7. The probability that a randomly chosen student will be left-handed is .09: a) In a class of 108, find the probability that there will be (exactly) 8 left-handed students. b) The classroom has 12 desks designed for people who are left-handed. Use an appropriate approximate method to find the probability that there are enough for all the left-handed students.

### Answers

**Solution :**

Let x be student will be left handed

P = 0.09

Using the normal approximation to binomial distribution,

a). n = 108,

μ = np = 9.72

[tex]$\sigma = \sqrt{np(1-p)}$[/tex]

[tex]$=\sqrt{8.8452}$[/tex]

= 2.9741

Required probability,

P(x=8) = P(7.5 < x < 8.5)

[tex]$=P\left(\frac{7.5-9.72}{2.9741}< \frac{x-\mu}{\sigma}< \frac{8.5-9.72}{2.9741}\right)$[/tex]

[tex]$=P(-0.75 < z < -0.41)$[/tex]

Using z table,

= P(z<-0.41)-P(z<-0.75)

= 0.3409-0.2266

= 0.1143

b). P(x=12) = P(11.5 < x < 12.5)

[tex]$=P\left(\frac{11.5-9.72}{2.9741}< \frac{x-\mu}{\sigma}< \frac{12.5-9.72}{2.9741}\right)$[/tex]

[tex]$=P(0.60 < z < 0.94)$[/tex]

Using z table,

= P(z< 0.94)-P(z< 0.60)

= 0.8294 - 0.7257

= 0.1006

**Step-by-step explanation:**

since they are both outside or just exterior, and they are the opposite, so alternate exterior angles

m∠1=(3x+21)° and m∠3=(4x+9)° what is the value of x

### Answers

Value of [tex]x[/tex] as per considering given pair as** vertical opposite angles** is equals to [tex]12[/tex] degrees.

What are vertical opposite angles?

"** Vertical opposite angles **are defined as when two straight line intersect each other , the two non adjacent angles are vertical opposite angles. Measure of vertical opposite angles are always equal."

According to the question,

Given measure of **angles**,

[tex]m \angle1 = (3x + 21)\°[/tex]

[tex]m \angle3= (4x + 9)\°[/tex]

Consider both the angles as **vertically opposite angles** we get,

[tex]m \angle1 =m \angle3 \\\implies(3x + 21)\° = (4x + 9)\°\\\\\implies 4x -3x = (21 - 9))\°\\\\\implies x = 12\°[/tex]

Hence, **value** of [tex]x[/tex] as per considering given pair as** vertical opposite angles** is equals to [tex]12[/tex] degrees.

Marcie Ann Weber, age 32, takes out $15,000 of a term insurance for a ten year term.

annual premium: $

quarterly premium: $

### Answers

**Answer:**

Annual premium = $1,500 per year

Quarterly premium = $375 per quarter

**Step-by-step explanation:**

**Given:**

Insured amount of term insurance plan = $15,000

Number of year = 10 year

**Find:**

Annual premium

Quarterly premium

**Computation:**

Annual premium = Insured amount of term insurance plan / Number of year

Annual premium = $15,000 / 10

**Annual premium = $1,500 per year**

Quarterly premium = Insured amount of term insurance plan / Number of quarter in 10 year

Quarterly premium = 15,000 / (10 x 4)

Quarterly premium = 15,000 / 40

**Quarterly premium = $375 per quarter**

Find the value of X and Y that make these triangles congruent by the HL theorem.

### Answers

**Answer:**

x=5, y=6

**Step-by-step explanation:**

By the HL theorem, if the corresponding hypotenuses and one side of two triangles are equal, they are congruent.

So put the hypotenuses equal to each other, and put the side lengths equal to each other.

3x-2=2y+1

x=y-1

Sub 'y-1' into the first equation for x:

3(y-1)-2=2y+1

3y-3-2=2y+1

y=6

x=y-1=6-1=5
