Fractions: three oil tankers together contain 37 5/7 litres of oil. If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

ale4655 [162]

Step-by-step explanation:

It is given that, three oil tankers together contain 37 5/7 litres of oil.

Total volume of oil is $\dfrac{264}{7}\ L$

If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

Oil in first tanker is $\dfrac{157}{14}\ L$

Oil in second tanker is $\dfrac{87}{7}\ L$

Oil in first and second tanker is :

$\dfrac{157}{14}\ L+\dfrac{87}{7}\ L=\dfrac{331}{14}\ L$

Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )

$=\dfrac{264}{7}\ L-\dfrac{331}{14}\ L\\\\=\dfrac{197}{14}\ L$

Hence, this is the required solution.

Solve for x, given the equation Square root of x-5+7=11

denis-greek [22]

$\sqrt{x-5+7} = 11\\x-5+7 = 11^2\\x-5+7 = 121\\x + 2 = 121\\x = 119$

Check the answer:

$\sqrt{119-5+7} \\\sqrt{114+7} \\\sqrt{121} \\11$

This answer is correct,

x = 119

For the straight line defined by the points (2, 55) and (4, 91), determine the slope and y-intercept. do not round the answers.

mixas84 [53]

Hello : let A(2,55) B(4,91)<span>
the slope is : (YB - YA)/(XB -XA)
(91-55)/(4-2) = 36/2 =18
an equation is : y-55 = 18(x-2)</span>

<span> y-intercept when : x = 0 : y - 55 = 18(0-2)
y-55 = -36
y = 55-36 = 19</span>

When Isaac commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 44 minutes and a s

mario62 [17]

Answer:

[34,54]

Step-by-step explanation:

-The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.

Where:

68% is the first standard deviation
95% is the second standard deviation about the mean
99.7% is the 3rd standard deviation about the mean.

-Therefore. the middle 95% interval is calculated as:

$CI=\mu+2\sigma\\\\=44\pm 2(5)\\\\=44\pm 10\\\\=[34,54]$

Hence, the interval is [34,54]
