Answer:

119

Step-by-step explanation:

Find 10% by dividing by 10, then halve it to get 5%. The answers are 14 and 7 accordingly.

Add them together to get 15%, which is now 21.

Take 21 off of 140 to get the answer, which is 119.

ALTERNATIVE METHOD - CALCULATOR

To solve the question using a calculator and with only one equation, multiply the number by 0.85 to find 85% of the number, and there's your answer.

<span>Winning Probablity = 0.2, hence Losing Probability = 0.8 Probablity of winning atmost one time, that means win one and lose four times or lose all the times. So p(W1 or W0) = p (W1) + p(W0) Winning once W1 is equal to L4, winning zero times is losing 5 times. p(W1) = p(W1&L4) and this happens 5 times; p(W0) = p(L5); p (W1) + p(W0) = p(L4) + p(L5) p(L4) + p(L5) = (5 x 0.2 x 0.8^4) + (0.8^5) => 0.8^4 + 0.8^5 p(W1 or W0) = 0.4096 + 0.32768 = 0.7373</span>

Find the slope of the line y = -7/6x - 8/3.
Nezavi [6.7K]

Hello!

This equation is written in slope-intercept form.

Slope-intercept form is y = mx + b, where m is the slope and y is the y-intercept.

Since the coefficient -7/6 is multiplied with x, the slope (or m) has to equal to -7/6.

Therefore, the slope of the line is -7/6.

Multiply. <br> 8 1/2 -2 2/3
MrRissso [65]

Answer: -\frac{68}{3} or -22\ 2/3

Step-by-step explanation:

To solve this problem you must:

- Convert the mixed numbers to fractions, as following:

8\ 1/2=\frac{((8*2)+1)}{2}=\frac{17}{2}

2\ 2/3=\frac{((3(2)+2)}{3}=\frac{8}{3}

- Multiply both fractions. Mutilply the numerators and the denominators:

(\frac{17}{2})(-\frac{8}{3})=-\frac{136}{6}

- Simplify. Therefore, you obtain that the answer is:

-\frac{68}{3} or -22\ 2/3
