Answer: Delete the point (0, 4)

<u>Step-by-step explanation:</u>

Your line for y = (1/3)x + 4 is correct.

m=1/3 b=4

Start at (0, 4) and draw a line through a point up 1 and 3 to the right (3, 5).

Your line for x = 6 is correct.

A vertical line through (6, 0), (6, 1), (6, 2), ...

Your point for (6, 6) is correct.

x=6, y=6

Your error is that you used the dot tool to plot a point for (0, 4). You DO need this point to create the line y = (1/3)x + 4, however the instructions do not state to mark this coordinate with a dot.

Mrs. Smith decides to buy three sweaters and a pair of jeans. she had $120 in her wallet. if the price of jeans is $35, what is

mylen [45]

Answer:

The highest possible price of a sweater is $28.33

Step-by-step explanation:

We already know that price $j$ of jeans is $35.Let's say Mrs.Smith buys 3 sweaters for $p$ dollars each, and since her budget is $120 we have the inequality:

$3p+j\leq 120\\ \\\\=3p+35\leq 120$

Therefore

$p\leq 28.33$

Thus the maximum price of a sweater is $28.33

Answer:

Standard error = 0.4

Step-by-step explanation:

Step 1

We find the Standard Deviation

The formula = √(x - mean)/n - 1

n = 15

Mean = 1.93 hours

= √(0- 1.93)² + (0-1.93)² +(0- 1.93)²+( 0- 1.93)²+ (1- 1.93)² + (1- 1.93)² +(1 - 1.93)² +(2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + ( 2 - 1.93)² +(4 - 1.93)² +(4 - 1.93)² + (5 - 1.93)²/15 - 1

= √(3.737777776 + 3.737777776 + 3.737777776 + 0.871111111 +0.871111111 + 0.871111111 + 0.004444444445+ 0.004444444445 + 0.004444444445 + 0.004444444445 + 0.004444444445 + 1.137777778 + 4.271111112 + 4.271111112 + 9.404444446)/15 - 1

= √2.352380952

= 1.533747356

Step 2

We find the standard error

The formula = Standard Deviation/√n

Standard deviation = 1.533747356

n = 15

= 1.533747356/√15

= 1.533747356 /3.87298334621

= 0.39601186447

Approximately = 0.4

Therefore, the standard error is 0.4

kim can mow the greens at the golf course twice as fast as shayla can. Working together, they can mow the greens in 4 hours. How

anyanavicka [17]

Answer: Kim can mow the greens alone in 6 hours.

Step-by-step explanation:

Let K be the rate Kim mows the greens, and S the rate for Shayla. The rates K and S will be in greens/hour.

We know they can mow 1 green in 4 hours. We can state this as a sum of their rates times the 4 hours equals one green:

(4 hours)*(K + S) = 1 green

We are told that K = 2S [Kim is twice as fast as Shayla]

Subsititute:

(4 hours)*(K + S) = 1 green

(4 hours)*(2S + S) = 1 green

4*(2S + S) = 1 green

12S = 1 green

Shalya's rate is 1 green/12 hours

Kim is twice as fast: K = 2S

Kim's rate is 1 green/6 hours.
