Answer:

Q1. Option B

Q2. x>3

Q3. 62°

Q4. First three options are correct

Step-by-step explanation:

Q1. Solving the given options one by one. We get,

A. -1/4(y-1/2) = -1/4y + 1/8

B. 1/4(y-2) = 1/4y - 1/2

C. 1/4(y−1/2) = 1/4y - 1/8

D.−1/4(y−2) = -1/4y + 1/2

So, Option B is correct answer.

Q2. Solving the given equation,

5.5x+15.5>32

5.5x + 15.5 -15.5 > 32 -15.5

5.5x > 16.5

x > 3

Q3. Here, The third quadrant is of 90°

So, x = 90° - 28° = 62°

Q4. Since 3% of d = 0.03d

Also, Money given by bank + Money given by his grandmother

= 0.03d + 0.03d = 0.06d

So, total amount of money he get ater one year is d + 0.06d =1.06d

Hence, First three options are correct as 1.06d = d+0.06d = d+0.03d+0.03d

1 is B.
2 is x > 3
4 is d+0.06d

I don't know 3, but I'll ask it for you, since you don't have many points.

Find the area of a sector with a central angle of 120° and a diameter of 7.3 cm. Round to the nearest tenth.

Andru [333]

Answer: $14cm^{2}$

Step-by-step explanation:

diameter=7.3cm

radius= $\frac{diameter}{2}$

= $\frac{7.3}{2}$

=3.65cm

angle =120°

area= $\frac{angle (tita)}{360}$ × $\frac{\pi r^{2} }{1}$

= $\frac{120}{360}$ × $\frac{22}{7}$ × $3.65^{2}$

= $13.95cm^{2}$

≅ $14cm^{2}$

Chapter 6, Section 1-D, Exercise 009 Is a Normal Distribution Appropriate? In each case below, is the sample size large enough s

Xelga [282]

Answer:

Step-by-step explanation:

Complete Question:

Chapter 6, Section 1-D, Exercise 009 Is a Normal Distribution Appropriate? In each case below, is the sample size large enough so that the sample proportions follow a normal distribution?

a) n=600 p=0.2

b) n=20, p=0.4

if np=10 and npq=10 then the data follows normal distribution

a) np= 120,

q= 1-0.2= 0.8

npq= 600 ×0.2×0.4 = 48

Normal distribution is appropriate and sample size is large enough

b) np= 8

q= 1-0.4= 0.6

npq= 20 × 0.4×0.6= 4.8

sample size is not large enough so normal distribution is not appropriate.

2/3xd=10/9 what is d

lisabon 2012 [21]

Answer:d=5/3x

Step-by-step explanation:

Let's solve for d.

(2/3x)(d)=10/9

Step 1: Divide both sides by (2x)/3.

2/3dx / 2x/3=10/9 / 2x/3

d=5/3x
