Given:

3x - 2

To find:

Describe the parts of the expression

Solution:

3x - 2Let us consider, f (x) = 3x - 2

The standard equation of the straight line is given by, y = mx + c

comparing the given equation with straight line equation, we get,

f (x) = y

m = 3

c = -2

m is the gradient of line

c is the y intercept (the graph crosses the y - axis)

A student has a rectangular photograph with side lengths of 5 inches and x inches The area of the rectangle is 33 square inches.
Airida [17]

Answer:

1.32

total area = 33

33/5 1/2 = 6 .         X=6

5 1/2 x 1/2 = 2.75 .       6 x 1/2 = 3

2.75 x 3 = 8.25

new area = 8.25

A farmer knows that a grocery store will reject a shipment of his vegetables if more than 4% of the vegetables contain blemishes
kykrilka [37]

Answer:

Assumption A is violated

Step-by-step explanation:

x = number of blemishes = 8

n = sample size = 150

proportion = x/n = 8/150 = 0.0533

1. large counts: np> 10

= 150 * 0.0533 >10

= 7.995 > 10

this assumpton is obviously violated. <em><u>7.995 is not greater than 10</u></em>

<em><u></u></em>

2. Large Counts: n(1 - p) > 10

150(1-0.0533)>10

150-7.995 > 10

142.005> 10

there is no violation. The assumption is satisfied

3. This assumption is satisfied. this is because the tomatoes were selected using simple random sampling.

4. 10% of the population = 0.1 * 2000 = 200

the sample size = 150

150 < 200

this assumption is satisfied

<em><u></u></em>

There are ten candidates for a job. The search committee will choose three of them, and rank the chosen three from strongest to
saul85 [17]

Answer:

720

Step-by-step explanation:

Since we are choosing a subset of 3 people from a set of 10 people, and arranging the 3 people according to relative strength, the answer can be obtained by computing P(10,3).

 

 P(10,3)=10! / (10-3)!

= 10!/7!

Rewrite  10 !  as  

10 * 9  * 8  * 7 !  / 7!

Cancel the common factor of  7 !  and divide ( 10  * 9 * 8 ) by  1

10  * 9  * 8 = 720
