HELP!!!! ASAP

Mathematics
1 answer:
MakcuM [25]3 years ago
6 0

Answer:

B

Step-by-step explanation:

First, put 3(sqrt(6)) in a different form:

sqrt(9) * sqrt(6) = sqrt(54)

We know that a 30 60 90 triangle has a horizontal leg equal to 1, a vertical leg equal to sqrt(3), and a hypotenuse equal to 2.

Find a multiplier/ratio with this information:

(sqrt(54))/(sqrt(3)) = sqrt(18)

given value/accepted value = multiplier

Now, multiply the other values by the multiplier:

1*sqrt(18) = sqrt(18) or 3(sqrt(2))

2*sqrt(18) = 2(sqrt(18)) or 6(sqrt(2))

Your answer would be:

x = 3(sqrt(2))

y = 6(sqrt(2))

Or option B.

bekas [8.4K]

Kindly note that the question says 4; maybe the final question was intended to be the probability that he gets exactly 2 of the 4 correct. However. If it is the other way round. This a e procedure used in the solution should also be followed.

Answer:

0.21

Step-by-step explanation:

Number of options = 4

One correct answer per option ; hence, the probability of success, p = 1/4 = 0.25

Using the binomial probability relation :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

x = 2 ; n = 4

p = 0.25 ; 1 - p = 0.75

P(x = 2) = 4C2 * 0.25^2 * 0.75^2

P(x = 2) = 6 * 0.0625 * 0.5625

P(x = 2) = 0.2109375

P(x = 2) = 0.21 (2 decimal places)

Note : if the question was 3, then put, n = 3 instead of 4

What is the slope of the line shown below? (-2,3) (-4,-9)
kodGreya [7K]

Answer:

<h2>6</h2>

Step-by-step explanation:

Let the points be A and B

A ( - 2 , 3 ) -------> ( x1 , x2 )

B ( -4 , -9 ) -------> ( x2 , y2 )

Now, finding the slope:

slope \: (m) =  \frac{y2 - y1}{x2 - x1}

Plug the values

=  \frac{ - 9 - 3}{ - 4 - ( - 2)}

Calculate

=  \frac{ - 12}{ - 4 - ( - 2)}

When there is a (-) in front of an expression in parentheses , change the sign of each term in expression

=  \frac{ - 12}{ - 4 + 2}

Calculate

=  \frac{ - 12}{ - 2}

Reduce the fraction with -2

= 6

Hope this helps..

Best regards!!
