Answer:

In the Pythagorean Theorem, a right triangles hypotenuse is found by a^2 +b^2= c^2. The distance formula is basically the same thing. With two points, a right triangle can be formed and the slop would be the hypotenuse. That's where the distance formula comes from

Is a triangle with the angles 60 degrees, 40 degrees, and 80 degrees unique?

oksano4ka [1.4K]

No a triangle with these angles are not unique. This is because every triangle is supposed to have 180 degrees, just like this one.

Have a great day!

If vector u = <-3.5, -1.5> and vector v = <-1.25, 2.25>, which graph shows the resulting vector for 2v − u?

Sedaia [141]

Answer:

Step-by-step explanation:

We know that vector addition is scalar addition.

Given vectors are u = <-3.5, -1.5> and v = <-1.25, 2.25>

2v = < -2.5, 4.5>

2v - u = < -2.5, 4.5> - <-3.5, -1.5> = < -2.5 - (-3.5) , 4.5 -(-1.5) >

2v-u = < 1 , 6 >

This vector is basically i + 6j which is drawn in option D

Suppose that 20° of boys opted for mathematics and 40% of girls opted for mathematics. What is the probability that a student op

ankoles [38]

Answer: 30%

Step-by-step explanation:

Let A be the probability of a student opting for mathematics - it consists of either boy opting for mathematics or girl opting for mathematics. As there is "or" we need to sum these probabilities.

$P(A) = P(B)* P(M|G) + P(G)*P(M|G)$

$P(A) = \frac{1}{2} * \frac{20}{100} + \frac{1}{2} * \frac{40}{100}$

$P(A) = 3/10 = 0.3$

=> 30%

Find the mean of this data set: {– 78, -12, 3, – 44}

blagie [28]

Answer:

Answer: A. -32.75

$\dashrightarrow{ \tt{mean = \frac{ \sum f(n)}{n} }} \\$

• f(n) are the values of the set

• n is the number of items

$\dashrightarrow \: { \tt{mean = \frac{ - 78 + ( - 12) + 3 + ( - 44)}{4} }} \\ \\ \dashrightarrow \: { \tt{ \frac{ - 131}{4} }} \\ \\ \dashrightarrow \: { \boxed{ \tt{mean = - 32.75}}}$
