The Art Club wants to paint a rectangle-shaped mural to celebrate the winners of the track and field meet. They design a checker
valentina_108 [34]

Answer:

72 inches

Step-by-step explanation:

We are given that

Length of rectangle=423 inches

Width of rectangle=360 inches

We have to find the side length of the largest square they can use to fill the checkboard pattern completely without overlap or gaps with the help of Euclid's algorithm.

In order to find the largest side of square we will find HCF (432,360).

Euclid's algorithm

a=bq+r

a=dividend

b=divisor

q=quotient

r=remainder

a=432,b=360

432=360\times 1+72

360=72\times 5+0

HCF(432,360)=72

Hence, the side of largest square=72  inches

Food allergies affect an estimated 7% of children under age 5 in the US. What is the probability that in a kindergarden class of
bezimeni [28]

Answer:

Probability of atleast one of 12 student has food allergies ≈ 0.58 ( approx)

Step-by-step explanation:

Given: Probability of a children under age 5 has food allergies = 7%

                                                                                                        =\frac{7}{100}

To find : Probability of atleast one of 12 student has food allergies

Probability of a chindren under age 5 does not have food allergies = 1-\frac{7}{100}

                  ⇒ prob = \frac{93}{100}

now we find Probability of atleast one of 12 student has food allergies this means we have to find prob of 1 student, 2 student, 3 student, till 12 student have allergy out of 12 student of class then add all prob.

But instead of finding all these probability we find probability of student having no allergy.i.e., 0 student then subtract it from 1(total probability)

Probability of 0 student having allergy out of 12 student = (\frac{93}{100})^{12}

Therefore, Probability of atleast one of 12 student has food allergies

                  = 1-(\frac{93}{100})^{12}

                  = 0.581403702521

                  ≈ 0.58 ( approx)

Solve the inequality algebraically. Write the solution in interval notation.<br> |9x + 10| &lt; 15
viva [34]

The given inequality is

| 9x+ 10 |

First we need to remove the absolute sign , and when we do so , we will get a compound inequality, that is

-15< 9x+10 < 15

To solve for x, first we need to get rid of 10. and for that, we have to do subtraction

-15-10

Now we need to get rid of 9, and for that, we do division

\frac{-25}{9}< x< \frac{5}{9}

So the required solution is

( \frac{-25}{9} , \frac{5}{9})
