Answer:

Simplest form = -w - 2

Step-by-step explanation:

Given expression,

→ -24 - 12w

→ -12w - 24

Simplifying the expression,

→ -12w - 24

→ (-12w - 24)/12

→ -w - 2

Hence, the answer is -w -2.

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 train will catch up with the dog in 1.996 seconds

The problem is solved using the formula for speed which is

distance / time

speed of the train = length of track / time

= 1900 / 40

= 475 m/s

speed of the dog is given to be 6 m/s

The relative velocity = 475 - 6 = 469 m/s

The time to catch up is calculated using relative velocity

469 * time = 936 meters

time = 936 / 469

= 1.996 seconds

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

construct a right triangle with legs 40.66 and 50-40.66 = 9.34.  then sum the legs' squares, and take the square root to get 41.72 feet

distance from home to 2nd = hypotenuse of a right triangle with sides 50 and 50, and angle of 45 degrees

50^2 + 50^2 = 2(2500) = 5000.  sqr5000= 70.71,  subtract 57.5.    70.71-57.5= 13.21 feet from pitcher to 2nd

The speed of the plane is 252 miles per hour and the speed of the wind is 28 miles per hour .

In the question ,

it is given that ,

the airplane covers the distance of 560 miles in 2 hours with the wind,

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

also given that

airplane covers the distance of 560 miles in 2.5 hours against the wind ,

So , the speed of the plane with the wind = 560/2.5 = 224 miles per hour .

let the speed of the airplane be "a" miles per hour ,

and let the speed of the wind be "b" miles per hour ,

So , equation of speed  with the wind is denoted by

a + b = 280

and the equation of speed against the wind is denoted by

a - b = 224

Adding both the equations , we get

2a = 504

a = 504/2

a = 252 miles per hour

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)

P(X ≥ 5) = 10[tex]C_{5}[/tex] × [tex](0.7)^{5}[/tex]×[tex](0.3)^{5}[/tex] +  10[tex]C_{6}[/tex]×[tex](0.7)^{6}[/tex]× [tex](0.3)^{4}[/tex]+ 10[tex]C_{7}[/tex]×[tex](0.7)^{7}[/tex]×[tex](0.3)^{3}[/tex] + 10[tex]C_{8}[/tex]× [tex](0.7)^{8}[/tex]×[tex](0.3)^{2}[/tex] +10[tex]C_{9}[/tex] ×[tex](0.7)^{9}[/tex]×[tex](0.3)^{1}[/tex]+10[tex]C_{10}[/tex]×[tex](0.7)^{10}[/tex]×[tex](0.3)^{0}[/tex]

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.
