Answer: $y + 6 = \frac{1}{2}(x - 6)$

Step-by-step explanation:

Point-slope formula: $y - y1 = m(x - x1)$

Plug in the numbers: $y - -6 = \frac{1}{2}(x-6)$

Clear the double negatives: $y + 6 = \frac{1}{2}(x - 6)$

2. A recipe says that 6 spring rolls will serve 3 people. Complete the table as you answer the questions. Be prepared to explain

LuckyWell [14K]

Answers:

a. 0.5 people

b. 10 spring rolls will serve 5 people, 16 spring rolls will serve 8 people, 25 spring rolls will serve 12.5 people

c. n/2 or 1/2 of n

Step-by-step explanation:

if 6=3p, p representing each person, then we find that 2 spring rolls serve 1 person, so 1 spring roll serves 0.5 people!

if 1=0.5p, then p is 1/2 of the amount of spring rolls.

Divide each of the amount of spring rolls by 2.

10=5p

16=8p

25=12.5p

n=n/2

The variable p is important, as to show that it's the amount of people.

Hope this helps!

The commercial for the new Meat Man Barbecue claims that it takes 10 minutes for assembly. A consumer advocate thinks that the c

Andrews [41]

Answer:

There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes (P-value=0.009).

Step-by-step explanation:

We have to perform an hypothesis test on the mean.

The null and alternative hypothesis are:

$H_0: \mu=10\\\\H_1: \mu \neq 10$

The significance level is $\alpha=0.05$ .

The test statistic t can be calculated as:

$t=\frac{M-\mu}{s/\sqrt{N} } =\frac{11.2-10}{3.1/\sqrt{50} }=2.737$

The degrees of freedom are:

$df=N-1=50-1=49$

The P-value (two-tailed test) for t=2.737 and df=49 is P=0.00862.

This P-value (0.009) is smaller than the significance level, so the effect is significant. The null hypothesis is rejected.

There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes.

Aleks [24]

To solve this problem, we must recall that the formula for money with compound interest is calculated as:

Total = Principal × ( 1 + Rate ) ^ n

Total = $2,200 × ( 1 + 0.024 ) ^ 1

Total = $2,252.80
