Tyina is buying 12 shirts for the drama club. She will choose a style for the blank shirts and then pay an additional charge of

tensa zangetsu [6.8K]

Answer:

Cost of each blank shirt is less than or equal to $ 5.5

Step-by-step explanation:

Let x denotes cost of each blank shirt.

Total number fo shirts bought by Tyina = 12

Amount charged for each shirt to have the club logo = $2.75

So,

Amount charged for 12 shirts to have the club logo = $12(2.75)=\$33$

As Tyina cannot spend more than $99,

$12x+33\leq 99$

Now solve the inequality.

$12x+33\leq 99\\12x\leq 99-33\\12x\leq 66\\x\leq \frac{66}{12}\\ x\leq 5.5$

So,

Cost of each blank shirt is less than or equal to $ 5.5

On a biased dice the probability of getting 1 is 0.3. The ice is rolled 150 times. How many ones would you expect to roll?

Montano1993 [528]

Answer: 45

=====================================================

Work Shown:

n = number of rolls = 150

p = probability of rolling a "1" = 0.3

n*p = expected number of "1"s that show up out of the 150 rolls

n*p = 150*0.3

n*p = 45

We expect about 45 ones will show up.
