Answer:

Step-by-step explanation:

$\frac{x + 5}{ {x}^{2} } - \frac{2}{5x}$

Write all the numbers above the least common denominator ${5x}^{2}$

$\frac{5(x + 5) - 2x}{5 {x}^{2} }$

Distribute 5 through the parentheses

$\frac{5x + 25 - 2x}{5 {x}^{2} }$

Collect like terms

$\frac{3x + 25}{5 {x}^{2} }$

Hope this helps...

Good luck on your assignment...

Answer:

third option

Step-by-step explanation:

Given

$\frac{x+5}{x^2}$ - $\frac{2}{5x}$

We require the denominators to be common before subtracting.

Multiply numerator/ denominator of first fraction by 5

Multiply numerator/ denominator of second fraction by x

$\frac{5(x+5)}{5x^2}$ - $\frac{2x}{5x^2}$

Simplify numerator leaving common denominator

= $\frac{5x+25-2x}{5x^2}$

= $\frac{3x+25}{5x^2}$

In an experiment, a ball is drawn from an urn containing 11 orange balls and 8 blue balls. If the ball is orange, three coins ar

Sophie [7]

Answer:

a) 4

b) 12

Step-by-step explanation:

Since, when an orange ball is drawn, three coins are tossed. So, sample points are OHHH, OHHT, OHTH, OHTT. OTHH, 0THT, OTTH, OTTT

So, clearly, 8 sample points will have an orange ball.

When a blue ball is drawn, two coins are tossed. So, sample points are BHH,BHT,BTH,BTT.

So, clearly, 4 samples points will when a blue ball is drawn.

Total samples points=4+8=12

UNO [17]

Answer:

we reject H₀

Step-by-step explanation: Se annex

The test is one tail-test (greater than)

Using α = 0,05 (critical value ) from z- table we get

z(c) = 1,64

And Test hypothesis is:

H₀ Null hypothesis μ = μ₀

Hₐ Alternate hypothesis μ > μ₀

Which we need to compare with z(s) = 2,19 (from problem statement)

The annex shows z(c), z(s), rejection and acceptance regions, and as we can see z(s) > z(c) and it is in the rejection region

So base on our drawing we will reject H₀

withdraws $ from bank account once each day for days. What integer represents the change in the amount in the account? Use pen

REY [17]

Answer:

a. Sam withdraws $11 from his account. That means his account balance reduces by $11 so the integer is -$11.

He does this 4 times so;

= 4 * -11

= -$44

b. He then deposits $11 once every day for 4 days.

= 4 * 11

= $44

c. The integer for withdrawals is a negative figure to show that the balance was decreasing. The Integer for deposits is positive to show that the balance was increasing.
