Answer:

$4000

Step-by-step explanation:

12 x 5 = 60

60% of 10,000 = 6,000

10,000 - 6,000 = $4000

Answer:

a) The difference of a number and six is no less than 15

x - 6 ≥ 15

b) 25 plus a number is at least 13

25 + x ≥ 13

c) g decreased by 25 is at most five

g - 25 ≤ 5

Step-by-step explanation:

a) The difference of a number and six is no less than 15

Let the number be represented by x

We difference is involved in a mathematics question, it requires the application of Subtraction operation, hence:

x - 6 ≥ 15

b) 25 plus a number is at least 13

Let the unknown number be represented by x

When at least is used in Mathematics, is means greater than or equal to a particular value,

Hence,

25 + x ≥ 13

c) g decreased by 25 is at most five

At most means less than or equal to a particular value, hence:

g - 25 ≤ 5

3. A submarine dives at an

Vesna [10]

Answer:

The height of deepness of submarine is 424.1 feet

Step-by-step explanation:

Given as :

The angle at which submarine drives of the surface of water = Ф = 13°

The speed at which submarine travel = s = 760 feet per minute

Let The height of deepness of submarine = h feet

The time taken to reach that deepness = t = 5 minutes

<u>According to question</u>

The height of deepness of submarine = $\dfrac{\textrm speed}{\textrm time}$

i.e h × cos(90 - Ф) = $\dfrac{s}{t}$

Or, h × Sin(Ф) = $\dfrac{\textrm 760 feet per min}{8 min}$

Or, h × Sin(13°) = 95 feet

Or, h × 0.224 = 95 feet

∴ h = $\dfrac{95}{0.224}$

i.e h = 424.10 feet

So, The height of deepness of submarine = h = 424.10 feet

Hence, The height of deepness of submarine is 424.1 feet Answer

nikitadnepr [17]

Answer:

Different values of margin of error for different significance level.

Step-by-step explanation:

We are given the following in the question:

p = 90% = 0.9

Sample size, n 790

We have to find the margin of error.

Formula:

$z_{stat}\sqrt{\dfrac{p(1-p)}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$ME = \pm 1.96\sqrt{\dfrac{0.9(1-0.9)}{790}}\\\\ME = \pm 0.021$

$z_{critical}\text{ at}~\alpha_{0.10} = 1.64$

$ME = \pm 1.64\sqrt{\dfrac{0.9(1-0.9)}{790}}\\\\ME =\pm 0.018$

$z_{critical}\text{ at}~\alpha_{0.10} = 2.58$

$ME =\pm 2.58\sqrt{\dfrac{0.9(1-0.9)}{790}}\\\\ME =\pm 0.028$
