Answer:

The unknown number is 1.

Step-by-step explanation:

You have to form an expression. So let's make the unknown number as x. Firstly, a number is multiplied by 5 :

$x \times 5$

$= 5x$

Secondly, 5 is added to product and you will get 10 :

$5x + 5 = 10$

Lastly, you have to solve :

$5x + 5 = 10$

$5x = 10 - 5$

$5x = 5$

$x = 5 \div 5$

$x = 1$

54% of 630 = 0.54 * 630 or approximately <u>340</u> of the 630 were planning to vote for the candidate.

51% of 1010 = 0.51 * 1010 or approximately <u>515</u> of the 1010 were planning to vote for the candidate.

This means that the voter support for this candidate increased.

On a recent quiz, the class mean was 70 with a standard deviation of 2.1. Calculate the z-score (to 4 decimal places) for a pers

Igoryamba

The equation to find a z score is (x- mean)/(standard deviation)

So, in this case the equation would be
(76-70)/(2.1)

For,
X=76
Mean=70
Standard Deviation= 2.1

After solving we find that the z score equals 2.85714

or

2.8571

Find the intercepts of function f(x) = -x³ / x²+9

Brrunno [24]

Answer:

x-intercept (0,0)

y-intercept (0,0)

Step-by-step explanation:

The given function is

$f(x) = \frac{ - {x}^{3} }{ {x}^{2} + 9}$

To find the x-intercept, we substitute y=f(x)=0

This implies that:

$\frac{ - {x}^{3} }{ {x}^{2} + 9 } = 0$

$- {x}^{3} = 0 \cdot( {x}^{2} + 9)$

$- {x}^{3} = 0$

${x}^{3} = 0$

$x = 0$

Therefore the x-intercept is (0,0)

To find the y-intercept we substitute x=0

$f(0) = \frac{ - {0}^{3} }{ {0}^{2} + 9 }$

$f(0) = \frac{0}{9} = 0$

The y-intercept is (0,0)
