P=4.1

7(p-9)= -34.3 use the distributive property
7p + (- 63 )= -34.3 get rid of the -63 by adding 63 to both sides
7p = 28.7 isolate them variable (divide each side by seven)
P=4.1

What is the angle, in radians, of arcsin(1/2)

ki77a [65]

$\frac{\pi}{6}$

When you are asked what is the sin of π/6, or 30 degrees, you would look at the special triangle (30-60-90) to see that sin, or opposite over hypotenuse, of π/6 is 1/2. Arcsin, or csc, will present you with the ratio, 1/2, and ask for the angle. It's essentially working the question backwards.

Suppose 44% of the students in a university are baseball players. If a sample of 736 students is selected, what is the probabili

zaharov [31]

Required probability is 0.8990

Given that,

p = 0.44

1 - p = 0.56

n = 736

$\mu_\hat{p}} = p = 0.44\\\sigma_\hat{p}} = \frac{p*(1-p)}{n} = \sqrt(\frac{0.44*0.56)}{736} ) =$ 0.01830

Converting Normal distribution to standard normal because A normal distribution is determined by two parameters the mean and the variance. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. Hence it's easy to work with standard normal distribution.

P(0.14< $\hat{p}$ <0.47) = P((0.41-0.44)/0.01830) < $\frac{\hat{p} - \mu _{\hat{p}} }{\sigma _{\hat{p}} }$ <(0.47-0.44)/0.01830

Using normal algebra we get:

= P(-1.64 < z < 1.64)

= P(z < 1.64) - P(z < -1.64)

= 0.9495 - 0.0505

= 0.8990

Thus, required probability is 0.8990

A computer manufacturer has found that its expenditure rate per day (in hundreds of dollars) on a certain type of job is given b

Anna35 [415]

Answer:

The expenditure would be $ 8600

Step-by-step explanation:

If the cost is given by the function

C(x)= 10x + 6 where x is the number of days

The cost for 1 day would be

C(1)= 16 *100 = 1600 $ ( the expenses are in hundreds of dollars)

Then Putting x= 8 in the given equation we get

C(8)= 10(8) + 6

= 86

Multiplying 86 by 100 because expenditure rate per day is in hundreds of dollars

The expenditure would be $ 8600

Suppose that a large mixing tank initially holds 900 gallons of water in which 50 pounds of salt have been dissolved. Another br

borishaifa [10]

Answer:

dA/dt= 12-2A(t)/900+t

Step by step Explanation:

Given:

rate of 3 gal/min

concentration of the solution entering is 4 lb/gal,

The equation of the solution can be expressed as

dA/dt = R(1)- R(2)

Where R(1)=( concentration of the salt at inflow* rate of input of given brine)

R(2)= ( concentration of the salt at inflow* rate of output of given brine)

R(1)= 3 gal/min× 4 lb/gal=12Ib/min

But the solution is been pumped slowly, the rate of the accumulation can calculated as;

(3 gal/min- 2 gal/min)=1gal/min

But after t min we will be having 900+t gallons present in the tank
