Find axis of symmetry

The rock will take 10.25 seconds to hit the ground, as the amount determined by the formula h=352-16t^(2).

The given equation is h=352-16t^(2). This equation can be used to calculate the time it will take for a rock to hit the ground after it has been dropped from a tower that is 352 feet high. The equation states that the rock's height (h) is equal to 352 minus 16 times the square of the time (t). To find the time it will take for the rock to hit the ground (h=0), we can rearrange the equation to solve for t. The rearranged equation is t=sqrt((352-0)/16), which simplifies to t=10.25. This means that the rock will take 10.25 seconds to hit the ground. This can also be expressed in tenths of a second as 102.5, which is the same as 10.25 seconds.

t= sqrt((352-0)/16)

t= sqrt(22)/4

t= 10.25

Answer:

Timmy has a collection of 95 coins consisting of dimes and nickels in his bank, The total value of his bank is $6.50. We can infer that he has 60 nickels and 35 dimes.

In algebra, an equation is a declaration of equivalence that includes one or more variables or unknowable quantities.

Given,

Timmy has a collection of 95 coins consisting of dimes and nickels in his bank, The total value of his bank is $6.50.

Set d and n to the appropriate numbers.

Timmy has 95 coins in total, all of which are dimes and nickels, as far as we know.

Equation,

So d + n = 95

His bank is worth a total of $6.50.

A nickel is worth $0.05, while a dime is worth $0.10.

So

0.10d + 0.05n = $6.50

Take note that we have just produced an equation system that we can solve.

The two equations exist.

D + n = 95

and

0.10d + 0.05n = 6.50.

The replacement approach is probably going to be the simplest way to solve this problem out of all the options available to us.

First, we'll want to change the second equation's terms so that one of the variables is defined.

d+ n = 95

Take d off on both sides.

n = 95 - d

Now, let's define "n."

After defining one of the variables, we can now enter (or replace) its value in the other equation. After replacing it, we can find a solution for the other variable.

0.10d + 0.05n = 6.50

n = 95 - d

0.10d + 0.05(95 - d) = 6.50

We now determine d.

0.10d + 0.05(95 - d) = 6.50

distribution of the 0.05 in step 1

0.05 × 95 = 4.75

and

0.05 × -d = -0.05d

0.10d + 4.75 - 0.05d = 6.50

Step 2: Add like terms together (0.10 - 0.05) to get 0.05

0.05d + 4.75 = 6.50

step 3: Take 4.75 off of each side.

0.05d = 1.75

step 4: Subtract 0.05 from both sides.

0.05d / 0.05 = d and 1.75 / 0.05 = 35

d = 35

Now that we know the value of one variable, we can use it to solve for the second variable by plugging it into one of the equations ( note that the equation that we use does not matter, we will acquire the same answer )

d + n = 95

d = 35

35 + n = 95

Take 35 off both sides.

n = 60

We can infer that he has 60 nickels and 35 dimes.

There were 37 kisses at the family reunion. Probability is used to make predictions and inform decision-making.

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain to occur.

To find the number of kisses at the family reunion, you can set up the ratio 4 hugs : 1 kiss as a proportion and solve for the number of kisses. Here's how you can do this:

First, cross-multiply to find the total number of hugs and kisses:

4 hugs * 1 kiss = 148 hugs

4 kisses = 148 hugs

Then, divide both sides of the equation by 4 to find the number of kisses:

4 kisses / 4 = 148 hugs / 4

The length of the Arc of the circle is 17.00 units

We should know that the arc of the circle is part of the circumference of the circle cut off by the radii of the circle.

To find the probability that Y1 = 71 and Y2 = y2, we can write G(y1, y2) = P(Y1 = 71, Y2 = y2).

To find the probability that Y1 = 71 and Y2 = y2, we need to consider the possible values of X1 and X2 that could lead to these values of Y1 and Y2. The probability density functions (PDFs) of an exponential distribution with mean 1000 is f(x) = 1/1000 * e^(-x/1000). Therefore, the probability of this event is

Another possibility is that X1 = y2 and X2 = 71. The probability of this event is

Since these two events are mutually exclusive and exhaust all possible ways that Y1 can equal 71 and Y2 can equal y2, the probability of these events occurring is the sum of these probabilities. Therefore,

Note that this expression is only valid when 0 < 71 < y2 < ∞ since these are the conditions under which Y1 can equal 71 and Y2 can equal y2.

The new price of the item is equivalent to $3.25.

Given is that the price of an item has been reduced by 95%. The original price was $65

Assume the new price to be $[x]. So, we can write -

x = 65 - {95% of 65}

x = 65 - {(95/100) x 65}

x = 65 - {6175/100}

x = 65 - 61.75

Using the given provided probability value of getting three heads, The statement which best follow the given condition is If you flip 3 coins 5000 times, the percentage of time you get three heads will be very close to 12.5%.

What do you mean by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

According to the given question:

Assume you have a fair coin, which means it will likely land tails up 50% of the time and heads up 50% of the time. Let's say you flip it three times, each time independently. What is the likelihood that it will land heads up first, followed by a tails up landing?

The solution is 1/8, or 12.5%.

coin flipped = 3 times.

probability of getting three heads = 0.125

Since, This probability explains the chances of landing three heads which is 0.125 which in terms of percentage is 12.5% .

So, The statement is If you flip 3 coins 5000 times, the percentage of time you get three heads will be very close 12.5%.
