Answer:

x = 11

Step-by-step explanation:

The two angles form a straight line so they add to 180

4x+15 + 11x = 180

Combine like terms

15x+15 = 180

Subtract 15 from each side

15x+15-15 = 180-15

15x = 165

Divide by 15

15x/15 =165/15

x = 11

The probability of getting a head when a biased coin is tossed is . The coin is tossed three times. Find the following probabili

S_A_V [24]

Answer:

a) P(three tails) = $\frac{1}{8}$

b) P(two tails followed by one head) = $\frac{1}{8}$

Step-by-step explanation:

coin is tossed three times so, outcome is

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

Hence sample space will be

S = {HHH, TTT, HTH, THH, HHT, THT, TTH, HTT}

chance of getting three tails is '1' i.e. TTT

hence,

P(three tails) = $\frac{1}{8}$

two tails followed by one head is TTH

so, chance of getting that outcome is also '1'

hence,

P(two tails followed by one head) = $\frac{1}{8}$

Which sample fairly represents the population? Select two options.

ExtremeBDS [4]

Answer:

b) observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses.

d) taking a poll in the lunch room (where all students currently have to eat lunch) to determine the number of students who want to be able to leave campus during lunch.

Step-by-step explanation:

These are the two options that are most likely to give you a sample that fairly represents the population. In the first case, the sample that you obtain is likely to be a good representation because Main Street is a road where a great variety of people walk. Moreover, 5 pm is also a time that will allow you to see a great number of different people. The second answer will also give you a good sample, as the poll would include all students in the lunch room, which is all students in the school (the whole population).

Hey you!!!! <br> Help me please

Answer:

If the population has increased by 12% then to ensure a generated maximum capacity must be more than 12% we already have a figure being 100% prior so the answer is 12% population increase =112% and 12%.of 112 =13.44

We add this to 12

12+13.44= 25.44

Your family went to a pancake house for breakfast and spent $34 your family decides to leave at 18% tip how much is the tip? Wha

NikAS [45]

Answer:

$40.12.

Step-by-step explanation:

We have been given that your family went to a pancake house for breakfast and spent $34 your family decides to leave at 18% tip how much is the tip. We are asked to find the total amount of bill with the tip.

The total amount of bill with the tip will be cost of breakfast plus 18% of cost of breakfast.

$\text{The total amount of bill with the tip}=\$34+\$34\times \frac{18}{100}$

$\text{The total amount of bill with the tip}=\$34+\$34\times 0.18$

$\text{The total amount of bill with the tip}=\$34+\$6.12$

$\text{The total amount of bill with the tip}=\$40.12$

Therefore, the total amount of the bill will the tip would be $40.12.
