The water pressure on a submerged object is given by P = 64d, then the value d is 10.5 feet.

a. D = P/64 is the solution to the formula's "d" subject.

b. The depth of a submerged object at a pressure of 672 pounds per square foot is 10. 5 feet.

A function can be defined as an expression, law or rule that shows the relationship between two variables.

Given the role as;

P = 64d

Where;

P stands for pressure in pounds per square foot.

The object's depth, d, is expressed in feet.

Now let's center the formula on the variable "d."

Both sides of the equation are divided by the variable "d64-based "'s coefficient. This is carried out so that the variable can stand on its own.

We have.

P/64 = 64d/64

d = P/ 64

If there is pressure, P is equivalent to 672 pounds per square foot.

When the value of the variable is inserted into the formula, we obtain;

d = P/64

Then,

d = 672/64

Discover the quotient.

d = 10. 5 ft.

Therefore,

The water pressure on a submerged object is given by P = 64d, then the value d is 10.5 feet.

a. D = P/64 is the solution to the formula's "d" subject.

b. The depth of a submerged object at a pressure of 672 pounds per square foot is 10. 5 feet.

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second poin

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the value to be determined be = a

Now , the slope of the line be = m

The value of m = 3/2

So , Slope m = 3/2

And , the value of a is calculated by

Answer: y=x−2 y = x − 2

Step-by-step explanation:

The parabola x = √(y - 9) opens upwards.The given parabolic equation is x = √(y - 9). Let's identify the direction of opening of this parabola.The general form of the equation of a parabola is y = a(x - h)² + k.

Comparing this to the given equation, we can see that h = 0 and k = 9. The vertex is therefore (h, k) = (0, 9). Now, let's determine whether the parabola opens upwards or downwards.

If the coefficient of (x - h)² is positive, the parabola opens upwards, and if it's negative, the parabola opens downwards. In this case, since the coefficient of (x - h)² is 1, which is positive, the parabola opens upwards.

Therefore, the parabola x = √(y - 9) opens upwards.

Step-by-step explanation:

Answer:

y = x + 1

Step-by-step explanation:

Parallel lines have same slope.

y = x - 1

Compare with the equation of line in slope y-intercept form: y = mx +b

Here, m is the slope and b is the y-intercept.

m =1

Now, the equation is,

         y = x + b

The required line passes through (-3 ,-2). Substitute in the above equation and find y-intercept,

        -2 = -3 + b

  -2 + 3 = b

         \(\boxed{b= 1}\)

    Equation of line in slope-intercept form:

                  \(\boxed{\bf y = x + 1}\)      

The equation is :

Solution:

If two lines are parallel to each other, then their slopes are equal. The slope of y = x - 1 is 1. Hence, the slope of the line that is parallel to that line is 1.

We shouldn't forget about a point on the line : (-3, -2).

I plug that into a point-slope which is :

\(\sf{y-y_1=m(x-x_1)}\)

Slope is 1 so

\(\sf{y-y_1=1(x-x_1)}\)

Simplify

\(\sf{y-y_1=x-x_1}\)

Now I plug in the other numbers.

-3 and -2 are x and y, respectively.

\(\sf{y-(-2)=x-(-3)}\)

Simplify

\(\sf{y+2=x+3}\)

We're almost there, the objective is to have an equation in y = mx + b form.

So now I subtract 2 from each side

\(\sf{y=x+1}\)

P(getting out on first try) = 5/45 = 1/9, P(getting out on second try) = (5 + 1)/40 = 3/20, P(all players getting out on first try) = (1/9) * (3/20) * (3/19) * (3/18) = 1/3690, P(none getting out on first try) = 1 - P(at least one getting out on first try), P(at least one getting out on first try) = 1 - P(none getting out on first try).

According to the First Law of Probability, the outcomes of one chance event have no bearing on those of succeeding chances occurrences.

1. The odds of drawing a 1 or a 2 are added to determine the likelihood that the first player exits the game after the first card. There are 45 cards in all, 5 of which have a 1 or a 2, hence the probability of getting out on the first try is P(getting out on first try) = 5/45 = 1/9.

2. There are still 40 cards in the deck if the first player is already out, and the second player can exit the game by drawing a 1, a 2, or a SORRY. The probability of getting out on the second try is P(getting out on second try) = (5 + 1)/40 = 3/20 since there are 5 cards with a 1 or a 2, plus 1 SORRY card.

3. The first player must draw a 1 or a 2, the second player must draw a 1, the third player must draw a 2, the fourth player must draw a SORRY, and so on. The likelihood that this will occur is P (all players successfully exiting the game on their first attempt) = (1/9) * (3/20) * (3/19) * (3/18) = 1/3690.

4. The complement of the likelihood that at least one player goes out on their first try is the probability that none of the players get out on their first try. So, if we compute the likelihood that at least one player will be eliminated after their first attempt and deduct it from 1, we obtain: P (none succeeding on the first attempt) = 1 - P (at least one getting out on first try).

5. The chance that no players get out on their first try, which we computed in part 4, may be used to calculate the probability that at least one player gets out on their first try: P(at least one getting out on first try) = 1 - P. (none getting out on first try).

Given triangle ABC,

and D is a point on AB and E is a point on AC,

and forms a triangle ADE,

and  DE is parallel to AC,

taking ΔABC and ΔBDE

∠B = ∠B  (common angle)

1. Number of athletes did not own any of the three items = 259 - 228

= 31.

