The number of people who grow potatoes is 3 times the number that grow sugar beet.
⇒ 48 + x = 3( x + 12)

--------------------------------------------
Solve for x :
--------------------------------------------
48 + x = 3( x + 12)
48 + x = 3x + 36
2x = 12
x = 6

--------------------------------------------
People who do both grow either.
--------------------------------------------

Number of people who does not grow potato or sugar beets = 100 - 48 - 12 - 6 = 34

------------------------------------------------------------------------------
Answer: The answers are 6 and 34.
------------------------------------------------------------------------------
"6" is inbetween "48" and "12".
"34" is outside the two circles.

A survey was conducted by an independent price checking company to check an advertiser's claim that it had lower prices than its

Mama L [17]

Answer:

a) critical values ≈ -3.182 and 3.182 shows that there is difference in average prices

b) H0 : μd = 0

Ha : μd ≠ 0

Step-by-step explanation:

<u>a) Determine if there is any significant difference in the average prices </u>

using ∝ = 0.05

and μ( advertiser ) - μ ( competitor ) = μd

test statistic ( t ) = -3.011

df = 3

hence the critical values ( two tailed test ) = -3.182 and 3.182. this shows that there is sufficient evidence to show that there is difference in the average prices

<u>b) state the hypothesis</u>

H0 : μd = 0 ( null )

Alternate hypothesis : Ha : μd ≠ 0

the length of a rectangle is 2ft more than twice the width. The area is 180 ft^2. find the length and width of the rectangle

Mariana [72]

Answer:

Area = length * width

112 = (2w+2)*w

112 = 2w^2 + 2w

0 =2w^2 + 2w - 112

0 = w^2 + w - 56

0 = ( w + 8 )( w - 7 )

w+8=0 results in negative measures

w-7=0 --> w = 7

width is 7

length is 16

9. A computer chip manufacturer knows that 72% of the chips produced are defective.

adoni [48]

The probability that exactly 800 chips are acceptable is less than 0.000001

<h3>How to determine the probability?</h3>

The given parameters are:

Sample, n = 3000
Percentage acceptable, p = 72%
Acceptable chips, x = 800

The binomial probability is represented as:

$P(x) = ^nC_x * p^x * (1- p)^{n - x}$

So, we have:

$P(300) = ^{3000}C_{800} * (72\%)^{800} * (1- 72\%)^{3000 - 800}$

The data values are large.

So, we use a statistical calculator to evaluate the expression

Using the calculator, we have:

P(300) < 0.000001

Hence, the probability that exactly 800 chips are acceptable is very small i.e. less than 0.000001
