3(s-5)/4 -3 = 4s- (s-3)/2 pls answer fast

Jobisdone [24]

Answer:

$s = \frac{9± \sqrt{ - 39} }{4}$

Step-by-step explanation:

$\frac{3(s - 5)}{4 - 3} = \frac{4s \times (s - 3)}{2}$

➡️ $\frac{3(s - 5)}{1} = 2s \times (s - 3)$

➡️ $3s - 15 = 2 {s}^{2} - 6s$

➡️ $3s - 15 - 2 {s}^{2} + 6s = 0$

➡️ $9s - 15 - 2 {s}^{2} = 0$

➡️ $- 2 {s}^{2} + 9s - 15 = 0$

➡️ $2 {s}^{2} - 9s + 15 = 0$

➡️ $s = \frac{ - ( - 9)± \sqrt{( - 9 {)}^{2} - 4 \times 2 \times 15} }{2 \times 2}$

➡️ $s = \frac{9± \sqrt{81 - 120} }{4}$

➡️ $s = \frac{9± \sqrt{ - 39} }{4}$

➡️ $s∉ℝ$

Determine whether the events E and F are independent or dependent. Justify your answer. (a) E: A person living at least 70 yea

Gnoma [55]

Answer:

a) E & F are dependent because regularly handling venomous snakes can affect the probability of a person living at least 70 years.

Step-by-step explanation:

Independent Events. When two events are said to be independent of each other, what this means is that the probability that one event occurs in no way affects the probability of the other event occurring.

Two events are dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed.

Since Venomous snakes are species of the suborder Serpents that are capable of producing venom, which they use for killing prey, for defense, and to assist with digestion of their prey and the older you get the less active you become, Hence the handle of venomous snakes can affect the probability of a person living at least 70 years

What are the values of x and y x=9/4 y=3/4 x=9/4 y=15/4 x=15/4 y=5/4 x=3/4 y=15/4

laiz [17]

The complete question in the attached figure

we know that

in the triangle BDC
cos alfa=3/y----------> equation 1
sin alfa=x/y----------> equation 2

in the triangle ABD
cos alfa=4/5--------> equation 3
sin alfa=3/5---------> equation 4

then

Equal equation 1 and 3
3/y=4/5---------> y/3=5/4----------> y=15/4

Equal equation 2 and 4
x/y=3/5-------> x=3*y/5------------> 3*15/(4*5)-----> x=9/4

the answer is
x=9/4 y=15/4
