A coin is tossed 3 times. What is the probability that the number of tails obtained will be between 1 and 3 inclusive?

LekaFEV [45]

Answer: $\dfrac{7}{8}$

Step-by-step explanation:

Given : When a coin is tossed twice , the total outcomes will become

HHH , HHT , HTH , THH , TTH , THT , HTT ,TTT

Total outcomes = 8

Favorable outcomes to obtain 1 and 3 inclusive = HHT , HTH , THH , TTH , THT , HTT ,TTT

Number of favorable outcomes = 7

Probability that the number of tails obtained will be between 1 and 3 inclusive = $\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

$=\dfrac{7}{8}$

Hence, the probability that the number of tails obtained will be between 1 and 3 inclusive $=\dfrac{7}{8}$

(7,9) has a slope of 1. Write equation in slope intercept form

Nadya [2.5K]

Step-by-step explanation:

Here, slope of the line (m) = 1

Here, slope of the line (m) = 1And, the line passes through the point (7,9)

Equation of the line is given by 

y - y1 = m ( x - x1 )

y - 9 = 1( x - 7)

y - 9 = x -7

x -7+9-y = 0

x - y + 2 = 0 

 is the required equation of the line.

Find the unit rate. Enter your answer as a mixed number.

lesya [120]

The unit rate is the change of a quantity over one unit of another thus the unit rate of fertilizer covers is (30/8) foot per hour.

<h3>What is the rate of change?</h3>

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given,

A fertilizer covers 5/8 square feet in 1/6 hour.

5/8 square feet ⇒ 1/6 hour

Multiply both sides by 6

6 × 5/8 square feet ⇒ 6/6 hour

30/8 square feet ⇒ 1 hour.

Hence "The unit rate is the change of a quantity over one unit of another thus the unit rate of fertilizer covers is (30/8) foot per hour".