2. Number of athletes own a convertible and a TV but not a store = 44 - 9

= 35.

3. Number of athletes own a convertible or a TV = 110 + 91 - 44

= 157.

4. Number of athletes owned exactly one type of item = 60 + 13 + 71 = 144.

5. Number of athletes owned at least one type of item = 259 - 31

= 228

6. Number of athletes own a TV or a store, but not a convertible = 13 + 34 +71

= 118.

The number of athletes did not own any of the three items need to subtract the number of athletes who own at least one item from the total number of athletes surveyed.

Total number of athletes surveyed = 259

Number of athletes own at least one item = 110 + 91 + 120 - 15 - 43 - 44 + 9 = 228

Number of athletes who did not own any of the three items = 259 - 228 = 31.

The number of athletes who owned a convertible and a TV but not a store need to subtract the number of athletes who own all three items from the number of athletes who own a convertible and a TV.

Number of athletes who own a convertible and a TV = 44

Number of athletes who own all three items = 9

Number of athletes who own a convertible and a TV but not a store = 44 - 9 = 35

The number of athletes who owned a convertible, or a TV need to add the number of athletes who own a convertible to the number of athletes who own a TV and then subtract the number of athletes own both a convertible and a TV.

Number of athletes who own a convertible or a TV = 110 + 91 - 44

= 157.

The number of athletes owned exactly one type of item need to add up the number of athletes who own a convertible only the number of athletes own a TV only and the number of athletes who own a store only.

Number of athletes own a convertible only = 110 - 15 - 9 = 86

Number of athletes own a TV only = 91 - 44 - 9 = 38

Number of athletes own a store only = 120 - 15 - 43 - 9 = 53

Number of athletes owned exactly one type of item = 60 + 13 + 71 = 144.

The number of athletes who owned at least one type of item can use the result from part (1).

Number of athletes who owned at least one type of item = 259 - 31

= 228

The number of athletes who owned a TV or a store but not a convertible need to subtract the number of athletes who own all three items, and the number of athletes own a convertible and a TV from the number of athletes own a TV or a store.

Number of athletes own a TV or a store = 91 + 120 - 43 - 9 = 159

PART A: After one year, we can calculate the amount of money each person has in their respective accounts.

For Linda's account:

Principal amount = $610

Interest rate = 1.2%

\(Interest $ earned = Principal $ amount \times (Interest rate/100) = $610 \times (1.2/100) = $7.32\)

\(Total $ amount after one year = Principal amount + Interest earned = $610 + $7.32 = $617.32\)

For Enrique's account:

Principal amount = $590

Interest rate = 3.9%

\(Interest $ earned = Principal amount \times (Interest rate/100) = $590 \times (3.9/100) = $22.91\)

Total amount after one year = Principal amount + Interest earned = $590 + $22.91 = $612.91

Comparing the two amounts, after one year Linda has more money.

The difference in the amount is:

$617.32 - $612.91 = $4.41

Therefore, Linda has $4.41 more than Enrique after one year.

PART B: After a second year, we need to calculate the amounts again.

For Linda's account:

Principal amount = $617.32

Interest rate = 1.2%

\(Interest earned = Principal amount \times (Interest rate/100) = $617.32 \times (1.2/100) = $7.41\)

Total amount after the second year = Principal amount + Interest earned = $617.32 + $7.41 = $624.73

For Enrique's account:

Principal amount = $612.91

Interest rate = 3.9%

\(Interest earned = Principal amount \times (Interest rate/100) = $612.91 \times (3.9/100) = $23.92\)

Total amount after the second year = Principal amount + Interest earned = $612.91 + $23.92 = $636.83

Answer: 7.0%

Step-by-step explanation:

The probability of rolling a sum of 14 is 7.0% because 15/216 = 7.0%

The probability of rolling a sum of 14 is  \(\frac{1}{72}\)    or  0.014.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Formula of probability

Probability(Event) = \(\frac{Favorable Outcomes}{Total Outcomes}\)  

According to the question

rolling a sum of 14

As the maximum sum of two dice is 6+6 = 12

Therefore ,

we will take 3 dices

Now ,

As each dice have 6 different digits and can be repeated

i.e

Total outcomes = 6 * 6 * 6 = 216  

Favorable outcome :

(6,6,2) or (2,6,6) or (6,2,6) = 3 ways

Now,

By using the formula of probability

Probability(Event) = \(\frac{Favorable Outcomes}{Total Outcomes}\)  

Substituting the value in the formula

Probability(Event) = \(\frac{3}{216}\)

Probability(Event) = \(\frac{1}{72}\)    or  0.014

Hence, the probability of rolling a sum of 14 is  \(\frac{1}{72}\)    or  0.014

Let x1 be a standard normal random variable (with mean 0 and variance 1), and let x2 and x3 be two independent random variables, each of which takes the value 1 with probability 1/2 and the value -1 with probability 1/2.

Then x1 x2 and x1 x3 both have a standard normal distribution, because the product of a standard normal random variable and an independent discrete random variable with values ±1 is still a standard normal random variable.

However, x2 and x3 do not have the same distribution, because x2 takes the values ±1 with equal probability, while x3 takes the values ±1 with equal probability.
