Answer:
7
Step-by-step explanation:
sqrt(49)
What number times itself = 49
7*7 = 49
and
-7*-7 = 49
Given the choices choose 7
Correct option is C. He has 225 acres of land .
Let the Number of acres of land Roy have = x
As he planted corn on 1/5 of his land,
Number of acres of his land planted with corn = 1/5 × Number of acres of land Roy have
= x/5
As he planted 45 acres of his land with corn,
⇒ x/5
= 45
⇒x = 45 × 5
⇒x = 225
Therefore, number of acres of land Roy have is 225 .

b) μ = 2 and σ = 1.29
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>
<em>Given that the probability of labelled '1'</em>
<em> </em>
=0.16
<em> q = 1-p = 1- 0.16 = 0.84</em>
Let 'X' be a random variable in binomial distribution
The mean of the binomial distribution
μ = n p
μ =
<em>The mean of the binomial distribution = 2</em>
