Answer:

I'm pretty sure you just tag or follow them. To add a friend of your own, I have no idea if that's possible. You would have to find the help section and ask.

The nursing department of a college surveyed two hundred graduates from their programs about their current

mel-nik [20]

Answer: The required probability is 0.008.

Step-by-step explanation:

Since we have given that

Probability of bachelor's degree = 0.45

Probability of working in nursing = 0.85

Probability of both = 0.4

So, Probability of getting a graduate is currently working in nursing, given that they earned a bachelor's degree would be :

$P(N|B)=\dfrac{P(N\cap B)}{P(B)}\\\\P(N|B)=\dfrac{0.4}{0.45}\\\\P(N|B)=0.008$

Hence, the required probability is 0.008.

The school baseball team has 3 pitchers. How many different 3-player pitching schedules can the coach choose from?

expeople1 [14]

Answer:

6 schedules

Step-by-step explanation:

First, decide if this situation describes a combination or a permutation by looking at the significance of order. Consider a specific example where the letters A – C represent the 3 different pitchers. The pitching order A, B, C is different from the pitching order B, C, A because the players will be pitching at different times. Therefore, this situation describes a permutation. Use the formula for finding the number of permutations when the number of pitchers is 3, so n = 3, and all 3 are taken at a time, so r = 3 as well.

Bro this makes no sense can someone explain

pantera1 [17]

Answer:

$x=110^o$

Step-by-step explanation:

If AB = AD, then you have that triangle ABD is an isosceles triangle (it has two equal sides). If it is isosceles, then the angles opposite to angles those equal sides must be equal. Then angle ADB = $35^o$ . and by the property of all internal angles of a triangle have to add to $180^o$ , we get that:

$x=180^o-35^o-35^o=110^o$

Find the height of the cylinder whose volume is 1.54 cubic m and radius of the base is 70 cm

Vikki [24]

<h2 /><h2>Question:</h2>

find the height of the cylinder whose volume is 1.54 cubic m and radius of the base is 70 cm

Required diagram :

$\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{ 70 \: cm}}\put(9,17.5){\sf{h}}\end{picture}$

<h3>Solution :</h3>

For a cylinder having a radius r and a height h ;

Volume Of Cylinder :

π r² .

Here , the radius of the cylinder is given as 70 cm and the volume is 1.54 m³ .

Converting ;

1 m³ = 1 × 10⁶ cm³ .
> 1.54 × 10⁶ cm³ .
> 1540000 cm ³.
> π r² h = 1540000
> 22/7 × 70 × 70 × h = 1540000
> 22 × 10 × 70 h = 1540000
> 15400 h = 1540000
> h = 100 cm = 1 m.

The height of the cylinder is 100cm.=1m.
