ruslelena [56]

Answer:

The probability of getting an a in both courses is 1.27

Step-by-step explanation:

Probability of getting A in Math, P(M) = 0.6 5

Probability of getting A in Science, P(S) = 0.62

Required probability of getting A in both courses, P(M and S)

= P(M) + P(S)

= 0.65 + 0.62

= 1.27

Find an equation for line perpendicular to 2x+6y=18 and goes through the point (8,-1)
bazaltina [42]

Answer:

3x +y = -2

Step-by-step explanation:

First of all, it is helpful to put the given equation in standard form. We can do that by dividing it by 2 to eliminate the common factor from the numbers.

 x -3y = 5

Next, since you want the perpendicular line, you can swap the coefficients of x and y, and negate one of them. This can give you ...

 3x +y = (some constant)

The constant will be found using the given point.

 3x +y = 3(2) +(-8) = -2 . . . the perpendicular line

An equation is ...

 3x +y = -2

HEEEEEEELLLPPPPPPPPP!!!!! PLEASEEEEEEEE
Klio2033 [76]

Answer:

a) a_n=2(a_{n-1}), where a_1=5.

b)  a_n=5(2)^{n-1}

Step-by-step explanation:

The given sequence is


5,10,20,40....


The first term of the sequence is

a_1=5


The second term is a_2=10


The common ratio for this sequence can be determined using any two consecutive terms in the sequence.

Using the first two terms, the common ratio is

r=\frac{a_2}{a_1}


\Rightarrow r=\frac{10}{5}=2


a) The recursive rule is given by,


a_n=r(a_{n-1})


a_n=2(a_{n-1}), where a_1=5.


b) The explicit rule is given by a_n=a_1r^{n-1}


\Rightarrow a_n=5(2)^{n-1}

Given point (-3,-5) and a slope of 2 write an equation in point slope form
WITCHER [35]

Answer:

\displaystyle y + 5 = 2(x + 3)

Explanation:

In the Point-Slope Formula [y - y₁ = m(x - x₁)], all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.

I am joyous to assist you anytime.
