Answer:

-41.79

Madeline was overdrawn $41.79.

Step-by-step explanation:

If she deposited $29.06 a week for 8 weeks, she put

8 × 29.06

= 232.48

$232.48 into her account. But they're saying she now has only $190.69. Some of the money went to payback the negative balance she had.

Balance+232.48=190.69

Balance=190.69-232.48

Balance = -41.79

Madeline had a negative balance of $41.79.

The required value of the expression (2x − 12) + (1/2 xy - 10) for x = 8 and y = 2 is 2. Option D is correct.

First, let us understand the algebraic expression and how is it formed:

A multitude of strategies is used to build algebraic expressions utilizing variables and constants. It is a term-based mathematical expression that comprises variables, constants, and algebraic operations such as addition, subtraction, and so on.

We are given:

(2x − 12) + (1/2 xy - 10)

We need to find the value of the given expression for x = 8 and y = 2.

Substitute the values of x and y in the given expression, we will get;

(2 * 8 − 12) + (1/2 * 8 * 2 - 10)

= (16 − 12) + (8 - 10)

= 4 + (-2)

= 4 - 2

= 2

So, the obtained value is 2.

Thus, the required value of the expression (2x − 12) + (1/2 xy - 10) for x = 8 and y = 2 is 2. Option D is correct.

The probability that at least one of the cards drawn is a 3 is 1/5 0r 0.2000.

What is probability?

Probability shows the likelihood of an event happening.  It can be calculated by dividing the number of outcomes of an event by the total number of possible outcomes or sample space. Probability is equal to '1' when the event is certain to occur. i.e P =1. It is less than '1' when it is not likely to occur. i.e P< 1

Probability P=no. outcomes/total no. of the possible outcomes

From the question;

No. of total no of cards =5

The probability the card drawn is a 3  =1/5

                                                             =0.2000

In the question ,

it is given that ,

the Volume of the rectangular prism is = x³ + 9x² + 6x – 16

the measure of the length of the box = x+2

the measure of the height of the box = x+8

formula for Volume of Prism is

Volume = l × w × h

where l = length of the prism,

w = width of the prism and

The probability that at least five wear sunglasses is 0.9464

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%).

In a random sample of 10 adults, the probability that at least five wear sunglasses

P(X ≥ 5) = P(X = 5) + P(X = 6 ) + P(X=7) + P(X=8) + P(X=9) + P(X=10)

now input the coordinates and slope(m) given into y=mx+b to find b:

-6=-7/2(-4)+b

-6=28/2+b

-6=14+b

-6-14=b

b=-20

Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

The same slope due to a parallel line,

Take away m from the above equation since it is in the y = mx+b form:

m= -7/2

Now, enter the given coordinates and slope(m) into y=mx+b to determine b:

Health care refers to the maintenance or improvement of an individual's physical or mental health through the prevention, diagnosis, and treatment of illness, injury, or disease. It encompasses a range of services provided by healthcare professionals.

Based on the information provided, Tanya, who has a Bronze level plan and only goes to the doctor once a year for an annual exam, is likely to pay the least for healthcare.

Bronze level plans typically have lower monthly premiums but higher out-of-pocket costs for healthcare services, such as copays, deductibles, and coinsurance.

Since Tanya only goes to the doctor once a year, she is unlikely to meet her deductible or incur significant out-of-pocket costs.

In contrast, options B, C, and D involve more frequent or more serious healthcare needs, which would likely result in higher out-of-pocket costs for healthcare services.

The integers are  3√25, -185/5, rational = -1/4, 0.75, 3√25, -185/5, 4√8, irrational = √13,

An integer is the number zero (0), a positive natural number (1, 2, 3, etc.) or a negative integer with a minus sign.

A rational number is any number that can be written as a fraction, where both the numerator na demoninator that is the top and the bottom number  are integers, and the denominator is cannot be zero

An irrational number is a type of real number which cannot be represented as a simple fraction.

A integer can always be a rational number but vice versa is not true.

Integer = 3√25 = 3x5 = 15

-185/5 = -37

rational = -1/4, 0.75, 3√25, -185/5, 4√8

irrational = √13,

Therefore, the integers are  3√25, -185/5, rational = -1/4, 0.75, 3√25, -185/5, 4√8, irrational = √13,

So , the speed of the airplane with the wind is 560/2 = 280 miles per hour

also given that
