Julie wrote the rate $108 in 6 weeks as a unit rate.Find her mistake and correct it.

natima [27]

Well for starters that would be $108/6 weeks when a unit rate is anything over one. To put it as a unit rate (how many dollars per hours) you just divide $108 by 6 (since you would divide 6 by 6 to get) and the unit rate would end up being $18 per hour.

Rasek [7]

Answer:

0.6604

Step-by-step explanation:

Given that a market research firm knows from historical data that telephone surveys have a 36% response rate.

Sample size of random sample = 280

We know for samples randomly drawn of large size sample proportion follows a normal distribution with mean= sample proportin and std error

= $\sqrt{\frac{pq}{n} }$

Substitute p = 0.36 and q = 1-0.36= 0.64

p follows N with mean = 0.36 and std dev = $\sqrt{\frac{0.36*0.64}{\sqrt{280} } } \\=0.0287$

Using normal distribution values we can find\

$P(33.5p.c. < p < 39pc)\\= P(0.335$

Write an equation for the line that is parallel to the given line and passes through the given point

Evgesh-ka [11]

Answer:

y = 2x + 2

Step-by-step explanation:

The equation ofa line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 4 ← is in slope- intercept form

with m = 2

Parallel lines have equal slopes , thus

y = 2x + c ← is the partial equation

To find c substitute (3, 8) into the partial equation

8 = 6 + c ⇒ c = 8 - 6 = 2

y = 2x + 2 ← equation of parallel line
