Answer:

$325.50

Step-by-step explanation:

1) 210÷100 = 2.1

  2.1×55 = 115.5

  210 + 115.5 = 325.5

2) 210×55 = 11550

   11550÷100 = 115.5

   210 + 115.5 = 325.5

Answer:

x = 18

Step-by-step explanation:

The line joining 2 midpoints of the non parallel sides of a trapezoid is 1/2 the sum of the two parallel lines.

Put in much simpler language XY = 1/2 (BC + AD)

4x - 2 = 1/2 (6x + 1 + x)                         Combine the right

4x - 2 = 1/2 (7x + 1)                               Multiply by 2

8x - 4 = 7x + 1                                       Add 4 to both sides

8x = 7x + 5                                           Subtract 7x

x = 5

But what you want is the length of XY

XY = 4x - 2 = 4*5 - 2 = 18

Sorry I noticed too late that I used x for s. The answer would still be 18.

The function is an exponential growth function

The function is given as

y=2(1.06)^9

We can begin by rewriting the given equation as:

y = 2 * 1.06t

So, we have

y = 2 * (1 + 0.06)^t

Now we can see that the equation is in the form y = a*b^t,

where a = 2 and b = 1.06^9

This equation represents exponential growth because the base of the exponent, b = 1.06, is greater than 1.

We can re-write it in the form y = a(1+r)t,

we can find the value of r by subtracting 1 from 1.06 which is 0.06 and the value of a is 2.

so we have y = 2(1+0.06)^t

So, the equation represents exponential growth with a = 2 and r = 0.06

Answer:

The circular is around 305 cm in circumeference.

The circumference of a circle is given by the formula:

C = πd

where d is the diameter of the circle.

Substituting d = 97 cm and using the value of π to be 3.14159, we get:

C = πd

C = 3.14159 × 97 cm

C ≈ 304.731 cm

Rounding this to 3 significant figures, we get:

C ≈ 305 cm

Therefore, the circumference of the circle is approximately 305 cm.

we have the base, but we need the height

we will find it using the area:

height = 336 / 16 = 21

The value of x is approximately 8.4.To find the value of x, we can use the fact that CD is parallel to BE to establish a relationship between the corresponding sides of the two triangles formed.

Based on the given information, we have:

DC = 4x - 11

BE = 6

AD = 15

ED = 4

Using the corresponding sides in the triangles, we can set up a proportion:

AD/ED = CD/BE

Substituting the known values:

15/4 = (4x - 11)/6

Now we can cross-multiply to solve for x:

6 * 15 = 4 * (4x - 11)

90 = 16x - 44

Adding 44 to both sides:

134 = 16x

Dividing both sides by 16:

x = 8.375

Rounded to the nearest tenth, x ≈ 8.4.

Convergence

Step-by-step explanation:

Use the Squeeze Theorem,

I know that

\( \frac{k \sin {}^{2} (k) }{1 + k {}^{3} } \)

lies between 0 and 1 so

\(0 \leqslant \frac{k \sin {}^{2} (k) }{1 + {k}^{3} } \leqslant \frac{k}{1 + k {}^{3} } \)

The final series behaves like

\( \frac{1}{k {}^{2} } \)

Using the p series, since p is 2, the series

\( \frac{k}{1 + k {}^{3} } \: converges\)

Since the 0 and k/1+k^3 converges, the series converge.

Answer:

The probability of getting at least one hit in 5 games is 0.772

Step-by-step explanation:

The correct question is as follows;

One interpretation of a baseball player's batting average is as the empirical probability of gettig a hit each time the player goes to bat. If a player witt a batting average of 0.256 bats 5 times in a game, and each at-bat is an independent event, what is the probability of the player getting at least one hit in the game?

We proceed with the answer as follows;

Here, we want to calculate the probability of a player with a certain batting average getting at least one hit in a game if he bats 5 times

Mathematically, Probability of getting at least one hit in 5 games = 1 - Probability of getting no hit in 5 games

Let p = probability of getting hit in a game = 0.256

q = Probability of getting no hit in a game = 1-0.256 = 0.744

So the probability of getting no hits in 5 games will be 0.744^5 = 0.228

Thus, the probability of getting at least one hit in the 5 games = 1 - 0.228 = 0.772

The correct answer is B. The sample represents a proportion of the population.

A point estimate is a single value used to estimate a population's unknown parameter. The sample proportion (denoted by p), in the context of determining the population proportion, is a widely used point estimate. The sample proportion is determined by dividing the sample's success rate by the sample size.

The sample must be representative of the population for it to be a reliable point estimate of the population proportion. To accurately reflect the proportions of various groups or categories present in the population, the sample should be chosen at random.

Write 2^60 as an exponent with a base of:

a) 8

b) 16

c) 32

the answer is :

8^20 (eight to the twentieth power)

\(2^{60}\) is equivalent to \(16^{15}\).

We can rewrite the expression by means of the following power property, that is to say:

\(a^{b\cdot c} = (a^{b})^c\), \(a, b, c\in \mathbb{N}\) (1)

Where \(a\) and \(a^{b}\) are bases.

If we know that \(a = 2\) and \(b\cdot c = 60\), then the equivalent expression is:

\(2^{60} = 2^{4\cdot 15} = (2^{4})^{15} = 16^{15}\)

Hence, \(2^{60}\) is equivalent to \(16^{15}\).

Step-by-step explanation:

\((9*7) + 7 - 8 = ?\)

We can solve this by using the PEMDAS concept where,

So, to solve this, we need to solve the numbers in the parentheses by doing the requested operation (here it is, mutiplucation).

\((9*7) + 7 - 8\\= (63) + 7 - 8\)

Now, by looking at the PEMDAS rule, we can see that the next step is addition (as, we don't have to divide in this question).

\((63) + 7 - 8\\= 63 + 7 - 8\\= 70 - 8\)

Now, subtract 8 from 70 .

The difference between the new, colder temperature and the original temperature is 30 ° C.

"Temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). Temperature is not the equivalent of the energy of a thermodynamic system; e.g., a burning match is at a much higher temperature than an iceberg, but the total heat energy contained in an iceberg is much greater than the energy contained in a match. Temperature, similar to pressure or density, is called an intensive property—one that is independent of the quantity of matter being considered—as distinguished from extensive properties, such as mass or volume."

Given,

The old temperature is = 18°C

The new temperature is = -12°C

The difference in temperature is \((-12\°C - 18\°C) = 30\°C\)
