Answer:7,350 ways
Step-by-step explanation:
Since there is no restriction in the selection , the first thing is to select the 4 men from the 10 male , this can be done in 10 C 4 ways , which
= 210 ways
Also , we will select the 4 women from the 7 females , this can be done in 7 C 4 ways , which = 35
Altogether the team of 8 can be selected in 35 X 210 ways = 7,350 ways
Answer: Add all the numbers together which equals 55, then divide by how many numbers there are (5) so the answer is 11
Answer:
x ≈ 5.7
Step-by-step explanation:
Recall, SOH CAH TOA.
We are given:
Reference angle = 35°
Opposite side length to reference angle = 4
Adjacent side = x
To find x, apply the trigonometric equation, TOA, which is:
Tan 35° = Opp/Adj
Substitute
Tan 35° = 4/x
x*Tan 35° = 4
x = 4/Tan 35°
x ≈ 5.7
Answer:
x² +3
Step-by-step explanation:
Given these roots, two of the factors are binomials that are zero when x is one of these values:
(x -√3i), (x +√3i)
If you form the product of these factors, you get a polynomial with real, rational coefficients:
(x -√3i)(x +√3i) = x² -(√3)²(i²) = x² +3
