Answer:

31

Step-by-step explanation:

2 out of 35 are chess club members.

The fraction of chess club members in the survey is 2/35.

Now we find 2/35 of 550.

2/35 * 550 = 1100/35 = 31.43

Answer: 31

If there are 550 students at her school, then there are 31 chess club members in the entire school.

It is a branch of mathematics that deals with the occurrence of a random event.

If Carmen surveyed a random sample of 35 students and found that 2 are chess club members.

We can set up a proportion to solve for this:

2/35 = x/550

where x is the number of chess club members in the entire school.

To solve for x, we can cross-multiply and simplify:

2 × 550 = 35 × x

1100 = 35x

Divide both sides by 35.

x = 1100/35

x ≈ 31.43

Therefore, we can estimate that there are approximately 31 chess club members in the entire school.

Answer:

y=(x-4)²-4

Step-by-step explanation:

Our x-intercepts are (2,0) and (6,0) so we can state them as expressions and expand:

(x-2)(x-6)=0 [Remember that (2,0) is the solution to x-2=0 just as (6,0) is the solution to x-6=0]

x²-8x+12=0 (Standard Form)

x²-8x+12+4=0+4 (Completing the square)

x²-8x+16=4

(x-4)²=4

(x-4)²-4=0

Therefore, our equation for the graph in vertex form is y=(x-4)²-4

Answer:

What we have here is experimental probability:   12 heads out of 20 tosses. The fraction 12/20 reduces to  6/10, or 0.60, which corresponds to 60%.

Answer: 506 square units (answer choice B)

Step-by-step explanation:

The formula for the surface area of a triangular prism is:

SA = bh + 2ls + lb,

where b is the base, h is the height, l is the length, and s is the side of the triangle.

In this case, the base is 7 (Y), the height is 8 (h), the length is 18 (Z), and the side of the triangle is 9 (X).

So, by subsituition, we have:

SA = (7)(8) + 2(18)(9) + (18)(7)

SA = 56 + 324 + 126

SA = 506

The surface area is 506 square units.

It's not clear whether you're talking about the bounded region to the left or right of the y-axis, but due to symmetry it doesn't really matter.

The two curves y = 8 and y = 8x ² intersect for

8 = 8x ²   →   x ² = 1   →   x = -1, x = 1

but we only care about one of these; take the positive solution, so the region of interest lies to the right of the y-axis.

Each washer has an outer radius (distance from the "top" curve to the axis of revolution) of 8 and an inner radius (distance from the "bottom" curve) of 8x ². Take the heights to be some small length ∆x . Then each has a volume of π (outer radius)² - π (inner radius)², or

π (64 - 64x ⁴) ∆x

Now take n such washers, take their sum, and let n → ∞ and ∆x → 0. This amounts to computing the integral,

∫₀¹ π (64 - 64x ⁴) dx = π (64x - 64/5 x ⁵) |₀¹

… = π (64 - 64/5)

… = 256π/5

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

The required one banana cost, one apple cost, and a single fraction $1.45/b, $1.45/b, and  0.54* a/b respectively.

In mathematics, it deals with numbers of operations according to the statements.

There is b number of bananas and a number of apples.
The cost of total bananas and apples is $1.45 and $2.35.

(a) Cost of one banana is,
       For b bananas = $1.45
              dividing both side by b
             b/b bananas = $1.45/b
              1 banana = $1.45/b

(b) Cost of one apple is,

For a apples = $2.35
dividing both side by a
         a/a = $2.35/a
      1 apple = $2.35/a

(c) Single fraction is given by = cost of one banana/ cost of one apple
                                                =    (1.25/b) / (2.35/a)
                                                =   0.54* a/b

Thus the required one banana cost, one apple cost and single fraction $1.45/b, $1.45/b, and  0.54* a/b respectively.

Answer:

  -10

Step-by-step explanation:

The first step is to write what you mean. We think you mean (-1000)^(1/3).

If you've been paying attention to place-value, and/or cubes of small integers, you already know that 10^3 = 1000. Since we're concerned with an odd power, we also know ...

  -1000 = (-10)^3

Then your expression is ...

  (-1000)^(1/3) = ((-10)^3)^(1/3) = (-10)^(3/3) = (-10)^1 = -10

__

Some calculators can evaluate this for you (see attached).

Some calculators and spreadsheets use logarithms to compute roots or fractional powers, so will give you an error when you try to compute this. You should know that an odd-index root of a negative number (here, 3rd root of -1000) has the same sign as the number: negative. Then you can use your calculator to compute the positive root and add the sign yourself:

  (-1000)^(1/3) = -(1000^(1/3)) = -(10) = -10

_____

Of course, a 1/3 power is the same as a cube root. Your calculator may have a cube root button that works just fine with negative numbers.

Answer:3418

Step-by-step explanation:

The volume of the cylinder, rounded to the nearest tenth, is approximately 3418.1 ft³.

To find the volume of a cylinder, you can use the formula:

Volume = π * r² * h

Given:

Radius (r) = 8 ft

Height (h) = 17 ft

Plugging these values into the formula, we can calculate the volume:

Volume = π * (8 ft)² * 17 ft

= π * 64 ft² * 17 ft

≈ 3418.05 ft³

Rounding the volume to the nearest tenth, we get:

Volume ≈ 3418.1 ft³

Therefore, the volume of the cylinder, rounded to the nearest tenth, is approximately 3418.1 ft³.
