The height of the track will be given by:
sin θ=opposite/ hypotenuse
θ=34°4'=34+4/60=34 1/15°
thus
sin 34 1/15=h/68.8
h=68.8sin 34 1/15
h=38.54 meters
Answer:
C, D and E
Step-by-step explanation:
Given
Represent solid beads with S and clear beads with C
So:
Required
Select operations that give an equivalent ratio
First, we need to get the unit ratio
Divide through by 4
-- This means that, after any operation. The equivalent ratio must be 2: 5
Option A: Add 2 to S and 2 to C
Perform the operation
Divide through by 2
Option B: Subtract 8 from S and 6 from C
Perform the operation
Option C: Multiply S and C by 2
Perform the operation
Divide through by 8
Option D: Divide S and C by 4
Perform the operation
Option E: Multiply S and C by 18
Perform the operation
Divide through by 72
<em>From the calculations above, options C, D and E gave an equivalent of 2:5.</em>
Two and five-tenths plus 13 and five-tenths times ten
and the answer is 160

Answer:
X is a binomial random variable
Then the condition is met
Step-by-step explanation:
Sample size n₁ = 400
X represents the number of brand-name lightbulbs)
P(X) = 44/400
P(X) = 0,11
X is a binomial random variable it only could be either no defective or defective ( only two conditions or values).
To make use of the condition of approximation of binomial distribution to a normal distribution it is required that the products:
p*n = 0,11*400 = 44 and q = 1 - 0,11 q = 0,89
q*n = 0,89 * 400 = 356
both p*n q*n are greater than 5.
Then the condition is met
