In equilateral △ABC, y = ?

Nina [5.8K]

Well since it’s equilateral then we know that x+3x+2x=180/3=6
So 6x=6 x=6
Angle ACB is gonna be 60 degrees (bc it’s equilateral)
So we can do 3x+2x+60+y=180
So we have 3+2+60+y=180
So y will equal 115

Can I also have brainliest?

Help me please for my final

Vadim26 [7]

Answer:

Equation of line l,

3x-4y=1/2

y=3/4x-1/2

we get,

slope of line l =3/4

Equation of line m,

x-5=2y

y=1/2-5/2

Hence slope of line m=1/2

Slope of line l is not equal to slope of line m. Hence the line are not parallel.

Slope of line l* slope of line m ,

(3/4)*(1/2) =3/8

Since the product of slope of line l and the slope of line m is not equal to -1, the lines are not perpendicular.

Hence the lines are neither perpendicular nor parallel..

6^3=216. Using exponents, write three more expressions whose value is 216.

faltersainse [42]

Answer:

$216^1$

$(2^3)(3^3)$

$(2*2^2)(3*3^2)$

Step-by-step explanation:

To solve this exercise you must keep on mind that according to the exponents rules:

$(a^m)(a^n)=a^{(m+n)}$

$a^1=a$

1) Therefore, you can write 216 as:

$216^1$

Because: $216^1=216$

2) Descompose the number 216 into its prime factors, then:

$216=2*2*2*3*3*3=(2^3)(3^3)$

Then you can write the number 216 as $(2^3)(3^3)$

3) You can also write 216 as following:

$(2*2^2)(3*3^2)$

Stephen Curry's Free Throws As we see in Exercise P.37, during the 2015-16 NBA season, Stephen Curry of the Golden State Warrior

Reil [10]

Answer:

A) $P(X=x) = \binom{2}{x}.(0.908)^x.(0.092)^{2-x}$

B) Mean = 1.816

Step-by-step explanation:

We are given the following information:

We treat Stephen Curry making any given free throw as a success.

P(Stephen Curry makes any given free throw) = 0.908

Since the probability for the free throw is equal for each trial and free throws are independent.

Then the number of free shots follows a binomial distribution.

A) Probability distribution

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Here n = 2, p = 0.908

$P(X=x) = \binom{2}{x}.(0.908)^x.(1-0.908)^{2-x}\\\\P(X=x) = \binom{2}{x}.(0.908)^x.(0.092)^{2-x}$

Now x can take values 0, 1 , 2

Putting values, we get,

$P(x = 0) = 0.008464\\P(x = 1) = 0.167072\\P(x = 2) = 0.82446$

B) Mean of X

$\mu = np = 2(0.908) =1.816$

Thus, the mean number of free shots made by Stephen Curry is 1.816
