Answer:

Height = 5.6cm

Step-by-step explanation:

Area = 1/2bh

b = 10cm, area = 28cm^2

:- 28 = 1/2 × (10)h

28 = 5h

h = 28/5

h = 5.6cm

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p

strojnjashka [21]

Answer:

P(X = 3) = 0.14680064

Step-by-step explanation:

Formula=============================

$p\left( X=k\right) =C^{k}_{n}p^{k}(1-p)^{n-k}\ \ ;\ k\in \left\{ 0,\ldots ,n\right\}$

……………………………………………………………………..

Given :

n = 8

p = 0.2

1 - p = 1 - 0.2 = 0.8

k = 3

Then

$p\left( X=3\right) =C^{3}_{8}(0.2)^{3}(0.8)^{5}$

$=0.14680064$

$=2 \sqrt 7 - \sqrt{4 \cdot 7}$

$=2 \sqrt 7 - \sqrt{4} \cdot \sqrt{7}$

$=2 \sqrt7 - 2 \sqrt 7$

$=0$

Find an equation in point-slope form for the line having the slope m= -5 and containing the point (7,2).

Juli2301 [7.4K]

Answer:

y - 2 = - 5(x - 7)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 5 and (a, b) = (7, 2) , thus

y - 2 = - 5(x - 7) ← equation in point- slope form
