A1 = 5
d = a2-a1 = 2-5 = -3

a(n) = a + (n - 1)d \\ a(n) = 5 + (n -1) - 3 \\ a(n) = 5 - 3(n - 1)

The parallelogram shown below has an area of 35 units^2 2 squared. Find the missing height. h =h=h, equals units
Anit [1.1K]

Answer:

h = 5 units

Step-by-step explanation:

Given that,

The area of the parallelogram, A = 35 unit²

In the attached figure, we can see that the base is 7 unit.

We know that,

Area of a parallelogram, A = b × h

So,

h=\dfrac{A}{b}\\\\h=\dfrac{35}{7}\\\\h=5\ units

So, the value of h is equal to 5 units.

strojnjashka [21]

Answer:

Standard deviation = 0.547

Step-by-step explanation:

Given the data

$5 for spade

$10 for any club

$20 for an ace club

Lets assume Probability of getting these cards to be

0.5, 0.20 and 0.30

Therefore, mean would be

Summation (PX) = 5×0.5 + 10×0.2 +20×0.3

Summation (PX)/n= 10.5/35 = 0.3

Standard deviation = √0.3

Standard deviation = 0.547
