Answer:

$150 each month

Step-by-step explanation:

divide 300 in half because they contribute 50¢ per dollar

The equivalent fractions will be 12/30 and 25/30

Given the fraction 2/5 and 5/6

To make them the same, we will multiply the value of 5 by 6 and the value of 6 by 5

For the deniminator of 5, the equivalent denominator is (5*6) = 30

For the denominator of 6, the equivalent denominator is (6*5) = 30

Equivalent fraction for 2/5 = 2/5 * 6/6

Equivalent fraction for 5/6 = 5/6 * 5/5

Hence the equivalent fractions will be 12/30 and 25/30

Answer:

0.6887

Step-by-step explanation:

Using normal distribution, the probability of that mean distance from the center of the target for Tory is more than for Adam is 0.6887.

Normal distribution is "continuous probability distribution that its symmetrical around its mean with most values near the central peak".

According to the question,

Tory's distances from the center of the target are normally distributed with a mean of 123mm and a standard deviation 31mm. Number of attempts for Tory is 5.

Adam's  distances from the center of the target are with a mean of 108mm and a standard deviation 47mm. Number of attempts for Adam is 3.

In order to find the probability of that mean distance from the center of the target for Tory is more than for Adam.

Normal distribution z =   (x-μ)/σ       x ~ (μ,σ)

When x = 108

z = (123 - 108)/47  [Adam's  distances from the center of the target are normally distributed with a mean of 108mm and a standard deviation of Adam is 31mm.]

= 0.3191

P(x > 108) = P(z > - 0.3191)

                = 1 - 0.3191   [since the probability of the normal curve is 1 and to find the area under tory mean is greater than the Adam mean only if we subtract 1 from z value]

                = 0.6887

Hence, Using normal distribution, the probability of that mean distance from the center of the target for Tory is more than for Adam is 0.6887.

Multiply both sides by 4

[tex]4 \times \frac{3}{4} x = 4 \times 36 \\ [/tex]

[tex]3x = 144[/tex]

Divide both sides by 3

i. Limit[(t^3 + 3t^2 - 12t + 4)/(t^3 - 4t), t -> 2]

ii. For a one-sided limit, is the Direction option.

Limit[(y + 6)/(y^2 - 36), y -> 6, Direction -> -1]

The option value -1 essentially means we treat y as if it's greater than 6, so its value has to decrease in order to approach 6.

The answer is sides are congruent by the reflexive property

Step-by-step explanation:

The answer is sides are congruent by the reflexive property because the two red lines on the triangles represnt that they are congruent. The reason teh fourth one can be a correct answer, but it is not, is because the angles are not vertical. The angles would hav eto be in teh middle of the triangle and congruent, to be right. So it is a reflexive property.

Answer:

The nth term of the sequence is -5n + 2 (or 2 - 5n)

Answer:

[tex]a_{n}[/tex] = - 5n + 2

Step-by-step explanation:

There is a common difference between consecutive terms , that is

- 13 - (- 8) = - 18 - (- 13) = - 5

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3 and d = - 5 , then

[tex]a_{n}[/tex] = - 3 - 5(n - 1) = - 3 - 5n + 5 = - 5n + 2

Answer:

D. erosion

Step-by-step explanation:

The wind is a stronger erosional force in arid regions than it is in humid regions because winds are stronger. In humid areas, water and vegetation bind the soil so it is harder to pick up. In arid regions, small particles are selectively picked up and transported. As they are removed, the ground surface gets lower and rockier, causing deflation. What is left is desert pavement, a surface covered by gravel-sized particles that are not easily moved by wind.

Answer:

y = -1/4x + 2

Step-by-step explanation:

1. First you find m. Because the line is slanting downwards, you know it is negative. Then you can find the number by looking at the rise over run (rise/run). We can go up 1 (rise) and then to the side 4 (run). We go to the right side 4 because that is where the line intersects with up 1. So because the rise goes over the run, the number would be 1/4. But remember that it is negative so m = -1/4

2. Now we have to find c. For this you just have to go up or down the y-axis until you find the point where it intersects with the line. On this graph it intersects on positive 2. So c = + 2

Step-by-step explanation:

q is inversely to p and we need to add k as the constant..

then find value of k by sub the value of p and q

after that sub the value of k and p to find q

  (x, y, z) = (2, -4, 3)

Step-by-step explanation:

It is convenient to let an appropriate calculator reduce the augmented matrix to reduced row-echelon form. The rightmost column in that form is the solution vector [x, y, z].

__

If you want to solve this by hand, you can perform the following row operations to reduce the augmented matrix as shown in the attachment.

r1 ← r2 +r3; r2 ← (r2 +r3)/7 . . . . use this matrix for the next row replacement

r3 ← (r3 -r1 -4·r2)/11 . . . . . . . . . . use this matrix for the next row replacement

r1 ← r1 -2·r2 +5·r3

__

r1, r2, r3 refer to rows 1, 2, 3, respectively. The indicated multiplication and division are scalar operations, operating on each individual term in the row.

Additional comment

Most graphing calculators have matrix solving functions. Apps are available for phone and tablet that will do this, and there are online websites that will reduce an augmented matrix as well.
