Suppose that 10 fair coins are tossed. Find the numbers of ways of obtaining exactly 1 heads. Round the answer to the nearest wh

Delicious77 [7]

Answer: 10

Step-by-step explanation:

Given : Total number of coins tossed = 10

Possible outcomes to toss a coin = Head or tail

Number of possible outcomes = $2^{10}=1024$

Number of ways of obtaining exactly 1 heads = ${10}C_1=\dfrac{10!}{1!9!}$ [using combinations $^nC_r=\dfrac{n!}{r!(n-r)!}$ ]

=10

Hence, the numbers of ways of obtaining exactly 1 heads= 10

A sales agent makes 40 calls a day. About 15% he calls result in a sale. How many days

Tems11 [23]

Answer: 20 days

Step-by-step explanation:

Since the sale agent makes 40 calls a day and about 15% he calls result in a sale. This means the number of sales will be:

= 15% × 40

= 0.15 × 40

= 6

6 sales out of every 40 calls per day.

The number of calls to make 120 sales will be:

= 15% of x = 120

0.15 × x = 120

0.15x = 120

x = 120/0.15

x = 800 calls

Since he needs 800 calls and he makes 40 calls per day, the number of days needed will be:

= 800/40

= 20 days

Find the perimeter?<br> Please pls

Harrizon [31]

Answer:

119 $\frac{4}{7}$

Step-by-step explanation:

10 + 12 + 15 + 24 + 12 + 10 + 35 = 118

$\frac{1}{7} + \frac{2}{7} + \frac{3}{14} + \frac{1}{14} +\frac{2}{7} + \frac{1}{7} + \frac{3}{7} = \frac{11}{7}$

118 + 1 $\frac{4}{7}$

119 + $\frac{4}{7}$

$119\frac{4}{7}$
