A computer manufacturer shipped a total of 50 machines to its two warehouses, one in west and one in east. It cost 20$ per machi
Natalka [10]
E + w = 50.....w = 50 - e
25e + 20w = 1090

25e + 20(50 - e) = 1090
25e + 1000 - 20e = 1090
25e - 20e = 1090 - 1000
5e = 90
e = 90/5
e = 18 <=== the east got 18

w = 50 - e
w = 50 - 18
w = 32 <=== the west got 32

The graph shows the amount of a medicine min milligrams, remaining in a patient's body hours after receiving an injection . The
aksik [14]

An exponential function is a function defined by y = ab^x, where a represents the initial value, and b represents the rate

<h3>(a) The factor at which the medicine decreased, in 1.5 hour</h3>

From the graph, we have the following ordered pairs

(x,y) = (0,270) and (1.5,80)

Given that:

y = ab^x

At point (0,270), we have:

ab^0=270

a= 270

At point (1.5,80), we have:

ab^{1.5} = 80

Substitute 270 for a

270b^{1.5} = 80

Divide both sides by 270

b^{1.5} = 0.2963

Take 1.5th root of both sides

b =0.44

Hence, the medicine decrease in the hour and half at a factor of 0.44

<h3>(b) The factor at which the medicine decreased in the first half hour, and the first hour</h3>

In (a), we have:

The decay factor (b) to be 0.44

This represents the factor at which the medicine decreased throughout.

Hence, the medicine decrease in the first half hour, and the first hour at a factor of 0.44

<h3>(c) The exponential equation</h3>

In (a), we have:

a= 270

b = 0.44

So, the exponential equation is:

y =270 * 0.44^x

In terms of m and h, we have:

m =270 * 0.44^h

Hence, the equation relating m to h is m =270 * 0.44^h

80% of people those who purchase pet insurance are women. If the owners of 9 pet insurance are randomly selected, then find the
Luba_88 [7]

The probability that exactly 6 out of them are women is 0.176

According to the statement

Number of selected pet owner randomly is 9. So, Here in this case n=9.(number of randomly selected owners).

Number for which have to find the probability is 6. So, Here in this case x=6.

Find the probability by a use of BINOMIAL THEOREM

So, n!/((n-x)!*x!) = 9!/((9-6)!*6!) = 84

Now, find out the probability of success p and probability of failure (1-p)=q.

From here we get p = 0.8 and q= 0.2

Now, use  p^x = (0.8)^6 = 0.2621

Then use q^(n-x) = (0.2)^(9-6) = 0.008

Now, Multiply the results obtained to get the probability is

84*0.2621*0.008 = 0.176

So, The probability that exactly 6 out of them are women is 0.176

There are 784 gallons in 100 cubic feet of water. How many gallons of water are in this reservoir if it is 56% full?
Burka [1]
We know that

step 1
find the volume of reservoir
[volume of reservoir]=15*20*10-----> 3000 ft³

step 2
find the volume of water in the reservoir
<span>if it is 56% full
</span>then
volume of water is------> .56*3000----> 1680 ft³

step 3
convert ft³ to gal
if 784 gal------------> 100 ft³
 X--------------> 1680 ft³
X=1680*784/100-------> X=13.171.2 gal

the answer is
13171.2 gal
