Ariah has $141.25 in her savings account. She deposits $15 every week. Her mother also deposits $25 into the account every time Ariah does cares for her younger sibling for the day. Her savings account balance can be shown with the following expression: 25c + 15w + 141.25 If Ariah saves for 8 weeks and cares for her younger siblings 16 times, how much will she have in her account?

Answer:

L = \(\frac{P - 12}{2}\)

Step-by-step explanation:

Since perimeter is 2L + 2W, and width is 6, then P = 2L + 2*6, and solving for L gives you (P - 12)/2

The probability of picking a red ball is 2/3.

As given in the student question,

The probability that a randomly selected person would be a protestant and at the same time be a democrat or a republican is not given in the problem statement.

Hence, it cannot be determined without further information.

Probability is the branch of mathematics that deals with the study of uncertainty.

It provides a framework for analyzing random events that occur in the real world.

Probability helps us to estimate the likelihood of a particular event occurring. It helps us to make informed decisions when faced with uncertain outcomes.

It plays a critical role in many fields such as science, engineering, economics, and finance.

Probability formula:

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes.

The formula for probability is given by:

P (A) = Number of favorable outcomes/ Total number of outcomes

where P (A) represents the probability of event A.

Example:

Suppose we have a bag containing 10 red balls and 5 blue balls.

The total number of outcomes = 10 + 5 = 15

The number of favorable outcomes = 10P (Red ball) = 10/15 = 2/3

Therefore, the probability of picking a red ball is 2/3.

Answer:

x = 5

Step-by-step explanation:

This uses the altitude on hypotenuse theorem

The 2 triangles formed are similar to the given triangle and to each other.

Δ ADB ~ Δ BDC

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\(\frac{DB}{DC}\) = \(\frac{AD}{BD}\) , substitute values

\(\frac{10}{4x}\) = \(\frac{x}{10}\) ( cross- multiply )

4x² = 100 ( divide both sides by 4 )

x² = 25 ( take the square root of both sides )

x = \(\sqrt{25}\) = 5

Answer:

false, it's the opposite so its doesn't have the same amount, negative or positive.

True.

The absolute value of opposite numbers is the same as the number because the absolute value is always positive.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number = x

The opposite of x is -x.

The correct answer is:

(a) about 4% of the variation in y has been explained by the model.

The answer is (a) about 4% of the variation in y has been explained by the model.

The coefficient of determination (R-squared) is given as 0.03579295, which represents the proportion of the total variation in the dependent variable (calculus achievement scores) that is explained by the independent variable (algebra placement test scores) in the model.

Since R-squared is the square of the correlation coefficient (multiple R), we can also interpret the value of multiple R as the correlation between the two variables. In this case, multiple R is given as 0.18919025, indicating a weak positive correlation between the two variables.

The adjusted R-squared is negative (-0.2856094), which suggests that the model is not a good fit for the data. However, the question specifically asks for the proportion of variation in the dependent variable that is explained by the model, which is represented by R-squared. Therefore, the answer is (a) about 4% of the variation in y has been explained by the model.

When a boulder is pushed off a cliff, the potential energy of the boulder will be at its maximum just before it starts to fall and at its minimum just as it hits the ground.The potential energy of the boulder is at its maximum just before it starts to fall because it is at its highest point and has not yet begun to move.

The potential energy of an object is determined by its location relative to other objects and the conditions that surround it. When a boulder is pushed off a cliff, the energy stored in it is converted from potential energy to kinetic energy.

Therefore, when a boulder is pushed off a cliff, the potential energy of the boulder will be at its maximum just before it starts to fall and at its minimum just as it hits the ground.The potential energy of the boulder is at its maximum just before it starts to fall because it is at its highest point and has not yet begun to move.

At this point, the boulder has stored the maximum amount of energy that can be converted into kinetic energy when it starts to fall. At this point, the potential energy is equal to the gravitational potential energy (GPE) of the boulder, which is given by the equation GPE = mgh, where m is the mass of the boulder, g is the acceleration due to gravity, and h is the height of the cliff.The potential energy of the boulder is at its minimum just as it hits the ground because it has no more height to lose.

