Answer:

Option A , (0, 20); y equals one over eighty times x squared plus 20

Step-by-step explanation:

The equation of parabola is given by  

(X-h)^2 = 4p(Y-k)^2

In this case h = 0

So we get  

Y = X^2/4P +k

Focus point is (h, p+k) , p+k = 40

Hence h, k = (0,20)

P = 40-k = 20

Equation Y = X^2/80 +20

Hence, option A is correct

How many subsets of the set of divisors of 72 contain only composite numbers? For example, {8,9} and {4,8,12}$ are two such sets
kykrilka [37]

Answer:

257

Step-by-step explanation:

The divisors of 72 which are composite number are

4,6,8,9,12,18,36,72 (composite numbers are those numbers which are formed by the multiplication of two whole numbers}

So the total number of divisors which are composite are = 8

So total number of subset =2^n=2^8=256

In question it is said that also include empty set in count

So total number of subset =256+1=257

Assume that military aircraft use ejection seats designed for men weighing between 141.8 lb and 218 lb. If​ women's weights are
Mariulka [41]

Answer:

P(141.8

And we can find this probability with this difference and using the normal standard table:

P(-0.639

Then the answer would be approximately 55.3% of women between the specifications. And that represent more than the half of women

Step-by-step explanation:

Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:

X \sim N(173.6,49.8)  

Where \mu=173.6 and \sigma=49.8

We are interested on this probability

P(141.8

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(141.8

And we can find this probability with this difference and using the normal standard table:

P(-0.639

Then the answer would be approximately 55.3% of women between the specifications. And that represent more than the half of women

A car traveled a distance of 126 miles in 3 hours. Traveling at the same speed, what distance would this car travel in 7 hours?
Arte-miy333 [17]
First method: by the rule of three:
126 miles---------------------3 hours
x---------------------------------7 hours

x=(126 miles * 7 hours) / 3 hours=294 miles.

Answer: 294 miles.

Second method:
Speed=distance/ time           ⇒distance=speed x time

We calculate the speed of the car:
Speed=126 miles/3 hours= 42 miles/hour.

Data: 
Speed=42 miles/hour
time=7 hours

Distance=speed x time
Distance=(42 miles/hour)(7 hours)=294 miles

answer: 294 miles.
