Answer:
18. x=(-3)
20.x=(-2)
22.x=4
Step-by-step explanation:
Answer:
1) Quartic (if asking about degree)
2) 2 terms
3) 8
4) 3x^4
5) 3
Step-by-step explanation:
1) since the degree of the polynomial is 4, it is classified as a quartic polynomial.
2) there are 2 terms (it's a binomial)
3) constant term is the term in a polynomial without a variable, in this case 8
4) leading term is the term with the highest degree throughout the whole polynomial, in this case it is 3x^4
5) leading coefficient is the coefficient to the term with the highest degree, in this case this would be regarding the term 3x^4, meanign the coefficient is the 3
It's totally okay to be confused! u got this mate :D
Answer:
D
Step-by-step explanation:
The diagram is attached.
Looking at the diagram, we want the side "opposite" of the angle given and the side "adjacent" is given.
Which ratio relates opposite and adjacent? It is Tan.
We can use trigonometry and tan ratio to solve for the distance "x":
D is the correct answer.

Answer: 26.17%
Step-by-step explanation:
Probability she scored at least 8 goals = probability that she scores 8 goals + probability that she scores 9 goals + probability that she scores 10goals.
Probability of each goal is approximated by the probability distribution formula for selection. From a larger n sample, with a varied sample r, probability is denoted by:
P(X=r) = nCr × p^r × q^n-r
Where p = probability of success = 65% = 0.65
q = 1-p = 1 - 0.65 = 0.35
n = 10
r is varied between 8, 9 and 10.
When r = 8
P(X=8) = 10C8 × 0.65^8 × 0.35² = 0.1757
When r = 9
P(X=9) = 10C9 × 0.65^9 × 0.35¹ = 0.0725
When r = 10
P(X=10) = 10C10 × 0.65^10 × 0.35^0 = 0.0135
Summation of all probabilities = 0.1757 + 0.0725 + 0.0135 = 0.2617
Probability of scoring at least 8goals = 0.2617 = 26.17%
