The problem is to evaluate the radical -³√1000. To solve this, we need to re-write the value 1000 into the base of 10 such as 1000=10³.
Then, it changes to -³√10³. We need to pull out the terms out of the radical, thus, we have -1 *10.
Lastly, we multiply -1 to 10 and the answer is -10.

The base of a parallelogram is 18 inches longer than three times the height. The area of the parallelogram is 216 square inches.

nordsb [41]

Answer:

12 inches

Step-by-step explanation:

Let b represent the base

h represents the height

area of the parallelogram = base * height = 216 square inches

From the question'

b = 18 + 3h

Slot in the value of b

216 = (18 + 3h) * h

expand

216 = 18h + 3h^2

subtract 216 from both sides

0 = 18h + 3h^2 - 216

rearrange

3h^2 + 18h - 216 = 0

divide through by 3

h^2 + 6h - 72 = 0

Now, lets solve!

h^2 + 6h - 12h - 72 = 0

h( h + 6 ) - 12(h + 6) = 0

(h - 12) (h + 6) = 0

h - 12 = 0

h = 12

and

h + 6 = 0

h = - 6

Taking the positive value of h

Hence, the height is 12 inches

Lets check

when h = 12 inches

Area of the parallelogram = 18* 12 = 216 square inches .... correct

when h = -6inches

A = 18 * -6 ≠ 216 square inches

So height is 12 inches

A card is randomly selected from a standard

Anni [7]

Answer:

5.8% or 6%

Step-by-step explanation:

6 face cards in a deck minus the red ones so it would be [6-3=3]

52 cards are in a deck and you have 3 black face card so it would be [3/52=0.0576]

Then to get your percentage it would be [0.0576 x 100=5.76%]

5.76 rounded up is 6%

A report states that the mean yearly salary offer for students graduating with a degree in accounting is $48,734. Suppose that a

DENIUS [597]

Solution :

To claim to be tested is whether "the mean salary is higher than 48,734".

i.e. μ > 48,734

Therefore the null and the alternative hypothesis are

$H_0 : \mu = 48,734$

and $H_1 : \mu > 48,734$

Here, n = 50

$\bar x = 49,830$

s = 3600

We take , α = 0.05

The test statistics t is given by

$t=\frac{\bar x - \mu}{\frac{s}{\sqrt n}}$

$t=\frac{49,830 - 48,734}{\frac{3600}{\sqrt 50}}$

t = 2.15

Now the ">" sign in the $H_1$ sign indicates that the right tailed test

Now degree of freedom, df = n - 1

= 50 - 1

= 49

Therefore, the p value = 0.02

The observed p value is less than α = 0.05, therefore we reject $H_0$ . Hence the mean salary that the accounting graduates are offered from the university is more than the average salary of 48,734 dollar.
