Answer:

The minimum number of hours is 43.

Step-by-step explanation:

Total money required = $ 800

Saved money = $ 290

Per hour income = $ 12

Let the number of hours be n.

According to the question

290 + 12n \geqslant 800\\\\12 n \geqslant 510\\\\n\geqslant 42.5

So, the minimum number of hours is 43.

Answer:

800 - 290 = 510.  510 = 12h

Step-by-step explanation:

$800 is the amount he is trying to save.

$290 is the amount he has so far.

$800 - $290 = $510.

$510 is the amount more he needs to earn.

12h.

12 represents the amount he is paid every 1 hour

H represents the hours he works.

For a discrete random variable that takes a value of 8 with probability .75 and a value of -4 with probability of .25, what is t
klasskru [66]

Answer:

5.20

Step-by-step explanation:

X : ______ 8 ____ - 4

P(X) : ___ 0.75 __ 0.25

The expected mean E(x) :

E(x) = ΣX / n

n = sample size = 2

E(x) = (8*0.75) + (-4*0.25)

E(x) = 6 - 1

E(x) = 5

The standard deviation : sqrt(Var(x))

Var(x) = Σx²p(x) - E(x)²

Var(x) = (8^2 * 0.75) + (-4^2 * 0.25)) - 5^2

Var(x) = ((64 * 0.75) + (16* 0.25)) - 25

Var(x) = (48 + 4) - 25

Var(X) = 27

Standard deviation = sqrt(27)

Standard deviation (x) = 5.1961524

Standard deviation = 5.20

enyata [817]

Answer:

<em>A</em>

Step-by-step explanation:

My reasoning is because right above the question it says "Given: DEF" meaning that you would go in order of <em>DEF</em><em>.</em>

<em>So</em><em>,</em> looking at the triangle, <em><u>D would be 10, E would be 13, and F would be 15.</u></em>

Surface area!!!!!!!!!!!!!!
gtnhenbr [62]

Answer:

D.347.45cm²

Step-by-step explanation:

The formula to find the surface area of a rectangular prism is:

A=2(wl+hl+hw)

Let's break down our variables:

Length = 11.73cm

Width = 9.08cm

Height = 3.23cm

Let's substitute the values:

A=2)(9.08)(11.73)+(3.23)(11.73)+(3.23)(9.08))

A=2(106.508+37.888+29.328)

A=2(173.7247)

A=347.45cm²