At this point, all of the potential energy that the boulder had at the top of the cliff has been converted into kinetic energy as it fell, and this kinetic energy has been transferred to other objects as the boulder collided with them. Therefore, the potential energy of the boulder is zero at this point.

g(x) = (x - 7)² - 3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

I ⊆ I' if and only if a' ≤ a and b ≤ b'. This relationship holds true for closed intervals I and I' in R. To show that I ⊆ I' if and only if a' ≤ a and b ≤ b', we will consider two cases:

1. If I ⊆ I', then for any x ∈ I, we have x ∈ I'. Since I and I' are closed intervals, we can write them as I = [a, b] and I' = [a', b']. We want to show that a' ≤ a and b ≤ b' in this case.

Since x ∈ I, we know that a ≤ x ≤ b. Now, since x also belongs to I', we have a' ≤ x ≤ b'. Since this is true for any x in I, we can conclude that a' ≤ a and b ≤ b'.

2. If a' ≤ a and b ≤ b', we want to show that I ⊆ I'. Let x be any element in I, so we have a ≤ x ≤ b. We are given that a' ≤ a and b ≤ b'. Since a' ≤ a and a ≤ x, we can infer that a' ≤ x. Similarly, since x ≤ b and b ≤ b', we can infer that x ≤ b'. Therefore, x ∈ I'.

Since x was an arbitrary element in I, we can conclude that I ⊆ I' when a' ≤ a and b ≤ b'.

In summary, I ⊆ I' if and only if a' ≤ a and b ≤ b'. This relationship holds true for closed intervals I and I' in R.

So, Lana gave away 26.32% of he Pokemon cards  to her little brother.

To find the percentage of cards Lana gave away, we can use the formula:(Quantity given away / Total quantity) * 100.

In this case, Lana gave away 125 cards out of her total collection of 475 cards.Plugging these values into the formula, we have:

(125 / 475) * 100 = 0.2632 * 100 = 26.32%.

Lana gave away 26.32% of her Pokemon cards to her little brother.

Alternatively, we can calculate the percentage by subtracting the remaining cards from the total and finding the ratio:

Percentage given away

= (Cards given away / Total cards) * 100

The equation of the circle, obtained by applying the completing the square method to the specified equation indicates that the center and radius of the circle are;

Center (0, 6) and radius 7.5

The general form of the equation of a circle is; (x - h)² + (y - k)² = r², where;

(h, k) = The coordinates of the center of the circle

r = The measure of the length of the radius

The possible equation obtained from a similar question on the internet can be presented as follows;

x² + y² - 12·y - 20.25 = 0

The above equation can be evaluated using the completing the square method and excluding the x² term as follows;

y² - 12·y - 20.25 = 0

y² - 12·y = 20.25

y² - 12·y + (-12/2)² = 20.25 + (-12/2)²

y² - 12·y + (-6)² = 20.25 + (-6)² = 56.25

(y - 6)² = 56.25

Therefore;

y - 6 = √(56.25) = ±7.5

The possible equation of the circle obtained by plugging in the x² term therefore is; (x - 0)² + (y - 6)² = 7.5²

The center of the circle is therefore;

(h, k) = (0, 6)

The radius of the circle, r = 7.5

Answer:

B) 56

Step-by-step explanation:

There are 16 ounces in 1 pound, so first you must convert the 28 pounds to ounces. You do this by multiplying 28 and 16.

28 × 16 = 448

Next, divide 448 by 8 to find out how many servings there are.

448 ÷ 8 = 56

Answer:

y = 7x - 16:

Slope = 14.000/2.000 = 7.000

 x-intercept = 16/7 = 2.28571

 y-intercept = -16/1 = -16.00000

y = 2(2x - 5)=

Slope = 8.000/2.000 = 4.000

 x-intercept = 10/4 = 5/2 = 2.50000

 y-intercept = -10/1 = -10.00000
