Let's convert the fractions to the same denominator

\frac{4}{5} =  \frac{24}{30}
\frac{1}{6} =  \frac{5}{30}

this means that when 190 liters, or 19/30 of the water was drawn off, there was 1/6 left.

let's create an equation and solve for x. we know that 190 is equal to 19/30 of the the tank. what about 1/30? we nee to divide each side by 19 to find out.

190/10 would be 19. this means that 1/30 of the tank is 19 liters.

to find the full tank, or 30/30 of the tank, multiply 19 by by 30, to get 570.

the full capacity of the tank is 570 liters

hope this helped!

p.s. can i have brainliest?

stiks02 [169]

Answer:

a) 0.3277

b) 0.0128

Step-by-step explanation:

We are given the following information in the question:

N(2750, 560).

Mean, μ = 2750

Standard Deviation, σ = 560

We are given that the distribution of distribution of birth weights is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

a) P (less than 2500 grams)

P(x < 2500)

P( x < 2500) = P( z < \displaystyle\frac{2500 - 2750}{560}) = P(z < -0.4464)

Calculation the value from standard normal z table, we have,  

P(x < 2500) = P(z < -0.4464) = 0.3277 = 32.77\%

b) P ((less than 1500 grams)

P(x < 1500)

P( x < 1500) = P( z < \displaystyle\frac{1500 - 2750}{560}) = P(z < -2.2321)

Calculation the value from standard normal z table, we have,  

P(x < 1500) = P(z < -2.2321) = 0.0128 = 1.28\%

The graph of the function f(x)=−4(x−3)2+9 will be a parabola opening in which direction?
sesenic [268]

Answer:

downwards

Step-by-step explanation:

the equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

• if a > 0 then parabola opens upwards

• if a < 0 then parabola opens downwards

for

f(x) = - 4(x - 3)² + 9 with a = - 4 < 0 , then

the parabola opens downwards
