If you sold 2000 in the first week and a hundred percent more second week it would be 2000

How many eighth-size parts do you need to model 3/4? explain

Alik [6]

To know the amount of eights you want to get something that looks like ?/8. Basically, the bottom number needs multiplying by 2 (8 divided by 4 is 2). To keep the fraction accurate you multiply by 2 the top and bottom number so you get:
<span>3/4=(3x2)/(4x2)=6/8</span>

In a school with 2,000 students, a random sample of 120 students were asked which fruit is their favorite. Their responses are s

ki77a [65]

We know that

<span>Out of 120 students----------> 34 chose orange as the favorite fruit
</span>Find the <span>percentage
</span><span>percentage=34/120------> 17/60-----> 0.2833------> 28.33%

for </span>2,000 students
0.2833*2000=566.67-----------> about 567 students

the answer is
about 567 students

How do I complete this formal check?

natima [27]

Answer:

Step-by-step explanation:

The first two steps are for the purpose of eliminating fractions. Doing so results in 4(2x - 5) = 9(x - 2), which is to be solved for x.

Perform the indicated multiplication, obtaining:

8x - 20 = 9x - 18.

Then combine like terms: -2 = x, or

x = -2.

To complete the formal check, substitute -2 for x in the first equation. This results in:

(1/3)(-4 - 5) = (3/4)(-2 -2), or

-3 = -3

... which is obviously true.

Video Example EXAMPLE 1 Find the linearization of the function f(x) = x + 1 at a = 3 and use it to approximate the numbers 3.98

Blizzard [7]

Answer:

the linearization is y = 1/4x +5/4

the linearization will produce <em>overestimates</em>

the values computed from this linearization are ...

f(3.98) ≈ 2.245

f(4.05) ≈ 2.2625

Step-by-step explanation:

Apparently, you have ...

$f(x)=\sqrt{x+1}$

from which you have correctly determined that ...

$f'(x)=\dfrac{1}{2\sqrt{x+1}}$

so that f(3) = 2 and f'(3) = 1/4. Putting these values into the point-slope form of the equation of a line, we get the linearization ...

g(x) = (1/4)(x -3) +2

g(x) = (1/4)x +5/4

__

The values from this linearization will be overestimates, as the curve f(x) is concave downward everywhere. The tangent (linearization) is necessarily above the curve everywhere.

__

At the given values, we find ...

g(3.98) = 2.245

g(4.05) = 2.2625
