Answer:

a) 32100 millimeters

c) 3,210 centimeters

d)3.21 decameters

Step-by-step explanation:

To find which measurements are equal 321 decimeters, we will follow the steps below:

changing 321 decimeters to millimeters

let x be 321 decimeters in millimeters

1 decimeter = 100 millimeters

321 decimeters = x

cross - multiply

x = 321× 100

x = 32100 millimeters

hence, 321 decimeters = 32100 millimeters

converting 321 decimeters to centimeters

let y be 321 decimeters in centimeters

1 decimeters = 10 centimeters

321 decimeters = y

cross-multiply

y = 321× 10

y = 3210 centimeters

Thus, 321 decimeters = 3210 centimeters

converting decimeter to decameters

let z represent 321 decimeters in decameters

1 decameter = 100 decimeter

z = 321 decimeter

cross-multiply

100 z = 321

divide both-side by 100

100z/100 = 321/100

z=3.21 decameters

therefore, 321 decimeters = 3.21 decameters

In aâ€‹ lottery, 6 numbers are randomly sampled without replacement from the integers 1 to 50. Their order of selection is not i

nlexa [21]

Answer: 0.444225

Step-by-step explanation:

Given : The total number of tickets = 50

Number of tickets are randomly sampled without replacement =6

Since the order of selection is not important , so we use combinations.

Total number of ways to select 6 tickets = $^{50}C_6$

The number of winning tickets = 6

So, number of tickets that are not winning = 50-6=44

Number of ways of selecting zero winning numbers= $^{44}C_{6}$

Now , the probability of holding a ticket that has zero winning numbers out of the 6 numbers selected for the winning ticket out of the 50 possible numbers would be $\dfrac{^{44}C_{6}}{^{50}C_6}$

$=\dfrac{\dfrac{44!}{6!(44-6)!}}{\dfrac{50!}{6!(50-6)!}}\\\\\\=\dfrac{\dfrac{44\times43\times42\times41\times40\times39\times38!}{38!}}{\dfrac{50\times49\times48\times47\times46\times45\times44!}{44!}}\\\\\\=\dfrac{44\times43\times42\times41\times40\times39}{50\times49\times48\times47\times46\times45}\\\\=\dfrac{252109}{567525}\approx0.444225$

Hence, the required probability = 0.444225

I’m guessing you want to find out (n).
That’s what I did anyway.

The answer is: n=5

Step 1: Subtract 5n from both sides.

Evaluate the following expressions for a = -3,b=2,c=5

Ksju [112]

Hey!

----------------------------------------------------------------------

We know that (a = -3), (b = 2), (c = 5), and (d = -4).

----------------------------------------------------------------------

Solution #1:

$=\frac{a-4b}{3c+2d}$

$=\frac{(-3) - 4(2)}{3(5) + 2(-4)}$

$=\frac{(-3) - 8}{15 +( -8)}$

$=\frac{-11}{7}$

≈ 1.57

----------------------------------------------------------------------

Solution #2:

= a - 4b / 3c + 2d

= (-3) - 4(2) / 3(5) + 2(-4)

= (-3) - 8 / 15 + (-8)

= (-3) - 0.53 + (-8)

= (-3.53) + (-8)

= -11.53

----------------------------------------------------------------------

Solution #1 Answer: 1.57

Solution #2 Answer: -11.53
