Louis brings 79 pencils to school. After he gives each of his 15 classmates an equal number of pencils, he will give any leftove
slavikrds [6]

Answer:

a. 4\ pencils

b. His teacher will receive more pencils (See explanation).

Step-by-step explanation:

a. The total number of pencils Louis brings to school is:

total\ pencils=79

Then, in order to calculate the number of pencils Louis’s teacher will receive after he gives each of his 15 classmates an equal number of pencils, you need to solve the division show in the picture attached.

Notice that the remainder obtained is: 4.

<em>This means that Louis’s teacher will receive 4 pencils.</em>

b. If Louis decides instead to take an equal share of the pencils along with his classmates, his teacher will receive more pencils; because the amount of pencils each classmate will receive will be less. This means that the number of pencils leftover will increase, leaving more pencils for his teacher.

Pavlova-9 [17]

Answer:

Mean = 3.4

Variance = 1.088

Standard deviation = 1.0431

Step-by-step explanation:

P=0.68\\ \\N=5

The mean of a binomial distribution with parameters N (the number of trials) and p (the probability of success for each trial) is m=N\cdot p

Thus,

m=5\cdot 0.68=3.4

The variance of the binomial distribution is s^2=Np(1-p), where s^2​​ is the variance of the binomial distribution, so

s^2=5\cdot 0.68\cdot (1-0.68)=3.4\cdot 0.32=1.088

The standard deviation s is the square root of the variance s^2, so

s=\sqrt{1.088}\approx 1.0431

In the figure, two parallel lines are cut by two other parallel lines. The measure of one of the angles is labeled. Find the mea
11111nata11111 [884]

Answer:

The measure of the angles are

m∠1=128°

m∠2=52°

m∠3=52°

m∠4=128°

m∠5=128°

m∠6=128°

m∠7=52°

m∠8=52°

Step-by-step explanation:

see the attached figure with numbers to better understand the problem

step 1

Find the measure of angle 5  

we know that

m∠5+52°=180° ----> by consecutive interior angles

m∠5=180°-52°=128°

step 2

Find the measure of angle 8

we know that

m∠8=52° ----> by vertical angles

step 3  

Find the measure of angle 7

we know that

m∠7=m∠8 ----> by corresponding angles

we have

m∠8=52°

therefore

m∠7=52°

step 4

Find the measure of angle 6

we know that

m∠6+m∠7=180° ----> by supplementary angles

we have

m∠7=52°

therefore

m∠6+52°=180°

m∠6=180°-52°=128°

step 5

Find the measure of angle 3

we know that

m∠3+m∠6=180° ----> by consecutive interior angles

we have

m∠6=128°

m∠3=180°-128°=52°

step 6

Find the measure of angle 2

we know that

m∠2=m∠3 ----> by vertical angles

we have

m∠3=52°

therefore

m∠2=52°

step 7

Find the measure of angle 1

we know that

m∠1+m∠3=180° ----> by supplementary angles

we have

m∠3=52°

therefore

m∠1+52°=180°

m∠1=180°-52°=128°

step 8

Find the measure of angle 4

we know that

m∠4=m∠1 ----> by vertical angles

we have

m∠1=128°

therefore

m∠4=128°

I need this answer please
julsineya [31]

Answer:

3a+6b = 45

Multiply by 2

6a +12b = 90.....(1)

2a- 2b = -12

Multiply by 3

6a - 6b = -36 .....(2)

(1)-(2)

18b = 126

b= 7

3a+6b = 45

3a + 6(7) = 45

3a +42 = 45

3a = 3

a= 1

(a,b) = ( 1,7)
