 + 8 = 29 29 > 5, so (7,2) is not a solution to the inequality.

B. For (2,-1), we have:3(2) + 4(-1) = 6 - 4 = 2 2 ≤ 5, so (2,-1) is a solution to the inequality.

C. For (5,-1), we have:3(5) + 4(-1) = 15 - 4 = 11 11 > 5, so (5,-1) is not a solution to the inequality.

D. For (6,1), we have:3(6) + 4(1) = 18 + 4 = 22 22 > 5, so (6,1) is not a solution to the inequality.

So, the ordered pair that is a solution to the inequality is (2,-1).

Answer:

  (0, -6), (1, -2), (2, 2), (3, 6)

Step-by-step explanation:

A solution to the given equation will be an (x, y) pair that satisfies the equation. There are an infinite number of possibilities.

It is generally convenient to find a solution by rewriting the equation so one variable can be found in terms of the other. Here, the coefficient of y is -1, so it is convenient to solve the equation for y:

  4x -y = 6

  4x -6 = y . . . . . . add y-6 to both sides

  y = 4x -6 . . . . . . write with y on the left

This lets us choose any value we like for x, and find the corresponding value of y. We generally prefer small integers, but any value can be chosen. For example, for x=0, we have ...

  y = 4(0) -6 = -6

and the corresponding ordered pair is (x, y) = (0, -6).

The attachment shows other (x, y) pairs to be ...

  (1, -2), (2, 2), (3, 6)

Answer:

Step-by-step explanation:

The meaning of the translation (x + 6, y + 10) is that all points in a coordinate plane are moved 6 units to the right and 10 units up.

In other words, for any point (x, y) in the original position, after the translation, the new coordinates would be (x + 6, y + 10). This means that the x-coordinate of each point is increased by 6 units, resulting in a shift to the right, and the y-coordinate is increased by 10 units, resulting in a shift upwards.

Answer:

Slope: \(\frac{4}{1}\)

Y - intercept: -1

Step-by-step explanation:

We can see from the graph that the slope is \(\frac{4}{1}\).

We can also identify the y - intercept as -1.

Therefore, the linear equation would be y = \(\frac{4}{1}\)x -1

Answer:

2 : 4 : 1

Step-by-step explanation:

First take common factors by factorization.

56 = 14 x 4 = 28 x 2

112 = 14 x 8 = 28 x 4

28 = 14 x 2 = 28 x 1

Remove the 28 common factor.

Therefore,

56 : 112 : 28

= 2 : 4 : 1

Since, Alice ate 5 cookies and 2 carrots for a total of 590 calories; bob ate 3 cookies and 4 carrots for a total of 410 calories. Therefore, In a cookie there are 110 calories.

A calorie is a unit of energy that food and drink provide. we can usually find out how many calories are listed in foods, and wearables like the best fitness trackers let you monitor how many calories you're burning in different activities. Certain foods, such as processed foods, tend to be high in calories. Other foods, such as fresh fruits and vegetables, tend to be low in calories. there is not. Calories are needed to give you enough energy to move, keep warm, grow, work, think, and play. Our circulation and digestion also need to work well with the energy we get from calories.

Let x = calories in cookies.

     y = calories in carrots.

Now, according to the question:

     5x + 2y = 590                   --------------------------------------- (1)

     3x + 4y = 410                    -------------------------------------- (2)

Multiplying equation(1) by 3 and equation(2) by 5:

         15x + 6y = 1770                       ---------------------------(3)

         15x + 20y = 2050                   ---------------------------(4)

Solving we get:

    y = 280/14

or, y = 20 units.

Putting the value of y = 20 in equation (2)

    3x + 4y = 410

⇒  3x + 4 × 20 = 410

⇒ 3x = 410 - 80

⇒ x = 330/3

⇒ x = 110 Units

Therefore, the calories of cookies is 110 units .

4.0 mL of marcaine will be needed to draw up to equal the 1%.

Marcaine is a brand name for the medication bupivacaine, which is a local anesthetic used to numb a specific area of the body during a surgical or medical procedure.

To determine the amount of marcaine that is needed to be drawn up to equal the 1% lidocaine, we can use the following formula:

(Concentration of Lidocaine) / (Concentration of Marcaine) = (Volume of Lidocaine) / (Volume of Marcaine)

In this case, we know that the concentration of lidocaine is 1% and the concentration of marcaine is 0.25%. So we can plug these values into the formula:

1 / 0.25 = (Volume of Lidocaine) / (Volume of Marcaine)

To solve for the volume of marcaine, we can multiply both sides of the equation by the volume of lidocaine:

(Volume of Lidocaine) / (Volume of Marcaine) = 4

Therefore, 4.0 mL of marcaine will be needed to draw up to equal the 1%.

The likelihood that a data is within two standard deviations of the mean

By observation, the distribution depicted in the task content above is a normal distribution.

One can tell the difference between the following .

In the case of a standard normal distribution, 68% of the observations (datum) are within one standard deviation of the mean, 95% are within two standard deviations of the mean, and 99.9% are within three standard deviations of the mean.

Answer:

0.2 = n

Step-by-step explanation:

Since we want to express 3:15 as n:1, we can say that they are equal ratios, so

3:15 = n:1. Next, ratios can be written as fractions, so 3/15 = n/1 .

3/15 = n/1

Since anything divided by 1 equals itself, we can write this as

3/15 = n

0.2 = n
