Answer:

10.8 miles

Step-by-step explanation:

The distance between (-3, -4) and (3, 5) can be found using the distance formula.

d = √((x2 -x1)^2 +(y2 -y1)^2)

d = √((3 -(-3))^2 +(5 -(-4))^2) = √(6^2 +9^2) = √117

d ≈ 10.8

It is about 10.8 miles from the mall to the park.

A certain process for manufacturing integrated circuits has been in use for a period of time, and it is known that 12% of the ci

enyata [817]

Answer:

(a) No the conclusion is not justified.

b. No

c. Two defective circuits in the sample

Step-by-step explanation:

Ans: (a) No the conclusion is not justified. What is important is the percentage population of defectives;

the sample proportion is only an approximation. The population proportion

for the new process may be more than or less than that of the old process. We can decide to pick two hundred samples and discover that the number of defects is greater than the previous process

(b)

.For the defectives, the population proportion for the new process may be 0.12 or more,

although the sample of defectives is just 11 out of 100

(c) Two defective circuits in the sample. This is because the probability of having two defects from the 100n samples is less than having 11 defects

Which lists the ratios in order from least to greatest?

lara [203]

Answer:

The answer is D.) 1:6, 7:36, 2:9

Step-by-step explanation:

I pretty just put these into decimal form. (Dividing the numerator by the denominator)

So 1:6 is equal to .166

7:36 is equal to .199

And finally, 2:9 is equal to .222

The bigger the number, the greater it is.

Pauline travels between two cities. First she drives for 40 minutes at an average speed of 88 km/hr then for 40 minutes at an av

Scilla [17]

Pauline's average speed for this trip is 64 km/hr.

Explanation

First we will convert each 'minutes' into 'hours' . So......

40 minutes = $\frac{40}{60}hours =\frac{2}{3} hours$ and 23 minutes = $\frac{23}{60}hours$

Now, $Distance = Speed* Time$

So, the distance traveled for first 40 minutes at 88 km/hr speed $=(88* \frac{2}{3})km = 58.67 km$ ,

the distance traveled for next 40 minutes at 75 km/hr speed $=(75*\frac{2}{3})km=50 km$ and

the distance traveled last 23 minutes at 49 km/hr speed $=(49*\frac{23}{60})km = 18.78 km$

So, the total distance traveled $=(58.67+50+18.78) km = 127.45 km$

She spends 17 minutes eating lunch and buying gas.

So, the total time taken for the trip $= (40+40+17+23)minutes = 120 minutes= 2 hours$

Thus, Pauline's average speed for this trip = (Total distance / Total time) $=(\frac{127.45}{2})km/hr = 63.725 km/hr =64 km/hr$ (Rounded to the nearest km/hr)
