The answer to this question -9
Answer:
s =6
Step-by-step explanation:
40 8
--------- = ---------
30 s
Using cross products
40*s = 30*8
40s = 240
Divide each side by 40
40s/40 = 240/40
s = 6
Answer: the probability it will come up heads 25 or fewer times is 0.019
Step-by-step explanation:
Given that;
n = 50
p = 0.65
so, q = 1 - p = 0.35
np = 50 × 0.65 = 32.5 ≥ 10
nq = 50 × 0.35 = 17.5 ≥ 10
so, we need to use Normal Approximation for the Binomial Distribution
μ = np = 50 × 0.65 = 32.5
σ = √(npq) = √( 50 × 0.65 × 0.35 ) = 3.3726
now, the probability that it will come up heads 25 or few times will be;
⇒ P( x≤25)
{using continuity correction}
⇒ P[ z < (25.5 - 32.5)/3.3726 ]
⇒ P[ z < -2.0755 ]
using z-table
= 0.01923 ≈ 0.019 { 3 decimal places}
Therefore the probability it will come up heads 25 or fewer times is 0.019
Answer:
<h2>
93.4 m</h2>
Solution,
Area of rectangle = 159.1 m^2
Length of rectangle = 3.7 m
Breadth of rectangle = ?
perimeter of rectangle = ?
Now,
Area of rectangle = 159.1 m^2
or, length * breadth = 159.1
or, 3.7 * breadth = 159.1
or, 3.7 breadth = 159.1
or, breadth = 159.1 / 3.7
breadth = 43 m
Again,
Finding the perimeter of rectangle:
perimeter of rectangle:
= 2 ( length + breadth)
= 2 ( 3.7 + 43 )
= 2 * 46.7
= 93.4 m
Hope this helps...
