The average cost of tuition, room and board at small private liberal arts colleges is reported to be $8,500 per term with a stan

Svetlanka [38]

Answer:

z=3.8196

Step-by-step explanation:

-We notice that this is a normal distribution problem.

-Given the mean is $8500, standard deviation is $1200 , and n=350, the critical z-value using alpha=0.05 is calculated as:

$z=\frac{x-\mu_o}{\sigma/\sqrt{n}}\\\\=\frac{8745-8500}{1200\sqrt{350}}\\\\\\=3.8196$

Hence, the test statitic is z=3.8196

Simplify 3{[3(9 – 2)] + [7(8 – 1)]}

Mekhanik [1.2K]

Answer:

210

Step-by-step explanation:

Use the order of operations pemdas( parenthesis, exponent, multiply, divide, add, subtract)

first do everything within the parenthesis.

3 ( ( 3 (9-2) ) + ( 7 (8-1) ) )

3 ( ( 3 (7) + ( 7 ( 7 ) ) )

3 ( ( (21) + (49) ) ) )

3 ( ( 21 + 49 ) )

3 ( 70 )

3 (70) = 70 + 70 + 70 = 140 + 70 = 210

A tangent to the curve y=6x-x² cuts the x axis at point P. Find the coordinates of P. Help me calc the coordinates please

Ilya [14]

We know that the line is tangent at the point (2,8)

The derivative of the function at x=2 is

$f'(x) = 6-2x \implies f'(2) = 6-4=2$

So, the tangent line passes through the point (2,8) and has slope 2. The equation is

$y-8 = 2(x-2) \iff y = 2x+4$

This line crosses the x axis where y=0:

$0 = 2x+4 \iff 2x = -4 \iff x = -2$
