What is the slope of the line conaning the points (-3,4)and(2,1)

1 answer:

4 0

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ -3 &,& 4~) 
% (c,d)
&&(~ 2 &,& 1~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{1-4}{2-(-3)}\implies \cfrac{1-4}{2+3}\implies \cfrac{-3}{5}$

In the diagram, if WA = 8, AX = 5, and YA = 10, then the length of YZ is

Zinaida [17]

Answer:

Step-by-step explanation:

WA times AX = YA x YZ

8x5=40

because they have to equal each other we just have to divide 40 by 10

40/10=4 so segment YZ=4

Answer:

0.01083 or 1.083%

Step-by-step explanation:

This problem can be modeled as a binomial probability model with probability of success p = 0.56.

The probability of x=13 successes (a college student being very confident their major would lead to a good job) in a number of trials of n=15 is:

$P(X=x) = \frac{n!}{(n-x)!x!} *p^x*(1-p)^{n-x}\\P(X=13) = \frac{15!}{(15-13)!13!} *0.56^{13}*(1-0.56)^{15-13}\\P(X=13) = 0.01083=1.083\%$

The probability is 0.01083 or 1.083%.

The given trinomial can be factored using the factorization method.

x² -12x + 35
= x² -7x -5x + 35
= x(x-7) - 5(x-7)
= (x-7)(x-5)

Thus, (x-7)(x-5) is the factored form of the polynomial.

So the correct answer is option B
