Answer:

lower 95% Cl is 0.292

Step-by-step explanation:

p^ = 0.4783

n = 23

for 95% Cl,

z = 1.9600

Inputting all the available data into P as attached below

LCL = 0.292

UCL = 0.670

therefore, lower 95% Cl = 0.292

Solve both equations.

lakkis [162]

Equation 1:

Answer:

x = 1.22

Step-by-step explanation:

$\frac{5x-1}{8} -\frac{5-7x}{2} = \frac{3(6-x)}{6}$

$\frac{2(5x-1) - 8(5-7x)}{16} = \frac{3(6-x)}{6}$

$\frac{(10x-2) - (40-56x)}{16} = \frac{3(6-x)}{6}$

$\frac{(10x-2-40+56x)}{16} = \frac{3(6-x)}{6}$

$\frac{(66x-42)}{16} = \frac{3(6-x)}{6}$

$\frac{(66x-42)}{16} = \frac{(18-3x)}{6}$

$(66x-42) \times 6 = (18-3x) \times 16$

$(396x-252) = (288-48x)$

$(396x +48x) = (288+252)$

$444x = (540)$

$x = \frac{540}{444}$

x = 1.22

Equation 2:

Answer:

x = -13.97

Step-by-step explanation:

$\frac{x}{3} - \frac{7(x-2)}{9} = 4- \frac{2x-5}{6}$

$\frac{9x-3(7(x-2))}{27} = 4- \frac{2x-5}{6}$

$\frac{9x-3(7x-14))}{27} = 4- \frac{2x-5}{6}$

$\frac{9x-(21x-42))}{27} = 4- \frac{2x-5}{6}$

$\frac{9x-(21x-42)}{27} = \frac{24 - (2x-5)}{6}$

$\frac{-12x+42}{27} = \frac{-2x+29}{6}$

$(-12x+42) \times 6 = (-2x+29) \times 27$

$(-72x+252) = (-34x+783)$

$(252-783) = (-34x +72x)$

$(-531) = (38x)$

$x =\frac {-531}{38}$

x = -13.97

Mrs.Rowan alotted 30 mintues at the beginning of class for her students to complete an exam. Tha lst student took 42 minutes to

shusha [124]

Hey there!

$\large\boxed{40\%}$

To find percent error, we find the difference between the prediction and the actual value. We take that difference, divide it by the prediction, and multiply it by 100.

So let's find the difference.

42 - 30 = 12

Divide the difference, which is 12, by 30.

12 ÷ 30 = 0.4

Multiply this by 100 to get the percent.

0.4 x 100 = 40

The percent error is 40%.

Hope this helps!
